The height of the triangle if the base is 8 is 3.96 units

Given the following parameters

Base of a triangle = 8 units

Let the hypotenuse be "c"

Let the height be "h"

If the length of the hypotenuse of a right triangle is one unit more than twice the height, then;

c = 2h + 1

According to the Pythagoras theorem:

c² = b² + h²

(2h + 1)² = 8² + h²

Expand

4h²+4h+1 = 64 + h²

4h²-h² + 4h + 1 - 64 = 0

3h² + 4h - 63 = 0

Factorize the result

On factorizing, the value of the height is 2

h = \frac{-2}{3}+\frac{\sqrt{193} }3\\

h = 11.89/3

h = 3.96 units

Hence the height of the triangle if the base is 8 is 3.96 units

You divide a number and get a remainder of 4. what 1 - digit number can the divisor of the problem?
ahrayia [7]

Answer:

<em>Any of the numbers 5,6,7,8,9 could be the divisor of the problem.</em>

Step-by-step explanation:

<u>Division</u>

If I divide a number and get a remainder of 4, then the divisor must be greater than 4. A divisor of 4, for example, would lead to a remainder of (maximum) 3.

Thus, our divisor can only be one among the numbers: 5,6,7,8,9. If the dividend is exactly 4, then the divisions

4/5, 4/6, 4/7, 4/8, and 4/9

they all produce the same remainder of 4.

Thus, any of the numbers 5,6,7,8,9 could be the divisor of the problem

yKpoI14uk [10]

Answer:

  • 168 in 7 hours.

Step-by-step explanation:

<u>We can't multiply.</u>

<u>We got to count up by 12's for each 1/2 hour.</u>

12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168.

<u>Simplified:</u>

  • 24, 48, 72, 96, 120, 144, 168.

<u>Estimate:</u>

  • 12 = 1/2 hour
  • 24 = 1 hour
  • 36 = 1 1/2 hours
  • 48 = 2 hours
  • 60 = 2 1/2 hours
  • 72 = 3 hours
  • 84 = 3 1/2 hours
  • 96 = 4 hours
  • 108 = 4 1/2 hours
  • 120 = 5 hours.
  • 132 = 5 1/2 hours
  • 144 = 6 hours
  • 156 = 6 1/2 hours
  • 168 = 7 hours.

Answer is 168.

Need urgent help in mathematics!! Will mark brainliest!!!!
sesenic [268]

Hey there!!

How do we solve this problem :

We will use the combinations formula to solve this :

c ( n , r ) where n = 11 and r = 2

c ( n , r ) =  n ! / r ! ( n - r ) !

... 11 ! / 2 ! ( 11 - 2 ) !

... 11! / 2! × 9!

... 11! / 2 × 9!

... 11×10×9×8×7×6×5×4×3×2 / 2×9×8×7×6×5×4×3×2

... 11×10 / 2

... 11 × 5

... 55 combinations.

Hence, the required answer = 55 , option ( d )

Hope my answer helps!
