Suppose that Sahil knows that 45 people with the ages of 18 to 19 voted. With out using a calculator, he quickly says then 135 p
Amiraneli [1.4K]
So you are given that 45 people in the age range of 18 to 29 who voted make up 10% of the total voters.

And you also know that 30% of the voters are in the age range of 30-49. And you need to find out how many people aged 30-49 voted.

So 10% of the total make up 45 people.
That means for 30% of the total number people, there would be 45 x 3 people, or 135 people. Because 10% x 3 = 30%

So, great job! :D

Which of the following is the correct factorization of the polynomial below?<br> x3 + 14x2 + 49x
Naddika [18.5K]

For this case we must factor the following polynomial:

x ^ 3 + 14x ^ 2 + 49x\\

We can take common factor x:

x(x ^ 2+ 14x + 49)

To factor the expression within the parenthesis, we must find two numbers that when multiplied give 49 and when added together, 14 are obtained. These are: 7 and 7.

7*7=49,7+7=14

Thus, the expression is factored as:

x(x + 7)(x +7)

Answer:

x (x + 7) ^ 2

Your cell phone plan costs $44.99 per month. You also pay 20% in taxes and fees. What is your bill after taxes and fees?
katen-ka-za [31]
So the total bill will be 44.99 + 20% of 44.99 or the total bill (x) will equal 44.99 + .20 × 44.99

x = 44.99 + (.20)44.99
x = 44.99 + 9.00
x = $53.99

*note- .20(44.99) = 8.998 which rounds to $9.00
