Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).
So, 5/12 and 10/24.</span>
Answer:
0.03
3/100
Step-by-step explanation:
because 3 percent of a hundred can be written as a fraction and 3 percent is three one hundreths which can be written as a decimal.
17. 3(4-2(-2))......3(2(-2)).....3(-4).....-12
18. 2(-3)-3(3)......-6--9......-6+9.....3
19. 1,234.6
Answer:
cos(18°)=sin(72°)
Step-by-step explanation:
we know that
In a right triangle
cos(A)=sin(B)
If A and B are complementary angles
so
A+B=90°
In this problem
A=18°
B=90-18=72°
therefore
cos(18°)=sin(72°)
Answer:
her supply has 18 pounds
Explanation:
Assume that the number of pounds in her supply is x.
We are given that:
She uses 1/3 x in salted mix and 2/9 x in unsalted mix.
This means that:
Total amount used = 1/3 x + 2/9 x = 5/9 x of her supply
Now, we are also given that:
She used 10 pounds of her supply.
This means that:
5/9 x = 10
5x = 9*10 = 90
x = 18 pounds
Hope this helps :)
