The Brown family is on their way home from a cross-country road trip. During the
trip, the function D(t) = 3,500 - 20t can be used to represent their distance, in
miles, from home after t hours of driving.
What is the value of D(15)?
3200
3465
-3200
174.25

Answers

Answer 1

Answer:

Step-by-step explanation:

D(15) = 3500 -20(15)

D(15) = 3500 - 300

D(15) = 3200

In 15 hours of driving the Brown family is 3200(no unit given) away from home.

The fourth answer

Step-by-step explanation:

Answer:

{6,9}

Step-by-step explanation:

The table values are given as;

x   y

0  0

2  3

4  6

Take the values as coordinates in form of {x, y} , to have the following;

{0,0} , {2,3} , {4,6}

Find the slope using the coordinates as;

m=Δy/Δx

m=3-0/2-0 = 3/2

The slope m = 3/2

So from the answer choices, the coordinates that can give a slope of 3/2 will be:

{6,9}

The x coordinates increase by 2units while those of the y coordinates increase by 3 units.

Write the unit rate for the situation. Please help

In a collection of​ coins, the number of quarters is​ one-third the number of pennies. The number of quarters is Q. The number of pennies is P. What is the correct formula relating Q to​ P

Answers

Answer:

Q = P/3

Step-by-step explanation:

Let the number of quarters be Q

Let the number of pennies be P

If the number of quarters is​ one-third the number of pennies, this can be expressed as;

Number of quarter = 1/3 of pennies

Q = 1/3 of P

Of means multiplication

The expression becomes;

Q = 1/3 × P

Q = P/3

Hence the formula relating Q to P is

Q = P/3

Answer:

C) x=35

Step-by-step explanation:

First, we know that the total amount of degrees in a rotation is 360. As the picture tells us, the opposite angles will be exactly the same. Taking this information, we can have the following equation:

4x + 2(3x+5) = 360

By now using our linear equation skills, we get:

10x+10=360

10x=350

x=35

The degree amount of x for c) is 35 degrees.

C. Since the angles form a linear pair, their sum equals 180.

So, 2x + 3x + 5 = 180

x=35

D. Since the angles are verticle, they equal each other.

So, 3x + 5 = 5x -57

x=31

What is the transformation of geometry over the coordinate plane?

Transform the shapes on a coordinate plane by rotating, reflecting, or translating them. Felix Klein introduced transformational geometry, a fresh viewpoint on geometry, in the 19th century.

here,
When rotation 180° clockwise takes place then the sign of the coordinate is reversed as if it is positive then it becomes negative and vice versa.

So the algebraic representation for a rotation 180° clockwise of (x, y) is (-x, -y).

Thus, the required algebraic representation for a rotation 180° clockwise is -x, -y. Option D is correct.

Step-by-step explanation:

A public swimming pool that holds 45,000 gallons of water is going to be drained for maintenance at a rate of 100 gallons per minute. The amount of water, w (in gallons), in the pool after t minutes is given by the function w = 45,000 – 100t. How many minutes will it take to empty the pool?

Answers

Answer:

450 minutes

Step-by-step explanation:

Given

w = 45000 - 100t

Required

Determine how long it'll take to empty the pool

Being empty means there's no water in the pool.

So, we have to set w to 0 to get the value of t

i.e w = 0

Substitute 0 for w in w = 45000 - 100t

0 = 45000 - 100t

Collect Like Terms

100t = 45000

Divide through by 100.

t = 450

Hence, it'll take 450 minutes to empty the pool

Comment on supplementary angles

Angles that form a linear pair are supplementary. Angles do not have to form a linear pair to be supplementary. They merely have to have a sum of 180°. Here, the supplementary angles of interest do form a linear pair, so finding the other angle of the pair means only finding the other point that names the line being formed by the pair.
