Step-by-step explanation:
The formula for the volume of a cone is [tex]V =\frac{1}{3} \pi r^{2} h[/tex], where r is the radius of the base and h is the height.
In this figure, the cone's radius is 4 and the cone's height is 8.
Substituting in the values, we get:
[tex]V =\frac{1}{3} \pi (4)^{2} (8)[/tex]
Using 7 instead of 8 here would be a mistake, as 7 refers to the height of the cylinder below it.

If the measure of \angle∠4 is 68 degrees,, find the measure of \angle2∠2 in degrees.
Answers
Hi, there! I'd love to help you out!
We know complementary angles add up to 90 degrees.
Let's say our first angle is x:
x = first angle
It tells us the other angle is 68 degrees more. So we are just adding 68 to our other angle:
x = first angle
x + 68 = second angle
Now add the two and set it equal to 90 degrees:
x + x + 68 = 90
2x + 68 = 90
-68 -68
2x = 22
/2 /2
x = 11 first angle
x + 68 = 11 +68 = 79 degrees second angle

Identify the x- and y-intercept and graph the equation on the coordinate plane to the left. What is the x-value when y is 3? Answer these questions in the text box below.
Answers
Answer:
x-int is 24/5 y-int is 8 and x value when y is 3 is 3
Step-by-step explanation:
So for the x int, we can plug in 0 for y, because in a x intercept, the y is zero.
5x=24
x=24/5
for the y int, we can plug in 0 for x, because in a y intercept, the x is zero.
3y=24
y=3
now when y is 3, we can just plug that in.
5x + 3 times 3 = 24
5x+9=24
5x=15
x=3

Find the volume...!!!
Answers
Answer:
volume = 143.1 m^3
Step-by-step explanation:
here's your solution
=> volume of cuboid = area of base * height
=> volume = 53*2.7
=> volume = 143.1 m^3
hope it helps
Answer is below. Look at the explanation to understand my answer.
To find the volume, you simply multiply all the lengths up to get your answer.
The formula is for finding the volume of a rectangular prism is: L × W × H. Normally there is 3 lengths, but there is only 2. We can still solve by using the same formula, instead of L × W × H, the formula will be Base Area × Height or BA × H.
Here is a breakdown: Solving for a Cuboid (rectangular prism) is easy; all you need to do is multiply all the units.
With that being said...
53 times 2.7 is 143.1 m²
Therefore, 143.1 is the volume
Let me know of questions or concerns about my answer.
Formulas:
V = L × W × H (Length × Width × Height)
V = BA × H (Base Area × Height)

A basketball game a team made 52 successful shots they were a combination of 1- and 2- point shots the team scored 86 points in all write and solve a system of equations to find the number of each type of shot
Answers
Answer: 15
Step-by-step explanation:
x = one point shots
y = two point shots
1) Setup your equations.
x + y = 52
x + 2y = 89
2) Isolate a variable.
x = 52-y
3) Plug in.
(52-y) + 2y = 89
52 +y =89
y=37
4) Solve for x.
x = 52 -37
x=15
5) Check your answer.
15 + 2(37) = 89
15+74=89
89=89
37+15 = 52
52=52
x = one point shots
y = two point shots
1) Setup your equations.
x + y = 52
x + 2y = 89
2) Isolate a variable.
x = 52-y
3) Plug in.
(52-y) + 2y = 89
52 +y =89
y=37
4) Solve for x.
x = 52 -37
x=15
5) Check your answer.
15 + 2(37) = 89
15+74=89
89=89
37+15 = 52
52=52

The owner of a small restaurant bought 75 kilograms of rice. Each week, the restaurant uses 4.5 kilograms of rice.
Function `r` gives the remaining amount of rice, in kilograms, as a function of the number of weeks since the restaurant owner bought the rice.
Solve the equation `r(w)=30`and explain what the solution means in this situation.
Answers
Answer:
r(t) = 75 kg - (4.5 kg/wk)w
Step-by-step explanation:
Let r(t) represent the amount of rice remaining after w weeks.
Then:
r(t) = 75 kg - (4.5 kg/wk)w
please mark as brainliest
Answer:
w=10 and this means that 10 weeks after the rice was bought, 30 kilograms of rice remain.
Step-by-step explanation:
r(w)=75-4.5w is an equation for this function so I'll be using this. First insert r(w)= 30 into the equation.
75-4.5w=30
75-75-4.5w=30-75
-4.5w=-45
-4.5w/-4.5 = -45/ -4.5
w=10
Apologies if the explanation isn't thorough, I'll glady provide more details if necessary.

Since it takes Angel 2 minutes to run 1 lap, she will take
2.5 laps1 km⋅2 minutes1 lap=5 minutes1 km.
So it takes Angel 5 minutes to run 1 km.
Since it takes Jayden 5 minutes to runs 3 laps, she runs 1 lap in 53 minutes. Thus, it takes Jayden
2.5 laps1 km⋅5 minutes3 laps=52⋅53 minutes/km=256 minutes/km=416 minutes/km.
