Aiden estimates the length is 7.2 but it’s 6.5 what’s the percent error

IrinaVladis [17]

Percent error is 10.7%

Step-by-step explanation:

We need to find the percent error:

We are given:

Estimate value = 7.2

Actual value = 6.5

Percent Error=?

The formula used is:

$Percent\,\,Error=\frac{Estimate\,\,value-Actual\,\,value}{Actual\,\,value}\times100\\$

Putting values:

$Percent\,\,Error=\frac{7.2-6.5}{6.5}\times100\\Percent\,\,Error=\frac{0.7}{6.5}\times100\\Percent\,\,Error=0.107\times100\\Percent\,\,Error=10.7%\\$

So, Percent error is 10.7%

Two sides of an acute triangle measure 5 inches and 8 inches. The length of the longest side is unknown.

nordsb [41]

The greatest whole possible whole number length of the unknown side is 9 inches

Solution:

Two sides of an acute triangle measure 5 inches and 8 inches

The length of the longest side is unknown

We have to find the length of unknown side

The longest side of any triangle is a hypotenuse

For a acute triangle we know:

If c is the longest side of a acute triangle, a and b are other two sides of a acute triangle then the condition that relates these three sides are given as:

$c^2$

Here in this sum,

a = 5 inches

b = 8 inches

c = ?

Substituting we get,

$c^2< 5^2+8^2\\\\c^2 < 25 + 64\\\\c^2 < 89\\\\c < 9.4$

On rounding to nearest whole number,

c < 9

Hence, to the greatest whole possible whole number length of the unknown side is 9 inches

I believe that would be the last choice, because it is not impossible that someone without contacts or glasses would be chosen. And it is a fairly similar chance that someone with glasses or with contacts will be chosen. Hope this helps! :)

Please help is the perimeter rational or irrational

ASHA 777 [7]

To find the area you multiply l x w so, to find the sides you do the opposite, sq root of 24,200 (we can use the square root because we know it is a square and all sides are equal)=155.563492. This is only the length of one side. 155.563492*4=622.253968 which is a rational number.
The perimeter is a rational number.
