Answer:

72

Step-by-step explanation:

Formula: A= 3.14r^2

4069.44^2 = 3.14r^2

(divide both sides by 3.14)

1296=r^2

(find sqr root of 1296)

36=r

to find the diameter with the radius, multiply radius by 2... 36*2= 72

The diameter of a pond with an area of 4069.44^2 is 72!

Answer:

x = 35°

Step-by-step explanation:

A flat line = 180°

Knowing that, we can make an equation:

3x + 75 = 180

Now, solve:

3x + 75 = 180

    -  75   - 75

3x = 105

x = 35

Hope this helps :)

Answer:x=35

Step-by-step explanation:180-75=105

105/3=35

Answer:

1380 children and 820 adults went to the zoo that day

Step-by-step explanation:

System of Equations

Define the following variables

x = number of children that went to the zoo

y = number of adults that went to the zoo

On a certain day,  2000 people went to the zoo, thus:

x + y = 2000

Solving for x:

x = 2000 - y        [1]

The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:

1.50x + 4y = 5050       [2]

Substituting x from [1]:

1.50(2000 - y) + 4y = 5050

Operating:

3000 - 1.50y + 4y = 5050

3000 + 2.5y = 5050

Subtracting 3000

2.5y = 5050 - 3000 = 2050

Dividing by 2.5

y = 820

From [1]

x = 2200 - 820 = 1380

1380 children and 820 adults went to the zoo that day

Answer:

(-2,1)

Step-by-step explanation:

Substitute the value of y (x+3) from one equation into the second equation (2x+5)

X+3 = 2x + 5

add -2x to both sides

-x+3=5

add -3 to both sides

-x=2

x=-2

substitute -2 for x in either equation to find y.

y=-2+3

y=1

Check your answer by substituting x and y into either equat to make sure it equals.

y=x+3

1=-2+3

1=1

or

y=2x+5

1=2(-2)+5

1=-4+5

1=1

The expression 42+24n in factor form is  6(7+4n).

An expression is combination of variables, numbers and operators.

The given expression is 42+24n

Forty two plus twenty four n.

We need to factor out the expression.

TO do this we have to find the greatest common factor of 42 and 24

The factor of 42 are 1, 2, 3, 6, 7, 14, 21 and 42

The factors of 24 are  1, 2, 3, 4, 6, 8, 12 and 24.

The common factors are 1,2,3, and 6.

The greatest common factor is 6.

S0 the expression in factor form is  6(7+4n)

Hence, the expression 42+24n in factor form is  6(7+4n).

Complete Question:

The amount of money, y, pizzeria W makes by selling x pizzas can be modeled by the equation y = 15x. The relationship of the amount of money pizzeria L makes is shown in the following graph.

Which pizzeria makes more money per pizza?

A. Pizzeria L makes more money per pizza.

B. Pizzeria W makes more money per pizza.

C. They make the same amount per pizza.

Answer:

B. Pizzeria W makes more money per pizza.

Step-by-step explanation:

The proportional relationship showing how amount of money made(y) is related to the amount of pizzas sold (x) for pizzeria W is given by the equation y = 15x.

the constant of proportionality/unit rate, k = 15.

This represents the amount in dollars, made per pizza.

So, Pizzeria W makes $15 per pizza.

For Pizzeria L, using any point on the line, say, (2, 24),

k = y/x = 24/2 = 12.

This represents the unit rate, which is the amount Pizzeria L makes per pizza.

Thus, Pizzeria L makes $12 per pizza.

We can conclude that, Pizzeria W makes more money per pizza.

Answer:

C

Step-by-step explanation:

From the given frequency table,

Frequency represents the number of people who made the calls.

Total number of people who made the calls = 16 + 11 + 5 + 3 + 1

                                                                          = 36

Number of people who made less than 13 calls = 16 + 11 + 5

                                                                                 = 32

Number of people who made at least 9 calls = 5 + 3 + 1

                                                                            = 9

Percentage of people who made at least 9 calls = [tex]\frac{\text{Number of people who made at least 9 calls}}{\text{Number of people who made the calls}}\times 100[/tex]

= [tex]\frac{9}{36}\times 100[/tex]

= 25%

Difference in the number of people who made the calls between 5-8 calls than 13-16 calls = 11 - 3 = 8

Answer:

21%

Step-by-step explanation:

Another 10% increased means it becomes 110*110/100 = 121. The first 10% increase means the second 10% increase will be an actual 11% increase from the original, so it will be a total of 21%.

Answer:

Step-by-step explanation:

Because the first 10% increase is calculated as 10% of what you started with. The second 10% is 10% of what you started with plus 10% of the increase caused by the original 10% increase.

Let's do the maths…

Let's start with 100 to make things easy.

We know that 10% of 100 is 10.

We know that 20% of 100 is 20.

So if we increase 100 by 10% we get 110.

If we increase 100 by 20% we get 120.

Now lets do the 10% plus 10%.

From the first 10% increase we were left with 110.

Now if we take 10% of the 110 we have 11.

Add that to the 110 and we get 121.

This is why people are surprised how quick a lone can rise if we don't pay it off. We are paying interest on the basic sum plus interest on the interest, then interest on the interest on the interest.
