I am 100% sure that A equals -2.3
Answer:
The surface area of right prism is 12 feet² , option D
Step-by-step explanation:
Given as :
The measure of base = 4 ft
The height of base = 0.5 ft
The surface area of right prism = perimeter of base × height + 2 × base
Now ,
Perimeter of base = 4 + 4 = 8 ft
So, The surface area of right prism = 8 × 0.5 + 2 × 4
Or, The surface area of right prism = 4 + 8
∴ , The surface area of right prism = 12 feet²
Hence The surface area of right prism is 12 feet² . Answer
Answer:
luxury=15
sports cars 25
Step-by-step explanation:
Step one:
let the luxury cars be x
and the sports cars be y
the objective function is
maximize
15000x+16000y=625000------1
the constraints are
1. Man-hours
1600x+1500y=61500-----------2
Step two:
the system of equation for the situation is
15000x+16000y=625000------1
1600x+1500y=61500-----------2
let us reduce both equation
divide equation 1 be 1000
and equation 2 by 100 we have
15x+16y=625--------1 x15
16x+15y=615--------2 x16
225x+240y=9375
-256x+240y=9840
=-31x+0=-465
31x=465
x=465/31
x=15
put x=15 in 15x+16y=625 we have
15(15)+16y=625
225+16y=625
16y=625-225
16y=400
y=400/16
y=25
2.5 - 0.25x = - 3
0.25x = 2.5 + 3
x = 5.5 / 0.25
x = 22
In short, Your Answer would be: Option D
Hope this helps!
Answer:
a. (-3,3), (18,-6), (9,15)
Step-by-step explanation:
If the scale factor is 3 and dilation is about the origin, each of the coordinates of the pre-image is multiplied by 3 to get the coordinates of the image.
Multiplying (-1, 1) by 3 gives (-3, 3), which matches choices A and C.
Multiplying (6, -2) by 3 gives (18, -6) which matches choices A and D.
The only viable choice is choice A.
