Remi has two cone-shaped containers with the same diameter. He will place the smaller container inside the larger one. Before he does this, he wants to fill the larger container with water so that it will be completely full but won't spill when he places the smaller container inside. The diameter of both containers is 14 cm. The height of the smaller container is 3 cm, and the height of the larger container is 17 cm.What volume of water must Remi put in the large container? Round your answer to two decimal places and use 3.14 to approximate pi.

Answers

use the formula for the cone
1/3 times (area of base) times height

so first we want to find the volume of both cones then subtract the volume of the smaller container from the larger one

area of base for both are equal
area of base=area of circle=pi times r^2
radius=diameter/2
diameter=14
radius=14/2
radius=7

pi times 7^2
pi times 49
3.14 times 49=153.86

smaller so 1/3 times 153.86 times 3=smaller cone=153.86 cm^3

larger
so 1/3 times 153.86 times 17=871.873

subtract smaller from larger

871.873-153.86=718.013 cm^3
the volume of water needed is 718.01 cm^3

If x = 11 and y = 7, what is the value of the following expression?
x - 8 + 4y

Answers

I think it is 31 I might be wrong but I tried :)

If you change the x with the 11 and the y with 7, you subtract the 8 from 11, than add 4 times 7. And you get 31

Decimal 0.003 is 1/10 of

Answers

Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplied by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.

So 0.03 is your answer

To find 61 x 1000, annex zeros to form the product?

Answers

Answer:

The product is $61* 1000=61000$

Step-by-step explanation:

Given : Expression $61* 1000$

To find : Annex zeros to form the product?

Solution :

Expression $61* 1000$

When we multiply any number with multiple of 10, then we will first multiply number by 1 and then put the the number of zero in multiple of 10.

So, multiply 61 by 1 and then add 3 zeroes to the product.

$61* 1000=61000$

Therefore, The product is $61* 1000=61000$

All you do is times 61 by 1 and add three zeros, so the answer is 61000.

Hope that works.

Neil and Manny have different amounts of money. If Manny gives Neil $6, then Neil and Manny will have the same amount of money. If Neil gives Manny $6, then Manny will have 3 times as much money as Neil. Together, do Neil and Manny have enough money to buy a $50 video game? Show your work or explain how you found your answer. Define any variables you use.

Answers

Neil would have $6, and Manny would have $12. $6+$6=$12 that manny has, so they would both have the same amount of money. But if Neil gives manny $6, then Manny would have $18, which is three times greater than $6 that Neil has. $12+$6 only equals $18, so they don't have enough money to buy the game.

Given the functions below, what is f(x)−g(x) ?f(x)=7x3−10x2−5g(x)=2x3+7x2−9
A
5x3−17x2+4

B
5x3−3x2−14

C
9x3−3x2−14

D
5x3−17x2−14

Answers

Answer:

f(x)-g(x)=5x^3-17x^2+4 which appears as option A

Step-by-step explanation:

Simply subtract the function's expressions as shown below, and combine like terms to express the final result:

$f(x)=7x^3-10x^2-5\ng(x)=2x^3+7x^2-9\nf(x)-g(x)=7x^3-10x^2-5-[2x^3+7x^2-9]\nf(x)-g(x)=7x^3-10x^2-5-2x^3-7x^2+9\nf(x)-g(x)=7x^3-2x^3-10x^2-7x^2-5+9\nf(x)-g(x)=5x^3-17x^2+4$
