Answer:
320 girls
Step-by-step explanation:
We can make an algebric equation for this:
5x=900
x=180
We are asked to find the girls so we have to multiply the girls ratio by our x value we just found.
4x=4x180=320 girls

Is 7.12467 rational or irrational
Answer:
Rational
Step-by-step explanation:
A rational number is a number that can be represented a/b where a and b are integers and b is not equal to 0. Since 7.12467 is an integer or decimal it's rational
A rectangular pool measures 5 yd by 6 yd. A concrete deck of uniform width is constructed around the pool. The deck and pool together cover an area of 72. How wide is the deck?
Answer:
42 yard
Step-by-step explanation:
Area of deck = total area - area of pool
area of a rectangle = length x width
5 x 6 = 30
72 - 30 = 42
A school is planning to construct two rectangular play areas in the playground. The length of play area A must be 1 foot longer than four times its width. The width of play area B must be 2 feet longer than the width of play area A, and the length must be 2 feet longer than three times its own width. In addition, the areas of the two play areas must be equal. Write a system of equations to represent this situation, where y is the area of the play areas and x is the width of play area A. Which statement describes the number and viability of the system's solutions?
Answer:
А.The system has two solutions, but only one is viable because the other results in a negative width.
Step-by-step explanation:
Given
Let:
[tex]L_A \to[/tex] length of play area A
[tex]W_A \to[/tex] width of play area A
[tex]L_B \to[/tex] length of play area B
[tex]W_B \to[/tex] width of play area B
[tex]x \to[/tex] Area of A
[tex]y \to[/tex] Area of B
From the question, we have the following:
[tex]L_A = 1 + 4W_A[/tex]
[tex]W_B = 2 + W_A[/tex]
[tex]L_B = 2 + 3W_B[/tex]
[tex]x = y[/tex]
The area of A is:
[tex]x = L_A * W_A[/tex]
This gives:
[tex]x = (1 + 4W_A) * W_A[/tex]
Open bracket
[tex]x = W_A + 4W_A^2[/tex]
The area of B is:
[tex]y = L_B * W_B[/tex]
[tex]y = (2 + 3W_B) * ( 2 + W_A)[/tex]
Substitute: [tex]W_B = 2 + W_A[/tex]
[tex]y = (2 + 3(2 + W_A)) * ( 2 + W_A)[/tex]
Open brackets
[tex]y = (2 + 6 + 3W_A) * ( 2 + W_A)[/tex]
[tex]y = (8 + 3W_A) * ( 2 + W_A)[/tex]
Expand
[tex]y = 16 + 8W_A + 6W_A + 3W_A^2[/tex]
[tex]y = 16 + 14W_A + 3W_A^2[/tex]
We have that:
[tex]x = y[/tex]
This gives:
[tex]W_A + 4W_A^2 = 16 + 14W_A + 3W_A^2[/tex]
Collect like terms
[tex]4W_A^2 - 3W_A^2 + W_A -14W_A - 16 =0[/tex]
[tex]W_A^2 -13W_A - 16 =0[/tex]
Using quadratic calculator, we have:
[tex]W_A = -14.1[/tex] or [tex]W = 1.13[/tex] --- approximated
But the width can not be negative; So:
[tex]W = 1.19[/tex]

You just brought a tank for your fishes. You have a height of 6ft. The length is 5times the width w. The volume of the tank is 600 ft^3. What is the width of the tank to the nearest tenth of a foot? The formula is V = (l)(w)(h)
Answer:
w = 20 feet
Step-by-step explanation:
V = lwh
600 = 5(6)w
600 = 30w
w = 20
12. The circumference of circle T is 180x units.
What is the area of the shaded sector?
Answer:900 square units
Step-by-step explanation:
The radius is 90 units. Then the area of the shaded sector will be 900π square units.
What is the area of the sector?Let r be the radius of the sector and θ be the angle subtended by the sector at the center. Then the area of the sector of the circle will be
A = (θ/360°) πr²
The circumference of circle T is 180π units. Then the radius of the circle is given as,
C = 180π
2πr = 180π
r = 90 units
Then the area of the sector is given as,
A = (40°/360°) π x 90²
A = 900π square units
The area of the shaded sector will be 900π square units.
More about the area of the sector link is given below.

Classify the function as linear or quadratic and identify the quadratic, linear, and constant terms.
f(x) = 6x2 + x − 12
A. quadratic function; quadratic term: −12x2; linear term: −6x; constant term: −12
B. linear function; linear term: x; constant term: −12
C. linear function; linear term: 6x2; constant term: −12
D. quadratic function; quadratic term: 6x2; linear term: x; constant term: −12
Answer:
D
Step-by-step explanation:
The function f(x) = 6x2 +x -12 is a quadratic since the highest degree polynomial term is 2. So that eliminates B and C. Option A is incorrect because the quadratic term is 6 not double the constant. There for the correct choice is D because the function is a quadratic and the quadratic term is 6x2, the linear term is x and the constant term is -12.

Gabrielle cut a square cake vertically to make two rectangle slices. Each rectangle had a perimeter of 33 inches. How long is each side of the original square cake?
Answer:
11 inches
Step-by-step explanation:
Perimeter of each rectangle = 33 inches
The square cake is cut in half
which means two half sides would equal one whole side.
2 × 1/2 = 1
The two "halves" in the smaller rectangle would equal one whole side + the two whole sides in the smaller rectangle
1 + 2 = 3
Each side of the original square cake = 33 inches / 3
= 11 inches
Each side of the original square cake = 11 inches
Use the rectangle to answer the question.

What is the area of the rectangle?

Answer:
12 x 9 = 108
Step-by-step explanation:
Just multiply the 2 given lengths when finding AREA of a rectangle.
Answer:
D.108
Step-by-step explanation:
use the figure below to answer the question
Answer:
Sin(Ф) = Opposite / Hypotenuse
We know that Opposite = 6, and
Hypotenuse = 3/4 or 0.75
So,
Sin(Ф) = 6 / 0.75
Sin(Ф) = 8
So the value of sin of Ф would be 8

A teacher would like to estimate the mean number of steps students take during the school day. To do so, she selects a random sample of 50 students and gives each one a pedometer at the beginning of the school day. They wear the pedometers all day and then return them to her at the end of the school day. From this, she computes the 98% confidence interval for the true mean number of steps students take during the school day to be 8,500 to 10,200. If the teacher had used a 90% confidence interval rather than a 98% confidence interval, what would happen to the width of the interval
Answer:
The answer is "It would decrease, but not necessarily by 8%".
Step-by-step explanation:
They know that width of the confidence level is proportional to a confidence level. As just a result, reducing the confidence level decreases the width of a normal distribution, but not with the amount of variance in the confidence level. As just a result, when a person teaches a 90% standard deviation rather than a 98 percent normal distribution, the width of the duration narrows.

Find the value of x in the following diagram.
Answer:
x = 3.5
Step-by-step explanation:
By definition, congruent chords are equidistant from the center of a circle. We are given two congruent chords and their distances(the lines perpendicular), meaning those distances must be equal. We set set up an equation to model the situation:
x + 8 = 3x + 1
8 = 2x + 1
2x = 7
x = 3.5
