Answer:
24.0 square feet
Step-by-step explanation:
The area of the sector is given by ...
A = (1/2)r²θ . . . . . where θ is the angle in radians
The area of the circle is the same, with θ=2π, so is ...
A = πr²
__
In this problem, the area of the sector is ...
A = (1/2)(9 ft)²(24π/180) = 27π/5 ft² ≈ 16.9646 ft²
The area of the circle is ...
A = π(1.5 ft)² = 9π/4 ft² ≈ 7.0686 ft²
Then the total area of the exclamation point is ...
16.9646 +7.0686 ≈ 24.0 . . . ft²
The area is about 24.0 square feet.
5/7=x/10
Cross multiply
(5)(10)=50
(7)(x)=7x
7x=50
Divide by 7 for both sides
7x/7=50/7
x=50/7 or x=7 1/7
Answer: x=50/7 or x=7 1/7
Answer:
x= 17 and y=20
Step-by-step explanation:
4x- 3y= 8-------1
5x-4y= 5-------2
Subtracting 2 from 1
5x-4y= 5
-4x+3y=-8
x-y=-3----------3
From 3 we have x= y-3-------4
Putting 4 in 1
4(y-3) -3y= 8
4y - 12 -3y= 8
y= 8+12
y=20------------5
Putting 5 in 2
5x - 4(20)= 5
5x=5+80
5x= 85
x= 17------6

Here's the solution ~



Now we will use this identity in denominator
[ a² - b² = (a + b)(a - b) ]
