Answer:
<h3>3cm</h3>
Step-by-step explanation:
Area of a triangle = 1/2 * base * height
Given
Area = 7 7/8cm²
Base = 5 1/4 cm
Required
Height of the triangle
Substitute;
7 7/8 = 1/2 * 5 1/4 * Height
63/8 = 1/2 * 21/4 * h
63/8 = 21H/8
63 = 21H
H = 63/21
H = 3cm
Hence the length of h is 3cm
Answer:
310 yards and 1,240 yards
Step-by-step explanation:
Let first football player rushed x yards.
One football player rushed 4 times as many yards as the other, then the second player rushed 4x yars.
In total, they rushed
yards.
Last season two running backs on the Steelers football team rushed or a combined total of 1,550 yards.
Hence,
Answer:
(0,-5)
(4,-2)
(-16,-17)
Step-by-step explanation:
Any (x,y) point that satisfies the equation is a solution. First simplify the equation.
3x - 4y - 8 = 12
3x - 4y = 20
Substitute x = 0 and y = -5.
The equation becomes 3(0) -4(-5) = 20.
0 + 20 = 20
This is a solution.
The following points also work and are solutions.
(4, -2) and (-16,-17)
Answer:
Probability (not green) = 21 / 29
Step-by-step explanation:
Given:
Number of red marble = 10
Number of green marble = 8
Number of blue marble = 5
Number of white marble = 6
Find:
Probability (not green)
Computation:
Total marble = 10 + 8 + 5 + 6
Total marble = 29
Probability (not green) = 1 - (Probability of green marble))
Probability (not green) = 1 - (8 / 29)
Probability (not green) = 21 / 29
