Hi there! :)

$\large\boxed{A = 120^{o}}$

Find the central angle using a ratio in regards to angle and circumference.

The radius is 27 units, so use the following equation to calculate circumference:

C = 2rπ

Therefore:

C = 2(27)π = 54π

Since we have the total circumference, we can write the following proportion:

$\frac{x}{360} = \frac{18\pi}{54\pi}$

Cross multiply:

54πx = 6480π

Divide both sides by 54π to isolate for x:

x = 120°

Ivan biked 1 whole 2/3 on Monday, 2 wholes 1/3 hours on Tuesday, and 2 wholes 2/3 on Wednesday. What is the total number of hour

GenaCL600 [577]

$1 \frac{2}{3} + 2 \frac{1}{3} + 2 \frac{2}{3} =$

$\frac{3*1+2}{3} + \frac{3*2+1}{3} + \frac{3*2+2}{3} =$

$\frac{3+2}{3} + \frac{6+1}{3} + \frac{6+2}{3} =$

$\frac{5}{3} + \frac{7}{3} + \frac{8}{3} =$

$= \frac{20}{3} h$

In hours:

20 |_3
(2)....6hs
x60'
------
120' |_3
(0)....40'

Answer:
6hs40min

or

 $\frac{20}{3} hs = \frac{20}{3} *60' = \frac{1200}{3} = 400'$

400' = 6*60' = 360' + 40' = 400' (True)
Until

6hs40min

What is the value of b in the equation below? 9^-8 x 9^-2 = a^b -10 -6 9 16

lys-0071 [83]

Answer:

-10

Step-by-step explanation:

9^-8 x 9^-2 = a^b

We know that x^y * x^z = x^(y+z)

9^-8 x 9^-2 = 9^(-8+-2) = 9^(-10)

a= 9

b = -10

What is the surface area of the pyramid

Shalnov [3]

Answer:

S= 36.76

Step-by-step explanation:

S = area of base +(base of perimeter*Slant height)*1/2

S = 4*4+((4+4+4)/2)*3.46

S = 16+((12/2)*3.46)

S = 16+6*3.46

S = 16 + 20.76

S = 36.76 cm^2
