The mass of Earth is about 6 x 10^24 kilograms. The mass of the moon is about
7 x 10^ 22 kilograms. The mass of Jupiter is about 2 times 10^27 kilograms.
About how many times as large is Earth's mass compared to the moon's mass? Justify your answer.
About how many times as large is Jupiter's mass compared to Earth's mass? Justify your answer.
Answer:
Earth is 85.71 times heavier than moonJupiter is 333.33 times heavier than EarthStep-by-step explanation:
Given
The mass of Earth is about 6 x 10^24 kilograms = eThe mass of the moon is about 7 x 10^ 22 kilograms = mThe mass of Jupiter is about 2 x 10^27 kilograms = jThe difference in mass
e/m = 6 x 10^24 / 7 x 10^ 22 = 600/7 = 85.71Earth is 85.71 times heavier than moon
j/e = 2 x 10^27 / 6 x 10^24 = 2000/6 = 333.33Jupiter is 333.33 times heavier than Earth

Jim received notice from his employer that the equation to calculate his salary was changing. Currently he makes $300 per week plus 4% commission on sales. The new equation will be $450 plus 2% commission on sales. Which equation shows the amount in sales he will need for his salary to be the same?
Answer:
Sales= $750Step-by-step explanation:
let sale be x
and his salary be y
y=300+0.4x----------1 the old equation
y=450+0.2x----------2 the new equation
for his salary to be the same
equation 1 and 2 must be equal hence
300+0.4x=450+0.2x
solving for x we have
300-450+0.4x-0.2x=0
-150+0.2x=0
0.2x=150
x=150/0.2
x=$750

Madison is starting her own sewing business. Madison thinks she will do a better job than her competitors, so she thinks she can charge $13.05 per hour. If she knows she will only be able to work 190 hours per month (that's 47.5 hours per week), how much money will she earn each month?
Answer:
$2479.5Step-by-step explanation:
In this problem we will estimate her monthly earnings
given that she earns $13.05 per hour
and also given that she works for 190 hours in a month
then in a month, her earnings will be
=$13.05*190
=$2479.5
alternatively,
per week she works 47.5hours
in a week she will earn 13.05*47.7= $622.485
4 weeks make a month
then after one month her earning will be
$622.485*4= $2479.5
How can I split 166 in half
You divide 166 by 2. The answer would be 83.
The value of splitting 166 in half gives two equal halves of 83 each.
When 'split' a number in half, dividing the number into two equal parts.
Here want to split the number 166 in half.
Perform a division operation by dividing 166 by 2.
Division is the opposite operation of multiplication.
When divide a number by 2, you are essentially finding the value of half of that number.
So, the calculation is as follows:
166 ÷ 2 = 83
This means that half of 166 is 83.
Divide the number 166 into two equal parts, each being 83.
If add both halves together, you get the original number back:
83 + 83 = 166
Therefore, dividing 166 by 2 allows to splitting it equally into two halves, each having a value of 83.

An emerald pendant was marked up 150% from an original cost of $488. Last Friday, Cameron bought the emerald pendant and paid an additional 5% in sale tax. What was his total cost?
Given parameters:
Mark up percentage = 150%
Original cost = $488
Sales tax = 5%
Unknown:
His total cost = ?
Solution:
Marking up a good is the amount a sell adds to a product which makes its selling price usually for a profit.
Since the emerald was marked up by 150%;
New cost = (1 + 1.5) x $488 = $1220
Now, the additional tax was 5%;
Tax = [tex]\frac{5}{100}[/tex] x 1220 = $61
So, the total cost = New cost + tax = $1220 + $61 = $1281
the equation y= 1.25x represents the cost (y) to buy (x) granola bars at the sack shop. the table shows the cost of granola bars at the sports field. which location sells granola bars for a lower price
Answer:
Its the snack shop because for each bar it is 1.25 each.
Step-by-step explanation:
Answer:
The answer is Snack Shop.
Step-by-step explanation:
The equation given us, y=1.25x means this store sells a bar of granola for $1.25.
However the other store sells there granola bar for $1.30.
1.25 is less than 1.30.
Choose the store that sells their granola bar for $1.25.

C) arm span and foot length are predicted to increase by about 0.186 cm.
What is linear regression?Linear regression analysis is used to predict the value of a variable based on the value of another variable. The variable you want to predict is called the dependent variable. The variable you are using to predict the other variable's value is called the independent variable.
Given, The arm span and foot length were measured (in centimeters) for each of the 19 students in a statistics class and displayed in the scatterplot.
let "FL" be the foot length and "AS" be the Arm span.
Slope = Δy/Δx = ΔFL/ΔAS
ΔFL/ΔAS = 0.186
ΔFL = ΔAS* 0.186
thus an increase in AS by 1 cm will lead to an increase in FL by 0.186cm
Therefore, the slope of the least-squares regression line means for each additional centimeter C) arm span, foot length is predicted to increase by about 0.186 cm.

Quadratic formula of -24x = 6x^2
Answer:
x = 4
Step-by-step explanation:
Well, while this is not a full quadratic equation, this can still be worked with, so let's get started.
Taking [tex]-24x=6x^2[/tex], we can simplify this just to make it a bit more professional, to say [tex]6x^2=-24x[/tex] (We can do this because of the Symmetric Property of Equality, which states that a=b then b=a).
Now, we can really start by dividing both sides by 6, to get [tex]x^{2} =-4x[/tex], and then divide both sides by x to get [tex]x=4[/tex].
So, the answer of this quadratic equation is x = 4.
