Step-by-step explanation:
Lcm (72; 75) = 1,800: least common multiple, calculated. The numbers have common prime factors.
Step-by-step explanation:
the area of a triangle is baseline×height/2.
the baseline is here 5.8 cm
and the height is given : 2.4 cm
so, the area is
5.8 × 2.4 / 2 = 5.8 × 1.2 = 6.96 cm²
Answer:
42 Dimes, 10 Nickels.
Step-by-step explanation:
Dimes are worth $0.10, nickels are worth $0.05.
If D = number of dimes, and N = number of nickels, then the following equations are true:
0.10D + 0.05N = 4.70
D + N = 52
Next, let's multiply the first equation by 10 so that we can subtract the second one from it.
D + 0.50N = 47
(-) D + N = 52
Subtracting the second equation from the first one gives:
-0.5N = -5
-0.5N/-0.5 = -5/-0.5
N = 10
Finally, substitute N in the original second equation to find D.
D + 10 = 52
D + 10 - 10 = 52 - 10
D = 42
C: 60 children because 60 cannont go into 9 which is the amount of children in the first ratio
