50 feet cubed because the problem is essentially 5 times 4 times 2.5
Answer:
i cant see the question
Step-by-step explanation:
A is a function
To represent a function each value from the input (x ) can only map to exactly one value in the output (y)
In B
x = 3 → y = 10/ 30 ← 2 values of y
In C
x = - 5 → y = 2/ 3 ← 2 values of y
x = - 10 → y = 4/ 5 ← 2 values of y
In D
x = 20 → y = 25/ 35 ← 2 values of y
A is the only table where each value of x maps to exactly one value in y
1 ——> given
2 —-> vertical angles are equal.
3 —> substitution
4 ——> if lines are || , corresponding angles are equal.
Ratio of children, adults and pensioners is 1 : 2 : 8/3 = 3 : 6 : 8.
Let, 3x is number of children.
So, 6x is number of adults and 8x is number of pensioners.
Now,
3x + 6x + 8x = 85
17x = 85
x = 5
Therefore, number of pensioners are 8×5 = 40.
Hence, this is the required solution.
