What is the surface area of the right cone below?
15
A. 496r units2
B. 184r units2
O C. 304units
D. 248r units2
Answers
Answer:
Option B
Step-by-step explanation:
Surface area of a cone is given by the expression,
V = πr(r + l)
Here, r = Radius of the circular base
l = Lateral height of the cone
By substituting the given values in the given expression of volume,
V = π(8)(8 + 15)
= 184π units²
Therefore, surface area of the given circular cone is 184π units².
Option B is the correct option.
Answer: 184

A. 10.4
Step-by-step explanation:
Supplementary means to add to 180. Take 128 from 180 (180-128) and you get 52. 52/5= 10.4. To check this work you can solve it with the value plugged into the equation. 128 + 10.4(5) = 180, therefore 10.4 is the correct answer.

Write an inequality for the graph.
Answers
Answer:
h(x) ≥ |x - 5| +1
Step-by-step explanation:
Given graph represents an absolute function (parent function)
f(x) = |x|
Since, graph of the function 'f' has been shifted 5 units to the right new function will be,
g(x) = f(x - 5)
g(x) = |x - 5|
Again function 'g' is shifted 1 unit upwards along the y-axis then the new function will be,
h(x) = g(x) + 1
h(x) = |x - 5| + 1
There is a shaded region representing the solution area lying above the intersecting dark lines,
Therefore, solution region will be re[presented by the inequality,
h(x) ≥ |x - 5| + 1

The class average on a math test was 80.3 and the standard deviation was 5.7.
What percentage of the class scored above a 86?
Answers
Answer:
= 15.866%
Step-by-step explanation:
The class average on a math test was 80.3 and the standard deviation was 5.7.
What percentage of the class scored above a 86?
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score = 86
μ is the population mean = 80.3
σ is the population standard deviation = 5.7
Hence:
z = 86 - 80.3/5.7
z = 1
Probability value from Z-Table:
P(x<86) = 0.84134
P(x>86) = 1 - P(x<86) = 0.15866
Converting to Percentage
= 0.15866 × 100
= 15.866%
Therefore, the percentage of the class scored above a 86 is 15.866%

Answers
Answer: 31.2 pies
Step-by-step explanation:
Kim sold pies for $5.00 each and earned $156 from doing so.
The number of pies she sold to get to this was x pies.
The formula for doing so is therefore:
5 * x pies = 156
5x = 156
x = 156 / 5
= 31.2 pies

What is the height of the cone below?
Answers
The height of the cone is h = 27
Formula:-
Step 1:-
The volume of the cone is V=\frac{1}{3} (base)(height)V=31(base)(height)
Given volume is V= 45 in^ 3
Given base of the cone is B= 5 in^2
Step 2:-
by using formula, we get solution
45 = \frac{1}{3} (5)(h)45=31(5)(h)
cross multiplication, we get
\frac{45 x 3}{5} =h545x3=h
now simplification, the height of the cone is h = 27
sauce: brainly
Answer:
27 in.
Step-by-step explanation:
Firstly, let's look at what we do know. We need to find the height of a cone and we know the area of the base (B) and we know the volume of the cone.
The first step is to determine the radius of the base, which we can use later.
The area of a circle is A = π r^2, so when we plug in the given information
5 = π r^2
And now we can solve for the radius
5/π = r^2
√(5/π) = r
r = 1.26
Now that we have the radius of the base, we can find the height of the cone using the volume formula.
V = π r^2 (h/3)
45 = π (1.26)^2 (h/3)
45 = π (1.59) (h/3)
45/(1.59π) = h/3
9.01 = h/3
3(9.01) = h
h = 27 in
gavin walks at a rate of 3 miles per hour.at this rate how far will walk in 4hours
Answers
Answer:
12 miles
Step-by-step explanation:
3 times 4 = 12
Answer: 12 miles
Step-by-step explanation:
This is right because if Gavin walks at a rate of 3 miles each hour and now there are 4 hours then that means we have to multiply 3 times 4. If we do that we get 12, and just to make sure to check it's 12 you can divide 12 by 4 (that equals 3) or 12 divided by 3 (and that equals 4.)

Answers
Answer:
it would be In 17 hours
Step-by-step explanation:
let me know if I am wrong or right thxs
Answer:
4 4/17 hours
Step-by-step explanation:
In one hour Jacob can paint 1/9 of the fence
In one hour Molly can paint 1/8 of the fence
This equation can determine how long it would take if they worked together:
1/9x + 1/8x = 1
multiply each term by lcm of 72 to eliminate denominators to get:
8x + 9x = 72
17x = 72
x = 72/17
x = 4 4/17 hours
Sarah has 4 pieces of yarn that are 6 yards each. She uses 9 pieces of yarn that are each 2 feet long. How much yarn does Sarah have left?
Answers
Answer:
54 feet of yarn
Step-by-step explanation:
We have a conversion rate of
1 yard = 3 feet
Sarah has 4 pieces of yarn that are 6 yards each.
Hence,
1 yard = 3 feet
6 yards = x
Cross Multiply
x = 6 × 3 feet
x = 18 feet
Therefore, 4 pieces of yarn are 18 feet each
Hence, total feet of yarn above = 4 × 18 feet = 72 feet
She uses 9 pieces of yarn that are each 2 feet long.
Total feet of yarn here is:
9 × 2 feet = 18 feet of yarn
Therefore, the amount of yarn Sarah have left is calculated as:
72 feet - 18 feet
= 54 feet of yarn
