Mary is painting pumpkins to earn money. She plans on selling each pumpkin for $7.50. She currently has $200 in her savings acco unt. Is the amount of money in her bank account proportional to the number of pumpkin she sells?
1 answer:
Answer: No. It's not proportional
Step-by-step explanation:
The direct proportion in mathematics is expressed as:
y = kx
where
y = $200
k = constant
x = $7.50
We then solve for k
y = kx
200 = 7.50k
k = 200/7.50
k = 26.67
Since k isn't a whole number, then the amount of money in her bank account proportional to the number of pumpkin she sells.

Answer:
5/4 (d)
Step-by-step explanation:
wed- 610
mon - 488
Ratio = Wed/mon = 610/488
(610/2)/(488/2) = 305/244
305 = 61 x 5
244 = 61 x 4
cancelling out the 61 on both number = 5/4
Y+7=1/2(x+2) y+7=1/2x+1 7=1/2x-y+1 7-1=1/2x-y 6=1/2x-y 1/2x-y=6 Hope this helps!! :)
This is the concept of application of the Pythagorean theorem. The resultant speed of the motorboat which is crossing the river that has a northward current of 5 m/s at a speed of 8 m/s will be given by: c^2=a^2+b^2 c^2=8^2+5^2 c^2=64+25 c^2=89 c=sqrt89 c=9.4 m/s
