Answer:
- ornament area = 379.8 cm²
- paint needed: 114 bottles
Step-by-step explanation:
The surface area of one cone with slant height s and radius r is ...
SA = πr² +πrs = πr(r+s)
For the cone that is half an ornament, the surface area is ...
SA = (3.14)(4.2 cm)(4.2 cm + 10.2 cm) = 189.9072 cm²
The area of one ornament is the area of two cones:
one ornament area = 2×189.9072 cm² ≈ 379.8 cm²
60 ornaments will be 120 cones, so will have a total surface area of ...
total area = 120(189.9072 cm²) = 22,788.864 cm²
__
If one bottle of paint will cover 201 cm², then the number of bottles of paint required is ...
(22788.864 cm²)/(201 cm²/bottle) ≈ 113.4 bottles
<span>We are given the equation 8y^2 - 33y + 25.
First multiply the first and the last coefficients: 8x25 = 200
Now we need to factorize 200 such that these factors add up to the middle coefficient -33. By trial and error, we find that
200 = (-8) x (-25)
and
-25 - 8 = -33
So,
</span>8y^2 - 33y + 25
= 8y^2 - 25y - 8y + 25
= y(8y - 25) - (8y - 25)
= (y-1)(8y - 25)
An acute angle is an angle less than 90 degrees. So the answer would have to be less than 90 to support her claim. This eliminates 1 and 2. Because measure A and measure B are congruent they have to be the same angle which would eliminate number 3. So, the answer is 4
