Answer:
8x10^5
Step-by-step explanation:
Answer:
Using the knowledge that a x 10ⁿ = a followed by ⁿ zeroes (eg: 5 x 10³ = 5,000)
We know that:
4 x 10⁴ is equal to 40,000
2 x 10¹ is equal to 20
Using the knowledge that (a)(b) = a x b, our next step would be to multiply those figures together.
40,000 x 20. We can do this without a calculator by counting how many zeroes are there.
Since there’s 5 zeroes, we know our answer will have 5 zeroes and we can take those 5 zeroes out of our equation:
So instead of 40000 x 20, we have 4 x 2 which we know is 8. Using our knowledge that our answer will have 5 zeroes, 40000 x 20 is equal to 800,000 (8 followed by 5 zeroes).
Our final step is to put that number into scientific notation. We know that 800,000 contains 5 zeroes, therefore 800,000 in scientific notation is:
8 x 10⁵
The correct answer would be D.
I hope this made sense and helps you and if you have any questions or think that I’ve made a mistake please let me know!

Miranda has been offered two jobs. The pay at job A would be $750 per month plus 15% of the value of the merchandise she sells. Job B offers $675 per month plus 20% of the value of the merchandise she sells. What value of merchandise must she sell in order to make more money at job B than job A? Which of the following best represents this situation?
A. 750 + 0.15x = 675 + 0.20x
B. 750 + 0.20x = 675 + 0.15x
C. 750 + 0.15x > 675 + 0.20x
D. 750 + 0.15x < 675 + 0.20x
Answers
Answer:
x - would be the total value of merchandise sold
y - would be her take home pay would be
Job A: y = 0.15x + 750
Job B: y = 0.20x + 675
We want to know when job B's pay will be larger than job A's pay. So set the expression for job B larger than job A, solve for x
0.20x + 675 > 0.15x + 750
0.20x - 0.15x > 750 - 675
0.05x > 75
x > 75/0.05
x > 1500
Miranda must sell more than $1500 worth of merchandise to have

Answers
2•2x=4x
2•-8= -16
So now 4x-16
Now divide both sides by 4
4x/4=x
-16/4=-4
X=-4
Answer:
x < 8
Step-by-step explanation:
This is a special case, so at the end of the equation we'll flip the sign.
Distribute:
2 * 2x = 4x
2 * -8 = -16
4x - 16
4 * 3x = 12x
4 * -12 = -48
12x - 48
4x - 16 > 12x - 48.
Subtract 12 from both sides.
12 - 12 = 0
4x - 12x = -8x
-8x - 16 > -48
The additive inverse of subtraction is addition so do -16 + -48, which equals -64
-8x/-8 = x
-64/-8 = 8
Now this is where we flip our sign so here we go :)
x < 8
There.
Hope this helped and sorry if I'm wrong.

10% of the world’s population is left-handed. If there are 7,400,000,000 people on the planet, how many are left-handed and how many are right handed?
Answers
Answer:
740,000,000 people are left handed and around 666,000,000 people are right handed.
Step-by-step explanation:
I think this is the correct answer. Hope I helped!
6,660,000,000 right handed people
Steps:
10% is equal to 0.1
7,400,000,000 multiplied by 0.1
Equals 740,000,000 left handed
Total amount of people subtract left handed people equal right handed people
7,400,000,000 - 740,000,000 = 6,660,000,000 right handed people

The student council has decided to have a raffle at the carnival. They came up with a table to show the relationship between the number of tickets bought and the number of raffle entries. Explain why it could be helpful for the student council to determine an equation to represent this data.
Answers
Answer:
An equation is helpful in other to make predictions about the number of raffle entries for a given number of tickets purchased.
Representing data such the one described above as an equation is helpful in other to obtain a mathematical model to make projection about the number of raffle entries possible for any number of ticket purchased.
For instance :
If the number of tickets bought = x
Number of raffle entries = y
A linear equation model to predict the number of raffle entries, y can be obtained. Hence, we can have a model in the form :
y = bx + c
Where, b = slope or rate of change
c = intercept.
An equation is helpful in other to make predictions about the number of raffle entries for a given number of tickets purchased.
Step-by-step explanation:
Answer:Write an equation to find the number of each type of ticket they should sell.Let "x" be # of adult tickets; Let "y" be # of student tickets: Value Equation: 5x+3y=450-------------------------- b. Graph your equation.y = (-5/3)x+150
c. Use your graph to find two different combinations of tickets sold.I'll leave that to you.
And so looking at a table only gives you a small number of data points, whereas an equation can be used to find any data point.
