Answer:
175.1
Step-by-step explanation:
Find the area of the semicircle:
(pi • radius²) / 2. [Radius is half of diameter]
(3.14 • 4²) / 2
(3.14 • 16) / 2
(50.24) / 2
25.12
Find the area of the parallelogram:
(base • height)
(30 • 5)
150
Add the areas of both shapes to get total area
25.12 + 150 = 175.12, round to the nearest tenths, 175.1
Hope this helps!
First of all, let's derive all the quantities. We know that Jermaine has tokes. So, if you have 4 more tokens, it means that you can start from this quantity, and add 4. In formula Karen has
tokens.
By the same logic, 5 fewer than a certain quantity means to subtract 5 from that quantity, so Raul has
tokens.
Now we're ready to write the ratio between the two numbers: simply put Karen's tokens at the numerator and Raul's tokens at the denominator and substitute and with the expressions we just found:
Obviously, since we don't know the value of , we can't say exactly how many tokens anyone has, or computing the ratio numerically, but only express it in terms of .
Let your age be 'X'
Then the age of your brother will be
The age of your sister is 10, but can also be written as an expression (since it is the age of your brother +6)
Now we get the following equation:
Subtract 6 from both sides
Multiply by 3
Hence, the answer on your question (which is your age) is 12.
