If the question ask you to do gh(x), substitue the equation of h as the x in the equation g
Answer:
see explanation
Step-by-step explanation:
The perimeter of a rectangle = 2l + 2w ( l is length and w is width )
given w = 63, then
2l + (2 × 63) = 324
2l + 126 = 324 ( subtract 126 from both sides )
2l = 198 ( divide both sides by 2 )
l = 99 m ← length of garden
-----------------------------------------------------------------
The area of a rectangle = lw ( l is length and w is width )
given l = 94, then
94w = 5828 ( divide both sides by 94 )
w = 62 cm ← width of window
Actual area = (140-yd x 940-yd) = 131,600 square yards.
Estimated area = (100-yd x 850-yd) = 85,000 square yards
Error = (131,600 - 85,000) = 46,600 square yards
Error as a fraction of the actual area = 46,600 / 131,600 = 0.354...
To change a decimal to a percent,
move the decimal point 2 places that way ==> .
0.354... = 35.4.. % (rounded)
Jack should remove the maximum and minimum weight potatoes from the average weight of the potatoes to compensate for the extremes. Therefore, we are left with a data set of:
8, 9, 11, 7, 7, 8, 9, 7; so n = 8
The sum of these is 66
The average weight of each potato is:
66/8
= 8 ounces
Answer:
<em>12+16= 28m</em>
<em>28m</em> <em>is the combined height of the trees</em> .
Hope this helps !
