Answer:
6 miles
Step-by-step explanation:
3+1/2+2+1/2=6miles
16x^2 -1 = 0
16x^2 = 1
x^2 = 1/16
x= 1/4
Solve the problem yourself first, to see if Pedro made any mistakes.
4/7 x 8/5
4x8 = 32
7x5 = 35
32/35 is the answer.
Pedro made his error in step 2, he cross multiplied instead of multiplying the numerators, and then the denominators.
Answer:
142/1000 as a decimal equals 0.142
Explanation:
To write 142/1000 as a decimal you have to divide numerator by the denominator of the fraction.
We divide now 142 by 1000 what we write down as 142/1000 and we get 0.142.
Since you rolled 60 twos and 66 threes out of 360 times this experimental probability is (60+66)/360=126/360=0,35 which is c)
