Worth 20 Pts:There Are Many Cylinders With A Height Of 18 Meters. Let RRepresent The Radius In Meters

Answers

Answer 1

Answer: 18, 72, 288

Step-by-step explanation:

The formula for cylinder volume is V=π r^2 h

Substitute: radius =1 and height =18

V= 18 pi

radius=2

V=72 pi

radius=4

V= 288 pi

Of course, pi appears to already be written there for you :)

Hope this helps!

Chau is a software salesman. His base salary is $2300, and he makes an additional $50 for every copy of Math is Fun he sells.
Let P represent his total pay (in dollars), and let N represent the number of copies of Math is Fun he sells. Write an equation relating P to N. Then use this equation to find his total pay if he sells 26 copies of Math is Fun.

Answers

2300 + 50n = P

Sub 26 for n:

2300 + 50(26) = P
3600 = P

Answer: hope this helps ♡

P = $3600

Step-by-step explanation:

P = total pay

N = num of 'Math is Fun'

P = $2300 + $50(N)

P = $2300 + $50(26)

P = $2300 + $1300

P = $3600

Dillon walked around the rectangular field 3 times and covered a distance of 240m. Calculate the area of the field.

Answers

Answer:

80

Step-by-step explanation:

240÷3=80

16×5=80 so i think its 80

Answer: hope this helps ♡

The area of the field is 80m.

Step-by-step explanation:

3 times = 240m

1 time(s) = 80m          (area - we divided 240 and 3 by 3)

A = ɭ × w

A = 80

w = 16

ɭ = ?

ɭ = 80 ÷ 16 = 5

A = 16 × 5 = 80 ✓

Answers

Answer:26

Step-by-step explanation:Since angles 1 and 2 are supplementary, it follows that there sum is 180°.

On this note;

Sum of 1 and 2 is;

180 = 124 + (2x + 4)°

(2x + 4)° = 180 -124

2x = 56 -4

2x = 52

x = 26°.

The triangle shown on the coordinate grid is translated 6 units to the right and 3 units down.
Which would be the measure of an angle of the resulting triangle?
(ignore the answer i choose lol) but pls help me

Answers

Answer:

75°

Step-by-step explanation:

Even if a triangle is translated, the original shape stays the same.

So, to get the answer, first add the first two angles of the triangle:

60 + 45 = 105

Then, subtract from 180, because 180 is equaled to all the angles added up on any triangle:

180 - 105 = 75.

So, you get 75°.

Answers

Answer: The Constant of Proportionality is 506.

Step-by-step explanation:

At 1 hour the plane traveled 560 Miles and at the second hour it had traveled 1,120 miles.

560+560=1,120 and if you add 560 to 1,120 you will get 1,680 which is the distance traveled at 3 hours. Therefore the answer is 560.

Answers

Step-by-step explanation:

Since Elsa is running at 2 and Anna at 1.75, we can first subtract

2 - 1.75 = 0.25, meaning each second Else gains 0.25m

Now that Anna was given a 10m headstart, we can divide 10 by 0.25

10/0.25 = 40

Meaning it would take 40 seconds for Elsa to catch up

the answer is 40, enjoy lol

Answer: 10x = 4 is x = 0.4.

To solve the equation 10x = 4, we want to isolate the variable x on one side of the equation.

First, we divide both sides of the equation by 10:

10x / 10 = 4 / 10

Simplifying:

x = 0.4

Therefore, the solution to the equation 10x = 4 is x = 0.4.

First Question's Answer = 7 + A

Second Question's Answer = (2 x 5) x 7

Step-by-step explanation:

The commutative property of addition states that numbers can be added together in any order without changing the resulting sum.

Therefore, A + 7 = 7 + A

The associative property of multiplication states the way in which three or more terms are grouped does not change the product.

therefore, 2 x (5 x 7) = (2 x 5) x 7
