12x2= $24
24+28+45= $97
So $97 is 100%
So 100%-30% =70% (30% off)
(note: 70% = 70/100 = 0.7)
97 x 0.7 = $67.90
Answer:
(-3,6)
Step-by-step explanation:
As graph shows x=-3 and y=6
Answer:
the one worth more is 4.1 billion
Answer:
117.99
Step-by-step explanation:
First step is to find the discount
Discount = original price * discount rate
= 135 * 20%
= 135*.20
=27
Take the discount from the original price and that is the new price
new price = original price - discount
= 135-27
=108
Now we need to find the tax
tax = new price * tax rate
= 108 * 9.25%
= 108 * .0925
=9.99
The final price is the new price plus the tax
final price = new price + tax
= 108+9.99
=117.99
Answer:
Option D is not a rational number
Step-by-step explanation:
A rational number is one that can be represented in the form of fraction like X/Y, where X and Y are integers and X ≠ 0. While an irrational number is one that cannot be expressed in the form of simple fractions.
For example, ¾ is a rational number while √3 is an irrational number.
Now to the question;
A) The product of 2 and 0.3333 gives;
2 × 0.3333 = 0.6666.
This can be expressed as a fraction as; 6666/10000.
Thus it is a rational number
B) The sum of 2 + √3 and 5 - √3 gives;
2 + √3 + 5 - √3 = 7
As a fraction, it can be written as; 7/1
Thus it is a rational number.
C) The sum of 37 and 12 is;
37 + 12 = 49
Can be expressed as; 49/1
Thus,it's a rational number.
D) Product of 2 and √2 gives;
2 × √2 = 2√2
It can't be expressed as a fraction with integers. Thus, it's not a rational number.
