Answer:
2143.6 ft³
Step-by-step explanation:
We use formula number 2 to get the volume. V=4\3πr³
4\3 x 3.14 x 8³ = 2143.573333
Rounded of to the nearest tenth = 2143.6 ft³

Answer:
23
Step-by-step explanation:
Given: Given that a citizen have 97 silver coins.
To find : Here we need to find that how many bronze coins would it take to equal this amount.
Solution: We know, 1 silver coin=10 bronze coin
So, 97 silver coin=10×97 bronze coin
=970 bronze coin
Therefore, 970 bronze coins would it take to equal this amount.
Answer:
Step-by-step explanation:
-8x + 2y = -4 12x - 3y = 4
y = -3x - 2 y = 4x
sub sub
-8x + 2(-3x - 2) = -4 12x - 3(4x) = 4
-8x - 6x - 4 = -4 12x - 12x = 4
-14x = -4 + 4 0 = 4
-14x = 0 NO SOLUTION
x = 0 ========================
y = -3x - 2 -3 + 2y = 5
y = -3(0) - 2 -4x + y = 10...y = 4x + 10
y = -2 sub
solution is : (0,-2) -3 + 2(4x + 10) = 5
================ -3 + 8x + 20 = 5
3x + 2y = 11 8x + 17 = 5
x + 2y = 9...x = 9 - 2y 8x = 5 - 17
sub 8x = - 12
3(9 - 2y) + 2y = 11 x = -12/8
27 - 6y + 2y = 11 x = -3/2
-4y = 11 - 27
-4y = -16 y = 4x + 10
y = -16/-4 y = 4(-3/2) + 10
y = 4 y = -12/2 + 10
y = -6 + 10
x = 9 - 2y y = 4
x - 9 - 2(4) solution (-3/2,4)
x = 9 - 8
x = 1
solution : (1,4)
Answer:
Step-by-step explanation:
The photo for the question is not given. I have searched and attached it.
From the attached photo, the inequality is
-2x/3 + 9 > 7
By simplifying, subtract 9 from both sides of the inequality. It becomes
-2x/3 + 9 - 9 > 7 - 9
- 2x/3 > - 2
Multiplying both sides of the inequality by - 3/2, the inequality symbol would change due to the negative sign. It becomes
- 2x/3 × 3/2 < - 2 × - 3/2
x < 3
Therefore,
Yuto is correct because he isolated the variable correctly and reversed the inequality symbol.
