3^10 + 3^10 + 3^10=
a)9^30
b)3^30
c)9^10
d3^11
Answer:
As a^m+a^m+a^m=a^m+m+m or (a+a+a)^m {WHEN BASES ARE SAME WE CAN ADD THE BASES TOGETHER AND PUT THE POWER (IN CASE OF ADDITION) AND WHEN POWERS ARE SAME WE CAN ADD THE POWERS AND LET THE BASE REMAIN SAME}
So,
(3+3+3)^10 and 3^10+10+10 is also true (only because both the basesa nd the powers here are the same)
So,
9^10 and 3^30
So option b and c are correct
Beth and Pam both did some babysitting in the summer. Pam earned $4 less than 3 times as much as Beth. Together they earned $860. How much money did each person earn babysitting?
======================================================
Work Shown:
B = amount Beth earned
P = amount Pam earned
amounts are in dollars
Pam earned $4 less than 3 times as much as Beth, so,
P = 3B-4
Together they earned $860, meaning
P+B = 860
Plug the first equation into the second. Solve for B
P+B = 860
3B-4+B = 860
4B-4 = 860
4B = 860+4
4B = 864
B = 864/4
B = 216
Use this to find P
P = 3B-4
P = 3*216-4
P = 648-4
P = 644
Beth earned $216 and Pam earned $644.
----------------------------------------
Check:
B+P = 860
216+644 = 860
860 = 860
First equation is true
P = 3B-4
644 = 3*216-4
644 = 644
Second equation is true
Both equations are true when (B,P) = (216,644) so the solutions have been confirmed.

In Sam's drawer, there are 17 red socks, 13 green socks, and 20 black socks. Any two socks of the same color make a pair.
* If the first sock that Sam took out was black, how many more socks must he take out from the drawer without looking to be absolutely sure to have a pair of socks (of any color)?
Answer:
19:50
Step-by-step explanation:
well when you add all the socks you have 50 socks. if the first sock that Sam took out was black the second sock would be a ratio of 19:50.

In a certain city, three newspapers A, B, and C are published. Suppose that 60% of the families in the city subscribe to newspaper A, 40% of the families subscribe to newspaper B, and 30% subscribe to newspaper C. Suppose also that 20% of the families subscribe to both A and B, 10% subscribe to both A and C, 20% subscribe to both B and C, and 5% subscribe to all three newspapers. (i) What percentage of the families in the city subscribe to at least one of the three newspapers? (ii)What percentage of the families in the city subscribe to exactly one newspaper?
Answer:
(i) = 85%
(ii) = 30%
Step-by-step explanation:
The question is a probability question.
We will need the following values:
P(A) = 60%
P(B) = 40%
P(C) = 30%
P(AnB) = 20%
p(AnC) = 10%
P(BnC) = 20%
P(AnBnC) = 5%
(i) To determine the percentage of the families in the city that subscribe to at least one of the three newspapers:
P(A) + P(B) + P(C) + P(AnBnC) - P(AnB) - p(AnC) - P(BnC)
= 60% + 40% + 30% + 5% - 20% - 10% - 20%
= 85%
(ii) To determine the percentage of the families in the city that subscribe to exactly one newspaper:
P(at least one paper) - p(AnB) - p(AnC) - P(BnC) - P(AnBnC)
= 85% - 20% - 10% - 20% - 5%
= 30%

Answer:
25%
Step-by-step explanation:
Rafael writes an expression to represent “a number, n, decreased by thirty-one.” Then he evaluates that expression if n = 29. Which statements are true about the expression and its evaluation? Check all that apply.
The correct expression is 31 minus n.
This is a subtraction expression.
This is an addition expression.
To evaluate, substitute 29 for the variable in the expression.
To evaluate, substitute 31 for the variable in the equation.
To evaluate the expression, add 31 to 29.
The correct expression is n minus 31.
To evaluate the expression, subtract 31 from 29.
Please hurry I need this answer ASAP
Answer:
The correct alternatives
This is a subtraction expression
The correct expression is n minus 31
To evaluate the expression, subtract 31 from 29.
Step-by-step explanation:
Rafael writes an expression to represent “a number, n, decreased by thirty-one.”
First you gotta know what means "decreased by thirty-one". It means that
there exist two numbers where the difference between them is 31.
The number [tex]n[/tex] decreased by 31 can be writen as
[tex]n-31[/tex]
The expression is therefore
[tex]n-x=31 \implies \boxed{x=n-31}, n, m \in \mathbb{R}[/tex]
Rafael evaluates the expression [tex](n-31)[/tex] for [tex]n=29[/tex]
[tex]n-31 = 29-31 = -2[/tex]

Your class is selling boxes of flower seeds as a fundraiser. The total profit p depends on the amount x that your class charges for each box of seeds. The equation
p= -0.53 +25x - 120
models the profit of the fundraiser. What's the
smallest amount, in dollars, that you can charge and make a profit of at least $105?
Answer:
$9.03
If you want smallest amount it dollars, you have to go with $9. However, this will only give you a profit of $104.47
Step-by-step explanation:
p = -0.53 +25x - 120
105 = -0.53 +25x - 120
225.53 = 25x
x = 9.0212
Check work:
105 = -0.53 +25(9.02) - 120
105 ≠ 104.97
Since $9.02 doesn't equal $105 profit, let's add a penny to make it $9.03.
105 = -0.53 +25(9.03) - 120
105 ≠ 105.22
If you charge $9.03 for each box you will make a profit of at least $105.
Round to smallest amount in dollars:
105 = -0.53 +25(9) - 120
105 ≠ 104.47

PLEASE HELP!!!
Answer:
Ok:
Step-by-step explanation:
So f°g . means f(g(x)). (The ° should be more center and bigger but I don't know to do that on a keyboard). f(g(x)) means that you replace the x in f(x) with the g(x) function. i.e:
if f(x) = 2x+2
and g(x) = [tex]x^2[/tex]
f(g(x)) = [tex]2x^2+2[/tex].
Similarly, in this case, we get f(x) = 2x-3 and g(x) = 3x-2.
Then, f(g(x)) or f°g(x) is 2(3x-2) - 3.
And we plug in -2 to solve:
2(3(-2)-2)-3.
and get -19.
Check if I am wrong because everyone makes mistakes but that is the way to solve this.
