It took Kim 2 hours 34 minutes to type an
11 page research paper for Biology. What was
Kim's average typing speed?
How
Answers
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".

D. 50 - 4h <_ 32
Answers
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.

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.
Answers
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.

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.

Sam rented a truck for one day. There was a base fee of $16.95, and there was an additional charge of 73 cents for each mile driven. Sam
had to pay $172.44 when he returned the truck. For how many miles did he drive the truck?
Answers
Answer: 134 miles
Step-by-step explanation:
f(m) = 16.95 + 0.92m
140.23 = 16.95 + 0.92m
0.92m = 140.23 - 16.95
0.92m = 123.28
m = 123.28/0.92
m = 134 miles

(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
Answers
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.

The slop is rise over run
which means we need to find the rise over run of this equation:
So the question is how many times do you need to go up/down to get to the next plot on the graph? (Reminder up is positive while down is negative)
So, you go down 5 times which means the top of the slope is -5
Now, how many times do we need to run to get the next plot?
You need to run 4 times to the right to get the next point now we have all the things to solve the problem:
