ANSWER

16\pi \: sq.in

EXPLANATION

The area of a sector is calculated using the formula,

Area =  \frac{arc \: measure}{360 \degree}  \times \pi {r}^{2}

The arc measure is given as 45°

The radius of the circle is 8 inches.

We substitute to obtain,

Area =  \frac{45 \degree}{360 \degree}  \times \pi  \times {8}^{2}

Area =  \frac{1}{4}  \times 64\pi  = 16\pi

How do you solve Y=x+1 x+2y=14 in substitution?
AleksAgata [21]

Answer:

(4, 5 )

Step-by-step explanation:

Given the 2 equations

y = x + 1 → (1)

x + 2y = 14 → (2)

Substitute y = x + 1 into (2)

x + 2(x + 1) = 14 ← distribute and simplify left side

x + 2x + 2 = 14

3x + 2 = 14 ( subtract 2 from both sides )

3x = 12 ( divide both sides by 3 )

x = 4

Substitute x = 4 into (1) for corresponding value of y

y = 4 + 1 = 5

Solution is (4, 5 )

Help please I’m confused
kipiarov [429]

Answer:

h = 5.4

Step-by-step explanation:

Basically these are 2 similar triangles. That means:

Corresponding sides are proportional.

We can set up a ratio of each triangle separately and equate, cross multiply and solve for "h".

h corresponds to 2.4

2.9 corresponds to 1.3

Setting up the ratio and solving for h:

\frac{h}{2.4}=\frac{2.9}{1.3}\\1.3h=2.4*2.9\\1.3h=6.96\\h=\frac{6.96}{1.3}\\h=5.35

Rounded to 1 decimal place,

h = 5.4

BRAINLIEST!!! I need help ASAP how do I find the percent change from 1960 to 2000
SVEN [57.7K]

Answer:

percentage change  from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

                                 = 44 %  

Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

                                                                 = 230.55%

 percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

                                               = 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

                                             = -6.667%                                              

Step-by-step explanation:

Item : 1960      1970          1980           1990             2000

gallon: $0.25  $0.36        $1.19    $1.35                 $1.26

change : 0.36 - 0.25 = 0.11

percentage change  from 1960 to 1970 =( 0.11 ÷0.25 ) × 100

                                 = 44 %

 Percentage change from 1970 to 1980 =( 0.83 ÷ 0.36) × 100

                                                                 = 230.55%

 percentage change from 1980 to 1990 = ( 0.16 ÷ 1.19) × 100

                                               = 13.44%

percentage change from 1990 to 2000 = (- 0.09 ÷ 1.35) × 100

                                             = -6.667%
