Answer:
Just took the quiz. Answer is D. 25/2 (sqrt(2)+sqrt(6))+65
Step-by-step explanation:
Since the three angles of a triangle add to give 180°
The the size of the largest angle 4 = 180° ×
= 180° ×
∴ the size of the largest angle = 80°
2n + 28 = 96 [Two times n plus twenty-eight equals ninety-six.}
You need to get n by itself, so you first subtract 28 on both sides
2n + 28 - 28 = 96 - 28
2n = 68 Divide 2 on both sides
n = 34
Answer:
B. 5 and 1/4 percent
Step-by-step explanation:
Step one:
given
principal= $2460
time= 3 and 1/2 years= 3.5 years
SI= $452
Required
The rate
Step two:
we know that
SI= PRT/100
substituting our data we have
452= 2460*R*3.5/100
452=8610R/100
cross multiply
452*100= 8610R
divide both sides by 8610
45200/8610= R
R= 5.25%
R= 5 and 1/4 percent
