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: (3x−2)(4x−1)
Step-by-step explanation:
<em>Start factoring with -11x.</em>
12x^(2)-11x+2
12x2+(−8−3)x+2
12x2+(−8x−3x)+2
12x2−8x−3x+2
<em>Factor the highest common denominator of each group.</em>
<em>Group the first two terms and the last two.</em>
(12x2−8x)+(−3x+2)
<em>Factor the highest common denominator (MCD) of each group.</em>
<em>4x(3x−2)−(3x−2)</em>
<em>Factoring the highest common denominator 3x−2.</em>
(3x−2)(4x−1)
Country music cd- $12
Rock music cd- 12× 2/3 = $8
Platinum edition cd- $8 x 2 = $16
16+12+8 = $36
Hope this helps :3
Standard form: Ax + by =C
so
y+ 1 = 3/4(x - 16)
4(y + 1) = 3(x - 16)
4y + 4 = 3x - 48
3x - 4y = 52
Answer is D. last option
3x - 4y = 52
