Answer:
x=4
Step-by-step explanation:
4x - 3 = 2x + 5
4x - 2x = 5 + 3
2x = 8
x = 8/2
x = 4
Round 1 player 1 because 12 is the greatest number
Answer:
Which cone has a volume of 24 7 cm?
-
1
-
-
3.5 cm!
4.5 cm
1
6.5 cm
B = 25.4 cm
1
7/5 cmi
1
8 cm
3 cm
B = 42
Step-by-step explanation:
Volume=height times area of base
base=circle so area of base=pir^2
ok so solume=height times pi times r^2
1.
thermos, h=10, r=2
therefor
volume=10pi2^2=
volume=10pi4=
40pi in^3 is brought to school
2. inside is 4 inches deep
h=4, r=1.5
volume=4pi1.5^2
volume=4pi2.25
volume=9pi
answer is 9pi in^3
3. so find 80% of 9pi
80%=0.8
0.8 times 9pi=7.2pi in^3
each times is 7.2pi in^3
4. ok so this is assuming that you fill the mug to 80% (7.2pi) each time and the remainder is it less or more or equal to half of 7.2pi so
total in thermos=40pi
each pour=7.2pi
40pi-7.2pi-7.2pi-7.2pi-7.2pi-7.2pi=4pi
is 4pi more or less than 7.2pi
7.2pi/2=3.6pi
4pi>3.6pi
it is MORE
1. 40pi in^3
2. 9pi in^3
3. 7.2pi in^3
4. MORE than half
Answer:
Step-by-step explanation:
Given the original coordinate as C (-6, 9) and new coordinates after dilation as C' (-2, 3), we can see that the value of the new coordinates has reduces by a factor. Let the factor be k
For the x coordinates:
C' = kC
x' = kx
-2 = k(-6)
-2 = -6k
Divide both sides by -6
k = -2/-6
k = 1/3
For the y-coordinates:
y' = ky
3 = 9k
Divide both sides by 9:
3/9 = 9k/9
1/3 = k
k = 1/3
Hence the scale factor of the dilation is 1/3
