What is the discount rate for a $120 camera that is on sale for $105?

In the figure to the right, AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3 /10 cm. Find the perimeter of the fig

pentagon [3]

Answer:

The perimeter of the figure = 9.5 cm

Step-by-step explanation:

Note: You probably missed to add the figure, but after a little research I found and am attaching the figure. I have answered your question based on the reference of that figure. But, I hope you would learn the concept so that you could solve any question based on this concept. So, please check the figure.

Solution:

The perimeter of the figure is the sum of all the sides of the given figure as shown in the attached figure.

So, here is the formula to calculate the perimeter.

Perimeter = AB + DE + BC + AE + BC

As AE + DC = 1 1/5 cm, AB = 1 3/4 cm, DE = 1 1/4 cm, and BC = 1 3/10 cm

Therefore,

Perimeter = 1 3/4 + 1 1/4 + 13/10 + 1 1/5 ∵ AE + BC = 1 1/5

= (130 + 110 + 52 + 88) / 40

= 380/40

= 9.5 cm

So, the perimeter of the figure is = 9.5 cm

Is the sum of the areas of two smaller squares equal to the area of a large square if the side lengths of the squares are 8 feet

Ivanshal [37]

No, the sum of the areas of two smaller squares is not equal to the

area of a large square

Step-by-step explanation:

To solve this problem let us do these steps

1. Find the area of the larger square

2. Find the area of the two smaller squares

3. Add the areas of the two smaller squares

4. Compare between the sum of the areas of the 2 smaller squares

and the area of the larger square

The area of a square is s²

The length of the side of the larger square is 8 feet

∵ s = 8 feet

∴ Area of the larger square = (8)² = 64 feet²

The lengths of the sides of the smaller squares are 5 feet and 3 feet

∵ s = 5 feet

∴ The area of one of the smaller square = (5)² = 25 feet²

∵ s = 3 feet

∴ The area of the other smaller square = (3)² = 9 feet²

The sum of the areas of the two smaller squares = 25 + 9 = 34 feet²

∵ The area of the larger square is 64 feet²

∵ The sum of the areas of the two smaller squares is 34 feet²

∵ 64 ≠ 34

∴ The sum of the areas of two smaller squares is not equal to the

area of a large square

No, the sum of the areas of two smaller squares is not equal to the

area of a large square

5. Abbey Road Motors pays a percent commission to its sales people. They are paid

ira [324]

Answer:

c(p) = {0.2 p ⇒ p < 1000

0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000

0.29 p - 140 ⇒ p > 2000}

Step-by-step explanation:

* Lets explain how to solve the problem

- The profit is represented by p

1. If the profit is under $1,000, the commission rate is 20%

∵ The profit is p < 1000

∵ 20% of p = $\frac{20}{100}*p$ = 0.2 p

∵ c(p) is the function of the commission

∴ c(p) = 0.2 p when p < 1000

2. If the profit is at least $1,000 and less than or equal to $2,000, the

commission rate is 20% of the first $1,000 and 24% of the remainder

of the profit

- At least means greater than or equal

∵ The profit 1000 ≤ p ≤ 2000

- The commission is divided into 20% of first $1000 and 24% of

the reminder

∵ 20% of 1000 = $\frac{20}{100}*1000$ = 200

∵ The remainder of the profit = p - 1000

∵ 24% of the remainder profit = $\frac{24}{100}*(p-1000)$

= 0.24(p - 1000) = 0.24 p - 240

∴ The total commission = 200 + 0.24 p - 240

∴ The total commission = 0.24 p - 40

∴ c(p) = 0.24 p - 40 when 1000 ≤ p ≤ 2000

3. If the profit is above $2,000, the rate is 20% of the first $1,000

of profit, 24% of the next $1,000 of profit, and 29% of the amount

of profit over $2,000

∵ The profit p > 2000

- The commission is divided into 20% of first $1000 and 24% of the

next $1,000 of profit, and 29% of the amount of profit over $2,000

∵ 20% of 1000 = $\frac{20}{100}*1000$ = 200

∵ 24% of 1000 = $\frac{24}{100}*1000$ = 240

- The amount of profit over $2,000 = p - 2000

∵ 29% of the amount of profit over $2,000 =

$\frac{29}{100}*(p-2000)$ = 0.29(p - 2000)

= 0.29 p - 580

∴ The total commission = 200 + 240 + 0.29 p - 580

∴ The total commission = 0.29 p - 140

∴ c(p) = 0.29 p - 140 when p > 2000

* The commission function is:

c(p) = {0.2 p ⇒ p < 1000

0.24 p - 40 ⇒ 1000 ≤ p ≤ 2000

0.29 p - 140 ⇒ p > 2000}
