It took Kim 2 hours 34 minutes to type an
11 page research paper for Biology. What was
Kim's average typing speed?
How
Answer:
4.7 seconds per word
Step-by-step explanation:
11/2.34=4.7
(Im only guessing)
The average speed of Kim is 4.2857 pages per hour.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
Given that,
It took Kim 2 hours 34 minutes to type an 11 page
1 hour = 60 minutes
1 minute = 1/60 hour
34 minutes = 34/60 hour = 0.567 hour
Total hour = 2.567
Now,
Average speed = Number of pages / Number of hour
Average speed = 11/2.567
Average speed = 4.2857 pages per hour.
Hence "The average speed of Kim is 4.2857 pages per hour".

. Find the quotients.
a) (x2 - 4) =/(x + 2)
c) (4x2 - 1) / (2x + 1)
Answer:
[tex]\frac{x^2-4}{x+2} = x-2\\\frac{4x^2-1}{2x+1} = 2x-1[/tex]
Step-by-step explanation:
a) (x2 - 4)/(x + 2)
We can simply use factorization to solve the given question.
Here the first term will be numerator and second term will be denominator.
We will factorize the numerator.
So,
[tex]\frac{x^2-4}{x+2}[/tex]
Using formula, [tex]a^2+b^2 = (a+b)(a-b)[/tex]
[tex]\frac{x^2-4}{x+2}\\= \frac{(x^2)-(2)^2}{x+2}\\=\frac{(x+2)(x-2)}{x+2}\\= x-2[/tex]
b) (4x2 - 1) / (2x + 1)
We can simply use factorization to solve the given question.
Here the first term will be numerator and second term will be denominator.
We will factorize the numerator.
[tex]\frac{4x^2-1}{2x+1}[/tex]
Using formula, [tex]a^2+b^2 = (a+b)(a-b)[/tex]
[tex]= \frac{(2x)^2-(1)^2}{2x+1}\\=\frac{(2x+1)(2x-1)}{2x+1}\\= 2x-1[/tex]
Hence,
[tex]\frac{x^2-4}{x+2} = x-2\\\frac{4x^2-1}{2x+1} = 2x-1[/tex]
The Temperature is 50F. The temperature will decrease by 4F each hour. Let h be the numbers of hours.
When will the temperature below 32F
Write inequality for this equation.
C. and D. arrows are suppose to have lines under them.
A. 50 - 4h< 32
B. 50 + 4h < 32
C. 50 + 4h <_32
D. 50 - 4h <_ 32
Answer:
a. 50 - 4h < 32
Step-by-step explanation:
The question is "When will the temperature be below 32F?" so it can't be less than or equal to (≤), it has to be less than (<).
If the temperature is decreasing every hour you have to decrease 4 for each hour.

What is proportion?In general, the term "proportion" refers to a part, share, or amount that is compared to a total. According to the concept of proportion, two ratios are in proportion when they are equal.
A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.
Given:
Number of Tickets Cost
2 $17.00
3 $25.50
4 $34.00
5 $42.50
As, y=rx
r= y/x
r= 17/2
r= 8.5
again, r= 34/4
r= 8.5
Hence, the relation is y= 8.5 x.

Madison has set up a lemonade stand outside her house and sells small cups and large cups of lemonade. Each small cup holds 12 ounces of lemonade and each large cup hold 22 ounces of lemonade. Madison used 1240 ounces of lemonade and sold 10 more large cups than small cups. Write a system of equations that could be used to determine the number of small cups sold and the number of large cups sold. Define the variables that you use to write the system. And add the system of equations to your answer.
Answer:
small cups=30
large cups=40
Step-by-step explanation:
let x be the number of small cups and y the number of large cups.
-Given that 10 more cups than small cups of lemonade were sold:
#Before the 10 more were sold, the number of x and y sold were equal>
The number of small cups sold was 30
(02.03 MC) Triangle DOG was rotated to create triangle D'O'G''. Describe the transformation using details and degrees. (10 points) Triangles DOG and D prime, O prime, and G prime are shown. D is at negative 2, 1. O is at negative 3, 3. G is at 1, 1. D prime
Answer and Step-by-step explanation: Rotation is a "movement" of a geometric figure in order to transform one in another. In rotation, the shape and size of the figure is the same, so they are congruent.
A geometric figure can be rotated clockwise or counterclockwise and by different angles.
One way to recognized the angle of rotation is comparing the points of the figure and its rotated image.
On the figure below, triangle DOG has coordinates:
D (-2,1)
O (-3,3)
G (1,1)
And its image:
D' (2,-1)
O' (3,-3)
G' (-1,-1)
Comparing both set of coordinates, we observe:
D (-2,1) → D' (2,-1)
O (-3,3) → O' (3,-3)
G (1,1) → G' (-1,-1)
that the coordinates for ΔDOG and ΔD'O'G' are opposite to each other, i.e.:
(x, y) → (-x,-y)
rotating counterclockwise.
Since coordinates are opposite and rotation is counterclockwise, ΔD'O'G' is rotated by 180° related to ΔDOG.

Tyson and Ariana each invested $2,500 in separate accounts. Tyson’s interest rate is 5.75% and is compounded annually. Ariana’s simple interest rate is 5.75%. Neither will make any additional deposits or withdrawals. At the end of 6 years, how much more has Tyson earned? Round your answer to the nearest cent.
Answer:
Tyson's account will have $ 133.90 more than Ariana's account.
Step-by-step explanation:
In Tyson's case, he invests $ 2,500 in an account whose interest rate is 5.75% and is compounded annually. In turn, Ariana invests the same amount and for the same interest, but this is not compounded.
Thus, Ariana, at the end of her 6 years, will have a total amount in her account of $ 3,362.5 (((2,500 x 5.75 / 100) x 6) + 2,500), of which $ 862.5 will correspond to the interest generated.
Instead, Tyson's investment interests will be consolidated annually. Thus, in 6 years, this investment will evolve as follows:
-Year 1 --- 2,500 x 1.0575 = 2,643.75
-Year 2 --- 2,643.75 x 1.0575 = 2,795.76
-Year 3 --- 2,795.76 x 1.0575 = 2,956.52
-Year 4 --- 2,956.52 x 1.0575 = 3,126.52
-Year 5 --- 3,126.52 x 1.0575 = 3,306.29
-Year 6 --- 3,306.29 x 1.0575 = 3,496.40
Thus, at the end of the 6 years, Tyson will have $ 3,496.40 in his account. Thus, Tyson's account will have $ 133.90 more than Ariana's account.
