8.700 + 0.006
8.706 (false)
8 + 0.70 + 0.06
8.70 + 0.06
8.76 (true)
Answer:
a. AA
b. no (sides are not proportional)
Step-by-step explanation:
a. Two angles are marked as congruent. The triangles are similar by the AA postulate.
__
b. The side ratios 6 : 8 : 11 and 15 : 20 : 33 are both in reduced form. They are clearly not identical, so sides are not proportional. The triangles are not similar.
Answer: 151.25 cm^2
explanation: separate into rectangle and semi circle. you can find out the diameter and radius of the semi circle by subtracting the 6 from the top from the 16 of the bottom because the diameter of the circle plus the 6 take up the same length.
16 - 6 = 10
for radius divide by 2
10 / 2 = 5
area of rectangle: l x w
16 x 7 = 112
area of semi circle: 1/2(pi)r^2
1/2(3.14)5^25 = 39.25
add up the two areas to find the area of the entire figure
112 + 39.25 = 151.25
Answer:
3/4, 75% chance
Step-by-step explanation:
you have four in total, three of which are not c, so you have a three out of four chance of NOT picking c. 3/4 as a percentage is 75%
