What are the ordered pairs
Percent change formula:
C = x - x
2 1 / x
1
To calculate percent change we need to take the difference between the starting value and final value, divide by the absolute value of the starting value, and multiply the result by 100.
1. 72 is a 33.333% decrease of 108. Round is 33%.
2. 90 is a 20% increase of 75. Round is 20%.
3. 49 is a 75% increase of 28. Round is 80%.
(24y⁵/15x⁸)÷(8y²/4x⁴).
(8y⁵/5x⁸)÷(2y²/x⁴)=8y⁵/5x⁸×x⁴/2y²=4y³/5x⁴
Answer:
$5.61
Step-by-step explanation:
we know that
At a dinner, the meal cost $22 and a sales tax of $1.87 was added to the bill.
so
using a proportion
Find out how much would the sales tax be on a $66 meal
Let
x ----> the amount of sales tax on a $66 meal
Answer:
Obtaining the area or perimeter is the easiest and basic skills in geometry, however, when combining several plane figures, composite shapes are formed, which can include: squares, circles, triangles, rectangles, trapezoids, etc.
To obtain the area or perimeter of this type of figures should analyze the figure and follow these steps:
STEP I
♦ Must identify which figures form the total.
STEP II
♦ Analyze if there are parts of the figures that you will not need, for example the sides that join two or more figures.
STEP III
♦ Obtain separately the areas and perimeters of each figure
STEP IV
♦Add the obtained in each figure.
Hope it helps you!
