Answer:
a) The percent of their games the hockey team won is 60%
b) The percent of their games the hockey team lost is 37% to the nearest percent
c) The percent of their games the hockey team tied is 3% to the nearest percent
Step-by-step explanation:
In any game, there are 3 situations
WinTie LoseThe sum of the three situations is the total number of playing that game
∵ The hockey team won 72 out of 120 games and tied 4
∴ The number of winning games = 72
∴ The number of tying games = 4
∴ The number of total games = 120
→ Find the number of losing games
∵ Win + ty + lose = total games
∴ 72 + 4 + lose = 120
∴ 76 + lose = 120
→ Subtract 76 from both sides
∴ lose = 44
∴ The number of losing games = 44
Now let answer the questions
a)
∵ P%(win) = (winning ÷ total) × 100%
∴ P%(win) = (72 ÷ 120) × 100%
∴ P%(win) = 60%
The percent of their games the hockey team won is 60%
b)
∵ P%(lose) = (losing ÷ total) × 100%
∴ P%(lose) = (44 ÷ 120) × 100%
∴ P%(lose) = 36.66667% = 37% to the nearest percent
The percent of their games the hockey team lost is 37% to the nearest percent
c)
∵ P%(tie) = (tying ÷ total) × 100%
∴ P%(tie) = (4 ÷ 120) × 100%
∴ P%(tie) = 3.333333% = 3% to the nearest percent
The percent of their games the hockey team tied is 3% to the nearest percent

Explanation:
The old dimensions of the rectangle were 30 by 15.
The new dimensions are 30+x by 15+x, where x is some positive number.
The new rectangle dimensions multiply to 1000
(30+x)(15+x) = 1000
Use the FOIL rule to expand out the left side like so
(30+x)(15+x) = 1000
450+30x+15x+x^2 = 1000
450+45x+x^2 = 1000
x^2+45x+450
Then lets get everything to one side
x^2+45x+450 = 1000
x^2+45x+450-1000 = 0
x^2+45x-550 = 0
---------------------
From here we use the quadratic formula
Plug in a = 1, b = 45, and c = -550.
[tex]x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\x = \frac{-(45)\pm\sqrt{(45)^2-4(1)(-550)}}{2(1)}\\\\x = \frac{-45\pm\sqrt{4225}}{2}\\\\[/tex]
[tex]x = \frac{-45\pm65}{2}\\\\x = \frac{-45+65}{2} \ \text{ or } \ x = \frac{-45-65}{2}\\\\x = \frac{20}{2} \ \text{ or } \ x = \frac{-110}{2}\\\\x = 10 \ \text{ or } \ x = -55\\\\[/tex]
Earlier we defined x to be a positive number. This means we ignore x = -55. It makes no sense to add on a negative amount to each dimension.
The only practical answer is x = 10.
So each dimension is increased by 10 feet.
--------------------------
If x = 10, then the old dimensions of 30 by 15 bump up to 30+10 = 40 by 15+10 = 25
Then note how 40*25 = 1000, which helps confirm we have the correct dimensions.
--------------------------
Now go back to the question at hand: we want to find the new width. The old width was 30 feet. The new width is 30+x = 30+10 = 40 feet

Let football cost be f and basketball cost be b
We have two equations as per given:
5f + 14b = 11010f + 6b = 82.50We need to find b, therefore we'll eliminate f
To do so we'll double the first equation and subtract the second one:
2(5f + 14b) - (10f + 6b) = 2(110) - 82.5028b - 6b = 220 - 82.5022b = 137.5b = 137.5/22b = 6.25Each basketball costs $6.25

Step-by-step explanation:
Alex buys x oranges and Bobbie buys x + 2 oranges. Together they buy 2x + 2 oranges.
$4.20 / $0.21 = 20 oranges.
2x + 2 = 20
2x = 18
x = 9
Hence the value of x is 9.
Answer:
x=9
Step-by-step explanation:
The total number of oranges purchased is x + x+2 = 2x+2
They cost 21 cents each
(2x+2) *.21
This is equal to 4.20
(2x+2) *.21 =4.20
Divide each side by .21
(2x+2) *.21/.21 =4.20/.21
2x+2 = 20
Subtract 2 from each side
2x+2-2 =20-2
2x= 18
Divide by 2
2x/2 =18/2
x =9

The gardening store sells clay flower pots, which hold 2 litres of dirt, and ceramic flower pots, which hold 7 litres. Tara bought 35 flower pots, which will hold a total of 150 litres of dirt. How many of each flower pot did she buy?
Answers
Answer:
The number of clay flower pots = x = 19
The number of ceramic flower pots = y = 16
Step-by-step explanation:
Let
The number of clay flower pots = x
The number of ceramic flower pots = y
Tara bought 35 flower pots
= x + y = 35
x = 35 - y
The gardening store sells clay flower pots, which hold 2 litres of dirt, and ceramic flower pots, which hold 7 litres. Tara bought 35 flower pots, which will hold a total of 150 litres of dirt.
Hence:
2x + 7y = 150.... Equation 2
Substitute 35 - y for x in Equation 2
2 (35 - y) + 7y = 150
70 - 2y + 7y = 150
-2y + 7y = 150 - 70
5y = 80
y = 80/5
y = 16 flower pots
x = 35 - y
x = 35 - 16
x = 19 flower pots
The number of clay flower pots = x = 19
The number of ceramic flower pots = y = 16
Answer:
The number of clay flower pots = 19
The number of ceramic flower pots = 16

The leg of a right triangle is 2 units and the hypotenuse is 4 units. What is the length, in units, of the other leg of the triangle? (5 points)
2 units
6 units
Square root of 12 units
Square root of 20 units
Answers
Answer:
[tex]\sqrt{12}[/tex] units
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.
let x be the other leg, then
x² + 2² = 4²
x² + 4 = 16 ( subtract 4 from both sides )
x² = 12 ( take the square root of both sides )
x = [tex]\sqrt{12}[/tex] units
which can be simplified to 2[tex]\sqrt{3}[/tex] units , if required.
Given the graphed function below, which of the following ordered pairs are
found on the inverse function?
Answers
Answer: Option B.
Step-by-step explanation:
A linear function can be written as:
y = a*x + b
where a is the slope and b is the y-intercept.
if the line passes through the points (ax, ay) and (bx, by) then the slope is:
a = (bx - ax)/(by - ay)
In this case, we can see that the line passes through the points:
(1, 3) and (2, 1)
Then the slope is:
a = (1 - 3)/(2 - 1) = -2
y = -2*x + b
In the graph we also can see that the line intersects the y-axis at y = 5, then b = 5.
The line is:
y = f(x) = -2*x + 5.
the inverse function is such that:
g( f(x)) = x
to find the inverse function of a linear equation, we just could isolate x.
y - 5 = -2x
-y/2 + 2.5 = x
Then we could write the inverse function as:
g(x) = - x/2 + 2.5
Now we need to see which pairs belong to this line. I just will evaluate the function g(x) in different values of x, and see which points belong to the line.
g(9) = -9/2 + 2.5 = -4.5 + 2.5 = -2
(9, -2) belongs to the line.
g(7) = -7/2 + 2.5 = -3.5 + 2.5 = -1
Then (7, -1) belongs to this line.
g(5) = -5/2 + 2.5 = 0
Then the point (5, 0) belong to this line.
We can already see that all these points are in option B, then option B is the correct one.

Answer:
y=-7x-2
Step-by-step explanation:
I assume you need the equation for the line, so that's what I'm solving for here.
1. Start by putting the slope and the coordinates into point slope form, which is y-y1=m(x-x1)
y+30=-7(x-4)
2. Distribute -7 to (x-4) (or multiply x and -4 by -7).
y+30=-7x+28
3. Subtract 30 from both sides to get y by itself.
y=-7x-2

A line with a negative slope is perpendicular to one of the lines shown. What is its slope? Use the graph shown below. The slope is:
Answers
Given:
A line is perpendicular to the given line and having negative slope.
To find:
The slope of the line.
Solution:
We know that, product of slopes of two perpendicular lines is -1.
[tex]m_1\cdot m_2=-1[/tex]
[tex]m_1=-\dfrac{1}{m_2}[/tex]
It means, one slope is opposite and reciprocal of other.
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
From the given graph it is clear that, blue line passes through (0,3) and (2,4). So, slope of blue line is
[tex]m_B=\dfrac{4-3}{2-0}[/tex]
[tex]m_B=\dfrac{1}{2}[/tex]
The slope of blue line is [tex]\dfrac{1}{2}[/tex]. So, slope of the line which is perpendicular to the blue line is -2, which is negative.
From the given graph it is clear that, red line passes through (0,4) and (4,3). So, slope of red line is
[tex]m_R=\dfrac{3-4}{4-0}[/tex]
[tex]m_R=\dfrac{-1}{4}[/tex]
The slope of blue line is [tex]-\dfrac{1}{4}[/tex]. So, slope of the line which is perpendicular to the blue line is 4, which is positive.
Therefore, the slope of the line which is perpendicular to the given line and having negative slope, is -2.

The graph of a linear relationship passes

through (2, 7). Which of the following is
the equation for this linear relationship?
A y= 2x + 3 Cy=5x
B y = 3x + 2
Dy= 4x - 1
Answers
Answer:
The equation of the linear relationship is y = 3x + 2 ⇒ B
Step-by-step explanation:
To solve the question substitute the x in the equation by the x-coordinate of each point to find y, if y equals the y-coordinate of the point, then the point is on the graph of the equation
A.
∵ y = 2x + 3
→ Use the first point (0, 2)
∵ x = 0
→ Substitute x by 0 in the equation
∴ y = 2(0) + 3
∴ y = 0 + 3 = 3
∵ The y-coordinate is 2
∴ The point (0, 2) does not lie on the graph of the relationship
∴ The equation y = 2x + 3 doesn't represent the equation of the relationship
B.
∵ y = 3x + 2
→ Use the first point (0, 2)
∵ x = 0
→ Substitute x by 0 in the equation
∴ y = 3(0) + 2
∴ y = 0 + 2 = 2
∵ The y-coordinate is 2
∴ The point (0, 2) lies on the graph of the relationship
→ Use the second point (1, 5)
∵ x = 1
→ Substitute x by 1 in the equation
∴ y = 3(1) + 2
∴ y = 3 + 2 = 5
∵ The y-coordinate is 5
∴ The point (1, 5) lies on the graph of the relationship
→ Use the third point (3, 11)
∵ x = 3
→ Substitute x by 3 in the equation
∴ y = 3(3) + 2
∴ y = 9 + 2 = 11
∵ The y-coordinate is 11
∴ The point (3, 11) lies on the graph of the relationship
→ Use the fourth point (2, 7)
∵ x = 2
→ Substitute x by 2 in the equation
∴ y = 3(2) + 2
∴ y = 6 + 2 = 8
∵ The y-coordinate is 7
∴ The point (2, 7) doesn't lie on the graph of the relationship
∴ The equation of the linear relationship is y = 3x + 2
