Answer:4.94*10^5

Step-by-step explanation:

Step-by-step explanation:

Hello there! I think the answer is: 4.94 × 10^5

In scientific notation, you move the decimal point until you get a number between 1 and 10. Then you count the number of digits after.

My reasoning is below-

There are 3 zeros right of the number 494.

Therefore, I got the answer 4.94 x 10^5

Step-by-step explanation:

Answer:

[tex]y=2x-8[/tex]

Step-by-step explanation:

First, remember that perpendicular lines have opposite and reciprocal slopes to the original line. That means for this line, your slope will be 2 (flip the fraction and change the sign). So we have:

[tex]y=2x+b[/tex]

Next, plug in the point that it passes through in order to find the y-intercept (b).

[tex]4=2(6)+b[/tex]

[tex]4=12+b[/tex]

[tex]b=-8[/tex]

So your equation will be:

[tex]y=2x-8[/tex]

so multiply .75 by 12

Answer:

175 boxes

Step-by-step explanation:

There are a total of 954 students since each student will get two popsicles that would mean we need a total of 1,908 popsicles (954 * 2). Since each box contains 12 popsicles then we simply divide the total number of popsicles needed by the number of popsicles that fit in each box to find the total number of boxes.

1,908 / 12 = 159 boxes

Since there are 25 boxes per carton we divide 159 by 25

159 / 25 = 6.36

Now we see that we need at least 6.36 cartons of popsicles, but since we can't get 6.36 we would need to get 7 cartons which would bring a total of

7 * 25 = 175 boxes

Finally, we would end up with 175 boxes of popsicles which would be enough for all the students and have leftover for the teachers.

Answer:

Step-by-step explanation:

Given

Initial deposit (Principal)= $250

Rate = 2%

Time = 1year (annual interest)

Required

Amount after 1 year

First we need to calculate interest

Interest = PRT/100

Interest = 250*2*1/100

Interest 2.5 * 2

Interest = $5.0

Next is to calculate amount;

Amount = Principal + Interest

Amount = $250 + $5

Amount = $255

Hence the value of a savings account at the Owl Credit Union at Dundalk High School that has an initial  deposit of $250 and pays an annual interest rate of 2% is $255.

Amount = P + I

Value of savings account is $255

Given that:

Initial deposit = $250

Annual interest rate = 2% = 0.02

Find:

Equations represents value of savings account

Computation:

Equations represents value of savings account = P + PRT

Equations represents value of savings account = 250 + (250)(0.02)(1)

Equations represents value of savings account = 250 + 5

Equations represents value of savings account = $255

Since x=5 is a vertical line, there is no y-intercept and the slope is undefined.

Answer:

A

Step-by-step explanation:

Answer:

x = 7

Step-by-step explanation:

You minus 8 from both sides which becomes, 5x = 35,

35 ÷ 8 = 7

Check work:

5 times 7 = 35.

35 + 8 = 43

The solution is: solve of the equation 5x + 8 = 43 is:  x = 7.

Here, we have,

given that,

the equation is: 5x + 8 = 43

now, we have to solve this.

so, we have,

5x + 8 = 43

we minus 8 from both sides which becomes,

5x = 35

we know that, 5 times 7 = 35

Divide 5 on both sides so that the only thing remaining on the left side is the variable x.

so, x = 7

Final Answer: 7

Hence, The solution is: solve of the equation 5x + 8 = 43 is:  x =7.

Answer:

The smallest possible value of the divisor is 19

Step-by-step explanation:

The given numbers for division are;

3759 and 4139, the remainder = 16

Let x represent the number

Therefore, we have;

x > 16

x is a factor of 3759 - 16 = 3743, and x is also a factor of 4139 - 16 = 4123

The factors of 3743 obtained from an online resource are 1, 19, 197, 3759

The factors of 4123 obtained from an online resource are 1, 7, 19, 31, 133, 217, 589, 4123

The common factors of 3743 and 4123 are 1, 19

Given that x > 16, we have, x = 19

Therefore, the smallest possible value that will divide both 3759 and 4139 whereby the remainder is 16 = 19
