Step-by-step explanation:
a) r=d/t ( same as formula of speed)
b) r= 665280/3=221760 feet/hr
c) distance in miles = 665280/5280= 126
so r=126/3 = 42 miles/hr
d) i think using miles makes more sense cz using feet will result in greater number of values so there is a greater chance of human error
Answer:
d = 7.2
Step-by-step explanation:
Step 1: Write out equation
d/1.2 = 6
Step 2: Multiply both sides by 1.2
d = 7.2
Answer:
it is 7.5 rate
Step-by-step explanation:
I used a calculator to get the answer and it is correct.
Answer:To calculate the volume of a triangular prism, measure the width and height of a triangular base, then multiply the base by the height by 1/2 to determine the triangle's area. Next, measure the height of the triangular prism and multiply this by the triangle's area to get the volume. I hope that helped a little
Step-by-step explanation:
Answer:
a). 8(x + a)
b). 8(h + 2x)
Step-by-step explanation:
a). Given function is, f(x) = 8x²
For x = a,
f(a) = 8a²
Now substitute these values in the expression,
= 
= 
= 
= 8(x + a)
b).
= 
= 
= 
= (8h + 16x)
= 8(h + 2x)
