2.) 2.4
3.) 240
4.) 10^4
5.) 10^5
6.) 10^13


___ x ___ times larger

Answers

Answer 1

Final answer:

The population of China is approximately 240 times larger than the population of the Marshall Islands. This is calculated by dividing China's population (1.446×[tex]10^9[/tex]) by the Marshall Islands' population (6.025×[tex]10^4[/tex]). (Option 3)

Explanation:

The question asks us to determine how many times larger China's population is compared to the population of the Marshall Islands. To find the answer, we divide the population of China by the population of Marshall Islands:

1.446×[tex]10^9[/tex] (China's population) ÷ 6.025×[tex]10^4[/tex] (Marshall Islands' population).

Carrying out this division, we get a result of approximately 240 times larger. Thus, the population of China is 240 times larger than that of the Marshall Islands.

If it takes about 20 minutes to grade a student paper how long in hours does it take to grade palers for a class of 25 people

Answers

20X25=500mins
500/60 (mins in a hour)=8.33 hours

Final answer:

It takes about 20 minutes to grade one student's paper, so for a class of 25 students, it would take a total of 500 minutes, which is approximately 8.33 hours to grade all the papers.

Explanation:

If it takes about 20 minutes to grade a student paper, to find out how long it takes to grade papers for a class of 25 students, we need to multiply the number of students by the time taken to grade each paper.

Step-by-Step Calculation:

Multiply the number of students (25) by the minutes per paper (20 minutes): 25 students * 20 minutes per student = 500 minutes.

Convert minutes to hours. Since there are 60 minutes in an hour, we'll divide the total minutes by 60: 500 minutes ÷ 60 minutes per hour = 8.33 hours.

Therefore, it takes approximately 8.33 hours to grade papers for a class of 25 students. Please note that this is an ideal situation without any breaks or interruptions accounted for.

The stage manager of a school play creates a rectangular acting area of 42 square yards. String lights will outline the acting area. To the nearest whole number, how many yards of string lights does the manager need to enclose this area?

Answers

In this item, we cannot be fully sure of the dimensions of the rectangle because we are not given its properties and the type. For the sake of showing the solution to this item, we assume the rectangle to be square such that the area can be calculated through the equation,
                    s² = 42
where s is the length of the side. From the equation, the value of the s is 6.48 yards. 

The perimeter of the rectangle is calculated through the equation,
                  P = 2L + 2W
Substituting the known values,
                P = 2(6.48) + 2(6.48)
                P = 25.92
Thus, answer is 25.92 yards. 

Harvey collects rare marbles. He has 112 marbles in his collection. If he uses Seven Trees to hold all of the marbles, how many marbles will he display on three trays? Is tray hold an equal number of marbles answers at brainly.com

Answers

three trays will hold 48 marbles because each treat will be able too hold 16 marbles.

Final answer:

Harvey has 112 marbles distributed equally across seven trays. Each tray holds 16 marbles, therefore, on three trays, Harvey will display a total of 48 marbles.

Explanation:

Harvey has 112 marbles in his collection and uses seven trays to hold all of the marbles. To find out how many marbles Harvey will display on three trays, we need to divide the total number of marbles by the total number of trays to find out how many marbles each tray holds.

First, divide 112 marbles by 7 trays to find out how many marbles go on each tray. The calculation is as follows:

112 marbles ÷ 7 trays = 16 marbles per tray

Now that we know each tray holds 16 marbles, to find out how many marbles are displayed on three trays, we multiple the number of marbles per tray by the number of trays:

16 marbles per tray × 3 trays = 48 marbles

Therefore, Harvey will display 48 marbles on three trays.

Use substitution. 2x + 3y = 5 4x - y = 17 Use linear combinations: 2x + 3y = 5 4x - y = 17

Answers

I'll help you get started. To use substitution on the first pair of equations, we want to solve for one of the variables in one of the two equations. It looks like it would be easiest to solve for y in the second equation:
[tex]4x-y=17[/tex]
[tex]4x=17+y[/tex]
[tex]4x-17=y[/tex]

Now we want to substitute this alternate version of y into the first equation:
[tex]2x+3(4x-17)=5[/tex].

I'll let you finish off that first one. The second problem asks to solve the two equations using linear combination. This means we want to add the two equations together and cancel out one of the variables. Again, it's easiest to cancel out the y since one is negative. First we want to take the second equation and multiply by 3 on both sides:
[tex]3(4x-y)=3(17)[/tex]
[tex]12x-3y=51[/tex]

Now we want to add both equations together. Add the left sides and the right sides on their respective sides of the equals sign:
[tex](2x+3y)+(12x-3y)=5+51[/tex]

You can finish that one as well. Your answers for both methods will be the same if you do everything right! Let me know if you have more questions

Sunny earns $12 per hour delivering cupcakes. She worked for x hours this week. Unfortunately, she was charged $15 for a late delivery on Tuesday. How much money did sunny earn this week?

Answers

Answer: [tex]12x-15[/tex]

Step-by-step explanation:

Given: Sunny earns $12 per hour delivering cupcakes. She worked for x hours this week.

The total earning for this week = [tex]12x[/tex]

Also, she was charged $15 for a late delivery on Tuesday.

It means, The total earning for this week =[tex]12x-15[/tex]

So if Sunny earns $12 per hour delivering cupcakes. She worked for x hours this week and was charged $15 for a late delivery on Tuesday then her earning for this week = 12x-15

Bella's score on a spelling test is a function of the number of hours she studies. Which expression represents Bella's score on a spelling test if she studies for 3 hours?

A. 3(score)
B. Score(3)
C. Score + 3
D. 3 - score

Answers

The correct answer is C

Answer:

B. Score(3)

Step-by-step explanation:

Given,

Bella's score on a spelling test is a function of the number of hours she studies.

Let x represents the number of hours and S represents her score after x hours,

Thus, her scoring after x hours = S( x )

If she studies for 3 hours,

Suppose you start with at least $82 in your savings account and deposit $32 each week. Write, solve, and graph an inequality to describe how much money, m, you have after 10 weeks, w.

Answers

32 x 10= 320 + 82=402

Answer:

m ≥ 82 + 32w

m ≥ 402

Step-by-step explanation:

Here, w represents the number of weeks and m represents the total amount in the account after w weeks,

The amount of money saved in each week = $ 32,

So, the total amount saved after weeks = 32w dollars,

Since, the original amount in the account = $ 82

The total amount in the account = 82 + 32w

Thus, the required inequality would be,

m ≥ 82 + 32w

If w = 10,

The amount in the account after 10 weeks = 82 + 32(10) = 82 + 320 = $ 402

⇒ m ≥ 402  

That is, the closed circle on 402 and shaded right in the number line ( shown below )

seven less than the quotient of a number, x, and twelve is five times the number. which answer represents this situation? x/12−7 5x 7−x/12=5x 7−x/12 5x x/12−7=5x

Answers

Quotient is basically the answer you get when you divide two numbers. For example, the quotient of 6 and 3 is 2 because when I divide 6 by 3, I get 2.

Quotient of a number x and 12 = [tex] \frac{x}{12} [/tex]

7 less than quotient of a number x and 12 = [tex]\frac{x}{12} - 7[/tex]

5 times the number = 5*x = 5x

Hence, the equation is;

[tex]\frac{x}{12} - 7 = 5x[/tex]

[tex] \frac{x-(7*12)}{12} = 5x[/tex]

[tex]x-84 = 5x*12[/tex]

[tex]x - 84 = 60x[/tex]

[tex]x - 60x = 84[/tex]

[tex]-59x = 84[/tex]

x = [tex] \frac{84}{-59} = - \frac{84}{59} [/tex]

= -1.423728813559322 ≈ 1.42

Solve the equation a+b-c=180 for c

Answers

We need to make sure c is on one side:

a + b - c = 180

So let’s subtract a and b from both sides:

-c = -a -b + 180

Now, multiply both sides by -1:

c = a + b - 180

Hope this helps!

Answer:

Step-by-step explanation:

we are given the equation a+b-c=180

Now to solve it for c we need to isolate the c

first step can be addition of c to  both side

a+b-c+c=180+c

a+b=180+c

now in second step we subtract 180 from both sides to get

a+b-180=180+c-180

a+b-180 = c

c= a+b-180

Then the storehouses were filled up once more with the tributes paid the Inca. If there came a lean year, the storehouses were opened and the provinces were lent what they needed in the way of supplies; then, in a year of abundance, they paid back all they had received. No one who was lazy or tried to live by the work of others was tolerated; everyone had to work. Thus on certain days each lord went to his lands and took the plow in hand and cultivated the earth, and did other things. Even the Incas themselves did this to set an example.
