Answer:
V ≈ 714 in³
Step-by-step explanation:
The volume of a triangular prism can be found using the formula:
V = Bh, where B = the area of the base and h = the height of the prism. Since the base is a triangle, you will need to use the formula for area of a triangle: A = bh.
In this figure, the base of the triangle = 23.25 and the height of the triangle is 10.25. So, the area = ()(23.35)(10.25) ≈ 119 in²
With the B = 119 and the height of the prism = 6:
V = 119(6) = 714 in³
Answer:
There are 36 boys in the class.
Step-by-step explanation:
This question is solved by a system of equations.
I am going to say that:
x is the number of boys
y is the number of girls.
There are 42 pupils in a class.
This means that .
Since we want x, we have that
12 of them are Malays while the rest are Chinese. 1/4 of the boys and 1/2 of the girls are Malay.
This means that:
Since
Multiplying everything by 4.
There are 36 boys in the class.
Answer:
A: -5, -1, 5, 6, 7
B: -12.4, -12.1, -2, 1/2, 12, 12 1/4, 12 1/2
Answer:
0.313
Step-by-step explanation:
The probability of getting one head is 1/2
The favourable outcomes are 5/8
Multiply: 1/2 × 5/8 = 5/16
Convert: 5 ÷ 16 = 0.3125
