Answer:

2:11

Step-by-step explanation:

Answer:

11 : 2

Step-by-step explanation:

We have the ratio 22:4 and we are asked to simplify it.

Ratios work like fractions, you need to divide both sides by the same number until you reach a number that cannot be divided equally both towards the numerator and denominator unless making it a decimal.

If so, we can divide both of the numbers in this ratio by 2 because they are divisible by that.

22 : 4

22 / 2

4 / 2

11

2

11 : 2

Since both numbers cannot be divided equally without ending in a decimal, therefore, the simplified ratio is 11 : 2

Answer:

Median would objectively fair better as a way to calculate grades. Median value doesn't rely on all of the assets that make up the dataset, unlike the mean method would. The mean sums up every asset, which can lead to it being unreliable. The median, however, is a middle-most value within a list of numbers, which would make it a more accurate method of grading. Overall, it would make the most sense for Han's history teacher to use the median method for grading homework.

Part A: Shiloh would collect data on which student spends the most time at the beach

Part B: It is a statistical question

Part A I would expect her to collect a certain number of times, such as each dot 1 hour. Part B This is a statistical question.

Statistics is the study of the discipline that concerns the organization, collection, analysis, and presentation of data.

Part A: we have to describe the data you would expect her to collect from this question.

I would expect her to collect a certain number of times, such as each dot 1 hour.

For example, if she had a dot plot or a chart to divide how much time each student stays at the beach, along with her collecting the students' names to figure out the answer to her question.

Part B:  Explain whether this is a statistical question. If this is not a statistical question, then modify the question to make it statistical.

This is a statistical question.

A statistical question is a question that can be solved by collecting data that varies.

To even solve this, we need to collect data. The easiest way to solve this is with a dot plot. we also need the student's data, such as their names and how many hours at the beach they spent time there.

Answer:

the volume for the second page is 607.5

Step-by-step explanation:

Answer:

40 and 202.5 m³

Step-by-step explanation:

(7)

Since the figures are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{PQ}{16}[/tex] = [tex]\frac{30}{12}[/tex] ( cross- multiply )

12 PQ = 480 ( divide both sides by 12 )

PQ = 40 in

-------------------------------------------------------------------

The volume (V) of a pyramid is calculated as

V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of the base and h the height ) , then

V = [tex]\frac{1}{3}[/tex] × 9² × 7.5

   = [tex]\frac{1}{3}[/tex] × 81 × 7.5

   = 27 × 7.5

   = 202.5 m³

Answer:

Step-by-step explanation:

44 + 99 + x = 180

143 + x = 180

x = 37

Answer:

A. 4 * 3 * 7 and 1 * 3 * 4

D. 4 * 6 * 1 and 6 *4 * 3

Step-by-step explanation:

First I'll find the volume of the figure itself.

I'll split it into two figures. A 4 * 3 * 7 rectangular prism and a 1 * 3 * 4 rectangular prism. (That confirms A as one of the answers.)

(4 * 3 * 7) + (1 * 3 * 4)

(12 * 7) + 12

84 + 12

96 cubic meters

Now, I'll do the math to see which one of the remaining choices equals 96.

(4 * 6 * 7) + (3 * 3) = (24 * 7) + 9 = 168 * 9 = 177 cubic meters (X)

(4 * 7) + (4 * 3 * 6) = 28 + (12 * 6) = 28 + 72 = 100 cubic meters (X)

(4 * 6) + (4 * 6 * 3) = 24 + (24 * 3) = 24 = 72 = 96 cubic meters (✓)

(4 * 6 * 3) + (7 * 3 * 3) = (24 * 3) + (21 * 3) = 72 + 63 = 135 cubic meters (X)

With the problem solved, A & D are the answers to this question.

Your answer would be C

Answer:

Step-by-step explanation:

1. A right angle has a measure of 90°. The whole is the sum of the parts.

  (2x +3)° +49° = 90°

  2x +52 = 90 . . . . . . . . divide by °, collect terms

  2x = 38 . . . . . . . . . . . . subtract 52

  x = 19 . . . . . . . . divide by 2

2. A linear pair measures 180°. The whole is the sum of the parts.

  (x -5)° +151° = 180°

  x +146 = 180 . . . . . . . divide by °, collect terms

  x = 34 . . . . . . . . .subtract 146

3. We presume this pair of angles is supposed to be supplementary. That is, their sum is 180°.

  64° +(3x -1)° = 180°

  3x +63 = 180 . . . . . . . divide by °, collect terms

  3x = 117 . . . . . . . . subtract 63

Answer:

Your answer is A.

Step-by-step explanation:

When finding the area, you multiply π (3.14) and the radius (r). Then, you square the product (x2).

So, it is A = πr2

Answer:

B. 4 ft

Step-by-step explanation:

First, find the width of the wall.

The length, width, and diagonal form a right triangle, where the diagonal is the hypotenuse and the length and width are the 2 legs.

Use the pythagorean theorem and solve for a, the width of the wall.

a² + b² = c²

a² + 16² = 20²

a² + 256 = 400

a² = 144

a = 12

So, the width of the wall is 12 feet.

Solve for the width of the mural. Again, the diagonal, length, and width form a right triangle.

Use the pythagorean theorem again and solve for a, the width of the mural:

a² + b² = c²

a² + 6² = 10²

a² + 36 = 100

a² = 64

a = 8

So, the width of the mural is 8 feet.

Now, find the difference between the widths of the wall and mural:

12 - 8

= 4

So, the difference between the two widths is B. 4 ft

Answer:

The answer is  30 m²

Step-by-step explanation:

step 1

find the area of the first cross section

area1=b1*h/2

b1=8 m

h=10 m

area1=6*10/2------> 30 m²

step 2

find the area of the second cross section

area 2=b2*h/2

b2=12 m

h=10 m

area1=12*10/2------> 60 m²

step 3

find the difference in the areas of the cross sections

difference=60-30------> 30 m²

Answer:

Maybe 44

Step-by-step explanation:

This question is confusing but I'll try...

1- SInce Maddie already had 50$ from 270$, we have to minus 270$ from 50$: 270 - 50 = 220$

2- Then Maddie worked for 5 days so: 270$ - 5 days = 44
