the composite figure?
pi(5^2)(13)-1/3pi(5^2)(12) pi(5^2)(13)-1/3pi(5^2)(25)
pi(5^2)(13)+1/3pi(5^2)(12)
pi(5^2)(13+1/3pi(5^2)(25)
Answer:
C.
[tex]V = \pi * 5^2(13) +\frac{1}{3}\pi * 5^2 (12)[/tex]
Step-by-step explanation:
Given:
The figure is a combination of a cone and a cylinder
Radius (of both), [tex]r = 5[/tex]
Height of Cylinder, [tex]H_1 = 13[/tex]
Height of Cone, [tex]H_2 = 25 - 13 = 12[/tex]
Required:
Volume of the figure
Let V represents the volume of the figure;
[tex]V_1[/tex] represents the volume of the cylinder
[tex]V_2[/tex] represents the volume of the cone
So, [tex]V = V_1 + V_2[/tex]
Where [tex]V_1 = \pi r^2H_1[/tex] and [tex]V_2 = \frac{1}{3}\pi r^2 H_2[/tex]
So, V becomes
[tex]V = \pi r^2H_1 + \frac{1}{3}\pi r^2 H_2[/tex]
Factorize the above expression
[tex]V = \pi r^2(H_1 + \frac{1}{3}H_2)[/tex]
Substitute [tex]r = 5[/tex]; [tex]H_1 = 13[/tex];[tex]H_2 = 12[/tex]
[tex]V = \pi * 5^2(13 + \frac{1}{3} * 12)[/tex]
[tex]V = \pi * 5^2(13 + \frac{1}{3} * 12)[/tex]
Open Bracket
[tex]V = \pi * 5^2(13) +\pi * 5^2 \frac{1}{3} (12)[/tex]
Reorder
[tex]V = \pi * 5^2(13) +\frac{1}{3}\pi * 5^2 (12)[/tex]

Charlie and Leo were playing with toy cars. Charlie said to Leo that if you give me one car, then i will have twice as many cars as you have. Leo said if charlie gives him a car, they will be equal. How many cars does each boy have?
Answer:
Charlie has 6 and Leo has 4
Step-by-step explanation:
6-1=5 and 4+1= 5
brainliest plsss
Answer:
In the beginning, Leo had 3 cars and Charlie had 3 cars.
In this problem, the statements seem to never be true if applied in the initial value. But if we take the value from the first statement and take it in the second, Leo and Charlie having 3 cars is true.
Step-by-step explanation:
Charlie said to Leo that if you give me one car, then i will have twice as many cars as you have.
[tex](L_{1} - 1) = 2L_{2} = C_{2}[/tex]
From that statement after Leo gives Charlie a car, we'll have something like:
Charlie's Leo's
2 1
4 2
6 3
Also, from that statement we can imply that we're not dealing with a great amount of cars, because the next statement won't be true.
Leo said if Charlie gives him a car, they will be equal.
[tex]L_{1}= C_{1} - 1[/tex]
Another thing is that if the second consideration holds true after the first statement. I will considerate that.
So,
In the beginning, Leo had 3 cars and Charlie had 3 cars.
In this problem, the statements seem to never be true if applied in the initial value.
50% increase followed by a 33 1/3% decrease
Answer:
A 50% increase followed by a 33/1/3% decrease. = ? (1 + 0.5)*(1 - 0.3333333) = 1.5 * 0.666667 = 1. Result is same as original.
A 50% increase followed by a 33 1/3% decrease is a net decrease of 16 2/3%.
Here is the explanation:
A 50% increase means that the value is multiplied by 1.5.
A 33 1/3% decrease means that the value is multiplied by 0.6666666666666666.
So, the net effect of the two changes is:
(1.5 × 0.6666666666666666) = 1 - (1/6) = 0.8333333333333334
This is a decrease of 16 2/3%.
For example, if you start with a value of 100, then a 50% increase followed by a 33 1/3% decrease will result in a final value of 83.33.

Find the exact value of each trigonometric function for the given angle θ.
Answer:
[rad] 2.41
Step-by-step explanation:
Since it gave you the point and the angle to find, you simply just have to solve for the inverse of cot. Remember cot is the opposite of tan, so cot is cos/sin. In that case, we plug into the calc (in radians):
cot^-1(-√5/2)
And we should get 2.41 as our answer!
Stephen and Bridget win some money and share it in the ratio 4:1. Stephen gets £27 more
than Bridget. How much did Bridget get?
Answer:
15 euros
Step-by-step explanation:Add the both ratio together then take the of stephen divided by the sum of the ratio then collect like terms them subtract the answer from stephen's share.
I hope this helps.
Answer: Bridget will get $9
Step-by-step explanation:
Let the ratio of sharing between Stephen and Bridget be 4x and x
respectively .
According to the question ,
Stephen gets $27 more than Bridget.
Then ,
4x - x = 27
→ 3x = 27
→ x = 9
Amount of money that Bridget gets = $ 9
When solving the equation 3x + 9 = 17x - 11, the first step is to?
Step-by-step explanation:
The first step is to move the like terms to same side of equation
3x + 9 = 17x - 11 ➡ 9 + 11 = 17x - 3x
then we add like terms
20 = 14x simplify if needed
10 = 7x and x = 10/7

Step-by-step explanation:
It takes 160 ribbons to make 4 football mums. What is the constant of proportionality that relates the number of football mums made, y, to the number of ribbons used, x? 40 140 80 14
Answer:
40
Step-by-step explanation:
If two variable y and x are related to one other
then they can be represented as y = kx.
where k is constant of proportionality
Number of football mums is represented by y
and number of ribbons is represented by x
Then y = kx
Also, It takes 160 ribbons to make 4 football mums
substituting y with 4 and
substituting x with 160 in y = kx, we have
4 = k*160
=> k = 4/160 = 1/40
Thus, constant of proportionality is 1/40.
But here option given are 40 140 80 14
so ,equation can be represented as
x = ky
substituting y with 4 and
substituting x with 160 in x = ky , we have
160 = k*4
=> k = 160/4 = 40
Thus, for equation x = ky , constant of proportionality is 40.

What are the solutions to the quadratic equation x2 – 16 = 0?
O x = 2 and x = -2
x = 4 and x = -4
x = 8 and x = -8
x = 16 and x = -16
Answer: x=8 and x=-8
Step-by-step explanation:
To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.
x²-16=0
(x+8)(x-8)=0
x+8=0
x=-8
x-8=0
x=8
Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.

Two bottles of water and three small bags of fruit cost a total of £2.55. If a bottle of water costs 15p more than a bag of fruit, what is the cost of a bag of fruit?
Answer:
45p
Step-by-step explanation:
2w+3f=2.55
w=f+15p
2w=2f+30p
2f+3f+30p=2.55L
5f+30p=255p
5f=255-30
5f=225p
f=225/5=45p
