So first we want to say, 8 out of the 40 flowers were perennials.
8 out of 40 is 8/40, or simplified down to 1/5.
1/5 in percentage form is 20% because 1 divided by 5 = 20%.
A)
145 - 5d
5d = 145, set equal
29 days to lay all the track
b)
5*19 = 95
145-95 = 50
After 19 days, they have 50 miles to go.
ABD: 22
DBC: 109
they are congruent angles
It would be .2 not 2 because the smaller number is first
2 divided by 10 is .2
Answer:
Area of circle: 1662.57 cm
Circumference of circle: 144.57 cm
Step-by-step explanation:
Formula of area of circle:
pi x r2 or radius x radius
So, it's 22/7 x 23 x 23 = 1662.571429
Formula of circumference of circle:
2 x pi x radius OR
pi x diameter
Let's use the second method, to find diameter it is radius x 2 = 46
So,
46 x 22/7 = 144.5714286
