Answer:
11. a)50 12. a)40
Step-by-step explanation:
sum of all three angles of trinagle=180
so
111.
80+50+x=180
130+x=180
x=180-130
x=50
12.
60+90+x=180
150+x=180
x=190-150
x=40
Answer:

Step-by-step explanation:
quotient = divide
it's ten less than what the quotient is.
She can ride a bike 7 miles per hour
19/15 OR 1 and 4/5
First find a common denominator, which in this case is 15. So put 15 as each of the fractions denominators. Then multiply the numerator by what you multiplied to the denominator.
EXAMPLE
3/5 x 3/3 = 9/15
2/3 x 3/3 = 10/15 Ten plus nine =s 19. Keep the denominator the same. Turn into a mixed number by figuring out how many times 15 goes into 19 (once) and addng what's left. (4/5) You should get 1 and 4/5
Answer:
Option A, Shannon paid $ 7 per hour to labor than Joni
Step-by-step explanation:
Total amount paid by Shannon = $339.50
Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)
Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5
Total cost of 1 hours of labor paid by Shannon $65 per hour
Total amount paid by Joni = $455
Total cost of 2.5 hours of labor paid by Joni = $455- $$310
Total cost of 1 hours of labor paid by Joni = $145/2.5
Total cost of 1 hours of labor paid by Joni = $ 58
Hence, Shannon paid $ 7 per hour to labor than Joni
Option A is correct
