For a cylinder having a radius r and a height h ;

Volume Of Cylinder :

Here , the radius of the cylinder is given as 70 cm and the volume is 1.54 m³ .

Converting ;

The height of the cylinder is 100cm.=1m.

The correct answer is,

[tex] \frac{1}{64} [/tex]

Answer:

1/64

Step-by-step explanation:

when exponents are separated by parentheses, multiply them

so (2³)^-2 = 2^-6

whenever an exponent is negative, change into fraction form with one as the numerator and the other term goes into the denominator and the exponent now becomes positive

2^-6 = [tex]\frac{1}{2^6}[/tex] = [tex]\frac{1}{64}[/tex]

Answer:

8y + 7

Step-by-step explanation:

add them: y + 5 + 3y + 5 + 4y - 3 = 8y + 7

Answer:

they have to mix 1.67 quarts 20% and 3.33 quarts 14%

Step-by-step explanation:

Given the data in the question;

let x quarts of the 20 percent alcohol and y quarts of 14 percent alcohol be mixed to form 5 quarts

i.e

x + y = 5  -------------let this be equation 1

20%x + 14%y = 16%5

0.2x + 0.14y = 0.8

multiply through by 50

10x + 7y = 40 -------------let this be equ 2

so let multiply equation by -7

-7x - 7y = -35       ------------- let this be equ 3

add equ 2 and 3

3x + 0 = 5

x = 5/3 ≈ 1.67

substitute value of x in equation 1

5/3 + y = 5

y = 5 - 5/3

y = 10/3 ≈ 3.33

Therefore; they have to mix 1.67 quarts 20% and 3.33 quarts 14%

Answer:

The remainder is 88

Step-by-step explanation:

The Remainder of a Division

We have to find the remainder when we divide 849,400 by 216.

It could be found by doing the long division, but we'll do it with a calculator.

Entering the division in the calculator we get:

849,400/216=3,932.4074...

We take the whole part of the quotient (3,932) and multiply it by the divisor:

3,932*216=849,312

The remainder is obtained by subtracting 849,400-849,312=88

The remainder is 88

Answer:

The first one (Cedric is correct because he used the inverse of subtraction and added 4.5)

Step-by-step explanation:

First....I'll do it my way

z - 4.5 = -1.5

Add 4.5 on both sides

z - 4.5 + 4.5 = -1.5 + 4.5

z = 3

This should be our answer.....and so who did it right?

Cedric did

Which is the true statement?

Cedric is correct because he used the inverse of subtraction and added 4.5

Hope this helped!

Answer:

Step-by-step explanation:

The way to do this (I think) is to figure out the probability of not getting said king on either throw.

First Throw: P(no King Hearts) = 51/52

Second Throw: P(no King Hearts) = 50/51

Total probability = 51/52*50/51 = 50/52

Therefore the probability of getting it right is

P(KH) = 1 - 50/52 = 2/52 = 1/26

I have a feeling that this is not correct. If you get a different answer  that looks reasonable, take it.

Answer:

The number of bagels made in 20 hours is 3100 bagels, at the rate of 155 bagels per hour.

Step-by-step explanation:

Given;

number of bagels in 2 hours = 310 bagels

The rate per hour is calculated as;

[tex]Rate = \frac{310 \ bagels}{2 \ hours}\\\\Rate = 155 \ bagels \ per \ hour[/tex]

In 20 hours, the number of bagels made is calculated as;

Number of bagels = 155 (bagels/hour) x 20 (hour)

                               = 3100 bagels.

Therefore, the number of bagels made in 20 hours is 3100 bagels, at the rate of 155 bagels per hour.

Answer:

2.0 and 4.8

Step-by-step explanation:

each 5 is adding 0.4 and each 10 is adding 0.8. if you take the 20 and the number 1.6, multiply those by 3, and you will get 4.8 for the slot 60. for the slot 25, just add 0.4 to 1.6. hope this helped :)

Answer:

  55 8/39 N ≈ 55 N

Step-by-step explanation:

The net force on the 1.4 kg block is proportional to its mass. That is, the ratio of net force on that block to the net force on the total mass is the same as the ratio of the block's mass to the total mass.

  net force on 1.4 kg = (1.4 kg)/(1.4 +6.4 kg) × (64 N -15 N) = (7/39)(49 N)

  net force on 1.4 kg = 8 31/39 N

Then the force applied by the 6.4 kg mass is ...

  64 N - 8 31/39 N = 55 8/39 N ≈ 55 N . . . . applied by 6.4 kg mass

Answer:

£ 268.2

Step-by-step explanation:

495(1/3)+124(0.5)+(495(2/3)-124)(0.2)=165+62+41.2

                                                            =268.2

Answer: £268.20

Step-by-step explanation:

1/3 of 495 is 165.

124 x .50 = 62.

165 + 124 = 289

495 - 289 = 206

206 x .20 = 41.20

165 + 62 + 41.20 = 268.20

Answer:

Step-by-step explanation:

The null and the alternative hypothesis can be computed as:

[tex]H_o: \mu_{c} \ge \mu_{us}[/tex]

[tex]H_a: \mu_{c} < \mu_{us}[/tex]

The t- student test statistics can be computed as:

[tex]t = \dfrac{ x_c - x_{us} }{\sqrt { \dfrac{\sigma_c^2}{n_c} + \dfrac{\sigma_{us} ^2}{n_{us}} } }[/tex]

[tex]t = \dfrac{ 19 - 21 }{\sqrt { \dfrac{7^2}{100} + \dfrac{8^2}{130} } }[/tex]

t = -2.017

degree of freedom = (n₁-1)+(n₂-1)

= (100-1) + (130-1)

= 228

At t = -2.017 and 228 df

P-value = -0.224

Decision rule: Not to reject the null hypothesis if the p-value is greater than ∝(0.01)

Conclusion: We reject the null hypothesis since the p-value is less than ∝.

Thus, there is sufficient evidence to conclude that the mean age of entering prostitution in Canada is lower than that of the United states.

Following are the solution to the given question:

Step-by-step explanation:

Given:

[tex]\to g(x)= -3+2x^2 \\\\\to f(x)=9-6x[/tex]

Calculating the value of [tex](\frac{g}{f})(2)[/tex]:

[tex]\to (\frac{g}{f}) (2)= (\frac{g(x)}{f(x)}) \times (2)[/tex]

               [tex]=\frac{2x^2-3}{9-6x} \times 2\\\\=\frac{2\cdot 2^2-3}{3(3-2\cdot 2)} \\\\=\frac{2\cdot 4-3}{3(-1)}\\\\ =\frac{8-3}{-3}\\\\ =\frac{5}{-3}\\\\ = - \frac{5}{3}\\\\[/tex]
