Umm I think it is 1+1 equals 2
Answer:
In the year 2000 the number of hazardous waste sites in state y was 21
Step-by-step explanation:
Let
x ----> the number of hazardous waste sites in state x in the year 2000
y ----> the number of hazardous waste sites in state y in the year 2000
we know that
----> equation A
----> equation B
Solve the system of equations by substitution
Substitute equation B in equation A
Solve for y
Adds 8 both sides
Divide by 2 both sides
therefore
In the year 2000 the number of hazardous waste sites in state y was 21

Answer:
1.28 or 912/715
Step-by-step explanation:
sine= opposite side/hypotenuse
cos=adjacent/ hypotenuse
sine a= 12/13 using the Pythagorean Theorem and solve for the missing side. (which is the adjacent side)
cos a = 5/13
Do the same for sine b
cos b= 9.8/11
add both the cosine value
(5/13)+(9.8/11)=1.28 or 912/715 in fraction form
A or 16/784
because there are 28 chips total 4 of them are green so it is 4/28
but you pick twice so you square it (4/28)^2=16/784
