3. Cindy's ice cream looks pretty normal. It is shaped like a cone topped with a half-sphere. The cone
has a height of 11 in and a radius of 6 in.
What is the approximate volume of the whole shape? Round your answer to the nearest tenth. Use
3.14 to approximate pi. (Show your work.)
Answer:
Answer: 284.7
Step-by-step explanation:
Step-by-step explanation:
radius of cone and hemisphere are the same
volume of half sphere=(1/2)*(4/3)*
=(1/2)*(4/3)*3.14* (4*4*4=64)
=133.97333
=133.97
volume of cone= (1/3)h
=(1/3)*3.14**9 (4*4=16)
=150.72
total volume=133.97+150.72
=284.69
=284.7
The point (17,−9) is translated to the point (6,2). Select the description of the translation.
A
9 down, 7 right.
B
11 left, 11 up
C
9 right, 11 up
D
11 left, 9 down plzzz answer..
Answer:
11 up , 11 left
Step-by-step explanation:
Given
[tex](17, -9)[/tex] to [tex](6,2)[/tex]
Required
Determine the translation rule
Considering the x coordinates.
From 17 to 6
6 is to the left of 17.
Using the translation rule:
[tex]x = x' + b[/tex]
[tex]17 = 6 + b[/tex]
[tex]17 - 6 = b[/tex]
[tex]11 = b[/tex]
[tex]b = 11[/tex]
Hence: From 17 to 6 is 11 units left translation
Considering the y coordinates.
From -9 to 2
2 is at the top -9.
Using the translation rule:
[tex]y = y' + b[/tex]
[tex]-9 = 2 + b[/tex]
[tex]-9 - 2 = b[/tex]
[tex]-11= b[/tex]
[tex]b = -11[/tex]
The negative value impies a upward translation.
Hence: From -9 to 2 is 11 units up translation
Rewrite the expression in the form 6^n 6^-6/6^-5
Answer:
6^-1
Step-by-step explanation:
6^-6 - (-5) = 6^(-6 + 5) = 6^(-1)
A lot of things are going on in this question. Notice how the 5 is handled. It starts off in the denominator as - 5 and when brought to the numerator it becomes -(-5) which makes it + 5.
The answer is then easy. It is 6^(-6 + 5) = 6^-1
You could give the answer as 1/6 but that is not what the question says.
Rebecca saved AED 175.30 in June and AED 132.50 in July. Then she bought a bicycle for AED 195.80. How much of her savings from June and July was left?
Answer:
her saving that was left from June and July is 112
Step-by-step explanation:
The computation of the saving amount left is shown below;
= Total saving in 2 months - amount spent
= 175.30 + 132.50 - 195.80
= 112
Hence, her saving that was left from June and July is 112
A farmer wants to build two fenced-off sections within his field, one in the shape of a rectangle and the other in the shape of a square. The side of the square must be equal to the width of the rectangle, x feet. The length of the rectangle must be 50 feet longer than its width. The field the farmer wants to build the two fenced sections in has an area of y square feet. The difference of the area of this field and the area of the fenced, square section needs to be at least 1,000 square feet. In addition, the sum of the fenced areas must be less than the area of the field. This is the system of inequalities that represents this situation. Which points represent viable solutions?

A bowl contains blueberries and strawberries. There are a total of 48 berries in the bowl. The ratio of blueberries to strawberries is 9 to 3. How many of each berry are in the bowl?
A bowl contains blueberries and strawberries. There are a total of 20 berries in the bowl. The ratio of blueberries to strawberries is 4 : 1. How many of each berry are in the bowl?
Answer:
a. 36 blueberries and 12 strawberries
b. 16 blueberries and 4 strawberries
Step-by-step explanation:
The computation of each berry in the bowl is shown below;
a. Total 48 berries
The Ratio of blueberries to strawberries is 9:3
So, the blueberries is = 48 × 9 ÷ (9 + 3) = 36
And, the strawberries is = 48 × 3 ÷ (9 + 3) = 12
b. Total 20 berries
The Ratio of blueberries to strawberries is 4:1
So, the blueberries is = 20 × 4 ÷ (4 + 1) = 16
And, the strawberries is = 20 × 1 ÷ (4 + 1) = 4

Amir has 48 ounces of cashews, walnuts, and pecans. He adds x ounces of peanuts to create a mixture. Write a function
M(x) that represents the number of ounces of all nuts in the mixture. Write a function N(x) that represents the number
of ounces of peanuts in the mixture. Then find (?) (x) and explain what this function represents.
Answer:
I don't know sorry
Step-by-step explanation:
ask tutor
The function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Given that, Amir has 48 ounces of cashews, walnuts, and pecans.
He adds x ounces of peanuts to create a mixture.
M(x) that represents the number of ounces of all nuts in the mixture.
M(x)=48
N(x) that represents the number of ounces of peanuts in the mixture.
So, N(x)=x
Now, (M/N)(x) = M(x)/N(x)
= 48/x
Therefore, the function N(x) that represents the number of ounces of peanuts in the mixture is N(x)=x.

A marine biologist earns $21.75 per hour. If she works 40 hours a week for 52 weeks a year, how much could she earn after 15 years?
Answer:
Step-by-step explanation:
EARNINGS FOR YEARS = PAY RATE/HOUR * HOURS/WEEKS * WEEKS/YEAR * YEARS
