5 hours
Step-by-step explanation:
so you do 8 times 4
which gives you 32
72 - 32
40 divided by 8
5

Answer:
56 ft
Step-by-step explanation:
The geometry can be modeled by a right triangle with an unknown hypotenuse, and a side opposite the 30° angle that is 28 ft.
sin(30°) = (28 ft)/hypotenuse
hypotenuse = (28 ft)/sin(30°) = 56 ft
The length of the escalator is 56 feet.
Answer:
10 degrees
Step-by-step explanation:
Bisection means dividing into two equal parts
So, if we bisect an angle measuring 20 degrees
It will divide into 2 equal parts and:
=> 20/2 = 10 degrees
Two angles of 10 degrees will be formed.
Her profit was 126$ because she spent 24$ on her materials and then charged 5$ per 2 so you get 150$ then subtract the 24

Answer:
an = 6n -2
Or
an+1 = an +6
Step-by-step explanation:
to go from 4 to 10 we add 6 tiles
to go from 10 to 16 we add 6 tiles
We add 6 tiles each time
an = a1 + d(n-1) where an is the value of the nth term a1 is the first term d is the common factor and n is the term number
an = 4 + 6( n-1)
an = 4 + 6n -6
an = 6n -2
Or
an+1 = an +6
