Mathematics
1 answer:
Dima020 [189]3 years ago
4 0

Answer:

radius=3

Step-by-step explanation:

volumes of a cone = 1/3πr²h

12π = 1/3× π × r² × 4

37.7 = 12.6r²/3

cross multiply

37.7×3=12.6r²

113.1=12.6r²

make r² subject of the formula

r²=113.1÷12.6

r²=8.976

r=√8.976

r=2.996

r=3.0 (to the nearest tenth)

What is the solution of √-4x=100?<br> A) x = –2500<br> B) x = –50<br> C) x = –2.5<br> D) no solution
yawa3891 [41]
First we raise both members of the equality to the square:
 (√-4x) ^ 2 = (100) ^ 2
 Then, we solve:
 -4x = 10000
 We cleared x in the last instance
 x = 10000 / (- 4)
 x = -2500
 answer:
 the solution of √-4x=100 is 
 A) x = –2500

Nadya [2.5K]
First figure out his total bill by adding up what he buys.

\sf 78.04+24.81+17.96=\$120.81

Now subtract the discount of $20 since his purchase was above $100:

\sf 120.81-20=\boxed{\sf\$100.81}

What value of x makes the following equation true?<br> 15+3x=3(2−2x)
Alinara [238K]

Answer:

\boxed {x = -1}

Step-by-step explanation:

Solve for the value of x:

15 + 3x = 3(2 - 2x)

-Use <u>Distributive Property</u>:

15 + 3x = 3(2 - 2x)

15 + 3x = 6 - 6x

-Take 6x and add it to 3x:

15 + 3x + 6x = 6 + 6x - 6x

15 + 9x = 6

-Subtract both sides by 15:

15 - 15 + 9x = 6 - 15

9x = -9

-Divide both sides by 9:

\frac{9x}{9} = \frac{-9}{9}

\boxed {x = -1}

Therefore, the value of x is -1.
