Find the volume of the composite solid. Round your answer to the nearest tenth.
Answers
Answer:
646
Step-by-step explanation:
To solve this, you would need to know the volume of a sphere and volume of a cube.
Volume of a cube is L x W x H
8x8x8 which gives you 512
The volume of a sphere is [tex]\frac{4}{3} \pi (r)x^{3}[/tex]
(radius which is 8/2=4) 4/3 pi (4)^3=268.08
Because this is half a sphere, simply divide the volume by 2 and you should get 134.04.
512+134.04=646.04
=646 cm cubed

Answers
Answer:
y = -2/3x + 5 1/3
Step-by-step explanation:
Find the slope:
4 - 6 / 2 - (-1) = -2/3
Put it in point-slope form:
y - 6 = -2/3(x + 1)
rearrange:
y - 6 = -2/3x - 2/3
y = -2/3x + 5 1/3

Find the x- and y-intercepts of the graph of -x +y = 8. State your answers as
whole numbers or as improper fractions in simplest form.
Answers
Given:
The equation is
[tex]-x+y=8[/tex]
To find:
The x- and y-intercepts.
Solution:
We have,
[tex]-x+y=8[/tex]
Put x=0 in the given equation to find the y-intercept.
[tex]-(0)+y=8[/tex]
[tex]y=8[/tex]
Put y=0 in the given equation to find the x-intercept.
[tex]-x+(0)=8[/tex]
[tex]-x=8[/tex]
[tex]x=-8[/tex]
Therefore, the x-intercept is -8 and the y-intercept is 8.
area of a trapizium is 84m².its pararrell sides are 12m and 9m. find its hiegh
Answers
Answer:
8m
Step-by-step explanation:
We can convert the trapezium into a rectangle to make finding the area easier.
Say that the top side is 9m, and that the bottom side is 12m.
12 - 9 = 3
3/2* = 1.5
*Note that we are dividing by two to get the "overhang" of the bottom side.
Now that we have our overhang, we can find the length of the "t-rect"**.
**"T-rect" refers to a rectangle that has been formed by changing a trapezium into a rectangle.
12 - 1.5 = 10.5
9 + 1.5 = 10.5
The length of the t-rect is 10.5.
84/10.5 = 8
The height of the t-rect is 8m.
Since the height of the original trapezium is equal to the height of the t-rect***,
***Since we have only adjusted the length
this also means that 8m would also be the height of the original trapezium.
Now, there is a second way of doing this.
Find the median of 12 and 9.
9, 10, 11, 12
10, 11
The median is 10.5.
84/10.5 = 8
You get the same answer. These methods could be used as a solve-then-check method to another problem like these.
Hope this helps. Have a nice day.

Answer:
137 [tex]ft^2[/tex]
Step-by-step explanation:
1. Approach
Break up the given figure into smaller figures. One can break up this figure into a rectangle, and a triangle. After doing so, one can calculate the area of each of the smaller figures, and then add up the values.
2. Calculate the area of the triangle
If one were to cut the top figure off, one would get a triangle with a base of (3ft), and a height of (6ft). One can calculate the area of the figure using the formula;
[tex]\frac{base*height}{2}[/tex]
Substitute;
[tex]\frac{6*3}{2}\\\\= \frac{18}{2}\\\\\ 9[/tex]
3. Calculate the area of the rectangle;
Now, one is left with a rectangle with dimensions (16ft), and (8ft). To find the area of this figure, use the formula;
[tex]base * height[/tex]
Substitute;
[tex]16 * 8\\\\= 128[/tex]
4. Find the area of the whole figure
Now add the area of the triangle, and the area of the rectangle together.
(Rectangle) + (Triangle)
= 128 + 9
= 137

On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.
Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):
B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)
Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.
Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.
Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)
Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.
