ANSWER:
4242.64 lbs*ft
STEP-BY-STEP EXPLANATION:
To better understand we make a sketch of the situation:
Where,
Distance ||PQ|| = 100 ft
Force (F) = 60 lbs
The angle between force and displacement is 45°
Component of force along displacement is F * Cos 45°
The total work is calculated by means of the formula shown in the statement:
The total work is equal to 4242.64 lbs*ft
Answer:
11 11/18
Step-by-step explanation:
Let the no. of $10 bills be x, the no. of $5 bills be 2x, and the no. of $20 bills be y.
<span>A cashier collects 124 bills => x + 2x + y = 124 => 3x +y =124
</span>totaling $920 dollars => ($10)(x) + ($5)(2x) + ($20)(y) = $920 => 20x + 20y = 920
Now you got 2 equations :
3x +y =124 &
20x + 20y = 920
3x +y =124 => y=124-3x
Then Sub y=124-3x into 20x + 20y = 920,
ie. 20x + 20(124-3x) = 920
20x + 2480 - 60x = 920
2480 - 40x = 920
2480 - 920 = 40x
1560 = 40x
x = 39
Answer:
3-3x=-4x-3
