We grapht hem
we see that the base is from (-2,2) and (6,2), 8 units long
the height will be from y=2 to y=8 or 6 units
so then, the area=1/2 times base times height=1/2 times 8 times 6=24 square units
-40/80 = -1/2
since when you’re multiplying fraction, you multiply the top by the top number and bottom by the bottom number. So -4 • 10 is -40 and 5 • 16 is 80. -40/80, simplified is -1/2.
Answer:
y = 2x
Step-by-step explanation:
Given y is directly proportional to x then the equation relating them is
y = kx ← k is the constant of proportion
To find k use the condition when x = 4, y = 8, that is
8 = 4k ( divide both sides by 4 )
2 = k, thus
y = 2x ← equation of proportion
Answer:
Step-by-step explanation:
radius r = 10/2 = 5 ft
height h = 5 ft
Volume = πr²h = π(5²)(5) = 125π ≈ 392.7 ft³
Answer: 45
Step-by-step explanation:
Total number of 8th graders that signed up = 30
9 dropped out. So the total number 8th graders on board the game
= 30 - 9 = 21
46 2/3 % of the club are 8th graders i.e 21
Let T be the total number of students in the club
46 2/3 % T = 21
(140/3)% T = 21
(140/300)T = 21
T = (21x300)/140 = 45
Therefore, there are 45 students on the club
