Answer:
27
Step-by-step explanation:
Given that the total number of people protesting is 81. These people are either male - Student or non student or Females (student or non students)
Given that there are 36 males then number of females
= 81 - 36
= 45
If there are 18 females non students then the number of females protesting that are students
= 45 - 18
= 27
Answer:
a = -3 and b=5
Step-by-step explanation:
Given that 10 can be written as 2*5 or √2*√2*5, and √18 can be written as √(2*9) or √2*√9 or 3√2, you can write the fraction as:
![\frac{5\cdot\sqrt2\cdot\sqrt2-3\sqrt2}{\sqrt2}](https://tex.z-dn.net/?f=%5Cfrac%7B5%5Ccdot%5Csqrt2%5Ccdot%5Csqrt2-3%5Csqrt2%7D%7B%5Csqrt2%7D)
So getting rid of the √2 factor, you get 5√2 - 3, so a=-3 and b=5
Answer:
1-Two angles are called complementary when their measures add to 90 degrees
EXAMPLES= 30 AND 60 DEGREES ANGLE
40 AND 50 DEGREES ANGLE
80 AND 10 DEGREES ANGLE
2-An acute angle is an angle that measures less than 90 degrees.
EXAMPLES = 40 DEGREE ANGLE
10 DEGREE ANGLE
45 DEGREE ANGLE
Answer:
27
Step-by-step explanation:
First solve 3a - 9= 6
3a - 9 = 6 add 9
3a = 15 divide by 3
a = 5
Now that you know a is 5, put that in the other expression.
5a + 2
= 5(5) + 2
= 25 + 2
= 27
First, let's multiply the numbers in the fractions:
100/10
Because both these numbers are divisible by 10, we divide both sides by 10:
10/1
This can just be simplified to:
10
