Answer:
7,12.2
Step-by-step explanation:
100+49=149
√149≈12.2
x^2+49=100
x^2=51
=7
Answer:
x = 816 kilometers per hour.
Step-by-step explanation:
Given the following data;
Distance traveled by Kirk = 450km
Distance traveled by Thor = 408 km
Let the average driving speed of Thor be x.
Translating the word problem into an algebraic equation;
k = x + 6
We know that the time taken to cover a distance by an object with speed is given by the formula;
Time = distance/speed
Substituting into the equation, we have;
408/x = 405/x + 6
Cross-multiplying, we have;
408*(x + 6) = 405*x
408x + 2448 = 405x
408x - 405x = 2448
3x = 2448
x = 2448/3
x = 816 kilometers per hour.
Answer:
the answer is 73.5
Step-by-step explanation:
to find the are of the box you have to do the mathematical equation of LxWxH (lengthxwidthxheight) in this case L=6, W=3.5, and H=3.5 so your equation would be 6x3.5x3.5 = 73.5
I believe the answer should be 8n - 4.
