Tim is going to an amusement park that cost 30.00 to get into.Treats like cotton candy carmel apples and funnel cakes cost 2.00
larisa86 [58]

Answer:

x = 16 treata

Step-by-step explanation:

Let us represent x = Number of treats that Tim can buy

We are told that: Tim does not want to spend more than $62.00 in all.

= Time wants to spend less than or equal to $62.00

Tim is going to an amusement park that cost $30.00 to get into.Treats like cotton candy carmel apples and funnel cakes cost 2.00 dollars each .

Therefore, our inequality equation =

$30.00 + $2.00 × x ≤ $62.00

30 + 2x ≤ 62

Solving for x

30 + 2x ≤ 62

2x ≤ 62 - 30

2x ≤ 32

x ≤ 32/2

x ≤ 16

Hence, Tim can buy no more than(less than or equal to ) 16 treats

The eight term of a geometric progression is given by Sn= -[-3(sin^2x + cos^2x)^n + In e. Find the first term and common ratio.​
igor_vitrenko [27]

Answer:

Step-by-step explanation:

Sn= -[-3(sin^2x + cos^2x)^n + In e.

sin^2x + cos^2x = 1  and ln e = 1, so

Sn = -(-3)^n + 1

When n = 8

this = -(-3)^8 + 1

The lenght of a turtles shell z, in millimeters, is related to the turtles age in years a , as described by the equation below.
puteri [66]

Answer:

B, C , F

Step-by-step explanation:

The age multiplied 55, so the shell grows at rate of 55mm per year

in fact if the age is 2 we have (55 x 2) = 55 + 55

if 3 = (55 x 3) = 55 + 55 + 55

and so on

When the turtle is hatched the shell is 37 mm in lenght.

In fact, if we substitute 0 to a, we have

s = (55 x 0) + 37

s = 37

when the turtle is 1 year old, the shell is 92 mm in length.

in fact if we substitu a with 1, we have

s = (55 x 1) + 37

s = 55 + 37

s = 92
