0.0008235 in scientific notation

Answers

Answer 1

Answer: Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
So, we're gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.

Answer 2

Answer:

Answer: the actual answer would be 8.235 x 10^-4

Step-by-step explanation:

bc you move it 4 places not 3

An office building casts a 90 foot shadow. At the same time of day, a 5 foot woman standing near the building casts an 8 foot shadow. What is the approximate height of the building to the nearest foot?A) 40 feet
B) 49 feet
Eliminate
C) 56 feet
D) 63 feet

Answers

I think it would be C) 56 feet. See, if we take the height of the woman(5) over the shadow she casts(8), and crossmultipy it with the height of the building(?) over the shadow of the building(90), it would be approximately 56 feet. 5/8 ?/90 90x5= 450 450/8= 56.25

Let \( A \) and \( B \) be events with \( P(A)=1 / 3 \) and \( P(B)=2 / 3 \). Let \( N \) be the number of events from among \( A \) and \( B \) that occur. (For instance, if \( A \) occurs but \( B \) does not, then \( N=1 \).) Suppose that the occurrence of events in \( A \) and \( B \) are independent. Find, for example, the probability that no events occur.

Answers

Answer:

( 2/9 )

Step-by-step explanation:

Okay, so since the events A and B are independent, the probability that both of them do not occur is the product of their individual probabilities of not occurring.

The probability of event A not occurring, denoted as ( P(A') ), is equal to 1 minus the probability of A occurring. Similarly, the probability of event B not occurring, denoted as ( P(B') ), is equal to 1 minus the probability of B occurring.

So, ( P(A') = 1 - P(A) = 1 - 1/3 = 2/3 ) and ( P(B') = 1 - P(B) = 1 - 2/3 = 1/3 ).

Since A and B are independent, the probability that both A and B do not occur is simply the product of their individual probabilities of not occurring:

[ P(N = 0) = P(A' cap B') = P(A')P(B') = (2/3) times (1/3) = 2/9 ]

So, the probability that no events occur is ( 2/9 ).

Hope this helps! :)

A surface area of a cube is 96cm. What is the length of one side? What is its volume

Answers

You are giventhe surface area of the cube which is 96cm2. You are asked to find the lengthof one side and its volume. Note that the surface area of the cube is equal to6 times the square root of s (the side of the cube) and the volume is the cuberoot of s. So,

SA = 6*s^2
96cm2 = 6*s^2
s^2 = 16cm
s = 4cm,this is the length of one side.

V = s^3
V = (4)^3
V = 64cm3,this is the volume of the cube.

12, 96/8 equals 12, so therefore it is 12 cm cubed

Step-by-step explanation:

Plug in: a^+b^2=c^2

a^2+12^2=18^2

a^2+144=324

subtract 144 from both sides

a=√180

a= 5√6
