Answer:

Alix does. See below.

Step-by-step explanation:

Givens

Jenny

b1 = 90 cm
b2 = 80 cm
height = 23 cm

Alex

b1 = 90 cm
b2 = 70 cm
height = 27 cm

Formula

For both territories the answer is based on the formula

Area = (b1 + b2)*h/2

Solution

Jenny

Area = (90 + 80)23/2
Area = 170 * 23 / 2
Area = 85 * 23
Area = 1955 units.

Alex

Area = (70 + 90)*27/2
Area = 160*27 / 2
Area = 80* 27
Area = 2160

Alix does by 205 cm

What should be subtracted from 13/(-56) to get 11/28

zloy xaker [14]

Answer:

-5/8

Step-by-step explanation:

13/ -56 -x = 11/28

Add 13/56 to each side

13/ -56 + 13/56 -x = 11/28+ 13/56

-x = 11/28 + 13/56

Get a common denominator

-x = 11/28 *2/2 +13/56

-x = 22/56 + 13/56

-x = 35/56

Divide top and bottom by 7

-x = 5/8

Multiply both side by -1

x = -5/8

Which explanation can be used to derive the formula for the circumference of a circle?

Gelneren [198K]

Answer: The answer is the first explanation.

Step-by-step explanation: We are given five different options and we are to select which explanation is correct to derive the formula for a circumference of a circle.

Let 'C' be the circumference and 'd' be the diameter of a circle. Now, we will write the ratio of the circumference to the diameter as

$\dfrac{\textup{C}}{\textup{d}}.$

Also, we know that

$\dfrac{\textup{C}}{\textup{d}}=\pi.$

And diameter of a circle is twice the radius, so

$d=2r.$

Therefore,

$\dfrac{\textup{C}}{2\textup{r}}=\pi\\\\\Rightarrow \textup{C}=2\pi \textup{r}.$

This is the formula for the circumference of a circle. Since this explanation matches exactly with the first option, so the correct option is

(a). Find the relationship between the circumference and the diameter by dividing the length of the circumference and length of the diameter. Use this quotient to set up an equation to showing the ratio of the circumference over the diameter equals to π . Then rearrange the equation to solve for the circumference. Substitute 2 times the radius for the diameter.
