No. One side can be higher than the other side, therefore, a trapezoids height isn't always the distance between the 2 bases.

Mr. and Mrs. Yeager want to buy a home valued at $320,000. If they have 15% of this amount saved for a down payment, how much have they saved? a.$480 b. $4,080 c.$4,800 d. $48,000 Solution 1 If they have 15% of this amount saved for a down payment, then they saved 48000 dollar. So option D)$48,000 is correct.

### What is the fundamental principle of multiplication?

Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.

We are given that Mr. and Mrs. Yeager want to buy a home valued at $320,000. If they have 15% of this amount saved for a down payment, then 15% =15/100=0.15 Therefore, we get; 0.15 (320000)=48000 If they have 15% of this amount saved for a down payment, then they saved 48000 dollar. So option D)$48,000 is correct.

Question
In a certain area of Brazil, deforestation is currently the most critical Socio economic problem. The area of a certain rain forest is currently 1156.25 square miles. after every year, the area of this rain force decreases by 2% which of the following statements is correct A- deforestation problem is an example of exponential growth B- The growth or decay rate for the area of the rainforest is 0.2 C- The function of equals 1156.25(1 -0.02 )^t D- in less than a century the rain forest will be completely wiped out E- in about 35 years the area of the rain forest will be cut by more than half F-The domain of the function that model the deforestation problem above is 0<_t<_100 (less than or equal to <_)
Solution 1

A is INCORRECT because here we have degrowth and growth

B is INCORRECT because the decay factor is 2% or 0.02 , not 0.2

C is CORRECT, the function is which is used to calculated the area of rainforest at time t is given by 1156.25(1 -0.02 )^t

D is INCORRECT, if we plug in t=100 in the above equation , we get = 1156*(1-0.02)^100 = 153 square miles of forest. So it will not be wiped out

E is CORRECT, if we plug in t =35, we get = 1156*(1-0.02)^35 = 570 square miles. So more than half will be cut in 35 years

F is INCORRECT becuase domain goes beyond 100 years as shown by option D

So, correct options are C and E

Question
Jon performs 3 transformations on a pentagon. First, he reflects it over the x-axis. Then, he translates it 3 units to the left and 4 units up. Finally, he reflects the image over the line x = 1. Are the original and transformed images congruent? Justify your answer.
Solution 1
Reflection and translation do not change the dimensions (or angles) of the figure.

The original and transformed images are congruent.
Solution 2

yes; Reflections and translations are rigid motions. Rigid motions preserve the size of the original image.

Question
What precentage of 538894.80 is total interest
Solution 1
538,894.80 = 53,884,980%

Question
What rate of simple interest is needed for $700 to double, in 3 years? Solution 1 Let the rate required to double the amount be r. To solve the question we use the formula: A=p(1+r)^n A=future amount p=principle r=rate n=time from the information given: A=1400, p=$700, n=3 years,
plugging the values in the equation we get:
1400=700(1+r)^3
simplifying and solving for r we get:
2=(1+r)^3
squaring both sides:
√2=1+r
hence
r=√2-1
r=1.414-1
r=0.414
=41.4%

Question
Suppose that on a coordinate plane a hexagon is reflected across the x-axis. Compare the area of the original hexagon to the area of the transformed figure. Justify your answer
Solution 1

The areas will be the same.

A reflection is called a rigid transformation.  It preserves congruence of sides and of angles.  This means that reflecting the hexagon across the x-axis will not in any way change the size or shape of the figure, just the positioning.

Since the size and shape are the same, the areas will be the same.
