Answer:
D.) 28.26x²
Step-by-step explanation:
Diameter (d) = 6x
radius (r) = d/ 2 = 6x / 2 = 3x
area of circle
= π r²
= 3.14 * (3x) ²
= 28.26x²
Answer:
y=
Step-by-step explanation:
There are three letters A, B, C in order to make the tags and y is the number of tags that can be made using n spaces. So, there are three choices for the first letter A and three choices for the remaining two letters that are B and C respectively.
By the basic counting principle,
Formulae for the number of tags they can make using n spaces is: 3×3×3×3×..........×3( n times)
=
Therefore, y=
Answer:
x - y = 25
Step-by-step explanation:
3x - 4y = 15
-2x + 3y = 10
Add the two equations together
3x - 4y = 15
-2x + 3y = 10
----------------------
x - y = 25
Add all the beads together and put it over the number of blue beads.
so since there are 150 beads, the denominator is 150. and the amount of blue beads is 50 so that's the numerator.
50/150 now simplify, divide the numerator and denominator by 50 that equals
1/3
so the probability of getting a blue bead is 1/3

By definition, the volume of a rectangular prism is given by:
V1 = (w) * (l) * (h)
Where,
w: width
l: long
h: height
Substituting we have:
60 = (w) * (l) * (h)
if the length and the width double, and the height remains the same, we have:
V2 = (2w) * (2l) * (h)
Rewriting:
V2 = 4 * ((w) * (l) * (h))
V2 = 4 * V1
Substituting we have:
V2 = 4 * (60)
V2 = 240 cubic feet
Answer:
the new volume will be:
V2 = 240 cubic feet
