What is sum in mathematics?
A summation, also known as a sum, is the outcome of adding numbers or quantities arithmetically. A sum always has an even number of terms. There might be as few as two or as many as a hundred, thousand, or million phrases. Some sums have an unlimited number of terms.

The speed limit in Canada is 100km/hr. What is the value of this limit in mi/hr given 1mi = 1.609km?
Answer:
62.14 miles per hour
Answer: 100 km/h is equal to 62.14 mph
So, 100 km/h is equal to 62.14 miles per hour.
Answer:
62.15 mi/hr
Step-by-step explanation:
Given:
1 mile = 1.609 kmAs both speed limits are given "per hour", we only need to convert 100 km to miles. To do this, set up and solve a ratio for "miles to kilometers", where x is the number of miles to 100 km:
[tex]\implies \sf 1 : 1.609 = x : 100[/tex]
[tex]\implies \sf \dfrac{1}{1.609} = \dfrac{x}{100}[/tex]
[tex]\implies \sf \dfrac{1}{1.609} \cdot 100= x[/tex]
[tex]\implies \sf x= \dfrac{100}{1.609}[/tex]
[tex]\implies \sf x= 62.15040398...[/tex]
Therefore, 100 km/hr = 62.15 mi/hr (2 d.p.)

Frank camped and hiked for three days. He hiked around three of the lakes.
He estimated his hiking distance to be more than 35 miles but less than 40
miles. Which three lakes did Frank hike? explain your answer
a = 6.51
b = 8.74
c = 21.25
d = 18.68
e = 15.33
The three lakes that Frank walked were Lakes A, B, and C. This may be deduced from the distances between the lakes as well as the total distance that Frank traveled, which was more than 35 miles but less than 40 miles.
How do locate the lakes when hiking?You may determine which lakes Frank walked to by combining a total of three lakes from the set of lakes provided in the puzzle.
Assuming Frank hiked Lakes A, B, and C, the distance is;
= 6.51 + 8.74 + 21.25
= 36.5 miles
Lakes A, B, and D:
= 6.51 + 8.74 + 18.68
= 33.93 miles
Lakes A, B, and E:
= 6.51 + 8.74 + 15.33
= 30.58 miles
It can be observed that Lakes A, B, and C are the only ones that meet the requirement of having a distance of fewer than 40 miles but more than 35 miles.
The following questions should be asked next:
Lakes: a = 6.51
b = 8.74
c = 21.25
d = 18.68
e = 15.33

Pam takes her truck in for basic service. The service agent says a few extra repairs are also needed, so Pam adds the cost of those repairs in her head, rounding to the nearest $10. The costs are as follows: Wheel alignment: $110 Transmission fluid flush: $75 Cabin air filter: $23 What is her total estimate for the repairs?
The total estimate for the repairs when Pam takes her truck in for basic service is $200.
How to illustrate the information?Based on the information given, the costs are as follows:
Wheel alignment: $110 = $100
Transmission fluid flush: $75 = $80
Cabin air filter: $23 = $20
Therefore, the total estimate for the repairs will be:
= $100 + $80 + $20
= $200

2. Error Analysis For the figure below, Adam was asked to draw all lines of reflection. His work is shown. What error did Adam make?
The vertical line is correct, but the horizontal line is not.
This is because we can reflect the left half over the vertical line to have it produce the right half, and vice versa.
Unfortunately, the top half is not the same as the bottom half. For instance, the metal part at the bottom is not found at the top. Also the top and bottom shapes don't perfectly match.

Velma wants to buy a house that is listed for $195,000. Her bank offers a 30-year fixed-rate mortgage with an APR of 3.9%. What will her monthly house payment be?
Based on the amount that Velma wants to buy the house for and the fixed-rate mortgage offered by her bank, her monthly house payments will come to $919.75
What are the monthly house payments?The monthly house payments are constant so they are an annuity. The loan amount of $195,000 will be the present value of the annuity.
The monthly rate is:
= 3.9% / 12
= 3.9/12%
The number of periods is:
= 30 x 12
= 360 months
The monthly house payments is:
195,000 = Amount x (1 - (1 + 3.9/12%)³⁶⁰) / 3.9/12%
Amount = 195,000 / 212.01344311265715516703523151038

If I drove is 357.5 miles in 5 hours and 30 minutes how fast was I driving?
Answer:
65 Miles Per Hour
Step-by-step explanation:
357.5 divided by 5 1/2 equals 357 1/2 divided by 11/2, or 715/2 times 2/11 using reciprocals. Multiply and you get 1430/22 which simplifies down to 65. Therefore you were driving at 65 miles per hour
Janet just graduated from college, has a job she's scheduled to begin in 3 months and has decided to treat herself to 6 weeks of travel across South America before she buckles down and starts working full-time. To do the trip, she's thinking of applying for a personal loan of $3500, and the bank she uses for her checking and savings account has offered her an interest rate of 24%. She has a goal of paying off the trip within two years. PLEASE HELP ASAP!!
3) By the time Janet pays off the loan, the total interest she would have paid is D. $941.17.
4) By the time Jane pays off the loan, the total cost of her tip is B. $4,441.17.
5) The equation to find the new balance after each month's payment is D. New balance = Previous balance - Total monthly payment.
How is the monthly payment computed?The monthly payments can be computed by first computing the total payments (future value of the loan). Then, the above figure is divided by the number of periods.
For instance, the total cost of Janet's trip is $4,441.17. The payments are made for 24 months. Dividing $4,441.17 by 24 gives $941.17.
Data and Calculations:N (# of periods) = 24 months (2 x 12)
I/Y (Interest per year) = 24%
PV (Present Value) = $3,500
FV (Future Value) = $0
Results:
PMT = $185.05
Sum of all periodic payments = $4,441.17 ($3,500 + $941.17)
Total Interest = $941.17
Thus, Janet would have spent $4,441.17 to obtain a loan of $3,500 for her trip at 24% interest with 24 months for repayment.
