So an easier way to look at this is to think of the decimals as percentages, to convert these decimals to percentages we can multiply each by 100.
Which gives us 58% of students with fruit, and 36% students with crackers. We know that 58% is much larger than 36%, so more students bring fruit instead of crackers.
<span>Let A be the center of a circle and two angles at the adjacent center AOB and BOC. Knowing the measure of the angle AOB = 120 and the measure BOC = 150, find the measures of the angles of the ABC triangle.
</span>solution
Given the above information;
AC=AB, therefore ABC is an isosceles triangle.
therefore, BAO=ABO=(180-120)/2=30
OAC=OCA=(180-90)/2=45
OBC=BCO=(180-150)/2=15
THUS;
BAC=BAO+OAC=45+30=75
ABC=OBA+CBO=15+30=45
ACB=ACO+BCO=15+45=60
Let u=x^3
the original equation becomes: u^2-9u+8=0
factor this quadratic equation: (u-8)(u-1)=0
u=8, or u=1
that means x^3=8 or x^3=1
x=2 x=1
Answer:
<em>x+y=4</em>
Step-by-step explanation:
hello :
note : by identity you have x²-y² = (x-y)(x+y)
in this exercice : 2x²-2y² = 2(x²-y²) = 2 (x-y)(x+y)
means : 2 (x-y)(x+y) = 40
but x-y = 5
so : 2(5)(x+y) =40
x+y=40/10
<em>x+y=4</em>
Answer:
B.8 ft by 3 ft.
Step-by-step explanation:
The dimensions of the pyramid, expressed in ancient Egyptian units of measurement, were 280 cubits high, a base length of 440 cubits, with a seked of 512 palms (a slope of 51°50'40").
