What is the probability of rolling an even number or a perfect square using a 20-sided die?
Gemiola [76]

Answer:

C) 12/20

Step-by-step explanation:

Between 1 and 20, 10 numbers are even, 4 numbers are perfect squares (1, 4, 9, and 16), and 2 numbers are both even and perfect squares (4 and 16).

So the probability is:

(10 + 4 − 2) / 20 = 12/20.

Brian was asked to write x72 as a product of 2 powers with the same base in 4 different ways, using only positive exponents.
Oksana_A [137]

The equivalent expression to the value given using the laws of indices is  {x}^{4(18)}

Evaluating the options given based on the laws of indices :

  • {x}^{8}. {x}^{9}  =  {x}^{8 + 9}  =  {x}^{17}
  • {x}^{35}. {x}^{47}  =  {x}^{35 + 47}  =  {x}^{82}
  • {x}^{4(18)}  =  {x}^{4 \times 18}  =  {x}^{72}
  • {x}^{24}. {x}^{3}  =  {x}^{24 + 3}  =  {x}^{27}

Therefore, the only expression which would give a correct way of representing {x}^{72} \: is \: {x}^{4(18)}

A clerk is marking up merchandise 34%. The original price of an item is $455. What will be the retail price?
Galina-37 [17]
Take the orginal price and multiply it by 1.34.
455 * 1.34 = $609.70 in retail.

The longer way would be to take 34% of 455 and then add it to 455.
