Answer:
a) 25446.90 ft²
b) 101787.60 ft²
c) 407150.41 ft²
d) 2025πt²
Step-by-step explanation:
Data provided in the question:
Rate of spread radially = 45 feet per day
a) Radius of spread after 2 days
= 45 × 2
= 90 feet
Therefore,
Area affected = πr²
= π(90)²
= 25446.90 ft²
b) Radius of spread after 2 days
= 45 × 4
= 180 feet
Therefore,
Area affected = πr²
= π(180)²
= 101787.60 ft²
c) Radius of spread after 2 days
= 45 × 8
= 360 feet
Therefore,
Area affected = πr²
= π(360)²
= 407150.41 ft²
a) Radius of spread after t days
= 45 × t ft
Therefore,
Area affected = πr²
= π(45t)²
= 2025πt²
Answer:
A store employs 8 women and 13 men.
Then totally, they have 8 + 13 = 21 employees
=> The percentage of the employees who are women:
P = 8/21 = ~0.4 = 40%
Hope this helps!
:)
What I did was I subtracted 4500 minus 500 because it was a fee then I divide 4400 by 35 and I got 125 people.
Yes it’s true and that’s why i think so lol
Answer:
115°
Step-by-step explanation:
● DAG is equal to 180°
● DAG = DAH + HAG
● HAG IS 130°
● DAG = DAH + 130° => DAH + 130° = 180°
● DAH = 180° - 130° = 50 °
■■■■■■■■■■■■■■■■■■■■■■■■■■
ADH is a triangle
● ADH + DHA + HAD = 180°
● ADH + DHA + 50° = 180°
DHA shares the same vertex with CHE. They are opposite angles so they have the same size (35°)
● ADH + 35° + 50° = 180°
● ADH + 85° = 180°
● ADH = 180° - 85°
● ADH = 95°
■■■■■■■■■■■■■■■■■■■■■■■■■■
BDA equals 180°
● BDA = 180°
● BDH + ADH = 180°
● BDH + 95° = 180°
● BDH = 180° -95°
● BDH = 85°
■■■■■■■■■■■■■■■■■■■■■■■■■■
BDE is a traingle
● BDH+ DEB + EBD = 180°
● 85° + DEB + 30° = 180°
● DEB + 115° = 180°
● DEB = 180° - 115°
● DEB = 65°
■■■■■■■■■■■■■■■■■■■■■■■■■■
CEF equals 180°
● CEF = 180°
● DEB + x° = 180°
● 65° + x° = 180°
● x° = 180° - 65°
● x° = 115°
