Answer: 24cm²
Step-by-step explanation:
Let square with length 5cm be represented with A, and square with 7cm be represented with B.
Area of a square is L²
Square A will have an area of 5² = 25cm²
Square B will have an area of 7² = 49cm²
Total area between the two squares will be = Area of Square (B - A)
i.e.
Total Area = 49cm² - 25cm² = 24cm²
Answer: 4.6 is the answer to 1.38 divided by 0.3=4.6
Answer:
20 and 3/7
Step-by-step explanation:
In
order to solve for a nth term in an arithmetic sequence, we use the formula
written as:<span>
an = a1 + (n-1)d
where an is the nth term, a1 is the first value
in the sequence, n is the term position and d is the common difference.
First, we need to calculate for d from the given
values above.
<span>a3 = 20.5 and a8 = 13
</span>
an = a1 + (n-1)d
20.5 = a1 + (3-1)d
</span>an = a1 + (n-1)d
13 = a1 + (8-1)d
<span>
a1 = 23.5
d = -1.5
The 11th term is calculated as follows:
a11 = a1 + (n-1)d
a11= 23.5 + (11-1)(-1.5)
a11 =
8.5</span>
