Hiroki's goal is to collect $40 for a school fundraiser. He already collected $26.50. Hiroki wants to know how much more money he needs to collect.
Let m be the amount of money Hiroki still needs to collect. Describe the situation with an equation.

Answers

40-26.50= 13.50
You subtract 26.50 from 40 which will give 13.50

Hiroki needs to collect $13.50 more.

What is Algebra?

Algebra, a discipline of mathematics where abstract symbols rather than concrete numbers are subjected to arithmetic operations and formal transformations. The idea that there is such a separate branch of mathematics, as well as the term algebra to identify it, came about gradually through time. It tries to find solutions to equations that contain one or more unknown quantities. Although early mathematicians would not have been familiar with such a concept, the word "equation" is frequently employed to conveniently represent these operations when discussing the early history of algebra.

As per the given data:

Total amount to be collected = $40

Amount already collected = $26.50

To find the amount of money still to be collected (m):

Total amount to be collected - Amount already collected

= $40 - $26.50

= $13.50

Hence, Hiroki needs to collect $13.50 more.

Part A: The medium container

Part B: The medium container is the best but because it has the lowest price in relation to the amount you are receiving. The big container is 30 ounces and $9. if you divide 30 by 9 you get $3.3333. The small container is 8 ounces and $2. if you divide 8 by 2, you get $4. The medium container is 15 ounces and 4.95 dollars. If you divide 15 by $4.95, you get 3.03030303 which is less money than the other containers. :))

What is the difference between a third-person limited narrator and a third-person omniscient narrator? Now, imagine that you are helping a library move. You are lifting boxes of books onto a cart. Most of the boxes are full of many books, but one of the boxes was closed, only having a few books in it. You go to lift this box, not knowing it has less mass, with the same amount of force as you used to lift the full boxes. How will the acceleration of this box compare to the acceleration of a full box? Newtons second law of motion tells us that if the force remains constant and the mass is decreased, the object will accelerate at a faster rate. Because the acceleration increases when the mass decreases, we say that acceleration is inversely proportional to mass.Give an example of a situation where you might use the mathematical formula for Newton's second law to solve a problem. Explain how the formula would be useful in this situation. from Where I Lived, and What I Lived For in Waldenby Henry David ThoreauLook at a meeting-house, or a court-house, or a jail, or a shop, or a dwelling-house, and say what that thing really is before a true gaze, and they would all go to pieces in your account of them. Men esteem truth remote, in the outskirts of the system, behind the farthest star, before Adam and after the last man. In eternity there is indeed something true and sublime. But all these times and places and occasions are now and here. God himself culminates in the present moment, and will never be more divine in the lapse of all the ages. And we are enabled to apprehend at all what is sublime and noble only by the perpetual instilling and drenching of the reality that surrounds us. The universe constantly and obediently answers to our conceptions; whether we travel fast or slow, the track is laid for us. Let us spend our lives in conceiving then. The poet or the artist never yet had so fair and noble a design but some of his posterity at least could accomplish it.Let us spend one day as deliberately as Nature, and not be thrown off the track by every nutshell and mosquitos wing that falls on the rails. Let us rise early and fast, or break fast, gently and without perturbation; let company come and let company go, let the bells ring and the children crydetermined to make a day of it. Why should we knock under and go with the stream? Let us not be upset and overwhelmed in that terrible rapid and whirlpool called a dinner, situated in the meridian shallows. Weather this danger and you are safe, for the rest of the way is down hill. With unrelaxed nerves, with morning vigor, sail by it, looking another way, tied to the mast like Ulysses. If the engine whistles, let it whistle till it is hoarse for its pains. If the bell rings, why should we run? We will consider what kind of music they are like. Let us settle ourselves, and work and wedge our feet downward through the mud and slush of opinion, and prejudice, and tradition, and delusion, and appearance, that alluvion which covers the globe, through Paris and London, through New York and Boston and Concord, through Church and State, through poetry and philosophy and religion, till we come to a hard bottom and rocks in place, which we can call reality, and say, This is, and no mistake; and then begin, having a point d'appui, below freshet and frost and fire, a place where you might found a wall or a state, or set a lamp-post safely, or perhaps a gauge, not a Nilometer, but a Realometer, that future ages might know how deep a freshet of shams and appearances had gathered from time to time. If you stand right fronting and face to face to a fact, you will see the sun glimmer on both its surfaces, as if it were a cimeter, and feel its sweet edge dividing you through the heart and marrow, and so you will happily conclude your mortal career. Be it life or death, we crave only reality. If we are really dying, let us hear the rattle in our throats and feel cold in the extremities; if we are alive, let us go about our business.Time is but the stream I go a-fishing in. I drink at it; but while I drink I see the sandy bottom and detect how shallow it is. Its thin current slides away, but eternity remains. I would drink deeper; fish in the sky, whose bottom is pebbly with stars. I cannot count one. I know not the first letter of the alphabet. I have always been regretting that I was not as wise as the day I was born. The intellect is a cleaver; it discerns and rifts its way into the secret of things. I do not wish to be any more busy with my hands than is necessary. My head is hands and feet. I feel all my best faculties concentrated in it. My instinct tells me that my head is an organ for burrowing, as some creatures use their snout and fore paws, and with it I would mine and burrow my way through these hills. I think that the richest vein is somewhere hereabouts; so by the divining-rod and thin rising vapors I judge; and here I will begin to mine.Which of the following best describes the intended audience for this passage?A.all Americans B.the speakers philosophical contemporariesC.city dwellersD.the speakers detractorsE.highly-educated and well-to-do individualsPlease select the best answer from the choices providedABCDE Can someone please check my answer??!
