Answer:
12) 5.96 ; 13)
Step-by-step explanation:
12). x and 5 are legs, so
opposite leg/adjacent leg = tangent 40°
5/x= tan40°, 5= x*tan40°, x= 5/tan40° ≈ 5.96
13). 15 is opposite leg
24 is hypotenuse
opposite leg/hypotenuse = sin(x)
sin(x) = 15/24
x = arcsin(15/24) ≈ 38.68°
After reading the problem, you are often asked to solve it.
Answer:
1) There were 120 customers per night when the restaurant opened
2) y = -2x + 24
Step-by-step explanation:
1) x represents the # of months since a restaurant opened, and y represents the average number of nightly customers.
y=mx+b
120 is <em>b</em> in this situation, which is the y-intercept of the line. This means that 120 is the starting number of customers when the restaurant first opened.
The answer is 0.36. I don't think u need to explain why, right ;)
‘a’ is a variable
so this means something multiplied by 1/2 = 11
to solve we will divide both sides by 1/2 to isolate ‘a’
so a= 22
you can verify by plugging 22 into a
so
(1/2)(22)=11
which is true
