Ruby misses 10% of the free throws she attempts in a season. How many total free throws did she attempt if she missed 70?

Answers

Answer:

700

Step-by-step explanation:

70x10 = 700

The total number of free throws she attempted is 700.

What is a percentage?

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Missed free throws = 10%

Total free throws = 100%

10% = 70

Multiply 10 on both sides.

100% = 700

Thus,

Total free throws are 700.

What is the perimeter of a rectangle?

The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).

Given that, the perimeter of a rectangular pool is more than 62 meters.

Let the length of a rectangular pool be l.

The width is at least 10 meters less than the length.

w≤ l-10

So, 2(l+w)>62

2l+2w≥62

Therefore, option D is the correct answer.

Answers

Answer:

Look at the numerators, how do you change 90.6 to 22.65? You divide 90.6, but by what? So, we divide to get the number we divide by, which is 4.

90.6 divided by 22.65 = 4

Now, we do the same to the 12 2/5. Since we divided the top by 4, we'll divide 12 2/5 by 4 as well. Change 12 2/5 to a decimal and then divide to get the denominator of the second number.

12 2/5 divided by 4 = 3.1

So, 90.6/12 2/5 = 22.65/3.1

The cost of the family’s cell phone plan rose from $130 to $194 when they added a phone for their daughter. What was the percent of increase?

Answers

Answer:

49%

Step-by-step explanation:

Step one:

initial price=$130

final price=$194

Step two:

we know that the percent increase is given as

% increase= final-initial/initial

substituting we have

% increase= 194-130/130*100

% increase= 64/130*100

% increase= 0.49*100

% increase= 0.49*100= 49%

therefore the percent increase is 49%

Workweek hours= 40

Total salary per week= $653.6

First, we need to calculate the monetary value of an hour:

Earn per hour= total salary/number of hours

Earn per hour= 653.6 / 40

Earn per hour= $16.34

Solve by using the elimination method. Show your work.

Answers

Answer:

as the last two months have a few minutes in a factory and we have a few minutes away and will also send the

7x + 4y = 24
4x - 4y = 0

first thing we need to do is eliminate a variable by adding them together. 4y - 4y eliminates the y.

7x + 4y - 4y = 24
4x - 4y + 4y = 0

7x = 24
4x = 0

no we can add our x’s together since they are the same variable.

11x = 24

now we need to divide both sides by 11.

11x = 24
— —
11 11

x = 24
—
11

this is x. now we need to substitute x into our first equations.

4(24/11)-4y = 0

then solve the equation for y. y in this equation is y = 24/11.

possible ordered pair is (24/11, 24/11) but we need to substitute this ordered pair into our equations.

7(24/11) + 4(24/11) = 24
4(24/11) - 4(24/11)= 0

both of these equations are true, meaning that the ordered pair is correct.
