(z): c = 1/8 z

Answer:

1) 1/2 + 1/4 = 2/4 + 1/4 = 3/4

2) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 9 is 63, so we can write:

3/7 * 9/9 + 2/9 * 7/7 = 27/63 + 14/63 = 41/63

3) To add these fractions, you need to find a common denominator. The smallest common multiple of 5 and 15 is 15, so we can write:

3/5 * 3/3 + 1/15 * 1/1 = 9/15 + 1/15 = 10/15

But we can simplify this fraction by dividing both the numerator and denominator by 5:

10/15 = 2/3

4) To add these fractions, you need to find a common denominator. The smallest common multiple of 9 and 8 is 72, so we can write:

1/9 * 8/8 + 7/8 * 9/9 = 8/72 + 63/72 = 71/72

5) To add these fractions, you need to find a common denominator. The smallest common multiple of 7 and 21 is 21, so we can write:

6/7 * 3/3 + 2/21 * 1/1 = 18/21 + 2/21 = 20/21

6) To add these fractions, we need to find a common denominator first. The smallest number that both 6 and 10 divide into is 30. So, we convert 4/6 to 20/30 by multiplying both the numerator and denominator by 5, and we convert 2/10 to 3/15 by multiplying both the numerator and denominator by 3. Now we have:

20/30 + 3/15 = (20x1 + 3x2)/(30x2) = 23/60

Therefore, 4/6 + 2/10 = 23/60.

7) To add these fractions, we need to find a common denominator first. The smallest number that both 11 and 22 divide into is 22. So, we convert 1/11 to 2/22 by multiplying both the numerator and denominator by 2, and we convert 3/22 to 3/22 (it is already in terms of 22). Now we have:

2/22 + 3/22 = (2 + 3)/22 = 5/22

Therefore, 1/11 + 3/22 = 5/22.

8) To add these fractions, we need to find a common denominator first. The smallest number that both 4 and 20 divide into is 20. So, we convert 1/4 to 5/20 by multiplying both the numerator and denominator by 5, and we convert 8/20 to 8/20 (it is already in terms of 20). Now we have:

5/20 + 8/20 = (5 + 8)/20 = 13/20

Therefore, 1/4 + 8/20 = 13/20.

9) To add these fractions, we need to find a common denominator first. The smallest number that both 7 and 9 divide into is 63. So, we convert 4/7 to 24/63 by multiplying both the numerator and denominator by 3, and we convert 2/9 to 14/63 by multiplying both the numerator and denominator by 7. Now we have:

24/63 + 14/63 = (24 + 14)/63 = 38/63

Therefore, 4/7 + 2/9 = 38/63.

10) To add these fractions, we need to find a common denominator first. The smallest number that both 10 and 30 divide into is 30. So, we convert 6/7 to 18/30 by multiplying both the numerator and denominator by 3, and we convert 2/30 to 1/15 by multiplying both the numerator and denominator by 15. Now we have:

18/30 + 1/15 = (18x1 + 1x2)/(30x2) = 37/30

Therefore, 6/7 + 2/21 = 37/30.

we can simplify |x + 3| to x + 3 when x is greater than 5.

The absolute value function |x| is defined as the distance of x from zero on the number line. This means that |x| is always non-negative, so it can be expressed as a non-negative number.

In this case, we are given that x > 5, which means that x is greater than 5. If we add 3 to both sides of this inequality, we get:

x + 3 > 5 + 3

x + 3 > 8

This tells us that x + 3 is also greater than 8. Therefore, when x is greater than 5, the expression |x + 3| represents the distance of x + 3 from zero, which is equal to x + 3 itself because x + 3 is positive.

As a result, we can simplify |x + 3| to x + 3 when x is greater than 5.

The first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

To solve this problem, we can use trigonometry and create a system of equations based on the given angles and distances. Let's assume the distance between the dock and the first hotel is x meters and the distance between the dock and the second hotel is y meters.

Using the law of sines, we can relate the angles and distances:

For the first hotel:

sin(49°) = y / x     ...(Equation 1)

For the second hotel:

sin(56°) = x / y     ...(Equation 2)

We can rearrange Equation 1 to solve for y:

y = x * sin(49°)

Substituting this value of y into Equation 2:

sin(56°) = x / (x * sin(49°))

sin(56°) = 1 / sin(49°)

Now, we can solve for x by isolating it:

x = sin(56°) * sin(49°)

Plugging in the values and evaluating the equation:

x = 0.8290 * 0.7539

x ≈ 0.6246

Therefore, the distance between the dock and the first hotel (x) is approximately 0.6246 meters.

To find the distance between the dock and the second hotel (y), we can substitute this value back into Equation 1:

y = 0.6246 * sin(49°)

y ≈ 0.4931

Hence, the distance between the dock and the second hotel (y) is approximately 0.4931 meters.

In summary, the first hotel is approximately 0.6246 meters away from the dock, and the second hotel is approximately 0.4931 meters away from the dock.

The linear function rule that models the total cost y​ for any number of sweatshirts x would be: y = 9.50x

What is Algebraic expression ?

An algebraic expression is a combination of variables, constants, and mathematical operations such as addition, subtraction, multiplication, and division. It may contain one or more terms, with each term separated by a plus or minus sign. Algebraic expressions are used in algebra to represent mathematical relationships and formulas.

To write a linear function rule that models the total cost y​ (in dollars) for any number of sweatshirts x, we can use the equation of a line which is given as:

y = mx + b

where m is the slope of the line and b is the y-intercept.

In this case, the slope represents the cost per sweatshirt, which is $7.00, and the y-intercept represents the fixed cost, which is the shipping charge of $2.50. Therefore, the linear function rule that models the total cost y​ for any number of sweatshirts x can be written as:

y = 7x + 2.50

If the shipping charge applied to each sweatshirt, the linear function rule would change. In this case, the cost per sweatshirt would be the sum of the base cost of $7.00 and the shipping charge of $2.50, which is $9.50. Therefore, the linear function rule that models the total cost y​ for any number of sweatshirts x would be: y = 9.50x

Using the Law of Sines and Cosines, we get all possible values of ∠H are approximately 60.6° and 69.0°.

We can use the Law of Cosines to find the length of side GH

GH² = g² + h² - 2gh cos(G)

GH² = (9.3)² + (9.6)² - 2(9.3)(9.6)cos(109°)

GH ≈ 3.585 cm

Next, we can use the Law of Sines to find the measure of angle H

sin(H)/GH = sin(G)/HI

sin(H)/3.585 = sin(109°)/HI

sin(H) ≈ 3.585(sin 109°)/HI

H ≈ arcsin[3.585(sin 109°)/HI]

Since we do not know the length of side HI, we cannot determine the exact value of angle H. However, we can find the possible range of angle H by assuming that HI is the longest side of the triangle (making angle H the smallest) and the shortest side of the triangle (making angle H the largest).

If HI is the longest side, then H ≈ arcsin[3.585(sin 109°)/9.3] ≈ 60.6°

If HI is the shortest side, then H ≈ arcsin[3.585(sin 109°)/9.6] ≈ 69.0°

Therefore, the possible values of angle H are between approximately 60.6° and 69.0°.

The number of milligrams of sugar his spoon holds is 1250 milligrams.

To find out how many milligrams of sugar Chad's spoon holds, we first need to know how much sugar he removed in total. To do this, we can subtract the amount of sugar he needed (280 grams) from the amount he poured (295 grams).

295 grams - 280 grams = 15 grams

Next, we need to divide the total amount of sugar Chad removed (15 grams) by the number of spoonfuls he used (12).

15 grams ÷ 12 = 1.25 grams per spoonful

Finally, we can convert grams to milligrams by multiplying by 1000.

1.25 grams x 1000 = 1250 milligrams

Therefore, Chad's spoon holds 1250 milligrams of sugar.

A geometric sequence is a type of sequence where each term is found by multiplying the previous term by a constant factor. This means that each term is a multiple of the one before it. In contrast, an arithmetic sequence is a type of sequence where each term is found by adding a constant value to the previous term.

This means that each term is a sum of the one before it and a fixed value.

To answer your question, whether a geometric sequence will always grow faster than an arithmetic one depends on the values of the constant factor and fixed value in each sequence. In general, if the constant factor in a geometric sequence is greater than 1, the terms will grow at an increasingly faster rate than in an arithmetic sequence.

However, if the constant factor is between 0 and 1, the terms will grow at a decreasing rate, meaning that the sequence will actually grow more slowly than an arithmetic one.

It's important to note that the rate of growth is not the only factor to consider when comparing geometric and arithmetic sequences. The actual values of the terms in each sequence can also differ significantly, depending on the starting term and the values of the common ratio and common difference.

In some cases, an arithmetic sequence may actually have higher values than a geometric one, even if it grows more slowly.

In summary, whether a geometric sequence will always grow faster than an arithmetic one depends on the specific values of each sequence. However, in general, if the constant factor in a geometric sequence is greater than 1, it will grow faster than an arithmetic sequence.

Lee spent a total of 33 hours working on all the lawns, as calculated by multiplying the number of lawns for each size category by the respective time required for mowing, trimming, and sweeping.

In order to determine the total number of hours Lee spent working on all the lawns, we need to calculate the time for each task separately. For the average size lawn, Lee takes 1 hour to mow and 2 hours to trim and sweep, totaling 3 hours per lawn. For the large size lawn, Lee takes 3 hours to mow and 3 hours to trim and sweep, totaling 6 hours per lawn.

Given that Lee mowed, trimmed, and swept 5 average size lawns and 3 large size lawns in one week, we can calculate the total hours as follows:

Total hours for average size lawns = 5 lawns * 3 hours/lawn = 15 hours

Total hours for large size lawns = 3 lawns * 6 hours/lawn = 18 hours

Therefore, the total hours Lee spent working on all the lawns is 15 hours + 18 hours = 33 hours.

x = 0, π, 2π, 3π, 4π, 5π, 6π, π/3, 5π/3

These are the exact solutions of the given equation on the interval [0, 21). To find all exact solutions of the equation sec(x) sin(x) - 2 sin(x) = 0 on the interval [0, 21), we will use the factoring method:

First, we can factor out the sin(x) term:

sin(x) (sec(x) - 2) = 0

Now, we have two separate equations to solve:

1) sin(x) = 0
2) sec(x) - 2 = 0

For equation (1), sin(x) = 0 at x = nπ, where n is an integer. We need to find the values of n that give solutions in the range [0, 21):

0 ≤ nπ < 21
0 ≤ n < 21/π
n = 0, 1, 2, 3, 4, 5, 6

x = 0, π, 2π, 3π, 4π, 5π, 6π

For equation (2), sec(x) - 2 = 0, or sec(x) = 2. We know that sec(x) = 1/cos(x), so:

1/cos(x) = 2
cos(x) = 1/2

The values of x for which cos(x) = 1/2 in the range [0, 21) are x = π/3 and x = 5π/3.

Combining both sets of solutions, we have:

x = 0, π, 2π, 3π, 4π, 5π, 6π, π/3, 5π/3

These are the exact solutions of the given equation on the interval [0, 21).

The complete range of acceptable pressures, p, for the scuba tanks is 2,600 psi ≤ p ≤ 3,300 psi to ensure safe and enjoyable diving experiences.

Maintaining the correct pressure in scuba tanks is critical for safe and enjoyable diving experiences. If the pressure is too low, the diver may not have enough air to complete the dive and may be at risk of running out of air.

If the pressure is too high, the tank could rupture or explode, posing a significant danger to the diver. It is essential to keep the pressure within the acceptable range of 2,600 psi to 3,300 psi.

This means that the pressure of the scuba tanks must be greater than or equal to 2,600 psi and less than or equal to 3,300 psi.The inequality that expresses the complete range of acceptable pressures, p, in psi, for the scuba tanks is 2,600 psi ≤ p ≤ 3,300 psi.
