\frac{sin^2x}{cos^2x} + sin x *cscx\\ tan^2x + \frac{sin x}{sin x} \\ tan^2x + 1\\ sec^2x

\frac{sin^2x}{cos^2x} = tan^2x

csc x = \frac{1}{sinx}

tan^2x + 1 = sec^2x

Tju [1.3M]

The time take for the cyclist to travel from Fort Worth to Fresno is 90 \ hours

Explanation:

It is given that the distance from Fort Worth to Fresno is 1,530 miles.

The average speed of the cyclist is 17 miles per hour.

The time travelled by the cyclist can be determined using the formula,

Distance=Speed \times Time

Substituting the value of distance and speed, we get,

1530=17\times Time

Dividing both sides by 17, we get,

90 =Time

Thus, the time take for the cyclist to travel from Fort Worth to Fresno is 90 \ hours

when full the gas tank of a car holds 15 gallons. it now contains 12 gallons. what percent represents how full the tank is?
Masteriza [31]

Hello!

to find the percent of a whole, use this equation here:

(remaining) / (total) = X

X * 100 = %

in this case:

12 / 15 = 0.8

0.8 * 100 = 80

your answer is 80%

I hope this helps, and have a nice day!
