Answer:
0.375mL/polyethylene
Step-by-step explanation:
Total number of plastic bags = 24 plastic bags
amount of polyethylene created = 9mL
This means that;
24 plastic bags = 9mL of polyethylene
1 plastic bags = x
Cross multiply
24 * x = 9 * 1
24x = 9
x = 9/24
x = 0.375mL/polyethylene
Hence the rate of polyethylene used per plastic bag is 0.375mL/polyethylene

There are 272 people in an audience. The ratio of adults to children is 5 : 3. How many are children? (please answer)
Answer:
There are 102 children
Step-by-step explanation:
Let us solve the question
∵ There are 272 people in an audience
∴ The total number of people = 272
∵ The ratio of adults to children is 5: 3
→ Find the sum of the two parts of the ratio
∴ The sum of the parts of the ratio = 5 + 3 = 8
→ By using the ratio method
→ Adults: Children: People
→ 5 : 3 : 8
→ A : C : 272
→ By using the cross multiplication
∵ C × 8 = 3 × 272
∴ 8C = 816
→ Divide both sides by 8
∴ C = 102
∵ C represents the number of children
∴ There are 102 children
Consider 4x +12 < 28. which value of x makes the given inquality TRUE? A) 3 B) 6 C) 7 D) 10
Answer:
A
Step-by-step explanation:
4(3)+12=24, which is less than 28, so the inequality would be true
Answer:
The answer is A)3
Step-by-step explanation:
4 multiplied by 3 is 12, 12+12 is 24, less than 28
2 multiplied by 6 is 24+12 is 36, greater than 28
4 multiplied by 7 is 28, already over 28
4 multiplied by 10 is 40 is already way over 28

The height of an isosceles triangle is 12cm. The base of the triangle is 18cm. Work out the length of the equal sides
Answer:
The length of the equal sides is 15 centimeters.
Step-by-step explanation:
Since, base and height of the triangle are perpendicular to each other. In an isosceles triangle, the value of each equal length ([tex]l[/tex]), measured in centimeters, can be determined by the following Pythagorean identity:
[tex]l = \sqrt{\frac{b^{2}}{4}+h^{2}}[/tex] (1)
Where:
[tex]b[/tex] - Base of the triangle, measured in centimeters.
[tex]h[/tex] - Height of the triangle, measured in centimeters.
If we know that [tex]b = 18\,cm[/tex] and [tex]h = 12\,cm[/tex], then the value of each equal length within the isosceles triangle is:
[tex]l =\sqrt{\frac{(18\,cm)^{2}}{4}+(12\,cm)^{2}}[/tex]
[tex]l = 15\,cm[/tex]
The length of the equal sides is 15 centimeters.
The number of cartons of apples sold at a store each day for eight days is shown. 30 , 40 , 51 , 30 , 34 , 20, 30, 45 Determine the value for each statistical measure. 2. The number of fifth graders buying lunch each day for nine days is shown. 90 , 72 , 48 , 84 , 77 , 72, 50, 83 Determine the value for each statistical measure. Mean Median Mode Range 30 31 35 32
Answer:
Mean = 35
Median = 0.5(n + 1)th term
Median = 0.5(9) = 4.5th term
(30 + 34) /2 = 32
Mode = 30 ( most frequent)
Range = (51 - 20) = 31
Mean = 72
Median = 0.5(n + 1)th term
Median = 0.5(9) = 4.5th term
4th + 5term = (72 + 77) /2 = 74.5
Mode = 72 ( most frequent)
Range = (90 - 48) = 42
Step-by-step explanation:
Given :
1.)
Data: 30 , 40 , 51 , 30 , 34 , 20, 30, 45
Rearranged data : 20, 30, 30, 30, 34, 40, 45, 51
Mean = ΣX / n = 280 / 8
Mean = 35
Median = 0.5(n + 1)th term
Median = 0.5(9) = 4.5th term
(30 + 34) /2 = 32
Mode = 30 ( most frequent)
Range = (51 - 20) = 31
2.)
90 , 72 , 48 , 84 , 77 , 72, 50, 83
Rearranged data : 48, 50, 72, 72, 77, 83, 84, 90
Mean (m) = ΣX / n = 576 / 8
Mean = 72
Median = 0.5(n + 1)th term
Median = 0.5(9) = 4.5th term
4th + 5term = (72 + 77) /2 = 74.5
Mode = 72 ( most frequent)
Range = (90 - 48) = 42
35% of the students at charles drew middle school are 6th graders if there are 84 sixth graders what is the total number of student in the school
Answer: The total number of student in the school = 240.
Step-by-step explanation:
Let x be the total number of students in the school.
Given: 35% of the students at Charles drew middle school are 6th graders.
i.e. Number of sixth graders = 35% of x = 0.35x [35% = 0.35]
Since there are 84 sixth graders in the school,
So [tex]0.35x=84[/tex]
Divide both sides by 0.35, we get
[tex]x=\dfrac{84}{0.35}=\dfrac{84\times100}{35}=240[/tex]
Hence, the total number of student in the school = 240.

A box of an area covers four feet if the height of the box if 3 feet what is the volume of the box?
Answer:
12 cubic ft.
Step-by-step explanation:
A=bh=4(3)=12 ft^3
Answer:
12 ft ^3
Step-by-step explanation:
Volume of the box would be width x length x height
If the box of an area already covers four feet (width times length) we just need to multiply by the height:
4*3 =12 cubic feet

In a recent year, 23.9% of all registered doctors were female. If there were 47,400 female registered doctors that year, what was the total number of registered doctors?
Round your answer to the nearest whole number.
Answer:
23.9% = 47400
divide both sides by 23.9 to find 1%
1% = 1983.26359
now multiply by 100 to find total number of doctors
1983.26359 X 100
100% = 198326

Two angles are complementary. Angle 1 has a measure of
3x + 14 and Angle 2 has a measure of 4x + 6. What is the
value of x?
Answer:
x = 10
Step-by-step explanation:
3x + 14 + 4x + 6 = 90
7x + 20 = 90
90 - 20 = 70
70 / 7 = 10
x = 10

Find the perimeter and area of the polygon shown below.
O P = 76 feet, A = 338 square feet
OP= 58 feet, A = 338 square feet
OP = 91 feet, A = 390 square feet
O P = 76 feet, A = 330 square feet
p = 76 a = 330 so your answer is D
The perimeter of the polygon is 76ft and Area is 338 sq.ft, the correct option is A.
What is a Polygon?A polygon is a closed structure with 3 or more than 3 sides.
The given polygon has 4 sides, so it is a quadrilateral
To find the area of the polygon, it can be divided into a rectangle and a triangle as shown
Area of Rectangle = Length * Width
Area of Triangle = (1/2) * base * height
Area of Rectangle = 15 *18
Area of Rectangle = 270 sq.ft
Area of Triangle = (1/2) * 8 *17
Area of Triangle = 4 * 17
Area of Triangle = 68 sq.ft
Therefore, the total area = 68 +270 = 338 sq.ft.
Perimeter of a polygon is equal to sum of all the sides
= ( 15+18+17+18+8)
= 76 ft.

Mari spends $6 on cheese for a party she also plans to buy b boxes of crackers that cost $3 per box
Answer:
6+3b=x
Step-by-step explanation:
The total amount of money spend on crackers and cheese is given by the inequality 3b + 6 ≤ 15
What is an Inequality Equation?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.
Given data ,
Let the inequality equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the amount spend on cheese be = $ 6
The number of boxes of crackers = b
The cost of one box of crackers = $ 3
So , the total amount for b box of crackers = 3b
The maximum amount of money that can be spend = $ 15
And , total amount of money spend on crackers and cheese is
3b + 6 ≤ 15
Subtracting 6 on both sides , we get
3b ≤ 9
Divide by 3 on both sides , we get
b ≤ 3 boxes
Therefore , the value of b is 3 boxes
Hence , the inequality is 3b + 6 ≤ 15

Answer:
x=12 but who knows maybe
Step-by-step explanation:
if we are trying to say those lines are equal length than surely the equations must be equal value otherwise they aren't equal so we can probably set them equal to each other and solve for x right? 2x+6=3x-6 subtract 6. 2x=3x-12. subtract 3x. -1x=-12. divide by -1 so x=12.
If the vertex H of a triangle is at (- 2, 2) , what are the coordinates of H in the dilation of the triangle when the origin is the center of dilation and the scale factor is 3?
Answer:
The coordinates of H after the dilation is (-6,6)
Step-by-step explanation:
Here, we want to get the coordinates of the image given the coordinates of the pre-image
with the dilation factor and the coordinates, what we have to do is to simply multiply each of the coordinates of the point on the vertex by 3
Mathematically, we have this as;
H’ = 3H
so;
(-2,2) becomes; (3 * -2, 3 * 2) = (-6,6)
2/5 + 1/3 Can you add these fractions with the denominators they have right now?
Answer:
yes you can simplify it because both the denominators have common denominator of 15.
Answer:
Yes
Step-by-step explanation:
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.
