An inequality that represent the number of cans, c, that Jacob must still collect is
.
<u>Step-by-step explanation:</u>
Here we have , Jacob needs to collect at least 120 cans for a food drive to earn community service credit. He has already collected 64 items. We need to solve the following :
<u>Part A:
</u>
Write and solve an inequality to represent the number of cans, c, that Jacob must still collect.
Jacob has collected 64 cans . Jacob need to collect at least 120 cans for a food drive to earn community service credit , Let Number of cans that Jacob have to collect is c , So following is the inequality for above scenario:
⇒ 
⇒ 
⇒ 
Therefore , An inequality that represent the number of cans, c, that Jacob must still collect is
.
It would be 4x < h < 10x
the difference between 3x - 7x =4
and the sum would be 3x + 7x =10
It means that when both sides of an equation have the same number subtracted from them the remaining expressions are equal. ( ......Hope that I helped you...... )
360 degrees in a circle
32/360 of total area is sector area
area=pir^2
r=8.5
area=pi8.5^2
area=226.980022 mm^2
multiply it by 32/360
sector=20.17600195555556
round
sector=20.2
C is answer
