Which of the following options have the same value as 30\%30% of 8181? choose 3 answers: choose 3 answers: (choice a) a \dfrac{30}{100}\cdot 81 100 30 ⋅81 (choice b) b 0.3\cdot 810.3⋅81 (choice c) c 0.03\cdot 810.03⋅81 (choice d) d \dfrac{3}{10}\cdot 81 10 3 ⋅81 (choice e) e 30\cdot 8130⋅81

Hence, choice B is true.

Step-by-step explanation:

We are asked to find which value is similar to the value of the expression:

30% of 81.

We know that 30% of 81 could also be represented mathematically as:

30%×81=

which could also be written as:

choice A:

=

Which is not similar to equation (1).

Hence choice A is not similar.

Choice B:

This expression is similar to equation (1).

Hence choice B is true.

Choice C:

Which is not similar to equation (1).

Hence, choice C is not true.

Choice D:

=

Which is not similar to equation (1).

Hence, choice D is not true.

Choice E:

Which is not similar to equation (1).

Hence, choice D is not true.

d. 145*2 is 290 than the total angle is 360 then minus 290 then divide by two
