Sector area can be found with the formula $A = \frac{\theta}{360} \pi r ^2$ where $\theta$ is the central angle.

r = 8m , $\theta$ = 135º

$A = \frac{135}{360} \pi (8)$ m^2

Arc length formula is $s = 2\pi r (\frac{\theta}{360} )\\$

$s = 2\pi (8)(\frac{135}{360} )\\$ m

2( 4x + 2) = 4x – 12(x - 1).

Tcecarenko [31]

Answer:

x=-1/2

Step-by-step explanation:

2(4x + 2) = 4x – 12(x - 1)

8x+4=4x-12x+12

8x+4=-8x+12

-4 -4

8x=-8x-8

+8x +8x

16x=-8

16x/16=-8/16

x=-1/2

Romashka [77]

Answer:

50,015

Step-by-step explanation:

The total of ratio units is 7+5+9 = 21. Of those at company A, that company donated 7, or 7/21 = 1/3 of the total. 1/3 × 150,045 = 50,015

An account earns simple interest.

sergiy2304 [10]

The formula for simple interest is given by

I=PRT

We are given P=$1500

R=4% or 0.04

T=5 years

plugging them in the equation I=PRT , we get

I =1500*0.04*5 = 300

so interest is $300

Amount =P+I

Amount =1500+300 =1800

Amount $1800
