Step-by-step explanation:
Volume of cylinder = pi r^2 h
Volume of square container = s x s x h
they need to be equal
pi r^2 h = s^2 h
pi (2)^2 * 10 = 4^2 h (diameter = 4 then radius = 2)
40pi / 16 = h = 7.9 in = ~ 8 in to the nearest 1/4 inch
Miguel is typing up the final copy of his essay for class. He can type about 20 words per minute. He has typed 1,265 words so far, and his final essay is 4,254 words in length.
How can Miguel determine the number of minutes it will take for him to finish typing the rest of his essay?
Match each step of the arithmetic solution with the correct description.
Answer:
Step 1: Subtract 1265 from 4254 to get the number if words he still needs to type; 2,989
Step 2: Divide 2,989 words by 20 words/minute; 149.45 minutes.

Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.
1÷4 x³ = –27÷4
1. First, divide both sides of the equation by 4.
1÷4 x³/4 = –27/4/4
2. Next, on the left side of the equation, use inverse operations to get rid of the division. This will give us x³ = –27.
3. Then, to solve for x, take the cube root of both sides of the equation.
Cube root of x³ = cube root of –27
4. To check your answer, plug in -3 for x in the original equation and solve.
1÷4 x³ = –27/4
1÷4 (-3)³ = –27/4
1÷4 (-27) = –27/4
1 = 1
Since 1 = 1, the answer checks out.
Therefore, the solution to the equation is x = -3.

5 units up
1 unit down

The translation used to create the image include the following: A. 5 units down.
What is a translation?In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;
g(x) = f(x + N)
Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.
Based on the information provided, we have:
(x, y) → (x + h, y + k)
(1, -1) → (1, -6).
1 + h = 1
h = 1 - 1
h = 0
-1 + k = -6
k = -6 + 1
k = -5.

Answer:
266
Step-by-step explanation:
Therefore, the answer to what divided by 7 equals 38 is 266. You can prove this by taking 266 and dividing it by 7, and you will see that the answer is 38. Tip: For future reference, when you are presented with a problem like "What divided by 7 equals 38?", all you have to do is multiply the two known numbers together.

Marvin was in charge of ordering sodas for the class fundraiser. He made a circle graph to show the number of each size of soda. However, he accidently put his work in the graph showing the degree measures he used to make the chart instead of the number of sodas he needed and he threw away his original paper showing the number of each. Help him figure out how many of each size of soda he needs to order by answering the questions below. (Hint: There are 360 degrees total in a full circle.)

Rita′s work day for Monday is described in the list. worked from 8:00 a.m. to 12:00 p.m. took a 30-minute lunch break worked until 6:00 p.m. Rita does not get paid for her lunch break. How much money did Rita earn for the time she worked on Monday? Show or explain all of the steps you used to determine your answer.]
Answer: $158
Step-by-step explanation:
$16(8) + $24(1 ¼) = $128 + $30 = $158
Rita earned a Total of $196 for the time she worked on Monday.
To determine how much money Rita earned for the time she worked on Monday, we need to calculate her earnings for each portion of the day separately.
1. From 8:00 a.m. to 12:00 p.m. (4 hours):
Rita worked for 4 hours within the first 8 hours, so she earns her regular rate of $16 per hour for this time:
Earnings = 4 hours * $16/hour = $64.
2. From 12:30 p.m. to 6:00 p.m. (5.5 hours):
Rita worked for 5.5 hours beyond the initial 8 hours, so she earns 1.5 times her regular rate for each of these hours:
Earnings = 5.5 hours * ($16/hour * 1.5) = $132.
Now, we can sum up Rita's earnings for both periods:
Total earnings = Earnings from the first period + Earnings from the second period
Total earnings = $64 + $132
Total earnings = $196.
Therefore, Rita earned a total of $196 for the time she worked on Monday.

A certain type of cereal costs $3.79 for 19.5 ounces.
What is the unit rate?
Enter your answer, rounded to the nearest cent, in the box.
$__per oz.
Answer:
To find the unit rate, we divide the total cost by the total number of ounces:
Unit rate = total cost ÷ total number of ounces
Unit rate = $3.79 ÷ 19.5 ounces
Unit rate = $0.194 per oz.
Rounding to the nearest cent, the unit rate is $0.19 per oz.

The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.

He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.
as the graph can not be used:
Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.
However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.

A chemist is weakening an 80% solution by adding a 40% solution. How much of each should he use to get 100 milliliters of a 50% solution? the chemist’s problem is modeled by the system: {0.80x+0.40y=0.50⋅100 (x+y=100 where x is the number of milliliters of 80% solution and y is the number of milliliters of 40% solution.
Answer: The chemist needs to mix 25 milliliters of the 80% solution with 75 milliliters of the 40% solution to get 100 milliliters of a 50% solution.
Step-by-step explanation:
Let x be the number of milliliters of 80% solution needed, and y be the number of milliliters of 40% solution needed.
From the first equation, we can write:
0.80x + 0.40y = 0.50(100)
Simplifying this equation, we get:
0.80x + 0.40y = 50
Dividing both sides by 0.20, we get:
4x + 2y = 250
From the second equation, we know that:
x + y = 100
Solving this equation for y, we get:
y = 100 - x
Substituting this expression for y into the first equation, we get:
4x + 2(100 - x) = 250
Simplifying this equation, we get:
2x + 200 = 250
Subtracting 200 from both sides, we get:
2x = 50
Dividing both sides by 2, we get:
x = 25
Substituting this value for x into the equation y = 100 - x, we get:
y = 75
Therefore, the chemist needs to mix 25 milliliters of the 80% solution with 75 milliliters of the 40% solution to get 100 milliliters of a 50% solution.
