Ben earns $72 per day and $6 for each delivery he makes. He wants to earn more than $155 in a day. What is the LEAST number of deliveries he must make to reach his goal?
Answer: the least number of deliveries that Ben must make is 14.
Step-by-step explanation: Given that Ben earns $9 per hour and $6 for each delivery he makes. He wants to earn more than $155 in an 8-hour workday.
We are to find the least number of deliveries he must make to reach his goal.
Let x be the least number of deliveries that Ben must make to reach his goal.
Then, according to the given information, we have
Thus, the least number of deliveries that Ben must make is 14.

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°

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)

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

BRAINLIEST OF CORRECT !! the side lengths of a triangle are 6, 8, and 12. is this a right angle?
Answer:
C
Step-by-step explanation:
answer:
C. no, because 6^2 + 8^2 [tex]\neq[/tex] 12^2
step-by-step explanation:
use the pythagorean theorem formula in order to solve thisthe formula: a^2 + b^2 = c^2now plug in the valuesa^2 + b^2 = c^2
6 = a8 = b12 = c6^2 + 8^2 = 12^2

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
I am loosing soo much of my points by doing this I was at 102 now I am at 40 please answer these correctly
Answer:
C
Step-by-step explanation:
If we know that x is greater than or equal to 4, then we should substitute 4 in place of x in each possible solution.
A 4 + 3 ≥ 1 True, it's greater, but it can't be equal to.
B 3(4) ≥ 1 It's greater once again, can't be equal to.
C 4 - 3 ≥ 1 If x can also be greater than 4, then it works both ways. Equal and greater than.

The figure can be composed of different shapes.
What shapes can the figure be decomposed into to find the area? What is the area?
A. one triangle and one square; 24 square feet
B. one triangle and one rectangle; 30 square feet
C. two triangles and one square; 36 square feet
D. two triangles and one rectangle; 42 square feet
The figure can be composed in to one triangle and one rectangle and the area is 30 square feet.
What is Area?Area of a two dimensional shape is the total region which is bounded by the object's shape.
Given is a figure.
We can divide the figure in to one triangle and one rectangle by drawing a vertical line.
Area of a rectangle = Length × Width
Here, length = 8 feet and width = 3 feet
Area of rectangle = 8 × 3 = 24 feet²
Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
Base = 12 - 8 = 4 feet and height = 3 feet
Area of triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 6 feet²
Total area = 24 feet² + 6 feet² = 30 feet²
Hence the area is 30 feet².
