Answer:
They can finish the race in 15 x 14 x 13 x 12 x 11 = 360360 order.
Step-by-step explanation:
There are 15 bicyclists in the race. The first position would come from the first bicyclist to the 15th. Meaning the first position can be occupied by 15 individuals. The second position can only be occupied by 14 individuals since one person is already first. Same way the third, fourth and fifth positions can be occupied by 13, 12 and 11 individuals respectively.
Therefore, they can finish the race in
15 x 14 x 13 x 12 x 11 = 360360 order.
Answer:
<u>4.1 </u>
Step-by-step explanation:
0.4(-5)+6.1
0.4 times -5 is -2
-2 +6.1 = <u>4.1 </u>
Answer:
The measure of angle A = 133°
Step-by-step explanation:
The sum of opposite angles of cyclic quadrilateral is 180°
From the figure we can see that,quadrilateral ABCD is inscribed in a circle.
<A + <C = 180°
<u>To find the value of x</u>
we have,
(4x + 5) + (x + 15) = 180
4x + 5 + x + 15 = 180
5x + 20 = 180
5x = 180 - 20 = 160
x = 160/5 = 32
<u>To find the measure of angle </u>
m<A = 4x + 5
x = 32
m<A = 4*32 + 5 = 128 + 5 = 133°
Therefore the measure of angle A = 133°
