Answer:
He needs 3.75 lbs of sugar and 1.25 lbs of water.
Step-by-step explanation:
Let x lbs be the amount of sugar in the syrup. Then 5-x lbs is the amount of water in this syrup.
Note
5 lbs - 100%
x lbs - 75%
Write a proportion:
Cross multiply:
So, he needs 3.75 lbs of sugar and 5 - 3.75 = 1.25 lbs of water.
The ratio of the area of the sector (S) to the area of the entire circle (C) is equal to the ratio of the angle subtended to form the sector (As) to the angle for the whole revolution (Ac)
S / C = As / Ac
Substituting the given,
S / 36 m² = 40 degrees / 360 degrees
Solving for S gives, S = 4. Thus, the area of the sector is 4 m².
Answer:
Its A and B
A.K.A
a.k.a The inequality is equivalent to -20.2 > 0, which is false. and The solution is 0 > y.
The choices you provided do not match the question!!!
Tickets ($25): x
T-shirts ($12): y
25x + 12y + 4 ≤ 130
Since she bought 3 tickets: 25(3) + 12y + 4 ≤ 130
75 + 12y + 4 ≤ 130
79 + 12y ≤ 130
12y ≤ 51
y ≤ 
y ≤ 4
Since you cant buy of a T-shirt, the maximum number of T-shirts she can purchase is 4.
Direct variation equal is written as : y = kx
K is the constant of variation.
12 = k4
12/4 = k
k = 3
y = 3x
Answer: <span>B. y = 3x </span>
