ANSWER
The swimming pool can hold 1,000,000 cubic feet of water.
EXPLANATION
The capacity of water the pool holds is the volume of water in the swimming pool.
The swimming pool is rectangular, therefore its volume can be calculated using the formula,
[tex]V = l \times w \times h[/tex]
where l=1000ft is the length, w=100ft is the width and h=10ft is the height of the pool.
We substitute all these values into the formula to get:
[tex]V = 1000 \times 100 \times 10 = 1000000 {ft}^{3} [/tex]
The swimming pool can hold 1,000,000 cubic feet of water.
The amount of water the pool can hold is 1,000,000 ft³.
What is the amount of water the pool can hold?In order to determine the amount of water the pool can hold, we have to determine the volume of the rectangular swimming pool. Since the swimming pool has the shape of a cuboid, the formula for the volume of a cuboid would be used.
Volume = length x width x height
1000 x 100 x 10 = 1,000,000 ft³

Melisa is throwing a birthday party for her son. She ordered 4 pizzas, she realizes that her son invited more people than she thought, so she decides to order 1 more pizza for every 3 people that come to the party. The total number of pizzas, y , can be expressed in terms of the number of people that show up to the party, x . which inequality represents this situation?
y = -one third x + 4
y = one third x + 4
y = 3x - 4
y = 3x + 4
Answer:
y = 3x + 4
Step-by-step explanation:
3x would be the number of people that show up to the party times the number of pizza's needed plus the 4 she already ordered

Given :△ABC (to the right), AB = 15, BD = 9,
AD ⊥BC m∠C = 30°. Find the perimeter of triangle.
Answer:
48 + 12√3 units
Step-by-step explanation:
ALL LENGTHS MUST BE POSITIVE (I did this to avoid writing ± and showing that only + works)
1. Find AD (you'll find why later): 15² = 9² + AD² --> AD² = 144 --> AD = 12
2. 30-60-90: 12-DC-AC --> AC = 24, DC = 12√3 (side opposite of 90 is double side opposite of 30, side opposite of 60 is √3 times the opposite of 30)
P = AB + BD + DC + AC = 15 + 9 + 12√3 + 24 = 48 + 12√3 units
The perimeter of triangle △ABC is found by summing all sides of the triangle, resulting in 51.
Explanation:In this question, we are dealing with the triangle △ABC. We know that AB = 15, BD = 9, AD is perpendicular to BC, and m∠C = 30°. Remember, the sum of all sides in a triangle constitutes the perimeter.
Given that AB=15 and BD=9, and as BD is the opposite side of m∠C = 30°, we know that the hypotenuse is twice the length of the opposite side in a 30-60-90 triangle. Thus, AD = 2BD = 18. Since AD is also perpendicular to BC, AD divides the triangle into two right triangles.
We know that the side adjacent to ∠C is half the length of the hypotenuse in a 30°-60°-90° triangle. Hence, CD = AD/2 = 18/2 = 9. Now, BC = BD + CD = 9 + 9 = 18. Summing up all sides of the triangle, the perimeter of △ABC = AB + BC + AC = 15 + 18 + 18 = 51.

The area of a triangle can be found using the formula: Area = (base × height) / 2.
Explanation:The area of a triangle can be found using the formula: Area = (base × height) / 2. To find the area of the triangle shown below, you need to know the length of the base and the height. Once you have those values, you can plug them into the formula to calculate the area.
If r(x) = 2 – x2 and w(x) = x – 2, what is the range of (w.r) (x)?
The range of (w.r)(x) is all real numbers.
Explanation:The range of (w.r)(x) can be found by substituting the value of x from w(x) into r(x). So, we have:
(w.r)(x) = r(w(x)) = 2 - (x - 2)^2 = 2 - (x^2 - 4x + 4) = 6 - x^2 + 4x.
Therefore, the range of (w.r)(x) is all real numbers.
The histogram shows the weekly attendance of participants in a school's study skills program. Student attendance numbers were the same during which two weeks of the workshop?
Student attendance numbers were the same during which two weeks of the workshop? B. weeks 2 and 4
Explanation:A histogram is the graphical display of data by using bars of different heights. Histograms provide a visual interpretation of numerical data by indicating the number of data points that lie within a range of values. Histogram was first introduced by Karl Pearson in 1891.
Some histograms presented with the independent variable along the vertical axis and dependent variable along the horizontal axis. The histogram attached below shows the weekly attendance of participants in a school's study skills program. In the histogram the x axis is number of weeks and y axis is number of students in attendance.
According to the histogram attached we can see that in week 1 the Student attendance was 8, in week 2 the Student attendance was 12, in week 3 the Student attendance was 15, in week 4 the Student attendance was 12, in week 5 the Student attendance was 18, in week 6 the Student attendance was 16. Hence the Student attendance numbers are the same during week 2 and 4 of the workshop. Therefore the correct option is B

Answer:
Step-by-step explanation:
Set up hypotheses as:
[tex]H-0: p=0.60\\H_a: p >0.60[/tex]
(Right tailed test)
Sample proportion p = favourable/total = [tex]\frac{640}{1000} =0.64[/tex]
p difference [tex]=0.64-0.60 =0.04[/tex]
Sample std error = [tex]\sqrt{\frac{pq}{n} } =\sqrt{\frac{0.64(0.36)}{1000} } \\=0.0152[/tex]
Critical value for95% = 1.96

Which expression represents the area of the rectangle
(2x+7)(4x+5)?
So we'll do FOIL (first, outer, inner, last)
The equation is (4x+5)(2x+7)
First, 4x·2x=8x²
Outer, 4x·7=28x
Inner, 5·2x=10x
Last, 5·7=35
Add like terms and you get:
8x²+38x+35
The area of the rectangle represented by the expression (2x+7)(4x+5) is calculated by distributing and combining like terms, yielding the answer 8x^2 + 38x + 35.
Explanation:The expression (2x+7)(4x+5) represents the area of rectangle in Algebra. The area of a rectangle is calculated as length times width, and in this case, the length is 2x+7 and the width is 4x+5.
To calculate the area, we will need to multiply these two expressions, also known as using the distribution property of multiplication over addition.
Apply the distributive property:
2x * 4x = 8x^22x * 5 = 10x7 * 4x = 28x7 * 5 = 35Combine like terms:
8x^2 + 10x + 28x + 35 = 8x^2 + 38x + 35.So, the area of the rectangle is represented by the expression 8x^2 + 38x + 35.

Which graph matches the equation y = -(x-2)2
The equation y = -(x-2)² represents a parabola opening downwards with a vertex at (2, 0). To find the matching graph, plot several points by calculating y for chosen x values and then connect the points to reveal the parabola's shape.
Explanation:The student is asking for the graph that matches the equation y = -(x-2)². This equation represents a parabola that opens downwards due to the negative sign in front of the parenthesis. To plot this, we'll need to create a table of values by choosing different x values, inserting them into the equation, and calculating the corresponding y values. After plotting these points, we'll see the shape of the parabola. Its vertex, the highest point on the graph due to the downward opening, will be at (2, 0) since the equation is in the form y = -a(x - h)², where (h, k) is the vertex of the parabola.
Steps for Plotting:Choose x values around the vertex (2, 0).Calculate y for each x.Plot the points on the coordinate plane.Connect the points to form a parabola.

If y is 4.5 when x is 3, and y varies directly with x, find y when x is 9. 1.5 7.5 10.5 13.5
ANSWER
13.5
EXPLANATION
It was given that, y varies directly as x.
Therefore, the variation equation is of the form:
[tex]y = kx[/tex]
If y is 4.5 when x is 3, then we can substitute to find the constant of variation.
[tex]4.5 = 3k[/tex]
Divide both sides by 3;
[tex]k = \frac{4.5}{3} [/tex]
[tex]k = \frac{3}{2} [/tex]
Hence the equation becomes:
[tex]y = \frac{3}{2} x[/tex]
When x=9,
[tex]y = \frac{3}{2} \times 9 = 13.5[/tex]
