5 people build 3 huts in 21 days . Find the number of people that will build 6 huts in 15 days ?
Answers
3 huts are built by 5 people in 21 days.
So 1 hut is built by 5 people in 7 days.
That is to say, 1 hut requires 5*7 = 35 man-days.
Which means 6 huts need 6*35 = 210 man-days.
If the time available is 15 days, 6 huts will need 210 man-days/15 days = 14 people.
Answer = 14 people.

Answer:
n = 6 probably
Step-by-step explanation:
10 + I 10n + 6 I+ = 76
since " I I " means it will always be positive we can kinda just ignore it
10 + 10n + 6 = 76
16 + 10n = 76
10n = 76 - 16
10n = 60
n = 6
In class VIII, there are 140 students. The ratio of boys to girls is 4:3. a) Find number of girls. b) Find number of boys.
Answers
Answer:
A) 60 girls B)80 boys
Step-by-step explanation:
Pretend that the ratio is a fraction. If there are 4 boys for every 4 girls, than pretend that you add the 4 and the 3 together, thus giving you 7 as your denominator. Start with the girls, giving you a fraction of 3/7, multiply by 140, you get 60 as the number of girls. 140-60=80, giving you 80 boys.

A-b =56
A:b is equal to 9:2
Answers
Answer:
A = 72
B = 16
Step-by-step explanation:
Ratio problems can often be worked by considering them in terms of "ratio units." Here, the difference in ratio units is 9-2 = 7. The difference between the actual numbers is A -B = 56. This means each ratio unit stands for an actual number value of 56/7 = 8
Then the ratio of actual values is ...
A : B = (9·8) : (2·8) = 72 : 16
Check: These actual values of A and B have a difference of 72-16 = 56.
(A, B) = (72, 16)

We first want to draw a diagram with the given information.
I am unsure if the image shows below, or if it is an attachment.
We then see we have a right triangle. What is a theorem that is commonly associated with right triangles?
So we use the pythagorean theorem to find the missing leg of the triangle has a length of 4 cm. But how does this help us? Well, when finding the distance from the center of a circle to a chord, we always find the line that is perpendicular to the chord and divides it in half (and passes through the center), and find the length.
So, the leg of length 4 we just found? That's half of our answer.
Since 4 × 2 = 8, we know that the length of AB is 8 cm.

Step-by-step explanation:
Since this is a rectangle, we know that each corner's angle is 90 degrees. (The box thing at the bottom right shows this.)
Since the two angles that make up angle E sum up to 90, we can make an equation:
(9x - 6) + (2x + 8) = 90
11x + 2 = 90
11x = 88

It rained 3/8 cm more on Tuesday than Monday.

What I first did is convert the fraction 3/4 into 6/8 (multiply both sides by two) so I could get a common numerator to solve the two fractions. Then, I gave one whole from the 2 wholes in 2 1/8 to 1/8 to make it easy to subtract with 6/8 (I wuldn't like to do 1/8-6-/8) and made it into 9/8. Then it's simple subtraction (oh yes and don't forget to turn the 2 into 1 since it lost a whole) and voila! 3/8 cm
