James types 90 words in 2 minutes. At this rate, how many words can James type in 15 minutes?
Answer:
675 words
Step-by-step explanation:
If James can types 90 words in 2 minutes, we can assume that he can type 45 words per minute. If we multiply 45 words per minute by 15 minutes, we get 675.

Answer:
The total least sale amount is $5,000,000
Step-by-step explanation:
Given as :
The base salary amount of Carmen = $125,000
The commission percentage on total sale = 4%
The performance bonus amount = $25,000
The total compensation amount last year = $350,000
Let The total sale amount = $x
According to question
Total compensation amount last year = base salary amount + percentage on total sale + performance bonus amount
I.e $350,000 = $125,000 + 4% of x + $25,000
Or, $350,000 = $150,000 + 4% of x
Or, 4% of x = $350,000 - $150,000
Or, 4% of x = $200,000
Or, × x = $200,000
Or, x =
∴ x = $5,000,000
So, The total sale amount = x = $5,000,000
Hence, The total least sale amount is $5,000,000 Answer

Heather deposits $7000 into an account that pays simple interest at a rate of 2% per year. How much interest will she be paid in the first 3 years?
Answer:
year after 3 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $7000.00.
r is the interest rate, 2% per year, or in decimal form, 2/100=0.02.
t is the time involved, 3....year(s) time periods.
So, t is 3....year time periods.
To find the simple interest, we multiply 7000 × 0.02 × 3 to get that:
The interest is: $420.00
Usually now, the interest is added onto the principal to figure some new amount after 3 year(s),
or 7000.00 + 420.00 = 7420.00. For example:
If you borrowed the $7000.00, you would now owe $7420.00
If you loaned someone $7000.00, you would now be due $7420.00
If owned something, like a $7000.00 bond, it would be worth $7420.00 now.
Find the area of the circle with a circumference of 18.84 miles. Use 3.14 for π.
Answer:
Area = 28.25[tex]mi^{2}[/tex]
Step-by-step explanation:
Circumference formula:
C = πd
Plug in your data:
18.84mm = 3.14(d)
Divide by 3.14 to isolate for x.
18.84mm / 3.14 = d
d = 6mm
By using double inequality describe all the numbers that are:
a) greater than (−8) but less than (−2)
b) less than 0, but greater than (−5)
c) greater than (−3), but less than 3
Step-by-step explanation:
-8 < x < -2
-5 < x < 0
-3 < x < 3
"greater than" and "less than" is not inclusive of the number written. So
a) -7,-6,-5,-4,-3
b) -4,-3,-2,-1
c) -2,-1,0,1,2
The question should have specified "integers" btw. "All" numbers is impossible to list out since you can have 1.999999999999 but never quite 2

Sarah’s neighbor offers to pay her $5 for every shark tooth she finds on the beach. After collecting only three shark’s teeth, Sarah decides to share the opportunity with her friend John. Sarah can find shark teeth twice as fast as John, but she can earn even more money with his help.
Sarah can use the expression 5(2j + 3 + j) to represent the amount of money she can earn.
Part 1: Writing Expressions
Write an expression that looks like Sarah’s expression: 5(2j + 3 + j). Replace the coefficients so that your expression is not equivalent. You may use any number that you choose to replace the coefficients. Be sure to leave the variables the same. For example, 8(3j + 7 + 3j) looks like Sarah’s expression but is not equivalent.
Translate the algebraic expression you created in Question 1 to a verbal expression.
Part 2: Writing Equivalent Expressions
You will now use mathematical properties to create two expressions that are equivalent to the expression you created in Question 1. Make sure you show all steps in your work.
Use either the commutative property or combine like terms to create an equivalent expression.
Use the distributive property to create an equivalent expression.
Pick a number from 1 to 10. Use that number to verify your three expressions (the original, the one from 3a, and the one from 3b) are equivalent by substituting it into each expression. Show all your work for complete credit.
Part 3: Finish the Story
Write a few sentences to end Sarah’s story. How many shark teeth did she find? How many shark teeth did John find? How much money did Sarah earn?

The histogram shows the number of points scored by a basketball team for one season.
Histogram named as ALTDCPoints Scored in One SeasonALTDC. 3 games scored between 69 to 76, 6 games scored between 77 to 84, games scored between 85 to 92 and 1 game scored between 93 to 100.
According to the histogram, in what percentage of games did the team score between 77 and 92 points?
Round your answer to the nearest percent.
The percentage of games did the team score between 77 and 92 points is 78%.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
We have,
Total games = 3 + 6 + 8 + 1 =18
and, number of games in which points between 77 and 92.
= 6 + 8
= 14
Now, the percentage of games did the team score between 77 and 92 points
= 14/18 x 100
= 77.777%
= 78%

What is the Volume of the box 385 cubes?
Answer:You can calculate the volume of a box by multiplying length x width x height. Using the example of the single wall box this will be 102 x 102 x 102 which equals 1,061,208 cubic millimeters (㎣).
Step-by-step explanation:
The Volume of the box is 385/27 inch³.
What is Volume?The area that any three-dimensional solid occupies is known as its volume. These solids can take the form of a cube, cuboid, cone, cylinder, or sphere.
Many forms have various volumes. We have studied the several solids and forms that are specified in three dimensions, such as cubes, cuboids, cylinders, cones, etc., in 3D geometry. We will discover how to find the volume for each of these shapes.
Length = 11/3 inch
width - 5/3 inch
Height = 7/3 inch
So, the Volume of cuboidal box
= l w h
= 11/3 x 5/3 x 7/3
= 385/ 27 inch³
Also, Number of small cube = Volume of box/ Volume of small cube
385 = Volume of box / (1/27)
Volume of box = 385/ 27 inch³
