Answer:
<h3>2T/9</h3>
Step-by-step explanation:
A construction manager needs 12 workers to complete a building project in 54 days, we can write;
12 workers = 54 days
T find the number of workers needed to complete the same project in T days, we will write;
x workers = T days
Divide both equations
12/x = 54/T
Cross multiply
12T = 54x
x = 12T/54
x = 2T/9
Hence the number of workers needed to complete the same project in T days is 2T/9 workers
<span>A 15° sector in a circle has an area of 11.9 m2. What is the area of the circle?
The area of the circle will be found as follows:
the fraction of the sector=15/360=1/24
the area of the circle will be:
area=(fraction of the circle)/(fraction of the sector)*(area of the sector)
=1/(1/24)</span>×11.9
=285.6 m²

Answer:
= 2,937/2
OR
= 1468.5
Step-by-step explanation:
Given that:
= ( 96 x 16 ) + 14 - ( 163 / 2 )
Solving the brackets first
= 1536 + 14 - 163/2
Taking LCM to make denominators same:
= 1536*2/2 + 14*2/2 - 163/2
= (3,072 + 28 - 163) / 2
By simplifying we get:
= 2,937/2
OR
= 1468.5
i hope it will help you!
