Step-by-step explanation:
we first divide fourteen by four
14/4= 3.5
then we change 0.5 to hours by multiplying by 60
0.5 * 60 = 30
so in conclusion it would take 3hrs 30mins to finish each activity
Answer: 2/3 feet per minute
Step-by-step explanation:
From the question, we are informed that a caterpillar moves across the grass at a rate of 4 2/3 feet every 7 minutes.
The rate at which the caterpillar move in feet per minute will be:
= 4 2/3 ÷ 7
= 14/3 ÷ 7
= 14/3 × 1/7
= 14/21
= 2/3 feet per minute

1099.99x 0.58 =637.9942
1099.99-637.9942= 461.9958
461.9958x 0.065=30.029727
461.9958-30.029727=431.967073
The answer round is 431.96
3.
42.95x1/5= 8.59
42.95-8.59 = 34.56
34.56 x 0.07=2.4192
34.56-2.4192= 32.1408
Round it is 32.14

1250x0.85= 1062.5
1250-1062.5 =187.5
(v-4t)(v+nt)
=v^2+vnt-4tv-4nt^2
