The number of even positive integers less than a.b, i.e 90, is 45.
<h3>What are Arithmetic operations?</h3>
Arithmetic operations can also be specified by subtract, divide, and multiplying built-in functions.
Given that
a = 7 and b = 13
⇒ ab
Substitute the values of a and b in the above expression,
⇒ (7)(13)
⇒ 91
Since the number of even positive integers is less than
⇒ ab > even positive
⇒ 90 > even positive
since the even number less than a.b i.e. 91 is 90,
Here, 90 is the 45th number in the series of even positive numbers.
Thus, the number of even positive integer less than a.b, i.e 90, is 45

Answer:
B. 3x² +2 = 0
Step-by-step explanation:
The equation of A has a couple of real roots. We're pretty sure there are complex numbers that will satisfy this equation, but we don't know how to find them. (We suspect a typo, and that the equation is supposed to be 2x² +1 = 7x, which has only real roots.)
__
The equation of B can be rewritten as ...
x² = -2/3
This will have complex roots.
__
The discriminants of both equations C and D are positive, so those have only real roots.
2x² -5x -1 ⇒ d = (-5)² -4(2)(-1) = 33
3x² -6x -1 ⇒ d = (-6)² -4(3)(-1) = 48
For every 3 tablespoons of cocoa, Nate uses 1 tablespoon of sugar.
Since the sugar is halved, the cocoa should be halved as well. 6/2 is 3.
Then x+y=52....................(1)
<span>and 2x + 4y= 148..........................(2) </span>
<span>multiplying equation (1) by 2 </span>
<span>we get </span>
<span>2x +2y = 104............................(3) </span>
<span>subtracting equation(3) from equation (2) </span>
<span>2y=44 </span>
<span>y=22 </span>
<span>that is x=52-22=30 </span>
<span>there are 30 emus and 22 wombats</span>
