Answer:

Please see the answers below:

Step-by-step explanation:

The wrong answers are deleted only the correct answers are listed below:

  • Ryan earns $45 for 5 hours of work. The unit rate is $9 for 1 hour.
  • Jenna can drive her car 110 miles on 5 gallons of gasoline. The unit rate is 22 miles per gallon.
  • Claire saves $320 in 16 weeks. The unit rate is $20 per week.

  • % increase in price of gas = [(New Price - Original Price) / Original Price] x 100

% increase in price of gas = [($2.48 - $2.18) / $2.18] x 100

% increase in price of gas = [$0.3 / $2.18] x 100

% increase in price of gas = 13.76%

Melissa's employer matches retirement funds 1:2 up to 6% of salary. She makes $55,000 per year. How much should she contribute t
gtnhenbr [62]

Answer: $1100

Step-by-step explanation:

The employer contributes, along with Melissa, in the ratio of 1:2

Up to 6% of $55000, therefore 6/100 x 55000 = 3300

Split in the ratio of 1:2, she will contribute 1/3 of 3300 = 1100

and the employer will contribute 2/3 of 3300 = 2200

Geometry B: fill in the blank
olga_2 [115]

Answer:

The circumference of a circle is the distance around the entire circle, while arc length, s, is the distance <u>between</u> two points on the circle.

C = 2πr = 2π( <u>5</u><u> </u>) = 10π ≈ 31.4 units

3.14 is an approximation for π.

s = θ/360° (C)

mAB = 60°/360° ( 31.4)

= <u>1</u><u>/</u><u>6</u>(31.4) ≈5.2 units
