We need to find the volume of a cylinder with a diameter of 17 cm and a height of 41 cm.

The volume V of a cylinder with radius r and height h is:

$V=\pi r^2h$

In this problem, we have:

$\begin{gathered} r=\frac{\text{ diameter}}{2}=\frac{17\text{ cm}}{2}=8.5\text{ cm} \\ \\ h=41\text{ cm} \\ \\ \pi\cong3.14 \end{gathered}$

Then, we obtain:

$\begin{gathered} V\cong3.14(8.5\text{ cm})^2(41\text{ cm}) \\ \\ V\cong3.14(72.25)(41)\text{ cm}^3 \\ \\ V\cong9301.465\text{ cm}^3 \end{gathered}$

Answer

The volume is 9301.465 cm³.

Use cross products to demonstrate whether or not the two ratios are equivalent:
4/6 and 14/21.

Answers

cross products: a/b = c/d is also equal to ad = bc

so, essentially you’re just drawing two diagonal lines from one side to the other, multiplying those numbers together, and setting them equal

so: 4/6 and 14/21 = (4*21 = 6*14) = (84 = 84)

84 is equal to 84 so these two ratios are equivalent.

a diver is 19 made it below the surface of the water use an integer to represent how far the diver would need to travel to reach to Surfer

Answers

If the diver is 19 meters below the surface, we can represent the depth as a one-dimension measure, where the surface has a value of 0.

Then, if he is 19 below the surface, he is at x=-19.

He has to travel from x=-19 to the surface (x=0), then the difference is:

Surface - Actual Position = 0 - (-19) = 19

He need to travel 19 meters towards the surface.

What is the measure of the circumference of a circle?

The circumference of a circle of radius r is given by the equation presented as follows:

C = 2πr.

The parameters for this problem are given as follows:

d = 9 -> r = 4.5.

(as the radius is half the diameter)

Hence the circumference is given as follows:

C = 2 x π x 4.5

C = 28.27 ft.

The cost is of $4.22 per ft, hence the total cost is given as follows:

4.22 x 28.27 = $119.30.

Use the expressions from the previous questions to determine Mary’s age.

Answers

The age of Mary is 15 years old.

To solve this, we have three expressions:

$\begin{gathered} M=J+5 \\ J=T-28 \\ T=3H-1 \end{gathered}$

Where M is the age of Mary, J is the age of Jacob, T is the age of Uncle Tim and H is the age of Henry

Also teh problem give us an additional info, the age of Henry is 13. With this, we can replace the value of H in the thrid equation:

$\begin{gathered} \begin{cases}H=13 \\ T=3H-1\end{cases} \\ \text{Then:} \\ T=3\cdot13-1=39-1=38 \\ T=38 \end{gathered}$

Now we can replace T in the second equation:

$\begin{gathered} \begin{cases}T=38 \\ J=T-28\end{cases} \\ \text{Then:} \\ J=38-28=10 \\ J=10 \end{gathered}$

Finally, we can replace J in the first equation to get the age of Mary:

$\begin{gathered} \begin{cases}J=10 \\ M=J+5\end{cases} \\ \text{Then:} \\ M=10+5=15 \end{gathered}$

Thus, the age of Mary is 15 years old.

Answers

Answer:

Mix A ≤ 12

Mix B ≤ 12

Step-by-step explanation:

Mix A requires 3 oz of cashews and 7 oz of almonds

Mix B requires 6 oz of cashews and 5 oz of almonds

If Brenda makes just Mix A using the available 72 oz of cashews and 84 oz of almonds

With 72 oz of cashews, she would potentially make 72/3=24 Mix A snacks

With 84 oz of almond, she would potentially make 84/7=12 Mix A snacks

Since she would require both cashews and almonds to make Mix A snacks, she would be able to make 12 mix A snacks

Inequality would be:

Mix A ≤ 12

If Brenda makes just Mix B using the available 72 oz of cashews and 84 oz of almonds

With 72 oz of cashews, she would potentially make 72/6=12 Mix B snacks

With 84 oz of almond, she would potentially make 84/5=16 (approximately) Mix B snacks

Since she would require both cashews and almonds to make Mix B snacks, she would be able to make 12 mix B snacks

after a few pricing experiments papas fried chicken has determined that the number b of buckets of chicken papa can sell on a saturday night is related to the price p per bucket by the relation b=100-5p what can we tell from this formula

Answers

The formula provides insights into the relationship between price and demand for Papa's Fried Chicken, indicating how changes in price affect the number of buckets of chicken sold.

From the formula b = 100 - 5p, we can infer the following:

The formula represents a linear relationship between the number of buckets of chicken sold (b) and the price per bucket (p).

The coefficient of p, which is -5, indicates that for every increase of 1 unit in the price, the number of buckets sold decreases by 5 units. Conversely, for every decrease of 1 unit in the price, the number of buckets sold increases by 5 units.

The intercept term of 100 represents the maximum number of buckets that can be sold at a price of 0. This suggests that there is a limit to the number of buckets that customers are willing to purchase, regardless of the price.

The formula assumes a downward-sloping demand curve, indicating that as the price increases, the quantity demanded decreases. This aligns with the typical behavior of most goods or services.

The formula implies that there may be an optimal price point where the number of buckets sold is maximized. Finding this price point would involve finding the value of p that maximizes the expression 100 - 5p.

A square has a side length of 7 cm. A rectangle has a length of y/8-3cm and a width of 4 cm. The square has the same perimeter as the rectangle. Work out the value of y.

Answers

if the square has the same perimeter as the rectangle then the value of y is 92.

How to find the value of y?

The perimeter of a square is equal to the sum of all four sides, so a square with a side of 7 cm has a perimeter of 4 * 7 cm = 28 cm.

The perimeter of the rectangle is equal to twice the sum of the length and width. So for a rectangle of length y/8-3cm and width 4cm, the perimeter is 2 * (y/8-3+4) cm = (y/4-3+8) cm = y/4 . +5 cm.

Since squares and rectangles have the same perimeter, the two perimeter formulas can be equal.

28cm = y/4+5cm

You can solve for y by isolating it on one side of the equation.

years/4+5 = 28

y/4 = 23

y=92

So the value of y is 92.

What is the equation of the line that passes through the point (-8,-8)(−8,−8) and has a slope of 0?

Answers

Answer:

$y=-8$

Step-by-step explanation:

Recall the slope formula:

$m=\frac{x_{2} -x_{1}}{y_{2} -y_{1}}$

Since all of the x and y values are -8, we can easily plug in the values.

$m=\frac{-8+8}{-8+8}=0$

(The second -8 on the top and bottom is positive because adding when subtracting negatives, you must add. For example -1-(-1) would become -1+1=0)

Recall the point-slope formula:

$y-y_{1} = m(x-x_{1} )$

Now substitute and solve.

$y-(-8)=0(x-(-8)$ Substitute

$y+8=0(x+8)$ Simplify

$y+8=0$ Distributive Property

$y=-8$ Subtraction Property

Therefore the answer is $y=-8$.
