Answer: C = 53.3 inches
A = 226.1 inches²
Step-by-step explanation:
The inscribed square has equal sides. To determine the hypotenuse of the square which is also the diameter of the circle, we would apply the Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
Hypotenuse² = 12² + 12² = 144 + 144 = 288
Hypotenuse = √288 = 16.97 inches
Radius = diameter/2 = 16.97/2 = 8.485 inches
The formula for determining the circumference of a circle is expressed as
Circumference = 2πr
Circumference = 2 × 3.14 × 8.485 = 53.3 inches
Area = πr²
Area = 3.14 × 8.485² = 226.1 inches²
The y-intercept is 60 so say you start with 60 apples. And the x-intercept is 5 so lets say you eat them all in 5 days. So the equation would look somthing like this
and would end up having a word problem that says somthing like "Jimmy has 60 apples and eats 12 a day how many days go by before Jonny has no more apples ?"
Answer:
Good Job you answered your own question
no restriction
Step-by-step explanation:
f(g(x)) means put g(x) equation into "x" in f(x) equation
so it is f(x-2+5)
f(x+3)
x+3=0
x=-3
sub back into x+5 you get 2
sub back into x-2 you get -5
What's the problem you need help with
Step-by-step explanation:
ATQ,
Let d be the number of kilograms of dark chocolate she buys and m be the number of kilograms of milk chocolate she buys.
She needs to buy 120 kg of chocolate in total for her next order, and her recipe calls for twice the amount of dark chocolate as milk chocolate.
So,
m = 2d .....(1)
m + d = 120 ...(2)
We can also solve the above equations,
Put m = 2d in equation (2)
2d + d = 120
3d=120
d = 40
Put d = 40 in equation (1)
m = 2(40)
m = 80
Hence, she will need 40 kg of dark chocolate and 80 kg of milk chocolate.
