Answer:
a spinner divided into 4 congruent sectors, spun 7 times
Step-by-step explanation:
s = the number of student tickets sold
a = the number of adult tickets sold
The drama class sold 25 more student tickets than adult tickets to the fall play
s = a + 25
The class collected $660 from ticket sales:
6s + 3a = 660 divide both sides by 3
2s + a = 220
by solving the system of equations
s = a + 25
2s + a = 220
we find
s = 81.67 student tickets
a = 56.67 adult tickets
Answer:
Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of 0 , then you have a terminating decimal.
Step-by-step explanation:
Convert the fraction 7/12
to a decimal.
7/12=0.583¯
This is a repeating decimal.
The bar over the number, in this case 3, indicates the number or block of numbers that repeat unendingly.
Answer:
K = (1/2)r^2(sin(θ) +θ)
Step-by-step explanation:
The area of the triangle to the left is ...
A1 = (1/2)r^2·sin(180°-θ) = (1/2)r^2·sin(θ)
The area of the sector to the right is ...
A2 = (1/2)r^2θ
so the total area of the blue shaded region is ...
K = A1 + A2 = (1/2)r^2·sin(θ) + (1/2)r^2·θ
K = (1/2)r^2(sin(θ) +θ)
One of the reasons could be , because he was covering up the negative results and showing only the positive side of it .
