40$ - 100% (full price)
x$ - 70% (100-30=70%)
40 * 70 = 100x
2800 = 100x
x = 28
Answer 28$
or
40$ = 100%
then 1% = 40/100 = 0.4$
so 70% will be 0.4 * 70 = 28$
Answer:
40.5 is what they are divided
Step-by-step explanation:
Since the y-intercept is -3, plot a point at -3 on the y-axis (vertical). Then, continue to make points by following the slope down.
Remember, slope is written as y/x
A slope of -1/2 could be interpreted as -1 over 2. So, each time you move down 1 space, you move to the right 2 spaces.
So, following the slope down, you'd plot another point at (2,-4). Then, another at (4,-5), and so on. Understand?
create a histogram with five intervals from this data set: 21, 37, 56, 87, 32, 45, 77, 71, 65, 67, 21, 34 step 1: find the minim

Answer:
Step-by-step explanation:
Step 1: Minimum= 21 Maximum= 87
Step 2: Range minimum= 20
Step 3: Range maximum= 90
Step 4: Range 90-20= 70
35. an open circle means there is no equal sign, and shading to the left means less then...so inequality is : x < 6
36. a closed circle means there is an equal sign, and shading to the left means less then.... x < = 9
in short...a closed circle means there is an equal sign, an open circle means there is not. if it is shaded to the left, it is less then...if it is shaded to the right, it means it is greater then.
37. x > 4
38. x > = 4
39. x < 1
40. x < = 5
41. x > = 5
42. x < 0
