C. 5^28
D. 5^11
Answer:
Option D
Step-by-step explanation:
If the bases are the same in a multiplication problem, then you can simply add the exponents. (i.e., a² × a⁶ = a²⁺⁶ = a⁸)
[tex]\bullet \rightarrow 5^4\times5^7[/tex]
[tex]\bullet\rightarrow 5^{4 + 7}[/tex]
[tex]\bullet \rightarrow \boxed{5^{11}}[/tex]
Answer: D
Step-by-step explanation:
5^4 x 5^7
You will add the exponent 4 + 7 = 11
You will keep your base 5^11

O 1/9
O 2/3
Answer:
1/9
Step-by-step explanation:
Given:
2 red marbles
4 white marbles
3 purple marbles
He will randomly select 2 marbles from the bag one at a time without
replacement.
To Find:
What is the probability that he will choose a red marble first and then a white marble?
Solution:
Since red marbles =2
White = 4
Total = 2+4+3 = 9
Select first time = 2/9
Select second time = 4/8
And then = Multiply
2/9 * 4/8 = 8/72
8/72 Simplify

Suppose if, instead of depositing the $600 all at once, you deposit nothing at the beginning and you divide up the $600 into 12 envelopes each with $50. Find the balance after one year if you deposit one $50 envelope each month, all year, into an account that pays 5% APR with monthly compounding.
The balance after one year if you deposit one $50 envelope each month, all year is $613.95.
What is the balance after one year?The balance after 1 year can be determined using this formula:
Amount deposited monthly x annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = interest rate = 5% /12 = 0.417%n = number of years = 1 x 12 = 12Annuity factor = 1.004167^12 - 1 / 0.00417 = 12.279082
Balance = 12.279082 x 50 = $613.95

What is the sum of the following equation?
three tenths plus thirty nine hundredths equals blank
Answer:
Step-by-step explanation:
Writing out the word question in numbers: three tenths plus thirty nine hundredths equals blank -
3/10 + 39/100 = ?
= 30/100 + 39/100
= 69/100
or 0.69 or sixty nine hundredths.
First convert words to no
three tenths=3/10thirty nine hundreds=39/100find sum
3/10+39/10030+39/10069/1000.69Identify the correct weight to the nearest 1/8 pound, then reduce the fraction if possible.
A. 2 12/16 = 2 3/4 Ib
B. 2 2/8 = 2 1/4 Ib
C. 2 14/16 = 2 7/8 Ib
D. 2 1/2 Ib
The measured weight is (2 + 3/4) lb, so the correct option is A.
How to read the measure?
First, we can see that the needle is between the 2lb and 3lb mark, so we know that we have a measure between these two values.
Now, let's count the number of small lines between the needle and the 2lb mark. There are 12 marks (the 12th is below the needle). Then the measure will be:
(2 + 12/16) lb.
Now we want to simplify the fraction. If we divide both numerator and denominator by 4, we get:
12/16 = 3/4
Then the weight is:
(2 + 3/4) lb
Then the correct option is A.

Which of the following would describe Slope?
A Rise/Run
B The rate of change
C The steepness of a line
D All of the above
Answer:
Rise/Run (A)
Step-by-step explanation:
The slope of a line measures the steepness of the line. Most of you are probably familiar with associating slope with "rise over run". Rise means how many units you move up or down from point to point. On the graph that would be a change in the y values. Run means how far left or right you move from point to point.

how do you find the square root for 9cm
[tex]\rightarrow[/tex]Square root of 9 is a whole number that is multiplied by itself to get the original number. The actual value of square root of 9 is 3.
√9 = ±3
[tex]\rightarrow[/tex]If we square +3 or -3, the resulting value will be equal to 9.
[tex]\sf{(+3)^2 = 9}[/tex]
[tex]\sf{(-3)^2 = 9}[/tex]
How to find?:-[tex]\rightarrow[/tex]Number 9 is an odd number and not a prime number. Prime numbers have only two factors, 1 and the number itself. But as we know, 9 have three multiple factors, 1, 3 and 9 itself. Thus, we can write the number 9 in the form of multiple as;
[tex]\sf{1 × 9 = 9}[/tex][tex]\sf{3 × 3 = 9}[/tex][tex]\sf{9 × 1 = 9}[/tex][tex]\rightarrow[/tex]You know that number 9 is a multiple of 3 or when 3 is multiplied by itself, we get the number 9. Therefore, we can write the square root of 9 as;
➾[tex]\sf{\sqrt{9}}[/tex]
➾[tex]\sf{\sqrt{3×3}}[/tex]
➾[tex]\sf{\sqrt{3^2}}[/tex]
[tex]\rightarrow[/tex]The square cancels the square root of a number. Therefore, if we cancel the square root with a square in the above expression, we get,
