<span>How many square feet will be required for 15 children?
</span>
<span>Will a space 22 ft. by 24 ft. meet the requirement?
</span>
<span>Yes</span>
0.9
3.32/1.66+18.4 is 20.4
3.32 rounds down to 3
1.66 rounds up to 2
18.4 rounds down to 18
3/2+18 is 19.5
Since they want a positive difference the bigger number goes first
20.4-19.5=0.9
time= distance/speed
take distance as d. take time as t.
the time taken: d/ 65 for the train however it is the same distance for d/130 so we can say (d/65)-3 = d/130
now solve the equation, multiply both sides by 130
2d-390=d
2d-d=390
so d=390 mi
Answer:
45
Step-by-step explanation:
Since the values are relatively small substitute i = 1 to 5 into 3i and sum
(3 × 1) + (3 × 2) + (3 × 3) + (3 × 4) + (3 × 5)
= 3 + 6 + 9 + 12 + 15
= 45
