I'm not sure how to explain it
If Taryn mowed 9 lawns in 7.5 hours and earned $112.50, then her hourly rate is:
$112.50 / 7.5 hrs = $15 per hour
If Alistair mowed 7 lawns in 5 hrs and earned $122.50, then her hourly rate is:
$122.50 / 5 hrs = $24.50 per hour
To earn an additional $735 each, they should work the following hours.
Taryn: $735 / $15 = 49 hours
Alistain: $735 / $24.50 = 30 hours
ANSWER
EXPLANATION
A) From the diagram, we see that the base of the triangular face is 4 cm long and the height of the triangular face is 3 cm.
B) From the diagram, we see that the length of two of the rectangular face is 15 cm and the width of the rectangular face is 5 cm.
The third rectangular face has a length of 15 cm and a width of 4 cm.
C) The surface area of the prism is the sum of the areas of the faces of the prism.
The area of a triangle is given as:
where b = base, h = height
The area of a rectangle is given as:
where l = length, w = width
Therefore, the surface area of the prism is:
