Math Question. Help me Please

Answers

Answer:

Step-by-step explanation:

The answer to the question is c

Can anyone solve this?

Answers

Answer:

324 inches squared

Step-by-step explanation:

The question is most likely asking for the surface area of the rectangular prism.

The Formula for this is:

2(wl+hl+hw)

h = 6in

w = 5in

l = 12in

Plug in the varibles:

2( 5*12 + 6*12 + 6*5)

Simplify:

2( 60 + 72 + 30) =

2(162) =

324

So the answer is 324 inches squared!

Hope this helps! :)

Answer:

The surface area of the rectangular prism is: 324

The volume of the rectangular prism is: 360

Step-by-step explanation:

Surface area is calculated with the formula:

2(wl + hl + hw)

w*l = 6*12 = 72

h*l = 5*12 = 60

h*w = 5*6 = 30

Now add up 72, 60, and 30.

72+60+30 = 162.

This leaves us with the equation:

2(162)

So, we multiply 2 and 162 to get the surface area.

2*162 = 324.

For the volume, we multiply the length, width, and height altogther.

l*w*h

So, we plug in the values, and multiply:

12*6*5 = 360

The volume is 360 in^3

Stephanie is helping her band collect money to fund a field trip.
The band decided to sell boxes of chocolate bars. Each bar sells
for $1.50 and each box contains 20 bars. Below is a partial table
of monies collected for different numbers of boxes sold.
Boxes Sold (b) Money Collected (m)
1 $30
2 $60
3 $90
4 $120
5 $150
6 $180
7 $210
8 $240

1.) Complete the table above for all values of m.

2.) Which is the independent variable?

3.) Which is the dependent variable?

4.) Write an equation for the amount of money, m, that will be
collected if b boxes of chocolate bars are sold.

5.) Graph the equation using the ordered pairs from the table
above.
(Don’t forget to label your axes and increments!)

6.) How much money will be collected if 100 boxes of chocolate
bars are sold?

7.) The band collected $1530 from chocolate bar sales. How
many boxes did they sell?

Answers

Answer:

O P=20($1.50)

They will make $3,000 if they sell 100 boxes of chocolates

Step-by-step explanation:

It is multiplication because it is $1.50 per each chocolate bar, and since there is 20 per box, we need to find the profit for the entire box

using that info, we find that each box of chocolates is 30 dollars

multiplied by 100 boxes is $3000.

HELP! 6th-grade math PLEASE HELP!

Answers

first, find the area of prism ll by multiplying 5/2, 9/4, and 2

this will result in 45/4, or 11.25

now, you have to figure out how many small cubes will fit inside prism ll

we know that the side lengths of the small cubes are 1/4, and since cubes have equal side lengths, you can multiply 1/4, 1/4, and 1/4 to find the area

this will result in 1/64

divide the area of prism ll, 11.25, by the area of the small cubes, 1/64, to get 720

then, do the same thing for prism l

multiply 7/4, 3/2, and 5/4 to get 105/32

divide this by the previous 1/64 to get 210

lastly, to determine how many more small cubes can fit into prism ll, subtract 210 from 720

720-210=510

final answer: 510 cubes

hope this helped!!

"MARJORIE."The clear call rang out, breaking the afternoon stillness of the ranch, but there was no response, and after waiting a moment Miss Graham gave her wheeled chair a gentle push, which sent it rolling smoothly across the porch of the ranch house, down the inclined plane, which served the purpose of steps, to the lawn. It was very hot, the sun was blazing down as only an Arizona sun can blaze, and not a breath of air was stirring. But Miss Graham was accustomed to the heat and the glare. She paused for a moment, gazing off over the vast prairie to the California mountains, nearly a hundred miles away. She generally paused on that same spot for one look, although the landscape was the only one she had seen in twelve years. Then she moved on again, across the lawn, now parched and dry from the long summer's heat, toward the stables and out-buildings. It was before the smallest of these out-buildings, a tiny log cabin, that she finally brought the chair to a standstill."Marjorie, are you there?"There was a sound of some one moving inside, and a girl of fourteen, with a book in her hand, appeared in the doorway. . . . At sight of the lady in the wheeled chair . . . Marjorie's face brightened, and she hurried forward, exclaiming remorsefully:"Oh, Aunt Jessie dear, did you come all this way by yourself? I'm so sorry. Do you want me to do something for you?""You needn't be sorry," said her aunt, smiling. "The exercise will do me good, and I am quite proud of being able to manage this chair so easily. I called you from the porch, but you didn't hear. Your mother and Juanita are busy in the kitchen making jam, and I wasn't of any use there, so I thought I would come and see what you were about. I felt pretty sure of finding you in the old playhouse.""Come in," said Marjorie, eagerly. "You haven't been in the playhouse in ages; not since I grew too big to invite you to "make-believe" tea, but the door is just wide enough for the chair; don't you remember? Let me help you in?" And springing to Miss Graham's side, Marjorie seized the handle of the chair, and carefully guided it through the narrow entrance, into the little house her father had built for her own special use, and which had always been known as the playhouse. It might still have been regarded as a playhouse, although its owner had grown too old to play there. A couple of battered dolls reposed upon a toy bedstead in one corner, and an array of china dishes, all more or less the worse for wear, adorned the shelves. Marjorie loved her few possessions dearly, and in a place where one's nearest neighbor lives five miles away, there are not many people on whom to bestow things which have ceased to be useful to one's self, and they are therefore likely to be preserved.
