B) 4.90
Hope that helped :)
Assuming that Anita needs hollow right circular cones, we are solving for its lateral surface area, which is given by the formula πr√(h²+r²), where r is the radius and h is the height.
r = 6 ft / 2 = 3 ft
Solving for the lateral surface area of one cone:
LSA = (3.14) (3) [√(12²+3²)] = 116.52 sq ft.
Since she needs 10 cones:
10 * 116.52 sq. ft = 1,165.2 sq ft.
She will need 1,165.2 sq ft of material.
Answer:
(x,y)=(5-2y,y), y belongs to all real numbers
Step-by-step explanation:
x=5-2y
3x=15-6y
3(5-2y)=15-6y
15-6y=15-6y
y∈All Real Numbers
(x,y)=(5-2y,y), y∈All Real Numbers
Answer:
1/y -84
Step-by-step explanation:
7y/12-84
simplify= 1/y-84
Answer:
x= 7
Step-by-step explanation:
The equation is 8+4= 2(x-1)
Distribute into the parenthesis.
8+4= 2x-2
Now, add.
12= 2x-2
Add 2 to both sides.
12= 2x-2
+2 +2
Then, divide by 2 to both sides to isolate the variable.
<u>14</u>= <u>2x</u>
2 2
x=7
