Answer:
McDonald’s Quarter Pounders = 67 mg of cholesterol
Burger King Whoppers = 87 of cholesterol
Step-by-step explanation:
McDonald’s Quarter Pounders = m
Burger King Whoppers = b
2m + 3b = 395
3m + 1b = 288
3m + b = 288
b = -3m + 288
2m + 3b = 395
2m + 3(-3m + 288) = 395
2m - 9m + 864 = 395
- 7m + 864 = 395
- 7m/7 = -469/7
-m = -67
-m/-1 = -67/-1
m = 67
2m + 3b = 395
2(67) + 3b = 395
134 + 3b = 395
3b = 395 - 134
3b = 261
3b/3 = 261/3
b = 87
Check: m = 67; b = 87
2m + 3b = 395
3m + 1b = 288
2m + 3b = 395
2(67) + 3(87) = 395
134 + 261 = 395
395 = 395
3m + 1b = 288
3(67) + 1(87) = 288
201 + 87 = 288
288 = 288
(Probs too late but welp :p)
Divide the current year by the previous year then multiply it by 100.
Volume of a cone, V = πr^2h/3
r = Sqrt 3V/πh = Sqrt [(58.9*3)/(3.14*9)] = 2.5 cm, minimum
Surface area, A = πr [r+ Sqrt (h^2+r^2)] = 3.14*2.5*[2.5+ Sqrt (9^2+2.5^2)] = 92.95 cm^2
Therefore, minimum amount of paper required is 92.95 cm^2
Answer: 1)100ways and 2)90ways
Step-by-step explanation:
Given :-The 10 students who completed a special flying course are waiting to see if they will be awarded the one Distinction or the one Merit award for their efforts.
Ways can the two awards be given if the same student can receive both awards (i.e repetition is allowed)
=10×10=100ways
Ways can the two awards be given if the same student cannot receive both awards(i.e. repetition is not allowed)
=10×9=90ways
