2(2x-4)+x=7
= 4x-8+x=7
= 4x+x-8=7
= 5x=7+8
= 5x=15                     dividing both sides by 5
= x=15/5
= x=3
so x is 3

The recommended angle for a wheel chair ramp is 5 degrees. If the rise of the ramp to go up the steps is 5 feet, find the horiza
HACTEHA [7]

Answer:

1. Draw out a diagram as a triangle with one side as the 5' rise, the other side as the horizontal run, and the hypotenuse as the ramp.

2. Put the 5 ° in as the angle between the run and the ramp.

3. Let the run = x. Using trigonometry (needed!) the tangent angle (tan) of 5° = opposite/adjacent = 5/x.

4. So x = 5/tan(5°). you will need a scientific calculator to solve.

Bob the Wizard makes magical brooms. He charges 125125125 gold pieces for each magical broom he makes for his customers. He also
Agata [3.3K]

The function formula will be

G= 50 + 125x

Since we have given that

Charges per each magical broom he makes for his customers = 125 gold pieces

Charges of one-time fees = 50 gold pieces

Let the number of magical brooms he makes be 'x'.

Let the total number of gold pieces be 'G'.

According to the question, it becomes

G= 50 + 125x

Hence, the function formula will be

G= 50 + 125x

A formula is a fact or rule written in mathematical symbols. An equal sign usually connects two or more quantities. If you know the value of one quantity, you can use a formula to find the value of the other.

Solve for theta in the interval 0&lt;theta&lt;2pi.     <br>cos(theta)sin(theta)-0.5 cos(theta)=0
riadik2000 [5.3K]
CosOsinO - 0.5 cosO = 0

cosO(sinO - 0.5) = 0

so cosO = 0 ,  sin O = 0.5

cosO = 0  gives O = pi/2 , 3pi/2
sinO = 0.5  gives O = pi/6, 5pi/6.
