Answer:
39
Step-by-step explanation:
dividing both sides by -4, we get:
this means, each term is its previous term divided by -4.
now we can construct the sequence as follows:
Answer: the last term is -1/32
One field is 25 + 45 + 25 + 45 = 140 feet
Second field is 40 + 60 + 40 + 60 = 200 feet.
Therefore, all together, the two fields are 340 feet in perimeter together
Answer:
b. 40,960
Step-by-step explanation:
There is probably some equation you could do for this but I find it simpler just to take 10 and multiply it by 2 and then keep multiplying the answers by 2 twelve times so:
10*2=20
20*2=40
40*2=80
80*2=160
160*2=320
320*2=640
640*2=1280
1280*2=2560
2560*2=5120
5120*2=10240
10240*2=20480
20480*2=40960
The value of a from the given figure is 105 degrees
<h3>Circle theorem</h3>
From the given theorem, the quadrilateral is inscribed in a circle. For the quadrilateral, the sum of the opposite angle is supplementary. Hence;
a + 75 = 180 (supplementary)
Subtract 75 from both sides
a + 75 - 75= 180 - 75
a = 180 - 75
a = 105 degrees
Hence the value of a from the given figure is 105 degrees
