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=

x

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
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 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>
Answer:
Irrational number
Step-by-step explanation:
It's given,
y =
(By simplifying the product of rational number 'x' and an irrational number 'y')
Where m and n are the integers and
is a rational number.
(Since x =
is a rational number)
Therefore,
will be a rational number.
y =
⇒ Irrational number = Rational number
which is a contradictory statement.
Therefore, multiplication of rational and irrational number will be irrational.
Answer: $108
Step-by-step explanation:
80 x .35 = 28
80+28= 108
