1. A stereo speaker in the shape of a triangular pyramid has a height of 6 inches. The area of the base of the speaker is 11 square inches.
F 22 in.3

G
198 in.3

H
66 in.3

J
33 in.3

2. What is the solution to this equation?
2x + 10 = 28
plz help :(

Answers

Answer 1
okay for number 1, even though there isn’t a question to answer, my best guess would be H, 66 in^3.

i multiplied the height (6) by the base (11) to get the 66.

———

for number 2, here’s what you should do.
2x + 10 = 28
- 10 -10
(subtract 10 from both sides of the equal sign)

you should get..
2x = 18
divide by 2 to get the x by itself..
x=9

and there u go! lmk if i helped u out babe

Answers

Answer: D

Step-by-step explanation:

To dilate by a scale factor of 5, multiply the x and y values of the points by 5

A(0,10) then A' would be (0,50)

Since 0 * 5 = 0 and 10 * 5 = 50

B(8,6) then B'(8*5,6*5) or (40,30)

C(4,2) then C'(4*5,2*5) or (20,10)

Find [tex]\sqrt[3]{27}[/tex]

Answers

Answer:

0.11

Step-by-step explanation:

your answer would be 0.11 I think.

Actually it would be 3. The question above is asking for the cubed root of 27. So in order to find this you have to figure out what multiplied by itself 3 times would equal 27. And 3 times 3 times 3 is the only option. 3 times 3 is 9 and 9 times 3 is 27. Not sure how the other person got .11 but this is the correct answer.

A circle of center (-3 , -2) passes through the points (0 , -6) and (a , 0). Find a?

Answers

Answer:

-4.5

Step-by-step explanation:

Answer:

[tex] a=1.58, \: \: a =-7.58[/tex]

Step-by-step explanation:

Since, circle of center (-3 , -2) is passing through the points (0 , -6) and (a , 0).

Therefore, points (0 , -6) and (a , 0) will be equidistant from the center of the circle (-3 , -2).

Hence,

Distance between (0 , -6) and (-3 , -2) = Distance between (a , 0) and (-3 , -2).

[tex] [0-(-3)]^2 + [-6-(-2)]^2=[a-(-3)]^2 + [0-(-2)]^2[/tex]

[tex] [0+3]^2 + [-6+2]^2=[a+3]^2 + [0+2]^2[/tex]

[tex] [3]^2 + [-4]^2=[a+3]^2 + [2]^2[/tex]
