Answer:
D. 12) 25.68 = 2.14
Step-by-step explanation:
Given :
Divisor = 1.2
Dividend = 2.568
We can make the divisor a whole number by multiplying the divisor by 10,
i.e. Divisor = 1.2 x 10 = 12
Similarly , dividend = 2.568 x 10 = 25.68
Therefore,
<u> 2.14 </u>
12 | 25.68
<u> (-) 24 </u>
16
<u> (-) 12 </u>
48
<u> (-) 48 </u>
0
Hence the answer is 2.14
V( cone ) = 21 cm³
note Vof cone = V of cylinder
V ( cone ) = × 63 = 21 cm³
Distribution method
(2x+6)(2x-6)
=4x^2-12x+12x-36
=4x^2-36
answer:
a = 15
b = 84
c = 81
steps
a+b+c=180
b=3a+39
c=a+66
a+3a+39+a+66=180
5a + 105 = 180
5a = 75
a = 15
b=3a+39
b=3(15)+39
b=45+39
b=84
c=15+66
c=81
