The answer to this word problem is letter A. 200.
Here is the solution:
given:
candy bars in batches of 800
fixed cost of $ 20 per batch
variable cost of $ 0.10 x
x= the number of batches
<u>$ 20 ( 800 )</u> = <u>16, 000</u>
$ 0.10 (800) 80
= 200
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.
On this exercise is given that a triangle with vertices A(-6,-3), B(7,-7), and C(0,3) was dilated by a scale factor of 1.5, and it is asked to find the vertices of the image of the triangle after the dilation occurred.
Pre-image Image
A(-6,-3) --- (-6*1.5,-3*1.5) --- A'(-9,-4.5)
B(7,-7) ---- (7*1.5,-7*1.5) ---- B'(10.5,-10.5)
C(0,3) ----- (0*1.5,3*1.5) ----- C'(0,4.5)
The coordinates of the triangle's image after a dilation with a scale factor of 1.5 are represented by the points A'(-9,-4.5), B'(10.5,-10.5), and C'(0,4.5).
Answer:
0.65
Step-by-step explanation:
0.6 is short for 0.60
0.7 is short for o.7
0.61,0.62,063,0.64,0.65,0.66,0.67,0.68,0.69,0.70
0.65 is in the middle
Answer:
a. 4x+7 b. 4(5y+1) c. 19z-9 d. 4
Step-by-step explanation:
I know they all are correct.
Answer:
k=21
Step-by-step explanation:
Find the slope of MN which is 1/5 (use the slope formula)
Use the slope formula for AB using k as y_2
Substitute and you get k=21
21-2.25/-2.25-1.5=-5
The lines are perpendicular because the slopes are the negative reciprocal of one another.
