Answer:

The answer to your question is Area = 50.27 m²

Step-by-step explanation:

Data

Area = ?

Diameter = 8 m

π = 3.1416

Formula

Area = πr²

Process

1.- Find the length of the radius

radius = diameter/2

- Substitution

radius = 8/2

- Result

radius = 4 m

2.- Find the area of the circle

Area = (3.1416) (4)²

Simplification and result

Area = (3.1416) (16)

Area = 50.27 m²

ΔEFG is located at E (0, 0), F (−7, 4), and G (0, 8). Which statement correctly classifies ΔEFG?

MariettaO [177]

Answer:

ΔEFG is an isosceles triangle.

Step-by-step explanation:

Given:

E (0, 0),

F (−7, 4),

G (0, 8)

ΔEFG

Solution:

Distance formula

Distance d = $\sqrt{(x_2-x_1)^2 +( y_2-y_1)^2$

Step 1: Finding the length of EF

By using distance formula,

$EF = \sqrt{(-7 - 0)^2 + (4-0)^2}$

$EF = \sqrt{(49) + (16)}$

$EF = \sqrt{(49) + (16)}\\EF = \sqrt{65}\\$

Step 2: Finding the length of FG

By using distance formula,

$FG = \sqrt{(0-(-7))^2+(8-4)^2}\\FG = \sqrt{(7)^2 +(4)^2}\\FG = \sqrt{49 +16}\\FG = \sqrt{65}$

Step 2: Finding the length of GE

$GE= \sqrt{(0-0)^2 + (0-8)^2}\\\\GE =\sqrt{(-8)^2}\\GE = \sqrt{64}\\GE = 8$

Thus we could see that the sides EF = FG

So it is a isosceles triangle.

She spent 1/6 of it on snacks and 1/3 of it on a new book. She saves the rest. What fraction of the money did she save?

Doss [256]

Answer:

Step-by-step explanation:

First step is that you need to have the same denominators so 1/3=2/6

If she spent 1/6 on snacks and 2/6 on a book which means she spent 3/6

so the fraction of what she saved is 3/6 or 1/2
