Answer:
10
Step-by-step explanation:
4k + 5 + 6k + 10 = 115 {Exterior angle property}
4k + 6k + 5 +10 = 115
10k + 15 = 115
10k = 115 - 15
10k = 100
k = 100/10
k = 10
WE know 1 day = 24 hours
To find number of hours spent on each activity, we multiply the corresponding percentage by 24
School : 25 % --> 0.25 * 24 = 6.00 hrs
Eating : 10 % ----> 0.1 * 24 = 2.40 hrs
Sleep : 40 % ----> 0.4 * 24 = 9.60 hrs
Homework: 10 % ---->0.1 * 24 = 2.40 hrs
Free time: 15 % -----> 0.15 * 24 = 3.60 hrs
see the attached figure to better understand the problem
we know that
The equilateral triangle has three equal sides
so
in the equilateral triangle ABC
the height of the triangle is the segment BD
in the right triangle BCD
Applying the Pythagorean Theorem
solve for BD
substitute the values
therefore
<u>the answer is</u>
the height of the triangle is
Whenever it says divide just flip the fraction and change it to multiply
Yep! 2/4, also known as 1/2 is larger than 2/5. You can verify this by getting a common denominator of 20 by multiplying the top and bottom of 2/4 by 5 and the top and bottom of 2/5 by 4, and asking yourself of this is true: Does 10/20=8/20? No it does not! Therefore 2/4 is bigger than 2/5!
