Answers

Where is the table ?

30 percent of the sixth-grade class said that they spend the most time communicating with friends. Option A is correct.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

The total number of students,

56+32+81+39+62=270

The number of students involved in communicating with friends is 81.

The percentage of the student involved in communicating with their friend,

=(81/270)×100

=30%

Thus, 30 percent of the sixth-grade class said that they spend the most time communicating with friends. Option A is correct.

At a local garden shop, a customer pays $48 for 5 gerber daisies and 4 lily-of-the-valleys. Another customer pays $58 for 4 gerber daisies and 6 lily-of-the-valleys. Part A: Write a system of equations you can use to find the cost x of one gerber daisy and the cost y of one lily-of-the-valley. Part B: Solve the system of equations. Show your work or explain your steps.

Answers

Answer:

A lily costs $7 and a geranium $4.

Step-by-step explanation:

From the question we can write two equations. let the number of lilies be l and the number of geraniums be g, then:

Multiply the first equation by 4 and the second by 5, the number of lilies in the other, gives:

192

290

Subtract the first equation from the second gives:

which dividing by 14 gives

Substituting the value

in the first equation gives:

Subtract 20 from both side gives:

divide by 5 gives

So, a lily costs $7 and a geranium costs $4.

Answer:A lily costs $7 and a geranium $4.

Step-by-step explanation:From the question we can write two equations. let the number of lilies be L and the number of geraniums be g, then:

5g+41=48

4g+6 L=58

Multiply the first equation by 4 and the second by 5, the number of lilies in the other, gives:

20g + 16 L=192

20g + 30 L=290

Subtract the first equation from the second gives:

14 L =98 which dividing by 14 gives L=7

Substituting the value L = 7

in the first equation gives:

5g + 28 = 48

Subtract 20 from both side gives:

5g = 20

divide by 5 gives

g = 4

So, a lily costs $7 and a geranium costs $4.

Find the area of the shape shown below plsss hurry I only have limited time

Answers

Answer: 32

Step-by-step explanation: so we can start by finding the two small ones at the bottom. so 2 times 2 is 4/2 is 2, 2 times 6 is 12/2 is 6. then we have a square in the middle that is 2 times 2 is 4. then to find the rest, we can add the 2, the 6, and because we know the bottom middle shape is a square, another two, so we end up with a line of 10 unites. then we can do 4 times 10 is 40/2 is 20. then we add all of our answers. so 20 plus 2 plus 4 plus 6 which is 32.

Answer:

Step-by-step explanation:

4*10 = 40/2 = 20

2*2 = 4/2= 2

2*2=4

6*2 = 12/2= 6

20+2+4+6 = 32

I love the earthAnd all the gifts of her so lavish hand:Sunshine and flowers, rivers and rushing winds,Thick branches swaying in a winter storm,And moonlight playing in a boat's wide wake;But more than these, and much, ah, how much more,I love the very human heart of man.Above me spreads the hot, blue mid-day sky,Far down the hillside lies the sleeping lakeLazily reflecting back the sun,And scarcely ruffled by the little breezeWhich wanders idly through the nodding ferns.The blue crest of the distant mountain, topsThe green crest of the hill on which I sit;And it is summer, glorious, deep-toned summer,The very crown of nature's changing yearWhen all her surging life is at its full.To me alone it is a time of pause,A void and silent space between two worlds,When inspiration lags, and feeling sleeps,Gathering strength for efforts yet to come.Review the lines in bold.
