Answer:
-14
Step-by-step explanation:
1. Carry out the indicated multiplication, obtaining 24a + 48 = 18a - 36.
2. Combine like terms: 6a = -84.
3. Divide both sides by 6 to isolate a: a = -84/6 = -14
The answer is C. Infinitely many because all measurements added together equals 180 degrees.
Answer: 153.56
Step-by-step explanation:
Hi, to answer this question we have to apply the next formulas:
Volume of a cone: 1/3 π r² h
Where r is the radius and h is the height (unknown)
Diameter = r x 2
8 = 2r
8/2 =r
r = 4
Before calculating the volume we have to apply the Pythagorean Theorem to find h. (where the slant is the hypotenuse and h and r are the sides of the triangle)
10 ² = h² + 4²
Solving for h
100 = h² + 16
100-16 = h²
84= h²
√84 =h
9.16= h
Back on the volume formula:
V= 1/3 π r² h
V =1/3 π 4² (9.16) =153.56
Answer:
-1/3
Step-by-step explanation:
-8x-5+3x=7+4x-9
-5x-5=7+4x-9
-5x-4x-5=7-9
-9x-5=-2
-9x=-2+5
-9x=3
x=3/-9
x=-1/3
Answer:
196
Step-by-step explanation:
70% multiply by 4/5(80%) which is 56%
56% times 350
