A. m=50
B. p=50m
C. m=50p
D. m= p/50

Answers

Answer:

Option C: m=50p is the correct answer.

Step-by-step explanation:

Given that:

Amount received per player = $50

Let,

m represent the amount of money each team is given.

p represent the number of players on the team

Amount of money = Amount received per player * Number of players

m = 50p

A spotlight can be adjusted to effectively light a circular area of up to 7
meters in diameter. What is the maximum number of square meters
that can be effectively lit by the spotlight?
(Draw a circle with a diameter of 7 meters, then solve.)

Answers

Answer:

38 square meters

Step-by-step explanation:

Use the circle area formula:

A = πr² = πd²/4

Substitute the value of the diameter and calculate:

A = 3.14*7²/4A = 38.465 m²

Maximum number of  square meters is 38

Answer:

Diameter of the spotlight is 7 meters

Radius=Diameter/2=7/2 meters=3.5 meters

Area of the circular spotlight is :---

π×(radius)² =22/7×3.5×3.5=38.5 meter²

The maximum number of square meters that can be effectively lit up by the spotlight is 38.5 square meters.

The area of a circle is 9π
if and only if, its radius is 3.

What is the first step you would take to solve the equation 5x - 12 = -20?


Divide 5x and -20 by 5.


Add 20 to both sides.


multiply 12 by .


Add 12 to both sides.

Answers

Answer:

The first step would be to add twelve to both sides

Step-by-step explanation:

Answer:

add 12 to both sides

Step-by-step explanation:

What we want to do, is to isolate the variable and the numbers on different sides.

if we divide 5x and -20 by 5, what about -12? It's part of the equation too.

If we add 20 to both sides, the numbers and the variable are on the same side, so we'll need to subtract it back off to isolate both.

If we multiply 12 by (what was there) it won't be isolating the variable or numbers. We'll just be increasing the value of the terms already there.

However, if we add 12 to both sides, we'll be isolating both the variable AND the numbers onto different sides.

therefore, add 12 to both sides.

Answers

Answer:

The total number of cookies they baked altogether is 216 cookies

Step-by-step explanation:

Here, we want to know the number of cookies that they baked together

From the question, we are told that Clementine baked 72 cookies while Jake baked twice as much

what this mean is that the number of cookies baked by Jake will be (2 * 72) = 144 cookies

Thus, the total number of cookies baked by the two of them will be;

72 + 144 = 216 cookies

Aliyah is drawing a ball from one bag and a tile from another bag the first bag contains four green balls and four yellow balls the second bag contains tiles 1 through 5 search

Answers

Complete question :

Aliyah is drawing a ball from one bag and a tile from another bag the first bag contains four green balls and four yellow balls the second bag contains tiles 1 through 5 search

What is the probability that she draws a green ball and a tile numbered with 4?

Answer:

1 / 10

Step-by-step explanation:

Given:

Bag content :

Green balls = 4

Yellow balls = 4

Probability = required outcome / Total possible outcomes

P(drawing a green ball) = 4 / 8 = 1/2

Total number of tiles = 5

P(drawing tile numbered 4) = (number of tiles numbered 4 / total number of tiles) = 1 / 5

P(drawing a green ball) * P(drawing tile numbered 4)

= 1 / 2 * 1 /5

= 1 / 10
