Michael has a sink that is shaped like a half-sphere. The sink has a volume of 3000 3 in3. One day, his sink is clogged. He has

jarptica [38.1K]

Answer:

Part a) $42\ cups$

Part b) $15\ cups$

Step-by-step explanation:we know that

The volume of the sink (half sphere) is equal to

$V=3,000\pi \ in^{3}$

Part a) One cup has a diameter of 6 in. and a height of 8 in. How many cups of water must Michael scoop out of the sink with this cup to empty it?

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=6/2=3\ in$ ----> the radius is half the diameter

$h=8\ in$

substitute the values

$V=\pi (3)^{2}(8)=72\pi\ in^{3}$

To find the number of cups divide the total volume of the sink by the volume of the cylinder

$\frac{3,000\pi}{72\pi} =41.67\ cups$

Round to the nearest whole number

$41.67=42\ cups$

Part b) One cup has a diameter of 10 in. and a height of 8 in. How many cups of water must Michael scoop out of the sink with this cup to empty it?

The volume of the cylinder is equal to

$V=\pi r^{2}h$

we have

$r=10/2=5\ in$ ----> the radius is half the diameter

$h=8\ in$

substitute the values

$V=\pi (5)^{2}(8)=200\pi\ in^{3}$

To find the number of cups divide the total volume of the sink by the volume of the cylinder

$\frac{3,000\pi}{200\pi} =15\ cups$

John is creating a Thanksgiving display at the store where he works, using only canned pumpkin and canned green beans. He needs

alukav5142 [94]

This is a part:part ratio. to solve it we need to convert it into a part:whole ratio. we do this by adding the parts. the ratio of pumpkin cans to total cans is 5:7. 140/7=20. 20x5=100. 20x2=40. The answer is B. 40 cans.

Given the Standard Form equation y - 6x = 4

malfutka [58]

Answer: <u>6 is the slope and 4 is the y-intercept.</u>

Step-by-step explanation:

Based on the question, I feel this is the best way to answer your question. I'm assuming you are in a basic graphing class.

The best, most useful thing for you right now would be to learn slope-intercept form, y = mx + b, where m and b are constants.

Simply add 6x to both sides to get into this form

y = 6x + 4.

In slope-intercept form, m is the slope, and b is the y-intercept. Thus, 6 is the slope and 4 is the y-intercept.

Hope it helps and lmk if you need more <3 :)

Karen spent 7/10 hour reading and 3/5 hours writing in her journal how much longer did karen spend reading than writing in her j

STatiana [176]

Answer: 1/10

Step-by-step explanation:

From the question, we are informed that Karen spent 7/10 hour reading and 3/5 hours writing in her journal.

To calculate how much longer karen spent reading than writing in her journal, we have to subtract 3/5 from 7/10. This will be:

= 7/10 - 3/5

Note that the lowest common multiple of 5 and 10 is 10.

= 7/10 - 6/10

= 1/10

Therefore, the answer is 1/10
