Given- 90% of runner completed the marathon.
out of which 30% are man.
To proof - let the total number of runner be y.
the men completed the marathon be 30% of the 90%.
thus we have
30% of 90% of y = 270
×
×y = 270
now solving the above equation
we get
Thus solving the equation
y = 1000
Thus the total runners of men who completed marathon be 1000.
Hence proved
Answer:
21.99 or just round to 22
Step-by-step explanation:
Radius is 3.5
Diameter is 7
Circumference is 21.99
96-15.2 = 80.8 pounds total used
80.8/10 = 8.08 pds used each day
Answer:
x = 6 2/3 The supplementary pair of angle is 78 degree and z = 112degree = 180 degree First step is where we can also see z its opposite angle is vertical opposite angle to 112 degree given and label as vertical angle - where we see a line through the 180 degree line at any angle we can call the pair supplementary- Pairs OR sets of angles an only be called consecutive when they are grouped with a set of parallel line across a straight line and it is only because they add up to 180 they could be either terms so as there isn't parallel shown ; <u>we know we an call a pair of angles upon a straight line supplementary.angles. </u>
Step-by-step explanation:
6 x +38 (+112) = 180 degree as angles on a straight line add up to 180 6 x +38 (+112) = 180 6 x +140 = 180 6 x + 140- 140 = 180-140 6 x = 40 x = 40/6 x = 6.66666667 x = 6 2/3 <u> </u><u>Proof (6( 6 2/3)) + 38 + 112 = 180</u> = (40+38)+112 = 180 = 78 +112 = 180 Proves the supplementary angle is 78 degree.
Answer:
is the last one
