Answer: See explanation

Step-by-step explanation:

Monday

The sale price of the items was $41.40

Mrs. Bolden paid $2.48 in sales tax on her purchase.

Altogether, Mrs. Bolden paid $43.88 for the shirts and flip flops.

Tuesday

The price decreased by approximately 8%

3.44 ÷ 3.75 = 0.917

0.917 × 100 = 91.7

91.7 ≈ 92

100 - 92 = 8

8% of 3.75 is 0.3

3.75 - 0.3 = 3.45

3.45 ≈ 3.44

Wednesday

22 ¹/₂ yrs or 22 yrs if that's easier

127.5 ÷ 1500 = 0.085

0.085 × 100 = 8.5

100 - 8.5 = 91.5

4 1/4 = 4.25

91.5 ÷ 4.25 = 21.5294117647

21.5294117647 × 4.25 = 91.5

21.5294117647 ≈ 21 ¹/₂ yrs

Thursday

If she marked up the price by 40%, that means $15 is 60% the original/selling price.

60% of x = 15

0.6x = 15

Divide both sides by 0.6

x = 25

The selling price is $25

If you wanted to confirm, 0.6 × 25 = 15

Friday

3 jeans for $42 each

3 × 42 = 126

3 jeans for $126

5 shirts for $27 each

5 × 27 = 135

5 shirts for $135

126 + 135 = 261

6.5% of 261

0.065 × 261 = 16.965

16.965 to the nearest cent is 16.97

She would have to pay $16.97 for tax.

261 + 16.97 = 277.97

She won't have enough money to buy everything she wants since the total price would be over $275.

Answer:

20%, since 100 is 20% of 500.

Answer:

7 refills

Step-by-step explanation:

Answer:

So I'm guessing the original price was 8.95 and each refill was 1.50.

8.95 + 1.50r = 37.45

r = 19

You got 19 refills

Answer:

The answer is 47

Answer:

y=1/2x-3

Step-by-step explanation:

Answer:

The original price was 520

Step-by-step explanation:

To find this, we first need to note that we paid 75% of the price. This is because we took 25% off from the original. Now we take the price we paid and divide it by the percentage of it which we paid. This will give us the original price.

390/75% = Total

390/.75 = Total

520 = Total

Answer:

Answer:

49.2

Step-by-step explanation:

Answer:

Using trigonometric identities: A trigonometric identity is a relationship between trigonometric functions that we can use to find an exact value of a trigonmetric function.Using the unit circle: The unit circle is a circle with its center at the origin and a radius of 1 unit. If we place an angle, θ, with its initial side along the positive x-axis, then the point where the angle's terminal side intersects the unit circle is (cos(θ), sin(θ)).Using reference angles: Reference angles are the smallest angle that the terminal side of an angle makes with the x-axis. As it turns out, trigonometric functions of an angle and its reference angle have the same value, except that they may have different signs.

For example, suppose we want to find the exact value of tan(405°). First, we take a look at the angle 405° on a graph with the unit circle:

in this that the reference angle of 405° is 45°. We can use the fact that tangent is positive in the first quadrant and the rule for reference angles to deduce that tan(405°) = tan(45°). Then we can use the well-known fact that tan(45°) = 1 to get that tan(405°) = 1.

Answer:

1. Proportional

2. Not proportional

3. Proportional

Step-by-step explanation:

We have three questions with 2 ratios and are asked if they are proportional or not.

To define proportionality, basically its if the two ratios equal the same value when put in a certain way.

And that way is :

[tex]\frac{x}{y} =\frac{x}{y}[/tex]

You will substitute the numbers with the letters, in which you will cross multiply :

[tex]\frac{x * y}{x*y}[/tex]

So subtitute :

1.

[tex]\frac{1}{3} *\frac{7}{21}[/tex]

[tex]\frac{1*21}{7*3}[/tex]

[tex]21=21[/tex]

Therefore 1. is proportional.

2.

[tex]\frac{3}{4} *\frac{24}{18}[/tex]

[tex]\frac{4*24}{3*18}[/tex]

[tex]\frac{96}{54}[/tex]

96 = 54

Therefore 2. is not proportional.

3.

[tex]\frac{1}{5} *\frac{6}{30}[/tex]

[tex]\frac{1*30}{5*6}[/tex]

[tex]\frac{30}{30}[/tex]

30 = 30

Therefore 3. is proportional.

Answer:

Step-by-step explanation:

6 P = 342

To solve the question, you need to divide by 6

You don't multiply

The operation is division

The variable is the number of peanuts in each bag.

The answer is 57

The last two are incorrect.

x/p // 6 / end fraction

start fraction /p * end fraction /6

This doesn't make an awful lot of sense to me. But it is also untrue.

The variable P will never take 342

Answer:

[tex]7^{15}[/tex]

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex] , then

Answer:

9%

Step-by-step explanation:

Given data

Principal= 400

time= 4 months

r= 12%

SI= 12

SImeple interest

12=PRT/100

susbstitute

12= (400*r*4/12)/100

12SI= 400*r*0.333/100

12=133.2r/100

cross  multiply

1200= 133.2r

r= 1200/133.2

r= 9.009

Hence the rate is 9%

Answer:

Equation: 160 + 3x = 195 - 2x

Solution: 7 weeks

Step-by-step explanation:

x is going to stand for the number of weeks

Nick:

160 + 3x

Adam:

195 - 2x

Equation: 160 + 3x = 195 - 2x

Solution: 7

They would weigh 181 pounds

The equation to find when Nick and Adam will weigh the same amount is

160 + 3w = 195 - 2w

It will take 7 weeks for Nick and Adam to weigh the same amount.

After 7 weeks, Nick and Adam will both weigh 181 pounds.

An equation contains one or more terms with variables connected by an equal sign.

Example:

2x + 4y = 9 is an equation.

2x = 8 is an equation.

We have,

a.

Let w be the number of weeks, then the equation to find when Nick and Adam will weigh the same amount is:

160 + 3w = 195 - 2w

b.

To solve for w, we can simplify the equation:

160 + 3w = 195 - 2w

5w = 35

w = 7

c.

To find how much Nick and Adam will weigh after 7 weeks, we can plug w = 7 into either of the original equations:

Nick's weight = 160 + 3w = 160 + 3(7) = 181 pounds

Adam's weight = 195 - 2w = 195 - 2(7) = 181 pounds

Thus,
The equation to find when Nick and Adam will weigh the same amount is

160 + 3w = 195 - 2w

It will take 7 weeks for Nick and Adam to weigh the same amount.

After 7 weeks, Nick and Adam will both weigh 181 pounds.

Answer:

232 miles had travelled when Houa fell asleep.

Step-by-step explanation:

1. .29 x 800 = 232

If the total length of the trip was 800 miles then 232 miles had they travelled when Houa fell asleep.

percentage, a relative value indicating hundredth parts of any quantity.

Given that Houa's family took a road trip to the Grand Canyon.

Houa fell asleep 29% of the way through the trip.

If the total length of the trip was 800 mile we need to find the number of miles they travelled when Houa fell asleep.

29% can be converted to decimal by dividing with 100

29/100=0.29

Now multiply 0.29 with 800

0.29×800

232 miles

Hence, 232 miles had they travelled when Houa fell asleep.
