Answer:
75 m³
Step-by-step explanation:
From the question given, we obtained the following data:
For figure A:
Base length (Bₐ) = 2 m
Volume (Vₐ) = 30 m³
For figure B:
Base length (B₆) = 5m
Volume (V₆) =?
Since both shapes are similar, the volume of figure B can be obtained as follow:
Bₐ/B₆ = Vₐ/V₆
2/5 = 30/V₆
Cross multiply
2 × V₆ = 5 × 30
2 × V₆ = 150
Divide both side by 2
V₆ = 150 / 2
V₆ = 75 m³
Therefore, the volume of figure B is 75 m³

Answer:
The ordered pair is one of the solution to the system of equations. See below.
Step-by-step explanation:
To tell if the ordered pair is the solution to the system of equations or not, we can do by substituting the ordered pair in both equations.
(x, y) = (5,-6)
Substitute x = 5 and y = -6 in both equations.
<u>First</u><u> </u><u>Equation</u>
6x+3y=12
6(5)+3(-6)=12
30-18=12
12=12
<u>Second</u><u> </u><u>Equation</u>
4x+y=14
4(5)-6=14
20-6=14
14=14
Because both equations have same sides which mean that both equations are true for (5,-6). Therefore (5,-6) is part of the equations.
Answer:
x = -6
y = 8
Step-by-step explanation:
Using substitution method.
2x + y = -4 -----------(I)
y = - 4 - 2x -----------(II)
5x + 3y = -6 -------------------(III)
Substitute y = -4 -2x in equation (III)
5x + 3(-4-2x) = - 6
5x - 12 - 6x = -6
5x - 6x - 12 = -6
Combine like terms
-x - 12 = -6 {Add 12 to both sides}
-x = -6 + 12
-x = 6 {Multiply by (-1)}
x = -6
Substitute x = -6 in equation (II)
y = - 4 - 2*(-6)
= -4 + 12
y = 8
