Violet is watching the sand in a hourglass drain from the upper portion to the lower portion of the glass. She wonders how fast the sand is draining.

Which unit rates would be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass?

Select EACH correct answer.



gallons per hour

liters per hour

cubic centimeters per minute

cubic inches per second

Answers

Answer 1
Gallons and litters are liquid. Cubic inches per second would be to fast i think so Cubic Centimeters by minute?
Answer 2

The unit rates which will be reasonable for Violet to use to describe how fast the sand is draining from the upper portion to the lower portion of the glass is cubic centimeters per minute.

Explanation:

As the first 2 options gallons per hour and liters per hour, these denote liquid forms. But sand is not liquid that is why it cannot be the answer.

Cubic inches per second is very fast as compared to the small hourglass and the amount of sand that could be present in it. Moreover one side of the hourglass needs to be emptied in 24 hours, so this option is also not possible.

How to subtract 4/5 and 3/10 in simplest form

Answers

First you must find a common denominator. In this case 10 will work. You then multiply the top number by whatever you multiplied the bottom number by. This is shown below:
4/5- 3/10 = 8/10- 3/10 
You can now solve this to get 5/10. This answer can then be reduced to 1/2. 
1- find a common denominator of 5 and 10. Their least common denominator is 10 so convert 4/5 to a fraction with a denominator of 10 ( 8/10). Now subtract 3/10 from 8/10 to get 5/10.

Carlos purchased an antique chair for $15 he later so this year for $27 to an antique dealer what was the percent markup of the chair

Answers

Okay. So, to find the percent change, we have to do change/original. In this case, it would be 12/15, because 15 and 27 are apart by 12. 12/15 is 0.8. Multiply that by 100 and you get 80. There was an 80% markup of the chair sold to the antique dealer.

Answer:  The required percent markup is 80%.

Step-by-step explanation:  Given that Carlos purchased an antique chair for $15 and later he sold it this year for $27 to an antique dealer.

We are to find the percent markup of the chair.

The markup price of the chair is given by

[tex]m_p=\$(27-15)=\$12.[/tex]

Since Carlos purchased the chair for $15, so the markup percent is given by

[tex]\dfrac{m_p}{15}\times100\%\\\\\\=\dfrac{12}{15}\times100\%\\\\\\=\dfrac{4}{5}\times100\%\\\\=80\%.[/tex]

Thus, the required percent markup is 80%.

After m months, the height of a plant is 10+3m millimeters. How tall is the plant after 8 months? 3 years?

Answers

for 8 months it will be 34 mm. for 3 years it should be 118 mm

After 8 months, the plant is 34 millimeters tall, and after 3 years (36 months), it's 118 millimeters tall.

To find the height of the plant after 8 months and 3 years, let's first understand the pattern. The height is given by the equation ( 10 + 3m ), where ( m ) represents the number of months.

Height after 8 months:

Substituting ( m = 8 ) into the equation:

[tex]\( \text{Height} = 10 + 3(8) \)[/tex]

[tex]\( \text{Height} = 10 + 24 \)[/tex]

[tex]\( \text{Height} = 34 \)[/tex] millimeters.

Height after 3 years (36 months):

Substituting ( m = 36 ) into the equation:

[tex]\( \text{Height} = 10 + 3(36) \)[/tex]

[tex]\( \text{Height} = 10 + 108 \)[/tex]

[tex]\( \text{Height} = 118 \)[/tex] millimeters.

So, after 8 months, the plant is 34 millimeters tall, and after 3 years (36 months), it's 118 millimeters tall.

300 students were surveyed.
That's the way I answer in my country but I'm not sure about this solution is correct in your school or not.

Answer:

300 students were surveyed.

Step-by-step explanation:

We are given the following information in the question:

Percentage of students at Rockwood Junior High School who speak Spanish = 12%

Number of students at Rockwood Junior High School who speak Spanish = 36

We have to find the total number of students who surveyed:

Formula:

Let x be the total number of students who were surveyed.

[tex]12\% \text{ of }x = 36\\\\\displaystyle\frac{12}{100}\times x = 36\\\\x = \frac{36\times 100}{12}\\\\x = 300[/tex]

B) The total on the register is reasonable because even with the rounded price at the end, it is only 23 cents off, which is good.

Answer and explanation:

Given : At the grocery store checkout, you watch at the register as it rings up your purchases and coupons.

The register gives your total bill as $21.77.

To find :

An arithmetic sequence is one where you add (or subtract) a certain number to change the value. For the first sequence, it's clear that we subtract 4 every time, so that is arithmetic. Next, we constantly go from positive to negative, so we can be sure that we don't add the same number every time. For the third one, (-5.0-(-8.6))=3.6, and for -1.4-3.6 we get -5, showing that we add 3.6 for every value and the sequence is therefore arithmetic. For the fourth one,
(-3.1-(-6.2))=3.1, but -1.55-3.1 is not 3.1, showing that that is not arithmetic. For the last one, 3-(-3)=6, 9-3=6, etc. proving that you add 6 every time and the sequence is therefore arithmetic.

A movie theater has 24 screens. The ratio of action films to other film is 1:2 in the summer. How many action films are shown?

Answers

12:12 would be an even ratio of 1:1 but since you have a ratio of 1:2 you would take away half of the action movies and add it to the other category so the ratio would be 6:18 (1:2 if reduced) meaning 6 action films would be shown.

Answer:

8 action films being shown

Step-by-step explanation:

Great question, it is always good to ask away and get rid of any doubts that you may be having.

Based on this question we can see that the movie theater has 1 action movie for every 2 other type of movies. We can add these two numbers together and divide by 24 to find out how many action movies are playing compared to the other types of movies.

[tex]1 + 2 = 3[/tex]

[tex]24 / 3 = 8[/tex]

8 action movies : 16 other type of movies

As we can see from the adjusted ratio above, there are 8 action films being shown

If y=-7 when x=-21, what is the value of x when y=9

Answers

y=-7=x+14 if x - -21

So then when y=9, 9=x-21.
Solve for x.
x=9+21
x=30
You'd be well advised to identify the type of problem you're working with.  Is this problem one of direct proportion (as I think it is)?  If so, say so.

If y = -7 when x = -21, then y  = (1/3)x, and (1/3) is the constant of proportion.

A similar truth is that x = 3(y), as -21 = 3(-7)

So, if y=9, x = 3(9) = 27

Peaches are being sold for $2 per pound. If x represents the number of pounds of peaches bought and yrepresents the total cost of the peaches, which best describes the values of x and y?

2) y = total cost of the peaches
3) formula would be: y = $2x

Let

x----------> represents the number of pounds of peaches bought

y----------> represents the total cost of the peaches

we know that

Peaches are being sold for [tex]2\frac{\$}{pound}[/tex]

so

the equation that best describes the values of x and y is equal to

[tex]y=2x[/tex] or [tex]x=y/2[/tex]

what is the preimter and area of a rectangle that is 30 inchs long and 39 inchs wide

Answers

Multiple both numbers by 2 since there are 2 of them on a rectangle. After, add them.

30 x 2 = 60
39 x 2 = 78
60 + 78 = 138

And never forget to label your units!

The perimeter of the rectangle is 138 inches.

To get the area, multiply the sides by each other.

30 x 39 = 1170

The area of the rectangle is 1170 inches^2, or 1170 inches squared.
Perimeter is 138 (60*2+39*2)

Area is 1170 (30*39)
