Answer:
the answer is 56
Step-by-step explanation:
2x+3x+5=90
5x=90-5
5x=85
x=85/5
x=17
YVZ= 3(17)+5
YVZ=51+5
YVZ=56
Answer:
CD=10.15m
Step-by-step explanation:
<u>Find the distance of BC.</u>
Tan(40)=55/BC
BC=65.55m
<u>Find the distance of BD.</u>
Tan(36)=55/BD
BD=75.70m
<u>Use BC and BD to find CD</u>
BD-BC=CD
75.70-65.55=CD
CD=10.15m
Using a linear function, the graph for the amount remaining of the trip is given at the end of this answer.
------------------------------
The linear function that models the distance remaining is given by:

In which
- D(0) is the total distance.
- v is the velocity.
In this problem:
- 500 miles, thus

- 55 miles per hour, thus:

The time it takes is:

Thus, the function is:

The graph is given at the end of this answer.

It is 8. Because 80×10=800
800=8 hundreds
Step 1: Find the factor of the number which is 64 = 4³
![\sqrt[3]{ 4^{3} }](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%204%5E%7B3%7D%20%7D%20)
Step 2: Apply Radical Rule: Which is
![\sqrt[n]{ a^{n} } =a](https://tex.z-dn.net/?f=%20%5Csqrt%5Bn%5D%7B%20a%5E%7Bn%7D%20%7D%20%3Da)
![\sqrt[3]{ 4^{3} } = 4](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B%204%5E%7B3%7D%20%7D%20%3D%204)
