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.

2. At the grocery store checkout, you watch at the register as it rings up your purchases and coupons. The prices are as follows:
$2.95
$1.19
$4.61
$1.74
$3.04
$8.83
$1.16
− $0.75 (coupon)
− $1.00 (coupon)
The register gives your total bill as $21.77.
(a) Round each price and coupon to the nearest dollar and then estimate the total amount of the bill.
(b) Using your estimate, determine whether the total on the register is reasonable. Justify your answer.
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 :
(a) Round each price and coupon to the nearest dollar and then estimate the total amount of the bill.
The prices are as follows:
$2.95 estimated to $3 as (9>5)
$1.19 estimated to $1 as (1<5)
$4.61 estimated to $5 as (6>5)
$1.74 estimated to $2 as (7>5)
$3.04 estimated to $3 as (0<5)
$8.83 estimated to $9 as (8>5)
$1.16 estimated to $1 as (1<5)
− $0.75 (coupon) estimated to -$1 as (7>5)
− $1.00 (coupon) estimated to -$1 as (0<5)
The total amount bill is $3+$1+$5+$2+$3+$9+$1-$1-$1=$22.
So, Estimated total amount of the bill is $22.
(b) Using your estimate, determine whether the total on the register is reasonable. Justify your answer.
The register gives your total bill as $21.77.
The total on the register is reasonable because even with the rounded price at the end the price became same which is reasonable.
As 21.77 estimated to 22 as (7>5).
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?
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]
The relationship between the two variables, x, and y, represent a direct variation
therefore
the answer is
[tex]y=2x[/tex] or [tex]x=y/2[/tex]
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?
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

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
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?
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.

0.12 or 1.2% which is greater
1.2% is the greater percentage than 0.12
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.

0.12 isn’t a full percent, the decimal determines the greatness of the two number.
1.2% is the larger number.
1.2% = 1.2/100
= 0.012
Therefore, 1.2% is the greater percentage than 0.12

According to the school survey, 12% of the students at Rockwood Junior High School speak Spanish. There are 36 students at the school who speak Spanish. How many students were surveyed?
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]
Thus, 300 students were surveyed.
