I'm super confused about this

Answer:

The area is approximately 201.06

Step-by-step explanation:

If you use the equation pi r^2, then we will get the answer. Since the diameter is double the radius, we should know that the radius is 8ft. Then we do the math and get the answer above.

Answer: A≈201.06ft²

Step-by-step explanation:

How to Calculate Diameter?

Diameter = Circumference ÷ π (when the circumference is given)

Diameter = 2 × Radius (when the radius is given)

Diameter = 2√[Area/π] (when the area is given)

The time for 22 leg-press reps is 11.9 seconds.

The lines of best fit is the trend line of the dataset.

The table is given as —

(x) : 12 32 7 26 28 15 1

(y) : 8.6 14.6 7.1 8.3 11.9 19.4 9.5

To determine the equation of line of best fit, we make use of a regression calculator.

Enter the above dataset in a regression calculator, the equation is: y = 0.120x + 9.274 (Approximated to Three Decimal Places / Rounded of to the Thousandths Place)

This means that x = 22.

So, we have:

y = 0.120 * 22 + 9.274

  = 2.640 + 9.274

  = 11.914

(Approximate to the nearest hundredths)

  = 11.9

Hence, the time for 22 leg-press reps is 11.9 seconds.

Hope my answer helps you.

Step-by-step explanation:

the answer to your question is c

Answer:

#5 = option a (129.38 miles):

We are told that the cities are 17.25 inches apart, and that 2 inches equal 15 miles. First we have to divide 17.25 inches by 2 we end up with 8.62500 inches (not simplified yet). Next, we just take 8.62500 inches and multiply that with 15, which leaves us with 129.37500 inches. Then we just round that to the nearest hundredth which will give us 129.38 inches which means 129.38 miles as well!

#2 = option a (2.4 inches)

We know that bigger rectangle's length is 16 inch and that smaller rectangle's length is 3.2 inches. We just have to calculate the decrease of the length and we do that by dividing. We have to do 16 inches divided by 3.2 inches which equals 5. (You can double check that by multiplying 3.2 inches by 5 which would equal 16 inches) Now to find the width of the smaller rectangle, we just have to divide the width of the bigger rectangle, which is 12 inches, by 5 which would give us 2.4 inches!

#4 = ?

#6 = option c (7.2cm)

So basically I just did 25cm divided by 10cm which equals 2.5cm. (You can also do 25cm divided by 2.5cm to get 10cm if you want to double check). Then I just did 18cm divided by 2.5 cm which led me to the answer 7.2cm)

#3 = ?

Answer: A

Step-by-step explanation: 17.25/2=8.652

8.652*15=129...

rounded it would be equivalent to answer choice A.

Answer:

1. a. draw 5 boxes with 7ś in them and x=7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

Step-by-step explanation:

1. the value of x is seven because 5x = 35 divide x on both sides is 7

2. number 7. x+x+x=9 that is A. and x+3=9 for B.

3. part a: x+9=16 draw a box with x+9=16 and x=7

3. part b: 4(x)=28 draw a bout that matches that and x=7

Answer:

We can use the given information to set up a system of two equations:

c = 13g + 20

c - 13g = 20

The second equation is obtained from the first equation by subtracting 13g from both sides.

To solve this system, we can use substitution.

First, we solve the second equation for c.

c = 20 + 13g

Then, we substitute this expression for c into the first equation.

20 + 13g = 13g + 20

Then, we simplify.

20 = 20

So, the value of c when g = 9 is 20 + 13 * 9 = 20 + 117 = 137.

Check:

200*0.85 = 170

Answer: hope this helps ♡

200 tickets were originally put up for sale.

Step-by-step explanation:

85% = 170

(we divide 85 and 170 by 85)

1% = 2

(now multiply 1 and 2 by 100)

100% = 200

(double check: 85% from 200 → (85×200) ÷ 100 = 170 ✓)

Answer: Ratios form a proportion if they are equal when cross-multiplied.

1/4 and 3/12

Cross-multiply these ratios to compare them: 1/4 * 12 = 3, 3/12 * 4 = 3.

So they are equal and form a proportion.

54/10; 81/15

Cross-multiply these ratios to compare them: 54/10 * 15 = 81, 81/15 * 10 = 54.

So they are equal and form a proportion.

18/24; 15/20

Cross-multiply these ratios to compare them: 18/24 * 20 = 15, 15/20 * 24 = 18.

So they are equal and form a proportion.

Hence, all the ratios mentioned above form a proportion.
