Explain how you can find 3x584 using expanded form

Answers

I believe what you need to do is multiply 3 by each number. 
To start, 3*584 is 1752. Expanded form written out would be (3*500)+(3*80)+(3*4). Simply multiply all the numbers and then add them together. 3*500=1,500; 3*80=240; 3*4=12. 1,500+240=1740+12=1752. Hope this helps! :)

Mrs. Synder must choose two of her homeroom students to be class representatives. The class consists of 13 girls and 9 boys. Approximately what percent chance is there that the first student chosen is a boy and the second student chosen is a girl? (Round to the nearest percent)

A. 10%

B. 25%

C. 22%

D. 15%

Answers

9/22 x 13/21 = 0.25 = 25% B

Answer:   B. 25%

Step-by-step explanation:

Given : Number of boys in the class = 13

Number of girls in the class = 9

Total students  = 13+9=22

Now, the number of ways to choose first boy then a girl =[tex]13\times9=117[/tex]     (1)

Number of ways to choose nay two students :-

[tex]{22}P_{2}=\dfrac{22!}{(22-2)!}\\\\=\dfrac{22\times21\times20!}{20!}=462[/tex]     (2)

Now, the probability that the first student chosen is a boy and the second student chosen is a girl :-

[tex]\dfrac{117}{462}=0.253246753247\approx0.25[/tex]   [Divide (1) by (2)]

In percent , [tex]0.25\times100=25\%[/tex]

Hence, approximately 25% chance that the first student chosen is a boy and the second student chosen is a girl.

Josh is 4 years older than Delaney. In 5 years the sum of their ages will be 60. How old is Josh now?

Answers

x + 5 + 4 + x + 5 = 60
2x + 14 = 60
-14 -14
2x = 46
x = 23

So, Josh's age is 23 + 4 which is 27 years old.

Final answer:

The problem is a middle school mathematics question about algebra and age. By setting up an equation and solving it, we found that Josh is currently 27 years old.

Explanation:

The subject of this question is Mathematics, and it is likely a Middle School level problem. To solve this, we set up an equation based on the information provided: Let's denote Delaney's current age as D. According to the question, Josh is 4 years older than Delaney, so Josh's current age is D + 4 years. In 5 years, Delaney will be D + 5 years old, and Josh will be (D + 4) + 5 which simplifies to D + 9 years old. We know that the sum of their ages in 5 years will be 60. Therefore, the equation is:

D + 5 + D + 9 = 60

Combining like terms, we get:

2D + 14 = 60

Subtracting 14 from both sides, we get:

2D = 46

Divide both sides by 2 to find Delaney's current age:

D = 23

Now, we can determine Josh's current age by adding 4:

Josh's age = D + 4 = 23 + 4 = 27

Therefore, Josh is currently 27 years old.

26-38+(-3) what is the answer.

Answers

So basically, first just do this step by step, or subtract 38 from 26 first.

26 - 38 is basically -(38 - 26), or -12.

So then, it becomes -12 + (-3)

A - and a + becomes - because you're adding negative 3.

-12 - 3

Which then becomes -15.
The answer to your question is -15

There are 300 apples and peaches for sale at a farmer's market. The ratio of the number of apples to the number of peaches is 7 : 8. If 50 apples and 40 peaches are sold, what is the ratio of the remaining apples to peaches?

Answers

7:8.....added = 15

7/15(300) = 2100/15 = 140 apples
8/15(300) = 2400/15 = 160 peaches

if 50 apples and 40 peaches are sold....
apples : 140 - 50 = 90
peaches : 160 - 40 = 120

ratio of remaining is : 90/120 which reduces to 3/4 or 3:4 or 3 to 4 <==

One winter night the temperature fell 16 degrees between midnight and 5 A.M. By 9 A.M.the temperature had doubled from what it was at 5 A.M. By​ noon, it had risen another 12 degrees to 30 degrees. What was the temperature at​ midnight?

Answers

The temperature at midnight was 25 degrees.

We have at one winter night the temperature fell 16 degrees between midnight and 5 A.M. By 9 A.M. the temperature had doubled from what it was at 5 A.M. By​ noon, it had risen another 12 degrees to 30 degrees.

We have to determine the temperature at​ midnight?

What is Temperature ?

Degree of hotness or coldness measured on a definite scale is called Temperature. When the temperature of the body is high it is called hot body and when it is low it is called cold body.

According to the question -

Assume the temperature at mid - night be x and at 5 AM be y.

Then -

x - y = 16

At 9 A.M. , assume the temperature to be z. Then -

z = 2y

At Noon -

z + 12 = 30

z = 30 - 12

z = 18 degree

At 9 A.M., we have -

z = 2y

18 = 2y

y = 9 degrees

At mid - night, we have -

x - y = 16

x - 9 = 16

x = 25 degrees

Hence, the temperature at midnight was 25 degrees.

Which equation can be used to find one or more factors of 26

Answers

The factors of 26 are one, two, 13 and 26. One and the number itself, in this case 26, are always factors. Since 26 is an even number, which means that it ends in zero, two, four, six or eight, it's evenly divisible by two. Two times 13 equals 26.

No numbers between two and 13 divide evenly into 26, so there are no more factors other than the four listed. Because two and 13 are both prime numbers, which are numbers that are only divisible by one and themselves, the prime factorization of 26 is 2 x 13. The prime factorization of a number refers to the prime numbers that multiply together to make that given number
One equation could be x(y)=26

Can rational numbers be expressed as a fraction of two integers

Answers

Yes, this is what a rational number is.
Yes this is the exact definition of what it means to be a rational number. A rational number is one that is a fraction of two whole numbers (or integers). The denominator, or the number in the bottom of the fraction, cannot be 0.

Some examples:
7 = 7/1
2/3
8/10
0.5 (since this equals 1/2)
the square root of 64 (since it equals 8 = 8/1)
any repeating decimal
any terminating decimal

Non-examples are things like...
sqrt(7)
pi
log(3)
any decimal where there isn't a clear pattern that repeats

Since he gets 10$ per shirt, his revenue is 10y if y represents the shirts sold as he adds 10$ with every purchase. His expenses start with the base cost of 1500, then he also has to pay 3 dollars for each shirt, so his expenses add up to 1500+3y. Since he wants to make as much as he spent, his revenue has to equal his expenses and 10y=1500+3y. Subtracting 3y from both sides, we get 7y=1500. Dividing both sides by 7, we get y=214.something=215 by rounding up
the break even point is when ur expenses = ur revenue...there is no profit

1.  expenses (what it costs steve ) are 1500 plus x shirts for $ 3
     revenue(what steve makes from selling shirts) are x shirts for $ 10
     so ur 2 equations would be : y = 3x + 1500 and y = 10x

2. 3x + 1500 = 10x
    1500 = 10x - 3x
    1500 = 7x
     1500/7 = 214.28....so he would have to sell 215 shirts.

4.3t-2.1t-2.3=7.6
Solve equation

Answers

If your solving for t then t = 4.5 
Final answer:

The equation can be solved by combining like terms, isolating the variable t, then dividing by the coefficient of the variable. The solution to the equation is t = 4.5.

Explanation:

The given equation in this problem is 4.3t - 2.1t - 2.3 = 7.6. To solve the equation, first we need to combine like terms, meaning we would subtract 2.1t from 4.3t.

This leaves us with 2.2t - 2.3 = 7.6. After that, we must isolate t by adding 2.3 to both sides of the equation. This results in 2.2t = 9.9. Finally, we divide both sides by 2.2 to solve for t, which gives us t = 4.5.
