The first term of an arithmetic sequence is 123 the common difference is 12 and the sum is 1113 how many terms are in the series

S_A_V [24]

You can use this formula of arthenatic series to find sum to get the number of term
sum= n÷2 (2a+(n - 1)d)
n= number of tern = n
a= first term =
d= common difference
sum= 1113
you can find the number of series by putting in them

Miriam is going to the county fair. Each ride ticket costs $2 and admission costs $7. Miriam has $25 to spend at the fair.

Talja [164]

Answer:

Step-by-step explanation:

Given data

Ride ticket= $2

Admission= $7

Amount= $25

We want to find the greatest number of rides

let the number of rides be x

The expression to describe how she spends the amount is given as

y=7+2x

for y= 25, let us find x

25= 7+2x

25-7= 2x

18=3x

x= 18/2

x= 9

Hence the number of rides is 9

The triangular prism has a volume of 27 cubic units.

Mashcka [7]

For this case we have the following relationship between the volumes:
$V2 = k ^ 3 * V1
$
Where,
V2: Volume of the triangular prism after applying the scale factor on each side
V1: Original volume of the triangular prism
k: scale factor
Substituting values we have:
$V2 = (\frac{1}{3})^3(27)$
Rewriting:
$V2=\frac{1}{27}(27)$
$V2=1$
Answer:
the volume of the prism if each side is dilated by a factor of 1/3 will be
V = 1 cubic unit
