Answer:

a.) 12.96kg b.) $90

Step-by-step explanation:

increasing 12 by 8%, first find 8 percent of 12,

8/100 x 12, then add that to the original 8

so 8/100 x 12 = 0.96, so increasing 12kg by 0.96kg, we get 12.96 kg

increasing 75 dollars by 20%, or 1/5th, we find 1/5th of 75, then add it onto 75

1/5th of 75 is 15, so 75 + 15 = 90

Answer:

a) 12.96 kg

b) $90

Step-by-step explanation:

a)\ 12+\frac{12\times 8}{100} =12+0.96=12.96

b)\ 75+\frac{75\times 20}{100} =75+15=90

Answer:

-\left|7+3\right|

Step-by-step explanation:

Solve each expression and then compare the results

case 1) we have

15-\left|-5\right|\\ \\=15-(5)\\ \\=10

case 2) we have

\left|-4\right|+6\\ \\=(4)+6\\ \\=10

case 3) we have

-\left|7+3\right|\\ \\ =-(7+3)\\ \\=-10

case 4) we have

\left|-10\right|\\ \\ =-(10)\\ \\=10

What is the volume of a hollow ball whose other radius is 200m and inner radius of 100m? What is the mass if it is iron?
kati45 [8]

Solution :

Volume of ball = Volume of outer ball - Volume of inner ball

V = \dfrac{4\pi R^3}{3} - \dfrac{4 \pi r^3}{3}\\\\V = \dfrac{4\pi}{3}( R^3 - r^3 )\\\\V = \dfrac{4\pi}{3}( 200^3 - 100^3 )\\\\V = \dfrac{4\pi}{3}(2^3 - 1^3) \times 10^6\\\\V = 2.93 \times 10^7 \ m^3

Now, density of iron is, d = 7300 kg/m³.

So, mass of iron ball is :

m = d\times V\\\\m = 7300\times 2.93 \times 10^7 \ kg\\\\m =  2.14 \times 10^{11}\ kg

Hence, this is the required solution.
