Answer:
Fraction=3/10
Decimal=0.3
Percent=30%
Step-by-step explanation:
First we have to add 12+16 so we can find how many marbles are left
12+16=38
Then, we subtract it from the total number of marbles.the outcome of this operation would be equivalent to the number of blue marbles
40-38=12
There are 12 blue marbles.
Now, the we have to use experimental probability if you are familiar with the term is that the number of outcomes(the blue marbles) must be over the total sample space(total marbles) in a fraction.
Probability=
12/40
Simplify
12/40
6/20
3/10
Probability
Fraction=3/10
Decimal=0.3
Percent=30%
Since, A 3-mi cab ride costs $7.30 and a 8-mi cab ride costs $15.30.
In the information given above, we can consider these as the coordinate points on the axes.
Let (c, d) be the coordinates , where 'c' represents the total cost and 'd' represents the distance traveled.
Cost is on the 'y' axis and distance is on the 'x' axis.
Now, let the first point on the coordinate axes be (3, 7.30) and the other point is given by (8, 15.30).
For the given points say 
and 
, equation of line is given by:
where m(slope) is given by 
.
The equation of line for the given points is:
So, c = 1.6d+2.5 is the required linear equation that models a relationship between cost c and distance d.
Answer:
180 degrees
(x,y) becomes (-x,-y)
270 degrees
(x,y) becomes (y,-x)
90 degrees
(x,y) becomes (-y,x)
Step-by-step explanation:
Here, we want to write a rule for each of the counterclockwise rotation
The rule are as follows;
180 degrees
(x,y) becomes (-x,-y)
270 degrees
(x,y) becomes (y,-x)
90 degrees
(x,y) becomes (-y,x)
Answer:
12 + 42 = 54
Step-by-step explanation:
12 = 10 and 2
42= 40 and 2
40 + 10 = 50
2+2 = 4
