A manager samples the receipts of every fifth person who goes through the line. Out of 50 people, 4 had a mispriced item. If 1,400 people go to this store each day, how many people would you expect to have a mispriced item?
Answer:
112 people
Step-by-step explanation:
[tex]\frac{4}{50}[/tex] = [tex]\frac{x}{1400}[/tex] write the proportion where x is the number of people with a missplaced time
50x = 5600 cross multipy
x = 112 divide both sides by 50
The complement of the angle is 1/2 of the measure of the angle. Find the measure of the angle.
Group of answer choices
1.180°
2.90°
3.60°
4.30°
Answer:
choice 2) x = 60°
Step-by-step explanation:
the complement of an angle is an angle that when added to the original angle = 90°
so:
x + 0.5x = 90°
1.5x = 90°
x = 90/1.5 = 60°

I'm trying to solve for X and X+Y. Please help me!
Answer:
From 12 o'clock position clockwise:
-12
-1
11
12
Step-by-step explanation:
y = -1 (given).
x + y = 11
Plug in -1 for y in the equation (given):
x + (-1) = 11
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 1 to both sides of the equation:
x - 1 (+1) = 11 (+1)
x = 11 + 1
x = 12
x + y = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables:
12 + (-1) = 12 - 1 = 11
xy = ?
x = 12
y = -1
Plug in the corresponding numbers to the corresponding variables. Note that when you multiply a negative and a positive number, your answer will be negative:
12 * -1 = -12

The length of a rectangle is 3 times its width. If the length were increased by 2 inches and the width by 1 inch, the new perimeter would be 62 inches. What is the width and length of the rectangle? If w represents the width of the rectangle, then which equation could be used to solve for w?
2(4 w + 3) = 62
( w + 1)(3w + 2)=62
2(3 w + 3) = 62
Answer:
2(4 w + 3) = 62
width =7 length = 21
Step-by-step explanation:
For the perimeter you need :
2 times the width and 2 times the length (length =3w)
so
2(w+1) + 2 (3w+2) =
2w+2 + 6w+4 =
8w +6
you can factor this by:
2(4w+3)
8w +6= 62
8W = 56
w= 7 l= 21
2(7+1) + 2 (21+2)
16 + 46 = 62

The vertices of a figure are given. Find the coordinates of the figure after the transformations given. A(−5,3),B(−2,3),C(−2,1),D(−5,1)Reflect in the y-axis. Then dilate with respect to the origin using a scale factor of 2. (help please))!!!
Answer:
Reflection: A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
Dialation: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)
Step-by-step explanation:
A(−5,3),B(−2,3),C(−2,1),D(−5,1)
To reflect over the y-axis you change the value of x. In this case all of the values for x are negative. You turn them all into a positive.:
A' (5, 3)
B' (2, 3)
C' (2, 1)
D' (5, 1)
To dialate by a scale factor of 2 you multiple everything by 2 and you should get: A"(10, 6)
B" (4, 6)
C" (4, 2)
D" (10, 2)
