The center of your park has a pool. The pool is the shape of a rectangular prism. The volume of the pool is 189 cubic feet. If the length of the pool is 7 yards and the width is 3 yards, how deep is the pool? (Hint: 3 feet = 1 yard)
Answer:
3 yards
Step-by-step explanation:
First, let's convert yards into feet. 189 feet is 63 yards.
Volume=L•W•H L=length W=width H=height
To do this we have to divide the volume by the product of the length and width and it will calculate the height.
Solving for the width:
63÷(7•3)=3 yards <-the depth of the pool
Answer:
3 yards

Which best explains whether or not triangles RST and ACB are congruent?
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the x-axis and a translation 2 units to the left.
The figures are congruent. ΔRST can be mapped to ΔACB by a reflection over the y-axis and a translation 2 units down.
The figures are not congruent. Point R corresponds to point A, but S corresponds to B and T corresponds to C.
The figures are not congruent. Point R does not correspond with point A.
Answer:
Correct option: first one
Step-by-step explanation:
If we reflect the triangle RST over the x-axis, the y-coordinate of each point will have the sign switched, so the point S would be in (1, -5), the point R would be in (1, -1) and the point T would be in (4, -1)
Then, if we translate the resulting points 2 units to the left, we would have:
S = (-1, -5) -> matches point C
R = (-1, -1) -> matches point A
T = (2, -1) -> matches point B
So the triangles are congruent, and we can map from triangle RST to triangle ACB with a reflection over the x-axis and a translation of 2 units to the left.
Correct option: first one

What is the value of A and B and if you can please show how you got that answer
Answer:
a = 4.5 units
b = 7.5 units
Step-by-step explanation:
By using mean proportional theorem in the ΔACB,
ΔACB ~ ΔADC ~ ΔCDB
[tex]\frac{AD}{CD}=\frac{CD}{DB}[/tex]
[tex]\frac{8}{6}=\frac{6}{a}[/tex]
a = [tex]\frac{6\times 6}{8}[/tex]
a = 4.5
[tex]\frac{AB}{CB}=\frac{CB}{DB}[/tex]
[tex]\frac{(a+8)}{b}=\frac{b}{a}[/tex]
Since a = 4.5
[tex]\frac{4.5+8}{b}=\frac{b}{4.5}[/tex]
b² = 4.5 × 12.5
b = √56.25
b = 7.5 units
Therefore, a = 4.5 units and b = 7.5 units will be the answer.

A rectangular flower garden in Samantha’s backyard has 260 feet around its edge the with garden is 60 What is the length of the garden
Answer:
70 ft
Step-by-step explanation:
260 feet around its edge means perimeter
P = 2(l+w)
Width = 60
260 = 2( l+60)
Divide each side by 2
260/2 = 2/2(l+60)
130 = l+60
Subtract 60 from each side
130-60 = l+60-60
70 = l
The length is 70 ft
Abigail can read 180 words in one minute if she were to read 30 minutes each day how many days would it take to read 32,400 words of a book
Answer:
It would take Abigail six days to read 32,400 words of a book if she were to read 30 minutes per day.
Step-by-step explanation:
If Abigail reads 180 words per minute, and she reads 30 minutes per day, we need to multiply 180 by 30 to figure out how many words she reads per day.
180 × 30 = 5,400
Abigail reads 5,400 words per day.
Then, we divide 32,400 by 5,400 to figure out how many days it would take Abigail to read 32,400 words.
32,400 ÷ 5,400 = 6
It would take Abigail six days to read 32,400 days.

Which linear function is represented by the graph?
Answer:
y[tex]\leq[/tex][tex]\frac{1}{3}[/tex]x-4; B
Step-by-step explanation:
The blue is in the y-values where it is more directed towards the negative y- values.
y=mx+b
[tex]\frac{1}{3}[/tex] slope= because rise is 1 and 3 runs and to find slope it is [tex]\frac{rise}{run}[/tex]
-4 is the "b" in y=mx+b where b represents the y-intercept and looking at the graph, the line intercepts at -4

y=x^{2} +2x-8 determine the axis of symmetry, the vertex point and find the roots by factoring
Answer:
x = -1 <--- axis of symmetry
(-1, -9) <-- vertex
2, -4 (or, in my old precalc class we wrote our roots as (2,0) and (-4,0)) <--- roots
Step-by-step explanation:
a) Axis of symmetry equation is defined as
[tex]-b/2a[/tex] = x (i memorized this)
Quadratic equation form:
[tex]ax^2+bx+c[/tex]
And our original equation:
[tex]x^2+2x-8[/tex]
So..
[tex]-2/2 = - 1[/tex]
So our axis of symmetry is at x = -1,
b) now vertex point can be found by plugging this value back into our original equation.
y = [tex](-1)^2+2(-1)-8[/tex]
y = 1 - 2 - 8
y = - 9
So our vertex is at (-1, -9)
c) Finally, lets factor
[tex]x^2+2x-8[/tex] = 0 (when finding the roots, set y = 0, because we are trying to find where we cross the x-axis)
[tex]x^2-2x+4x-8[/tex] = 0
[tex]x(x-2) + 4(x-2) = 0[/tex]
[tex](x-2)(x+4)=0[/tex]
x = 2; x = -4 <--- Roots

1.) A school wants to have a metal gate placed around it. However they only want to cover three sides of the school and they only have 2000 feet of gate. What are the dimensions of the school if the area is 240,000 square feet?
2.) A backyard is in the shape of a rectangle. The distance around the yard is 280 feet and it has an area of 2,400 square feet. What are the dimensions of the yard?
Answer:
I only have an answer to number 2 but the dimensions are 20 and 120.
Step-by-step explanation:
well you can remove the zeroes and factor either the 28 or 24. (I think 24 is the best) so when you factor it you get 2 and 12 because 2 x 12 is 24 and 2 + 2 + 12 + 12 is 28. Then add the zeroes and you have your dimensions. I hope that explanation helped with number 2.

Required
Calculate the relative frequency of the class with lower limit 27
Relative Frequency is calculated by dividing individual frequency by the total frequency
Mathematically,
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex]
The total frequency of the given data is 6+8+4+2+5+2
[tex]Total\ Frequency = 27[/tex]
The class with lower limit 27 has a frequency of 2;
Hence;
[tex]Relative\ Frequency = \frac{Individual\ Frequency}{Total\ Frequency}[/tex] becomes
[tex]Relative\ Frequency = \frac{2}{27}[/tex]
[tex]Relative\ Frequency = 0.07407407407[/tex]
[tex]Relative\ Frequency = 0.0741[/tex] (Approximated)
You may also leave your answer in percentage form
[tex]Relative\ Frequency = 0.0741 * 100\%[/tex]
