A
The volume (V) of a pyramid is found using the formula
V =
× area of base × height(h)
area of base = 9² = 81 ← area of a square, hence
324 =
× 81 × h = 27h ( divide both sides by 27 )
h =
= 12 → A
Answer:
Step-by-step explanation:
n=1
1²-5=-4
2²-5=-1
3²-5=4
10²-5=95
Answer:
I think degree means the highest exponent, so wouldnt it be 8?
Answer:
t = 6.2/s miles/minute
Step-by-step explanation:
Average speed is defined as the rate of change in distance of a body. Mathematically; speed = Distance/Time
Given the distance of the runner in miles to be d = 6.2miles
Time taken = t
Average speed = s
To express t in terms of the average speed s and distance of 6.2miles, we will substitute the values into the formula;
s = D/t
Substituting D = 6.2miles into the formula;
s = 6.2/t
Cross multiply
St = 6.2
Divide both sides by 's'
st/s = 6.2/s
t = 6.2/s
Hence, the equation that could be used to determine the time, t, it takes to run 10,000 meters as a function of the average speed, s, of the runner where t is in minutes and s in miles per minute is t = 6.2/s miles/minute
