Answer:
15) f = 18
3f = 54
6f = 108
16) k = 69
Step-by-step explanation:
15)
3f + 6f + f = 180
10f= 180
f = 18
16)
42 + k + k = 180
42 + 2k = 180
2k = 138
k = 69
Answer:
i am not really, sure but i believe it could be this
Step-by-step explanation:
The total required amount CB should have been receiving for
the past 4 hours should be:
Required quantity = (75 mL / hr) * 4 hr
Required quantity = 300 mL
The actual quantity CB received however is only:
Actual quantity = (45 mL / hr) * 4 hr
Actual quantity = 180 mL
Therefore the deficit is:
Deficit quantity = 300 mL – 180 mL
Deficit quantity = 120 mL
Since in a 1 liter (1000 mL) bag there is 40 mEq of KCl,
therefore the needed extra mEq of KCl that CB has to receive now is:
Additional KCl = 120 mL * ( 40 mEq / 1000 mL)
<span>Additional KCl = 4.8 mEq </span>
Answer:
Step-by-step explanation:
Please refer to the attachement. I defined the height (H), width (W), and length (L) and set:
H = 4m and W = (1/3)L. The total cost of 640 Rs/m^2 is divided by the rate cost of Rs 5/m^2 to give 128 m^2 that was plastered. The total area of the walls must be 128 m^2, so then calculate the total wall area: The walls for the length are 2*LH and for the width are 2*WH. Substituting, we have a total of 8*L + (4/3)L = 128 m^2. Solve for L to obtain L = 12m. W is 1/3L, or 4m. The room is (W,L,H) 4, 12, and 4 meters. The floor is W*L, or 48m^2. At Rs 250/m^2, the rug will cost Rs 12000. Ouch.
