If 30% of a number equals 8, find 90% of that number.

Answers

Answer:

8.88

Step-by-step explanation:

I believe it is 8.88 becuase this question is asking to find 90% pf that number.

What do you need to do?

you have to make a proportion.

8/x 90/ 100

You would now cross multiply. 90* x = 90x 8*100= 800

the equation you would need is 90x = 800. divide them and you get 8.88.

ROUNDED: you get 9.

I believe this is correct sorry if it was incorrect.

anwser: 8.88

The volume of a right rectangular prism is 70 7/8 cubic feet and its base is a square with a side length of 4 1/2 feet. what is the height?

Answers

Answer:

7/2 feet

Step-by-step explanation:

Volume of Right Rectangular Prism: V = w * h * l

You are given the volume, and the base (which would include l and w)- and are told to find h.

70 7/8 cubic feet = 4 1/2 feet * h * 4 1/2 feet (simplify the right side)

70 7/8 cubic feet = 81/4 feet squared * h (divide both sides by 81/4)

7/2 feet = h

The height will be 7/2

Which two parallelograms have the same area?

Answers

Answer:

Idc

Step-by-step explanation:

I don’t really wanna help, so thanks for the points! Don’t scroll down! I’m warning you!!!

Figure 1 and Figure 4 have the same areas because the area of a parallelogram is just length times width.

Figure 1: 15×4=60 cm

Figure 2: 18×3=54 cm

Figure 3: 11×6=66 cm

Figure 4: 12×5=60 cm

As you can see, figure 1 and figure 4 have the same areas. So, C is the correct answer.

The answer is figure 1 and 4

Find the value of x:

Answers

Answer:

x = 3

Step-by-step explanation:

These angles are vertical angles. Vertical angles equals to on another but on the opposite side. Since they equal to another you do:

(10x + 1) = (12x - 5)

Add 5 on both sides:

10x + 6 = 12x

Subtract 10x on both sides:

6 = 2x

Divide 2 on both sides:

3 = x

Answer:

(10x+1)°=(12x-5)°. [vertically opposite angle]

1+5=12x-10x

6= 2x

3=x

therefore,x=3

NO LINKS PLEASEE!! IM BEGGING YOU NO LINKSS!!!

Answers

Answer:

A = (1/2)Pa = Pa/2

You can multiply both sides by 2 to eliminate the fraction on the right side:

2A = 2(Pa/2) = Pa

Then divide both sides by a (or multiply both sides by 1/a) to leave P alone on the right side:

(2A)(1/a) = 2A/a = (Pa)(1/a) = P

Rewriting:

P = 2A/a

You could also have divided by a first then multiplied by 2; which you should do first does not matter in this example.

Answer:

1. Mean: 10 Median: 11 Mode: 13

2. Mean: 26.7 Median: 20.5 Mode: 20

Step-by-step explanation:

1. Mean: 6+7+11+13+13 = 50 then, 50/5 = 10

Median: 6, 7, 11, 13, 13 in the middle: 11

6- crossed

13- crossed

7- crossed

13- crossed

That leaves 11!

Mode: 13 appears two times. All the other numbers only appear once.

2. Mean: 0+20+20+30+40+70 = 160 then, 160/6 = 26.7 ( rounded to nearest tenth)

Median: 0, 20, 20, 30, 40, 70

0- crossed

70- crossed

20- crossed

40- crossed

20- crossed

30- crossed

They all are crossed, but the last 2 to be crossed are 20 and 30. The middle of those two numbers is 20.5 therefore, the median is 20.5!

Mode: 20 appears twice while the rest only appears once.

I hope this helps, good luck! :)

Maggie is buying a jacket. The expression shown represents the sales tax on the jacket price, j.

0.08j
Write an expression in terms of j to represent the total amount that Maggie spends on the jacket, including tax.

Answers

Answer: 1.08j

Step-by-step explanation: if we add 8% of something to itself, we now have 108%, right

1.08j

I’m not 100% sure tho

The expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

What is Percentage?

A percentage is a way to describe a part of a whole. such as the fraction 1/4 can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

As it is given that the cost of the jacket is j, while the tax on the jacket is 0.08j. therefore, the total cost of the jacket can be written as the sum of the cost of the jacket and the tax on the jacket.

Thus, the total cost of the jacket = Cost of jacket + Tax on the jacket

= j + 0.08j

= 1.08j

Hence, the expression represents the total amount that Maggie spends on the jacket, including tax is 1.08j.

It says “If 4 apples cost $1.00, what would be the cost of 10 apples?” -

Answers

Answer:$8.50

Step-by-step explanation: If 4 apples are $1.00 that means that one apple would be 25¢. 10 apples would mean $8.00 and since 2 apples are left that would be 50¢. Hence, the answer would be $8.50

It might be 2 dollars and 50 cents because since every apple is 25 cents and if you buy 8 apples it would be 2 dollars and another 2 apples will be 50 cents but I’m not sure
