The bus fare in a city is People who use the bus have the option of purchasing a monthly coupon book for With the coupon book,

SashulF [63]

Answer:

26 times

Step-by-step explanation:

The question has missing details. However, the given parameters are

Given

Without Coupon

Bus Fare = $2.00

With Coupon

Coupon = $39.00

Bus Fare = $0.50

Represent the number of fares with x

Without Coupon, cost of fares is

Cost = 2x

i.e.

f(x) = 2x

With Coupon, cost of fares is

Cost = 39 + 0.5x

i.e.

g(x) = 39 + 0.5x

To calculate when both fares will be equal, we must have:

f(x) = g(x)

2x = 39 + 0.5x

Collect like terms

2x - 0.5x = 39

1.5x = 39

Solve for x

x = 39/1.5

x = 26

This implies that, for both cost to be equal, the person must go 26 times

A ramp leading into a building makes a 15 degree angle with the ground. The end of the ramp is 10 feet from the base of the buil

stiks02 [169]

Answer:

The length of the ramp is x = AC = 10.35 feet

Step-by-step explanation:

From the ΔABC

AC = x = length of ramp

BC = 10 feet

$\theta = 15$ °

$\cos 15 = \frac{BC}{AC}$

$\cos 15 = \frac{10}{x}$

x = 10.35 feet

Therefore the length of the ramp is x = AC = 10.35 feet

False

because tan^2 45 = 1^2 = 1
and sec^2 x = 1/ cos^2 45 = (sqrt2)^2 = 2

so the sum = 3

They recognize that international automobiles manufactured in the U.S. were typically commercial goods at the price fixed, either new used or, whether for personal use and sale: cars - 2.5%.

Through task, we learn that the overseas Fiat car which cost him 6250.

We get the proportion as follows:

$\to 100 :6250=2.5: x\\\\\to \frac{100}{6250}=\frac{2.5}{x}\\\\\to 100 \times x = 2.5 \times 6250\\\\\to x= \frac{2.5 \times 6250}{100}\\\\\to x= 156.25$

The duty he has to pay is 156.25.
