Answer:
The sum of the first six terms is
Step-by-step explanation:
Given series is 32-8+2-0.5+...
We may write
Let
Common ratio
Therefore the common ratio is
Therefore given sequence is of the form of Geometric sequence
The nth term of the geometric sequence is
First to find the 5th and 6th term
That is substitute n=5 and n=6 ,a=32 and in above equation we get
Therefore
Therefore
Therefore the sum of the first six terms is
Therefore the sum of the first six terms is

Step-by-step explanation:
all triangles add up to 180*, easy to reverse the math
uwu
Answer:
57
Step-by-step explanation:
There's three shapes, 2 triangles and 1 rectangle.
1. To find the area of a rectangle multiply the legth x width, so 5*2, which is 10.
2. To find the area of a traingle multiply the length and width, and then divide that by two. For the smaller triangle do 6*5, which is 30, and divide that by 2 for 15.
3. The big triangle shows the length of one side but not on the other. Because the length of the rectangle is the same on both sides, and the length 3 and 5 are on the same line, the other length of the large triangle is 8.
4. 8*8 is 64, and dividing that by 2 is 32.
5. Add all of the numbers: 10+15+32, which is 57.

C) twenty-eight and nine tenths
<u><em>Explanation:</em></u>
We have two parts here, the whole number and the decimal part.
<u>1- for the whole number,</u> it is read normally as counting numbers. Therefore, 28 is read as twenty-eight
<u>2- for the decimal part, </u>it is read based on the place-value of the number. We know that the first number after the decimal point is in the tenth position. This means that 0.9 is read as nine tenths
<u>Combining the two,</u> we would conclude that 28.9 is read as twenty-eight and nine tenths
