Find the cost of one bar first
$6.23 divide by 7 = $0.89
$0.89 x 5 =$4.45
Answer:
The image of the point is (-27, 6)
Step-by-step explanation:
<em>Let us talk about the dilation</em>
- Dilation is a transformation that changes the size of a figure. It can become larger or smaller, but the shape of the figure does not change.
- The scale factor of dilation measures how much larger or smaller the image will be. If the scale factor greater than 1, then the image will be larger. If the scale factor between 0 and 1, then the image will be smaller
- If the point (x, y) is dilated by scale factor k and the center of dilation is the origin, then its image will be (kx, ky)
∵ Point (-9, 2) is dilated by a scale factor 3
∴ k = 3
∵ The center of dilation is the origin
→ Multiply the coordinates of the point by 3 to find the image
∴ The image = (3 × -9, 3 × 2)
∴ The image = (-27, 6)
The image of the point is (-27, 6)
Answer:
m∠OPQ + (2x+16)° = 180°
Step-by-step explanation:
You need to know a couple of things about quadrilaterals.
- The sum of the internal angles is 360°
- Opposite angles of an inscribed quadrilateral total 180°.
An inscribed quadrilateral is one that has its vertices on a circle, as in the given figure.

To actually solve the figure (find the measures of the angles), a two-step process is involved. First, you must find the value of x. You do that by making use of the fact that angles O and Q total 180°.
After you know the value of x, you can figure the measure of angle R, and make use of the fact that angles R and P total 180°.
__
Here, you're not asked to solve the figure. Instead, you're asked how you might find angle P. You do that as described in the previous paragraph:
m∠OPQ + m∠ORQ = 180° . . . . . . . angles R and P total 180°
m∠OPQ + (2x+16)° = 180° . . . . . . . substitute (2x+16)° for m∠ORQ
This matches the first answer choice.
I think c would be the correct answer
