Three containers have capacities if 3,5,and 9. How can you use these containers to measure exactly 9 liters of water

1 answer:

4 0

I'll have to know what the measurements of the containers. If it is in liters, then you would just use the container with the capacity of 9 liters.

Hope this helped :)

Kevin says that lines p and m will eventually intersect. Lines A and B intersect. Plane A contains lines p, m, and n. Line n is

ANTONII [103]

Answer:

No, because they are parallel.

Step-by-step explanation:

The lines $p$ and $m$ will not intersect, so Kevin is not correct.

It is given that planes A and B intersects. The plane A contains the line p, m and n on its plane. The lines p and m are parallel to each other. They are identical and move in the same direction.

Since the line p and m are parallel, they will not meet each other at any point because parallel lines does not intersect or meet at a point, they run parallelly along each other.

So, line p and m will not intersect.

Thus the answer is " No, because they are parallel."

It takes Evan 6 3/4 hours to mow 3 lawns. it takes him 2 1/3 hours to mow Mr. Smiths yard and 1 3/4 hours to mow Ms. Lee's yard.

Ratling [72]

Answer: $2\frac{2}{3}\ hours$

Step-by-step explanation:

Given: The total time taken by Evan to mow the 3 lawns = $6\frac{3}{4}=\frac{27}{4}\ \text{hours}$

Time taken by Evan to mow the first lawn = $2\frac{1}{3}=\frac{7}{3}\ \text{hours}$

Time taken by Evan to mow the second lawn = $1\frac{3}{4}=\frac{7}{4}\ \text{hours}$

Now,Time taken by Evan to mow the third lawn = $\frac{27}{4}-\frac{7}{3}-\frac{7}{4}$

⇒Time taken by Evan to mow the third lawn = $\frac{81-28-21}{12}$

⇒Time taken by Evan to mow the third lawn = $\frac{32}{12}=\frac{8}{3}=2\frac{2}{3}\ hours$

Hence, the time taken by Evan to mow the third lawn = $2\frac{2}{3}\ hours$

To help restore a beach sand is being added to the beach at a rate of s(t) = 65+24sin(.3t) tons per hour, where t is measured in

Svetach [21]

s(t) = 65+24sin(0.3t)

where t is measured in hours since 5:00 a.m

3-hour period from 7:00 a.m. to 10:00 am

5 am to 7 am = 2 hours

5 am to 10 am = 5 hours

To find the number of tons we take integral of 2 to 5 of s(t)

∫ 2 to 5 s(t) = ∫ 2 to 5 (65+24sin(0.3t))

∫65+24sin(0.3t) dt = 65t - 80 cos(0.3t) + c

Now we plug in the bounds 2 and 5

∫ 2 to 5 (65+24sin(0.3t)) = 255.36787 = 255.268

255.268 tons of sand are added to the beach over the 3-hour period
