Answer:
Raspuns corect: b)
Step-by-step explanation:
a4b=24, a×4×b=24⇒a×b=6
perechile de numere cu produsul 6 sunt: {1,6} si {2,3}
a4b in baza 10=100a+40+b
100×1+40+6=146
100×6+40+1=641
100 ×2+40+3=243
100×3+40+2=342
146+641+243+342=1372
Raspuns corect: b)
Hello!
We don't need to find the exact perimeter of the fencing, just an estimate.
We will round 12 ft 3 in to 12 ft, because it is closer to 12 ft than 13 ft.
We will also round 8 ft 11 in to 9 ft because there are 12 inches in a foot, which makes 9 ft closer.
The formula for perimeter of a rectangle is:
P = 2l × 2w
The length is about 12 feet and the width is about 9 feet.
Substitute the length and width:
P = 2(12) + 2(9)
Solve:
P = 24 + 18
P = 42
Jose will need about 42 feet of fencing.
Answer:

Answer:
16 mph
Step-by-step explanation:
Givens:
4 hours total time
48 miles total distance
So our equation should look like this.
48 = 2x(2) + x(2)
Where x = speed second half of trip.
x = 8
x*2 = 16 mph
