It costs $48.05 to get into the team park and then, $1.50 for every ride Michael goes on. He spent a total of $87.05. Write and solve an equation to find the number of rides that Michael went on.

Answers

Answer:

48.05+1.5x=87.05

Step-by-step explanation:

48.50 is the one time entry fee, and you add that to how much he spent on rides. you calculate that by taking the cost per ride and multiplying it by how many rides he went on, but since we do not know that number, we use algebra:

subtract 48.05 from each side to get this:

1.5x=39

now, you want to get the x by its self, so you divide each side by 1.5 to get this:

x=26

so, michael went on 26 rides :)

The entry fee is 48.05 so the first number in the equation should be 48.05. Every ride cost 1.50 though but we don’t know how many rides he got on but the we will find out. The first step is to write the equation which it 48.05+1.50a=87.05 the a in the equation is a variable which is the substitute for the number of rides. Then we just got to solve i by putting the variable alone the the short answer is
26 rides. MARK ME AS BRAINLYIST PLZZZZZZ

Im having trouble with a answer its about probability P(F) but I dont understand it that much

Answers

Answer:

[tex]1/10[/tex]

Step-by-step explanation:

This book doesn't really explain this specific probability question clearly. The circle has 10 small triangles. F is one triangle. We can say that F occurs every 10 small triangles so the ratio would be:

[tex]1/10[/tex]

For the second one, we can have D or B, which both have 1 triangle each. We can say that D or B can have 2 triangles out of 10 so the ratio would be:

[tex]2/10--> 1/5[/tex] We can simplify 2/10 to 1/5.

For the third one, we have 3 vowels. So the ratio would be [tex]3/10[/tex]

Lucy deposited $1,000 into an account that earns 2.5% compound interest, compounded yearly. How much interest will Lucy earn after 8 years?

my answer is $1218.40 but supposedly it's wrong.

Answers

Answer:

the balance in the account after 20 years is $819

Step-by-step explanation:

The computation of the balance in the account after 20 years is shown below:

As we know that

Future value = Present value × (1 + rate of interest)^number of years

= $500 × (1 + 2.5%)^20

= $500 × 1.025^20

= $819

Hence, the balance in the account after 20 years is $819
