Answer:
each kid gets 1.42857142857th of the cupcake
Step-by-step explanation:
10/7=1.42857142857
Answer:
The fifth term is 7
Step-by-step explanation:
Looking at the graph
we have the ordered pairs
(1,5),(2,5.5),(3,6),(4,6.5),(5,7)
so
Let
The common difference in this arithmetic sequence is 0.5
The value of the fifth term is a_5
therefore
The fifth term is 7
Evaluating the given sequence, it is evident that the next number is twice the number prior to it. Thus, the given is a geometric sequence with first term (a1) equal to 1 and common ratio of 2. The geometric series may be calculated by the equation,
Sn = a1 x (1 - r^n) / (1 - r)
where Sn is the sum of n terms in this case, n = 11.
Substituting the known values,
<span> Sn = 1 x (1 - 2^11) / (1 - 2) = 2047
</span>
Thus, S11 is 2047.
Answer:
x = 9 cm
create proportional equation:
Answer:
a is 31 b is 38 x is 133. Y is 47
Step-by-step explanation:
A is 31 because the other side is 31. we know the sides are the same because of the markings. B is 38 because the other side is 38 we know that because of the markings which mean its the same. X is 133 Y should be 47 because ALL ANGLES IN A QUADRILATERAL IS EQUAL TO 360. 133+133=266 360-266 is 94. 94 is for both angles so we need to divide by 2 the answer for Y is 47
