Mr. Jamison will stain the deck in his backyard, the deck has an area of 752.4 sqaure feet. If the deck is 33 feet long how wide is it? Justify your procedure.

Answers

Answer 1

answer:The width of the deck is 22.8 feet.

Step-by-step explanation:

Since we have given that

Area of the deck = 752.4 square feet

Length of deck = 33 feet

Let width of deck be 'x'.

Since Deck is in the shape of rectangle.

As we know the formula for "Area of rectangle ":

\begin{gathered}Area=Length\times width\\\\752.4=33\times x\\\\\dfrac{752.4}{33}=x\\\\22.8=x\end{gathered}

Area=Length×width

752.4=33×x

752.4

22.8=x

Hence, the width of the deck is 22.8 feet.

Step-by-step explanation:

For a all you have to do is multiply by 3 so the answer would be -15

For b all you have to do is subtract 12 then divide by -1 so the answer would be -0.5

for c all you have to do is divide by -10 so the answer would be -0.1/-10 or 0.1/10

3x - 5y = -35
please solve and show your work

Answers

You use the formula y=mx+b, therefore you have to isolate the y
First you subtract 3x to both sides.
3x - 5y = -35
-3x -3x
Then it would be
-5y = -3x -35
Then you divide -5 on both sides to isolate the y
-5y = -3x -35
/-5 /-5 /-5
Two negatives cancel out and make a positive so it would be
Y = 3/5x + 7

The selling price of an item is $390. It is marked down by 10%, but this sale price is still marked up from the cost of $270. Find the markup from cost to sale price.

Answers

Answer:

find the actual discount, multiply the discount rate by the original amount 'x'. To find the sale price, subtract the actual discount from the original amount 'x' and equate this to given sale price. Solve the equation and find the original amount 'x'.

Step-by-step explanation:

Sale Price = $11.34 (answer). This means the cost of the item to you is $11.34. You will pay $11.34 for a item with original price of $12.60 when discounted 10%. In this example, if you buy an item at $12.60 with 10% discount, you will pay 12.60 - 1.26 = 11.34 dollars.

The markup from cost to sale price is 81 dollars.

What is the cost price?

Cost price, for instance, equals selling price plus profit ( when selling price and profit is given )

Cost is equal to Selling price plus Loss ( when selling price and loss is given )

The Cost price = 100 Selling Price + 100 + Profit

where the Selling Price and Profit Percentage are supplied.

The selling price of item = $390

cost = $270

10% × $390 = $39

Now subtract 39 from 390

390 - 39

351

Now subtract 270 from 351

351- 270

$81 is markup price .

Cassie wants to buy a pair of shoes for $26.50 and a shirt for $9.50. If the sales tax rate is 8.25%, what will be the amount of sales tax on Cassie’s purchase?
$3.13
$2.97
$3.06
$2.89

Answers

The amount of sales tax is $2.97.

The tax for the shoes: 26.50*0.0825=2.18625

The tax for the shirt: 9.5*0.0825=0.78375

2.18625+0.78375=2.97

pls mark brainliest:))

Answer:

B. 2.97

Step-by-step explanation:

First, add 26.5 plus 9.5 to get the total of the purchase without tax. Then, create a proportion (8.25/100= x/36). multiply 8.25 by 36, and divide the product by 100 to get 2.97. Hope this helps!
