Doira has a company that sells plants. She sells 34 for plants for $9,000 each her first day. The next couple days she sells 34 for $99,999 each. If she keeps selling them for $99,999 each for 100 weeks,how many plants will she have sold? How much money will she have made?

Answers

Answer:

1)23,800 plants.

2)$2,380,068,200

Step-by-step explanation:

1) if Doira sells 34 plants for $99,999 each for 100 weeks, she will have sold a total of 23,800 plants.

2.On the first day, Doira sold 34 plants for $9,000 each, so she made a total of 34 x $9,000 = $306,000.

In the following days, she sold 34 plants for $99,999 each, so her daily earnings were 34 x $99,999 = $3,399,966.

If she continues to sell 34 plants for $99,999 each for 100 weeks, she will sell a total of 34 x 100 x 7 = 23,800 plants.

Her total earnings from selling 34 plants for $99,999 each for 100 weeks will be 23,800 x $99,999 = $2,379,762,200.

Adding her earnings from the first day, her total earnings will be $2,379,762,200 + $306,000 = $2,380,068,200.

Answer: she would sell 340 plants and make $9,999,900

Step-by-step explanation:

34 x 100 =340

99, 999 x 100 = 9,999,900

Answer:

198

Step-by-step explanation:

length =11

width=18

Length times width = area

11 times 18 equals 198

i hope this helps! <3

Page 1, Answer:
168 cm

Explanation:

First we should find the area of the non-shaded parts

Length: 5cm
Width: 4cm
5x4=20
1st square= 20 cm

Length: 5cm
Width: 2cm
5x2= 10
2nd square= 10 cm

Now we add:
20+10=30

Shaded part:
11x18=198

We have to subtract the shaded part by the non shaded part:
198-30=168

Answer= 168cm


Page 2:

Answer 1:
Both are equal

Explanation:

Both are equal because:

A: 8+8+2+2

16+4=20
A=20cm

B: 5+5+5+5
5x4=20
B=20 cm

Answer 2:
16

Explanation:

Since we are already given the product we need to find the factors, square has 4 equal sides so we have to divide by 4:

64/4=16
Ans=16cm

Answer 3:
62cm

Explanation:
We need to divide the shape into 2.

Rectangle 1:
10+5+?+?

Since we already know what one side is it will be the same on the other side:

10+10+5+5
20+10=30

Rectangle 1=30cm

Rectangle 2:

Here we start to add and subtract:

Length: 10-5=5

Width: 6+5=11

5+5+11+11
10+22=32
32 cm

Total:
Now that we know both perimeters we add:

32+30=62

Total=62cm

From a log of wood of length (8x+12) m, a piece of length (4x+3) m was cut. Find the length of the remaining log of wood.


Grade#7

Answers

Answer: 4x+9

Step-by-step explanation: (8x+12)- (4x+3)

Answer: (4x+9)

Step-by-step explanation:

Log of wood = (8x+12)

piece length = (4x+3)

So, (8x+12) - (4x+3)

=> (8x+12) - 4x - 3

=> 8x-4x +12 -3

=> 4x + 9

So, the length of the remaining piece of wood = (4x+9)

Martin used a coordinate plane to design the garden shown. Each unit on the grid represents 10 yards.

How many square yards will the garden be after it is built? What is the total AREA of the garden?

Answers

The best way to solve this is to break the shape up into areas you know how to solve.

Lets divide this into the big rectangle being separated from the smaller rectangle at the bottom.

To find the height of the big rectangle, subtract one y-coord of 30 from the other y-coord 80.

80-30=50

To find the length of the big rectangle, subtract one x-coord of 10 from the other x-coord of 100.

100-10= 90

Multiply these to get the area of the big rectangle:

90 x 50 = 4500 units squared

Next, find the smaller recatngle’s area by repeating the previous steps:

Height: 30-10 = 20
Length: 70-40 = 30

Now find the area:

20 x 30 = 600 units squared

Finally, add both of these areas up to find the total area for the original shape:

4500 + 600 = 5100 units squared

Write and evaluate an expression that tells you to subtract 6 from 9 then subtract the difference from 12 and then multiply by 3 use at least two types of grouping symbols

Answers

Step-by-step explanation:

One possible expression using two types of grouping symbols is:

3 × [(12 - (9 - 6))]

This expression first subtracts 6 from 9 to get a difference of 3, then subtracts that difference from 12 to get a result of 9. Finally, it multiplies 9 by 3 to get a final answer of 27. The grouping symbols used are parentheses to group the subtraction of 6 from 9, and then another set of parentheses to group the subtraction of that difference from 12. The outermost grouping symbols are the multiplication symbol and the pair of brackets used for clarity.

Based on the information in the equation, which statements are true?





A. The cooler is meant to be used by only 24 players.

B. Before practice, there are 648 ounces of sports drink in the cooler.

C. If 24 players get drinks from the cooler, they will drink a total of 648 ounces of sports drink.

Answers

Answer:

Step-by-step explanation:

ounces of sports drink in the cooler.

C. Each player is expected to drink 24 ounces of sports drink during practice.

D. If no players take drinks from the cooler, there will be 648 ounces of sports drink in the cooler after practice.

Statement B is true: Before practice, there are 648 ounces of sports drink in the cooler, as the y-intercept of the equation is 648.

Statement C is not true: The coefficient of x, -24, does not represent the amount of sports drink each player is expected to drink. It represents the rate at which the amount of sports drink in the cooler decreases as players take drinks.

Statement D is not true: If no players take drinks from the cooler, x would be 0, and the amount of sports drink in the cooler after practice would be y = -24(0) + 648 = 648. However, this situation is not realistic, as players would normally take drinks from the cooler during practice.

Statement A is not true: The equation does not limit the number of players who can use the cooler. The equation only models the rate at which the amount of sports drink in the cooler decreases as players take drinks.

B.
In mx+b, b is initial value meaning they started with 648 ounces

A wallet contains 23 bills. All the bills are $1 bills and $5 bills. There are 7 more $1 bills than $5 bills. How much money does the wallet contain?

Answers

Answer:

Step-by-step explanation:

Let's say x is the number of $1 bills and y is the number of $5 bills. We know that:

x + y = 23

x = y + 7

We can use rearrange the second equation and add them together to find x. Then, we can plug x into any one of our equations to find y and calculate how much money is in the wallet.

x + y = 23

x - y = 7

2x = 30

x = 15 $1 bills

15 = y + 7

y = 8 $5 bills

15 * $1 + 8 * $5 = $15 + $40 = $55

We know that helium (He) will act more like neon (Ne) than beryllium (Be) Why is helium different than other elements with two valence electrons? Society and Solitude (excerpt I)Ralph Waldo Emerson1Tis hard to mesmerize ourselves, to whip our own top; but through sympathy we are capable of energy and endurance. Concert fires people to a certain fury of performance they can rarely reach alone. Here is the use of society: it is so easy with the great to be great; so easy to come up to an existing standard;as easy as it is to the lover to swim to his maiden through waves so grim before. The benefits of affection are immense; and the one event which never loses its romance, is the encounter with superior persons on terms allowing the happiest intercourse.2It by no means follows that we are not fit for society, because soires are tedious, and because the soire finds us tedious. A backwoodsman, who had been sent to the university, told me that, when he heard the best-bred young men at the law school talk together, he reckoned himself a boor; but whenever he caught them apart, and had one to himself alone, then they were the boors, and he the better man. And if we recall the rare hours when we encountered the best persons, we then found ourselves, and then first society seemed to exist. That was society, though in the transom of a brig, or on the Florida Keys.3A cold, sluggish blood thinks it has not facts enough to the purpose, and must decline its turn in the conversation. But they who speak have no more,have less. Tis not new facts that avail, but the heat to dissolve everybodys facts. The capital defect of cold, arid natures is the want of animal spirits. They seem a power incredible, as if God should raise the dead. The recluse witnesses what others perform by their aid, with a kind of fear. It is as much out of his possibility as the prowess of Cur-de-Lion, or an Irishmans days-work on the railroad.4Tis said, the present and the future are always rivals. Animal spirits constitute the power of the present, and their feats are like the structure of a pyramid. Their result is a lord, a general, or a boon companion. Before these, what a base mendicant is Memory with his leathern badge! But this genial heat is latent in all constitutions, and is disengaged only by the friction of society. As Bacon said of manners, To obtain them, it only needs not to despise them, so we say of animal spirits, that they are the spontaneous product of health and of a social habit. For behavior, men learn it, as they take diseases, one of another.5But the people are to be taken in very small doses. If solitude is proud, so is society vulgar. In society, high advantages are set down to the individual as disqualifications. We sink as easily as we rise, through sympathy. So many men whom I know are degraded by their sympathies, their native aims being high enough, but their relation all too tender to the gross people about them. Men cannot afford to live together by their merits, and they adjust themselves by their demerits,by their love of gossip, or by sheer tolerance and animal good-nature. They untune and dissipate the brave aspirant.QuestionAccording to the author, how does one develop an animal spirit?ResponsesA through intense meditationB through vigorous exerciseC through health and societyD through joy and sorrowE through authority guidance when the response requirements of an emergency event exceeds the capabilities of established emergency services in one or more critical areas, the event is classified as a Which expression does not have the same value as 2+365 ?
