Answer:
15
Step-by-step explanation:
Cross multiply to get 25x = 375
Divide each side by 25 to get x = 15
Answer:
19.2
Step-by-step explanation:
<u>1st Case:</u>
4 and 5 are legs of the right triangle.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+5^2=x^2
16+25=x^2
41=x^2
x=√41
√41 is about 6.4
x=6.4
<u>2nd Case</u>
5 is the hypotenuse of the right triangle and 4 is the legs.
Using the pythagorean therom: a^2+b^2=c^2
We can say that 4^2+x^2=5^2
16+x^2=25
x^2=9
x=3
<u>Final Step</u>
We need to multiply the two possible lengths for x. So for case 1 the length of x was 6.4 and for case two the length was 3. 6.4*3=19.2
Anwser: <u>19.2</u>
1.86·10 to the 13th power
The answer is D y=|x| + 4
First, you need to put both equations in slope intercept form
Kyle: y=3x+50, because he runs 3 meters/second and he gets a 50 meter head start
Michael: y=4x
I think the answer would be 50 seconds
hope this helps
