Answer: First, Third and Fourth options are correct.
Step-by-step explanation:
As we know that Rational numbers are those numbers which can be positive integers, negative integers and can be written in the form of p/q i.e. in fractions.
So, it is true for positive integers
It is true for negative integers.
It is true for fractions.
Hence, First, Third and Fourth options are correct.
Answer:
Angle 1 = 70, Angle 2 = 90, Angle 3 = 70, Angle 4 = 70
Step-by-step explanation:
1. 90 -20 = 70
2. Diagonals are perpendicular and create right angles that equal 90
3 and 4. Diagonals bisect angles, angles on opposite sides are congruent
Answer:
.
Step-by-step explanation:
In quadrilateral QRST, Q(-1,0), R(5,0), S(3.5,-6), T(-2.5,-6).
In quadrilateral Q'R'S'T', Q'(-1,2), R'(1,2), S'(0.5,0), T'(-1.5,0).
Distance formula:
Using distance formula , we get
Now,
Therefore the scale factor is .
(3.14 hours) x (60 min/hr) x (60 sec/min) = <em>11,304 sec</em>
