Regina travels ½ of a kilometer for every ¼ of a minute she drives. You were told that the trip from Times Square to Pelham Parkway is 72 kilometers. How many minutes would her trip have taken by car?

Answers

Answer:

36 minutes.

Step-by-step explanation:

The best way to solve this is to find how much distance is traveled in a minute and then divide the total distance by the distance traveled in a minute. Now let's apply.

1/4 x 4 = 1 minute, so in this problem, 1/2 x 4 = 1 minute.

1/2 x 4 = 2.

72 / 2 = 36.

Her trip would have taken 36 minutes by car.

Answer:

36 minutes.

Step-by-step explanation:

For every mile she takes it's 1/2 of a minute. Then just do 72/2 and get 36 :)

A school administrator bought 6 desk sets. Each set consists of one table and one chair. He paid $48.50 for each chair. If he paid a total of $663 for the 6 sets, the cost of each table is
a.$ 54.5
b.$62.00
c.$ 110.50
d.$ 159.00

Answers

Answer:

b. $62

Step-by-step explanation:

48.50 * 6 = 291

663 - 291 = 372

372 / 6 = $62

B. 63.00$ hope it helps

Juli says she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6:10.
Which statement explains whether Juli is correct?
a. She is correct because she can multiply 6 and 10 by any number to form an equivalent ratio.
b. She is correct because 6:10 can be written as 1:2 and there are an infinite number of ratios for 1:2.
c. She is not correct because the multiplication table does not include multiples of 10.
d. She is not correct because 6:10 is equivalent to 3:5 and there are only 9 ratios in the multiplication table that are equivalent to 3:5.

Solve for y.
6y-1.5x=8

Answers

Hope this helped! good luck

Answer: Y = 0.25x + 4/3

Step-by-step explanation:

Step 1: Add 1.5 to both sides

-1.5x + 6 + 1.5x = 8 + 1.5x

6y = 1.5x + 8

Step 2: Divide both sides by 6

6y/6 = 1.5x + 8/6

Y = 0.25x + 4/3

Simplify the following if x = 2 & y = 5:

1. 3x + y =

2. 3x + 2y =

3. 3y + 2x =

4. 10x + 4y + 7x =

What was Jay’s error? Find the correct answer.

Step-by-step explanation:

Answer:

he should have first preformed oprations in the pratheses so he should have done (3+12/3) first to get 3*(3+4)-4 then do (3+4) and have 3*7-4 next he should do 3*7 and get 21-4 do that and get the answer 17

Step-by-step explanation:

Jayden used a Groupon at the local pizza shop. Instead of paying $15, for the pizza, he paid $12.

Haley and Arianna agree that the percent of decrease is 20% but their explanations differ. Haley says to find the 20%, you have to determine what percent of 15 is 12. Arianna thinks you have to determine what percent of 15 is 3. Who is correct? Explain your thinking.

Answers

Answer:

She is correct because they need to find how much is the discounted price, which is 3. So to see what percentage it is, they need to see how much 3 is worth in comparison to 15. If we spilt 15 into 5 parts to make every part worth 20%, the answer would be 3. Thus Arianna is correct.

The measures of the angles of △ABC are given by the expressions in the table.

Angle Measure
A (6x−1)°
B 20°
C (x + 14)°
What are the measures of angles A and C?

Answers

Answer:

First You add all given angles up to equal 180 to give you x then you plug x into equations

Step-by-step explanation:

A= 125 degrees

C= 35 degrees

Answer:

Angle A = 125°

Angle C = 35°

Step-by-step explanation:

This is the equation you would have to solve:

Angle A + Angle B + Angle C = 180°

Fill in the values given:

(6x-1)° + 20° + (x+14)° = 180°

The parentheses don't really matter here. Go on to combine like terms. This gives you:

7x + 33 = 180°

Solve for x. Subtract 33 on both sides. This gives 7x = 147. Divide both sides by 7. This gives x = 21.

Now, go back and fill in 21 for x in the expressions for angles A & C.

Angle A:

6(21) - 1 = 125°

Angle C:

21 + 14 = 35°

You can check your answers using the first equation I mentioned:

Angle A + Angle B + Angle C = 180°

125° + 20° + 35° = 180°

This is a true equation. Therefore, the final answers are:

Angle A = 125°

Angle B = 20°

Angle C = 35°

Which numbers have an absolute value of 4?(you can pick more than one)

4
-4
2
8

Answers

Answer:

4 and -4

Step-by-step explanation:

absolute value is always going to be positive and the overall value will only change if it is negative. so the "|4|" (absolute value of 4) is the same as "|-4|" (absolute value of negative 4)

You can pick 4 and -4. Absolute value is the distance from 0 on a number line. So if I have a 2 on the number line, the amount of space from the 0 is 2. If I have a negative 9 on a number line then the absolute value is positive 9. A absolute value is always positive, even if the number is negative. Hope this helps!
