Answer:
A ≈ 81.487 in²
Step-by-step explanation:
You know that circumference is C = 2πr, where r is the radius.
So,
C = 2πr
32 = 2(3.14)r
r ≈ 5.093 in
We also know that the formula for the area of a circle is A = πr², so:
A = πr²
A = (3.14)(5.093)²
A ≈ 81.487 in²
Tony bought a computer. He paid $450.00 plus sales tax. The sales tax
was 6%. How much did he pay in sales tax?
Answer:
$27
Step-by-step explanation:
We have to find 6% of $450. We can make an expression and solve it:
6/100•450
We can cancel out factors now:
3/50•450
Now we'll cancel out 50 and 450:
3x9=$27
And that's your answer! Hope this helps =)
What does B equal? PLEASE ANSWER
Answer:
b=6
a=6
hypotenuse=6√ 2
Step-by-step explanation:
This is a 45, 45, 90 triangle. This means a=b and hypotenuse is equal to b times √ 2. This means that you have to divide the hypotenuse by √ 2 to get what b is equal to 6√ 2 divided by √ 2 is equal to 6. Therefore, b=6. Because b and a are equal, a is also equal to 6. Therefore, b=6, a=6.

In circle H with m ∠ G H J = 90 m∠GHJ=90 and G H = 20 GH=20 units, find the length of arc GJ. Round to the nearest hundredth.
Answer:
180
Step-by-step explanation:
length of arc GJ ≈ 31.42 units.
What is the arc of a circle?A circle's arc is a bent portion of the circle's circumference. Its perimeter is determined by its two ends and the area of the circle that lies in between them. An arc's length or the angle it makes with the circle's center can be used to measure it.
The formula L = θr states that the length of an arc is inversely proportional to the radius of the circle and the angle it subtends. L is the length of the arc, r is the radius of the circle and θ is the angle the arc subtends in radians.
To find the length of arc GJ, we first need to find the circumference of the circle.
The circumference of a circle is given by the formula:
C = 2πr
where C is the circumference, π is a constant approximately equal to 3.14, and r is the radius of the circle.
Since GH = 20 units and HJ is the radius of the circle, we have:
HJ = GH = 20 units
So the radius of the circle is 20 units.
The formula for the length of the arc is 2πr(θ/360)
Since the angle is given 90, the length of the arc:
2*π*20(90/360)
=10 π
Therefore, the length of arc GJ is 10π or 31.42 units.

month. Based on the inequality below, if she wants to profit at least $1,240, how much should she charge, b, per bracelet?
80b - $520 > $1,240
A. Priya needs to charge at most $19 per bracelet.
B. Priya needs to charge at least $22 per bracelet.
C. Priya needs to charge at most $22 per bracelet
D. Priya needs to charge at most $29 per bracelet.
Answer:
B
Step-by-step explanation:
Profit = total revenue - total cost
total revenue = 80 x b
total cost = 520
the profit has to be at least $1240
80 x 22 = 1760
1760 - 520 = 1240
b is correct

Rebecca asked the people in her homeroom class what their favorite type of pizza was. If 18
out of 25 people said pepperoni, how many people would you expect to choose pepperoni
out of 350 people?
Answer:
x = people who chose pepperoni = 252
Step-by-step explanation:
Number of people : people who chose pepperoni = 25 : 18
how many people would you expect to choose pepperoni
out of 350 people?
Let x = people who chose pepperoni
Number of people : people who chose pepperoni = 350 : x
Equate both ratios
25 : 18 = 350 : x
25/18 = 350/x
Cross product
25*x = 18*350
25x = 6,300
x = 6,300/25
x = 252
x = people who chose pepperoni = 252

.Find the point of intersection of the pair of lines. x + 5y = 8, -x + 2y = -1
Answer:
the point of interception is where the graphs meets
in this case we will solve using substition method
x + 5y = 8 .... 1
-x + 2y = -1 .....2
solve for the equation
x = 8 - 5y ...... 3
solve the equation in equation 2
-x + 2y = -1
-(8-5y ) + 2y = -1
-8 +5y + 2y = -1
7y = -1 + 8
7y = 7
divided by 7 on both sides
y = 1
solve the value of y in equation 3
x = 8 - 5y
x = 8 - 5(1)
x = 8 -5
x = 3
the point of interception (3 ; 1)

Answer:
20x-3y
Step-by-step explanation:
combine the like terms
so first do 10x-2x=8x
then you're gonna add from the line the 10x and the 2x which is going to give you 20x
no finally you are left with one number with the y variable, that is 3y.
Therefore your answer is 20x-3y

A researcher spoke to 20 people running a marathon in which 1,400 people participated. Of those 20 people, 5 competed only in professional sporting events, 12 competed in only amateur sporting events, and the rest competed in both. What was the population size for this study?
A. 5
B. 12
C. 20
D. 1,400
Answer:
Step-by-step explanation:
The population size is everybody running the race. It does not include people watching the race and it is not confined to just the 20 people the researcher talked to.
If it doesn't limit itself to the 20 people, then the 5 and 12 and 3 people are also too limiting.
