Answer:
? = 95 degrees
Use your complementary angles to solve for the missing angle. Remember a line is 180 degrees and any triangle whether its obtuse or acute it also equal 180.
Answer:
36 boys
Step-by-step explanation:
let x be the number of pupils in the class , then
x + 24 = x ( multiply through by 5 to clear the fraction )
3x + 120 = 5x ( subtract 3x from both sides )
120 = 2x ( divide both sides by 2 )
60 = x
Then
number of boys = × 60 = 3 × 12 = 36
Answer:
subtract 4 from 12
Step-by-step explanation:
Answer:
- 2/9, 2/7, 1/10, 1/6, 1/4, 1/7, 1/16, 5/3
Step-by-step explanation:
A: 2/3 divided by 3
B: 6/7 divided by 3
C: 2/5 divided by 4
D: 5/6 divided by 5
E: 10/8 divided by 5
- 10/8 : 5 = 5/4 * 1/5 = 1/4
F: 4/7 divided by 4
G: 5/8 divided by 10
-
5/8 : 10 = 5/8*1/10 = 1/16
H: 20/6 divided by 2
- 20/6 : 2 = 10/3 * 1/2 = 5/3
This is like the equation of a line where y is the area, x is the time, and 8.5% is your slope. So you have y=0.085x+b (reason why I switched 8.5% into 0.085 is because that is how you write a percent as a decimal).So now you need to find what b is. So you know orignally the area is 2400km^2 at x=0 years (this is what it is initially).If you plug those numbers in you have:2400=0.085(0)+bThen after solving for b, you can write your equation as:y=0.085x+(whatever you found b to be)Then plug 13 in for x and you have your answer. y=-.085(13)+2400
