Students of an elementary school can wear only red or blue shirts. In one class of 28 students, 7 students are wearing blue shirts today and the rest of the students are wearing red shirts. What is the ratio of students wearing blue shirts to students wearing red shirts in that class today? Select each correct answer. Question 1 options: 1:7 7:21 7:28 For every student wearing a blue shirt, there were 3 students wearing red shirts. For every student wearing a blue shirt, there were 4 students wearing red shirts. For every student wearing a blue shirt, there were 7 students wearing red shirts.

Answers

Answer 1

Answer:

7:21   For every student wearing a blue shirt, there were 3 students wearing red shirts.

Step-by-step explanation:

If there are 28 students and 7 are wearing blue shirts then the number of students wearing red shirts is 28 - 7 = 21 so 21 students are wearing red shirts.

That means the ratio of blue shirts to red shirts is 7:21

That also means that for every student wearing a blue shirt, 3 were wearing a red shirt.

We get this because 21/7 = 3  and 7/7 = 1

True or False: by using the additive inverse property -64 - (-17) can be rewritten as -64 + 17

Answers

Step-by-step explanation:

Additive inverse is when you have a positive number, for example, and it becomes a negative.

Example: 8

The additive inverse of 8 is -8.

So the answer is false.

-64+17 and -64-(-17) is an example of communative property.

To make lemonade , Kate uses 1 cup of lemon juice and 2 cups of sugar. If she makes a larger amount of lemonade with 10 cups of sugar, how many cups of lemon juice does she need?

Answers

Answer:

5 cups

Step-by-step explanation:

Answer:

1/2 : 1

2 : 4

3 : 6

Notice that every ratio consists of a number and double the number.

For 1/2 cup lemon juice, use 1 cup sugar.

The amount of sugar is twice the amount of lemon juice.

The ratio is 1:2

Since you are told the ratio is 1:r, that means r is 2.

The unit rate is 2 cups sugar per cup of lemon juice.

19. What is the coordinate of the midpoint of the segment formed by the two points you found in Exercises 17 and 18?

Please explain

Answers

Answer:

0

Step-by-step explanation:

To find the coordinate of the midpoint of segment QB, first, find the distance from Q to B.

QB = |4 - 8| = |-4| = 4

The coordinate of the midpoint of QB would be at ½ the distance of QB (½*4 = 2).

Therefore, coordinate of the midpoint of QB = the coordinate of Q + 2 = 4 + 2 = 6

OR

Coordinate of B - 2 = 8 - 2 = 6

Coordinate of the midpoint of QB = 6

Coordinate of W = -8

Coordinate of A = 0

distance from W to A (WA) = |-8 - 0| = |-8| = 8

The coordinate of the midpoint of WA would be at ½ the distance of WA = ½*8 = 4.

Therefore, coordinate of the midpoint of WA = the coordinate of W + 4 = -8 + 4 = -4

Or

Coordinate of A - 4 = 0 - 4 = -4

Coordinate of the midpoint of WA = -4

Now, let's find the midpoint between the two new coordinates we have found, which are -4 and 4

Distance of the segment formed by coordinate -4 and 4 = |-4 - 4| = |-8| = 8

Midpoint = ½*8 = 4

Coordinate of the midpoint = -4 + 4 = 0

Or

4 - 4 = 0

Donis bought a t-shirt for $15 and jeans for $35.50. If the sales tax rate is 8.25%. What is the sales tax for the t-shirt and jeans in dollars and cents? *

Answers

Answer: 4 dollars and 17 centsThis is the same as saying $4.17

====================================================

Explanation:

15+35.50 = 50.50 dollars is the total before tax is applied.

Take 8.25% of this to get

0.0825*50.50 = 4.16625

and this rounds to 4.17, which is the amount of sales tax charged.

$4.17 = 4 dollars + 17 cents

---------

Extra info:

The grand total will be 50.50+4.17 = 54.67

Another way to get the grand total is to multiply 1.0825 by the previous subtotal (50.50) getting 50.50*1.0825 = 54.66625 and that rounds to 54.67

The multiplier 1.0825 effectively means "increase by 8.25%"

George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL. What is the volume of the object?

Answers

Answer: 20 mL

Step-by-step explanation:

According to Archimedes, the upward force exerted on a body immersed in a fluid is equal to the weight of the fluid the body displaces.

i.e. weight of the object = weight of the fluid displayed

Given: George put 25 mL of water into a graduated cylinder. After adding a solid object, the water level in the cylinder rose to 45 mL.

So, the volume of the object = New volume - Original volume

= 45 mL - 25 mL

= 20 mL

Hence, the volume of the object =20 mL

Ari is jogging at an average rate of 2.25 meters per second. Find the time it will take him to jog 270 meters.

Answers

Answer:

120 seconds/2 minutes

Step-by-step explanation:

divide the distance (270 m) by the rate (2.25 m/s) and you have 270/2.25 = 120 seconds, or 2 minutes.

It will take Ari 120 seconds to jog 270 meters.

To find the time it will take Ari to jog 270 meters at an average rate of 2.25 meters per second, we can use the formula:

Time = Distance / Rate

where:

Distance = 270 meters

Rate = 2.25 meters per second

Time = 270 meters / 2.25 meters per second

Time = 120 seconds

Therefore, it will take Ari 120 seconds to jog 270 meters.
