dieon has 3/4 pound of dog treats he will give his dog 1/8 of treats everyday how long will the bag last
Alexeev081 [22]
Amount of dog treat that Dieon has = 3/4 pound
Amount of dog treat that Dieon gives his dog each day = 1/8
Let us assume the number of days the dog treat will last = x
Then
(1/8) * x = (3/4)
x/8 = 3/4
x = (3 * 8)/4
   = 3 * 2
   = 6
So we can see from the above deduction that the dog treat will last for 6 days. I hope the procedure is clear enough for you to understand.

Circle O has a radius of 5 centimeters and central angle AOB with a measure of 60°. Describe in complete sentences how to find t
jeyben [28]

Answer:

We can use the formula for finding arc length given ccx central angle and radius.(insert formula below) We then substitute 5 in for r and and 60 for x. We multiply 2 pi times 5 which gives us 10. We then reduce the fraction of 60/360 to 1/6. We multiply 10 pi by 1/6 and that gives us

10 pi/6 or 5 pi/3

Step-by-step explanation:

We can use the formula

2\pi  \times r( \frac{x}{360} )

to find the arc length where r is the radius.

and x is the arc measure.

Plug it in for the numbers

2\pi \times 5( \frac{60}{360} )

Multiply 2 pi times 5=10 pi

10\pi( \frac{60}{360} )

Simplify 60/360 to 1/6

10\pi \times  \frac{1}{6}  =  \frac{10\pi}{6}

Reduce it to

\frac{5\pi}{3}

In a school egg drop challenge 136 of the eggs broke out of 200 total what percent of eggs survived the drop ?
dusya [7]

To make this equation easier, we can just divide the data by 2, so that the exact number of eggs that survived, is the percentage that survived.

Explanation:

200 = 200    Total Eggs

136  = 136   Eggs That Broke

So, the ratio of eggs that broke to total eggs is:

136 / 200

So, subtract the number of eggs that broke to the total eggs, to find the amount that survived.

200 - 136 = 64

So now we know that, 64 eggs of 200 survived.

Which means, that 32% off the eggs had survived.

Nataly [62]
The person above me is right!! I kinda got confused because i thought it was asking what sea level is the diver now BUT its asking for the elevation, so you need to subtract.
