Answer:
let's see...
we have total possible outcomes.. = 90 ( from 1 to 90)
Desiree outcomes..= 5 ( 17,34,51,68,85)
and therefore.. the probability is 5/90 = 1/18.
here you go.. that should be correct I hope.
Answer:
369
Step-by-step explanation:
37 + 3 = 40
40 × 3 = 120
120 + 3 = 123
123 × 3 = 369
and so on
Answer:5,-3
Step-by-step explanation:
Answer:
m∠RPS = 38°.
Step-by-step explanation:
It is given that ray PT is the angle bisector of angle RPS. It means PT divides the angle RPS in two equal parts.
Now, it is clear that
Therefore, the measure of angle RPS is 38°.
(a) The sum of length and width is half the perimeter, so the breadth in terms of length (x) in cm will be
.. breadth = 34 -x
(b) Then the expression for the area (in cm^2) is
.. area = length*breadth
.. 253 = (x)(34 -x)
.. x^2 -34x +253 = 0 . . . . . subtract the right side, eliminate parentheses
.. (x -11)(x -23) = 0 . . . . . . . factor
.. x = 11 or 23
The dimensions of the rectangle are 11 cm by 23 cm.
