The ratio of girls to boys in a swimming club was 2 : 4. There were 14 girls. How many total members were there in the club?

Answers

Answer 1

Answer:

Step-by-step explanation:

the ratio 2:4 can be reduced to 1:2,

where the number of girls corresponds to the 1 and the number of boys corresponds to the 2.

If there are 14 girls, then there must be 28 boys (14 x 2 = 28).

Now to get the total number we need to add the total number of boys and girls together.

So 14 + 28 = 42

Hope it helps :)

Answer 2

Answer:

Step-by-step explanation:

14 + 28 = 32

2 x 7 = 14

4 x 7 = 28

1) Alexa won 80 super bouncy balls playing horseshoes at her school's game night. Later, she gave two to each of her friends.
She only has 8 remaining. How many friends does she have? 2) Jane spent half of her weekly allowance playing mini-golf. To earn more money her parents let her wash the car for $20. What is
her weekly allowance if she ended with $32? 3) 229 students went on a field trip. Six buses were filled and 5 students traveled in cars. How many students were in each bus?

Answers

Answer:1 is 36 friends. 2 is $24 as her weekly allowance. 3 is 37 students on each bus

Step-by-step explanation:1. 80-8 because 8 is the amount she has left. You would get 76 which is the amount she gave away. Then you divide 76 by 2 because she gave 2 balls to 1 friend. Then you get the amount of friends she has.

2. When we read the problem it says she spent half of her allowance on mini golf. The half is very important. She earns $20 from cleaning her parent’s car and ends up with $32 all you do is subtract the $20 from $32 because it’ll leave you with 1/2 the money she began with (32-20=12). Then she she already spent half of the money you can either add 12 or multiply the 12 by 2 to get your answer (12+12=24 or 12•2=24).

3.(229-5) you’re subtracting 5 from the 229 students because 5 of them traveled in car. Then you do 224 students divided by 6 buses and you should get 37 students per bus.

What is the measure of each angle in a pentagon if the lengths of all five sides are equal?
A. 180
B. 120
C. 108
D. 60

Answers

Answer:

C (108)

Step-by-step explanation:

Angles in a pentagon must add up to 540 degrees.

All sides equal mean all angles are equal

so all you must do is divide 540 by 5, which gets you to 108.

You can use inverse operations to check the work

108 x 5 = 540

Hw assignment. what is wrong?

Answers

On the second step, the student said x - x is 2x, when it should equal 0
The second step should read
6x - 5 = 7
The student should then add 5 to each side
6x = 12
The student should then divide by 6 on both sides
x = 2

Answer:

the second and first steps. in the second part, x, should be substracted by x

so no xz should remain in the second part of the equation.

the second step would be:

6x - 5 = 7

What do you do if a variable does not cancel out?

Answers

It always cancels out lol

In general, if you have an equation in which all your variables cancel out, then it tells you that your equation is either true or false, independently of the vaues your variables take. In your example, you arrive at the equation 0=1, which is false. No matter what values you take for x and y, it will never be true.

A rectangular fish tank is shown above. The base of the tank has an area of 58.4 feet2. What is the volume of water in the tank?

Answers

Answer:

525.6 ft^3 based on a Height of 9 ft

Step-by-step explanation:

Given data

Area of Base= 58.4 ft^2

The expression for the volume of a rectangular tank is given as

Volume= L*W*H

Volume= Area*Height

Although the question was not specific about the height, it is important that we have the height to get the volume

Say the height is 9 ft

Hence the volume is

V= 6*58.4*9

V= 525.6 ft^3

Explain how to use the unit-factor method to convert 120 pounds to kilograms.

Hint: 1 kilogram=2.2 pounds

To write the unit factors, use the / symbol, like this: 1 gallon/3.79 liters.

Answers

The converted units is 120 pounds = 54.5 kilogram

How to convert the units?

As a general rule, we have:

1 kilogram=2.2 pounds

Multiply both sides by 120

120 * 1 kilogram=2.2 pounds * 120

Divide both sides by 2.2

120/2.2 * 1 kilogram=2.2 pounds * 120/2.2

Evaluate the products

54.5 kilogram= 120 pounds

Rewrite as:

120 pounds = 54.5 kilogram

Hence, the converted units is 120 pounds = 54.5 kilogram

24 59' 60'' is equivalent to what degrees

Answers

Answer:

25 degrees

Step-by-step explanation:

The computation is shown below:

24°59'60" = 24°+59'+60"

Now

As we know that

1'=60"

i.e. (1 minute = 60 seconds)

so,

24°+59'+60" = 24°+59'+1'

=24°+60'

Also,

1°=60'(1 degree=60 seconds)

= 24°+1°

=25°

x = (9/72)*24
