Unit rate is the quantity of an amount of something at a rate of one of another quantity.
If out of 28 students, 12 students packed their lunch.
The number of students who packed their lunch out of 336 students is 144 students.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
Example:
3 miles in 3 hours.
1 mile in one hour.
We have,
In a class of 28 students, 12 students packed their lunch.
We can write this as:
28 students = 12 students packed lunch ______(1)
We have to make 28 students into 336 students.
This can be done by multiplying 12 on both sides of the equation (1)
Multiply 12 on both sides.
12 x 28 students = 12 x 12 students packed lunch
336 students = 144 students packed lunch
Thus,
The number of students who packed their lunch out of 336 students is 144 students.

To compute the square of the length of a sloped side, you need to sum the squares of the rise and the run. For example, the square of the length of 'a' in triangle F is ...
a² = rise² + run² = 1² +2² = 1 +4 = 5
__
Additional comment
When computing the slopes of the various triangle sides, you need to pay attention to the sign of the "rise" for a positive "run."
For the distance purpose here, the rise and run are squared, so their signs are irrelevant. You can treat them all as positive numbers.

turn 5/11 into a decimal: 0.45 which is LESS than 0.50 (0.5).
Answer:
<
Step-by-step explanation:
When comparing fractions and decimals/fractions and percentages/decimals and percentages, it's always good to convert them to have the same type on either side. However, you don't really need to with this problem.
Here's a trick: the larger the denominator is in a fraction, the smaller the value of the fraction is. If the fraction on the left were 5/10, then we know that it would be equal to 0.5 (you can convert either one). Now, since the denominator of the fraction is one greater than 10, we know that the fraction's value is just a little bit less than 5/10. This makes the fraction less than 0.5.
I hope it made sense. Brainliest would be cool but no worries.

What is the surface area of a right circular cylindrical oil can, if the radius of its base is 4 inches and its height is 11 inches? for 25 points
Step-by-step explanation:
Given
Radius (r) = 4 inches
height (h) = 11 inches
Total surface area of cylindrical oil can is
= 2πr ( r + h)
= 2 * 22 / 7 * 4 ( 4 + 11)
= 2 * 22/7 * 4 * 15
= 377.14 inches ²
If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.
What is the surface area of a right circular cylindrical figure?Let b and h be the radius of the base and height of a right circular cylindrical figure respectively. Then the surface area of this right circular cylindrical figure is 2πb(b + h).
How to solve this problem?Given that the radius of the base of the can is 4 inches.
The height of the can is 11 inches.
Then the surface area of the can = 2π * 4(4 + 11) = 8π(15) = 120π = 376.99 square inches
Therefore, If the radius of a right circular cylindrical oil can base is 4 inches and its height is 11 inches, then the surface area of that right circular cylindrical oil can is 376.99 square inches.

Answer:
(1) The angles are 81⁰, 76⁰, 23⁰ and y = 157⁰
(2) The angles are E = 122⁰, P = 40⁰, and Q = 18⁰
Step-by-step explanation:
(1)
Considering the first diagram;
(4x + 29) + (5x + 11) + (2x - 3) = 180 (sum of angles in a triangle)
collect like terms together;
(4x + 5x + 2x) + ( 29 + 11 - 3) = 180
11x + 37 = 180
11x = 180 - 37
11x = 143
x = 143 / 11
x = 13
The angles of this triangle are calculated as follows;
4x + 29 = (4 x 13) + 29 = 81⁰
5x + 11 = (5 x 13) + 11 = 76⁰
2x - 3 = ( 2 x 13) - 3 = 23⁰
y⁰ + (2x - 3) = 180 (sum of angles on a straight line)
y⁰ + 23⁰ = 180
y⁰ = 180 - 23
y = 157⁰
(2)
Considering the second triangle;
(15m + 17) + (7m - 9) + (4m - 10) = 180 (sum of angles in a triangle)
(15m + 7m + 4m) + (17 - 9 - 10) = 180
26m - 2 = 180
26m = 180 + 2
26m = 182
m = 182 / 26
m = 7
The angles of this second triangle are calculated as follows;
E: 15m + 17 = (15 x 7) + 17 = 122⁰
P: 7m - 9 = (7 x 7) - 9 = 40⁰
Q: 4m - 10 = ( 4 x 7) - 10 = 18⁰

Which expression has a greater value, 3/8 x 5:6 or 3/8 divided by 5/6? Explain
Answer:
3/8 divided by 5/6
Step-by-step explanation:
To divide a fraction by a fraction, you multiply the first fraction by the reciprocal (aka the fraction flipped upside down, in this case the reciprocal of 5/6 is 6/5). Since 6/5 is greater than 5/6, 3/8 divided by 5/6 is greater than 3/8 times 5/6.
Answer:
[tex]\frac{3}{8}[/tex] ÷ [tex]\frac{5}{6}[/tex]

Answer:
Lara should buy 8 boxes

To start we would need to do
72/10
since 72 isn't a multiple of ten we can round it down to 70, then do
70/10=7
since we still have two teeth, we can put them in their own box so
7+1=8
