Answer: $7 change remains
Step-by-step explanation: When doing rounding in word problems, in most situations you will have to round up regardless of numbers. Rounding to the nickel then means that the cents on the cash amounts must be .00 or .05 Following this pattern:
0.87 is rounded to 0.90
2.66 is rounded to 2.70
3.90 is rounded to 3.90
1.63 is rounded to 1.65
2.53 is rounded to 2.55
1.30 is rounded to 1.30
Then just add together the rounded amounts, which is $13
Simply subtract with the formula, 20-13=7

Step-by-step explanation:

=> 6^2+[-77+5]
=> 6^2+(-72)
=> 36+(-72) [6^2 = 36]
=> -36

Hello-
6² + (y - x) is our equation. And wonder of wonders, our x and y values are given! What a beautiful thing, having both given to us.
x = -5
y = -77
Let's plug our given values into our equation for x and y. Like so-
6² + (y - x) becomes 6² + (-77 - (-5))
In math, we must do whatever operations are contained within parentheses first and foremost. So we must subtract -5 from -77. That, by the way, equals -72.
6² + -72
Now we do our exponents, or powers.
6² = 36
36 + -72
Now we do the easiest part - adding.
32 + -72 = -36
So the answer to this problem (if I've done my algebra correctly) is -36.
Hope this helps.

Step-by-step explanation:
3s = 8s - 5s
8s = 8s
s = 0, 1, 2, 3.......
so infinite solutions
D)
Step-by-step explanation:Given equation:
[tex]3s = 8s - 5s[/tex]To simplify this equation, we need to isolate the variables on one side of the equation and the constants on the other side of the equation. To do this, we can simplify the R.H.S as like terms can subtract.
⇒ [tex]3s = 8s - 5s[/tex]
⇒ [tex]3s = s(8 - 5)[/tex]
⇒ [tex]3s = s(3) = 3s[/tex]
⇒ [tex]3s= 3s[/tex]
Since both sides of the equation are the same, this system of equations has infinite solutions.
Check:We can check our answer by substituting the value of "s" into the equation. As a result, you will see that many values of "s" are satisfying the equation. Thus, Option D is correct.

Answer:
The missing leg measures b = 4 millimeters in length.
Step-by-step explanation:
The Pythagorean theorem should be used to find the missing leg measure.
The formula is a2+b2=c2, where a and b are the leg lengths and c is the hypotenuse length. This is known as the Pythagorean theorem.
Let's use the Pythagorean theorem now that a = 3 and c = 5.
a^2 + b^2 = c^2 - This is the Pythagorean theorem equation.
3^2 + b^2 = 5^2 - Fill in the equation with a=3 and c=5.
9 + b^2 = 25
b^2 = 16 - Take 9 off both sides or subtract.
square root of b^2 = square root of 16 - Take the square root of both sides of the equation.
b = 4 - Simplify
The missing leg measures b = 4 millimeters in length.

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Line t is tangent to the circle.
Hence, We know that;
The angle formed by a chord and a tangent is equal to 1/2 the measure of the intercepted arc.
Thus, The value of measure of arc DEF is,
