When a bakery opened this morning, the ratio of the number of pineapple muffins to the number of mango muffins was 3 : 2. After 244 pineapple muffins were sold, the ratio of the number of pineapple muffins to the number of mango muffins changed to 3 : 5. How many pineapple muffins were there when the bakery opened this morning?
Answer:
(x+244)/y=3/2
x/y=3/5
y=5x/3
(x+244)/(x5/3)=3/2
x+244=3/2 . 5x/3
x+244=15x/6
6(x+244)=15x
6x+1464=15x
1464=15x-6x
1464=9x
x=1464/9
x≈ 162
mm=162*5/3=270
162:270 = 3:5
pm before = 270*3/2=405
405:270 = 3:2

You start at (8, 3). You move down 1 unit. Where do you end?
Answer:
(8, 2)Step-by-step explanation:
Initial point is: (x, y) = (8, 3)
When you move up or down, you change the y-coordinateWhen you move left or right you change the x-coordinateMove down 1 unit:
(x, y) → (x, y - 1)The new point is:
(8, 2)You have a triangle with one 70 degree angle and one 40 degree angle. What is the measure of the other angle? A) 40 degrees B) 70 degrees C) 60 degrees D) 180 degrees
Answer:
B) 70 degrees
Step-by-step explanation:
The sum of angles in a triangle = 180 degrees
We are given 2 angles in the triangle = 70° and 40°
The measure of the third angle is
180° = 70° + 40° + 3rd Angle
3rd Angle = 180° - ( 70° + 40°)
= 180° - 110°
= 70°
The measure of the other angle is 70°
Option B is the correct option.

John has 8 different flags that he wants to hang on the wall. How many different ways can the flags be arranged in a row?
Answer:
40,320 different ways
Step-by-step explanation:
Here, we want to arrange 8 flags in a row
In the row, there will be 8 places
The first place has 8 flags to be chosen from
The second place has 7 and like that
So mathematically, the number of ways that we can arrange the flags is 8 factorial ways
We have this as:
8! = 40,320 different ways

Given:
The four table of values.
To find:
The table whose linear function has slope 2.
Solution:
Slope formula:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Consider any two points from each table and find the slope for each table.
For table 1, the two points are (2,1) and (6,-1). So, the slope of the linear function is:
[tex]m=\dfrac{-1-1}{6-2}[/tex]
[tex]m=\dfrac{-2}{4}[/tex]
[tex]m=\dfrac{-1}{2}[/tex]
For table 2, the two points are (0,8) and (2,4). So, the slope of the linear function is:
[tex]m=\dfrac{4-8}{2-0}[/tex]
[tex]m=\dfrac{-4}{2}[/tex]
[tex]m=2[/tex]
For table 3, the two points are (-4,4) and (-2,5). So, the slope of the linear function is:
[tex]m=\dfrac{5-4}{-2-(-4)}[/tex]
[tex]m=\dfrac{1}{-2+4}[/tex]
[tex]m=\dfrac{1}{2}[/tex]
For table 4, the two points are (-2,0) and (0,4). So, the slope of the linear function is:
[tex]m=\dfrac{4-0}{0-(-2)}[/tex]
[tex]m=\dfrac{4}{2}[/tex]
[tex]m=2[/tex]
Table 4 is the only table that represents a linear function whose slope is 2.
Therefore, the correct option is 4, Table 4.
A company sells widgets. The amount of profit, y, made by the company, is related to the selling price of each widget, x, by the given equation. Using this equation, find out what price the widgets should be sold for, to the nearest cent, for the company to make the maximum profit.
y=-x^2+73x-520
y=−x
2
+73x−520
Answer:
36.5
Step-by-step explanation:
y= -x²+73x-520
which can be represented as ax²+bx+c
a= -1, b= 73, c = -520
for maximum value of y,
the formula is
c - (b² / 4a)
= -520 - (73² / 4×(-1))
= -520 - (5329 / -4)
= -520 + 1332.25
= 812.25
Solving for x,
812.25 = -x²+73x-520
or, x²-73x+ 1332.25 = 0
Solving,
x= 36.5
The body of a dump truck is raised to empty a load of sand. How high is the 14-foot-long body from the frame when it is tipped upward by a 60° angle?
Answer:
12.12 feets
Step-by-step explanation:
Based on the attached diagram, we can apply trigonometric rule to obtain h :
Sinθ = opposite / hypotenus
Opposite = h
Hypotenus = 14
Sin 60 = h / 14
0.8660254 = h / 14
h = 0.8660254 * 14
Height, h = 12.12 feets

Answer:
X=6
B=126
Step-by-step explanation:
8x+78°=2x+114°
8x-2x=114-78
6x=36
x=6
B=2(6)+114
B=12+114
B=126°
Note angle A and B are alternate angles and thus are equal
Answer:
since X=6 ,
2×6+114= 126 .

Tyler owned the librarian late fees he had to pay a 3% fee on the cost of the books, which was $35.62. What was he charged for a late fee?
Answer:
$1.07 for the late fees.
Step-by-step explanation:
You can find the fee for this price by finding 3% of the $35.62 (total cost of the books). You can find this number by multiplying (35.62*.03).
35.62*.03
1.0686
Round up because you cannot have part of a cent.
$1.07 for the late fees.
Determine the correlation coefficient (r) for the linear relationship below.
Answer:
X Values
∑ = 53.5
Mean = 10.7
∑(X - Mx)2 = SSx = 151.086
Y Values
∑ = 6.9
Mean = 1.38
∑(Y - My)2 = SSy = 3.788
X and Y Combined
N = 5
∑(X - Mx)(Y - My) = 23.711
R Calculation
r = ∑((X - My)(Y - Mx)) / √((SSx)(SSy))
r = 23.711 / √((151.086)(3.788)) = 0.9911
So r= 0.9911 or 99.11%

Find the slope of the line that passes through the following points: `\left(\frac{2}{5},\frac{2}{3}\right)\ \ \left(-\frac{4}{9},\frac{3}{5}\right)` Show the work/explain!
Answer:
3/50
Step-by-step explanation:
Slope m = y2-y1/x2-x1
From the coordinate
x1 = 2/5, y1 = 2/3, x2 = -4/9 and y2 = 3/5
Substitute;
m = (3/5 - 2/3)/-4/9-2/3
m = (9-10/15)/(-4-6/9)
m = -1/15/-10/9
m = -1/15 * -9/10
m = 9/150
m = 3/50
Hence the slope of the line passing through the points is 3/50
