6 men and 10 women can finish making pots in 8 days, while the 4 men and 6 women can finish it in 12 days. Find the time taken by the one man alone from that of one woman alone to finish the work.
Answer:
48 days
Step-by-step explanation:
Let us assume the following things
Work done by 1 man in 1 day is [tex]\frac{1}{x}[/tex]
Work done by 1 woman in 1 day is [tex]\frac{1}{y}[/tex]
It is mentioned that
six men + ten women finished in 8 days
So,
[tex]\frac{6}{x} + \frac{10}{y} = \frac{1}{8}[/tex] .............. (1)
And,
four men + six women finished in 12 days
[tex]\frac{4}{x} + \frac{6}{y} = \frac{1}{12}[/tex] ...............(2)
Now solve these two equations
And we assume [tex]\frac{1}{x}[/tex] be u and [tex]\frac{1}{y}[/tex] be v
So
Now the equation is
[tex]6u\ + 10v\ = \frac{1}{8} \\\\\4u\ + 6v\ = \frac{1}{12}[/tex]
So,
u = 1 ÷ 48 , v = 0
Therefore x = 48
So the time taken for finish the work is 48 days
Jacob’s age is two years more than the sum of the ages of his siblings Becky and Micah. Which equation represents Jacob’s age?
A. z = x + y − 2; x represents Micah's age, y represents Becky's age, and z represents Jacob's age
B. x = y + z + 2; x represents Jacob's age, y represents Micah's age, and z represents Becky's age
C. x = 2 + y + z; x represents Becky's age, y represents Jacob's age, and z represents Micah's age
D. y = x + z − 2; x represents Jacob's age, y represents Becky's age, and z represents Micah's ag
Answer:
B.
Step-by-step explanation:
Hi! Here is the explanation!
When reading this question you need to make sure you know that sum and more than are words that can help to create equations. Jacob is 2 years older than becky and michas ages combined.
The equation would be:
y= 2+ (Becky's age+Micha's age)
I hope this helped!

What is the approximate circumference of the swimming pool? Use 3.14 as an estimate for ti.
Answer:
This question seems to be incomplete, I guess that we have a circular pool, with a diameter of 3.5 m.
Now, the circunference of a circle can be written as:
C = 2*pi*r
where:
pi = 3.14
r = radius = half of the diameter = 3.5m/2 = 1.75m
Then replacing those values in the equation for the circumference we have:
C = 2*3.14*1.75m = 10.99 m.
And knowing that the value of pi is actually larger than 3.14 (pi = 3.1415926535....)
We can safely round up the circumference to the next whole number, C = 11m
Answer:
11

Find the distance between points P(9, 5) and Q(2, 7) to the nearest tenth
Answer: 7.3
Step-by-step explanation:
To find the distance between these two points, find the difference in the x and y values then square them and add them then finally find the square root of that added number obtained.
5 - 7 = -2
9 - 2 = -7
-2^2 + -7^2 = d^2 where d is the distance
4 + 49 = d^2
53 = d^2
d = [tex]\sqrt{53}[/tex]
d= 7.2801 rounded to the nearest tenth is 7.3
is 333/106 rational?
Answer:
No
Step-by-step explanation:
333/106 is actually an irrational number, because it can not be written as a simple fraction.
Answer: Yes it is rational
Any rational number is of the form p/q where p, q are integers. The value of q cannot be 0.
In this case, p = 333 and q = 106.

Solve for n.
d=5m +9n
Answer: n= [tex]\frac{d}{9} - \frac{5m}{9}[/tex]
Step-by-step explanation:
d= 5m + 9n try to get 9n alone by subtracting 5m from both sides
d -5m = 9n Now divide both sides by 9 to get n alone
n = [tex]\frac{d}{9} - \frac{5m}{9}[/tex]

T is the midpoint of PQ. PT=3x+8 and TQ = 5x-8. What is PT?
Answer:
PT = 32
Step-by-step explanation:
From the question, we are told that:
T is the midpoint of PQ
This means:
PT = TQ
PT=3x+8 and TQ = 5x-8
Step 1
We solve for x
3x + 8 = 5x - 8
Collect like terms
8 + 8 = 5x - 3x
16 = 2x
x = 16/2
x = 8
Step 2
We can solve for PT now
PT=3x+8
x = 8
PT = 3×8 + 8
PT = 24 + 8
PT = 32
Therefore, PT = 32
I'm just curious.... How do you divide fraction? THIS IS 15 POINTS..... BTW Do not cheat use your own words! :)
Answer:
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one.
Step-by-step explanation:
Answer:
By multiplying it by the reciprocal.
½÷⅑
½*9
9/2

Multiply the fraction on the left hand side by the reciprocal of the fraction on the right hand side.

He Cost Saver Grocery Club sells sheet cakes. Each 14 sheet of cake requires 0.75 teaspoon of baking soda. Which expressions can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that appl
Answer:
y = 4(0.75) or y = 3
Step-by-step explanation:
The question is incomplete. Here is the complete question:
The cost saver grocery club sells sheet cakes. Each 1/4 sheet of cake requires 0.75 teaspoon of baking soda. Which expression can be used to find the amount of baking soda needed for a whole cake? Select all the expressions that apply.
Let the amount baking soda required for a whole cake be y.
If each 1/4 sheet of cake requires 0.75 teaspoon of baking soda, the expression that can be used to find the amount of baking soda needed for a whole is as shown below;
1/4 sheet of cake = 0.75 teaspoon of soda
1 sheet of cake = y teaspoon of soda
cross multiply
1/4 * y = 1 * 0.75
y/4 = 0.75
multiply both sides by 4
y/4 * 4 = 0.75 * 4
y = 4(0.75)
y = 3 teaspoon of baking soda
