Find the height of the giraffe in the diagram. Show your work below.

dlinn [17]

The distance from the person to the mirror is 5 ft. The distance from the mirror to the giraffe is 15 ft.

15/5 = 3

Multiply the height of the person by 3:

5 ft = 60 inches 60+3 = 63 inches

63 x 3 = 189 inches

189/12 = 15.75 ft = 15 feet 9 inches

The giraffe is 15 ft 9 inches tall

Rewrite! Write an new and equivalent equation that is easier to solve

Marysya12 [62]

$\huge\underline{\red{A}\blue{n}\pink{s}\purple{w}\orange{e}\green{r} -}$

Given - an equation in a standard form

To do - simplify the equation so as to obtain an easier one

Since the equation provided isn't in it's general form , let's first convert it ~

General form of a Linear equation -

$\bold{ax + b = 0}$

The equation after getting converted will be as follows ~

$- 7 + ( \frac{4x + 2}{2} ) = 8 \\ \\ \implies \: \frac{ - 14 + 4x + 2}{2} = 8 \\ \\ \implies \: - 14 + 4x + 2 = 16 \\ \\ \implies \: 4x = 16 + 14 - 2 \\ \\ \implies \: 4x = 28 \\ \\\bold{ General \: form \: \dashrightarrow \: 4x - 28 = 0}$

hope helpful ~

The diameter of an insect cell is 1.7 × 10–11 meter. Ariel wants to find the length of the radius of the cell. If she performs t

Juli2301 [7.4K]

Answer:

8.5E-12

Step-by-step explanation:

According to the Question,

Given That, The diameter of an insect cell is 1.7 × 10^-11 meters.

Ariel wants to find the length of the radius of the cell. Radius Is Half of the Diameter.

Thus, R = D/2 ⇒ (1.7*10^-11)/2 = 0.85× 10^-11
If she performs the calculations on her calculator is 8.5E-12.
