Answer:

√113, or 11 if you want to round it.

Step-by-step explanation:

You can create a right triangle with the two points to get one side as 7 units and the other side as 8 units. You can then use the pythagorean theorem.

4. Suppose that you have an enormous grapefruit that is 92% water (by weight). The grapefruit weights 100 pounds. If the water c
Anton [14]

Answer:

80 pounds.

Step-by-step explanation:

Let W₁ be the initial weight of water in the grapefruit, W₂ be the weight of water in the grapefruit after evaporation, and M be the total weight of the grapefruit after evaporation. Assuming that, originally, the grapefruit weighed 100 pounds with a 92% water content and the weight of the "non-water" part of the fruit (100 - W₁) does not change. The final weight of the grapefruit (M) is given by:

W_1=0.92*100=92\\W_2=0.90*M\\W_2+(100-W_1) = M\\W_2=M-8\\(1-0.9)M=8\\M=80

The grapefruit now weighs 80 pounds.

If you are going somewhere that is 60 miles away and you're going 40 miles per hour the whole time how long will it take you to
Masja [62]
Velocity * time = distance

40 (miles / hour) * t (hours) = 60 (miles)

Take note how the units work. miles/hour * hours = miles. This is an indication that a formula we picked is correct.

Now, looking at our formula (and neglecting units at this point)

40t = 60
t = 60/40
<span>t = 1.5 hours</span>

Suppose P(C/D)=0.34, P(D)=0.11 , and P(D/C)=0.09. What is P(C) rounded to two decimal places?
Olegator [25]

So C/D=.34 And D=.11, now just plug D into the first equation.

C/.11=.34 Divide by .11

C=3.09090909

Now this rounded two decimal places is 3.09!

Hope this helps
