MissTica

There are 51,191 employees working in the second phase

The production floor has a total number of 73210 employees that work in 2 phases

22,019 employees work in phase one

The number of employees that work in phase one can be calculated as follows

= 73,210-22019

= 51,191

Hence 51,191 employees work in the second phase

Given that U is the centroid of triangle OPQ find PS.
o-na [289]

Answer:

PS=5.4

Step-by-step explanation:

The centroid divides each median in the ratio 2:1

If U is the centroid, then

3.6:x+0.8=2:1

We use ratio to obtain;

\frac{3.6}{x+0.8}=\frac{2}{1}

Cross multiply;

3.6=2(x+0.8)

Expand;

3.6=2x+1.6

Group similar terms;

3.6-1.6=2x

2=2x

x=1

PS=PU+US

PS=3.6+1+0.8

PS=3.6+1+0.8

PS=5.4

Jim drove 152 miles in 4 hours. if he can keep the same pace, how long will it take him to drive 760 miles?
alexandr402 [8]
First we need to find the rate which is the total amount driven divided by the total time.

152/4 = 38 miles per hour.

No we take the total driven miles given and divide it by the rate to find how long it would take!
760/38 = 20 hours!
Hope this helps :D

Suppose you took eight math tests this semester. If your average score on your first six tests was 84 and your average score on
iris [78.8K]

Answer: 92

Step-by-step explanation:

Formula : Sum of first n numbers = Average x n

Given: Average score on first 6 tests= 84

A score on all 8 tests = 86

Then, Sum of first 6 numbers = 84 x 6 = 504

Sum of first 8 numbers = 86 x 8 = 688

Sum of two last numbers = (Sum of first 8 numbers) - (Sum of first 6 numbers)

= 688-504

=184

Average of last two numbers = (Sum of two last numbers )÷2

= 184÷2

= 92

Hence,  the average of your last two test scores = 92.
