<u>Answer:</u>

W (-1, 4) ---> W' (-4, -1)

X (-1, 2)  ---> X' (-2, -1)

Y (2, 2)  ---> Y' (-2, 2)

Z (2, 4)  ---> Z' (-4, 2)

<u>Step-by-step explanation:</u>

We are given the graph with a rectangular figure WXYZ and we are to find the coordinates of its vertices W'X'Y'Z' after the transformation of 90° rotation.

We know that, the rule for 90° rotation of a point (x, y) gives (-y, x).

So,

W (-1, 4) ---> W' (-4, -1)

X (-1, 2)  ---> X' (-2, -1)

Y (2, 2)  ---> Y' (-2, 2)

Z (2, 4)  ---> Z' (-4, 2)

At a restaurant, three salads, two sandwiches, and one drink cost $17.75. One salad, one sandwich, and three drinks cost $10.75.
Leno4ka [110]

Answer:

A salad costs $2.50

A sandwich costs $4.50

A drink costs $1.25

Step-by-step explanation:

Let x represent the salad, y represent the sandwich, and z represent the drink.

Since three salads, two sandwiches, and one drink cost $17.75:

3x + 2y + z = 17.75  (1)

Since one salad, one sandwich, and three drinks cost $10.75:

x + y + 3z = 10.75  (2)

Since a salad costs twice as much as a drink:

x = 2z  (3)

Multiply the equation 2 by -2 then, sum the equation 1 and equation 2:

-2x - 2y - 6z = -21.50

3x + 2y + z = 17.75

→ x - 5z = -3.75

Replace the x with 2z using equation 3:

2z - 5z = -3.75

-3z = -3.75

z = 1.25

x = 2z → x = 2.50

x + y + 3z = 10.75 → 2.50 + y + 3.75 = 10.75 → y + 6.25 = 10.75 → y = 4.50

For 7/8 x 2/3 = the answer in simplest form, so we do the repricoral?
stiks02 [169]
Hello, so a simple way to do it is to cross cancel and then you would end up with 7/4 x 1/3 and it would equal 7/12 and that’s in simplest form.

What is the surface area of the solid that this net can form? A net has 2 rectangles. One rectangle has a base of 25 millimeters
JulijaS [17]

Answer:

S.A = 730mm²

Step-by-step explanation:

Since the solid is made up of two rectangles. Then the surface area (S.A) would be

S.A = area of first rectangle + area of second rectangle

Since the first rectangle has it's base to be 25mm and height to be 21mm, then it's area is

25mm x 21mm = 525mm²

Since the second rectangle has it's base to be 41mm and height to be 5mm, then it's area is

41mm x 5mm = 205mm²

Therefore

S.A = 525mm² + 205mm² = 730mm²
