If a takes person A 11 minutes, person B 21 minutes, and person C 33 minutes to complete the same task individually, then how long would it take if they work together? Estimate your answer to two places after the decimal, if necessary.
Answers
Answer:
5.92 min
Step-by-step explanation:
1/11 = person A's rate
1/21 = person B's rate
1/33 = person C's rate
Let t = time working to gether
rt = am't of work done
(1/11)t = work done by person A
(1/21)t = work done by person B
(1/33)t = work done by person C
(1/11)t + (1/21)t + (1/33)t = 1
231((1/11)t + 231(1/21)t + 231(1/33)t = 231
21t + 11t + 7t = 231
39t = 231
t = 5.92 min
I did that in super detail for you. Note: If n = the time to do a job alone, then 1/n = the rate of speed in doing the job. And, the rate times the time on the job = am't of work done.

I remember this from a while ago. they had us memorize a bunch of useless formulas which I still seem to remember the formula is:

volume divided by pi*height. then you square root all of that

Lin solved the equation 8( x - 3 ) + 7 = 2x( 4 - 17 ) incorrectly.
Find the errors in her solution. What should her answer have been?
Lin's solution:
8( x - 3 ) + 7 = 2x( 4 - 17 )
8( x - 3 ) + 7 = 2x(13 )
8x - 24 + 7 = 26x
8x - 17 = 26x
-17 = 34x
-½ = x
Answers
8( x - 3 ) + 7 = 2x( 4 - 17 )
Let’s condense as she did
8( x - 3 ) + 7 = 2x ( -13 )
Distribute
8x - 24 + 7 = -26x
Combine like terms
8x - 17 = -26x
Move x to one side
-17 = -34x
Divide by -34
1/2 = x
Lin had subtracted 4 - 17 incorrectly, having the number 13 as a positive instead of a negative number. Her answer should have been 1/2 instead of -1/2.

Find the first, fourth, and tenth terms of the arithmetic sequence described by the given rule.
A(n)=6+(n-1)(1/5)
Answers
Answer: a’(n)=1/5
Step-by-step explanation:
The first term is 6, the fourth term is 6.6, and the tenth term is 7.8 in the arithmetic sequence.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The given rule for the arithmetic sequence is:
A(n) = 6 + (n - 1)(1/5)
To find the first term, substitute n = 1 in the formula:
A(1) = 6 + (1 - 1)(1/5)
A(1) = 6 + 0
A(1) = 6
Therefore, the first term of the arithmetic sequence is 6.
To find the fourth term, substitute n = 4 in the formula:
A(4) = 6 + (4 - 1)(1/5)
A(4) = 6 + 3/5
A(4) = 6.6
Therefore, the fourth term of the arithmetic sequence is 6.6.
To find the tenth term, substitute n = 10 in the formula:
A(10) = 6 + (10 - 1)(1/5)
A(10) = 6 + 9/5
A(10) = 7.8
Therefore, the tenth term of the arithmetic sequence is 7.8.

Answers
Did you ever get the answer?
I did mine but i don’t know if it’s correct (I haven’t submitted it yet)
Area = 1/2 * base * height
Base= b = 20
Height = BD = 9.05
Area = 1/2 * 20 * 9.05
Area = 90.5 units squared
The expression for the area of ΔABC will be A = 1/2 x CA x BD, and the area is 90.5 square units.
What is the area of the triangle?The area of the triangle is given as
A = 1/2 x B x H
Where B is the base and H is the height of the triangle.
Then the expression for the area of ΔABC will be
A = 1/2 x CA x BD
A = 1/2 x 20 x 9.05
A = 90.5 square units

What is the area of the square?
What’s the area of the circle
Answers
Answer:
Square: 144 m²
Circle: 113.04 m²
Step-by-step explanation:
The formula for area of a square: side × side.
The formula for area of a circle: r²π (radius × radius × pi)
**SQUARES HAVE EQUAL SIDES**
As shown in the photo, the side lengths of the square are 12.
side × side
12 × 12 = 144
Therefore, 144 m² is the area of the square.
-------------------------------------------------------------------------------------------------------------
The diameter of the circle is 12 as well.
But, to find the area of the circle, we need the radius.
To find the radius of a circle, divide the diameter by 2.
12 ÷ 2 = 6.
6 is the radius.
Now we plug the numbers into the equation.
**3.14 IS A SUBSTITUTE FOR PI**
r²π (radius × radius × pi)
6²π (6 × 6 × 3.14) = 113.04
Therefore, 113.04 m² is the area of the circle.

Step-by-step explanation:
Let the Triangle be ABC
By Pythagoras Theorem:
(BC)² = (AB)² + (AC)²
(BC)² = 13² + 29.25²
(BC)² = 169 + 855.5625
(BC)² = 1024.5625
BC = √1024.5625
BC = 32.0087878558
