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.

Hey There!

To find the perimeter of any figure all you have to do is add up all of the side lengths

5+5+7+11+7+16=53

so the perimeter is equal to 51

Note: the 18 is from the bottom length of the figure

you would have to add the 5 and 11

the extra seven is from the very right side length

Find the area of the figure below

Answers

Answer:

96m²

Step-by-step explanation:

Hello there!

The figure shown is an irregular figure so to make it easier we are going to split the irregular figure into two regular figures

A triangle with a height of 6 m and a base of 12 m

and a parallelogram with a base of 10m and a height of 6m

Now lets find the area of each individual shape

For the triangle:

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base and h = height

Knowing the base and height all we have to do is plug in the values into the formula

[tex]A=\frac{6*12}{2} \\6*12=72\\\frac{72}{2} =36[/tex]

so we can conclude that the area of the triangle is 36 m²

Now lets find the area of the parallelogram

The area of a parallelogram can simply be found my multiplying the base and height

so A = 10 * 6

10 * 6 = 60

so the area of the parallelogram is 60 m²

Finally we add the two areas together

60 + 36 = 96m²

Thus the area of the irregular figure is 96m²

choose all that are correct.

1. Random samples from the same population will vary from sample to sample.

2. as the sample size increases, the sample distribution more closely resembles the population distribution.

3. vallues of a sample statistic of different random samples of the same size from the same population will be the same

4. if a random sample is chosen from a population with a large cluster of points at the maixmum, the sample is likely to have at least one element neat the maximum

We will want to solve for x
We will start by multiply both sides by 24 so we can cancel out the 24 on the left and get x by itself
Now we have
x = (9/72)*24
we can first multiply 24 by 9 to get 216
Now we have
x = 216/72
216 divided by 72 will get us 3
x = 3

Find the missing length indicated?

Answers

Answer:

D. 15

Step-by-step explanation:

Let the missing length be represented as x.

Thus:

(24 - x)/12 = x/20 => angle bisector theorem

Cross multiply

20(24 - x) = x(12)

480 - 20x = 12x

480 - 20x + 20x = 12x + 20x

480 = 32x

480/32 = 32x/32

15 = x

Missing length = x = 15

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.

Answers

Answer:

A) He used 2/3 yard of wire

B) He had 4/15 yard of wire left

Step-by-step explanation:

An electrician had 14/15 yard of wire

He used 5/7 of the wire

A) How many many parts of wire did the Electrician use?

This is calculated as:

5/7 of 14/15 yard of wire

= 5/7 × 14/15 yard

= 2/3 yard of wire

He used 2/3 yard of wire

B) How many yards of wire does the Electrician have left?

This is calculated as

14/15 yard - 2/3 yard

Lowest common denominator is 15

Hence:

14 - 10/15

= 4/15 yard of wire left
