steposvetlana [31]

Answer:

Area of the self will be =4\times \frac{2}{3}=\frac{8}{3}=2.666ft^2

So length pf the shelf l = \frac{2}{3} feet

And width = 4 feet

We have to find the area of the self

Area = length × width

So area of the self will be =4\times \frac{2}{3}=\frac{8}{3}=2.666ft^2

Question : 3/4+ 0.6 = ? 1.15 1.35 1.45 or 1.05
Artyom0805 [142]

we have

\frac{3}{4} +0.6

we know that

\frac{3}{4}=0.75

and

0.75=0.40+0.35

substitute in the expression

0.40+0.35 +0.6

(0.40+0.60)+0.35

(1.00)+0.35=1.35

therefore

<u>the answer is</u>

1.35
