I'm assuming the deck is the shaded area.
To find the area of the deck, find the area of the large circle and subtract the area of the small circle from it:
A of large circle: R = (4.2/2) + 1.7 = 3.8; area: 3.8^2 * pi is about 45.3.
A of small circle: r = 4.2/2 = 2.1; area: 2.1^2 * pi is about 13.8
Now, subtract:
45.3 - 13.8 = 31.5 meters squared
Answer:
f^-1(x)=³√[(x+7)÷4]
Step-by-step explanation:
f(x)=4x^3-7
y=4x^3-7
interchange 'y' with 'x'
x=4y^3-7
make y the subject
4y^3=x+7
divide by 4 both sides
y^3=(x+7)÷4
multiply by the cube root both sides
³√(y^3)=³√[(x+7)÷4]
y=³√[(x+7)÷4]
f^-1(x)=³√[(x+7)÷4]
Answer:
B. 4/21
Step-by-step explanation:
⇒This question is on probability
⇒Number of boys=3
⇒Number of girls=4
⇒P(S)= 4+3=7
Probability for a girl to win is= 4/7
We have 3 awards a free movie ticket, a collectible poster, or a free popcorn
P(S)= 3
Probability of being awarded a free popcorn = 1/3
The probability that a girl will win free popcorn =
4/7 * 1/3 = 4/21
hope i helped and have a wonderful day

It depends, are you trying to find area or perimeter?
Answer:
x= -3/16
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
