Answer:
Follows are the description of the given point:
Step-by-step explanation:
Please find the correct question in the attached file.
In point A:
An order of 5 items shall be placed in a total of 6 different ways.
(w for cars and ts and tricycles to be used)

In point B:
2 waggons so more tyres would be required if they ordered any more waggons.

15 / 21 = 75 / x.....15 shots to 21 grams = 75 shots to x grams
cross multiply
(15)(x) = (75)(21)
15x = 1575
x = 1575 / 15
x = 105 grams <===
The maximum point will be the point which gives the largest f(x,y) value. The "y" is subtracted and being multiplied by 2 so very small y-value, large x is point (5,0).
Answer:
The surface area of the given pyramid is 112
.
Step-by-step explanation:
Base length of the pyramid = 4 inches
Area of the base = 
= 
= 16
Area of its base = 16 
Area of one of its triangular surface =
x base x height
=
x 4 x 12
= 2 x 12
= 24 
Area of all its four triangular surfaces = 4 x 24
= 96 
surface area of the pyramid = sum of areas of all its surfaces
= 16 + 96
= 112 
The surface area of the given pyramid is 112
.
welll...you have there written just one relationship...it is berween 280 and 4 hours...you have to figure out speed:

it is speed per hour
then you just connect time and speed:
- 140 - 2
- 280 - 4
- 350 - 5
- 420 - 6
- 560 - 8
- 700 - 10
