Something is missing there is no given. But here are the given for this question:
Salary = $8.75 per hour
40 hour work week
52 work week per year
5 days of work per week
Gas mileage is 21 miles per gallon
Gas costs is 1.26 per gallon
Average speed is 45 miles per hour
Daily round trip to work and back home is 34 miles
a. Kevin’s annual salary is 8.75 per hour x 40 hour work week x 52 work week per year
= $18,200
b. Kevin will spend on fuel each week:
34 miles daily round trip x 5 day work week divided by 21 miles per gallon x 1.26 per gallon
= $10.20
c. Kevin will spend _ hours on commuting
= 34 miles is the daily round trip x 5 day work week divided by 45 miles average speed per hour
= 3.78 hours
Hope this helps!
Answer:
Step-by-step explanation:
<u>Given expression:</u>
<u>Find its value when x = 4 and y = 1, substitute:</u>
- 3(4 + 1) + 2*4² + (1 + 1)² =
- 3*5 + 2*16 + 2² =
- 15 + 32 + 4 =
- 51
Answer:
Step-by-step explanation:
Factorise the numerator and denominator
8a² - 2 ← factor out 2 from each term
= 2(4a² - 1) ← 4a² - 1 is a difference of squares
= 2(2a - 1)(2a + 1)
4a² + 4a + 1 ← is a perfect square
= (2a + 1)²
Thus
= 
← cancel (2a + 1) on numerator/ denominator
= 
=
It would be 20.4 km because if 1cm is 12km then you just have to multiply 1.7 x 12 = 20.4.
