what is the circumference
Answer: 69.43 cm
Step-by-step explanation:
Given: Arc length (JK) = 40.5 cm
Central angle ∠ JLK = 210°
Arc length = [tex]\dfrac{x}{360}\times\text{Circumference}[/tex]
[tex]\Rightarrow\ 40.5=\dfrac{210}{360}\times\text{Circumference}\\\\\Rightarrow \text{Circumference} =40.5\times\dfrac{360}{210}\\\\\approx69.43\ cm[/tex]
Hence, Circumference = 69.43 cm

look at the cups shown below (images are not drawn to scale). how many more cubic inches of juice will cup B hold than cup A when both are completely full? round your answer to the nearest tenth.
Answer:
18.8 cubic inches
Step-by-step explanation:
✔️Amount of juice Cup B will hold than Cup A = Volume of cup B - volume of cup A
✔️Volume of Cup B = Volume of cylinder = πr²h
radius (r) = ½ of 2 = 1 in.
height (h) = 7 in.
Volume of cup B = π*1²*7 = 21.99 in.³
✔️Volume of Cup A = Volume of cone = ⅓πr²h
radius (r) = ½ of 2 = 1 in.
height (h) = 3 in.
Volume of cup B = ⅓*π*1²*3 = 3.14 in.³
✔️Amount of juice Cup B will hold than Cup A = 21.99 in.³ - 3.14 in.³ = 18.8 in.³ (nearest tenth)

Rachel earns $67.50 for working 9 hours at the dairy farm. How much does Rachel make per hour? How much would Rachel make if she works 5 hours a day for 6 days?
Answer:
$225
Step-by-step explanation:
Frist, we need to figure out how much Rachel makes per hour. For 9 hours of work, she makes $67.50
67.5 / 9 = 7.5
Rachel makes $7.50 per hour
Now we can add up all the hours she worked.
5 hours a day for 6 days
5 x 6 = 30
She worked 30 hours at a rate of $7.50 per hour
7.5 x 30 = 225
She earned $225

Can someone explain this problem to me?? After a price reduction of x%, an item has its price increased to its original value. What was the percent of increase? Express your answer as a common fraction in terms of x.
Answer:
[tex]\frac{-100(100+x)}{(x-100)}[/tex]
Step-by-step explanation:
Let the original price of the item = p
Let there was q% of increase on the original value, so
the printed price of the item, [tex]C= p+p \frac{q}{100}=p(1+\frac{q}{100})[/tex]
After a price reduction of x%, the has its price increased to its original value, so,
[tex]C-C\times \frac {x}{100} =[/tex] original price + increased price
[tex]p(1+\frac{q}{100})-p(1+\frac{q}{100})\times \frac {x}{100} = p+p[/tex]
[tex](1+\frac{q}{100})-(1+\frac{q}{100})\times \frac{x}{100} =2[/tex]
[tex]-(1+\frac{q}{100})\times \frac{x}{100} =2-1-\frac{q}{100}[/tex]
[tex]-(1+\frac{q}{100})\times \frac{x}{100} =1-\frac{q}{100}[/tex]
[tex](1+\frac{q}{100})\times \frac{x}{100} =\frac{q}{100}-1[/tex]
[tex]\frac{x}{100}+\frac{q}{100}\times\frac{x}{100}-\frac{q}{100}=-1[/tex]
[tex]x+x \times \frac{q}{100}-q=-100[/tex]
[tex]q(\frac{x}{100}-1)=-100-x[/tex]
[tex]q=\frac{-100(100+x)}{(x-100)}[/tex]
Hence, the percent of the increase is [tex]\frac{-100(100+x)}{(x-100)}[/tex]
The roots of $y^2 + 5y - 11 = 0$ are $a$ and $b$. Find $(a + 3)(b + 3).$
Since a and b are roots of y² + 5y - 11, we have
y² + 5y - 11 = (y - a) (y - b)
and expanding the right side gives
y² + 5y - 11 = y² - (a + b) y + ab
so that
a + b = -5
ab = -11
Now,
(a + 3) (b + 3) = ab + 3 (a + b) + 9
(a + 3) (b + 3) = -11 + 3 (-5) + 9
(a + 3) (b + 3) = -17
Jerry is paid twice a month. Last month, his first paycheck was for $52. He paid $18 for gasoline and $20 for food. His next paycheck was for $65. He paid $16 for gasoline and $25 for food. What is his balance?
Answer:
Jerry's current balance is $41.
Step-by-step explanation:
We need to subtract what he spent, and add what he gained.
So:
(Money spent)
$18 + $20 = $38
(Current balance)
$52 - $30 = $22
(Current balance)
$65 + $22 = $87
$25 + $16 = $41
Current balance: $41

Your answer
Answer:
∠ 6 = 28°
Step-by-step explanation:
152° and ∠ 5 are corresponding angles and are congruent, then
∠ = 152°
∠ 5 and ∠ 6 are adjacent angles and are supplementary, thus
∠ 6 = 180° - 152° = 28°

Which equation represents this problem? The time it takes Tomás to bike to the community center is 2 minutes less than half the time it takes him to bike to the city park. It takes Tomás 18 minutes to bike to the community center. Let p = the time it takes Tomás to bike to the park.
A. 2p+12=18
B.12p+2=18
C.2p–12=18
D.12p–2=18
Answer:
The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18 ⇒ D
Step-by-step explanation:
Let us solve the question
∵ p is the time it takes Tomás to bike to the park
∵ The time it takes Tomás to bike to the community center is 2 minutes
less than half the time it takes him to bike to the city park
→ That means multiply p by [tex]\frac{1}{2}[/tex] , then subtract 2 from it
∴ The time to the community center = [tex]\frac{1}{2}[/tex] (p) - 2
∴ The time to the community center = [tex]\frac{1}{2}[/tex] p - 2
∵ It takes Tomás 18 minutes to bike to the community center
→ Equate The time to the community center by 18
∴ [tex]\frac{1}{2}[/tex] p - 2 = 18
∴ The equation that represents this problem is [tex]\frac{1}{2}[/tex] p - 2 = 18

Find the values of x and z
Answer:
z = 92 degrees
x = 6
Step-by-step explanation:
z and the angle that measures 92 degrees are vertical angles which means they are congruent. So, z = 92 degrees.
The total measure of all these angles is 360 degrees. Subtract 92*2 from 360 and divide the answer by 2. You get 88.
88 = 9x + 34
Solve for x.
x = 6
Answer:
z = 92°x = 6Step-by-step explanation:
For x:
Write and algebraic equation: 92 + (9x + 34) = 180Combine like terms: 126 + 9x = 180Subtract 126 from each side, so it now looks like this: 9x = 54Divide each side by 9 to cancel out the 9 next to x. It should now look like this: x = 6For z:
Because the 92° angle and z make a vertical angle, 92° = z°I hope this helps!
