Answer:

to find the sons shadow you would simply multiply the length of his body by 2, therefore his shadow would be 2 meters long

The height of shadow is 2 meter long.

We have,

The father is 2 meters tall and casts a shadow 4 meters long.

let the length of shadow be x.

Using proportion

2/4 = 1/ x

2x = 4

x =4 /2

x = 2 meter

Thus, the height is 2 meter tall.

Answer:

19

Step-by-step explanation:

if you do the checker method then you would find that

they add up to make a line which equals 180

so... the equation is (8x-7)+(x+16)=180

do the math and x=19

Answer:

x + 110 + 47 = 180

x = 180 - 157

x = 23

Answer:

2.215=2 43/200

Step-by-step explanation:

Showing the work

Rewrite the decimal number as a fraction with 1 in the denominator

2.215=2.215/1

Multiply to remove 3 decimal places. Here, you multiply top and bottom by 103 = 1000

2.215/1×1000/1000=2215/1000

Find the Greatest Common Factor (GCF) of 2215 and 1000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 5,

2215÷5/1000÷5=443/200

Simplify the improper fraction,

=2 43/200

In conclusion,

2.215=2 43/200

Answer:

[tex]\frac{731}{330}[/tex]

Step-by-step explanation:

We require 2 equations with the repeating numbers placed after the decimal point.

let x = 2.2151515... ( multiply both sides by 10 and 1000 )

10x = 22.1515.... → (1)

1000x = 2215.1515.... → (2)

Subtract (1) from (2) thus eliminating the repeating decimal

990x = 2193 ( divide both sides by 990 )

x = [tex]\frac{2193}{990}[/tex] = [tex]\frac{731}{330}[/tex]

Thus

2.2151515..... = [tex]\frac{731}{330}[/tex]

Answer:

A

Step-by-step explanation:

To find the perpendicular line you need to find the negative reciprocal of 4/7x which is -7/4x, so A is the correct answer

I hope this helps!!

Answer:

No.

Step-by-step explanation:

We substitute the values x = 2 and y = -4 into the inequality.

Left side = 2(2) - 3(-4) = 4 + 12

= 16

Now the right side is 15 so we get 16 < 15 which is incorrect.

So (2, -4) is not a solution.

Answer:

21 consonant tiles

Step-by-step explanation:

Henry has a bag containing 39 letter tiles, some consonants, and some vowels.

He selects a tile without looking and then replaces it. If he pulls 7 consonant tiles and 6 vowel tiles, which is the most likely number of consonant tiles in Henry's bag?

Step 1

We add up the number of tiles that he pulls out of the bag

= 7 consonant tiles + 6 vowel tiles

= 13 tiles

Step 2

We divide the total number of tiles in the bag by the total number of tiles that was pulled out of the bag

= 39 tiles ÷ 13 tiles

= 3

Step 3

The most likely number of consonant tiles in Henry's bag is calculated as:

3 × The number of consonant tiles that was pulled out of the bag.

Hence:

3 × 7 consonant tiles

= 21 consonant tiles.

Therefore, the most likely number of consonant tiles in Henry's bag is 21 consonant tiles.

Answer:

1/4 of 2 hours

Step-by-step explanation:

30 min + 30 min = 1 hour. 1 hour is one half of two hours. Therefore, 30 minutes is 1/4 of 2 hours

Answer:

sum of exterior angles of a polygon = 360°

therefore,

x + 5 + x + 10 + 3x - 8 + 5x + 10 = 360°

10x + 17 = 360°

x + 17 = 360 ÷ 10 = 36

x = 36 - 17 = 19

x = 19

value of x will be 20

Answer:

Let's define the variable x as the number of apples in each bag.

We know that she bought 4 bags, then the total number of apples that she has is:

Apples = 4*x

Now she eats one apple for each bag, then she eats 4 apples, so she now has:

Apples = 4*x - 4

And we know that this is equal to 28, then:

4*x - 4 = 28

now we can solve this for x.

4*x = 28 + 4 = 32

x = 32/4 = 8

x = 8

There are 8 apples in each bag.

For the diagram part, by a small online search y found the image that you can see below.

The diagram that correctly represents this situation is diagram C, where x represents the number of apples in each bag.

10 - 10 x 10  

10 x -10 = -100   (always do multiplication first)

-100 + 10 = -90

Answer: The answer to this basic math question with a basic given math expression is -90.

Step-by-step explanation: Mmmm, that was super extremely easy, so anyways, here are 3 basic steps in order to evaluate the given basic math expression:

Step 1. First, let's input the original basic equation that looks in the basic equation form like this: [tex]10 - 10 * 10.[/tex]

Step 2. After we input the original basic equation, next, let's do the multiplication first by multiplying 10 by 10 that looks in the basic equation form like this: [tex]10 - 100.[/tex]

Step 3. Last but not least is after we multiply 10 by 10 first, finally, let's subtract 10 and 100, and therefore your answer to this basic math question with the given basic math expression is -90.

I hope that my full given answer with my full given step-by-step explanation is very helpful to your own basic math question with the given basic math expression, please take care, always be safe, and have a great rest of the holiday winter break, Merry Christmas and a happy new year! :D

Answer:

1. The y-intercept 8 means you start off with $8. The slope 1/4 means how much money you have to pay for the amount of tickets purchased for carnival games.

2. The y-intercept 2 means the number of chapters you started reading and the slope 5/4 means the number of chapters you read per day.

3. The y-intercept 3 means the inital (start) cost of a muffin delivery and the slope 2 means the cost of each muffin delivery for the number of muffins you ordered.

Number 3 on the slope part might be the other way around if I'm wrong :)
