Answer
Find out the what is the surface area of the pyramid .
To proof
Formula
Surface area of a square pyramid
Where a is the base edge and h be the height .
As given
A square pyramid has a base with side lengths each measuring 40 inches. The pyramid is 21 inches tall, with a slant height of 29 inches.
i.e Base edge = 40 inches
Height = 21 inches
Put values in the above formula
solving
= 1600 + 80 × 29
= 3920 inches²
Therefore the surface area of the pyramid is 3,920 inches²
Hence proved
What I did to solve this is finding the equation of the line using slope intercept form y is the cost of the ride which increases as you increase mileage or move along the X axis. My points are (2, 5.25) and (5,10.5)
<span>y=mx+b </span>
<span>m=y2-y1/x2-x1 </span>
<span>m=(10.5-5.25)/(5-2) </span>
<span>m=5.25/3=1.75 or 7/4 </span>
<span>y=7/4x+b enter one point for the values of x and y to find b </span>
<span>10.5=(1.75X5) + b </span>
<span>10.5=8.75 + b </span>
<span>b=1.75 </span>
<span>The equation of the line is y=7/4x+1.75 (I also double checked using the second point) </span>
<span>Then all you have to do is enter the mileage 3.8 for the value of X and solve for y </span>
<span>y=(7/4 X 3.8) + 1.75 </span>
<span>y=6.65+1.75 </span>
<span>y=8.4 The cab ride for the 3.8mile trip is $8.4
I hope this helps</span>
The product of 4 and 7 would be 28!
When someone says the product of x means they are looking to multiply!
If d = rt, then you plug in. D = 6(4) = 24.
24 miles. If you need a picture of this work, let me know.
Answer:
It is true.
Step-by-step explanation:
4*8 = 32, which is divisible by 4.
222*608 = 134 976, which is divisible by 4.
