Answer:

Step-by-step explanation:
A diameter is two times longer than a radius. Therefore, if the diameter
d = 24in, then the radius r = (24in) : 2 = 12in.
The formula of an area of a circle:

Substitute:


Then

Answer:
y=-15x+50
Step-by-step explanation:
You originally had 50 dollars, so +50. Then, it decreases at a rate of 15 every week, so -15x.
Y is the total number of money she has.
y= -15x+50
Answer:
Step-by-step explanation:
x² -14x+50= 0
this equation has 2 solutions because is a quadratic
the solurions are imaginary roots because the discriminant is less then 0
b²-4ac = (-14)²-4*1*50 = 194-200= -6
to find the actual roots use the quadratic formula
The ratio of boys to girls is
12:24
(which is already one statement)
the ratio, simplified, is
1:2
(ratio are like fractions, which is how I was able to "simplify" it)
Answer:
From 4-5 the shape is rotated 180 degrees.
Step-by-step explanation:
If you are standing up and you jump to face the other way your turning 180 degrees. If you turn to your side that would be 90 degrees and for a full turn 360 degrees.
