Answer:

We know that the equation for the speed is:

Speed = Distance/time.

First, we know that he walks 2 miles in 15 minutes.

distance = 2miles

time = 15 minutes

Then his speed in that interval is:

Speed = (2 mi)/(15 min) = (2/15) miles per minute.

Now, at this same speed, he wants to walk 3 more miles. And we want to find the equation that represents how much time she needs to walk 5 miles (the 2 first miles plus the other 3 miles)

We use again the equation:

Speed = Distance/Time

But we isolate Time, to get:

Time = Distance/Speed

Where:

Distance = 5 miles

Speed = (2/15) miles per min

Time = (5 miles)/((2/15) miles per min) = 37.5 minutes

She needs 37.5 minutes to walk the 5 miles.

What is the probability of rolling a “4” on a fair 6-sided die and flipping a heads on a fair coin?
Sauron [17]

Answer:

Die: 16. 2/3%

Coin: 50%

Step-by-step explanation:

Well rolling a 4 on a 6 sided die is 1/6.

To make that a percent we first make it a decimal.

1 ÷ 6 = .16666 repeating

To make this a percent we move the decimal place 2 times to the right.

16.2/3%

The chance of flipping a heads on a fair sided coin is 50% because there are two sides with a 50/50 chance of being either.

<em>Thus,</em>

<em>for rolling a 4 on a 6 sided die there is a 16.2/3% chance and a 50% for flipping a heads on a 2 sided coin.</em>

<em>Hope this helps :)</em>

You joined an online coupon club. You earned 100 bonus points just by signing up. Each month you use the site, you earn another
Blababa [14]
So,

I'm assuming you want me to make a formula for figuring your points after any given month assuming that you use the site at least once a month and you don't spend your points.

After one month, you will have your base 100 points plus an additional 10 points.

100 + 10 = 110

After two months, you will have gained an additional 10.
110 + 10 = 120

We can put this into a function, where P is your points, and m is the number of months you use the site.

P(x) = 100 + 10m

So after 500 months, you will have:

P(x) = 100 + 10(500) = 5100 points!

This is identical with:
y = 100 + 10m

and

y = 10m + 100

So this can be graphed as a linear equation/function with a y-intercept of 100 and a slope of 10/1.

Cristiano is saving money to buy a bike that costs $189, He saved $99 so far. He plans on saving $10 each week. In how many week
yuradex [85]

Answer:

Cristiano will have enough money to buy bike in 9 weeks.

Step-by-step explanation:

Given:

Cost of the bike = $189

Money saved = $99

Money saving each week = $10

We need to find the number of weeks will he have money to buy bike.

Solution:

Let the number of weeks be 'x'.

Now we can say that;

Money saved  plus money saving each week multiplied by number of weeks is equal to cost of the bike.

framing in equation form we get;

99+10x=189

Subtracting both side by 99 using subtraction property of equality we get;

99+10x-99=189-99\\\\10x=90

Dividing both side by 10 using division property of equality we get;

\frac{10x}{10}=\frac{90}{10}\\\\x=9\ weeks

Hence Cristiano will have enough money to buy bike in 9 weeks.
