Solve: 12 dogs decreased by 25% step by step pls.

first turn 25% into a decimal so it's easier to work with, the decimal for 25% is 0.25

then multiply the number by the decimal

12x0.25=3

then subtract your answer (3) from your starting number

12-3=9

12 dogs decreased by 25% leaves you with 9 dogs left.

if you are increasing, divide instead of multiply

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.

hope i .

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.
