Answer:
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.
Step-by-step explanation:
By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:
Community swimming pool
[tex]V_{c} = l\cdot w\cdot h[/tex] (1)
Wading pool
[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w[/tex] (2)
Where:
[tex]l[/tex] - Length of the swimming pool, measured in feet.
[tex]h[/tex] - Depth of the swimming pool, measured in feet.
[tex]w[/tex] - Width of the swimming pool, measured in feet.
[tex]V_{c}[/tex] - Volume of the community swimming pool, measured in cubic feet.
[tex]V_{w}[/tex] - Volume of the wading swimming pool, measured in cubic feet.
The ratio of the volume of the community swimming pool to the volume of the wadling pool is:
[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w}[/tex] (3)
[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]
[tex]\frac{V_{c}}{V_{w}} = 4[/tex]
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Daniel wanted to make note cards by cuttin pieces of paper in half. before starting he got 3 more pieces to use. when he was done he had 20 half pieces of paper. with how many pieces did he start
Answer:
7
Step-by-step explanation:
If he ended up with 20 half pieces, then he cut 10 pieces in half since 20/2 = 10.
Before starting to cut he got 3 more pieces, so he had 3 fewer than 10.
Answer: He started with 7 pieces of paper.
Check:
Start with 7 pieces of paper.
Add 3 pieces of paper to end up with 10 pieces of paper.
Cut the 10 pieces of paper to end up with 20 half pieces.
He did end up with 20 half pieces, so he started with 7.

Answer:
6.2 cm
Step-by-step explanation:
Apply the Law of cosines, given as:
c² = a² + b² - 2ab×Cos(C)
Where,
a = 4 cm
b = 8 cm
c = AB = ??
C = 50°
Plug in the value into the equation
c² = 4² + 8² - 2*4*8*Cos(50)
c² = 16 + 64 - 64*Cos(50)
c² = 80 - 64*Cos(50)
c² = 38.861593
c = √38.861593
c = 6.2 cm (nearest tenth)

1. a) A glass candy jar weighs 450 grams when empty. It is then filled with
Jolly Ranchers. One Jolly Rancher weighs 6 grams. Write an equation to
represent the relationship between the total weight of the jar in
and the number of Jolly Ranchers, J.*
grams, W,
Your answer
This is a required question
Answer:
w = 6j + 450 129 Jolly RanchersStep-by-step explanation:
a) Total weight comprises of the weight of jar plus weight of Jolly Ranchers
w = 6j + 450 is the required equationb) When the candy jar is full, it weighs 1224 grams. How many Jolly Ranchers can the jar hold?
Given w = 1224, then to find j we solve the equation:
1224 = 6j + 4506j = 1224 - 4506j = 774j = 774/6j = 129The jar can hold 129 Jolly Ranchers
Solve: 5(w +2.2) – 4w = 9.3.

Answer:
w = -1.7
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Property
Step-by-step explanation:
Step 1: Define
5(w + 2.2) - 4w = 9.3
Step 2: Solve for w
Distribute 5: 5w + 11 - 4w = 9.3Combine like terms: w + 11 = 9.3Isolate w: w = -1.7Step 3: Check
Plug in w into the original equation to verify it's a solution.
Substitute in w: 5(-1.7 + 2.2) - 4(-1.7) = 9.3(Parenthesis) Add: 5(0.5) - 4(-1.7) = 9.3Multiplication: 2.5 + 6.8 = 9.3Addition: 9.3 = 9.3Here we see that 9.3 does indeed equal 9.3.
∴ w = -1.7 is the solution to the equation.

8x - 6y = -20
-16х +7 y = 30
Answer:
8x - 6y = 20-16х +7 y = 30
Step-by-step explanation:
Answer:
(-1,2)
Step-by-step explanation:
multiply top equation by 2 and add them together as follows
16x-12y=-40
-16x+7y=30
-5y=-10
y=2
now replace y with 2 in the first equation and solve for x
8x-6(2)=-20
8x-12=-20
8x=-8
x=-1
the problem you chose:
2x2+2x-12 = 0
x = 4
Simplifying the equation...
2(2) + 2x - 12 = 0, 2x - 8 = 0, x = 4

Which of the following ratios are equivalent to 60%?
Check all that apply.
D A. 15:25
D B. 4:6
C. 3:5
D. 10:20
OE. 12:36
Answer:
its A and C
Step-by-step explanation:
The ratios that are equivalent to 60% are 15:25 and 3:5.
The correct options are A and c.
What is ratio?A ratio is a numerical relationship showing how often one value includes or is included inside another. It is used to compare two numbers.
To determine which ratios are equivalent to 60%, we can first convert 60% to a fraction or decimal.
To convert 60% to a fraction, we can write it as 60/100 and simplify by dividing both the numerator and denominator by their greatest common factor, which is 20.
This gives us 3/5.
To convert 60% to a decimal, we can divide 60 by 100, which gives us 0.6.
Now, we can check which ratios are equivalent to 60% by simplifying them and seeing if they result in 3/5 or 0.6.
A. 15:25 can be simplified by dividing both the numerator and denominator by 5, giving us 3:5, which is equivalent to 60%.
B. 4:6 can be simplified by dividing both the numerator and denominator by 2, giving us 2:3. To check if this ratio is equivalent to 60%, we can convert it to a fraction by writing it as 2/3. To see if this is equivalent to 3/5, we can cross-multiply and simplify:
2/3 = x/100
Multiplying both sides by 100:
200/3 = x
Approximating 200/3 to the nearest whole number gives us 67. Therefore, the ratio 4:6 is not equivalent to 60%.
C. 3:5 is already in the form of a ratio equivalent to 60%.
D. 10:20 can be simplified by dividing both the numerator and denominator by 10, giving us 1:2. To check if this ratio is equivalent to 60%, we can convert it to a fraction by writing it as 1/2. This is not equivalent to 3/5, so 10:20 is not equivalent to 60%.
E. 12:36 can be simplified by dividing both the numerator and denominator by 12, giving us 1:3. To check if this ratio is equivalent to 60%, we can convert it to a fraction by writing it as 1/3. This is not equivalent to 3/5, so 12:36 is not equivalent to 60%.
Therefore, the ratios that are equivalent to 60% are A and C.

So there teams and you had to put the highest value and the lowest ones the numbers are 20 -25 -10 25 -15 how would you put them in order
Answer:
25, 20, -10, -15, - 25
Step-by-step explanation:
first you start with the positive so since its going from Highest to Lowest the positive would always come first, So you would start with 25 since its your highest number and then get to 20. Now the negatives are the same just with the Negative (-) sign, so just do it like how you would with the positive numbers by counting up so first would be -10 and then your next one.

According to the chi square test, a hypothesis may be accepted if the difference between observed and expected results is __
Answer:
Close to zero
Step-by-step explanation:
In chi Square test, we accept the hypothesis If the sum of the weighted squared deviations is small.
This is because If the sum of the weighted squared deviations is small, it will mean that the observed frequencies will be close in value to the expected frequencies and therefore, there would be no need to reject the the hypothesis. However, when the sum is large, there will be need to question the hypothesis or claim made.
Thus, the hypothesis may be accepted if the difference between observed and expected results is close to zero

Actual length of car = [tex]14\frac{5}{8} \ feet[/tex] = 14.625 feet
Scale 4 inches = 3 feet

Length of model car = 19.5 inches
Which geometric figure has 120 rotational symmetry?
A. rhombus
B. regular pentagon
C. square
D. equilateral triangle
Answer:
D
Step-by-step explanation:
An equilateral triangle, and all regular polygons with 3n sides, thus D.
A figure that has 120 rotational symmetry will look exactly the same after the figure is rotated by 120 degrees. An equilateral triangle has 120 rotational symmetry.
When a rhombus, a regular pentagon or a square is rotated by 120 degrees, the resulting shapes do not have the same layout as the initial shape.
However, an equilateral triangle will look the same when rotated by 120 degrees.
I've added an attachment that illustrates the rotation by 120 degrees of an equilateral triangle.
From the attached figures, you can see that points ABC on figure 1 and are changed on figure 2 ; however, both triangles maintain the same layout.
Hence, an equilateral triangle has 120 degrees rotational symmetry
