Answer:
the other percentage is 70 percent if thats what your asking.
Step-by-step explanation:
Answer:
slope = 
Step-by-step explanation:
Slope-intercept form is the way in which an equation is written to easily identify the line's slope and y-intercept. It is represented by the equation y = mx + b, in which m represents the slope.
By looking at the equation, we can see that it takes the y = mx + b format - y is isolated - therefore it is in slope-intercept form. Remember that the number in place of the m would represent the slope - and in this case, that number is .
The answer:
cot(theta)=1.5, to find theta, cot(theta)=1.5 implies theta= arc cot (1.5)
but we kknow that cot(theta) = 1 / tan(theta), this implies
1 / tan(theta) =1.5, and tan(theta) = 1 / 1.5 = 0.6
and theta is in quadrant 3, costheta and sintheta are negatives
so tan(theta) is positive,
tan(theta) = 0.6, therefore, (theta) = arctan ( 0.6)= 30.9°
finally (theta) = 30.9°
Answer:
B and D
Step-by-step explanation:
Equations with the same x- term on both sides will have no solution
A
4x - 13 = 5(x + 4) = 5x + 20
4x ≠ 5x
This equation has a solution
B
5(3 + 2x) = 10x + 4
15 + 10x = 10x + 4
10x on both sides ⇒ no solution
C
2(3 - 5x) = 8(x + 1)
6 - 10x = 8x + 8
- 10x ≠ 8x
This equation has a solution
D
9x - 6 = 3(3x - 2) = 9x - 6
9x on both sides ⇒ no solution
Answer:
The answer is 30
Step-by-step explanation:
If you were to do 50% of 30, it would be 15 students that are girls. There's 18 students that are girls though, so the extra 10% would make 18 students in the class girls. The remaining 40% would be 12 boys. So basically you're taking 10% from one side and putting it in the other because 50% of 30 is 15 (well this is at least how I would do it, I don't know how others would do it though)
