Using proportions, the amounts needed of brown and green material for 52 gallons of compost are given as follows:
Brown material: 39 gallons.
Green material: 13 gallons.
What is a proportion?A proportion is a fraction of a total amount, and in problems involving it, basic arithmetic operations such as multiplication or division are used along with the unit rates to find the equivalent measures.
On the first column of the table, the total amount is:
12.75 + 4.25 = 17 gallons.
The fractions of each material are given as follows:
Brown material: 12.75/17 = 0.75
Green material: 4.25/17 = 0.22.
Hence the amount of brown material needed with 52 gallons is:
0.75 x 52 = 39 gallons.
The amount of green material needed with 52 gallons is:
0.25 x 52 = 13 gallons.

new tires for $319.96
$
319.96
.
What is the unit price of the tires?
Answer:
79.99
Step-by-step explanation:
You divided 319.96 by 4 which gives you 79.99
Answer:
$ 79.99
Step-by-step explanation:
4 tires = $319.96
1 tire =$b
cross multiplying,
4× b = 1 × 319.96
→ 4b = 319.96
→ b = 319.96 ÷ 4

what is the length of each side of a regular hexagon?
Answer: s = P ÷ 6
Step-by-step explanation:
The simplest, and by far most common, way of finding the length of a regular hexagon's sides is using the following formula: s = P ÷ 6, where P is the perimeter of the hexagon, and s is the length of any one of its sides.
Answer:
All the interior angles measure 120°. All the exterior angles measure 60°. Since all angles are equal in a regular hexagon, each angle is 120o and the sum of all the interior angles is 720o.
Step-by-step explanation:
The simplest, and by far most common, way of finding the length of a regular hexagon's sides is using the following formula: s = P ÷ 6, where P is the perimeter of the hexagon, and s is the length of any one of its sides

List the sample space for rolling a fair six-sided die. S = {1} S = {6} S = {1, 2, 3, 4, 5, 6} S = {1, 2, 3, 4, 5, 6, 7, 8}
Answer:
The sample space for rolling a fair six-sided die is: S = {1, 2, 3, 4, 5, 6}
The sample space represents all the possible outcomes of an event. In this case, the event is rolling a fair six-sided die, so the sample space is the set of all the possible numbers that can appear on the die, which are 1, 2, 3, 4, 5 and 6.
Option A, S = {1}, is incorrect because this only represents one outcome, not all possible outcomes.
Option B, S = {6}, is incorrect because this only represents one outcome, not all possible outcomes.
Option C, S = {1, 2, 3, 4, 5, 6}, is correct as it represents all possible outcomes.
Option D, S = {1, 2, 3, 4, 5, 6, 7, 8}, is incorrect because this includes numbers that cannot appear on a six-sided die, and it does not represent all possible outcomes.

The heights, in feet, of the trees for sale at two nurseries are shown below.
Yard Works: 7, 9, 7, 12, 5
The Grow Station: 9, 11, 6, 12, 7
Which statements are true regarding the measures of center and variability of these data sets? Select three choices.
A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
B. The median of the tree heights at Yard Works is greater than the median of the tree heights at The Grow Station.
C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
D. The mean absolute deviation of the tree heights at Yard Works is greater than the mean absolute deviation of the tree heights at The Grow Station.
E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
The statements that are true regarding the measures of center and variability of these data sets include:
A. The mean of the tree heights at Yard Works is less than the mean of the tree heights at The Grow Station.
C. The range of the tree heights at Yard Works is greater than the range of the tree heights at The Grow Station.
E. The mean absolute deviation of the tree heights at Yard Works is equal to the mean absolute deviation of the tree heights at The Grow Station.
How to calculate the mean of any data set?In Mathematics and Statistics, the mean for any set of data can be calculated by using the following formula:
Mean, \bar{x} = ∑x/n
Where:
∑x represents the sum of all data values.n represents the total number of data items.Based on the information provided, we have:
Mean of Yard Works = (7+9+7+12+5)/5
Mean of Yard Works = 8.
Mean of Grow Station = (9+11+6+12+7)/5
Mean of Grow Station = 9.
Range is the difference between the maximum and minimum numbers;
Range of Yard Works = 12 - 5
Range of Yard Works = 7.
Range of Grow Station = 12 - 6
Range of Grow Station = 6.
Mean absolute deviation is given by;
MAD = 1/n ∑|x - μ|
Where:
n represents the number of data (observed values)μ represents the mean of the data set.x represents the individual data (values)Mean absolute deviation of Yard Works = 2
Mean absolute deviation of Grow Station = 2.

Answer:
3/8
Step-by-step explanation:
So 1 pizza was already eat right and 1/8 was eating I'm assuming it 1/8 then 1/2 is 4/8 so add that witch is 5/8 so 5/8 - 8/8= 3/8
Answer:
There were 3/8s left
Step-by-step explanation:
1 1/8 + 1/2 = 1 5/8

The area of a circle is 153.86 square meters. What is the diameter of the circle? Use 3.14 for π.
Answer:
Step-by-step explanation:
A = πr^2
(153.86) = (3.14) r^2
Divide 3.14 on both sides.
49 = r^2
Square root both sides.
7 = r
D = 2r
D = 2(7)
D = 14
The diameter of the circle is 14 square meters.
Answer:
14 meters²
Step-by-step explanation:
Since the formula to find the diameter is d = 2r, we need to first find the radius, which can be r = square root of Aπ over π if we take the formula for the area of a circle and isolate the radius. After simplifying r = square root of 153.86π over π to 7 and multiplying that by 2, we get the circle's diameter of 14 meters. Hope this helps!

Only numbers greater than 5 satisfy the inequality.
The answer is a set that only contains numbers greater than 5.
Answer: {6, 8, 10}
The values that satisfies the condition n+5>10 among {2,4,6,8,10} is
{6,8,10}
let check the every value of {2,4,6,8,10} satisfies the condition n+5>10
let n=2
= n+5 = 2+5 = 7
7!>10
so 2 does not satisfies the condition
let n=4
= 4+5 = 9
9!>10
lly 4 does not satisfies the condition
let n= 6
=n+5 = 6+5 = 11
11>10 satisfies the condition
let n= 8
=n+5 = 8+5 = 13
13>10 satisfies the condition
let n= 10
=n+5 = 10+5 = 15
15>10 satisfies the condition
only {6,8,10} satisfies the given condition

What's the value of x?
Answer:
x = 62
Step-by-step explanation:
Recall the properties of parallel lines with transversals. Vertical angles are congruent so the angle across from 118° is also 118°.
Recall the consecutive interior angles theorem. If two angles are on the same side of the transversal and are between the two parallel lines, then their measures add up to 180°. 180° - 118° = 62°.
Therefore, x = 62.
