Answer:
<em><u>= </u></em><em><u>28.27m </u></em>
Step-by-step explanation:
<h3>
AREA OF CIRCLE <u>
= 2 π r</u></h3>
= 2 x 3.14 x 3m
<em><u>= 28.27m </u></em>
Answer:
try 67 and see if it was right
If the zeros are r1,r2, ..., rn and the leading coefficient is a
then
p(x)=a(x-r1)(x-r2)....(x-rn)
Answer:
It takes <u>8 4/7 </u>days for both bricklayers to build the wall together.
Step-by-step explanation:
The first bricklayer takes 15 days to build the wall, which means it builds 1/15 of the wall per day.
The second bricklayer takes 20 days to build the wall, which means it builds 1/20 of the wall per day.
So if they build the wall together, the expression below will tell how much of the wall they build per day together.
1/15 + 1/20
To add the fractions, we must find a common denominator, which is 60.
4/60 + 3/60, which equals 7/60.
So, they can build 7/60 of the wall per day together. How many days will it take them? We must find how many times 7 fits into 60, which can be done by solving 60/7, which is 8 4/7.
So, it takes 8 4/7 days for both bricklayers to build the wall together.
