If the volume of a sphere is 38808 cubes then find its surface area

find the length of DE if D is between points C and E, CD = 6.5 centimeters, and CE = 13.8 centimeters.

grin007 [14]

Answer:

DE = 7.3 cm

Step-by-step explanation:

All you have to do is take the length of the full line (13.8 cm) and subtract it by the first part (6.5 cm). Doing this gets you the final length of DE with is 7.3 cm.

Suki buys dog food in large 13.4-pound bags. She feeds her dog 0.3 pound of food twice a day. How many full days will the bag of

kozerog [31]

Hi!

Suki feeds her dog 0,3 pound of food twice a day, which means that in one day, Suki gives her dog 2 * 0,3 = 0,6 pound of food.

The total amount of dog food Suki bought for her dog is 13,4 pound-bag. To find the number of days the bag of dog food will last, we have to divide the total amount of the bag of dog food, which is 13,4 pounds, by the amount of what Suki gives her dog every day, which is 0,6 pound of food, like this:

13,4/0,6 = (multiply both values with 10) = 134/6 = 22,33

Because it is asked for the number of full days, in this case that's the lower whole number, 22 is the answer.

The bag of dog food will last full 22 days.

Hope this helps!

Determine if the side lengths could form a triangle. Use an inequality to prove your answer.

podryga [215]

9514 1404 393

Answer:

a) no

b) yes

c) maybe (no)

Step-by-step explanation:

There are two versions of the triangle inequality. One requires ...

a + b > c

for any triple of side measures a, b, c.

The other allows ...

a + b ≥ c

which admits "triangles" that have zero height and look like line segments.

Most questions asking "do these lengths form a triangle" are concerned with the "greater than" case, and disallow the "or equal to" case.

__

a)

$16+21=37\ngtr39\qquad\text{not a triangle}$

b)

$27+34=61>58\qquad\text{could be a triangle}$

c)

$9+29=38\ge38\qquad\text{could be a triangle if "equal to" is allowed}$
