Answer:
The answer would be 9
Step-by-step explanation:
Step 1: Our output value is 30.
Step 2: We represent the unknown value with $x$.
Step 3: From step 1 above,$30=100\%$.
Step 4: Similarly, $x=30\%$.
Step 5: This results in a pair of simple equations:
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
Step 7: Again, the reciprocal of both sides gives
Therefore, 30% of 30 is 9
-7 is term in the given expression

3/10 is the Probability of not Drawing Blue Marbles
Step-by-step explanation:
Blue Marbles = 7
Green Marbles = 2
Red Marbles = 1
Total Marbles = 7 + 2 + 1 = 10
Probaility of Drawing Blue Marbles = 7 /10
Probability of not Drawing Blue Marbles = 1 - Probaility of Drawing Blue Marbles
= 1 - 7/10
= 3/10
or
Probability of not Drawing Blue Marbles = Probability of drawing Green or Red Marbles
= 2/10 + 1/10
= 3/10
3/10 is the Probability of not Drawing Blue Marbles
First we do what’s in the parentheses.
7 • 10 - 5 = 70 - 5 = 65
Then we do exponents. We don’t have any so we skip this step.
Then we do multiplication and division.
65 • 0.0007 = 0.0455
We don’t have any addition or subtraction so we skip this step.
The solution is 0.0455.
4 + 3/5 = 23/5 and
2 + 1/3 = 7/3 get a common denominator = 15 ....so....
23/5 = 69/15 and
7/3 = 35/15
So
69/15 - 35/15 =
34/15
