Step-by-step explanation:

Surface area of a cylinder
A = 2πr(h+r)

where r = radius, h = height

Here

r = diameter/w = 8/2 = 4 feet

h = 8 feet

A = 2π · 4 (8 + 4)

= 8π (12)

= 96π cubic feet

Answer:

17.

Step-by-step explanation:

[tex]a^2+b^2 = c^2[/tex] is the formula used to find the hypotenuse (also known as the Pythagora's Theorem).

Substitute the given values into the equation.

[tex]8^2+15^2=c^2[/tex]

64 + 225 = [tex]c^2[/tex]

289 = [tex]c^2[/tex]

[tex]\sqrt{289}[/tex] = c

If a curve passes through the point (0,5) and has the property that the slope of the curve at every point P is twice the y-coordinate of P.  The equation of the curve is  y = 5e^(²x).

Let's assume that the equation of the curve is y = f(x), where f(x) is some unknown function.

We are given that the slope of the curve at every point P is twice the y-coordinate of P. This means that:

f'(x) = 2f(x)

where:

f'(x) is the derivative of f(x) with respect to x.

We can solve this differential equation by separating the variables and integrating:

1/f(x) df/dx = 2

Integrating both sides with respect to x, we get:

ln|f(x)| = 2x + C

where C is a constant of integration.

To find the value of C, we can use the fact that the curve passes through the point (0,5). Substituting x=0 and y=5 into the equation, we get:

ln|f(0)| = C

Since ln|f(0)| is just a constant, we can write it as another constant, say A. Therefore:

ln|f(x)| = 2x + A

Taking the exponential of both sides, we get:

|f(x)| = e^(²x+A)

Since f(x) cannot be negative (otherwise, the slope of the curve would be negative at some points), we can drop the absolute value signs:

f(x) = e^(²x+A)

To find the value of A, we can use the fact that the curve passes through the point (0,5). Substituting x=0 and y=5 into the equation, we get:

f(0) = e^A = 5

Therefore, A = ln(5). Substituting this value into the equation, we get:

f(x) = e^(²x+ln(5)) = 5e^(²x)

So the equation of the curve is y = 5e^(²x).

The quantity of fuel utilized by the water tanker in March 2022 is 10,580 litres. The total amount of money that was utilized on fuel for the water tanker in March 2022 is R206,929.00.

To determine the quantity of fuel utilized by the water tanker in March 2022, we need to first calculate the total distance that the water tanker has covered in March 2022.

The total distance covered can be calculated using the formula:

distance = rate × time

From Annexure A, we can see that the water tanker was supplied to the construction site on the following dates in March 2022:

March 1, 2, 3, 6, 7, 8, 9, 10, 13, 14, 15, 16, 17, 20, 21, 22, 23, 24, 27, 28, 29, 30, and 31

Counting the number of days, we get a total of 23 days. Since the water tanker was supplied every day, we can assume that it covered the same distance every day.

The rate of fuel consumption of the Mercedes water tanker averages 5 km/l, which means that it can travel 5 km for every litre of fuel it consumes. Therefore, the distance covered by the water tanker on a full tank of fuel is:

distance = rate × fuel capacity

= 5 km/l × 460 litres

= 2300 km

So, the total distance covered by the water tanker in March 2022 is:

distance = 23 days × 2300 km/day

= 52,900 km

Next, we can determine the quantity of fuel utilized by the water tanker in March 2022 using the formula:

quantity of fuel = distance ÷ rate

Using the values we have calculated, we get:

quantity of fuel = 52,900 km ÷ 5 km/l

= 10,580 litres

Therefore, the quantity of fuel utilized by the water tanker in March 2022 is 10,580 litres.

To determine the total amount of money that was utilized on fuel for the water tanker in March 2022, we can multiply the quantity of fuel utilized by the fuel price in March 2022:

total cost = quantity of fuel × fuel price

From the problem statement, the fuel price in March 2022 was R19.55 per litre. Substituting the values we have calculated, we get:

total cost = 10,580 litres × R19.55/litre

= R206,929.00

Therefore, the total amount of money that was utilized on fuel for the water tanker in March 2022 is R206,929.00.

Complete question:

Records of the number of water tankers that were supplied to the construction site appear in the calendar on ANNEXURE A. The water tanker has a fuel capacity of 460 litres. The rate of fuel consumption of the Mercedes water tanker averages 5 km/l. The prices of fuel per litre in March and June 2022 appear below.

Answer: the circumference of Jill's pie is 31.4 inches.

Step-by-step explanation:

The circumference (C) of a circle is given by the formula C = πd, where d is the diameter of the circle and π (pi) is a constant approximately equal to 3.14.

In this case, the diameter of Jill's pie is 10", so we can use the formula to find the circumference:

C = πd

C = 3.14 x 10

C = 31.4 inches

Therefore, the circumference of Jill's pie is 31.4 inches.

Answer:

10pi or 31.42

Step-by-step explanation:

the formula for circumference of a circle is 2pir (yes, i can't find the symbol for pi... sorry...) (and r = the radius)

since the diameter is 2*r, the radius is 5 inches.

2*5*pi = 10pi, which is about 31.42

The answer to given linear equation will be When y = 200, x = 8.82.

The values of x and y utilised will determine the solution to the equation y = 11.7x + 96.7.

You can solve for y by substituting a particular value of x into the equation. For instance, if x equals 2, then:

y = 11.7(2) + 96.7

y = 23.4 + 96.7

y = 120.1

Hence, at x = 2, y = 120.1.

Nevertheless, you might choose a different value of y and solve for x by substituting it into the equation. For instance, if y equals 200, then

200 = 11.7x + 96.7

103.3 = 11.7x

x = 8.82

Hence, x equals 8.82 when y is 200.

The number of students are 110 students offer Biology but not Mathematics.

Let's use a Venn diagram to solve this problem. We know that 125 students offer Biology and 110 offer Mathematics, and we want to find out how many offer Biology but not Mathematics.

First, we can fill in the number of students who offer both Biology and Mathematics, which is the overlap between the two circles. We can do this by subtracting the total number of students who offer both from the total number of students who offer either:

220 (total) - (125 + 110) = 220 - 235 = -15

Wait a minute! A negative number of students doesn't make sense in this context. What this tells us is that there must be some double-counting going on - in other words, some students are being counted twice, once in each of the Biology and Mathematics categories.

To correct for this, we need to add back in the number of students who are counted twice, which is the overlap between the two circles. We can calculate this by adding the number of students who offer Biology and Mathematics together:

125 + 110 = 235

Now we can redo the calculation:

220 (total) - 235 (double-counted) = -15

This tells us that there are 15 students who are being counted twice. To find the number of students who offer Biology but not Mathematics, we need to subtract this number from the number of students who offer Biology:

Answer: if im correct i think its 95

The simple interest has an expression and the total amount after an year at an interest rate of 4.5% is approximately $2478.33. The value of R(x) after 6 years is 275 and the new expression for A(x) is 525x^5 + 450x^4 + 375x^3 + 500x^2 + 300x + 275

1. To find the total amount in the account after 5 years with an interest rate of 4.5%, we can simply plug in x = 1.045 (1 + 0.045) into the expression for A(x):

A(1.045) = 525(1.045)^5 + 450(1.045)^4 + 375(1.045)^3 + 500(1.045)^2 + 300(1.045)

≈ 2478.33

So the total amount in the account after 5 years with an interest rate of 4.5% is approximately $2478.33

2. After 6 years, the expression for A(x) would become:

A(x) + 275

We can find the new expression for R(x) by subtracting the original expression for A(x) from the new expression:

R(x) = A(x) + 275 - A(x)

= 275

So the new expression for R(x) after 6 years is simply R(x) = 275.

3. The original expression for A(x) was:

A(x) = 525x^5 + 450x^4 + 375x^3 + 500x^2 + 300x

To find the new expression for A(x) after 6 years, we can simply plug in x = 1.045 (1 + 0.045) and add 275:

A(1.045) + 275 = 525(1.045)^5 + 450(1.045)^4 + 375(1.045)^3 + 500(1.045)^2 + 300(1.045) + 275

≈ 2923.97

So the new expression for A(x) after 6 years is:

A(x) = 525x^5 + 450x^4 + 375x^3 + 500x^2 + 300x + 275

6/23 is the value of x that ensures that the equation 23x + 5 = 11 holds true. The solution to this problem cannot be found in the available selections since none of the answer possibilities match this value.

We must find x in order to determine what value of x results in the equation 23x + 5 = 11 being true.

Initially, we must remove 5 from both sides of the equation to isolate the variable x:

23x + 5 - 5 = 11 - 5

When we combine the left and right sides, we obtain:

23x = 6

Then, by multiplying both sides of the equation by 23, we must find x:

23x/23 = 6/23

When we combine the left and right sides, we obtain:

Based on the sample of 37 sandwich cookies, it can be concluded that the average weight of a sandwich cookie is close to 11.3 grams, as the manufacturer claimed. This conclusion is supported by the mean, standard deviation, and range of the sample.

Standard deviation is a measure of how spread out a set of numbers is. It gives us an idea of how much variation there is from the average or expected value. It is calculated by taking the square root of the variance, which is the average of the squared differences from the mean.

The manufacturer of a sandwich cookie claims that the average weight of a sandwich cookie is 11.3 grams. To test this claim, a statistics class randomly selected 37 sandwich cookies and weighed them. The sample of 37 sandwich cookies had a mean of 11.2 grams, standard deviation of 0.5 grams, and range of 10.1 to 12.5 grams.

The mean of 11.2 grams is very close to the manufacturer’s claim of 11.3 grams. The standard deviation of 0.5 grams indicates that the sample of sandwich cookies had a very small amount of variance. The range of 10.1 to 12.5 grams indicates that the sample had sandwich cookies with weights that were close to the mean, which further supports the conclusion that the mean is close to 11.3 grams.

On replacing the incandescent light bulb with a fluorescent light bulb (a) the energy saved in one day is 0.22 kWh, (b) the energy saved in one year is 80.3 kWh. and (c) the cost savings in one year is $8.03.

a. The energy saved in one day by using the fluorescent light bulb instead of the incandescent light bulb can be calculated as follows:

Energy saved in one day = Energy consumed by incandescent bulb - Energy consumed by fluorescent bulb

Energy saved in one day = (75 watts x 4 hours) - (20 watts x 4 hours)

Energy saved in one day = 300 watt-hours - 80 watt-hours

Energy saved in one day = 220 watt-hours

To convert watt-hours to kilowatt-hours (kWh), we divide the watt-hours by 1000:

Energy saved in one day = 220 watt-hours / 1000

Energy saved in one day = 0.22 kWh

b. The energy saved in one year by using the fluorescent light bulb instead of the incandescent light bulb can be calculated as follows:

Energy saved in one year = Energy saved in one day x Number of days in one year

Energy saved in one year = 0.22 kWh/day x 365 days/year

Energy saved in one year = 80.3 kWh

c. The cost savings in one year by using the fluorescent light bulb instead of the incandescent light bulb can be calculated as follows:

Cost savings in one year = Energy saved in one year x Cost per kWh
