Answer:

8 inches

Step-by-step explanation:

Assuming the figure is a circle

A = pi r^2

Given the area is 64 pi

64 pi = pi r^2

Divide each side by pi

64 pi /pi = r^2 pi/pi

64 = r^2

Take the square root of each side

sqrt(64) = sqrt(r^2)

8 = r

The radius is 8 inches

Which expression is equivalent to 30 (1/2 x - 2) + 40(3/4 y-4)
Xelga [282]

Answer:

Step-by-step explanation:

Start by removing the brackets.

Left Brackets

30(1/2 x - 2)

30*1/2 x - 30*2

15x - 60

Right Bracket

40(3/4 y - 4)

40*3/4 y - 4*40

10*3 y - 160

30y - 160

Now put these 2 results together.

15x - 60 + 30y - 160     Combine the like terms.

15x + 30y - 220            That's one answer Others are possible.

5(3x + 6y - 44)

Evaluate cos0 if sin0= sqrt(5)/3<br><br> a. 9/5<br> b. 2/3<br> c. 5/9<br> d. 3/2
Evgesh-ka [11]

Solution given:

\sin( \alpha )  =   \frac{\sqrt{5} }{3}

so

P=√5

h=3

b=\sqrt{3 {}^{2} -  \sqrt{5}  {}^{2}  }

b=2

so

\cos( \alpha )  =  \frac{b}{h}  =  \frac{2}{3}

Note

\alpha  = 0

<u>b</u><u>:</u><u>⅔</u>

Can someone help me with this please!~

Note that sum of triangle interior angles is 180. So,

(12x+12)+15+(3x+18)=180

15x+45=180

15x=135

x=9

Since A=12x+12=12.9+12=120

And C=3x+18=3.9+18=45
