Q 06. Payson is thrice as fast as Amen at completing a task. They both pick up a task together, and complete it in 5 days. How many days will Amen take to do it alone? Ops: A. O 10 days B. O 20 days C. O 25 days D. O 15 days
Fraction are ratio of two integers. It will take Amen 20 days to do the task alone
Proporions and fractionsFrom the given question, we have the following information
Let the number of days Amen can take to complete a task be x
If Payson is thrice as fast as Amen at completing a task, then the number of das Payson takes will be 3x
If they both pick up a task together, and complete it in 5 days, then;
1/x + 1/3x = 1/5
Find the LCM
3+1/3x = 1/5
4/3x = 1/5
Cross multiply
3x = 20
Determine the time taken by Amen:
x =20/3
This shows that it will take Amen 20 days to do the task alone

In a golden rectangle, the sides of the rectangle are as per the golden ratio. The perimeter of the golden rectangle with a width of 15 feet is 79 feet.
What is a golden rectangle?In a golden rectangle, the sides of the rectangle are as per the golden ratio. The rectangle is given the name rectangle because of the fact that the ratio is the golden number 1.618.
In a golden rectangle, the sides of the rectangle are as per the golden ratio. Since the width of the rectangle is 15 feet, therefore, the length of the rectangle will be 1.618 times the width,
Length of the rectangle = 1.618 × 15 feet = 24.27 feet
Now, the perimeter of the rectangle can be written as,
[tex]\rm \text{Perimeter of the rectangle} = 2(Length+ Width) \\\\\text{Perimeter of the rectangle} = 2(24.27+15)\\\\\text{Perimeter of the rectangle} = 78.54 \approx 79\ feet[/tex]
Hence, the perimeter of the golden rectangle with a width of 15 feet is 79 feet.

Determine if x + 3 is a factor of -3x^3+6x^2+6x+9 How do you know
Answer:
x+3 is not a factor
Step-by-step explanation:
A graphing calculator shows the expression has a zero at x=3 and no other real zeros. If x+3 were a factor, there would be a zero at x = -3.
x+3 is not a factor of the expression.
_____
You can check to see if x+3 is a factor by evaluating the expression for x=-3. If (x+3) is a factor, x=-3 will make the function be zero.
3(-x³ +2x² +2x +3) = 3(((-x +2)x +2)x +3) = 3(((-(-3)+2)(-3) +2)(-3) +3)
= 3((-15+2)(-3) +3) = 3(39 +3) = 126 ≠ 0
The expression evaluates to 126 at x=-3, so x+3 is NOT a factor.

angles on a straight line add up to 180 degreesangles in a triangle add up to 180 degreesso.
because of rule 1, we do 180-120 to get 60, to get that right corner angle. Now, we know 2 angles. So, (because of rule 2), we can do 60+32 = 92, and 180-92 = 88

What is the power set of s={1,2,3,4,5}
The power set P(X) of a finite set X is the set of all possible subsets of X. If X has n elements, then it has a total of 2ⁿ subsets.

Explanation:
To find the area of the triangle we must us a formula which is base x height ÷ 2 divide. So on the left side it is 17 cm and on the right without the triangle it is 10 so the triangle is 7cm tall. Next on the bottom without the triangle it is 22 and with it is 12 so the base is 10 now we multiply them which will be 70 then divide it by 2 which is 35cm².

T = (324/34x).
How to get the expression?He does 18 laps in total.
8 laps at a rate of 3x10 laps at a rate of x.The average rate for the whole 18 laps is the average of the rates (taking in account the number of laps made with each) so we get:
average rate = (8/18)*3x + (10/18)*x = (34x/18)
This means that he does (34x/18) laps per hour.
Then, the time needed to do 18 laps is:

The table below shows the
values for the function y = f(x).
The answers are:
Second option, evaluating x=-1
[tex]g(-1)=-2[/tex]
Fifth option, evaluating x=6
[tex]g(6)=\frac{3}{2}[/tex]
Why?We are given a table that shows the values for the given function (f(x), and we are asked to find the solution of an equivalent function (g(x)).
We have that:
[tex]g(x)=\frac{1}{2}f(x)[/tex]
Now, evaluating we have:
For x=-3
[tex]g(-3)=\frac{1}{2}f(-3)=\frac{1}{2}*5=2.5[/tex]
We have the values (-3,2.5) so, it's not part of the solutions to the function g(x).
For x=-1
[tex]g(-1)=\frac{1}{2}f(-3)=\frac{1}{2}*-4=-2[/tex]
We have the values (-1,-2) so, it's part of the solutions to the function g(x).
For x=0
[tex]g(0)=\frac{1}{2}f(0)=\frac{1}{2}*2=1[/tex]
We have the values (0,1) so, it's not part of the solutions to the function g(x).
For x=5
[tex]g(5)=\frac{1}{2}f(5)=\frac{1}{2}*-8=-4[/tex]
We have the values (5,-8) so, it's not part of the solutions to the function g(x).
For x=6
[tex]g(6)=\frac{1}{2}f(6)=\frac{1}{2} *3=\frac{3}{2}[/tex]
We have the values [tex](6,\frac{3}{2})[/tex] so, it's part of the solutions to the function g(x).
Hence, we have that the answers are:
Second option, evaluating x=-1
[tex]g(-1)=-2[/tex]
Fifth option, evaluating x=6
[tex]g(6)=\frac{3}{2}[/tex]

Fill in the chart. (Round to the nearest penny)
=============================================================
Explanation:
If the money is compounded semiannually at a rate of 8%, then this means the multiplier (common ratio) is b = 1+r/n = 1+0.08/2 = 1.04
r = 0.08 = 8% annual interest raten = 2 = compounding twice a year, aka semiannually, aka every 6 months.In short, b = 1.04 is our growth multiplier. It says that the money is growing by 4% each 6 month period. Each time x goes up by 1, y increases by 4%. The starting amount is a = 2100 dollars.
We go from the template of [tex]y = ab^x[/tex] to [tex]y = 2100(1.04)^x[/tex]
Use that equation to fill out the table. For instance, if x = 2 then,
[tex]y = 2100(1.04)^x\\\\y = 2100(1.04)^2\\\\y = 2100(1.0816)\\\\y = 2271.36\\\\[/tex]
Meaning that after 2 semiannual periods (aka 2*6 = 12 months = 1 year), we'd have $2,271.36 in the account.
Repeat this for the other x values mentioned to get the table shown below. To fill out the final column of the first row, you'll look at the very bottom of the table in the previous column. Four semiannual periods is equal to 2 years.
--------------
These steps are repeated for the second row of the table.
This time the growth multiplier is b = 1 + r/n = 1 + 0.14/12 = 1.0116667 approximately. The starting amount is a = 700
So that's how we go from [tex]y = ab^x[/tex] to [tex]y = 700(1.0116667)^x[/tex]
Like before, you'd plug in the various x values to find their paired y counterparts.
Example:
Plug in x = 18
[tex]y = 700(1.0116667)^x\\\\y = 700(1.0116667)^{18}\\\\y = 700(1.2321801)\\\\y = 862.52607\\\\y = 862.53\\\\[/tex]
The values are approximate. After 18 months, aka 18/12 = 1.5 years = 1 yr + 6 months, we'd have about $862.53 in the account.

Convert the exponential to a logarithmic form: 10^4 = 10,000
Question 1 options:
A)
log 10 = 4
B)
log 4 = 10
C)
log 10,000 = 4
D)
log 4 = 10,000
Answer:
C
Step-by-step explanation:
Exponential form is y = b^x, with b as the base, and logarithmic form is x = log_b(y).
In this case, 10 is the base, 4 is x, and 10,000 is y. In logarithmic form, this can be changed into 4 = log_10(10,000). Logarithms with base 10 can also be written as 4 = log(10,000). Therefore C is the correct answer.

3/5 = 24/40 =?/60. what comes at the question mark?
Answer:
? = 36
Step-by-step explanation:
Knowing that 3/5 and 24/40 is equal
Therefore we can either use:
3/5 = ?/60 or 24/40 = ?/60
I will use 3/5 = ?/60
Let ? = x
Hence we have
3/5 = x/60
Multiply both sides by 10
6 = x/6
Multiply both sides by 6
x = 36
Therefore, the question mark = 36
Let's check the answer by Simplifying the fraction:
3/5 = 36/60
3/5 is in already simplify
36/60 simplify = 3/5
3/5 = 3/5
Thus, the question mark = 36
[RevyBreeze]
Step-by-step Solution:
Let the "?" be known as "x".
Given equation:
3/5 = 24/40 = x/60
Therefore, we obtain the following equations:
Equation 1: 3/5 = 24/40Equation 2: 3/5 = x/60Equation 3: 24/40 = x/60Clearly, the second and the third equation have the "x" variable included. Therefore, we will only focus on the second and third equations.
3/5 = x/6024/40 = x/60Note: We can choose any equation to solve for x. The value of x in both equations will be the same as 3/5 = 24/40.
Determining the "x" variable in Equation 2:
⇒ 3/5 = x/60⇒ 5x = 60 × 3 [Cross multiplication]⇒ 5x = 180 [Simplifying]⇒ 5x/5 = 180/5 [Dividing]⇒ x = 36 [Simplifying]Determining the "x" variable in Equation 3:
⇒ 24/40 = x/60⇒ 40x = 24 × 60 [Cross multiplication]⇒ 40x = 1440 [Simplifying]⇒ 40x/40 = 1440/40 [Dividing]⇒ x = 36 [Simplifying]Therefore, the value of "?" is 36.
