Answer:
Circumference= 84.78 or if needed simplified 85
Step-by-step explanation:
c=2×3.14×r
in this case to get the radius divide the diameter by 2 which would equal 13.5 so the formula would be
2×3.14×13.5=84.78

1). what is the area of the rectangle whose length is (x+5) and width (x-5)?
Answer:
[tex]x^{2}[/tex]-25
Step-by-step explanation:
formula for areas of rectangles= width x height
width=x-5
height=x+5
(x-5)(x+5)= [tex]x^{2}[/tex]-5x+5x-25
since the 5x's cancel out each other
=[tex]x^{2}[/tex]-25 will be the answer
The area of rectangle is [tex](x^{2} -25)[/tex] unit square.
The area of rectangle is product of length and width.
[tex]Area = length*width[/tex]
Given that length is [tex](x+5)[/tex] and width is [tex](x-5)[/tex].
[tex]Area=(x+5)*(x-5)\\\\Area=x^{2} -5x+5x-25=x^{2} -25[/tex]
Hence, the area of rectangle is [tex](x^{2} -25)[/tex] unit square.

Bob's linear speed is higher than Jack's because the radius of the circle
around which Bob rotates is larger.
Responses:
Jack's linear speed is approximately 377 feet per minuteBob's linear speed is approximately 527.8 feet per minuteWhat is the relationship between linear speed and angular speed?Given:
The rotational speed of the merry go round = 6 revolution per minute
Jack's distance from the center = 10 feet
Bob's distance from the center = 14 feet
The angular speed, ω, of the merry-go-round is found as follows;
[tex]\omega = \mathbf{\dfrac{6 \times 2 \cdot \pi}{1 \ minute}} = 12 \cdot \pi \ rad/minute[/tex]Linear speed = ω × rWhich gives;

Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits.
if Carlos pays $85 in the last month how many times did he visit the gym?
Answer:
25 times
Step-by-step explanation:
To find how many times he visited, plug in 85 as y and solve for x:
y = 3x + 10
85 = 3x + 10
75 = 3x
25 = x
So, Carlos visited the gym 25 times

Use the table below to determine whether f(x) could represent a linear function. If it could write f(x) in the form f(x) = mx +b.
Answer:
5x-3
Step-by-step explanation:
This is linear because the numbers are changing at a constant rate (of 5)
We can also see that when x=0 y= -3 which means that in our equation
y=mx+b
-3 =b
I said prior that the rate of change is 5 which means that our slope is 5
which means that our equation looks like
5x-3

Answer:
only Katie is right
Step-by-step explanation:
first, find the nth rule using the equation n = a + (n - 1)d
a = first term (here, it's 22)
n = the position of a term
d = the constant difference between each term (here, it's -5 since each term reduces by 5)
put these in and then simplify:
n = a + (n - 1)d
n = 22 + (n - 1)(-5)
n = 22 - 5n + 5
n = -5n + 27
this can be rewritten as n = 27 - 5n, which means therefore that only Katie is right. hope this helps!
Answer: Only Katie

Answer: No, the scenario won't earn you enough money
====================================================
Explanation:
You work 4 hours with your uncle, at $8 an hour, so that means you earn 4*8 = 32 dollars.
You work 12 hours online, at $4 an hour, so you earn 12*4 = 48 dollars.
In total, you earn 32+48 = 80 dollars overall when combining the two lines of work.
The total 80 is smaller than 120, so this scenario isn't possible if you want to aim for $120 or more. You'll need to work more hours somehow.

Find the missing length.
Answer:
Triangle 1 - 4
Triangle 2 - 10
Step-by-step explanation:
To find the missing side lengths of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem states that: a² + b² = c². In this equation, a and b are legs, and c is the hypotenuse.
Using this to solve triangle 1, you get the equation: a² + 3² = 5² or a² + 9 = 25. To solve for a², you subtract 9 from both sides to get a² = 16. To solve for a, find the square root of 16, which is 4.
Using the Pythagorean Theorem to solve for triangle 2, you get the equation: 6² + 8² = c² or 36 + 64 = c². Add 36 + 64 to get 100 = c². Find the square root of 100 to solve for c. The square root is 10.
