Answer:
$36.9135
Step-by-step explanation:
Markup = 17% of 31.55
= 17/100 × 31.55
= 5.3635
Retail price = whole sale price + markup
= 31.55 + 5.3635
= $36.9135
Answer:
1/7 +5/9={1×9+5×7)/(9×7)=44/63is your answer
What kind of question is this ?
or in other words
3 is the opposite, and 5 is the hypotenuse.
You can use the pythagorean theorem to find the other side(adjacent)
a²+b²=c²
3²+b²=5²
9+b²=25 Subtract 9 on both sides
b²=16 Square root both sides
b = √16
b = 4
So the adjacent is 4.
tan theta = opposite/adjacent
tan theta = 3/4
Answer:
89
Step-by-step explanation:
Given that the class has 28 students has 7 juniors and 21 seniors
mean score of the juniors = 73
Therefore, total score of junior = 73 × 7
= 511
mean score of seniors = y
Total score of seniors = 21y
Total score of the class = 511 + 21y
Mean score of the class = 85
Total score of the class = 85 × 28
= 2380
therefore,
511 + 21y = 2380
21y = 2380 -511
21y = 1869
y = 1869/21
y = 89
