Answer:
Step-by-step explanation:
<u>Area formula:</u>
<u>The height is:</u>
- h = (x + 2)sin 45° = √2(x + 2)/2
<u>Substitute the area value an set an equation:</u>
- 4√2 = (2x - 3)√2(x + 2)/2
- (2x - 3)(x + 2) = 8
- 2x² + x - 6 = 8
- 2x² + x - 14 = 0
- D = 1 + 4*2*14 = 113
- x = (-1 + √113)/4 = 2.41 (rounded)
Note. the second root ignored as negative
Distance = speed * time
d = 40(2)
d = 80 miles
Answer:
The real perimeter is:

And the area would be:

Step-by-step explanation:
For this case we know one side of a square given 6mm.
We can begin calculating the perimeter for the scale figure with this formula:

The area for this case is given by:

And we know that the drawing has a scale of 1 mm : 7 km and if we convert the perimeter to km we got:

And the area would be:

42 is the LCD of all the above fractions.
Answer:
a). 3M = [ 6.5 1.3 23.4 ]
[ 8.6 28.6 11.7 ]
b). 2M = [ 10 20 36 ]
[ 24 44 18 ]
The number of each type of toy needed to be double the output.
