Step-by-step explanation:

Reduction= 75%

Current commute time=m-(75% of m)

Where 75% equals 3/4 and of= "×"

Alex Ar [27]

Answer: There are 140 adults and 40 children.

Step-by-step explanation:

Let 2x = Number of children

7x = Number of adults.

As there are 100 more adults than children.

That means, $7x-2x = 100$

$\Rightarrow\ 5x=100\\\\\Rightarrow\ x=\dfrac{100}{5}\\\\\Rightarrow\ x=20$

Number of children = 2 (20)=40

Number of adults = 7(20) = 140

Hence, there are 140 adults and 40 children.

Can someone solve Pythagorean theorem

Ad libitum [116K]

Answer:

48 units

b= 48 units

Step-by-step explanation:

pythag is $a^2+b^2=c^2$

we have a and c

so substitute them in

$14^2+b^2=50^2$

now you can solve

$196+b^2=2500$

subtract 196 from both sides

$b^2=2500-196$

subtract

2500 - 196 = 2304

$b^2=2304$

solve for the square root

square root of 2304= 48

therefore b= 48 units
