Answer:
30 inches squared
Step-by-step explanation:
First, find the area of the entire frame using length times height. 9*6 is 54 inches squared. Then, find the area of the middle space the same way. 6*4 is 24 inches squared. Lastly, subtract the middle from the entire frame's area. 54-24 is 30 inches squared.
Answer:
Step-by-step explanation:
The given above is an arithmetic sequence with first term equal to 3 and the common difference equal to 4. That is from 7 - 3 = 11 - 7 = 15 - 11. The nth term of an arithmetic sequence is given by the equation,
an = a1 + (n - 1) x d
Substituting the given,
an = 3 + 4(n - 1)
thus, the answer is the fourth choice.
Answer:
NOT PROPORTIONAL
Step-by-step explanation:
The given two fractions are:
and
.
Proportional fractions are those which have the same value when to reduced to the simplest form.
Consider two fractions
and
.
We say they are proportional if
.
Or, if
then we can say the fractions are proportional.
Here the fractions are:
and
.
LHS: 5 X 10 = 50.
RHS: 8 X 8 = 64.
Clearly they are not equal. So, we can say these two fractions are not proportional.
