If a tennis ball has a diameter of 14, What is the volume of the tennis ball? Round to the nearest hundreth Use
3.14 for it pi
if its diameter is 14, then its radius is half that or 7.
[tex]\textit{volume of a sphere}\\\\ V=\cfrac{4\pi r^3}{3}~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=7 \end{cases}\implies \begin{array}{llll} V=\cfrac{4\pi (7)^3}{3}\implies V=\cfrac{1372\pi }{3} \\\\\\ \stackrel{using~\pi =3.14}{V\approx 1436.03} \end{array}[/tex]
Answer:
[tex]1436.76... units^3[/tex]
Step-by-step explanation:
Recall the formula for the volume of a sphere.
[tex]V = \frac{4}{3} \pi r^3[/tex]
The question gives you diameter. As you know, diameter is twice the radius. Therefore, to convert diameter into radius, you divide the diameter by 2.
[tex]r = 14/2[/tex] [tex]= 7[/tex]
Now that you have the radius, all you need to do is plug it into the volume formula.
[tex]V = \frac{4}{3}\pi 7^3[/tex] = [tex]1436.76... units^3[/tex]

Find the value of cos F rounded to the nearest hundredth, if necessary
Using the trigonometric ratios, the value of cos F in the right angle triangle is 0.28 .
What are right angle triangle?Right angle triangle are triangle that has one of its angles as 90 degrees. The sides and angles can be found using trigonometric ratios.
Therefore,
cos F = adjacent / hypotenuse
adjacent = FE
hypotenuse = 50
50² - 48² = FE²
FE = √2500 - 2304
FE = √196
FE = 14
Therefore,
cos F = 14 / 50
cos F = 0.28

Old-fashioned oatmeal contains 27 grams of carbohydrates per 1/2 cup of dry oats. How many grams of carbohydrates are available in 2 1/4 cups of dry oats?
There 121.50 grams of carbohydrates are available in 2 1/4 cups of dry oats.
What is Ratio?The ratio is defined as a relationship between two quantities, it is expressed as one divided by the other.
We have been given that old-fashioned oatmeal contains 27 grams of carbohydrates per 1/2 cup of dry oats.
We have to determine the number of grams of carbohydrates available in 2 1/4 cups of dry oats.
Let x grams of carbohydrates be available in 2 1/4 cups of dry oats.
As per the given information, we can write the ratio would be as:
27 grams of carbohydrates : 1/2 cup of dry oats = x grams of carbohydrates : 2 1/4 cup of dry oats
⇒ 27/ (1/2) = x/(2 1/4)
⇒ 27/ (1/2) = x/(9/4)
Reciprocal the term in the numerator,
⇒ 27 × 2 = x × 4/9
Apply the cross-multiplication operation,
⇒ x = 54 × 9/4
⇒ x = 121.50
Thus, there are 121.50 grams of carbohydrates are available in 2 1/4 cups of dry oats.

Answer:
162
Step-by-step explanation:
to find the surface area of the rectangles do base x height
5 x 10 = 50
there are 3 sides on a triangle so do 50 x 3 = 150
now we need to find the area of the triangles
the formula for the surface area would be base x height ÷ 2
3 x 4 = 12
12 ÷ 2 is 6
because there are 2 triangles you would need to multiply it by 2
6 x 2 is 12
add it all together
12 + 150 is 162

A company paid $203.00 for an item. The original price was $291.10, but this was marked down 40%. If the operating expenses are 36% of the cost, find the operating loss and the absolute loss.
1. What is the operating loss?
2. What is the absolute loss?
Answer,:
Answer and Explanation: 1
1.
Calculation for operating loss is shown below:
Break-even point in dollars = Cost + Operating expenses
Break-even point in dollars = $208.40 + (36% * $208.40)
Break-even point in dollars = $208.40 + $ 75.024
Break-even point in dollars = $283.424
Reduced price = Original price - (Original price * Mark down)
Reduced price = $292.60 - ($292.60 * 40%)
Reduced price = $292.60 - $117.04
Reduced price = $175.56
Operating loss = Break-even point in dollars - Reduced price
Operating loss = $283.424 - $175.56
Operating loss = $107.864
2.
Calculation of absolute loss is shown below:
Absolute loss = Cost - Reduced price
Absolute loss = $208.40 - $175.56
Absolute loss = $32.84

What is an exponential function?Exponential function is the function in which the function growth or decay with the power of the independent variable. The curve of the exponential function depends on the value of its variable.
The exponential function with dependent variable y and independent variable x can be written as,
[tex]y=ab^x[/tex]
Here, x is the variable in the power of a number.
State the equation of the exponential function that has the following features.
It has the x-axis as an asymptote.It passes through (0,—1), (—1,—3), and (—2,—9). For the point (0,-1)[tex]-1=ab^{(0)}\\-1=a\times1\\a=-1[/tex]
For the point (-1,-3)
[tex]-3=ab^{(-1)}\\-3=\dfrac{a}{b}\\[/tex]
Put, the value of -1 in the above equation,
[tex]-3=\dfrac{-1}{b}\\b=\dfrac{1}{3}[/tex]
Thus, the exponential function,
[tex]y=-1(\dfrac{1}{3})^x\\y=-\left (\dfrac{1}{3}\right)^x[/tex]
Hence, an exponential function that has the x-axis as an asymptote and It passes through (0,—i), (—1,—3), and (—2,—9) is y=-(1/3)ˣ.

rom the sample space S={1, 2, 3, 4,..., 15} a single number is to be selected at random. Given the following events, find the indicated probability. A: The selected number is even. B: The selected number is a multiple of 4. C: The selected number is a prime number. P(C∣A)
The probability that the selected number is even, multiple of 4 and prime are 7/15, 1/5 and 2/5 respectively
What is Probability?Probability is the likelihood or chance that an event will occur.
Probability = Expected outcome/Total outcome
Given the following set
S={1, 2, 3, 4,..., 15}
n(S) = 15
If the selected number is even
E = {2, 4, 6, 8, 10, 12, 14}
n(E) = 7
Pr(selecting even number) = n(E)/n(S)
Pr(selecting even number) = 7/15
If the selected number is a multiple of 4
E = {4, 8, 12}
n(E) = 3
Pr(multiple of 4) = n(E)/n(S)
Pr(multiple of 4) = 3/15 = 1/5
If the selected number is a prime number
E = {2, 3, 5, 7, 11, 13}
n(E) = 6
Pr(prime number) = n(E)/n(S)
Pr(prime number) = 6/15 = 2/5

Step 1: Figure out how many years 2020 is after 1998
2020 is 22 years after 1998, therefore we should plug in 22 for x.
Step 2: Plug in known values
The only unknown variables in this equation are S and x. We just found out what x is, which leaves S for us to figure out by solving.
S - 1.5(22) = 5.1
Step 3: Solve
Now, all that's left to do is solve for S.
S - 1.5(22) = 5.1
S - 33 = 5.1
S = 38.1
