The price of an item yesterday was $120.Today the price fell to $78 find the percentage decrease

Answers

Answer 1

Answer:

The answer is $120.00-$78.00=$42.00

Answer 2

Answer:

Final answer:

To calculate the percentage decrease, subtract the final price from the initial price, divide this difference by the initial price, and multiply by 100.

Explanation:

The percentage decrease in price can be calculated by finding the difference between the initial price and the final price, dividing it by the initial price, and then multiplying by 100. In this case, the initial price was $120 and the final price was $78. So, the difference is $120 - $78 = $42.

Next, divide the difference by the initial price: $42 / $120 = 0.35.

Multiply the result by 100 to find the percentage decrease: 0.35 * 100 = 35%.

Hi! Since the cake is split into eight slices, this is a simple equation.

1/2 of the cake is four slices. 8/4=2 Shontavia may have a stomach ache!

1/8 also means one slice.

So, 1/8+4/8+2/8=7/8. Only one slice is left! The correct answer is F.

A cylinder has a surface area of 1850 square meters and a radius of 9 meters. Estimate the volume of the cylinder to the nearest whole number. How????

Answers

in order to find the volume you need the height.

Surface area = π r² + base x height or width x length
1850 = 3.14 × 9² + radius × 2 x π x height
1850 = 254.34 + 9 × 2 × 3.14 × height
1850 = 310.86 × height

To find the height you have to divide the surface area by the part I bolded

Height = 1850 ÷ 310.56
Height ≈ 6

Volume of a cylinder = πr²×height
= 3.14 × 9 × 9 × 6
Volume =1526.04

Nearest whole number would be 1526

in one day a movie store rented out 20 comedies. if the ratio of comedies rented to action movies rented was 4:3, how many action movie were rented ?

Answers

One way to solve is to set up a proportion. If the ratio of comedies to action is 4:3 (also can be written as the fraction 4/3) then you can set 4/3 equal to 20/x.

4/3 = 20/x

then cross multiply.

4·x = 3·20

4x = 60 Then divide both sides by 4

x= 15

the answer is 15 action movies were rented

Lena can run 4 miles in 30 minutes. Rachel can run 7 milesin 56 minutes. What proportion could you write to see if they are
running at the same rate?

Answers

We want to create a proportion with minutes over miles for each person. The proportion for this problem is shown below.

30 minutes / 4 miles = 56 minutes / 7 miles

To find out if these people are running at the same rate, we can cross-multiply.

224 = 210

Because 224 and 210 are not equivalent, the people are not running at the same rate.

Hope this helps!! :)
