Answer:
Solution given:
diagonal 1=AC=5+5=10 units
diagonal 2=BD=4+5=8units
area of polygon (rhombus)=½*(diagonal 1*diagonal 2)
=½(10*8)=40square units
Area=<u>40square units</u>
Answer: The percentage change in GDP over this time period is about 4.14%.
Step-by-step explanation:
Given: The approximate nominal GDP in 2010 = $14.5 trillion
The approximate nominal GDP in 2011 = $15.1 trillion
Now, the change in GDP over this period =
The percentage change in GDP over this time period will be :
Hence, the percentage change in GDP over this time period is about 4.14%.
Answer:
21, 42, 63, 84
Step-by-step explanation:
3x7=21
Because of this all multiples of 21 will be common multiples of 3 and 7
Answer:
a(31) = 84
Step-by-step explanation:
The first term, a(1) is 204, and the common difference is 4. That is, each new term is 4 less than the previous term.
The rule governing this arithmetic sequence is
a(n) = 204 - 4(n - 1)
and so the 31st term is
a(31) = 204 - 4(30) = 84
Answer: x = 0
Step-by-step explanation: To solve for <em>x</em> in this equation, our first step is to simplify the left side by distributing the 10 through both terms inside the parentheses.
When we do that, we get 10 times x which is 10x
and 10 times -2 which is -20.
So we have 10x - 20 = -20.
Adding 20 to both sides, we get 10x = 0.
Divide both sides by 10 and <em>x = 0</em>.
