4/5* x= 2/5
⇒ x= 2/5/ (4/5)
⇒ x= 2/5* (5/4)
⇒ x= 1/2

[box] equals 1/2 (i think; check by dividing 0.8 by 0.4 on calculator, or 4/5 divided by 2/5 on fraction calculator... kind of obvious)

The width of a large, rectangle-shaped tree farm is 1.9 kilometers. The best length of the farm is 4.4 kilometers. What is the b
brilliants [131]
To make estimates, we usually round the numbers the nearest integer.
Since 1.9 is closest to 2 than it is to 1, the nearest integer of 1.9 is 2.
Similarly, since 4.4 is closest to 4 than it is to 5, the nearest integer of 4.4 is 4.

Now, to estimate the area of the farm, we are going to multiply our two integers:
Estimated Area of the Farm= 2x4=8

Since 8 is between 4 and 10, we can conclude that the best estimate of the area of the farm is: between 4 and 10

A snail crawled 7 miles in 8.4 hours. At this speed, how long would it take the snail to crawl 10 miles?
Angelina_Jolie [31]

Answer:

12 hours

Step-by-step explanation:

Let's set the speed as "s".

Remember that distance = speed * time

So, plugging the numbers given...

7 = s * 8.4

Divide both sides by 8.4

s = 5/6

Now, plug this into the distance = speed * time, with the distance being 10. Set the time as "t"

10 = 5/6 * t

Divide both sides by 5/6

12 = t

So, it would take 12 hours for the snail to crawl 10 miles.

The second side of a triangular deck is 3 feet longer than the shortest side and a third side that is 3 feet shorter than twice
abruzzese [7]

The perimeter of a triangle is:

P = a + b + c

 

We are given that:

b = a + 3

c = 2 a – 3

 

Therefore:

68 = a + a + 3 + 2 a – 3

68 = 4 a

a = 17

 

and,

b = a + 3 = 20

<span>c = 2a – 3 = 31</span>

Now consider the product of a nonzero rational number and an irrational number. Again, assume x = , where a and b are integers a
vovangra [49]

Answer:

Irrational number

Step-by-step explanation:

It's given,

y = \frac{mb}{na} (By simplifying the product of rational number 'x' and an irrational number 'y')

Where m and n are the integers and \frac{b}{a} is a rational number.

(Since x = \frac{a}{b} is a rational number)

Therefore, \frac{mb}{na} will be a rational number.

y = \frac{mb}{na} ⇒ Irrational number = Rational number

which is a contradictory statement.

Therefore, multiplication of rational and irrational number will be irrational.
