Answer:

165.6 cubic yards

Step-by-step explanation:

Given data

Diameter= 5.2yd

Radius= 5.2/2= 2.6yd

Height= 7.8 yd

The expression for the volume of a cylinder is given as

Volume= πr^2h

Substitute

Volume= 3.142*2.6^2*7.8

Volume= 3.142*6.76*7.8

Volume= 165.6 cubic yards

Answer:

The volume of 1 bucket is 2.4 liters.

Step-by-step explanation:

We know that the volume of 12 buckets is the same as the volume of 9 bottles:

[tex] 12B = 9b [/tex]  

[tex] B = \frac{9}{12}b = \frac{3}{4}b [/tex]   (1)

Where B is for buckets and b is for bottles.

Also, that the total volume of 3 bottles and 5 buckets is 21.6 liters:

[tex] 5B + 3b = 21.6 [/tex]   (2)

We can calculate the volume of 1 bucket by entering equation (1) into (2):

[tex] 5(\frac{3}{4}b) + 3b = 21.6 [/tex]

By solving for "b" we have:

[tex] b = \frac{21.6*4}{27} = 3.2 [/tex]

Now, the volume of 1 bucket is:

[tex] B = \frac{3}{4}b = \frac{3*3.2}{4} = 2.4 [/tex]

Therefore, the volume of 1 bucket is 2.4 liters.

I hope it helps you!

Answer:

Sidney played 5 games and rode 8 rides.

Step-by-step explanation:

Since Sydney is going to a carnival that has games and rides, and each game costs $ 1.25 and each ride costs $ 2.25. Sydney spent $ 24.25 altogether at the carnival and the number of rides she went on is 3 more than the number of games she played, to determine the number of games Sydney played and the number of rides Sydney went on the following calculation must be performed:

5 x 2.25 + 2 x 1.25 = 11.25 + 2.50 = 13.75

6 x 2.25 + 3 x 1.25 = 13.50 + 3.75 = 17.25

7 x 2.25 + 4 x 1.25 = 15.75 + 5 = 20.75

8 x 2.25 + 5 x 1.25 = 18 + 6.25 = 24.25

Therefore, Sidney played 5 games and rode 8 rides.

Answer:

x = 12 , x = 7

Step-by-step explanation:

x-2 = 10

x= 10+2 = 12

x+6 = 13

x=13-6

x=7

Answer:

x = 9.5

If they were separate equations,

x - 2 = 10 ⇒ x = 12

x + 6 = 13 ⇒ x = 7

Step-by-step explanation:

x - 2 + x + 6= 10 + 13

2x + 4 = 23

2x + 4 - 4 = 23 - 4

2x = 19

2x ÷ 2 = 19 ÷ 2

x = 9.5

If they were separate,

x - 2 = 10

x - 2 + 2 = 10 + 2

x = 12

x + 6 = 13

x + 6 - 6 = 13 - 6

x = 7

Answer:

151 students must be selected.

Step-by-step explanation:

We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:

[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]

Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].

That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.

Now, find the margin of error M as such

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.

The population standard deviation is known to be $25.

This means that [tex]\sigma = 25[/tex]

How many students must be randomly selected to estimate the mean weekly earnings of students at one college? Sample mean within $4 of the population mean

This is n for which M = 4. So

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]4 = 1.96\frac{25}{\sqrt{n}}[/tex]

[tex]4\sqrt{n} = 1.96*25[/tex]

[tex]\sqrt{n} = \frac{1.96*25}{4}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96*25}{4})^2[/tex]

[tex]n = 150.1[/tex]

Rounding up:

151 students must be selected.

Step-by-step explanation:

tan B = AC/BC

tan 35°= AC / 160

0.700 = AC /160

=> AC = 160 × 0.700

AC = 112.00

so, the distance from A to C is 112.00 feet

From the triangle given in the figure,

Since, adjacent side BC of the right triangle ACB is given and we have to find the opposite side AC of angle ABC,

Trigonometric ratio to be used → [tex]\text{tan}\theta = \frac{\text{Opposite side}}{\text{Adjacent side}}[/tex]

By substituting these values in the expression,

[tex]\text{tan}(35^{\circ}) = \frac{AC}{160}[/tex]

AC = 160[tan(35)°]

AC = 112.03 feet

               Therefore, distance between A and C is 112.03 feet.

Answer:

$337.50

Step-by-step explanation:

Given that

The amount is $11,250

And, the sales terms are 5/10, 3/15, n/30

5/10 means if the payment is done within 10 days so 5% discount is given

3/15 means if the payment is done within 15 days so 3% discount is given

And, n/30 means the credit days for payment allowed is 30

Now the cash discount if the invoice is paid on June 20 is

= $11,250 × 3%

= $337.50

Answer:

A conversion factor is a number used to change one set of units to another, by multiplying or dividing. When a conversion is necessary, the appropriate conversion factor to an equal value must be used. For example, to convert inches to feet, the appropriate conversion value is 12 inches equal 1 foot.

y= 3/5x+5

Step-by-step explanation:

The y intercept is 5 and the graph is going upwards so it is a postive slope. If you look at at the graph from the y intercept point to point B you can see it goes up by 3 and right by 5 so the slope is 3/5. This makes the equation y=3/5x+5
