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?
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 :)

25square units
Step-by-step explanation:
you have to find the area of the blue square. First you have to find the side length of the square. the missing length is called the hypotenuse because it is the longest side of the triangle. It is probably 5 units, because in comparison the the 4 units it looks about 1 unit longer. now all that's left is 5x5=25
A large bottle of juice contains 500 milliliters of juice. A small bottle contains 50% as much juice as the large bottle. How many milliliters of juice are in the small bottle?
Answer:
250 milliliters of juice.
Step-by-step explanation:
You need to find 50% of 500. What I like to do in this situation is turn it into a basic division problem:
500 ÷ 2
500 divided by 2 is 250.
The perimeter of a rectangular garden is 37.5 feet. The width is x, and the length is 15 ft. Use the equation 2(x + 15) = 37.5 to determine the width, in feet, of the garden?
Answer:
2.5
Step-by-step explanation:
37.5/15=2.5
Answer:
11.25
Step-by-step explanation:
first what u do is u just make 2(x+15)=37.5 into 2x+15=37.5
and then u do 2x=37.5-15
that will give u 2x=22.5
then u do this x=22.5/2
and x = to 11.25
-3x + 1 < 7 on number line
Answer:
D. x is greater than -2
Step-by-step explanation:
Ok so,
-3x + 1 < 7
First, do the opposite of +1 which is -1 so you have to subtract 1 from both sides. Which should look like this.
-3x < 6
Then you divide -3 with 6 which will give you -2. You change the inequality sign becuase you divided with a - number.
Hope his helps. Have a good day!

The equation 9t = 27.99 models a constant rate situation.
Drag and drop the value of 5t in the box. 5t=
Answer:
The value of 5t will be 15.55
Step-by-step explanation:
Given equation is;
9t = 27.99
As it is stated that the relationship is constant, therefore, we will find the value of t by dividing 27.99 by 9
Now, we will put t=3.11 to find 5t.
The value of 5t will be 15.55
