Answer: The distance around the lot is given by
Step-by-step explanation:
Since we have given that
Length of rectangular lot is given by
Width of rectangular lot is given by
We need to find the distance around the lot.
As we know the formula for "Perimeter of rectangle":
Hence, the distance around the lot is given by
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!

We can assume that the shape is a rectangular prism by the given dimensions
Volume of a rectangular prism
Volume = Area of Base × Height of prism
= Length × Width × Height of prism
Substitute!
168 = L × 7 × 3
168 = L × 21
Divide 21 on either sides to isolate L
= 
21 and 21 cancels out
8 = L
L = 8 yd
