Step-by-step explanation:
Sum of angles in a quadrilateral = 360°
Sum of first 3 angles = 360° - 100° = 260°.
260° / (4 + 6 + 3) = 20°.
First angle = (20°) * 4 = 80°
Second angle = (20°) * 6 = 120°
Third angle = (20°) * 3 = 60°
The angles are 80°, 120° and 60°.

Answer:
p(chocolate chip) = 2/7
p(oatmeal) = 7/27
Step-by-step explanation:
probability = favorable outcomes/total outcomes
First, add up all the cookies in the bag.
8 + 6 + 7 + 7 = 28
Next find the probability of selecting a chocolate chip cookie. Since there are 8 chocolate chip cookies and 28 cookies in the bag, create a fraction.
p(chocolate chip) = 8/28
reduce by 4
p(chocolate chip) = 2/7
Now that the cookie was eaten that will reduce the number of chocolate chip cookies to 7 and the overall number of cookies to 27.
There are 7 oatmeal cookies and 27 total cookies, so create the fraction.
p(oatmeal) = 7/27
Answer:
a: 1.26
b: 8190
Step-by-step explanation:
The account had a 26% increase. Therefore, you would multiply the original amount by 1.26.
1.26 x 6500 = 8190
