Answer:
Inequality: 7.5x – 100 > 79.86 + 5.8x
Solution: x>106
The company must sell at least 106 items to make a profit.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
Revenue: 7.5x – 100
Costs: 79.86 + 5.8x
To make a profit, a company’s revenue must be greater than its operating costs.
So:
7.5x – 100 > 79.86 + 5.8x
Solving for x (number of items sold)
7.5x-5.8x>79.86+100
1.7x >179.86
x>179.86/1.7
x> 105.8
x>106
The company must sell at least 106 items to make a profit.
Feel free to ask for more if needed or if you did not understand something.
Answer:
first one : 7.5x -100 > 79.86 + 5.8x
second one : x > 105.8
last one : 106

Who is taking in more calories if the small bag of snickers are the exact same size: A person in a group where 5 people are sharing 3 small bags of snickers or a person in a group where 7 people are sharing 2 small bags of snickers
Answer:
A person in a group where 5 people are sharing 3 small bags of snickers
Step-by-step explanation:
Let the number of calories in one bag of snickers =x
Number of calories in 3 small bags of snickers =3x
If 5 people share 3 small bags of snickers, 1 person's share [tex]=\dfrac{3x}{5}[/tex]Number of calories in 2 small bags of snickers =2x
If 7 people share 2 small bags of snickers, 1 person's share [tex]=\dfrac{2x}{7}[/tex]We then compare the two.
Let x=1
[tex]\dfrac{3}{5}=0.6$ calories per person\\\dfrac{2}{7}=0.29$ calories per person[/tex]
Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.

a motor racing has a length of 5 5/6 a straight section of a circuit has a length 1 1/4 miles what fraction of the circuit is the straight section ? give your answer in the simplest form
Answer:
[tex]Fraction = \frac{3}{14}[/tex]
Step-by-step explanation:
Given:
[tex]Total\ Length = 5\frac{5}{6}[/tex]
[tex]Straight\ Section = 1\frac{1}{4}[/tex]
Required:
Fraction of the circuit that is straight section
To solve this, we simply divide the length of the straight section by the total length of the circuit;
This is done as follows;
[tex]Fraction = 1\frac{1}{4} / 5\frac{5}{6}[/tex]
Convert both fractions to improper fractions
[tex]Fraction = \frac{5}{4} / \frac{35}{6}[/tex]
Change division sign (/) to multiplication (*)
[tex]Fraction = \frac{5}{4} * \frac{6}{35}[/tex]
Combine to form a single fraction
[tex]Fraction = \frac{5*6}{4*35}[/tex]
[tex]Fraction = \frac{30}{140}[/tex]
Divide numerator and denominator by 10
[tex]Fraction = \frac{3}{14}[/tex]
Hence, the fraction of the straight section is; [tex]Fraction = \frac{3}{14}[/tex]

What is the area of it?
Answer:
12 ft²
Step-by-step explanation:
The figure is composed of 2 triangles.
The area (A) of a triangle is calculated as
A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )
A of upper triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 2 × 3 = 6 ft²
A of lower triangle = [tex]\frac{1}{2}[/tex] × 4 × 3 = 2 × 3 = 6 ft²
Thus
area of figure = 6 + 6 = 12 ft²

Pleas I don’t know the answer to this question
Answer:
41
Step-by-step explanation:
Think about this as a triangle: the measurements given are the legs and the diagonal wanted is the hypotenuse. We can assume this is a right triangle so you could use trig if you wanted but can also use the Pythagorean theorem which is way easier in this case.
[tex] {a}^{2} + {b}^{2} = {c}^{2} [/tex]
[tex] {35.7}^{2} + {20.1}^{2} = {c}^{2} [/tex]
Rounding to the nearest whole number:
[tex]c = 41[/tex]
Help me plzzzz plzzz
Answer:
1st Choice
Step-by-step explanation:
The fastest way to do this is by thinking of translations. If you are trying to move it left or right, it will be inside the cube root. If you want to move it vertically, it will be outside the root. In the graph, the child function is moving from the parent function to the right. This means we can eliminate choices C and D. We are left with A and B. A is the right choice because you take the negative of the direction you want to move in. Thus, you have your answer.

PLEASE ANSWER ASAP AND PROVIDE EXPLANATION! A copy machine is set up to enlarge an original in the ratio 2:3. What is this enlargement in percent?
Answer:
50%
Step-by-step explanation:
Enlarging it in the ratio 2:3 means dividing it by 2 and multiplying it by 3.
Lest's pretend the original size was 100 in. 100/2x3=150
So in this case we enlarged it by 50 in. which is 50% of 100.
So, the enlargement as a percentage is 50%
Answer:
50% more
3-2=1
1/2=0.5
0.5=50%
You can also double check by adding half of two and checking if it is 3
2 x 0.5 = 1
2 + 1 = 3
50% increase

On Wednesday, a local hamburger shop sold a combined total of 372 hamburgers and cheeseburgers. The number of cheeseburgers sold was three times the number of hamburgers sold. How many hamburgers were sold on Wednesday?
Answer:
93 hamburgers
Step-by-step explanation:
let cheeseburgers=c
let hamburgers=h
c=3h
c+h=372
Substitute c for 3h
3h+h=372
4h=372
h=93
c=h*3=93*3=279
279 cheeseburgers 93 hamburgers
3(x+1)=2(x-1) solve for x
Answer:
x = -5
Step-by-step explanation:
3(1 + x) = 2(x + -1)
(1 * 3 + x * 3) = 2(x + -1)
(3 + 3x) = 2(x + -1)
Reorder the terms:
3 + 3x = 2(-1 + x)
3 + 3x = (-1 * 2 + x * 2)
3 + 3x = (-2 + 2x)
Solving :the equation
3 + 3x = -2 + 2x
add '-2x' to each side of the equation.
3 + 3x + -2x = -2 + 2x + -2x
Combine like terms: 3x + -2x = x
3 + x = -2 + 2x + -2x
combine like terms: 2x + -2x = 0
3 + x = -2 + 0
3 + x = -2
Add '-3' to each side of the equation.
3 + -3 + x = -2 + -3
Combine like terms: 3 + -3 = 0
0 + x = -2 + -3
x = -2 + -3
Combine like terms: -2 + -3 = -5
x = -5
divide each side by '1'.
x = -5

A ticket for a seat at a village parish play costs £3.95 There are 17 rows of seats. There are 29 seats in each row. The village parish will sell all the tickets. Work out an estimate for the total money the village parish will get. Explanation:
Answer:
Total money earned = £1,947.35
Step-by-step explanation:
Given:
Per ticket cost = £3.95
Number of rows = 17
Number of seats in each row = 29 seats
Find:
Total money earned.
Computation:
Total number of seats = Number of rows × Number of seats in each row
Total number of seats = 17 × 29
Total number of seats = 493 seats
Total money earned = Total number of seats × Per ticket cost
Total money earned = 493 × £3.95
Total money earned = £1,947.35

By definition, empirical probability is equal to:
O A.
Total number of trials/
Total number of successful trials
O B.
Number of trials/
Total number of trials
C.Number of successful trials/
Total number of trials
D.Number of favorable outcomes/
Total number of possible outcomes
Answer:
C.) Number of successful trials / Total number of trials
Step-by-step explanation:
The empirical probability of an event 'E' is defined as :
(Number of successful occurrences of event 'E' / Total number of trials)
The empirical probability requires that an experiment of a chosen number of trials be performed. The ratio of the number of success to the total number of trials is used to estimate the empirical probability of such event.
P(Empirical) = (Number of successful trials / Total number of trials)
This is different from the use of sample space in the evaluation of theoretical probability whereby all possible occurences is used to estimate the probable outcome of an event.
P(theoretical) = (number of required outcomes / total number of possible outcomes)

Step-by-step explanation:
A sporting goods store receives a shipment of 124 golf bags. The shipment includes two types of bags, full-size and collapsible. The full-size bags cost $38.50 each. The collapsible bags cost $22.50 each. The bill for the shipment was $3430. How much of each type of golf bag should be in the shipment? Show all work and verify your answer (prove that your answer is correct)
The sporting goods store receives the shipment of 124 golf bags in total.
Let us assume that the number of full-sized bags = X
Then the number of collapsible golf bags = 124 - X
Cost of each full sized bags = $38.50
Cost of each collapsible bags = $22.50
Total cost of the 124 bags received by the sporting goods store = $3430
Then
(38.50)X + (124 - X)22.50 = 3430
(38.50X - 22.50X) + 2790 = 3430
16X = 3430 - 2790
16X = 640
X = 640/16
= 40
So the number of full-sized golf bags received = 40
Then the number of collapsible golf bags received = 124 - 40
= 84
