Hullan's age is three times Thomas's age. The sum of their ages is 92. What is Thomas's age?
Ksju [112]

Answer: 23

Step-by-step explanation: You can start by setting this up as an equation like so,

X + 3(X) =92 where x is Thomas’ age and the 3x indicates Hullans age being 3 times greater than Thomas.

Combine the x’s

4(x) = 92

Divide by 4 X = 92/4

92/4 = 23, x = 23

A triangle has one leg that measures 14 feet and the hypotenuse is 50 feet. What is the length of the other leg?
Aliun [14]
Ok so we are using the Pythagorean theorem so were gonna do A^2 + B^2 = C^2

It don't say which leg we have so you can use either a or b.
Which would get us 14^2 + B^2 = 50^2
14*14 =196 , 50 *50 =2500
Then we have to  subtract the two.
So 2500 - 196 = 2,304
Then you take the take the square root of that answer and you have your other leg. 
The square root of 2,304 is 48
So the missing leg = 48

. The volume of a box is 405 cubic units. The length is x units, the width 4 units greater than the length, and the height is 9
lukranit [14]

Answer:

length = 5

width = 9

Step-by-step explanation:

V = lwh

let 'x' = length

let '4+x' = width

9 = height

405 = 9x(4+x)

405 = 36x + 9x²

this is a quadratic equation:  9x² + 36x - 405 = 0

factor out a 9 to get:

9(x² + 4x - 45) = 0

9(x-5)(x+9) = 0

one root is 5 and the other is -9

since distance cannot be negative we use 5 as the length and 9 is the width
