Answer:

since a,7,b,23,c are in A.P.

first term t1=a

second term t2=7

common difference (d)=7-a

forth term t4=a+3d

23=a+3(7-a)

23=a+21-3a

23=21-2a

2a=21-23

a=-2/2=-1

common difference =7-a=7--1=8

third term =a+2d=-1+2×8=15

:.b=15

5th term =c

a+4d=c

c=-1+4×8=31

a=-1

b=15

c=31

Help with number 13. . . . . .
kvasek [131]

Answer:

6A, D

Step-by-step explanation:

So, you have A = b*h. The general formula for the area of a triangle. Then, we double the base and triple the height. We then get the expression (2b)*(3h).

Since it is multiplication, we can multiply 2 and 3 to get 6 and get 6*b*h.

Though, we know b*h is just A so we get 6A.

You play a game that involves spinning the money wheel shown. you spin the wheel twice find the probability that you get more th
olga2289 [7]
There are 24 segments on the wheel in total. 1 segment is the $500 and 2 are the bankruptcy spaces. You would then multiply the two fractions 1/24 and 2/24 (the chances of getting each result) to get the answer. 1•2=2 and 24•24=576 making the fraction 2/576. Then you would simplify by dividing both sides by 2 which equals the final answer 1/288.
