2. Bart sold 5 more than 3 times as many refrigerators last month than the number of
refrigerators sold by Bill. If together they sold 125 refrigerators last month, how many did
each person sell?
Answer:
Bart 95 bill 30
Step-by-step explanation:
Bill=b
Bart = (3b+5)
b+ (3b+5) = 125
4b=120
b=30 Bill sold 30 refrigerators
3(30)+5 = 95 (Bart sold 95 refrigerators)
95+30=125

Students were asked how many pairs of shoes they owned. Their responses were 8, 2, 1, 5, 7, 6, 2, 2, 8, and 3.
The mean of the data is .
I think this is the answer .
Answer:
4.4
Step-by-step explanation:
Felix buys five vests for $22 each, three pairs of shoes for $50 each, and six hats for
$17 each.
What is the mean amount that he spent?
$34.62
$32.81
$25.86
$22
Answer:
25.86
Step-by-step explanation:
22 * 5 = 110
50 * 3 = 150
17 * 6 = 102
110 + 150 + 102 = 362
362 / 14 = 25.86
Find the distance between the two points in simplest radical form.
(-8,3) and (-2,-5)
Here we would be using distance formula to calculate the distance between those two points.
Points are,
(-8,3) (-2,5)★ Distance Formula :
[tex]\huge \large \boxed{\sf{{d \: = \: \sqrt{(x _{2} - x _{1}) {}^{2} \: + \: (y _{2} - y _{1}) {}^{2} }}}} \: \red\bigstar[/tex]We have :
x1 = -8 x2 = -2 y1 = 3 y2 = -5Substituting the values in the formula :
Refer the attachment.The distance between the pair of points (-8,3) and (-2,-5) in radical form is √100.
What is the distance between the pair of points?The distance formula can be expressed as:
[tex]d = \sqrt{( x_2 - x_ 1 )^2 + ( y_2 - y_1 )^2}[/tex]
Given the coordinates of the pair of points:
Point 1( -8,3 )
x₁ = -8
y₁ = 3
Point 2( -2,-5 )
x₂ = -2
y₂ = -5
Plug the coordinates into the distance formula and simplify.
[tex]d = \sqrt{( x_2 - x_ 1 )^2 + ( y_2 - y_1 )^2}\\\\d = \sqrt{( -2 - (-8) )^2 + ( -5 - 3 )^2}\\\\d = \sqrt{( -2 + 8 )^2 + ( -5 - 3 )^2}\\\\d = \sqrt{( 6 )^2 + ( -8 )^2}\\\\d = \sqrt{36 + 64}\\\\d = \sqrt{100}[/tex]
Therefore, the distance is √100 units.

Step-by-step explanation:
Hope this helps!
Answers:
Choice A) SquareChoice B) PentagonChoice D) TrapezoidChoice E) HexagonChoice F) RectangleChoice G) TriangleIn other words, it's nearly everything except choice C (octagon).
==========================================================
Explanation:
Search out "Cross sections of a cube" and you'll see visual examples of what is possible.
Here are the list of possible cross sections
SquarePentagonTrapezoidHexagonRectangleTriangleA parallelogram is also possible, but that isn't one of the listed choices so we can ignore it. The triangle can either be equilateral or won't be, depending how the cross section plane is oriented.
Nearly every box is checked except for the octagon, because we simply don't have enough faces to get 8 sides needed for the cross section.
What is 24% of 234 and it has to be 20 characters long
Answer:
56.16
We need to determine 24% of 234 now and the procedure explaining it as such
Step 1: In the given case Output Value is 234.
Step 2: Let us consider the unknown value as x.
Step 3: Consider the output value of 234 = 100%.
Step 4: In the Same way, x = 24%.
Step 5: On dividing the pair of simple equations we got the equation as under
234 = 100% (1).
x = 24% (2).
(234%)/(x%) = 100/24
Step 6: Reciprocal of both the sides results in the following equation
x%/234% = 24/100
Step 7: Simplifying the above obtained equation further will tell what is 24% of 234
x = 56.16%
Therefore, 24% of 234 is 56.16

For which values of x is the expression undefined
Answer:
x = -7
Step-by-step explanation:
Any expression is undefined when a nonzero number is in the numerator and the denominator = 0. For this expression, set the denominator = to 0 and solve for x:
x + 7 = 0
x = -7
At x = -7, this expression is undefined.

4x+11y=7
4x+3y=-1
what are the steps
Answer:
x = -1, y = 1
Step-by-step explanation:
Given that:
[tex]\begin{bmatrix}4x+11y=7\\ 4x+3y=-1\end{bmatrix}[/tex]
Isolate x for 4x + 11y = 7 which ⇒ [tex]x=\frac{7-11y}{4}[/tex]
Substitute [tex]x=\frac{7-11y}{4}[/tex] into the equation: which is:
[tex]\begin{bmatrix}4\cdot \frac{7-11y}{4}+3y=-1\end{bmatrix}[/tex]
Drop Down to:
[tex]\begin{bmatrix}7-8y=-1\end{bmatrix}[/tex]
Isolate y for 7-8y = -1: y = 1
Thus, [tex]x=\frac{7-11y}{4}[/tex]
Substitute y = 1
Hence,
[tex]x=\frac{7-11\cdot \:1}{4}=-1[/tex]
Solution ⇒ x = -1 and y = 1
~learn with lenvy~
Answer:
x = -1 , y = 1
Step-by-step explanation:
Starting with x
x = 7 - 11y/4
4 × 7-11y/4 + 3y = -1
7 - 8y = -1
Now for y
7-8y = -1 ⇒ y = 1
Hence, x = -1 and y = 1

Answer:
5 hoursStep-by-step explanation:
The question isThe tourists walked a distance of 22 km during a day.
The first 3 hours they walked with the speed of 4 km/h and the rest of the distance with the speed of 5 km/h.
What was the total time they walked.
----------------------
Let the time the tourists walked with 5 km/h is t, then we have the following equation for the total distance
3*4 + t*5 = 22Solve for t
12 + 5t = 225t = 22 - 125t = 10t = 2The total time was

Step-by-step explanation:
Suppose that the first four moves of a tic-tac-toe game are as shown.
Does the first player (whose moves are marked by Xs) have a strategy that will always win? (If no, explain why. If yes, show the winning strategy in a form of a game tree)
The first player using Xs does indeed have a strategy to always win by placing an X in the Middle right box.
Why is this a winning strategy?When the first player places an X in the middle right spot, the second player will have to place an O in two places to avoid the first player winning.
They would have to place an O in the middle left space and in the bottom right space. Seeing as they can't place an O in two boxes at once, the first player will be able to place an X in the empty box out of the two, and win.
In conclusion, there is a winning strategy.

Rachel made $176 for 11 hours of work.
At the same rate, how many hours would she have to work to make $128?
Answer:
8 hours
Step-by-step explanation:
11 hours = $176
⇒ 1 hour = $176 ÷ 11 = $16
To determine how many hours she would have to work to make $128, divide $128 by $16:
⇒ number of hours = $128 ÷ $16
= 8 hours

bought a 45-inch television. The size of the TV is measured diagonally.
The television has a height of 27inches. What is the length of the TV?

MATH
A 30 in.
B
32 in.
C 36 in.
D 39 in.
45 in.
27 in.
Answer:
C) 36 inches
Step-by-step explanation:
Let the diagonal be the hypotenuse and use Pythagoras' Theorem:
[tex]a^2+27^2=45^2\\a^2+729=2025\\a^2=1296\\a=36[/tex]
So, the length of the TV was 36 inches.
