Answer:
greater than
Step-by-step explanation:
63,459 is 542 more than 62,935
You should be able to answer this by glancing at it. But if you can't,
then you have to set up an equation.
Call the unknown number ' Z '.
You said that 0.4 = 10 Z
Divide each side of the equation by 10 : Z = 0.4 / 10 = <em>0.04</em>
Answer:
35
Step-by-step explanation:
Here we see 5 black keys for every 7 white keys.
So the ratio is 5:7
If we need 49 white keys, find the amount we scale the original ratio by:
49/7 = 7
So we are scaling by a factor of 7.
The number of black keys would be 5 * the scale of 7. = 35
So there should be 35 black keys.
1/9 = 0.1111111111...
That's a repeating decimal because the 1 repeats over and over again.
1/3 = 0.33333333...
That's a repeating decimal because the 3 repeats over and over again.
Have an awesome day! :)
Let d = discriminant
d = b^2 - 4ac
Let a = 2, b = 4 and c = -9
We now plug and chug.
d = (4)^2 - 4(2)(-9)
d = 16 - 8(-9)
d = 16 + 72
d = 88
