The volume of the resulting ring is (4/3)π(R³ - r³)

The volume of an object is the amount of space occupied by the object in three dimension.

The volume (V) of a sphere is given by:

V = (4/3)πr³

Where r is the radius of the sphere.

For the sphere with radius R, volume is:

V = (4/3)πR³

The hole with radius r, has a volume of:

V = (4/3)πr³

Hence volume of the ring = (4/3)πR³ - (4/3)πr³ = (4/3)π(R³ - r³)

The volume of the resulting ring is (4/3)π(R³ - r³)

Answer:

1.7 x 10= 17 (moving one decimal point to the right)

1.7 x 100=170 (moving two decimal points to the right)

1.7 x 1000= 1700 (moving 3 decimal points to the right)

Reflect: The decimal changes depending on the number of zeros in each multiple of ten that it is multiplied by. If it is multiplied by 10 for instance, the decimal is moved one place to the right since there is one 0, if by 100 then it is moved two places to the right since there are 2 zeros, and if by 1000 then it is moved 3 places to the right for the 3 zeros.

Step-by-step explanation:

The question to the awnser is how much can 10 go into 50. That means you have to divide 50 by 10. You can put 10 5 times into 50, and you can make sure of that by timing 10 by 5. I have no idea though what you need. Sorry if im saying somthing different than wht you want.

Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.

The together rate is the sum of each separate rate.

In this problem, the rates are:

Hence:

[tex]\frac{1}{12} + \frac{1}{x} = \frac{1}{8}[/tex]

[tex]\frac{x + 12}{12x} = \frac{1}{8}[/tex]

[tex]12x = 8x + 96[/tex]

[tex]4x = 96[/tex]

Answer:

$9.10 dollars

Step-by-step explanation:

The original price of the shoes is $6.50, so we want to add 40% to that. There are two ways to do this.

Method 1:

Find 40% of 6.50, and add it to 6.50.

[tex]6.5*0.4= 2.6\\6.5+2.6=9.1[/tex]

Method 2:

Multiply 6.5 by 1.4 (including the original percent of 100 and adding 40 percent to it)

[tex]6.5*1.4=9.1[/tex]

Answer:

D. -8.1

Step-by-step explanation:

Squares of natural numbers are

{1,4,9,16,25,36,49,64,81,...}, which are squares of {1,2,3,4,5,6,7,8,9,....}

As 65 lies between 64 and 81, square root of

65 lies between 8 and 9 Further, 8.1 2 = 65.61, and as 8.02 = 64, the square root of 65 lies between 8.0 and 8.1.

We have,

[tex]\sf{ HE = 2x cm \: and \: OR = ( x + 5)cm}[/tex]

We know that,

From above property,

[tex]\sf{ HE = OR }[/tex]

[tex]\sf{ 2x = x + 5}[/tex]

[tex]\sf{ 2x - x = 5}[/tex]

[tex]\sf{ x = 5}[/tex]

Thus, The value of x is 5cm

Therefore,

The value of HE

[tex]\sf{ = 2x}[/tex]

[tex]\sf{ = 2× 5}[/tex]

[tex]\sf{\red{ = 10 cm}}[/tex]

The measurement of HE is 10 cm

Hence, Option A is correct

We have,

[tex]\sf{m}{\sf{\angle{HER = 5y - 26° \: and\: m }}}{\sf{\angle{ ROH = 2y + 40°}}}[/tex]

From above property,

[tex]\sf{m}{\sf{\angle{HER = }}}{\sf{\angle{ ROH}}}[/tex]

[tex]\sf{ 5y - 26° = 2y + 40°}[/tex]

[tex]\sf{ 5y - 2y = 40 + 26}[/tex]

[tex]\sf{ 3y = 40 + 26}[/tex]

[tex]\sf{ y = 66/3}[/tex]

[tex]\sf{ y = 22°}[/tex]

Thus, The value of y is 22°

Therefore,

The measurement of Angle HER

[tex]\sf{ = 5 × 22 - 26 }[/tex]

[tex]\sf{ = 110 - 26 }[/tex]

[tex]\sf{\red{= 84° }}[/tex]

The measurement of angle HER is 84°

Hence option D is correct

We have,

[tex]\sf{ HZ = 4a - 5 \:and \:RZ = 3a + 5 }[/tex]

[tex]\sf{ 4a - 5 = 3a + 5 }[/tex]

[tex]\sf{ 4a - 3a = 5 + 5}[/tex]

[tex]\sf{ a = 10}[/tex]

Thus, The value of a is 10

Therefore,

The measurement of HZ

[tex]\sf{ = 4 × 10 - 5 }[/tex]

[tex]\sf{ = 40 - 5 }[/tex]

[tex]\sf{\red{= 35 \: cm }}[/tex]

The measurement of HZ is 35 cm

Hence, Option C is correct

We have ,

One diagonals = 5x - 47

Another diagonal = 2x + 34

From above property,

[tex]\sf{ 5x - 47 = 2x + 34 }[/tex]

[tex]\sf{ 5x - 2x = 34 + 47}[/tex]

[tex]\sf{ 3x = 81 }[/tex]

[tex]\sf{ x = 81/3 }[/tex]

[tex]\sf{ x = 27}[/tex]

Thus, The value of x is 27

Hence, Option A is correct

We have,

The sides of parallelogram GAME are (7x - 1 ) , ( 5x + 10 ) , (6x) , ( 7x - 2 )

From above property,

[tex]\sf{ 7x - 1 = 6x }[/tex]

[tex]\sf{ 7x - 6x = 1 }[/tex]

[tex]\sf{ x = 1 }[/tex]

[tex]\sf{ 5x + 10 = 7x - 2}[/tex]

[tex]\sf{ 7x - 5x = 10 + 2 }[/tex]

[tex]\sf{ 2x = 12}[/tex]

[tex]\sf{ x = 12/2 }[/tex]

[tex]\sf{ x = 6 }[/tex]

Thus, measurements of parallelogram GAME in inches is 1 and 6 .

Hence, Option B is correct

We have,

[tex]\sf{ ES = 18 cm}[/tex]

From above we can say that,

[tex]\sf{ OE = OS + ES }[/tex]

[tex]\sf{ OE = 2ES ( OS = ES bisector}[/tex]

[tex]\sf{ OE = 2 × 18 }[/tex]

[tex]\sf{ OE = 36cm }[/tex]

Thus, The value of OE is 38 cm

Therefore,

[tex]\sf{ OE = NP }[/tex]

[ Diagonals of the given rectangle ]

[tex]\sf{\red{NP = 36 cm }}[/tex]

Thus , The value of NP is 36 cm

Hence, Option C is correct

Answer:

On the first day of July he will need to have saved $4098 for his new car.

Step-by-step explanation:

So we know that on March he save $16 and the amount he needs to save each month increases by 4 times the previous month’s amount.

We can conclude then for April he would need to have saved $64.

In May, if we repeat the pattern of multiplying the previous month’s savings by 4, Warren would have saved $256.

We will continue this pattern for June and July.

In July we will multiply $1024 (total saved in June) by 4 to find that in July, Warren will have needed to save $4098

It will take the turkey about 3 hours to roast.

Total no of customers = 500

Used coupon = 120

Not used coupon = 500 - 120 = 380

We need to find the percentage of the customers do not use a coupon. It can be given by :

380/500×100

So, there are 76% of the customers that do not use a coupon.

Answer:

y = 14  x = 2

Step-by-step explanation:

what we know:

x + y = 16

x = 3y - 40

3y - 40 + y = 16

4y - 40 = 16

add 40 to both sides

4y = 56

y = 14

x = 3(14) - 40

x = 42 - 40

x = 2

Answer:

40% chance of success

Step-by-step explanation:

The possible integers chosen are 0, 1, 2, 3, and 4.

Since the numbers are randomly chosen and the numbers 2 and 3 represent a success, and the numbers 0, 1, and 4 represent a failure, and there are 5 possible outcomes, there is a 2/5 chance of success. Therefore, you have an estimated 40% chance of a success.
