Gabby assumed she could sell 45 boxes of cookies by Friday, but she only sold 26 boxes. What was Gabby's percent error?

Agata [3.3K]

Answer:

73.07%

Step-by-step explanation:

Given that,

Actual value of sold cookies = 26

Assumed value of sold cookies = 45

We need to find Gabby's percent error. The percentage error in a value is given by :

Error = ](Assumed value - Actual value)/Actual value]× 100

So,

$\%=\dfrac{45-26}{26}\times 100\\\\=73.07\%$

So, Gabby's percent error is equal to 73.07%.

144=(x+7)^2 take the square root of both sides...

12=x+7 subtract 7 from both sides...

x=5

So the original was a 5m square.

255=WL and you are told that W=L+2 so the equation becomes:

255=(L+2)L

255=L^2+2L

L^2+2L-255=0

L^2+17L-15L-255=0

L(L+17)-15(L+17)=0

(L-15)(L+17)=0 Since L>0...

L=15yd, and since W=L+2, W=17yd so

length=15, width=17yd
