Mr. Rowley: 16:14 which reduces to 8:7
Ms. Rivera: 64:60 -> 16:15
The ratios are not equivalent because when they are reduced, they do not equal the same thing.
Is the 8 with the problem?
Answer: x = 11
Step-by-step explanation:
same as the last question, set them as equal and solve. here's my work:
<em>5x - 1 = 4x + 10</em>
<em>5x - 1 (+ 1) = 4x + 10 (+ 1)</em>
<em>5x = 4x + 11</em>
<em>5x (- 4x) = 4x (- 4x) + 11</em>
x = 11
Answer:
Step-by-step explanation:
Thales theorem tells us that B is a 90
and therefore from W to o (center) is 45°
we know the total of the arc VoW is 98
180= 8x +1 + 45 +98
36 = 8x
4.5 = x
x = 4.5
Answer:
SA= 902.88 yd²
V = 1386.24 yd³
Step-by-step explanation:
Surface area
Since the bases are right triangles, you need to find the base of the triangle. Use Pythagorean theorem as you are given the hypotenuse and one leg.
19² = 15.2² + b²
361 = 231.04 + b²
Subtract 231.04 from both sides
b² = 129.96
Root that
b = 11.4
Now that you have the base, find the areas of the triangles and rectangles.
<em>Triangles</em> - (15.2*11.4)1/2 (2)
15.2*11.4 = 173.28
<em>Rectangles </em>- (15.2)(16) = 243.2
(16)(11.4) = 182.4
(16)(19) = 304
Add them all together and the SA equals 902.88 yd²
Volume
V = Bh
V = 1/2(15.2)(11.4)(16)
V = 1/2 (2772.48)
V = 1386.24 yd³
