the formula is a_{1}+(n-1) d
so a_{1} would be the first number in the sequence, which would be 13 in problem 9.
13+(n-1)d
then you put in n, which is 10 (it represents which number in the sequence you're looking for, for example 16 is the second number in the sequence)
13+(10-1)d
then you find the difference between each number, represented by d which in this case is 3
13+(10-1)3
13+(9)3
13+27=
40
Answer:
$7
Step-by-step explanation:
a) First let's organize the information:
The cage cost $40
two bowls cost the same
the total was $54
b) Put it as an equation
40+x+x= 54
c) we will subtract 54-40 and get 14
d) divide 14 by 2 and get 7 for the cost of each bowl.
Hope you understand it ;)

He is not
In school B, the angle representing the sector of students that like tigers is 90 degrees while in school A, the angle representing the sector of students that like tigers is larger than 90 degrees. this is determined by perusing the images visually.
Step-by-step explanation:
Please find the complete question in the attached image
Pie chart is a graph used to represent numeric information. the sum of angles in a pie chart equals 360 degrees. the pie chart is usually separated into sectors to represent numeric information
the angle representing the students that like tigers in school A = 0.5 x (360 - 60) = 150 degree
The answer is C. You would take -18 and divide by two and get -9. Then square this to get 81. That is your answer, hope this helps!
