Plug in what you are given from the table into the equation to find the missing value

1. 2x - 0 = 8
2x = 8
x = 4

2. 2x - -8 = 8
2x + 8 = 8
2x = 0
x = 0

3. 2(5) - y = 8
10 - y = 8
- y = -2
y = 2

4. 2(-3) - y = 8
-6 - y = 8
- y = 14
y = -14

Find the areas of the sectors formed by ∠DFE. Round your answers to the nearest hundredth.

bija089 [108]

Answer:

Area of the sector in red = 177.87 cm²

Area of the sector in blue = 437. cm²

Step-by-step explanation:

Area of the sector = $\frac{\theta}{360}(\pi )(r)^2$

Area of the sector shaded in blue = $\frac{256}{360}(\pi )(14)^2$

= 437.87 cm²

Central angle formed by sector shaded in red = 360 - 256 = 104°

Area of the sector shaded in red = $\frac{104}{360}(\pi )(14)^2$

= 177.884

≈ 177.88 cm²

Therefore, area of the sector shaded in red = 177.87 cm² and area of the sector in blue = 437.88 cm²

Answer:

The difference of 15 and 4 times a number

4a - 15

I want to buy 4 tickets to go to Disney World. They are currently on sale for with a 12% discount.

100% representate the original cost of tikets,

100% = 100/100 = 1

12% discont:

12% = 12/100 = 0.12

1 - 0.12 = 0.88

0.88

then the expressión is:

4*0,88d

=3.52 d

d = original cost of each ticket
