Answer:
tan A = -15/8.
Step-by-step explanation:
sin^2a = 1 - cos^2A
= 1 - (-8/17)^2
= 225/289
So sin A= 15/17
tan A = sin A / cos A
= 15/17 / -8/17
= 15/-8
= -15/8.

Let the price of flowers in September be x, then (100 + 20)/100 * x = $1.50
120/100 * x = $1.50
1.2x = $1.50
x = $1.50/1.2 = $1.25
The price of flowers in September is $1.25
Total money realised in September = $1.25 x 900 = $1,125
40% earned = 0.4 x $1,125 = $450
Total money realised in October = $1.50 x 700 = $1,050
40% earned = 0.4 x $1,050 = $420
The class earned more money in September and they earned $30 more than in October.
Find the greatest common factor (GCF) of 9 and 12 using factor trees. The GCF is 3
Divide each term (9 and 12) over 3
9/3 = 3
12/3 = 4
So 9/12 reduces to 3/4
In other words, 9/12 = 3/4
--------------------------------------
Now focusing on 3/4, we can multiply top and bottom by the same value. Let's say we multiply top and bottom by 5
3*5 = 15
4*5 = 20
So 3/4 = 15/20
--------------------------------------
So two ratios equivalent to 9/12 are 3/4 and 15/20. There are infinitely other ratios that are equivalent.
In short, the answers are 3/4 and 15/20.
≤5
Multiplying by 20 in all sides gives:
g≤(20×5)
Answer: g≤100
