Answer:
1400
Step-by-step explanation:
67 rounds to 70 because 7 is bigger than 5 so it rounds up. 23 rounds down since 3 is smaller than 5.
So, 70x20=1400
As was the case in your previous question, this problem involves setting two ratios equal to each other. We call such an equation a proportion.
16 miles = x miles
(1/2) inch 2 3/4 inches
x = (11/4) * 16 = (11/4) * 2 * 16 = 88 miles
(1/2)
Answer:
39/18 = 13/6 = 2 1/6
Step-by-step explanation:
factors are 1,2,3,6,9,18
so the reciprocals are
1/1, 1/2, 1/3, 1/6, 1/9, 1/18
when added the sum is 39/18 or 2 1/6
Answer:
0 < x < 8
Step-by-step explanation:
| x-4| < 4
There are two solutions one positive and one negative. Remember to flip the inequality on the negative solution
x-4 <4 and x-4 > -4
Add 4 to each side
x -4+4 <4+4 and x-4+4 > -4+4
x < 8 and x > 0
0 < x < 8
open circles at 0 and 8 and a line connecting them
Answer:
(Wind speed: 81,000) and (Rate of the jet in still air: 11,820)
Step-by-step explanation:
We know that 5040 times 8 is 40320.
And 6780 times 6 is 40680.
Then, add them together and the rate of the wind is 81,000.
The rate of the jet, add them (6780 plus 5040) and you'' get 11,580.
