Answer:
K = 3
Step-by-step explanation:
4.5 + 1.5 k = 18 - 3k
Put terms on one side
1.5k + 3k = 18 - 4.5
4.5k = 13.5
k = 3
Answer:
C.) 33.60
Step-by-step explanation:
OMP. = $56
D. = 25%
0.25 * $56 = $14
SP. = $56-$14=$42
CD. = 20% of Selling price
= 0.20 * $42 = $8.40
FSP. = $42-$8.40 = $33.60
The dotted lines indicate that this object is a sphere, so we will use the formula for finding the volume of a sphere to solve this problem.
Volume of a sphere: 4/3r³
The figure shows us that the radius of the sphere is 2.8 cm, so we will plug in 2.8 for r in the formula.
4/32.8³ = 91.95
The volume of the figure is 91.95 cm³.
Answer: 20
Step-by-step explanation:
Given : The orchestra at millard middle school has 120 members.
Of these 17% are eighth grade students.
i.e. Percentage of eighth grade students in orchestra = 17%
Then, the number of eighth grade students in the orchestra. = (Percentage of eighth grade students in orchestra) x ( Total members in orchestra)
= 17% x 120
[We convert % into decimal by dividing it by 100]
[Round to the nearest integer.]
Hence, the estimated number of eighth grade students in the orchestra is 20.
