Sand for use on icy roads is stored in a conical pile 14.2 m high and with a base diameter of 34.4 m calculate the volume of the pile if one sander can take 6.9 m of sand, how many sanders can be filled from the pile

Answers

Answer 1

Answer:

1. The volume of the pile is 4,399.7719 m^3

2. The number of sanders to be filled from a pile is 638

Step-by-step explanation:

Here, we firstly would calculate the volume of the pile

Mathematically, that will be;

V = 1/3 * pi * r^2 * h

from the question, h = 14.2

Mathematically, r = d/2

r = 34.4/2 = 17.2 m

So the volume will be:

V = 1/3 * 3.142 * 17.2^2 * 14.2

V = 4,399.7719 m^3

To find the number of sanders to be filled,

we simply divide the volume obtained by the volume a sander can take

That will be;

4,399.7719/6.9

= 637.6 which is 638

Convert 3 weeks to hours. Use a lable.

Answers

Answer: 504 hours.

Step-by-step explanation: I am assuming it says, use a table not a lable.

Well, I can't make a table, so I will tell you where to put everything in a table.

We start with placing one day, one day is 24 hours. One day goes on the top, 24 hours goes on the bottom. Then, we know there are 7 days in a week, so we jump ahead, we multiply 24 by 7 and 1 by 7.

24 x 7 = 168 and 1 x 7 = 7

So for every week, it is 168 hours. Now we need to find three weeks. So we multiply 7 x 3 to get the days. which is 21. Now we need to multiply the hours by the 3 weeks. So we multiply 168 by 3 which is 504.

So 504 hours are in 3 weeks.

The response to a question has three alternatives: A, B, and C. A sample of 120 responses provides 60 A, 12 B, and 48 C. Show the frequency and relative frequency distributions.

Answers

Answer:

CLASS FREQUENCIES RELATIVE FREQUENCIES

A 60 0.5

B 12 0.1

C 48 0.4

TOTAL 120 1

Step-by-step explanation:

Given that;

the frequencies of there alternatives are;

Frequency A = 60

Frequency B = 12

Frequency C = 48

Total = 60 + 12 + 48 = 120

Now to determine our relative frequency, we divide each frequency by the total sum of the given frequencies;

Relative Frequency A = Frequency A / total = 60 / 120 = 0.5

Relative Frequency B = Frequency B / total = 12 / 120 = 0.1

Relative Frequency C = Frequency C / total = 48 / 120 = 0.4

therefore;

CLASS FREQUENCIES RELATIVE FREQUENCIES

A 60 0.5

B 12 0.1

C 48 0.4

TOTAL 120 1

Find the slope intercept equation of the line

PLEASE SOMEONE HELP WHO UNDERSTANDS HOW TO DO THESE BECAUSE I KEEP GETTING THE WRONG ANSWER!!!

Answers

Step-by-step explanation:

For every 3 blocks across, the line graph goes up by 2 blocks. Therefore the slope of the line is 2/3.

The line also intercepts the y-axis at -3.

Hence the slope-intercept form is y = 2/3 x - 3.

When doing slope I suggest using slope triangles:) make a dot at -3, then go to the right 3 spaces, from this point go up 2 spaces and make another dot. Do that for as long as you need your line to be:) When you go up 2 spaces use that last dot and go over 3 spaces and up 2. Keep repeating

A doghouse is to be built in the shape of a right trapezoid, as shown below. What is the area of the

Answers

A: 59.5ft^2

You need to add the top length and the bottom length, and then multiply that answer by the vertical height of the shape.

7 + 10 = 17
17/2 = 8.5
8.5 x 7 = 59.5

You can also double check this by working out the area of the square and then the area of the triangle, and adding them together.

7 x 7 = 49
7 x 3 = 21
21/2 = 10.5
49 + 10.5 = 59.5

Jacob decided to start saving for college. After 3 months, he had saved $174. His friend Victoria was inspired to do the same. After 6 months, she had saved $360. If they are both saving money at a constant rate, how many more dollars per month does Victoria save than Jacob?

Answers

Answer:

$2 more.

Step-by-step explanation:

In this question, we have to find how much more money Victoria is saving.

We know that Jacob saved $174 in 3 months.

We also know that Victoria saved $360 in 6 months.

Lets find how much money they save per month:

Jacob:

174 ÷ 3 = 58

Victoria:

360 ÷ 6 = 60

Jacob is saving $58 per month and Victoria is saving $60 per month.

This means that Victoria is saving $2 more than Jacob per month.

Nancy is wrong because 78 is close to the benchmark 12 and 58 is close to the benchmark 12 and 12 + 12 = 1.

Nancy is wrong because 78 is close to the benchmark 1 and 58 is close to the benchmark 0 and 1 + 0 = 1.

Nancy is correct because 78 is close to benchmark 1 and 58 is close to benchmark 12 and 1 + 12= 112. .

Poems and Quos for People out there who are like me....Poem of Life:You can leave, but don't leave the world behind.Make your choices, choose smart and wise.Take time to live life to the fullest and the best, and breathe the sweet smell of life.You have your choices, you choose between, make the right one and you shall see.Life has surprises, life has its turns, but you must get through for you to live and experience.Read it when you need to, When times are hard and sad. With anger and pain, but always see yourself as number one, Do what you think is right for yourself and other, Even though some decisions you make will be for yourself.Strong:We are strong, we all carry great feelings for the ones we love, if they are not strong, help and carry them to the end. People need to be strong in times of need, or maybe just in general, people who are not strong need people who are, to help them lead the way, till both are equally strong, and together people and people, strong or weak either way can make great deeds in life, and immortal marks in the world. Trees:Leaves fall to the ground, like a old tree losing its memories,Sap drips on cars, and onto the ground, from the face of the tree, like its crying.It sways in the wind, trying to keep its balance, and to stay strong,The wind rustles through the branches and leaves, giving advice and messages,Carved scars, in the hard, tough bark of a tree.We, us people are trees of our own, as we grow old, we forget our memories, but we always make more, in time.We cry, and produce our feelings, and they drip, into or onto others.We sway, as we try to stay strong, and to keep our balance.And we produce advice and messages, from our minds, as we think, in deep thought.We are trees, strong, tall, structures, that live life, produce, and die off. Friends:There's this little thing called friendship.I experience it every day,And will always be thankful that I have friends,Because they have helped me along the way.A friend is a flashlight in the dark, or a somebody who will hold your hand in the dark,A rainbow after the storm,The sunshine after a cold, damp day,The glue when you are torn.I have friends I love like sisters and brothers.(I know they love me too.)They'll be there through thick and thin,For you must know that friendship can be true.Beauty:We don't understand the beauty inside so we criesAll the tears that fall from our eyesAnd the pain we try to hideA few know about our thoughtsAnd the scars on our body from the people who tauntWe want to stop 'this' only for some reliefBut with all the grief we feel within it's harder to stopThen it is to beginParents don't understand, And so they just shoutAnd make them feel even more worthless, And full of doubtThey tried to explain a thousand timesBut is never able to seem to findWhat will make them listen Instead of fight, So this poem is endingLet's all find an alternative from the sharp tools across our skinAnd hopefully you will noticeAll the beauty within. Memories within the Scars:We make permanent marks along our bodies with every bad memory hidden withinWe know that others do this as well, as they have sharp, and precise lines with memories within.We dont realize the beauty within us, nor do the others, they have problems much alike, and they dont know what to do.Except to drown in their sorrows, keeping the pain, anger, and sadness hidden underneath their thick hearts.We only sees ourselves as our own, we can trust nobody but ourselves.Life isnt easy, its a slide with many ups and downs, its a cakewalk full of challenges, and a cruel place where you need to work to survive, its a world of the fittest thrives.Even if it means to make permanent memories on their bodies, to remind them.But is it the best? Is it the best for them?Rivers and Roads:Life will have its current and life will have its road, let life take its course but know that you have to put effort into making you life, what you do is what makes you, but you can change anything within your life, you just need you put your mind to it, if you dont put effort you wont pass that steep hill, if you stay in that one spot of the slow current you wont go anywhere. So make your life, change it, shape it, dont let it control you.Pls don't feel bad about the people out there who are like this, life will go it's way and change for the matter. Maybe if you come across such a person like this, encourage them, you don't have to do this but don't always steer away.
