4 0

Answer:

  • Jenny 1.75 miles, Keith 4.75 miles, Jonna 9.5 miles

Step-by-step explanation:

<u>Distance per person:</u>

  • Jenny - x, Keith - y, Joanna - z

<u>Equation as per given:</u>

  • y = x + 3
  • z = 2y = 2(x + 3)
  • x + y + z = 16

<u>Substitute and solve for x:</u>

  • x + (x + 3) + 2(x + 3) = 16
  • 2x + 3 + 2x + 6 = 16
  • 4x = 7
  • x = 7/4 = 1.75

Then

  • y = 1.75 + 3 = 4.75
  • z = 4.75*2 = 9.5

The Type B trees produces 120 pears.

<h3>What is meant by percentage?</h3>

A percentage is a number or ratio expressed as a fraction of 100 in mathematics. The percent sign, "%," is commonly used, but the abbreviations "pct.", "pct," and sometimes "pc" are also used. A percentage is a number with no dimensions; it has no unit of measurement.

<h3>How many pears did the Type B trees produce?</h3>
  1. Type A trees produced 20 percent more pears than Type B trees did
  2. Type A trees produced 144 pears.

Let us consider, Type B produced 100% pears.

So, Type A will produce 120%of B, that is 144

144 = 120/100 * B

simplifying the above equation, we get

144 * 100 = 120B

B = 14400/120

B = 120

The value of B = 120.

Hence, the Type B trees produces 120 pears

Therefore, the correct answer is option B) 120.

Volgvan

Answer:

Step-by-step explanation:

The answer is $11.55 for the week.

1) Since 1 watt is 0.001 kilowatts, 1500 watts is 1.5 kilowatts.

2) Multiply that by 7 for the week and that equals 10.5.

3) It takes her 10 minutes each day, so it takes 70 minutes per week, that is also 1.1 hours.

4) Multiply 10.5 kilowatts by 1.1 hours and you get 11.55.

5) The answer is $11.55 per week to dry Lisa's hair.
