36 men can compete a piece of work in 18 days in how many days will 27 men compete the same work​
Drupady [299]

Step-by-step explanation:

Explanation:

Less Men, means more Days {Indirect Proportion}

Let the number of days be x then,

27 : 36 :: 18 : x

[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]

=>27x = 36 * 18

=> x = 24

So 24 days will be required to get work done by 27 men..

The perimeter of a triangle is 64cm ,the sides are the ratio 6:5:5 , work out the area of the triangle
Fofino [41]
The area is 192 cm^2

the sides are 20 20 24 with the base being 24

to figure out the height you have to use Pythagorean theorem of the triangle cut in half so 12^2 + b^2 = 20^2
b= 16 = height

b*h* .5= area 16* 24* .5= 192

If f(x) = 3x - 1 and g(x) = x + 2, find (1-9)(x).
Studentka2010 [4]

Answer:

(f-g)(x)=2x-3

Step-by-step explanation:

<em>The correct question is</em>

If f(x)=3x-1 and g(x)=x+2, find (f-g)(x)

we know that

(f-g)(x) is equal to subtract the function g(x) from the function f(x)

so

(f-g)(x)=f(x)-g(x)

substitute the given functions

(f-g)(x)=(3x-1)-(x+2)

Remove the parenthesis

(f-g)(x)=3x-1-x-2)

Combine like terms

(f-g)(x)=2x-3

Chang has 2 shirts: a white one and a black one. He also has 2 pairs of pants, one blue and one tan. What is the probability, if
weqwewe [10]

Answer:

The probability that Chang gets dressed with a white shirt and tan pants is 25%.

Step-by-step explanation:

Given that Chang has 2 shirts, a white one and a black one, and he also has 2 pairs of pants, one blue and one tan, to determine what is the probability, if Chang gets dressed in the dark, that he winds up wearing the white shirt and tan pants the following calculation must be performed:

Each shirt = 50% chance

Each pants = 50% chance

0.50 x 0.50 = X

0.25 = X

Therefore, the probability that Chang gets dressed with a white shirt and tan pants is 25%.
