1 hour each day is used for test
so 8-1=7 used per day
so commercial is 1 in the 4:2:1 so
4+2+1=7
ok, so 7 units, 7 hours
4 hour for private
2 hour for research
1 hour of commerical
4*5=20=private
2*15=30=research
1*4=40=commercial
20+30+40=90
percent from commercial
40/90=0.44444444444≈44.44% about 44%
Answer: the angles do not have the same reference angle.
Step-by-step explanation:
Number of sides= 10
Side length= 4.6 ( or in this case base)
161 sq inches / 10 = 16.1 area of triangle.
Area of triangle =(b<span>ase * </span>height)/2
16.1=(4.6*h)/2
multiply 16.1 by 2 (cancels the dividing the 2)
32.2=4.6*h
divid 32.2 by 4.6
<span>7 is the height of the triangle</span>
Answer:
Where's the graph?
Step-by-step explanation:
12x2-7=6-2x2+2
14x^2-15=0
a=14 , b =0 , c=-15
0^2-4x14x(-15) =
840
