Answer:
At The given rate, the area of floor that Jessica can wax is 33.3 m²
Step-by-step explanation:
Given as :
The area of floor waxed = 20 square meters
The time taken to waxed 20 square meters floor = hours
Let The area of floor waxed per hour = A m²
<u>Now, Applying unitary method</u>
∵ In hours, The area of floor waxed = 20 m²
∴ In 1 hour , The area of floor waxed = m²
I.e In 1 hour , The area of floor waxed = m²
Or, In 1 hour , The area of floor waxed = = 33.3 m²
Or, In 1 hour The area of floor waxed = A = 33.3 m²
Hence, At The given rate, the area of floor that Jessica can wax is 33.3 m² Answer
Answer:
Square root of 87.35 will be plotted between 9 and 10 as shown below.
Step-by-step explanation:
We are given that, 'The number line is numbered in tenths'
Also, the square root of 87.35 is given by,
That is, we have to plot the point 9.4 on the number line numbered in tenths.
As, 9.4 will lie between the points 9 and 10.
Thus, we get that square root of 87.35 will be plotted between 9 and 10 as shown below.
