Answer:
15%Step-by-step explanation:
this week sold = $2,760
last week sold = $2,400
the difference from this week to last week = 2700-2400 = 360
that means it increased : 360 / 2400 = 0.15 (100%) = 15%
therefore, the increase of sale is 15%

Consider the equation y = 1.5x + 2. Find four pairs of x and y values that make
the equation true. Plot the points (x, y) on the coordinate plane.
Based on the graph, can this be a proportional relationship? Why or why not?
Answer:
1. (2,5),(1,3.5),(4,8),(6,11)
2. This is not a proportional relationship (explanation below)
Step-by-step explanation:
For the plotting, if you take some random x values and multiply by 1.5 and add 2 to them.
This can't be a proportional relationship. A proportional relationship means the x and y values' ratios have to stay the same. However, because 2 is added to 1.5x, the equation is not proportional.
The four x and y values that make the equation true are (0,2), (-1.333,0), (1,3.5), and (1,3.5).
What in mathematics is a proportionate relationship?When the ratios of two variables are equal, they form proportional relationships. Another way to think about them is that in a proportionate relationship, one variable is always equal to the constant value of the other.This constant is known as the "constant of proportionality." To find: The four sets of x and y values required to solve the equation. Put the (x, y) coordinates on a coordinate plane.Therefore,
We select several x and y values,
1) Take x=0,
y = 1.5(0) + 2 =2.
The point is (0,2).
2) Take y=0,
0 = 1.5x + 2
x = -2/1.5 = -1.333
The point is (-1.333,0).
3) Take x=1,
y = 1.5(1) + 2 = 3.5
The point is (1,3.5).
4) Take y=1,
1 = 1.5x +2
1.5x = -1
x = -1/1.5 = -0.666.
The point is (-0.666,1).
The four sets of x and y numbers that make the equation true are (0,2), (-1.333,0), (1,3.5), and (0,2).

Little Bear can eat all the honey in a jar in 10 minutes. If Papa Bear eats honey with him, they can eat all the honey in the jar in 6 minutes. How long would it take Papa Bear to eat the jar of honey alone?
Pls Help
Answer:
15
Step-by-step explanation:
little bear consumes 1/10 jar/min
in 6 minutes , little bear would consume 6 min * 1/10 jar/min = 6/10 jar = 0.6 jar
this means , that in those same 6 minutes papa bear needs to have eaten the remaining 0.4 jar also it takes 6 min/0.4 jar = 6*10/4 min/jar = 15 min/jar
The time taken for Papa Bear to eat the jar of honey alone is 15 minutes.
Based on the information given, the little bear will use 1/10 minutes.
In 6 minutes, the little bear will have eaten 0.6 jars
Therefore, the time taken for the papa bear will be:
= 6 minutes / (1 - 0.6)
= 6/0.4
= 15 minutes
Therefore, the correct option is 15 minutes per jar.

During the summer, the height of the water in a pool decreases by 4 inches each week. What is the change in height of the water over a six week period?
Height of water in a pool that decreases every week during summer = 4 inches
The change of the height of water in six weeks :-
[tex] = 6 \times 4[/tex]
[tex]\color{olive} =\color{hotpink} 24\color{olive} \: \: inches[/tex]
Therefore , the height of the water in the pool would have decreased by 24 inches in six weeks .

An atom is neutral. Its nucleus contains two protons and two neutrons. How
many electrons does the atom have?
Answer:
2 electrons
Step-by-step explanation:
An atom is neutral if it has no charge. That means the positive and negative charge balance each other out.
There are two protons, so that is a charge of +2. To make the charge 0, there needs to be a charge of -2. -2= 2 electrons.

The average smoker typically pays 15% higher life insurance costs than the average non-smoke. If the monthly cost to a non-smoker is $500 dollars per month, how much would the average smoker pay per month for the same life insurance policy?
Answer:
$600 for a smoker
Step-by-step explanation:
On average, smokers will typically pay 15-20% higher premiums than non-smokers with equivalent demographics and health conditions. If the monthly premium for a non-smoker is $500 per month, it will be upwards of $600 for a smoker. The health insurance companies face a double-edged sword when it comes to insuring smokers.

How do you write, 24.23 as a mixed number in simplest form?
Answer:
24 23/100
Step-by-step explanation:
I think this is the answer.
9514 1404 393
Answer:
24 23/100
Step-by-step explanation:
"Twenty-three hundredths," or 23/100, is a fraction that cannot be reduced. The mixed number version is ...
24 23/100
_____
Additional comment
You start with a denominator that corresponds to the place value of the least-significant digit. Here, that's hundredths, so the fraction you start with is some number of hundredths. Then you reduce the fraction if possible, by canceling all factors of 2 or 5 that you can.
Had it been 23.24, you would start with 23 24/100 and cancel a factor of 4 from numerator and denominator: 23 6/25.
you start hiking at an elevation that is 550 meters below sea level.you increase your elevation by 45 meters.what is the new elevation? write an addition and evaluate.

You are at -505 meters below sea level
Answer:
You are now 38 m below base camp.
Step-by-step explanation:
Consider the provided information.
You start hiking at an elevation that is 80 meters below base camp.
Now your initial location is 80 m below base camp, that can be represents as: -80
Now you increase your elevation by 42.
So you go up by 42.
In other words, you get the equation -80+42 = -38.
Since, a negative value is below the base camp, this means that you are now 38 m below base camp.
