Answer:
Step-by-step explanation:
The total amount Rita spent is ...
(18.54x +23) +(25) = 18.54x +48 . . . total spent
__
When x=2, that is approximately ...
(18.5)(2) + 48 = 37 +48 = (40 -3) +(50 -2) = (40 +50) -(3 +2) = 90 -5 = 85
Rita spent about $85 if she bought 2 items.
_____
<em>Additional comment</em>
Estimation is often done using 1 significant figure. In this case, that would mean rounding the equation to 20x+50, so it would give a value of 90 when x=2.
An additional task when estimating is to estimate the error in the estimate. Here, using 20x+50 has an error of approximately 1.5x+2 (too high), so the error for 2 items will be about (1.5(2)+2) = 5. That is, the estimate of 90 is approximately 5 too high. Even this estimate has a remaining small error of 0.04x (too low).
The center of a triangle must always be found inside the triangle given that it is concurrent point of the three median lines of the triangle all three of which are located only inside of the triangle
The examples of the properties of the center of a triangle are;
- The center of the triangle is the centroid of the triangle which is the point of concurrency of the three medians of the triangle, where a median line is the line which connects a vertex to the midpoint of the side opposite the vertex inside the triangle
- Each median line divides the area of the triangle in half, and given that the area of the triangle is equal to half the altitude, multiplied by the length of the base side of the triangle, the three medians of a triangle are related and share a common concurrent point <em>inside</em> the triangle such the perpendicular distance from the concurrent point of the three medians to each of the three side is less than the altitude of the triangle
Given that the three medians are located inside the triangle therefore, based on the location of the center of the triangle on the medians of the triangle, the center of the triangle must always be found inside the triangle

the amount of cereal in a box
the amount of milk in a milk carton
the amount of space inside a van
Answer:
10
Step-by-step explanation:
Begin with writing down your problem. For example, you want to divide 1284 by 14.
Decide on which of the numbers is the dividend, and which is the divisor. The dividend is the number that the operation is performed on - in this case, 1284. The divisor is the number that actually "does the work" - in this case, 14.
Perform the division - you can use any calculator you want. You will get a result that most probably is not an integer - in this example, 91.7142857.
Round this number down. In our example, you will get 92.
Multiply the number you obtained in the previous step by the divisor. In our case, 92 * 14 = 1294.
Subtract the number from the previous step from your dividend to get the remainder. 1284 - 1294 = 10.

<h2>ANSWER:-</h2>
We know that:-
Angle sum property if Triangles tells us that sum of angles of a triangle is equal to 180°.
So, First, we will find the third inner angle.


Now, let us find x.



So, 31° is the answer. (c)
