======================================================

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.

Step-by-step explanation:

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:

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.

Answer:

9%

Step-by-step explanation:15% of 60 is 9%

Answer:

25%

Step-by-step explanation:

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

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]

144 divided by 3 = d (number of days)

Step-by-step explanation:

Answer:

Equation: 3d=144

Solution: 48 days

Step-by-step explanation:

Since it grown 3 in. per day and it grew 144 in.

U have to divide the 2 numbers

3d=144

d=144/3

d=48 days

(d=how many days)

Any number to the power of 1 equals the number itself

Answer:

2

Step-by-step explanation:

2 ^1 is the same as saying multiplying 2 one time. 1x2 =2. Another example would be 2^2. You would multiply 2 by 2 twice, so two 2s.

Answer:

In basic mathematics, pi is used to find the area and circumference of a circle. Pi is used to find area by multiplying the radius squared times pi. So, in trying to find the area of a circle with a radius of 3 centimeters, π32 = 28.27 cm.

Answer:

Succinctly, pi or π is the ratio of the circumference of any circle to the diameter of that circle.

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
