Answer:

1600.

Step-by-step explanation:

5 % = 0.05.

Let the number be x then

0,05x = 80

x = 80/0.05

= 8000/5

= 1600.

1600.
I do the math a bit differently. I actually take 80 and multiply it by 20 because 5 goes into 100 20 times.

A car is traveling up a steep ramp to a parking garage.the ramp is 445 feet long and rises a vertical distance of 80 feet. What
Alecsey [184]
With the information provided in the problem, we can create a right triangle with the ramp as its hypotenuse, and  the vertical rise as its opposite side from its angle of elevation.
Let E be the angle of elevation from the car to the end of the ramp. We now know that the hypotenuse of our triangle measures 445 feet, and the opposite side measures 80 feet, so we need a trig function that relates our angle of elevation with the hypotenuse and the opposite side. That function is sine:
sine(E)= \frac{80}{445}
E=arcsine( \frac{80}{445} )
E=10.36

We can conclude that the angle of elevation from the car to the end of the ramp is 10.36°.

Answer:

Your first step in solving the system would be to substitute the value of a variable into one of the equations

Step-by-step explanation:

We know that x = 2y + 2 and y = -1/3x + 4, so we could insert one of these values as the variable in one of the equations

If we were to insert -1/3x + 4 for y, our new equation would be:

x = 2(-1/3x + 4) + 2 (as you can see, the value of y was inserted into the equation)

Evaluate the following expression when x = 3 and y = 4: Fraction with x squared plus y cubed in the numerator and 2 plus x in th
Black_prince [1.1K]
The answer is C. 14.6.

By evaluate, they mean substitute in the values of x and y to find the total of the expression, so you get:
(3^2 + 4^3)/(3 + 2) = (9 + 64)/5 = 73/5 = 14.6

I hope this helps!
