A) 6a=5b so a=5/6*b a/b=5/6
b) 6a=5b so 6/5*a=b b/a=6/5
c) a/b=5/6 so (a/b)*(2/7)=2a/7b=(2/7)(5/6)=(5/21)
d) 6a=5b so b=6a/5 Thus (a+b)/b=(a+6a/5)/(6a/5)=(11a/5)/(6a/5)=11/6
e) 6a=5b so a=5b/6 Thus (a+b)/(5a)=(5b/6+b)/(5*5b/6)=(11b/6)/(25b/6)=11/25
f) (3a+3b)/(a+b)=3=3/1

Note, I wasn't quite sure what you meant by \frac

I know E and F

e) 6a=5b so a=5b/6 Thus (a+b)/(5a)=(5b/6+b)/(5*5b/6)=(11b/6)/(25/6)=11/25
f) (3a+3b)/(a+b)=3=3/1

You believe that eating an apple a day is healthy and want to design an experiment to find out. You have available 40 volunteers
Gwar [14]

The best design for this experiment would be a repeated measures design. This is ideal to determine if eating an apple makes you healthy.

<h3>What is an experimental design?</h3>

An experimental design refers to the general structure of an experiment including how people are distributed into the control and experimental group to test a specific phenomenon.

<h3>What is a repeated measures design?</h3>

In a repeated measures design all participants are both parts of the control group, in this case, people who do not eat apples, and the experimental group, or people who eat apples.

<h3>What does this design imply?</h3>

In the case of determining if eating an apple every day, this design implies:

  • All participants will be asked to not eat apples every day for a specific period such as one or two months, and health levels will be measured during this time.
  • After the first step, all participants will be asked to eat an apple every day during the period, and their health will be measured.
  • The researcher can compare the results of each participant, which is more accurate than comparing one participant to another.

I need help please. I need the the discount and selling price. Thank you
salantis [7]

Answer:

<h2><u>15.12 is the discount</u></h2><h2><u>68.88 is the sell price</u></h2>

Step-by-step explanation:

When you are taking off percentages from numbers, you first want to make the percent a number. This step is super simple. Just divide the 18 by 100

This gets you 0.18

Now multiply

84 * 0.18 = 15.12

So 15.12 is the discount

Then take 84 and subtract 15.12

84 - 15.12 = 68.88

So 68.88 is the sell price

Peter is trying to buy fencing for the perimeter of his garden. His garden is in the shape of a rectangle with a length of 2(x+6
MAVERICK [17]

Given that, the length of the garden is 2(x+6)feet and width is 3.5x feet.

So, length : l = 2(x+6) and width = 3.5x.

To find the fence of the garden we need to find the perimeter of the rectangle.

Formula to find the perimeter is:

p = 2l + 2b

= 2*2(x+6) + 2*3.5x

= 4(x+6) + 7x By multiplication.

= 4x + 24 + 7x By distribution property.

= 11x + 24 Combining the like terms.

So, he need to buy 11x + 24 feet fencing.

Hope this helps you!
