Answer:
c
Step-by-step explanation:
c=2*22/7r
440=44/7r
440*7/44=r
70=r
d=2r
d=2*70
d=140 cm
Answer:
$356
Step-by-step explanation:
So if they are 400 students we need to:
0.89*400=$356
Let's say that Stan invested $1500 at 6%. To find how much he invested at 4.5% would be 5000 - 1500 = $3500. Now we have a pattern. Now let's say stan invested x dollars. Even though it is unknown, we can set up how much is left. So subtract x from 5000 or 5000 - x which is C
Independent, means the first event won't affect the second event.
The independent events would be :
A, B, E, F
I will have "x" represent the unknown number, or you could use a "?", doesn't matter.
[8 is less than or equal to (≤) the quotient (÷) of a number and -4, so the number is being divided by -4]
If you need to solve this, you need to isolate/get the variable "x" by itself in the inequality:
Multiply -4 on both sides to get rid of the fraction and get "x" by itself
When you multiply/divide by a negative number, you flip the sign (< >)
-32 ≥ x [-32 is greater than or equal to x, or x is less than or equal to -32]
