How can you use powers and exponents to express known quantities

Answers

Answer 1

The most common ways is to indicate orders of magnitude through multiplying by powers of 10. I expect you’re at least seen something like 6.022∗1023

show up in your texts. The important part for this discussion is 1023

, because it gives us an idea of just how large this value is. If we wrote it all out, it would be: 602,200,000,000,000,000,000,000. You can do the same thing in the other direction, too. 10−28
Common value for certain types of physics, but a very, very small one.

Alternately, when dealing with probability, the function for determining the probability of series of independent events with the same odds is

where p is the probability of a certain outcome and n is the number of times the event occurs. For example, if we want to know what the odds of getting five heads in a row while flipping a coin we’re looking at 125
or 132

But the thing with powers of 10 is the most common I’ve seen, it even occasionally gets named Scientific Notation.

Answer:

Time, t = 9.615 secs.

Explanation:

Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.

Mathematically, speed is given by the equation;

[tex]Speed = \frac{distance}{time}[/tex] ....equation 1

[tex]Time = \frac{distance}{speed}[/tex] .....equation 2

Given the following data;

Distance = 100m

Speed = 10.4m/s

Substituting into equation 2;

[tex]Time = \frac{100}{10.4}[/tex]

Time, t = 9.615 secs.

A students wants to help her mother in their family store in displaying canned goods. Her mother instructed that the canned should be piled in triangular pile by starting 40 canned goods in the bottom row, 36 in the second row, 32 in the third row, and so on. If the pattern is consistent, how many canned goods will be there in the 7th row?

Answers

Answer: The number of canned goods in 7th row = 64.

Step-by-step explanation:

The given numbers of canned goods in every row( starting from first ) is represented as

40 , 36, 32, ...

There is a common difference between numbers(d)= 4

∴ Its is an Arithmetic progression.

First term (a) = 40

nth term in A.P. : [tex]a(n)= a+(n-1)d[/tex]

7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64

So, the number of canned goods in 7th row = 64.

2p + 3 = 5 - 6p
what is the value of p in the equation?

Answers

Answer:

p=1/4

Step-by-step explanation:

original: 2p+3=5-6p

move variable to one side: 2p+6p=5-3

combine like terms: 8p=2

answer :p=2/8

simplify answer (final answer): p=1/4

2p+3=5-6p

2p+6p+3=5

2p+6p=5-3

8p=5-3

8p=2

Answer: p=1/4

S =4LW + 2WH; S = 96, L= 7, W= 3.
H=

Help please

Answers

Answer:

H = 2

Step-by-step explanation:

Order of Operations: BPEMDAS

Step 1: Define

S = 4LW + 2WH

S = 96

L = 7

W = 3

Step 2: Substitute and Evaluate for H

96 = 4(7)(3) + 2(3)H

96 = 84 + 6H

12 = 6H

H = 2

Answer:

H = = 2 H W + 4 L W

Step-by-step explanation:

Substitute the given value into the function and evaluate.

S = 4 L W + 2 W H = = 2 H W + 4 L W

S = 96 = = 2 H W + 4 L W

L = 7 = = 2 H W + 4 L W

W = 3 = = 2 H W + 4 L W

H = = 2 H W + 4 L W

5+4(8n-8)=-1+6 for n

Answers

Answer:

n=1

Step-by-step explanation:

5+4(8n-8)=-1+6

5+32n-32=5

-27+32n=5

32n=32

n=1

Answer:

n = 1

Step-by-step explanation:

5 + 4(8n - 8) = -1 + 6

First you have to distribute the 4 leaving the equation to look like this...

5 + 32n - 32 = -1 + 6

Now solve the constants (normal numbers without a variable)

-27 +32n = 5

+27 +27 You have to add 27 to BOTH sides

32n = 32

n = 1
