Answer:
$0.75
Step-by-step explanation:
Greg spends $0.45 on a eraser and $0.30 on a pen. How much money does Greg spend?
Well first you find the key words, (How much) which means you will be using addition in this problem. The numbers you will be adding are $0.75 and $0.30 which equals, $0.75
Answer:
0.77 M
Step-by-step explanation:
I'm going to assume this is a half-circle
Formula:
A = (πr^2)/ 2
D = 1.4
r = 0.7
A = (π 0.7^2)/2
A = (0.49π)/2
A = 0.7693
A = 0.77
Answer:
Step-by-step explanation:
assuming it is 
Using Quadratic formular -
a - 1
b - 8
c - 4
Answer: x = 18
Step-by-step explanation:
First, since both angles shown are equal to each other, you can immediately set your equation.
5x + 5 = 95
Next, move 5 to the opposite side of the equation to isolate your x value (5x). This step is simply subtracting the hanging 5.
5x + 5 (-5) = 95 (-5)
5x = 90
Finally, you need to divide both sides of the equation by 5 (the 5 next to the x) to *fully* isolate the x value.
5x / 5 = 90 / 5
x = 18
final answer: x = 18
Hopefully this helps with the remainder of your lesson! :)
Step-by-step explanation:
In the expression a^n, for integer values of n greater than 1, there are n factors. For example, a^2 = a * 2 (2 factors), a^3 = a * a * a (3 factors), etc.
For a non-negative value of a, a^n is non-negative for all values of n.
If a is negative, and n is even, then a^n is non-negative.
If a is negative, and n is odd, then a^n is negative.
|a| is non-negative for all values of a.
sqrt_n(a^n) is negative for negative a and odd n, but |a| is always non-negative, so sqrtn(a^n) cannot equal |a| for odd n.
