Answers

Answer:

Step-by-step explanation:

13+9=22

6446 ÷ 22 = 293

293 X 13 = 3808

Answer: 3809

Step-by-step explanation:

Votes of scary mary-lou = 13x

Votes of silly billy-boo = 9x

Total votes = 6446

Now, 13x + 9x = 6446

22x = 6446

x = 293

Hence, Votes of Scary... = 13*293 = 3,809

During soccer practice, the goalie blocked 72% of the shots attempted by the opponents. If the goalie blocked a total of 18 shots, how many total shots were attempted?

Answers

Answer: 25

Step-by-step explanation:

1. Calculate the percentage of shots attempted by the opponents: 72%

2. Convert percentage to a decimal: 0.72

3. Multiply the decimal by the number of shots blocked (18): 0.72 * 18 = 12.96

4. Divide the number of shots blocked (18) by the decimal: 18 / 0.72 = 25

Therefore, a total of 25 shots were attempted.

In a bag of marbles, the ratio of the number of blue to red to white is 13:2:6. If the number of blue marbles minus the number of white marbles is 21, how many red marbles are there?

Answers

Answer: There are 6 red marbles

Step-by-step explanation:

13 - 6 = 7

21/7 = 3

3 x 2 = 6

To check the answer:

13 x 3 = 39

6 x 3 = 18

39 - 18 = 21

Answer:

6

Step-by-step explanation:

Blue = 13x

Red = 2x

White = 6x

Now, they have given one more info:

Blue - White = 21

So, 13x - 6x = 21

7x = 21

x = 3

∴ Now, Blue = 13*3 = 39

Red = 2*3 = 6

White = 6*3 = 18

Total = 63

What is the circumference of a circle with a radius of 11 cm? (Use pi = 3.24)
Circumference = 2piR

Answers

Answer:

Step-by-step explanation:

C = 2 x 3.24 x 11

C = 71.28

A = piR^2

A = 3.24 x 11^2

A = 392.04

Pi is supposed to be 3.14 but since your problem says to use 3.24, we will use that.


The answer is 71.28




Circumference = 2piR

Substitute the values.

Circumference = 2(3.24)(11)

Circumference = 6.48(11)

Circumference = 71.28

Solve the system of linear equations by substitution
5y=10
x-3y=4

Answers

Step-by-step explanation:

To solve the system of linear equations by substitution, we'll use the equation 5y = 10 to solve for y. We'll substitute this value of y into the second equation to get an equation in terms of x. Then, we'll solve for x and substitute the value of x back into one of the equations to find y.

Starting with the first equation:

5y = 10

y = 2

Next, we'll substitute this value of y into the second equation:

x - 3y = 4

x - 3(2) = 4

x - 6 = 4

x = 10

Now that we have found x, we can substitute it back into one of the equations to find y:

5y = 10

y = 2

So the solution to the system of linear equations is (x, y) = (10, 2).

Answer: (x, y) = (10 , 2)

Step-by-step explanation: 1. Solve the equation for y: {y=2

                                                                                            {x-3y=4

2. Substitute the given value of y into the equation x-3y=4: x-3x2=4

3. Solve the equation for x: x=10

4. The possible solution of the system is the ordered pair (x, y): (x, y)=(10, 2)

5. Check if the given ordered pair is the solution of the system of equations: {5x2=10

                  {10-3x2=4

6. Simplify the equalities: {10=10

                                             {4=4

7. Since all of the equalities are true, the ordered pair is the solution of the system. --> (x, y)=(10, 2)

So then, in conclusion, the solution must be, (x, y)=(10, 2).

Delancey plans to run at least three miles each week for her health. Delancey has a circular route in the neighborhood to run. Once around that route is 220 yd. If Delancey runs that route 40 times during the week, will she cover at least 3 mi explain

Answers

Answer: Yes

Step-by-step explanation:

Since she wants to run the route 40 times we have to multiply the 220 yd route with how many times she wants to run it

40 x 220 = 8800 which is 5 miles

She reaches her goal and beyond that

Yes, because if you multiply 220 by 40, you will get 8,800, which is 5 miles.
