Change .00025 to scientific notation

Mathematics
1 answer:
vekshin13 years ago
3 0
After you realize that
  0.00025 = 2.5·10^-4
    = 250·10^-6 or 250 μ
    = 250,000·10^-9 or 250,000 n
then it becomes a matter of semantics. Both A and D are correct representations, so choice B is incorrect.

Choice C present a dilemma. If you say it is correct, then there are 3 correct choices (A, C, D), not two, so C is incorrect.

If you say it is incorrect, then there are two correct answers (A, D), making choice C correct.

I'd probably choose C and try to avoid the argument with my teacher.

What is the interquartile range of the data set? Enter the answer in the box. Key: 1|5 means 15
Aneli [31]
First of all we have to arrange the data in ascending order as shown below:

28, 40, 43, 43, 45, 50, 50

Total number of values = 7

Since the number of values is odd, the median will be the middle value i.e. 4th value which is 43. Median divides the data in two halves:

1st Half = 28, 40, 43
2nd Half = 45, 50, 50

Q1 or the First Quartile is the middle value of the lower or 1st half which is 40.
Q3 or the Third Quartile is the middle value of the upper or second half, which is 50.

IQR or the Inter Quartile Range is the difference of Q3 and Q1.

So, IQR= Q3 – Q1 = 50 – 40 = 10

Thus, IQR for the given data is 10

Juan bought fruit from the grocery store. The variables below define his purchase. Juan’s bananas cost half as much as apples. W
mixas84 [53]

Answer:

B = \frac{1}{2}A

A = 2B

Step-by-step explanation:

Given

Represent apple with A and Banana with B

Required

Determine the relationship between A and B

From the question, we understand that:

B costs half as much as A

This can be represented as:

B = \frac{1}{2} * A

B = \frac{1}{2}A

Multiply both sides by 2

2*B = \frac{1}{2}A*2

2B = A

A = 2B

What is the answer to <br>2x+3=4x+6-(2x+3)
Grace [21]

I am still learning, and am most likely incorrect.

I believe you remove the 3's since their not needed, and do this:

2x = 4x + 6 - (2x)

so then just ignore "x" and do this:

2 = 4 + 6 - 2

2 = 10 - 2

2 = 8


x = 8

BRAINLIEST. NEED HELP NOW!!!<br> What is the value of x?
Arturiano [62]

Answer:

x=10

Step-by-step explanation:

these are similar triangles

8             12

------   = -----------

x+4          2x+1


using cross products

8* (2x+1) = 12(x+4)

distribute

16x + 8 = 12x+48

subtract 12x from each side

16x-12x +8 = 12x-12x+48

4x+8 = 48

subtract 8 from each side

4x+8-8 = 48-8

4x = 40

divide by 4

4x/4 = 40/x

x =10
