The value of the variable x will be 2. Then the radius of the circle will be 5.
What is the area of a circle?Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The radius of the circle is x + 3. And the area of the circle is 25π. Then the equation will be
25π = π(x + 3)²
(x + 3)² = 25
x + 3 = 5
x = 5 - 3
x = 2
Then the radius will be
r = x + 3 = 2 + 3 = 5
The value of the variable x will be 2. Then the radius of the circle will be 5.

George is 3 years older than the quotient of Joseph's age and 2. Letj represent joseph's age. Write an expression in the box
that would show George's age
Answers
Answer:
j/2+3
Step-by-step explanation:
Joseph's age is unknown, so we will use j. It says the quotient of Joseph's age (j) and 2, so it would be j/2, or j divided by 2.
Then it says that George is 3 years older, so that would be addition.
Therefore, it would be:
x/2+3

Answers
Answer:
She rode 17.4 miles in 1 hour
Step-by-step explanation:
A cyclist rode for 3.5 hours and completed a distance of 60.9 miles. If she kept the same average speed for each hour, how far did she ride in 1 hour?
Part A Estimate the quotient. Include an equation to show your work. Explain your thinking.?
The quotient is the average speed and this is calculated as:
Speed = Distance(miles)/Time(hours)
Where speed = quotient
Distance = Dividend
Time = Divisor
Speed = 60.9 miles/3.5 hours
= 17.4 miles/hour
Part B Find the exact distance she rode in 1 hour by completing the division. PLEASE HELP!
If :
3.5 hours = 60.9 miles
1 hour = x miles
Cross Multiply =
3.5x = 60.9 miles
x = 60.9/3.5
x = 17.4 miles
Hence, she rode 17.4 miles in 1 hour

Step-by-step explanation:
-23 = 13w + 2w + 22

-45 = 15w
Divide both sides by 15
w = -3

What type of association is shown by the data in the scatter plot?
Answer Choices:
A. positive association
B. negative association
C. no association
D. trend association
Answers
=================================================
Explanation:
We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.
Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.
-----------------
Extra info:
Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points. The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.For any whole number b that is a PERFECT SQUARE

How do I solve for the missing angle?!
And please include explanations on how you got the answer
Answers
Answer:
75°
Step-by-step explanation:
In triangle FBG, one angle is 36. That means the other two must total 180-36=144. Assigning each one 72, their supplementary angle on the interior of the pentagon would be 108.
In triangle JDI, one angle is 39. That means the other two must total 180-39=141. Assigning each one 70.5, their supplementary angle on the interior of the pentagon would be 109.5
We now have 4 of the interior angles. Pentagons have an interior total of 540. 540-108-108-109.5-109.5=105
x is the supplement of 105. 180-105=75

Find V. 10 points plz.
Answers
Answer:
v = 60 yards
Step-by-step explanation:
In the similar triangles, their corresponding sides are proportional which means they have equal ratios
In triangles IHG and FHJ
∵ Δ IHG ≈ FHJ
∵ Side IH is corresponding to side FH
∵ Side HG is corresponding to side HJ
∵ Side IG is corresponding to side FJ
→ Their ratios are equal
∴ [tex]\frac{IH}{FH}[/tex] = [tex]\frac{HG}{HJ}[/tex] = [tex]\frac{IG}{FJ}[/tex]
∵ IH = 54 yards and FH = 72 yards
∵ IG = v and FJ = 80 yards
→ Substitute them in the first and last ratios above
∴ [tex]\frac{54}{72}[/tex] = [tex]\frac{v}{80}[/tex]
→ By using cross multiplication
∴ v × 72 = 80 × 54
∴ 72v = 4320
→ Divide both sides by 72
∴ v = 60 yards
