Hope This Helps!Find the surface area and volume of the figure.
(Round to the nearest teeth as needed)
Answer:
Volume;
Let's find the volume of the hemisphere above,
Formula for hemisphere volume:
V = 2/3πr
Where pi(π) is 22/7 or 3.14, and 'r' is the radius.
(extra info:) D/2 = radius
So, diameter in this case is 6,
6/2 = 3 is the radius.
Replace values:-
V = 2/3πr
V = 2/3 x 3.14(3)
V = 2/3 x 9.42
V = 18.84/3
V = 6.28 feet is the volume for the hemisphere.
Now the cylinder's volume,
Cylinder volume formula:
V = π[tex]r^{2}[/tex]h
Where pi(π) is 22/7 or 3.14, 'r' is the radius which is being squared, and 'h' is the height.
Replace values (we figured out radius is 3);
V = π[tex]r^{2}[/tex]h
V = 3.14(3^2) x 10
V = 3.14(9) x 10
V = 28.26 x 10
V = 282.6 feet is the volume of the cylinder.
Add our volumes:-
6.28 + 282.6
= 288.88 feet is our volume.
Surface area;
Now the surface area formula of the cylinder is:
SA = 2πrh(lateral area) + 2π[tex]r^{2}[/tex](area of circle)
Replace values:
SA = 2πrh + 2π[tex]r^{2}[/tex]
SA = 2(3.14) x 10 + 2(3.14) x 3^2
SA = 6.28 x 10 + 6.28 x 9
SA = 62.8 + 56.52
SA = 119.32 is the surface area of the cylinder.
Now the surface area formula of the hemisphere;
SA = 3πr²
Replace values;
SA = 3πr²
SA = 3(3.14) x 3^2
SA = 9.42 x 9
SA = 84.78 is the surface area of the hemisphere.
Add the areas;
119.32 + 84.78
= 204.1 feet is the surface area.
Which values from the set {0, 12, 2.5, 4} make the inequality 8g < 4 true?
a.0
b.1/2
c.2.5
d.4
Answer:
a. 0
Step-by-step explanation:
Which values from the set {0, 12, 2.5, 4} make the inequality 8g < 4 true?
Our inequality:
8g < 4
Substitute each values from the set {0, 12, 2.5, 4} for g, to find which value makes the inequality true.
For 0:
8g < 4
8(0) < 4
0 < 4
This statemen is true, because 0 is less than 4
For 12:
8g < 4
8(12) < 4
96 < 4
This statemen is false, because 96 is NOT less than 4
For 2.5:
8g < 4
8(2.5) < 4
20 < 4
This statemen is false, because 20 is NOT less than 4
For 4:
8g < 4
8(4) < 4
32 < 4
This statemen is false, because 32 is NOT less than 4
Hope this helps!

36000π cubic feet
Answer:
is in the shape of a sphere
diameter = 60 feet
radius = r = 60/2 = 30 feet
Step-by-step explanation:
volume of sphere = 4/3 × π × r³
= 4/3 × π × 30³
=4/3π × 27,000
= 36000π cubic feet
Answer:
36000π cubic feet
Step-by-step explanation:
Given :
Diameter of sphere = 60 feetSolving :
Volume = 4/3πr³But 2r = d or r = d/2Therefore, volume is :⇒ 4/3π(d/2)³⇒ 4/24πd³⇒ 1/6πd³⇒ 1/6 x 60 x 60 x 60 x π⇒ 10 x 3600π⇒ 36000π cubic feetFind the missing dimension. Use the scale 1 : 15.

Which of the following best explains why one graph appears skewed and one graph appears symmetrical? The scale of the box-and-whisker plot does not start at zero. The interval of the box-and-whisker plot is too large. The interval of the stem-and-leaf plot is not consistent. The scale of the stem-and-leaf plot is too small for the set of data.
The statement that best explains why one graph appears skewed and one graph appears symmetrical is given by: Option C: The interval of the stem-and-leaf plot is not consistent.
What is a symmetric distribution?A symmetric distribution oftenly refers to the distribution which looks symmetric about a fixed line.
For this case, the missing image is attached below.
The stem leaf plot represents the considered bar plot.
But stem leaf plot seems symmetric whereas the box plot isn't.
This is because the stem and leaf plot is missing '5' in its stem, making the interval inconsistent.
Doing inconsistant graphing isn't allowed as that represents distorted data, as for this case, the data seems symmetric when it isn't.
Thus, the statement that best explains why one graph appears skewed and one graph appears symmetrical is given by: Option C: The interval of the stem-and-leaf plot is not consistent.

Tom drove to visit a museum in Chicago. He traveled at a constant rate of 50 miles per hour for 2 hours. Then he traveled at a constant rate of 65 miles per hour for 1 hour. What is the total distance Tom traveled to the museum?
O:75
O:90
O:165
O:255
Answer:
165
Step-by-step explanation:
First, we multiply 50 and 2 to find out how much they traveled first, which is 100. And then, multiply 65 and 1 to get 65 for the second part. Add then, to get 165. Hope this helps!
Answer:
The answer is 165 miles.
This is how I solved it:
First I made a chart like the one in the picture
Then I inserted the Rate for each part of the trip. The rate for Part One is 50 miles per hour, and the rate for Part Two is 65 miles per hour.
Next, I would insert the Time for each part of the trip. The time for Part One is 2 hours, and the time for Part Two is 1 hour.
Because we now have the values for r and t for each part of the trip, we need to calculate the distance for each part by using the distance formula, d=r x t, and multiplying the rate and the time.
For Part One, multiply 50 miles per hour x 2 hours; this equals 100 miles. For Part Two, multiply 65 miles per hour times 1 hour; this equals 65 miles.
So, Tom traveled 165 miles to the museum.
Hope this isn't confusing XD

A local candy shop sells boxes of chocolate for $3.75 each. If a customer purchases six or more boxes, the cost is only $3.25 per box, plus the customer has an additional $5 fee per order. If C(x) represents the total cost and x represents the number of boxes, which of the following functions best models this scenario?
The piecewise function that models the scenario is:
c(x) = $3.75*x + $5 if x < 6
c(x) = $3.25*x + $5 if x ≥ 6.
How to write a piecewise function?
A piecewise function is a function that behaves differently in different intervals of the domain, like this one, where the cost per box changes depending on the number of box.
The function in this case, if we define x as the number of boxes bought, is:
c(x) = $3.75*x + $5 if x < 6c(x) = $3.25*x + $5 if x ≥ 6.Where the cost per box changes for x equal or larger than 6.

A triangle, ABC, has coordinates A (-2, 0), B (-2, 5) and C (-4, 0). What is the length of the shortest side?
Answer: 2 units.
Step-by-step explanation: When you graph the points given, it gives you this shape in the image below. The hypotenuse (longest side of triangle) is found by doing the following:
a^2 + b^2 = c^2, where a and b are the legs (the other sides of the triangle) and c is the hypotenuse.
5^2 + 2^2 = 29.
√ 29 ≈ 5.38, and that is the length of the hypotenuse.
The shortest side is the bottom side, which is 2 units. Therefore, that is your answer.

How do I find the area of the shaded and none shaded regions?
Answer:
96 for both
Step-by-step explanation:
You can see that each region is equal because it is half. 8*12=96. (96/2)*2= Shaded region. 96
So that means the unshaded region is also 96.
Answer:
Find the area of the whole shape, then find the area of the shaded area (which is 2 triangles *).
after that, just minus the area of the shaded areas from the area of the whole shape...
Total Area = Lenght x Width... (16 x 12)
Area of triangle 1 = 1/2 x Base x Height.... (1/2 x 12 x 8)
Area of triangle 2 = 1/2 x Base x Height.... (1/2 x 12 x 8)
Area of Shaded Region = A of T1 + A of T2
Area of Non-Shaded Region = Total Area - Area of of Shaded Areas

Work out the value of x
2x
7x
this is a Co-intirior angle
Step-by-step explanation:
The sum of co-interior angle = 180°
Now,
2x + 7x = 180°
9x = 180°
x = 180° ÷ 9
x = 20°
Answer:
x = 20
Step-by-step explanation:
Co-interior angles (also called same-side interior angles) are two angles that are on the same side of the transversal and on the interior of (between) the two parallel lines.
Same-side interior angles theorem: If two parallel lines are cut by a transversal, then the same side interior angles are supplementary (add up to 180º).
Therefore, if 2x and 7x are co-interior:
⇒ 2x + 7x = 180
⇒ 9x = 180
⇒ x = 20

Step-by-step explanation:
In the morning, this worker was in for a total of 4 hours. Since the wage is $11/hr, we have to multiply 4 by 11.
11 * 4 = 44
In the afternoon, they worked for 4 hours and 45 minutes. Now, we have to multiply 4 3/4 (which is the fraction form of 4 hours and 45 mins) by 11.
11 * 4 3/4 = 52.25
Now, to find the total pay, we add together both the morning and afternoon pays.
44 + 52.25 = 96.25
Therefore, the total pay is $96.25
