Answer:

The volume (V) of a cylinder is calculated by the formula:

V = \pi r^2h    ....[1]

Here, r denotes the cylinder's radius, and h is its height.

From the image provided:

The pipe's diameter (d) = 10 cm

The length (height) of the pipe (h) = 2 m

Convert units:

Since 1 m = 100 cm, then

2 m = 200 cm

So, h = 200 cm

Because the pipe resembles a cylinder,

we must find its volume.

Recall that:

d = 2r

Thus,

10 = 2r

Dividing both sides by 2 yields;

5 = r

or

r = 5 cm

Plug the values into equation [1] and use π = 3.14:

V = 3.14 \cdot 5^2 \cdot 200

Simplifying gives:

V = 15,700 cm^3

Hence, the volume of the pipe is 15,700 cm³.

Five more than twice a number is three times the difference of that number and two. What is the number.
Zina [12190]

Response:

2(3-n)+5.

Clarification:

Twice a number plus five equals three times the difference between that number and two. "More" indicates addition, hence twice the number is represented as multiplying N (or whatever variable) with the determination that it equals three times the reduction of that number and two.

Yolanda invests $30,000 in an account that offers a compound interest rate of 7.9% per year. Which of the following is the corre
Zina [12190]
To find the solution, we will utilize the compound interest formula: A=P(1+ \frac{r}{n} )^{nt}
where
A represents the total amount after t years
tex]P[/tex] indicates the original investment 
r signifies the interest rate expressed in decimal
n shows the frequency of compounding per year
t indicates the duration in years

According to our problem, the initial investment is <span>$30,000 with a duration of ten years, thus </span>P=30000 and t=10. Interest is compounded annually, so n=1. To convert the percentage interest rate into decimal, we divide it by 100%
r= \frac{7.9}{100}
r=0.079
Now, we can insert these values into our formula:
A=P(1+ \frac{r}{n} )^{nt}
A=30000(1+ \frac{0.079}{1} )^{(1)(10)}
A=3000(1+0.079)^{10}
Substituting A with P_{10}:
P_{10}=3000(1+0.079)^{10}

Consequently, we find that the correct answer is D. P_{10}=3000(1+0.079)^{10}

Finally, to determine <span>the total amount Yolanda will have after ten years, we just need to carry out the operations in our equation: 
</span>P_{10}=3000(1+0.079)^{10}
P_{10}=30000(1.079)^{10}
P_{10}=64170.54

Thus, we conclude that Yolanda will end up with $64,170.54 in her account after a decade of earning <span>at a compound interest rate of 7.9% yearly.</span>

Find the lateral area of the prism.<br><br> 120 sq. in.<br> 150 sq. in.<br> 720 sq. in.
Inessa [12311]

To determine the lateral area of the pentagonal prism illustrated in the figure, we begin the calculation.

According to the definition:

A_ {l} = P_ {b} * h

Where:

A_{l}: Represents the lateral area

P_ {b}: Refers to the perimeter of the base

h: Denotes the height

By substituting the known values:

A_ {l} = 20 \ in * 6 \ in\\A_ {l} = 120 \ in ^ 2

Result:

A_ {l} = 120 \ in ^ 2

A survey conducted five years ago by the health center at a university showed that 18% of the students smoked at the time. This
tester [12079]
The test statistic (Z) is 2.5767, and the p-value of the test is 0.009975. The null hypothesis suggests that the smoking rate among students has not changed, while the alternative indicates otherwise. The z-statistic for the sampled proportion is computed, yielding z ≈ 2.5767. As we investigate whether the smoking percentage has shifted over the preceding five years, the two-tailed p-value is found to be 0.009975. This result is significant at a 99% confidence level, demonstrating substantial evidence that the percentage of smoking students has changed.
