If 5 miles = 8km. how many km in 250 miles?

Answers

Answer 1

Answer:

250 miles is equivalent to 400 kilometers.

We have,

To find out how many kilometers are equivalent to 250 miles, we can set up a proportion using the given information that 5 miles are equal to 8 kilometers.

5 miles : 8 kilometers

We can set up the proportion:

5 miles / 8 kilometers = 250 miles / x kilometers

To solve for x (the number of kilometers in 250 miles), we can cross-multiply and then divide:

5 miles x (x kilometers) = 8 kilometers x 250 miles

5x = 2000

Dividing both sides by 5:

x = 400

Therefore,

250 miles is equivalent to 400 kilometers.

a horse's heart beats 440 times in 10 minutes. A cow's heart bears 390 times in 6 minutes. which animal has a greater heart rate?

Answers

Answer:

The cow has a greater heart rate than the horse.

Step-by-step explanation:

The question demand we calculate the heart beat of each animal in relation to time . The number of heart beat per unit time can be computed as follows .

The horse heart rate is 440 heart beat in 10 minutes . The heart rate can be simplified as

Rate = 440/10

Rate = 44 heart beat per minute

The cow heart rate can be simplified as

Rate = 390/6

Rate = 65 heart beat per minute

From the Heart rate calculated above the cow has a higher heart rate than the horse.

390 ÷ 6 = 65

440 ÷ 10 = 44

The cow has a greater heart rate.

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.

Answers

Answer:

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

Stephanie ! I see that you tried to draw a picture, but you didn't get very far.

Can I tell you what this example wants you to practice ?
Three things:

Thing #1: Remember the formula for the area of a rectangle.

   Area = (length) times (width) .

Thing #2: Changing mixed numbers to fractions, and
   fractions to mixed numbers.

Thing #3: Multiplying fractions.

This sandbox is a rectangle.
Its length is 3-1/12 yards.
Its width is 2-3/4 yards.
What is its area ?

   Area = (length) times (width) .

    Area = (3-1/12 yards) x (2-3/4 yards) .

In order to multiply mixed numbers, you have to change them both to fractions.

-- Change 3-1/12 to a fraction

   3 and 1/12 is 3 wholes and 1/12
   Each whole is 12 / 12.
   3 wholes = 36/12
   plus one more = 37/12 .

-- Change 2 and 3/4 to a fraction.
   2 and 3/4 is 2 wholes and 3/4
   Each whole is 4/4 .
   2 wholes are 8/4 .
   plus three more = 11/4 .

There you are. Now you know the length and width
of the rectangle as fractions.

   Length = 37/12
   Width = 11/4

   Area = (length) times (width)

   Area = (37/12) times (11/4)

Do you remember how to multiply two fractions ?

==> Multiply the numerators to get the numerator.
==> Multiply the denominators to get the denominator.

   (37/12)   x   (11/4)

   = (37 x 11) / (12 x 4)

   =    (407) / (48)

That's it ! As an improper fraction, the area is

   407/48 square yards.

Now ... do you remember how to change an improper fraction
to a mixed number ?

I won't tell you how. Please look back in your math book, or in
the handouts, or in the homework, or in the notes, and find
how to change an improper fraction to a mixed number.
I know it's been taught in your class ... otherwise you would
not get this problem where you have to use it.

   407/48 =    (8 and 23/48) square yards.

That's the answer, but DON'T stop there. The answer is
NOT important. The important thing is that YOU need to
understand HOW to FIND the answer. Once you understand
that, it doesn't matter if you have the answer or not.
Nobody needs to know the area of Selena's sandbox !
