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%

Evaluate the following expressions given x=6 and y=-3

Nana76 [90]

$\purple{5 \times 6 - 4 \times ( - 3)}$

$= 30 + 12$

$\blue{ = \boxed{42}}$

$\purple{ {6}^{2} + \frac{6}{ - 3} }$

$= 36 - 2$

$\blue{ = \boxed{34}}$

$\purple{(6 - 5 {)}^{3} + {( - 3)}^{2} }$

$= {1}^{3} + 9$

$= 1 + 9$

$\blue{ = \boxed{10}}$

Hope it helps

Jane has a checkbook balance of $68.00. She then writes two checks, one for $5.00 and one for $62.50. She also deposits $75.00.

That would be D. The first two would be fight (I think) except they don't include turning the calculator on. C is just plain wrong. D has all the right keystrokes.
