Taylor earns $5 each time she walks her neighbor's dog.she has already earned $25.write and solve an equation to find out how many more times taylor needs to walk the dog to earn enough to buy a bike that cost $83.

Answers

Answer:

Equation: $83=5w+25 and 12 walks more

Step-by-step explanation:

Here is an equation: $83=5w+25

The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)

The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.

The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)

To solve:

83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone

58 = 5w –– Divide both sides by 5 to get w alone

11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)

Check:

83=5w+25 –– Replace w with 12

83=5(12)+25 –– Multiply

83=60+25 –– Add

83=85 –– This shows she will have $2 left over

An event organizer found that 70% of young couples prefer to have indoor weddings instead of outdoor weddings. You want to survey three randomly chosen couples and use the results to find the estimated probability that all three couples prefer indoor weddings.
This scenario can be simulated by generating a set of three numbers using a number generator with numbers
. The numbers
would represent couples who prefer indoor weddings. If all three numbers in the set are in the range
, it would mean that all three couples prefer indoor weddings.

Answers

Answer:

1. 0-9

2. 0-6

3. 0-6

Step-by-step explanation:

This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

(ik you might not need this anymore, but I'm hoping it proves useful to others)

All three numbers in the set are in the range it would mean that all three couples prefer indoor weddings is  0-9, 0-6 and 0-6.

We have given that,

An event organizer found that 70% of young couples prefer to have indoor weddings instead of outdoor weddings.

What is the range?

The Range is the difference between the lowest and highest values.

This scenario can be simulated by generating a set of three numbers using a number generator with numbers 0-9. The numbers 0-6 would represent couples who prefer indoor weddings. If all three numbers in the set are in the range 0-6, it would mean that all three couples prefer indoor weddings.

An online shopping club has 13000 members when it charges ​$7 per month for membership. For each ​$ monthly increase in membership​ fee, the club loses approximately 500 of its existing members. Write and simplify a function R to represent the monthly revenue received by the club when x represents the price increase.

Hint: Monthly revenue​ = # members•monthly fee

Just a answer with work will do, ill brainliest the best one.

Answers

Answer:

The function is: [tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Step-by-step explanation:

Total members=13000

Membership charge per month=$7

Increase in Membership charge per month=$1

For each $1 monthly increase in membership fee, the club loses approximately=500 members

For 1 month, 1 dollar decrease is 500 × 1

For x months, the decrease in the members is 500 × [tex]x[/tex] =[tex]500x[/tex]

The increase in membership fee is 7 + [tex]x[/tex]

After that,

Monthly revenue = Number of members × Monthly fee

Monthly revenue = [tex](13000-500x)[/tex] × [tex](7 + x)[/tex]

[tex]R(x)=(13000-500x)[/tex] × [tex](7 + x)[/tex]

Answers

Answer: B -4

Step-by-step explanation:

Value of coefficient of the squared term in the parabola's equation = -4

Correct option is B.

What is parabola?

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.

Given,

Vertex of parabola (h,k) = (3, 5)

y = 6 for x = -1

Parabola opens horizontally left side

Vertex-form equation of parabola

x = a(y - k)² + h

-1 = a(6 - 5)² + 3

-1 = a(1) 3

a = -4

Hence, -4 is value of coefficient of the squared term in the parabola's equation.

Jonathan is making his favorite pasta dish. He serves his mom 1/12 of the pot of pasta and his brother 1/6 of the pot. How much of the pot is left over? PLS HELP I HATE MATH

Answers

Answer:

3/4 of the pot left.

Step-by-step explanation:

If the mom eats a 1/12 of the pot and then the brother also eats a 1/6 of the pot, then it is 9/12 left of pasta still. The reason for that is since 1/6 is equivalent to 2/12 so 1/12 plus 2/12 is 3/12, and if u subtract 3/12 from 12/12 it will give you 9/12 which can be simplified to 3/4 left of the pot.
