A taxi cab charges an initial fee of $3.50. Each 1/8 mile costs $0.23. Write an equation for the total cost, c, depending on the
Ymorist [56]

Answer:

3.50+0.125m(0.23) = C

Step-by-step explanation:

Initial fee- $3.50

Each 1/8 mile costs $0.23

A skateboard ramp is 40 feet long and rises from the ground at an angle of 33 degrees. How tall is the ramp?
olga_2 [115]

Answer:

The ramp is 21.8 ft tall.

Step-by-step explanation:

If you convert this into a triangle, 40 ft is the hypotenuse, 33° is the angle next to the right angle (on the horizontal line) and we need to find how tall the ramp is, which will be x. It is very helpful to draw a picture.

We will use the sine ratio because, starting from the given degree of 33, we have the hypotenuse value and need to find the value opposite the degree:

sine=\frac{opposite}{hypotenuse}

Insert values:

sin33=\frac{x}{40}

Multiply 40 to both sides to isolate the variable:

40(sin33)=40(\frac{x}{40})\\\\40*sin33=x\\\\x=40*sin33

Insert the value of x into a calculator:

x=21.7855614

Round if necessary:

x=21.8 ft

Done.

An electrical tower casts a 120-foot shadow. At the same time, a 10-foot
ki77a [65]

Set up a ratio with the height over the shadow.

Let the height of the tower be X

The ratio of the tower is x/120

The ratio if the sign is 10/8

Set them to equal and solve for x:

x/120 = 10/8

Cross multiply:

8x = 1200

Divide both sides by 8:

x = 1200/8

x =150

The answer is B. 150 ft.
