Answer:
10 units
Step-by-step explanation:
Given that:
Cos a = 3 /5
From trigonometry ;
Cos θ = Adjacent / hypotenus
Side Adjacent angle a = 3 = FD
Hypotenus = 5 = DE
3 / 5 = FD / DE
FD = 6 units
3/5 = 6/DE
DE * 3/5 = 6
DE = 6 ÷ 3/5
DE = 6 * 5 /3
DE = 30 /3
DE = 10 units
Answer:
2 1/16, 10 11/16, 3 15/16
Step-by-step explanation:
3. 1 3/8 times 1 1/2= 2 1/16
4. 4 1/2 times 2 3/8= 10 11/16
5. 1 1/8 times 3 1/2= 3 15/16
Answer 9x^2
Step-by-step explanation:
3x^2+6x^2=9x^2
D, because the sum is no more than 28 so it could be equal or less than.
60% decrease.
$105-$42 = $63
$63/$105 = 0.6
0.6 x 100 = 60
