If a girl in a bikini has walked 4 KM in 10 minutes, How many kilometers does she walk in 3 years?
Mashutka [201]

Answer:

631139.04 kilometers in 3 years

Step-by-step explanation:

Let x = how many kilometers she walk

y = time (minutes)

Since she walks 4km in 10 minutes.

x = 4, y = 10

(4,10)

But how many minutes if she walk only a kilometer? Divide x and y by 4.

(1,2.5)

She walks a kilometer under 2.5 minutes.

Now finding rate of changes.

\displaystyle \large{m =  \frac{10 - 2.5}{4 - 1} } \\  \displaystyle \large{m =  \frac{7.5}{3} } \\ \displaystyle \large{m =  2.5}

Since m = 2.5

and of course, the function should be proportional so the equation should be y = mx.

\displaystyle \large{y = 2.5x }

Since time should be minutes instead of years.

Since 3 years = 1577847.6 minutes

\displaystyle \large{1577847.6 = 2.5x}

Divide both sides by 2.5

\displaystyle \large{ \frac{1577847.6}{2.5} = x} \\ \displaystyle \large{631139.04 = x }

Which shapes are quadrilaterals?
lubasha [3.4K]

Hey there! I'm happy to help!

A <u>quadrilateral </u>is any polygon (enclosed shape) with four sides. Let's see what each of these shapes are.

  1. Scalene right triangle - the prefix <u>tri-</u><u> </u>means <u>three  </u>(tricycle, tripod, triple, etc.<u>),</u> and all triangles have three sides, so this is not a quadrilateral.
  2. Obtuse scalene triangle - once again a triangle, so not a quadrilateral.
  3. Isosceles right triangle - would you look at that, another triangle! Not a quadrilateral.
  4. Hexagon - a hexagon is a six-sided polygon (<u>hex=six)</u>, so this is not a quadrilateral.
  5. Pentagon - a pentagon is a five-sided polygon (<u>pent=five, </u>like Pentatonix!). Not a quadrilateral
  6. Right trapezoid - a trapezoid is a quadrilateral with at least one pair of parallel sides!
  7. Venn diagram - a Venn diagram is a compare and contrast chart made of two overlapping circles (ZERO sides), so this is not a quadrilateral.

So, the only shape on your list that is a quadrilateral is 6. right trapezoid.

Have a wonderful day! :D

How do I solve this equation 144=-12(x+5)
Papessa [141]
First you distribute the -12 to the (x+5) getting 144=-12x-60.

Next you add 60 to each side getting 204=-12x

Then you divide each side by -12 getting -17=x, which is the answer.<span />
