Step-by-step explanation:

(a)

constant of proportion = [tex]\frac{d}{t}[/tex] ( d is distance, t is time )

Use any ordered pair from the table

Using d = 225 and t = 5 , then

constant = [tex]\frac{225}{5}[/tex] = 45

(b)

Unit rate is then 45 miles per hour

(c)

The equation relating the quantities is

d = 45t

Answer:

Step-by-step explanation:

1200-800+1600+50-105=1945

Answer: B.

The balance starts at $1200. On July 19th, there's an outgoing transfer of $800, so you subtract 800. The remaining balance is 1200-800=$400.

On July 20th, there's an incoming transfer of $1600, so you add that to $400 to get $2000.

On July 23rd, you the account recieves $50 more, so you add that to get $2050.

On July 24th, you have to pay $105, so you subtract that to get $1945.00.

Answer:

x=22

Step-by-step explanation:

Label the intersection point between K and J as H. Similarly, label the intersection point between K and L as M.

The triangle proportionality theorem states that HK/JK=MK/LK.

Substitute the values into the equation above. HK=36-6=30. LK=2x-4+8=2x+4.

30/36=2x-4/2x+4

Now, solve:

30(2x+4)=36(2x-4)

60x+120=72x-144

12x=264

x=22

Answer:

sqrt(26) units

Step-by-step explanation:

Use the formula d=sqrt((x2-x1)^2 + (y2-y1)^2). d is the distance, and (x1, y1) and (x2, y2) are the points.

d=sqrt((4-(-1))^2 + (2-3)^2)

 =sqrt(5^2 + (-1)^2)

 =sqrt(25+1)

 =sqrt(26)

Answer: 1 3/4 × 1 1/2

Step-by-step explanation:

Since Harry needs 1 3/4 cups of flour for one batch of cookies, but he wants to make 1 1/2 batches, the equation that can be used to find how many cups of flour Harry will need will be:

= (1 3/4 / 1) × 1 1/2

= 1 3/4 × 1 1/2

Therefore, to make 1 1/2 batches, the cups of flour needed will be:

= 1 3/4 × 1 1/2

= 7/4 × 3/2

= 21/8

= 2 5/8 cups of flours.

Answer:

2 quarts apple juice and 8 cups cranberry juice

9 cups apple juice and 3 pints cranberry juice

Step-by-step explanation:

We can easily obtain the answer by converting all the volumes to the same unit and comparing each of them, to see if they can make up to a gallon.

1). 6 pints apple juice and 6 cups cranberry juice

Let us convert pints and cups to gallons

1 pint = 0.125 gallons

6 pints = 6 X 0.125 = 0.75 gallons

1 cup = 0.0625 gallons

6 cups = 6 X 0.0625 =0.375 gallons

Total juice got from here is 0.75 +0.375 = 1.125gallons.

This cannot fit into the one-gallon pitcher as it is more in volume than a gallon.

2) 2 quarts apple juice and 8 cups cranberry juice.

2 quarts = 0.5 gallons

8 cups = 0.5 gallons.

Total juice got here is 0.5 + 0.5 = 1 gallon.

This can fit into the 1-gallon pitcher

3). 5 pints of apple juice and 2 quarts of cranberry juice

5 pint = 0.625 gallons

2 quarts = 0.5 gallons

Total juice got here is 0.625+ 0.5 = 1.125 gallon

This cannot fit into the 1-gallon pitcher

4). 9 cups of apple juice and 3 pints of cranberry juice

9 cups = 0.5625 gallons.

3 pints = 0.375 gallons

Total juice got here is 0.5625 + 0.375 = 0.9375 gallons.

This can fit into the 1-gallon pitcher because it is of less volume.

Hence, only these combination of drinks can fit into the 1-gallon pitcher:

2 quarts apple juice and 8 cups cranberry juice

9 cups apple juice and 3 pints cranberry juice

Answer:

Step-by-step explanation:

Given f(x) = 3x^3 -5x + k, and x-2 is a factor of f(x), then what is the value of k?

This is an interesting question, since I have to think I have ever seen a question like this asked before.

    3x³ - 5x + k   i'll try dividing by x-2  and adjust k so there is no remainder

                           3x² + 6x + 7

       x-2   |  3x³ + 0x² - 5x + k

                 3x³ - 6x

                          6x² -  5x

                          6x² - 12x

                                   7x  + k

                                   7x  - 14

                                            0    remainder is 0 if k = - 14

when I graphed   3x³ - 5x -14   and   (x-2)(3x² +6x +7)  the graphs were equivalent

The salesperson will have a commission of $262.5 and earn $612.5 in one week if he sold $750 worth of merchandise.

We first calculate the 35% commission on the $750 sales of merchandise, and then add the result to his weekly earning of $350.

35% commission on $750 = (35 × $750)/100

35% commission on $750 = $2625/100

35% commission on $750 = $262.5

salesman's earning for the week = $350 + $262.5

salesman's earning for the week = $612.5

In conclusion, the salesman will earn $612.5 if he sold $750 worth of merchandise in one week, which is the sum of his $350 per week earning and the 35% commission.
