2. Which two equations are represented in the following graph?
Answer:
C. y=x+4 and y=3x+2
Step-by-step explanation:
The value of k lies between 2.2 and 2.3.
Select all possible values of k.
Answer:
Its easy... 5 and 5.04!
Step-by-step explanation:
You have to look at it properly. It says "The value of SQUARE ROOTED K."
So all you have to do is square root them and whatever is in between 2.2 and 2.3 is ur answer. Ur answer 5 and 5.04.
The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Given that √k falls between 2.2 and 2.3
For k = 1.49, √1.49 = 1.22 which is not between 2.2 and 2.3
For k = 4.8, √4.8 = 2.19 which is not between 2.2 and 2.3
For k = 5, √5 = 2.2 3which is between 2.2 and 2.3
For k = 5.04, √5,04 = 2.23 which is between 2.2 and 2.3
For k = 5.3, √5.3 = 2.302 which is not between 2.2 and 2.3
For k = 6, √6 which is not between 2.2 and 2.3
The values of √k that lies between 2.2 and 2.3 is 5 and 5.04.

We want to compare two linear equations and answer some things in regards to these.
A) Your line should be steeper.B) your slope is $20 per week, your friend slope is $15 per week.C) Your friend wins $5 less than you per week.D) You must save for 9 weeks, your friend for 11 weeks.So we have two sets of data:
you: (2 weeks, $40), (5 weeks, $100)friend: (4 weeks, $60), (8 weeks, $120)A) First we want to compare the steepness of the lines, it will represent how much money you and your friend gets per week, a more steep line means a larger weekly income.
By the given points, you can see that you have an increase of $60 in 3 weeks, while your friend has an increase of $60 in 4 weeks, thus, your line should be steeper.
B) We know that for a line that passes through points (x₁, y₁) and (x₂, y₂) the slope is given by:
[tex]s = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, for you, the slope is:
[tex]s_y = \frac{\$100 - \$40}{5 weeks - 2 weeks} = \$20\ per \ week[/tex]
For your friend the slope is:
[tex]s_f = \frac{\$120 - \$60}{8 weeks - 4 weeks} = \$15 \ per \ week[/tex]
C) Your friend saves $5 less than you per week.
D) You, by week 5, have $100
So you need to save another $65
And you save $20 per week, so we need to solve:
$20*x = $65
x = $65/$20 = 3.25
Rounding to the next whole number, x = 4
And this is 4 weeks after the 5th week, so you need to save for a total of 9 weeks.
For your friend, he has $120 at the 8th week, then he must save another $45, and he saves $15 per week, so we need to solve:
$15*x = $45
x = $45/$15 = 3
He must save for another 3 weeks, for a total of 11 weeks.

The Martin family purchases a new home at a cost of $240,000. They finance the home for 30 years at 6% interest, compounded continuously
How much will the Martins pay for the house, including interest
Given:
Principal value = $240,000
Rate of interest = 6% compounded continuously.
Time = 30 years
To find:

Dalton when to high school at 11 yrs and 3 months he left high school at 18 yrs and 2 months old how long did Dalton spend in high School
Answer:
Dalton spent 6 years and 11 months in high school.
Step-by-step explanation:
Dalton were in high school at the age = 11 years and 3 months He left high school at the age = 18 years and 2 months
Time spent by Dalton in high school = 18 years 2 months - 11 years and 3 months
= (18 - 11) years and (2 - 3) months
= 7 years - 1 month
= (6 + 1) years - 1 month
= 6 years + 1 year - 1 month
= 6years + 12 months - 1 month
= 6 years + 11 months

A store has 2000 grocery bags to give away as part of its grand opening. The store is handing out 150 bags per hour. In how many hours will the store have 950 bags remaining? Write an equation that represents this scenario. Then solve.
Answer:
13.3 repeated
Step-by-step explanation:
You need to take 2000 and divide it by 15. Then your answer will come.
*13.3*
Answer:
7 hrs
Step-by-step explanation:
2000 grocery bags
Let x be the number of hours
If they're handing out 150 bags per hour, then 150x would be the amount given out in x hrs.
Since we want to get 950 bags left over a certain number of hrs, make this equation and solve:
950=2000-150x
150x=1050
x=7

A large emerald with a mass of 982.7 grams was recently discovered in a mine. If the density of the emerald is 2.76 grams over centimeters cubed, what is the volume? Round to the nearest hundredth when necessary and only enter numerical values, which can include a decimal point.
Answer:
356.05 cm³
Step-by-step explanation:
We are looking for the volume. The formula is density = mass / volume.
If we plug in our numbers, our formula would be 2.76 = 982.7 / V.
Multiply both sides by V and your formula would be (V) 2.76 = 982.7.
Divide both sides by 2.76 and you would get V = 356.05.
The volume of the given large emerald is required.
The volume of the given large emerald that was discovered in the mine was 356.05 cm³. The calculations to find this value is shown below.
Densitym = Mass of object = 982.7 grams
[tex]\rho[/tex] = Density of the material the object is made of = 2.76 grams over centimeters cubed
The relation between mass, volume and density is given by
[tex]V=\dfrac{m}{\rho}\\\Rightarrow V=\dfrac{982.7}{2.76}\\\Rightarrow V=356.05072\approx 356.05\ \text{cm}^3[/tex]

Determine the mean absolute deviation of the data.9, 7, 11, 10, 8
Answer:
1.2
Step-by-step explanation:
First, we need to find the mean of the data. We do this by adding all of the given numbers than dividing it by the number of numbers given. For example, we will add 9+7+11+10+8 which is 45. Since there are 5 given numbers, we are going to divide 45 by 5 which is 9. Now, we need to find the difference (subtraction) of all of the numbers in relation to 9. For example, for 9, we do 9-7 which is 2. Keep 2 in mind. Then we do 11-9 which is also 2. 10-9 is 1. 9-9 is 0. And finally, 9 minus 8 is also 1. Then, like what we did before, we need to find the mean of all of these differences. 2 plus 2 plus 1 plus 0 plus 1 is 6. Then, we divide 6 (our total of these differences) by 5 (the number of differences) 6 divided by 5 is 1.2 so there is your MAD and answer.
The mean absolute deviation of the given data is 1.2.
What is mean absolute deviation?The mean absolute deviation of a dataset is the average distance between each data point and the mean. It gives us an idea about the variability in a dataset.
Here's how to calculate the mean absolute deviation.
Data given: 9, 7, 11, 10, 8
Step 1: Calculate the mean.
[tex]mean = \frac{sum\ of\ observations}{number\ of\ observations} \\\\mean = \frac{9 + 7+11 + 10 + 8}{5}\\ \\mean =9[/tex]
Step 2: Calculate how far away each data point is from the mean using positive distances. These are called absolute deviations.
Data Distance from mean
9 |9 - 9| = 0
7 |7 - 9| = 2
11 |11 - 9| = 2
10 |10 - 9| = 1
8 |8 - 9| =1
Step 3: Add those deviations together.
Sum of deviations = 0 + 2 + 2 + 1 + 1 = 6
Step 4: Divide the sum by the number of data points.
Mean absolute deviation = [tex]\frac{sum\ of\ deviations}{number\ of\ observations}\\ \\[/tex] = [tex]\frac{6}{5} = 1.2[/tex]
