A B and D
Step-by-step explanation:
Answer:
Step-by-step explanation:
If A is in between Y and Z, then;
YA+AZ = YZ
Given.
YA = 14x,
AZ = 10x and
YZ = 12x + 48
Substitute into the formula
14x+10x = 12x+48
Find x;
24x = 12x+48
24x-12x = 48
12x = 48
x = 48/12
x = 4
Get AZ
AZ = 10x
AZ =10(4)
AZ = 40
Answer:140ft2
Step-by-step explanation: area= base times height
Area=14ft . 10ft
Area=140ft2
Answer:
The height of the pyramid is 5m
Step-by-step explanation:
To calculate the heigth of a pyramid we have to use the following formula:
v = volume = 70 m³
w = width = 6 m
l = length = 7 m
h = height
v = (w * l * h) / 3
we replace the values that we know
70m³ = (6m * 7m * h) / 3
70m³ * 3 = 42m² * h
210m³ / 42m² = h
5m = h
The height of the pyramid is 5m
