Converting between scientific notation and standard form in a real-world situation

Mathematics
1 answer:
Lisa [10]1 year ago
4 0

Answer:

\begin{gathered} a)9.54\times10^6\text{square miles} \\ b)0.0061\sec onds_{} \end{gathered}

Explanations:

a) The scientific notation is generally expressed as;

A\times10^n

A is any real numbers between 1 and 10

n is an integer

Given that the total surface area of North America is 9,540,000 square miles. This is expressed in scientific form as;

9,540,000=9.54\times10^6mi^2

From the scientific notation, A = 9.54 and n = 6

b) Given the scientific notation as shown:

6.1\times10^{-3}\text{seconds}

Writing in standard form means writing in the normal way we write numbers/decimals. Hence;

6.1\times10^{-3}=0.0061\text{seconds}

In parallelogram HJKL if HM=12 find HK.<br> K<br> M<br> M<br> H<br> L
Anestetic [448]

Answer:

HK = 24

Step-by-step explanation:

HK and JL are diagonals of the parallelogram.

Recall that diagonals of a parallelogram bisect each other. This implies that, they divide each other into equal parts.

Therefore,

HK = 2(HM)

HM = 12

Thus,

HK = 2(12)

HK = 24

If an item that originally cost $13 is increased to $19, what is the percentage of increase in the item?
Evgesh-ka [11]
Original cost (OC) = $13

New cost (NC) = $19

Percentage increase = \frac{NC - OC}{OC} *100 =  \frac{19 - 13}{13} * 100 =  \frac{6}{13} * 100

= 46.15 %

Find the x- and y-intercept of the line x+4y=36
blagie [28]

Answer:

x=36

y=9

Step-by-step explanation:

Plug in 0 for x to find the y-intercept

0 + 4y = 36

4y = 36

y = 9

y-intercept (0, 9)

Plug in 0 for y to find the x-intercept

x + 4(0) = 36

x = 36

x-intercept (36, 0)
