Answer

It will take him 450 minutes to read 90 pages.

Explanation

Luis can read 3 pages every 15 minutes.

You are trying to find how long it will take him to read 90 pages.

Set up this ratio.

$\frac{15}{3} =\frac{x}{90}$

To get from 3 to 90, you multiply by 30. Do the same thing to 15.

15 times 30 is 450.

It will take Luis 450 minutes to read 90 pages.

Calculate the velocity of a car traveling in a straight path due east with a distance of 16 meters in 2 seconds. Question 1 opti

AleksAgata [21]

Answer:

E 8 m/s

Step-by-step explanation:

The magnitude of the velocity (the speed) is the number of meters divided by the number of seconds. (That's what meters per second means.)

|V| = (16 m)/(2 s) = (16/2) m/s = 8 m/s

Velocity is a vector quantity, so must include a direction along with the magnitude.

V = E 8 m/s

Given that f(x) = x2 – 3x – 28 and g(x) = x - 7, find

gregori [183]

Answer:

$(f-g)(x)=x^2-4x-21$

Step-by-step explanation:

We are given the two functions:

$f(x)=x^2-3x-28\text{ and } g(x)=x-7$

And we want to find:

$(f-g)(x)$

This is equivalent to:

$=f(x)-g(x)$

Substitute:

$=(x^2-3x-28)-(x-7)$

Distribute:

$=x^2-3x-28-x+7$

Rearrange:

$=(x^2)+(-3x-x)+(-28+7)$

Hence:

$(f-g)(x)=x^2-4x-21$
