a. Okay, so you multiply the 4.7 and 2.9 together, and then add the exponents
13.63 * 10^10
But we are not done. There can only be one digit in front of the decimal point. So, you move the 13.63 back one place so 1.363. But we have to do this to both sides, so the answer is 1.363 * 10^11.
b. Now you divide the 5.8 and 2, and subtract the exponents.
2.9 * 10^-5
The negative exponent is fine in this case if you were wondering.
c. Expand the scientific notation to 1500, then add the 2491 and then put that in scientific notation is what I would do. You can also express 2491 in scientific notation and add them. Either way you will get 3.991 * 10^3
d. Same thing here except with subtraction. The answer is 6.5 * 10^-4.
This was a little long, sorry. Let me know if you need further explanation. I hope this helps.

Answers
Let c represent amount of commission and s represent amount of sales.
We have been given that Lee sells electronics. He earns a 5% commission on each sale he makes.
A. We are asked to find the constant of proportionality.
First of all, we will write our given equation as direct proportion. We know that two proportional quantities are in form [tex]y=kx[/tex], where y is directly proportional to x and k represents constant of proportionality.
We can represent our given information in an equation as:
[tex]c=\frac{5}{100}s[/tex]
[tex]c=0.05s[/tex]
Therefore, constant of proportionality is [tex]0.05[/tex].
B. To find amount of electronics sold by Lee, we will substitute [tex]c=100[/tex] in our equation an solve for s as:
[tex]100=0.05s[/tex]
[tex]\frac{100}{0.05}=\frac{0.05s}{0.05}[/tex]
[tex]2000=s[/tex]
Therefore, Lee must sell $2000 of electronics to make $100 commission.

Two sides of a triangle are as follows: 2 centimeters and 5 centimeters. Describe the possible lengths of the third side
Answers
Answer:
3cm < Third side < 7cm
Thus third side can take any value between 3cm and 7 cm
(note: excluding 3 cm and 7 cm)
If the value are integral then possible values of third side are
4cm, 5cm,6cm
Step-by-step explanation:
This question can be solved using given by Triangle Inequality Theorem Given below.
Sum of two sides is always greater than value of third sideDifference of two sides is always less than value of third sideGiven two sides are 2cm, 5cm
Sum of two sides = (2+5)cm = 7 cm
Difference of two sides = (5-2) = 3 cm
Let the third side be X
thus according to Triangle Inequality Theorem
X < Sum of two sides of given triangle
X < 7cm -----1
X > Difference of two sides
X > 3cm ----1
combining expression 1 and 2 we have
3cm < X < 7cm
Thus third side can take any value between 3cm and 7 cm
(note: excluding 3 cm and 7 cm)
If the value are integral then possible values are
4c, 5cm,6c

Step-by-step explanation:
In the picture attached, the missing table is shown.
At x-intercept, f(x) = 0, that is, if the value of the function is zero, the function intersects x-axis.
It can be seen at the picture, that f(x) = 0 when x = 2, then the point is (2, 0)
The following box plot shows points awarded to dance teams that competed at a recent competition:
Which dot plot best represents the box plot data?
Answers
Answer:
C
Step-by-step explanation:
In the box plot we can see that
minimum points awarded: 0maximum points awarded: 100then, options B and D are incorrect
The median in the box plot is 70. In option A, the median is 95, and in option C, the median is 70.
In option C, also, Q1 is located at 50 (like in the box plot), and Q3 is located at 95 (like in the box plot)
The dot plot that best represents the box plot data is: C.
The minimum, maximum, and median value of a a data set can easily be determined when the data points are plotted on a box plot or dot plot.
Thus, for the box plot, we have the following:
Minimum = 0Maximum = 100Median = 70Find the dot plot that has the above values as same with the given box plot:
The dot plot in option C has minimum of 0, maximum of 100, and median of 70, therefore, the dot plot that best represents the box plot data is: C.

what is the question for this?
consider the following three equations:
linear: y=20x+300
Quadratic: y=5x^2
Exponential: y=10(1.4)^x
use the equations to answer the following questions. Support your answers with work.
1. At an x-value of 11, which equation has the largest y-value?
2. what is the smallest integer value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions?
Answers
Answer:
1.
y = 20(11) + 300 = 520
y = 5(11)(11) = 605
y = 10(1.4)^11 = 404.96
hence the quadratic formula - y = 5x^2 has the largest y-value
2.
y = 20 (14) + 300 = 580
y = 5 (14) (14) = 980
y = 10(1.4)^ 14 = 1111.20 > this is greater than both equations above
14 is the smallest value of x for which the value of the exponential equation is greater than the values of both the linear and quadratic functions
Step-by-step explanation:
Answer:
1. Quadratic
2. x = 14
Step-by-step explanation:
1. At x = 11
linear: y=20(11) + 300 = 520
Quadratic: y=5× 11² = 605
Exponential: y=10(1.4)¹¹ = 404.956517
2. 10(1.4^x) > 20x + 300
1.4^x > 2x + 30
1.4^x - 2x - 30 > 0
Using trial method:
x > 11
10(1.4^x) > 5x²
1.4^x - 0.5x² > 0
Using trail method:
x > 13

Jen earns $35,650 a year working for an electronics supplier. She is single with no
dependents and pays $1,749.80 in state income tax each year. What is the state's tax
rate?
Answers
Answer: 5% approximately
Step-by-step explanation:
Jen earns $35,650 a year working for an electronics supplier and pays $1,749.80 in state income tax each year. To calculate the income tax rate, we divide the amount paid as tax by her annual income and then multiply by 100. This will be:
= 1749.80/35650 × 100
= 4.91%
= 5% approximately
The state's tax rate is 5%.
