Answer:
1
Step-by-step explanation:
Take 4 1/2 and turn it into just halves by multiplying 4•2 and then adding it to one. 9/2 then multiply that by 2 because you need the denominator to be 4 getting 18/4. Then subtract 11/4 you end up getting 9/4. So technically you have 2 pieces but if you want them both to be 11/4 you only have one
1.15/3 = 20 minutes worth = 0.383
60 minutes+20 minutes=80 minutes = 1.15+0.383=1.53
1.5/3 = 0.5 = 20 minutes
60 minutes+20 minutes=80 minutes =1.5+0.5=2
2-1.53=0.47 therefore it is 0.47 minutes quicker with Model A

=======================================================
Work Shown:
See below for the diagram.
(person height)/(person shadow) = (tree height)/(tree shadow)
x/3 = 6/4.5
x*4.5 = 3*6
4.5x = 18
x = 18/4.5 ...... dividing both sides by 4.5
x = 4

Answer:
125+680w≥2,500+450w
Step-by-step explanation:
From the information given, you can say that the money that is received as donation should be equal or higher to the money necessary to cover the annual expenses, which would be the following inequality:
125+680w≥2,500+450w
Then, you can solve for w:
680w-450w≥2,500-125
230w≥2,375
w≥2,375/230
w≥10.33
