Answer:
2787.6 (rounded to nearest tenth)
Step-by-step explanation:
The formula for the volume of a hemisphere is [tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] × r³ where r is the radius of the hemisphere. You can apply the formula to answer the question.
Volume = [tex]\frac{2}{3}[/tex] × [tex]\pi[/tex] × 11³
= 887[tex]\frac{1}{3}[/tex][tex]\pi[/tex]
= 2787.6 (rounded to nearest tenth)
Answer:
2878.6!!!!!
Step-by-step explanation:
the volume with the radius of 11 inches so it would be 2878.6n
Barbara wants to buy some glittery heart-shaped beads to make friendship bracelets. The beads she wants come in a small pack with 90 beads or a large pack with 300 beads. The small pack costs $3.60, while the large pack costs $9.00. Which pack is the better value? small pack ll large pack
Answer:
The large pack is a better deal!
Step-by-step explanation:
so first we need to figure out how much the individual beads cost.
Small pack: $ 3.60÷90 = 0.04 cents per bead
Large pack: $9.00 ÷ 300 = 0.03 cents per bead
Hope this helps!!
Have a great day!!

The difference between the roots of the quadratic equation x^2-14x+q=0 is 6. Find q.
Answer:
The value of q is 40
Step-by-step explanation:
In the quadratic equation ax² - bx + c = 0, where
a = 1
b is the sum of its two roots
c is the product of its two roots
Assume that the roots of the quadratic equations are x and y
∵ The quadratic equation is x² - 14x + q = 0
∴ a = 1 , b = 14 and c = q
∵ b is the sum of its two roots
∵ Its roots are x and y
∴ x + y = 14 ⇒ (1)
∵ The difference between the roots is 6
∴ x - y = 6 ⇒ (2)
Now we have a system of equation to solve it
Add equations (1) and (2)
∴ 2x = 20
- Divide both sides by 2
∴ x = 10
Substitute the value of x in equation (1) or (2) to find y
∵ 10 + y = 14
- Subtract 10 from both sides
∴ y = 4
∵ c is the product of the two roots
∴ c = 10 × 4 = 40
∵ c = q
∴ q = 40
The value of q is 40

Monthly grocery cost based on the average number of shopping trips is predicted using the least-square regression line, ŷ = 275.3 + 90.7x, where ŷ represents the predicted monthly expense and x represents the average number of trips. A shopper visits the grocery store an average of 3.2 times and has a monthly cost of $520. What is the residual for the shopper?
45.54
76.47
−45.54
−76.47
90.7
Answer:
−45.54
Step-by-step explanation:
Just took the test
The residual for the shopper will be equal to -45.54. Hence, option C is correct.
What is an equation?Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.
This relationship is illustrated by the left and right expressions being equal. The left-hand side equals the right-hand side is a basic, straightforward equation.
As per the given data provided in the question,
The given equation is,
y = 275.3 + 90.7 x
Here, x is the number of trips and y is the total monthly expense.
Then,
Shopper monthly cost = $520
Number of visits by the shopper in a month = 3.2
So, the residual for the shopper will be,
$520 = 275.3 + 90.7 (3.2)
$520 = 275.3 + 290.24
= -45.54

Johan can drive 270 miles on 9 gallons of gas. What is his average mileage?
Hey there!
The correct answer is 30 miles per gallon.
If he can drive 270 miles on 9 gallons, we want to find the unit rate, or miles per gallon. We can do this by dividing 270 by 9. To make it easier, we will take off the zero, and do 27/9, which is 3. Now we add the 0 back on, which gives us 30. Therefore, his average mileage is 30 miles per gallon.
Have a terrificly amazing day! :D
Answer:
30 miles per gallon
Step-by-step explanation:
1. 30 miles per gallon since 360/12 = 30
2. 270 / 9 = 30
During a football game, the ball is placed 20 yards 2 feet from the goal line. How many feet from the goal line is the football?
Answer:
62 feet
Step-by-step explanation:
During a football game, the ball is placed 20 yards 2 feet from the goal line. How many feet from the goal line is the football?
Step 1
We convert 20 yards to feet
1 yard = 3 feet
20 yards = x feet
Cross Multiply
1 yard × x feet = 20 yards × 3 feet
x feet = 20 yards × 3 feet/1 yard
x feet = 60 feet
Step 2
How many feet from the goal line is the football?
This is calculated as:
20 yards 2 feet =
60 feet + 2 feet = 62 feet
Therefore, the football is 62 feet from the goal line
