61.80 miles per hour is Jen's speed.

Given:
170 miles
2 hours and 45 minutes

2 hours and 45 minutes is 2 45/60 in fraction and can be simplified to 2 3/4 in fraction. 
2 hours and 45 minutes is 2.75 in decimal.  

Let us use the decimal form for our time:

Speed = distance / time
            = 170 miles / 2.75 hours
Speed = 61.818 miles per hour

61.818 miles per hour rounded to the nearest tenth is 61.80 miles per hour.

Speed= distance /time
distnace=170 miles
t=2 hours + 45 minutes *(1 hora / 60 minutes=2 hours + 0.75 hours=2.75 hours.

Speed=170 mile / 2.75 hours=61.818...miles/hour≈61.8 miles/hour.

Solution: 61.8 miles/hour.

13. Maria earns $8 per hour plus a 5% commission on the price
Pani-rosa [81]

Answer:

Inequality:

120 + 0.05x ≥ 200

Solution:

x ≥ $1,600

Her total weekly sales must be equal to or greater than $1,600

Step-by-step explanation:

Let x represent the weekly sales she must make to reach her goal.

Given;

Pay rate = $8

Weekly total work hours = 15 hours

Commission on sales = 5% = 0.05

Total weekly earnings is;

8×15 + 0.05×x

120 + 0.05x

Minimum Weekly target earnings = $200

So;

120 + 0.05x ≥ 200

Solving the inequality equation;

0.05x ≥ 200 - 120

0.05x ≥ 80

x ≥ 80/0.05

x ≥ 1600

x ≥ $1,600

Her total weekly sales must be equal to or greater than $1,600

Given that two digit numbers are used and one digit is drawn randomly.

Sample space = {10,11,...99}

n(S) = 90

32 is only one number favorable

Hence P(32) = 1/90

----------------------------

Odd numbers are exactly 45.

Hence prob (odd number) = 45/90 = 1/2

-------------------------------------

Multiples of 5 are 10,15,.....95

There are exactly 18 numbers.

Hence P(a multiple of 5) = 18/90 =1/5

Have an amazing day! <3
