Answer:
Step-by-step explanation:
Given the information of the conical hat
- diameter of 16 inches => Radius = 8 inches
- height of 9 inches
=> the slant height of the hat is (use Pythagorean Theorem)
=
<=>
=
<=> s =
The area (without the base area) of tissue paper will she need to make one hat is:
SA = πrs in2
<=> SA = π*8*
in2
<=> SA =8
π
=> the total tissue paper will she need for 21 hats is:
SA*21
= 8
π*21
= 6352,18 in 2
Answer: x= -10 and Y=-20
Step-by-step explanation:
If y is equal to 2x that mean you need to substitute Y=5x+30 like this 2x=5x+30
Answer:
250
Step-by-step explanation:
Let x = the number of adult tickets sold
Let x + 53= the number of student tickets sold
x + x + 53 = 553
2x = 500
x = 250
2x + 53 = 553
