Answer:
A $2000
Step-by-step explanation:
Let x be the least amount of money the club has to make to get $600 then...
30%x=600
We can convert 30% to a fraction. Any percentage is that number percent over hundred:
Simplify the fraction by dividing it by 10/10. Notice we can only do this since 10/10 is equivalent to 1, so in a sense we are dividing the fraction by 1:
Multiply 10 to both sides
Divide both sides by 3
The club would have to make at least $2000
Answer:
7.5
Step-by-step explanation:
7.5 is the coefficient of x
Answer:
(A, B) = (-3, -129).
Step-by-step explanation:
First convert the first equation to slop-intercept form:
x + 5y = 7
5y = -x + 7
y = -0.2x + 1.4
The slope is -0.2 so the slope of the line perpendicular to this line has slope
-1/ -0.2 = 5.
Now, converting the second equation to slope-intercept form:
15x + Ay = B
Ay = -15x + B
y = (-15/A)x + B/A
So the slope -15/A = 5 so A = -3.
So y = 5x + B/-3
Substituting the point (-8, 3)
3 = 5(-8) + B/-3
B/-3 = 43
B = - 129.
Let acute angle be x.So x+5x+90=180 so x=30
