2.75 x + 3.55 y ≤ 2,479
x + y = 820
( x - number of units produced during the regular hours, y - number of units produced in overtime )
y = 820 - x
2.75 x + 3.55 · ( 820 - x ) ≤ 2.749
2.75 x + 2,911 - 3.55 x ≤ 2,749
- 0.8 x ≤ 2,749 - 2,911
- 0.8 x ≤ - 432 / · ( - 1 )
x ≥ 432 : 0.8
x ≥ 540
Answer:
The smallest number of units that must be assembled during the regular hours is 540.
We look for pairs of numbers in order to further simplify certain unsimplified square roots. For example, the square root of 20. From this, we pull out a 5 and two 2’s, Since there is a pair of 2’s, we carry one out, and since the 5 is not a pair, it stays inside of the radical. Therefore making it 2√5.
Answer:
0.75 sec
Step-by-step explanation:
we have the equation
------> equation A
------> equation B
Using a graphing tool
The solution of the system is the intersection point of both graphs
the intersection point is (0.75,370)
that means-------> For t=0.75 sec , d=370 ft
see the attached figure
Answer: 9p - 1.5a
Step-by-step explanation:
Your maximum heart rate is about 220 minus your age. But it varies base on age category.
Target heart rate during moderate intensity activities is about 50-70% of maximum heart rate.
According to the question;
Target heart rate for
women = 1/2p(418-4a)
= 209p - 2a ....... (1)
men = 1/2p(400-a)
= 200p - 0.5a .......(2)
To find the difference between the target heart rates for a fit woman and a fit man, take equation 1 from equation 2
(209p - 2a) - (200p - 0.5a)
209p - 2a - 200p + 0.5a
9p -1.5a
