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)

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:

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.

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,

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)

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.

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:

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

Hope this helps you out :)

Answer:262144

Step-by-step explanation:

If your doing this on savvas for school this will be the answer not the other

Step-by-step explanation:

Given that:

{(x²+y²)/(x²-y²)} = 17/8

On applying cross multiplication then

since, (a/b) = (c/d) ⇛a(d) = b(c)

Where, x = x²+y², b = x²-y², c = 17 and d = 8

So,

⇛17(x²-y²) = 8(x²+y²)

Multiply the number outside of the brackets with variables in the brackets on both LHS and RHS.

⇛17x²-17y² = 8x²+8y²

⇛17x²-17y² - 8x²-8y² = 0

⇛17x²- 8x² - 17y² - 8y² = 0

⇛9x² - 25y² = 0

⇛9x² = 25y²

⇛9/25 = y²/x²

⇛25/9 = x²/y²

⇛x/y = √(25/9)

⇛x/y = √{(5*5)/(3*3)}

⇛x/y = 5/3

Therefore, x:y = 5:3

Let x = 5a and y = 3a

Now, (x³+y³):(x³-y³)

= {(x³+y³)/(x³-y³)} = [{(x+y)(x²-xy+y²)}/{(x-y)(x²+x-y+y²)}]

= [{(5a)³ + (3a)³}/{(5a)³ - (3a)³}]

= [{(5*5*5*a*a*a) + (3*3*3*a*a*a)}/{(5*5*5*a*a*a) - (3*3*3*a*a*a)}]

= {(125a³ + 27a³)/(125a³ - 27a²)}

= {(152a³)/(98a³)}

= 152/98

Write the obtained fraction in lowest form by cancelling method.

= {(152÷2)/(98÷2)}

= 76/49

Therefore, , (x³+y³):(x³-y³) = 76/49

Answer: Hence, the required value of (x³+y³):(x³-y³) is 76/49.

Please let me know if you have any other questions.

Answer:

  76:49  or  49:76

Step-by-step explanation:

The second relation gives an expression for y in terms of x:

  [tex]\dfrac{x^2+y^2}{x^2-y^2}=\dfrac{17}{8}\\\\8x^2+8y^2=17x^2-17y^2\qquad\text{cross multiply}\\\\25y^2=9x^2\qquad\text{add $(17y^2-8x^2)$}\\\\5y=\pm3x\qquad\text{take the square root}\\\\y=\pm\dfrac{3}{5}x\qquad\text{divide by 5}[/tex]

Substituting into the expression we want the value of, we can factor out x^3 to get ...

  [tex](x^3+y^3):(x^3-y^3)=(1\pm(3/5)^3):(1\mp(3/5)^3)=(125\pm27):(125\mp27)\\\\=152:98\text{ or }98:152=\boxed{76:49\text{ or }49:76}\m[/tex]
