2 tenths is equal to____ fifths

2 answers:

5 0

To solve this, it is easiest to set up a proportion, letting x represent the number that we don't know.

2/10 = x/5

Now, we can use cross products to simplify this proportion. Cross products sets the products of the numerator and denominator of separate fractions equal to one another. It results in the equation:

(5)(2) = (10)(x)

Let's multiply out these numbers to further simplify the equation.

10 = 10x

Finally, we have to divide both sides by 10, to get our variable x alone

x = 1

Therefore, 2 tenths is equal to 1 fifth.

Answer: 120, 60, 180

Step-by-step explanation:

1) Area of a rectangle's formula is:

l × w

So, looking at the diagram, we get:

6 × 20 = 120 cm²

2) Area of a trapezoid's formula is:

$\frac{a+b}{2}$ × h (where both a and b are the different base lengths)

So, looking at the diagram, we get:

$\frac{10+20}{2}$ × 4 = 60 cm²

3) Add both to find the area of the entire figure.

120 + 60 = 180 cm²

Which of the following comparisons is FALSE?

dybincka [34]

Answer:

Step-by-step explanation:

Let's check each one-by-one.

we know 3.79 liters is 1 gallon, so 4 liters IS NOT LESS THAN 1 gallon

THis is false.

We know 1 feet is 0.30 meters, so definitely 1 foot is less than 1 meter.

This is true.

we know around 28.35 grams is 1 ounce, so definitely 25 grams is less than 1 ounce.

THis is true.

We know 1 km is approximately 0.62 miles so 10 km would be around 0.62*10 = 6.2 miles

So definitely 9 miles IS GREATER than 10 km.

THis is true.

So answer choice A is false, only.
