a=1/2pa, solve for p
NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!

Answers

Answer:

A = (1/2)Pa = Pa/2

 

You can multiply both sides by 2 to eliminate the fraction on the right side:

 

2A = 2(Pa/2) = Pa

 

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

 

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

 

Rewriting:

 

P = 2A/a

 

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

It says “If 4 apples cost $1.00, what would be the cost of 10 apples?” -

Answers

Answer:$8.50

Step-by-step explanation: If 4 apples are $1.00 that means that one apple would be 25¢. 10 apples would mean $8.00 and since 2 apples are left that would be 50¢. Hence, the answer would be $8.50

It might be 2 dollars and 50 cents because since every apple is 25 cents and if you buy 8 apples it would be 2 dollars and another 2 apples will be 50 cents but I’m not sure

Which two parallelograms have the same area?

Answers

Answer:

Idc

Step-by-step explanation:

I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!

Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.

Figure 1: 15×4=60 cm

Figure 2: 18×3=54 cm

Figure 3: 11×6=66 cm

Figure 4: 12×5=60 cm

As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.

The answer is figure 1 and 4

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.

0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.

Answers

Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

What is Percentage?

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

                                                       = j + 0.08j

                                                       = 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.
