Domain: x≤5 (notice the closed dot on the right and the arrow on the left)
Range: y≤2 (notice the closed dot on the right and the arrow on the left)
The arrow means it keeps going infinitely. The closed dot means it stops there but is inclusive of that value.
Answer:
a =2.2
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 = c^2
where a and b are the legs and c is the hypotenuse
a^2+2^2 = 3^2
a^2 +4 = 9
a^2 = 9-4
a^2 = 5
Taking the square root of each side
sqrt(a^2) = sqrt(5)
a = sqrt(5)
a=2.236067977
To the nearest tenth
a =2.2
Answer:2.8333
Step-by-step explanation:
12 salads in 20 min
divide both by 2
6 salads in 10 min
divide by 2
3 salads in 5 min
20 min plus 20 min plus 5 min= 45 min
12+12+3=27 salads in 45 minutes
15 $50 dollar bills and 27 $20 dollar bills, a total of 42 bills
