Answer:
5
Step-by-step explanation:
|a−b| − |c+d| , if a=−5; b=4; c=1; d=−3
= a + b - c + d
= 5 + 4 - 1 + (-3)
= 5 + 4 - 1 - 3
= 5 + 4 - 4
= <em><u>5</u></em>
Answer:
5 2/5
Step-by-step explanation:
(2 1/4) / x = (1 1/2) / (3 3/5)
so
x = (2 1/4) * (3 3/5) / (1 1/2)
Answer:
10.26 in²
Step-by-step explanation:
The area (A) of the sector is
A = area of circle × fraction of circle
= πr² × 
= π × 2.8² ×
≈ 10.26 in²
Answer:
25%
Step-by-step explanation:
The (not mentioned in the question) set is: 6 7 8 9.
There are 4 total outcomes and only 1 favorable outcome, then the probability to pick a 9 is:
P(9) = favorable outcome/total outcomes
P(9) = 1/4 = 0.25 or 0.25*100 = 25%
