Answer:
Question 2. 12% of 650 = 78
Step-by-step explanation:
100% = 1 in decimal form.
This is because finding 100% of something is the same as multiplying it by 1:
E.g. 100% of 10=10, 10x1 = 10
Therefore to find a percentage of something, we simply need to multiply it by the decimal form of that percentage. For example, if we were finding 50% of 10 (half), 50% in decimal form is 0.5, 10x0.5 = 5
The percentage here is 12%, we can find the decimal form by dividing it by 100, 12/100 = 0.12
So, in order to find 12% of 650, we just need to multiply 650 by 0.12:
650x0.12 = 78
12% of 650 = 78
Hope this helped!
Answer:
y = -3x -1
Step-by-step explanation:
the slope is -3 and the y-intercept is -1
Answer:
The constant of proportionality is 1.89
Step-by-step explanation:
2 pounds = $3.78
1 pound = $3.78/2 = $1.89
Cost y is directly proportional to the pound of potato
y = 1.89x
The constant of proportionality is the cost of 1 pound of potato, and it is 1.89
Answer:
perpendicular
Step-by-step explanation:
When 2 lines intersect at any point, not just in the middle of each (that has nothing to do with it), and they meet to form right angles, the lines are perpendicular to one another and their slopes are opposite reciprocals.
