If the area of a circle is 25pi (n), what is the radius of the circle
Answer:
5
Step-by-step explanation:
the are is pi times radius times radius
so do the square root of 25, which is 5.
this means that the radius is 5
Answer:
five (5).
Step-by-step explanation:
Area of circle =pi r^2
given that area is 25pi
now equate both .....we get
25pi=pi r^2
25=r^2
r=5

Which of the following would be a possible solution to the system of inequalities given below?
(3,-3)
(1,-7)
(6,4)
(-5,0)
Answer:
(3, -3)
Step-by-step explanation:
A point qualifies as a solution to a system of inequalities if it is true when both of its x and y values are substituted into the both inequalities. Knowing this, let's plug in the first option, (3, -3), into both inequalities.
Let's try 6x + 3y > 3 first. Substitute 3 for x and -3 for y:
[tex]6 (3) + 3 (-3) > 3\\18 - 9 > 3\\9 > 3[/tex]
9 is bigger than 3, so (3, -3) is a solution to that inequality.
Let's try [tex]x -y \geq 4[/tex]. Do the same, substituting the same values:
[tex]3 - (-3) \geq 4\\3 + 3 \geq 4\\6\geq 4[/tex]
6 is bigger than 4, so (3, -3) is a solution to that inequality too.
Since (3, -3) is a solution to both inequalities, it must be the answer.
the spinner below is spun then the a month of the year is randomly selected. Find each probability

I think the answer is 0.3
Step-by-step explanation:
Sorry if am wrong.
Answer:
Step-by-step explanation:
P (blue) fraction = 2/8 decimal=.25 percent=25%
P(purple) fraction=0/8 decimal=0 percent =0%
P(not green) fraction=5/8 decimal=.625 percent= 62.5%
P(not brown) fraction=8/8 decimal=1 percent =100%
2)Refer to the table on air travel selected airports. Suppose a flight that arrived at El Centro is selected at random. What is the probability that the flight did not arrive on time? write your answer as a fraction, decimal and percent.
80% on time so 20% are not on time
20/100 ÷ 20 =1/5
20%, .2, 1/5

How can you write the equation for a linear function if you know only two ordered pairs for the function? Drag tiles tho complete the explanation. Tiles may be used once, more than once, or not at all.
Answer:
Explanation below
Step-by-step explanation:
First determine the slope using (y2-y1)/(x2-x1)
Then set up point slope form and add in an ordered pair for x and y to determine the y intercept: y - y1 = m(x - x1). Solve for y and you'll end up with slope intercept form.
For example: (-2,1), (3,2) find slope and y intercept.
(2-1)/(3-(-2))= 1/5
y-2=.2(x-3)
y=.2x-.6+2
y=.2x+1.4 or y=(x/5)+(7/5)

Step-by-step explanation:
Robert is pouring wax into cylindrical candle containers. Approximately 226.19 cubic inches of wax fill one candle jar. Which image represents that volume?
A cylinder with height 8 inches and radius 3 inches.
A cylinder with height 5 inches and radius 4 inches.
A cylinder with height 10 inches and radius 2 inches.
A cylinder with height 5 inches and radius 5 inches.
Answer:
The first choice.
Step-by-step explanation:
The volume must be about 226.19 in^3.
Volume of a cylinder = area of base * height4
= πr^2h = 226.19
r^2 = 226.19 / πh.
Consider the first of the choices:-
When h = 8 , r^2 = 226.19 /8π = 8.9998
So r = 3.00 to nearest hundredth.
So this is the required image.

A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?
A. 3,807 mph
B. 1,266 mph
C. 432 mph
D. 423 mph
Answer:
423 mph
Step-by-step explanation:
To find the answer, you have to divide 1,269 by 3 since we want to find how many miles the plane travels in one hour. Doing this, we end up with 423 which is the answer.
Step-by-step explanation:
A nonstop flight from Albuquerque, NM to Atlanta, GA takes 3 hours. If the plane flies a total of 1,269 miles, what is the plane’s unit rate in miles per hour?

Paul has $145 in his savings account. He earns $36 a week mowing lawns. If Paul saves all of his earnings, after how many weeks will he have no more than $450 saved?
Answer:
Paul will have no more than $ 450 in next 8 weeks.
Step-by-step explanation:
From the information given on statement, we know that Paul saves all of his earnings weekly. Then, the money save is equal to the sum of initial amount ([tex]C_{o}[/tex]), measured in monetary units, and week earning ([tex]R[/tex]), measured in monetary units, multiplied by a number of weeks ([tex]n[/tex]), dimensionless:
[tex]C =C_{o} + n\cdot R[/tex] (1)
Now we clear the number of weeks within the formula:
[tex]n = \frac{C-C_{o}}{R}[/tex]
If we know that [tex]C_{o} = \$\,145[/tex], [tex]C = \$\,450[/tex] and [tex]R = \$\,36[/tex], then the number of weeks is:
[tex]n = \frac{\$\,450-\$\,145}{\$\,36}[/tex]
[tex]n = 8.472[/tex]
Paul will have no more than $ 450 in next 8 weeks.
Answer:
Paul will have no more than $ 450 in next 8 weeks.

Brian spends the same amount of money each morning. On Saturday he bought a large coffee for $1.25 and 2 doughnuts. On Sunday he brought a small coffee for $.50 and 5 doughnuts. Write and solve an equation to determine the cost of one doughnut.
Answer:
Cost of one doughnut is $0.25
Step-by-step explanation:
Let the rate of one doughnut = $x
On Saturday he bought a large coffee and 2 doughnuts.
Cost of one large coffee = $1.25
Cost of 2 doughnuts = $2x
Total cost = $(1.25 + 2x)
On Sunday, he bought a small coffee and 5 doughnuts.
Cost of one small coffee = $0.50
Cost of 5 doughnuts = $5x
Total cost = $(0.50 + 5x)
Since, Brian spent same amount of money each morning,
Total expenditure on Saturday morning = Total expenditure on Sunday morning
(1.25 + 2x) = (0.50 + 5x)
1.25 - 0.50 = 5x - 2x
0.75 = 3x
x = $0.25
Therefore, cost of one doughnut is $0.25

A car dealership's annual sales report shows 768 vehicles were sold last year. The report revealed that 48 out of every 64 vehicles sold were SUVs. Based on the results of the report, how many of the vehicles sold were not SUVs?
Answer:
[tex]Others = 192[/tex]
Step-by-step explanation:
Given
[tex]Vehicles = 768[/tex]
[tex]SUV = \frac{48}{64}[/tex] --- Proportion of SUV
Required
Determine the number of vehicles that are not SUV
First, we calculate the number of SUV by:
[tex]SUVs= Proportion * Total\ Vehicles[/tex]
[tex]SUVs= \frac{48}{64} * 768[/tex]
[tex]SUVs= \frac{3}{4} * 768[/tex]
[tex]SUVs= \frac{3* 768}{4}[/tex]
[tex]SUVs= \frac{2304}{4}[/tex]
[tex]SUVs= 576[/tex]
Vehicles that are not SUVs is then calculated as:
[tex]Others = Total - SUVs[/tex]
[tex]Others = 768 - 576[/tex]
[tex]Others = 192[/tex]
