Mathematics

TEA [102]3 years ago

Answer:

y = 102, z = 67

Step-by-step explanation:

The angles 113 and z form a straight angle and are supplementary, thus

z = 180 - 113 = 67

The sum of the 4 interior angles of a quadrilateral = 360°

Sum the interior angles and equate to 360 for y

y + 102 + 89 + 67 = 360, that is

y + 258 = 360 ( subtract258 from both sides )

y = 102

All circles are similar because all circle have same shape.

However Two circles are congruent , if and only if their radii are congruent.

In our question we are asked when are all circles similar given if their radii are congruent.

So we can say this statement is false because no matter the radii are congruent or not  , two or more circles are always similar because of their same shape no matter what the measure of their radii is. Only if we are asked when they are congruent, we will consider the radii part.

Answer is false.

In this question they've given us the formula and they just want us to plug in the numbers and get the value.


P is the original value, P=$600


r is the depreciation rate, r=10%=0.1


t is the time in years, t=2


A = P(1-r)^t = 600(1 - 0.1)^2 = 600 \cdot .9^2 = 486


Answer: $486
