Okay, so we know that the perimeter of the square is 20. Since a square has 4 equal sides to find the length of one side, 20/4. Each side is equal to five. Look at each of the coordinates and put them respectively into a graph in your mind. w(3,2) (bottom left) x(3,7) (top left) Y(8,7) (top right). Now we know we need to find the bottom right coordinate. Being that both of the coordinates on the left have the same x value we can justify that the coordinates on the right have the same X value also. we can say this same thing for the y coordinate. Since both coordinates on the top of the square have the same Y value, we can justify that the coordinates on the bottom have the same Y value. So taking the coordinates we now are the same, the answer is Z(8,2). We can check his by seeing if the distance if five from each of the adjacent coordinates. If you have any questions comment below.
Answer:
2a.
2b. 78
Step-by-step explanation:
For 2a, all the squares are similar and this shape forms a cube. Count the boxes for the length and width for 1 square to find the dimensions 3 for the width and 3 for the length. Find the area of that square by doing length*width which in this case is 3 x 3 = 9. Then multiply 9 x 6 because there are 6 squares and get an answer of 54.
For 2b, we know the dimensions for the rectangle 5cm will be the longer side and 3cm will be the shorter side. Find the area of one rectangle using length*width. For one rectangle we get 5 x 3 = 15. Next, we know the square will have sides of 3cm. Do length*width to get the area of one square which is equal to 9. Now that we have the areas for the squares and rectangles, multiply 15 (the area of one rectangle) by 4 because there are 4 similar rectangles. After doing this we get 60. Next do the same thing with squares but multiply by 2 because there are 2 squares. After doing this we get 60 + 18 for the surface area of the figure. 60 + 18 = 78.
Answer:
D
Step-by-step explanation:
The geometric sequence formula is:
An=a*r^(n-1)
An= nth term of the sequence
a= first term of the sequence. In this case, the amount Monica had in the first month
r= common ratio. In this case, is the interest rate, which is constant in all months.
n= number of periods
Following this equation, option A and B are not correct because "a" the first term of the sequence is $225.
It is not option C because Monica will have her first $225 plus interest not only the interest she gained, then the common ratio should be a number greater than 1.
It is option D and let´s proved it:
A6= 225*(1.04)^(6-1)
A6=225* (1.21665)
A6=$273.746
A6=$273.75
