Answers

Answer 1
8.25 * 10^3 = 8250


since ur exponent is positive, u move the decimal to the right...and since the exponent is 3, u move it 3 spaces to the right of ur decimal....8.25...moving the decimal 3 spaces to the right makes ur number 8250
examples :
2.3 * 10^5....move the decimal to the right 5 spaces, = 230000
5.67 * 10^4...move the decimal to the right 4 spaces, = 56700

now if ur number has a negative exponent, u would move ur decimal to the left.
2.3 * 10^-3....move ur decimal to the left 3 spaces, = 0.0023
5.467 * 10^-5....move the decimal 5 spaces to the left, = 0.00005467


Answer 2

Final answer:

To convert 8.25 × 10³ into an ordinary number, move the decimal point 3 places to the right, resulting in 8250. Similarly, for dividing powers of ten, subtract the exponents and divide the coefficients accordingly.

Explanation:

To convert 8.25 × 10³ to an ordinary number, you need to understand how powers of ten work in scientific notation. The exponent on the 10 indicates how many places to move the decimal point. Since the exponent is positive, you will move the decimal point to the right. For 8.25 × 10³, you move the decimal 3 places to the right, giving us 8250.

Now, addressing the division example of 2.4 × 10¹³ divided by 8 × 10⁷, we use the rule that when dividing powers of 10, we subtract the exponents. This gives us 10¹³/10⁷ = 10⁶ (13 minus 7 equals 6). Then we divide the coefficients (2.4 divided by 8 equals 0.3) to get the final answer of 0.3 × 10⁶, or 3 × 10⁵ when we adjust the coefficient to have a single digit before the decimal point.

how do you solve 7+1/4r=-17

Answers

7 + 1/4r = -17

We're very simply trying to solve for "r."

So, we need to isolate "r."

To do this, start by subtracting 7 from both sides.

1/4r = -17 - 7

Simplify.

1/4r = -24

Now, multiply both sides by 4.

1/4r × 4 = -24 × 4

Simplify.

x = -96

lenght of segment OP

Answers

I've never been good at math, but this is how I think it's supposed to be solved.

Since segment SQ is half of segment OP, it wouldn't be equal; instead, it'd be multiplied by 2 to equal to OP.

Multiply segment SQ by 2.

2(5x - 2) = 8x + 6

10x - 4 = 8x + 6

Add 4 to both sides.

10x = 8x +10 

Subtract 8x from both sides.

2x = 10 

Divide both sides by 2.

x = 5

Step-by-step explanation:

Hi, to answer this question we have to subtract the height difference (1/3 ) to the Older brother's height. (4 3/4).

Mathematically speaking:

4 3/4 -1/3 = (4x4+3)/4 -1/3 = 19/4 -1/3 = 57/12-4/12 = 53/12 feet

1. A room is in the shape of a rectangle. The width of the room is 2 feet longer than two thirds the length. If the room is 33 feet long, what is the area?

Answers

2/3 of 33 is 22
so 22 +2 = 24
so 24x33=792
so the area is 792

To calculate the area of the rectangular room with a length of 33 feet and width that is 2 feet longer than two thirds of its length, we first find the width to be 24 feet and then multiply it with the length to get the area of 792 square feet.

Calculating the Area of a Rectangle

The question involves finding the area of a rectangular room given the length and a relationship between the length and width. The room is 33 feet long and the width is stated to be 2 feet longer than two thirds of the length. First, we determine the width by using the length to find two thirds of it and then adding 2 feet:

Width = (2/3)
Length + 2Width = (2/3)
33 feet + 2Width = 22 feet + 2 feetWidth = 24 feet
Now that we have both dimensions, we calculate the area:Area = Length x WidthArea = 33 feet x 24 feetArea = 792 square feet
So, the area of the room is 792 square feet.

20 people................20 walls........1040:20=52 min

Answer:52 min

Step-by-step explanation:

Given

5 people paint 5 walls in 52 minutes

Now if 1 person paints the 5 walls then time required will be 5 times  more

1 Person paint 5 walls in [tex]52\times 5[/tex]

For 20 walls person has to do 4 times the previous  walls

1 person paints 20 walls in [tex]52\times 5\times 4[/tex]

Answers

Well all we have to do here is add and subtract.       Ryan's times    14.19 and 13.78      13.78 + 14.19 = 27.97 seconds            Daniel's times     15.77 and 16.24      15.77 + 16.24 = 32.01     Then all we have to do is subtract the 2 total times.       32.01 - 27.97 = 4.04 seconds.     Daniel's time was 4.04 seconds higher than Ryan's time.

Ryan runs 100 m two times. His times were 14.19 s and 13.78 s.

Daniel runs 100 m two times. His times were 15.77 s and 16.24 s.

The total time taken by Ryan will be

⇒ 14.19 + 13.78

⇒ 27.97 seconds

The total time taken by Daniel will be

⇒ 15.77 + 16.24

⇒ 32.01 seconds

The difference of the Daniel time to Ryan time will be

⇒ 32.01 – 27.97

⇒ 4.04 seconds

Daniel's total time is 4.04 second greater than Ryan's total time.

Which is greater -6.875 or -6.89...

Answers

-6.875 is greater because it is closer to zero (being positive). Think about it as the opposite way or positive numbers. If they were both positive, the answer would be 6.89, because they are greater than zero.
-6.89 is greater. because -6.875 is shorted to -6.87 so 6.89 is -0.02 bigger.

The whole string was 2.4m. If you take 1/3 of 1/2x, you are just taking 1/6x. You know that what remains is 2m, and that it's the remaining 5/6. So you divide 2 by 5 and multiply that by six to get 2.4.

Final answer:

Explanation:

The next 3 terms of the sequence 22, 21, 18, 13, and 6 can be found by analyzing the pattern in the sequence. The difference between each term is decreasing by 1 each time. So, the next difference would be 5 - 1 = 4. Subtracting 4 from 6 gives us 2. Therefore, the next term in the sequence is 2. Repeating this process, we can find the following terms: 2, -3, and -8.
