Amanda brought 6 t-shirts that cost the same amount each and 2 jackets that cost $55 for each jacket. The total cost of items Am

anda brought was $350 before the tax was added. What is the cost of each t-shirt?

so lets take the cost of 1 T-shirt to be x

Since Amanda bought 6 t-shirts we can say the cost of 6 T- shirts is 6x

So the total cost of items = 55*2 +6x

(55 \times 2) \:  + 6x = 350 \\ 110 + 6x = 350 \\ 6x = 350 - 110 = 240 \\ 6x = 240 \\ x =   \frac{240}{6}  \\  x =40

Ans: Each T-shirt is $40

A, b, and c are collinear, and B is between a and c. The ratio of AB to AC is 1:2. If A is at (7,-1) and B is at (2,1) what are
Nutka1998 [239]

Answer:

C(-3,3)

Step-by-step explanation:

Given

A = (7,-1)

B = (2,1)

AB:AC = 1:2

Required

Determine the coordinates of C

Since, B is between A and C; we need to determine ratio BC as follows;

AB:AC = 1:2

Convert to division

\frac{AB}{AC} = \frac{1}{2}

<em>AC = AB + BC;</em>

\frac{AB}{AB + BC} = \frac{1}{2}

Cross Multiply

2 * AB = 1 * (AB + BC)

2 AB = AB + BC

2AB - AB = BC

AB = BC

Divide both sides by BC

\frac{AB}{BC} = 1

Rewrite as

\frac{AB}{BC} = \frac{1}{1}

Write as ratio

AB:BC = 1:1

Next is to determine the coordinates of C as follows;

Because B is between both points. we have:

B(x,y) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Where

m:n = AB:BC = 1:1

B(x,y) = B(2,1)

A(x_1,y_1) = A(7,-1)

So; we're solving for x2 and y2

B(2,1) = (\frac{mx_2 + nx_1}{m+n},\frac{my_2 + ny_1}{m+n})

Where

Solving for x2;

x = \frac{mx_2 + nx_1}{m+n}

2 = \frac{1 * x_2 + 1 * 7}{1+1}

2 = \frac{x_2 +  7}{2}

Cross Multiply

2 * 2 = x_2 + 7

4 = x_2 + 7

x_2 = 4 - 7

x_2 = -3

Solving for y2;

y = \frac{my_2 + ny_1}{m+n}

1 = \frac{1 * y_2 + 1 * -1}{1+1}

1 = \frac{y_2- 1}{2}

Cross Multiply

2 * 1 = y_2 - 1

2  = y_2 - 1

y_2  = 2 + 1

y_2  = 3

<em>Hence, the coordinates of C are: C(-3,3)</em>

Kipish [7]

To get the probability of two individual events both occurring, you have to multiply the probabilities of their individual events occurring. Therefore in this problem, the probability that a student selected at random will pass both French 101 and French 102 is 0.683 (.75 x .91). The answer is already rounded to three decimal places.
