Find the volume of a sink
Volume sink=(4/6)*pi*r³ (half-sphere)
Diameter=20 in--------------> r=D/2-----------> r=10 in
Volume sink=(4/6)*pi*10³---------> (2000/3)*pi in³ --------> 2093.33 in³
(a) What is the exact volume of the sink?
the answer part a) is (2000/3)*pi in³ (2093.33 in³)
(b) One conical cup has a diameter of 8 in. and a height of 6 in. How many cups of water must Ki’von scoop out of the sink with this cup to empty it?
volume of a conical cup=pi*r²*h/3
diameter=8 in--------------> r=4 in
h=6 in
volume of a conical cup=pi*4²*6/3-----------> 32*pi in³
if one cup---------------------> 32*pi in³
X---------------------------> (2000/3)*pi in³
X=(2000/3)*pi/(32*pi)------------> 20.83----------> 21 cups
the answer part b) is 21 cups
(c) One cylindrical cup has a diameter of 4 in. and a height of 6 in. How many cups of water must he scoop out of the sink with this cup to empty it?
volume of a cylindrical cup=pi*r²*h
diameter=4 in--------------> r=2 in
h=6 in
volume of a cylindrical cup=pi*2²*6-----------> 24*pi in³
if one cup---------------------> 24*pi in³
X---------------------------> (2000/3)*pi in³
X=(2000/3)*pi/(24*pi)------------> 27.77----------> 28 cups
the answer part c) is 28 cups
a) The volume of a sphere is (4/3)pi(r^3). If you input a 10 for the radius of sink, you will get 4000/3(pi). However, we have to divide it by 2 since it is a half-sphere. So the volume is 2000/3(pi).
For each cone, the volume formula is: pi(r^2)h/3.
b) With a radius of 4 and a height of 6, the volume is 100.53. Dividing the volume of the sink by this takes 21 scoops.
c) With a radius of 2 and a height of 6, the volume is 100.53. Dividing the volume of the sink by this takes 84 scoops.

Given , A right angled triangle with an interior angle measuring 35 and a side measuring 20.
To calculate the value of x, we use the trigonometric ratio.
We have been given the measurement of hypotenuse and have to find the measurement of the opposite side of angle 35. Here we use sine ratio to find the measurement of opposite side.
[tex] sin (\theta) = \frac{opposite}{hypotenuse} [/tex]
measurement of hypotenuse = 20 and [tex] \theta [/tex] = 35,
[tex] sin(35)=\frac{x}{20}\\\\x=20 \times sin(35)\\\\ value\: of \:sin (35) = 0.57\\\\x= 20 \times 0.57 = 11.48 \approx 11.5 [/tex]
Hence , value of x = 11.5

Tomas works as an underwater photographer. He starts at a position that is 19 feet below sea level. He rises 9 feet, then descends 16 feet to take a photo of a coral reef. Enter an expression to find his position relative to sea level when he took the photo and then evaluate the expression.
Answers
Expression:
X = Xo + 9 feet - 16 feet
X = - 19 feet + 9 feet - 16 feet
X = - 26 feet (26 feet below the sea level)
Explanation:
1) Call Xo the initial position, and X the variable to indicate the actual position
2) Use position 0 for sea level
3) use negative sign for positions under the sea level
4) use positive sign for positions above the sea level
5) Expression:
Final position = initial position + movements upward - movements downward
X = Xo + 9 feet - 16 feet
X = - 19 + 9 feet - 16 feet = - 26 feet

According to the Bohr model, the radius of a hydrogen atom is approximately 5.29 × 10/-11 meters. What is this measurement written in standard form?

B. 0.00000000000529 meters
C. 0.0000000000529 meters
D. 0.000000000529 meters
Answers
The measurement 5.29 × 10⁻¹¹ meters written in the standard form is option C, 0.0000000000529 meters.
Given that:
According to the Bohr model, the radius of a hydrogen atom is approximately 5.29 × 10⁻¹¹ meters.
It is required to write this number in scientific notation in the standard form.
Here the power of the 10 is negative.
So, the decimal point has to be shifted to the left.
Now, since the number to the power is 11, the decimal points have to be shifted 11 points to the left.
After shifting 1 point, the number is 0.529 × 10⁻¹⁰.
After shifting two points, the number is 0.0529 × 10⁻⁹.
In this way,
The number will have 10 zeroes before 5.
Hence the number is 0.0000000000529 meters, which is option C.

Hit enter until the second value equals 8. You get {7969.24037265,8}.

For the second part, use {Ans(1)x1.2, Ans(2)+1}. The first part increases the number of miles and the second goes to the next week. Hit enter until the second value is 10. The result is {6.1917364224,10}. The question says to round to the nearest mile, which is 6 miles.

Morty buys and sells computer parts he bought two monitors for $25 each and later sold them for 88 each he bought four cases for $15 each and later sold them for $24 each if you buy five memory modules for $20 each and later sold them for $55 each
Answers
Morty earns a total profit of $337 from buying and selling monitors, cases, and memory modules by calculating the individual profits for each transaction and summing them up.
Explanation:The question is asking for a calculation of the profit Morty makes on buying and selling computer parts. There are three transactions to consider:
Morty buys two monitors for $25 each and sells them for $88 each.He buys four cases for $15 each and sells them for $24 each.He buys five memory modules for $20 each and sells them for $55 each.To find the total profit, we calculate the profit for each transaction:
Profit from monitors: (2 * $88) - (2 * $25) = $176 - $50 = $126Profit from cases: (4 * $24) - (4 * $15) = $96 - $60 = $36Profit from memory modules: (5 * $55) - (5 * $20) = $275 - $100 = $175Then we sum these individual profits for the total profit:
Total profit = $126 + $36 + $175 = $337
The total profit that Morty makes from buying and selling these computer parts is $337.
Morty made a profit of $126 on the monitors, $36 on the cases, and $175 on the memory modules.
Explanation:Morty bought two monitors for $25 each, costing him a total of $50. He later sold them for $88 each, earning a total of $176. He bought four cases for $15 each, costing him a total of $60. He later sold them for $24 each, earning a total of $96.
He also bought five memory modules for $20 each, costing him a total of $100. He later sold them for $55 each, earning a total of $275.
In summary, Morty made a profit of $126 on the monitors, a profit of $36 on the cases, and a profit of $175 on the memory modules.
Which set of statistics best describes a typical home value in Maya's neighborhood and how the values vary?
Answers
Answer:
The typical home value is best described by the median.
The value variation is best described by IQR.
Step-by-step explanation:
For samples of data that have outliers, the set of statics that best describes central tendencies are the robust measures.
The median is a robust measure because the outliers will have very little impact on the result of the measure.
The IQR is a robust measure because it takes the difference between the 75th percentile and the 25th percentile of a sample, so the outliers are ignored.

Olivia ate 1/4 of a pizza if there were 12 slices of pizza how many slices did Olivia eat
Answers
There are many ways you can solve this question. I'll show you a few. Way 1:
Convert 1/4 to a decimal by dividing its numerator by its denominator.
1 ÷ 4 = 0.25
1/4 is 0.25 as a decimal.
Then, multiply the amount of slices of pizza by the decimal form.
12 × 0.25 = 3
Way 2:
Since the numerator is 1, simply divide ths number of slices by the denominator of the fraction. You will get the same answer.
12 ÷ 4 = 3
ANSWER:
Olivia ate 3 slices of pizza.
1.8y-9.3y-6.3y hope you can help
Answers
First subtract 1.8y from 9.3y which is 7.5y, but since you are actually subtracting a larger number from a smaller number, you add a negative sign because your answer is less than 1. Then you add -6.3y to to -7.5y because you have two negatives. While it may seem like you should add them, you will subtract because you are adding essentially more negative to the negative number. I hope that makes sense! Once you add -6.3y to -7.5y your answer is -13.8y.
