Answer:
Third side is 15cm. Perimeter is 37cm.
Step-by-step explanation:
In a triangle sum of two sides is always greater than third side. Two sides of a isosceles triangle are equal.
So if the third side is 7cm
7+7=14cm which is less than 15 cm.
hence third side is 15 cm as
15+15=30cm which is greater than 7cm
15+7=22cm which is greater than 12cm
then
perimeter=15+7+15=37cm
Answer:
2%
Step-by-step explanation:
Chloe's simple interest for 1 year is $4. You can get this by subtracting the amount she invested from the total amount she got after one year.
Now that we know the simple interest, we can now get the simple interest rate or<em> simple percent interest per year </em>by dividing $4 by $200.
Let's change 0.02 into a percentage.
This means that every year, her investment will earn a <em>2% simple interest.</em>
Answers: 0.08 and -0.08; 0.09i and -0.09i.
When taking square roots, we take the positive and negative answers. This gives us the first answer.
For the second answer, we rewrite -0.0081 as a complex number:
The width of a line can't be measured.
When we draw it, we give it some length just so that we can
see it on the graph. But mathematically, a line has only one
dimension and that's length. It has no mathematical width.
