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

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

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:

YES

Step-by-step explanation:

Rectangle: (n)+(n)+(n+2)+(n+2)=4n+4

Square: (n+1)+(n+1)+(n+1)+(n+1)=4n+4

4n+4=4n+4

Yes, they are equal in perimeter.

Answer:

they have equal perimeter.

Step-by-step explanation:

perimeter :-

.Rectangle=2(n+2+n)=2(2n+2)=4(n+1)

Square=4(n+1)

Answer:

0.58

Step-by-step explanation:

58/100 = 0.58

Since hundred has two zeros, it moves forward twice and hence the decimal point ends in front of the 5 making is 0.58

Step-by-step explanation:

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

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:

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]  

Answer:

68.8 yards

Step-by-step explanation:

We can do justice to this question using proportion,

Proportion in mathematics means that two ratios are equal it can be expressed as w/x = y/z

Let us denote the field on map as Z

Then we can say

5 inches on the map/ 2 yards in the park = 175inches/ X yards

If we cross multiply

5(Z )= 172 × 2

5(Z ) = 344

Make Z subject of the formula

Z= 344/5

Z= 68.8 yards

Hence the the actual park is 68.8 yards

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.

Answer:

9/20 pages/minute = .45 pages/min

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.

Answer:

the right answer is 56.25

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
