Answer:8.65

Step-by-step explanation:

Answer:

The statement is false.

Step-by-step explanation:

Here we need to remember some things:

Integer numbers are closed under multiplication.

This means that for two integers a and b, the product a*b is also an integer.

A rational number is a number that can be written as the quotient of two integer numbers.

An irrational number is a number that can't be written as the quotient of two rational numbers.

Now let's see the statement:

"The product of two rational numbers is irrational."

The product of two rational numbers is written as:

[tex]\frac{a}{b} *\frac{c}{d}[/tex]

Where a, c, b, and d are integers.

We can rewrite that product as:

[tex]\frac{a*c}{b*d}[/tex]

Because of the first property, we know that a*c is an integer, and b*d is also an integer, so here we have a quotient of two integer numbers, so this is a rational number.

Then the product of two rational numbers is a rational number.

Then the statement is false.

Answer: 8 whole gallons.

Step-by-step explanation: If you have only $27.00 and you need to buy gas, but each gallon is $3.15, then you just need to divide your total amount ($27.00) by your cost per gallon ($3.15), and you will get about 8.6 gallons, however this question asks for how many WHOLE gallons you can get, so all you need to do is round down to fit your budget, leaving money for only 8 whole gallons.

WORK: ($27.00) / ($3.15) = 8.6 gallons

c)y=|x-2|+1

Answer:

C) y = 2x

Step-by-step explanation:

That's the only equation that if x = 0, y will = 0

Answer:

C

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

A

y = x + 1 ← has a y- intercept of 1

B

y = x - 1 ← has a y-intercept of - 1

C

y = 2x ← has a y- intercept of 0

D

y = 2x + 2 ← has a y- intercept of 2

Thus y = 2x passes through the origin → C

Answer:

r = 3 1/4

Step-by-step explanation:

Here, we want to find the value of r given the values

Firstly, we will write r as the subject of the formula

U = π ( r + h)

U/π = r + h

r = U/π - h

Now substitute;

U = 16 1/2 = 33/2

h = 2

π= 22/7

r = 33/2/22/7 - 2

r = (33/2 * 7/22) - 2

r = 21/4 - 2

r = (21-8)/4

r = 13/4 = 3 1/4

The distance from point A to B is 1 foot.

Given,

There are 12 steps in the staircase.

We need to find the distance of the steps.

The distance is given by AB.

Feet is the plural form of the foot.

It states that in a right-angle triangle the hypotenuse is equal to the squares of the other two sides.

If the hypotenuse is H and the other two sides are A and B.

H² = A² + B²

We have a figure,

Where it is in a right-angled triangle.

Two sides are given: 7.5 inches and 10 inches.

And hypotenuse  = AB.

Applying the Pythagorean theorem.

7.5² + 10² = AB²

AB² = 56.25 + 100

AB² = 156.25

AB = [tex]\sqrt{156.25}[/tex]

AB = 12.5 inches

Now,

AB = 12.5 inches.

We need to convert it into feet.

12 inches =1 foot

Multiplying 12.5/12 on both sides.

12.5/12 x 12 inches = 12.5/12 x 1 feet

12.5 inches = 1.0416 feet

Rounding to the nearest tenth we get,

12.5 inches = 1 feet

AB = 1 feet

Thus the distance of the staircase from point A to B is 1 foot.

Answer:

B. 260 miles

Step-by-step explanation:

The important thing to consider here is the maximum amount of time she can spend driving. Since she will spend 2 hours at the park and want to be gone no more than 6 hours, this number is 4 hours.  

This means she can spend 2 hours on the way to the park and 2 hours back. Her maximum distance, therefore, is 2 hours times an average speed of 65 miles per hour

Therefore:

2x ≤65 * 4

2x ≤ 260

x ≤ 130

Her maximum distance is 2 hours x 65 mph = 130 miles.

Answer:

Alexandria can choose any distance not more than 130 miles from her house to the park.

Step-by-step explanation:

Let Alexandria takes time 't' hours to walk from home to the park and distance between park and home is 'x' miles.

If she averages 65 miles per hour "to and fro" from her home to the park then the inequality that will represent this situation will be

2x ≤ 65t   [ Distance = Speed × time ]

If she wants to hike for 2 hours and maximum time spent to  reach the park is 6 hours

Then the maximum time spent by her to reach the park from her home should be = 6 - 2 = 4 hours.

By placing the value of t = 4 in the inequality

2x ≤ (65×4)

2x ≤ 260

x ≤ 130

Therefore, Alexandria can choose any distance not more than 130 miles from her house to the park.

Alexandria wants to go hiking on Saturday. She will consider these conditions when she chooses which of several parks to visit: • She wants to hike for 2 hours. • She wants to spend no more than 6 hours away from home. • She can average 65 miles per hour to and from the park. Write and solve an inequality to find possible distances from Alexandria’s home to a park that satisfies the conditions.

The actual answer is 180 miles if anyone was wondering. I know the other answer is "Verified" but its wrong. me and the other people who trusted it know that. good luck.

Alexandria wants to go hiking on Saturday. To choose from several parks she could go to, she considers these conditions.

Favorite Answer

The distance from Alexandria's home to a park has to be within 130 miles.

Let h = time of Alexandria's hike = 2 hours.

Let p = time spent to get to park (driving)

h + 2p (since it is round trip - to the park and back) <= 6 hours (time to spend away from home)

h = 2, thus

2 + 2p <= 6

2p <= 4

p <= 4/2 = 2

Thus, she has to spend 2 hours to get to the park, and spend 2 hours to get back home.

distance to the park <= speed of driving x time of getting to park

                             <= 65 miles per hour x 2 hours

                             <= 130 miles

Thus, we get the 130 miles.

The correct option is B. 260 miles. and the required inequality is [tex]2+\dfrac{D}{65} \leq 6[/tex].

Given, Alexandria wants to go hiking based on the conditions.

The average speed of Alexandria is 65 miles per hour.

Since she wants to hike minimum of 2 hours, so minimum distance covered by her will be  [tex](65\times2=130) \\[/tex] miles.

Now time [tex]t[/tex] required to cover [tex]D[/tex] distance with the speed of 65 miles per hour will be  [tex]\frac{D}{65}[/tex] hours.

But She doesn't want to spend more than 6 hours away from home,

So the inequality becomes,

[tex]2+\dfrac{D}{65} \leq 6[/tex].

On solving for D,

[tex]\dfrac{D}{65} \leq 6-2[/tex]

[tex]D\leq 4\times65\\\\\D\leq 260[/tex]

Hence the Distance traveled by Alexandria must not exceed by 260 miles.

Therefore the correct option is B. 260 miles. and the required inequality is [tex]2+\dfrac{D}{65} \leq 6[/tex].

Answer:

x= −7/5

Step-by-step explanation:

Step 1: Distribute and combine like terms

3(x−6)−8x=−2+5(2x+1)

(3)(x)+(3)(−6)+−8x=−2+(5)(2x)+(5)(1)(Distribute)

3x+−18+−8x=−2+10x+5

(3x+−8x)+(−18)=(10x)+(−2+5)(Combine Like Terms)

−5x+−18=10x+3

−5x−18=10x+3

Step 2: Subtract 10x from both sides.

−5x−18−10x=10x+3−10x

−15x−18=3

Step 3: Add 18 to both sides.

−15x−18+18=3+18

−15x=21

Step 4: Divide both sides by -15.

Answer:

a) A reduction

b) The scale factor is 1/2

Step-by-step explanation:

The vertices of the original figure, ABCD are;

A(-2, 4), B(4, 4), C(2, -2), and D(-4, -2)

The vertices of the image, A'B'C'D' are;

A'(-1, 2), B'(2, 2), C'(1, -1), and D'(-2, -1)

a) The length of the side AB = 4 - (-2) = 6 (Distance between points having the same 'x' or 'y' coordinates

The length of the side A'B' = 2 - (-1) = 3

The length of AB = 6 is larger than the length of A'B' = 3, therefore the image A'B'C'D' is a reduction of (is smaller) the figure ABCD

b) The scale factor = The ratio of the lengths corresponding sides of the image to the original figure;

∴ The scale factor =A'B'/AB = A'D'/AD = B'C'/BC = D'C'/DC

AD = √((-4 - (-2))² + (-2 - 4)²) = 2·√10

A'D' = √((-2 - (-1))² + (-1 - 2)²)  = √10

A'D'/AD= √10/(2·√10) = 1/2

Therefore, given that the coordinates of the preimage are 2 × the coordinates of the image, we have;

The scale factor = A'B'/AB = B'C'/BC = D'C'/DC = A'D'/AD =1/2

The scale factor is 1/2, therefore, we multiply the dimensions of the original figure by 1/2 to get the dimensions of the image.

The scale factor = 1/2.
