Answer:
4 hours
Step-by-step explanation:
cross multiply
Answer:
Sorry im not good at diameters
Step-by-step explanation:
hopefully this helps. since its divided by 2 x would be 4 and y would be 2.5
Answer:
{42,56,70}
Step-by-step explanation:
a^2 + b^2 = c^2
42^2 = 1764
56^2 = 3136
70^2 = 4900
3136 + 1734 = 4900
Hello!
Question 1
We first have to convert everything to yards since the concrete is charged by the cubic yards
15 feet = 5 yards
15 feet = 5 yards
3 inches = 0.08333
Multiply these to find the volume
5 * 5 * 0.08333 = 2.08325
Multiply this by the cost
2.08325 * 46 = 95.83
The answer is C) $95.83
------------------------------------------------------------------------------------------------------
Question 2
You have to find the volume of the first pyramid
The equation we use is

V is volume
l is length
w is width
h is height
Put in the values we know

Multiply

Divide
V = 2389.3333
Now we use this to find the side length of the second pyramid

Multiply both sides by 3
<span>7167.999 = lw * 112
</span>
Divide both sides by 112
63.9999 = lw
Since it is a square pyramid we know that sides are equal
63.999 = l^2
Take the square root of both sides
8 = l
The answer is B) 8in
Hope this helps!
