If the shirt is on sale for 15.12 all you have to do is multiply $15.12 x 3 which gives you $45.36 so now take $56.00 - $45.36 and it will give you $10.64 which is the answer so Blake saves 10.64 cents simple.

The coordinates of three of the vertices of parallelogram ABCD are A(1, 0), B(2, 3), C(3, 2). What are coordinates of the fourth

nalin [4]

Answer:

A) The coordinates of the fourth vertex are:

1) x-coordinate:

$x=2$

2) y-coordinate:

$y=-1$

B) The point of intersection of the diagonals is: $(2,1)$

Step-by-step explanation:

We need to remember that the diagonals of a parallelogram intersect each other at a half-way point and the midpoint of each diagonal is the same.

The midpoint formula is:

$M=(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Since:

$M_{AC}=M_{BD}$

We can find the coordinates of the fourth vertex $D(x,y)$ through these procedure:

1) x-coordinate:

$\frac{1+3}{2}=\frac{2+x}{2}\\\\2(2)=x\\\\4-2=x\\\\x=2$

2) y-coordinate:

$\frac{0+2}{2}=\frac{3+y}{2}\\\\1(2)-3=y\\\\y=-1$

Therefore, fourth vertex is $D(2,-1)$

Since the point of intersection of the diagonals is the midpoint of a diagonal (Remember that $M_{AC}=M_{BD}$ ), this is:

$M_{AC}=M_{BD}=(\frac{1+3}{2},\frac{0+2}{2})\\\\M_{AC}=M_{BD}=(2,1)$

Therefore, the point of intersection of the diagonals is $(2,1)$

2 1/4 - 2/3. A. 1 3/7. B. 1 7/12. C 2 3/7. D 2 11/12

DedPeter [7]

Answer:

B.) $1\frac{7}{12}$

Step-by-step explanation:

$2\frac{1}{4} -\frac{2}{3} Then multiply 4 by 2, then add 1.frac{9}{4} - \frac{2}{3} \\$

Then find the Least Common Denominator(LCD); simply just multiply 4 by 3 to get 12; then multiply using the opposite number.

$\frac{3}{3} *\frac{9}{4} - \frac{4}{4} * \frac{2}{3}$

to get: $\frac{27}{12} - \frac{8}{12}$ .

now the denominators is the same on both sides, just subtract the numerator.

27 - 8 = 19

Now simply: $\frac{19}{12} = 1\frac{7}{12}$ .

Your final answer is 1\frac{7}{12}[/tex].
