Answer:
A. she made $1,694.92 weekly last year
B.she makes $1,847.49 weekly this year
C. she makes $152.57 more weekly this year than ast year.
Step-by-step explanation:
For acceleration use this formula: (v-u) /t
V is the final velocity
U is the intial velocity and t is time.
For speed u hav to calculate the the total distance and total time then use this formula:
Average speed=
Total distance / Total time
SOLUTION
From the image in the question, we can see that it is a right triangle problem.
And we can use the Pythagoras theorem to solve for the length of cable wire needed.
Pythagoras theorem states that:

![\begin{gathered} x^2=16+9 \\ x^2=25 \\ \text{Take the square roots of both sides:} \\ \sqrt[]{x^2}=\sqrt[]{25} \\ x=5ft \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20x%5E2%3D16%2B9%20%5C%5C%20x%5E2%3D25%20%5C%5C%20%5Ctext%7BTake%20the%20square%20roots%20of%20both%20sides%3A%7D%20%5C%5C%20%5Csqrt%5B%5D%7Bx%5E2%7D%3D%5Csqrt%5B%5D%7B25%7D%20%5C%5C%20x%3D5ft%20%5Cend%7Bgathered%7D)
Final Answer:
A cable of length 5 feet is needed.
Answer:
? = 54.
Step-by-step explanation:
According to the AA Theorem, the two triangles are similar.


7(? + 63) = 63 * 13
? + 63 = 9 * 13
? + 63 = 117
? = 54
Hope this helps!
