To take a taxi, it costs \$3.00 plus an additional \$2.00per mile traveled. You spent exactly \$20 on a taxi, which includes the \$1 tip you left. How many miles did you travel

Answers

 A taxi ride where the total fare is $3, $2 for every mile travelled plus a $1 tip and the original cost of $20.

First write a formula that expresses the cost of the ride:

Total cost= Flat fee + Mileage + Tip

Now let's drop in what we know:

20= 3+2 (miles) +1 - we know the total cost is 20, the fee of 3, the tip of 1 and the cost per mile of 2. The only thing we don't know is the number of miles. So let's solve for that.

Subtract 3 and 1 from both sides to get:

16=2(miles)

Divide both sides by 2:

8=miles
Therefore, you traveled 8 miles.

What is the general form of the equation for the given circle centered at O(0, 0)?​

Answers

Step-by-step answer:

The general form of an equation centered at O(0,0) is given by

x^2+y^2=r^2

where r is the radius, (x,y) is any point on the circumference.

If B(4,5) lies on the circumference, then we can find the radius of the circle by substitution:

4^2+5^2=r^2

=>

r^2 = 16+26 =41

Hence the equation of a circle centred at O(0,0) and B(4,5) on its circumference is

x^2 + y^2 = 41

Answer:

Option B for plato is the correct answer

Step-by-step explanation:

B.  x2 + y2 − 41 = 0

sean and leah are playing a computer game. sean scored 72,491 points. leah scored 19,326 points more than sean. how many points did leah scored? tape diagram

Answers

Answer:

Leah scored 91,817 points.

Step-by-step explanation:

Sean and Leah are playing a computer game.

Let Leah scores x points.

Sean scored 72,491 points.

Leah scored 19,326 points more than Sean.

So, x=72491+19326

= 91817

Hence, Leah scored 91,817 points.

If Sean scored 72,491 points and Leah scored 19,326 more  then you add 72,491 and 19,326 to get your answer of 91,817

Assuming that the traps stay the same, we know that the number of moths they catch will be relative to the size of the population of moths. From this, we can see that the trend in the population of light moths is a steady decrease from year to year, and the trend in the population of the dark moths is a steady increase over the same time period.

Since the trees have been darkened by industrial pollution (they have black smoke on them), we know that the dark moths camouflage better than the light moths. Because of this, the white moths get eaten by predators more often and their population goes down gradually; the dark moths, however, camouflage easily, and their population goes up since they get eaten less often.

If the environment were cleaned up, the light moths' population would increase (since they camouflage better on clean trees), while the dark moths' population would decrease (since they camouflage better on dirty, polluted trees).

How many triangles can you construct with the angle measures of 50, 70, and 100?

Answers

Answer:

0

Step-by-step explanation:

You can't construct any triangles with those angles. Because when you add all the angles of a triangle, it has to add up to 180. But when we add 50,70, and 100, it equals 220. So you can't construct any triangles.

Hope this helps. (If it does, please mark me brainliest)
