Answer:

18 students are good in maths and their percentage is 72%

Step-by-step explanation:

The number of people who are not good in maths is 28% × 25 which is

(28/100)× 25

(28/4)×1

So 7 people are not good in maths.

To find those who are good in maths, subtract this number from the total.

25 -7=18

The percentage is =(18/25) ×100

= 18×4

= 72%

Answer:

$\large\boxed{3.\ \dfrac{1}{625t^{12}}}$

Step-by-step explanation:

$\text{Use}\\\\(ab)^n=a^nb^n\\\\(a^n)^m=a^{nm}\\\\a^{-n}=\dfrac{1}{a^n}\\---------------\\\\(5t^3)^{-4}=\dfrac{1}{(5t^3)^4}=\dfrac{1}{5^4(t^3)^4}=\dfrac{1}{625t^{(3)(4)}}=\dfrac{1}{625t^{12}}$

melisa1 [442]

Answer:3.14

Step-by-step explanation:

Volume of cylinder can be calculated by using the formula V= pir^2h

Where r is radius of cylinder and h is the height.

A cylinder with radius 1 inch and height of 1 inch is given.

r=1,h=1,π=3.14.

Substituting the given values :

V=3.14(1)^2(1)

Volume of cylinder rounded to nearest tenth is 3.14 cubic inches .
