14n - 32 = 22 what does n equal

N = 3 and 6/7, because if we add both sides by 32, then the equation will look like 14n = 54, and if we divide both sides by 14 (to isolate the variable), then 54 divided by 14 is 3 and 6/7. Hope if helps :D

A bag contains 40 marble 12 red and 16 yellow what is the probability that a blue is randomly seclected
lora16 [44]

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%

A 3-mi cab ride costs $7.30. A 8-mi cab ride costs $15.30. Find a linear equation that models a relationship between cost c and
ASHA 777 [7]

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 (x_1,y_1) and (x_2,y_2) , equation of line is given by:

(y-y_1)= m(x-x_1) where m(slope) is given by \frac{y_2-y_1}{x_2-x_1}.

The equation of line for the given points is:

(c-7.30) = (\frac{15.30-7.30}{8-3})(d-3)

(c-7.30) = 1.6(d-3)

c-7.30 = 1.6d-4.8

c-1.6d=2.5

So, c = 1.6d+2.5 is the required linear equation that models a relationship between cost c and distance d.

13. Write a rule for each counterclockwise rotation about the origin:
ryzh [129]

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)
