18x+9xy (9x⋅2)+(9x⋅y <span>(9x⋅2)+(9x⋅y You multiply 9x times 2 and then 9x times y. Because a(b+c) = ab + ac</span>
Answer:
c. Rational
because → whole numbers are positive and Starts from 0 so not whole number
Integers can be negative and positive
Examples of numbers that are not integers are: -1.43, 1 3/4, 3.14, . 09, and 5,643.1.
Irrational number that cannot be written in p/q
but -2.4 written in p/q = -24/100
<h3>so c. Rational Number is correct</h3>
Well since there was 560 students the it was 560/560. now that 50 got selected the total portion would be 560/6
Answer: It is not possible that two triangles that are similar and not congruent in spherical geometry.
Step-by-step explanation:
For instance, taking a circle on the sphere whose diameter is equal to the diameter of the sphere and inside is an equilateral triangle, because the sphere is perfect, if we draw a circle (longitudinal or latitudinal lines) to form a circle encompassing an equally shaped triangle at different points of the sphere will definately yield equal size.
in other words, triangles formed in a sphere must be congruent and also similar meaning having the same shape and must definately have the same size.
Therefore, it is not possible for two triangles in a sphere that are similar but not congruent.
Two triangles in sphere that are similar must be congruent.
1. Over a period of 6 years (from 1980 to 1986) the house gained a value of 12000 dollars (109k-97k). 12000/6 gives you a rate of 2000 dollars per year. Because the initial price at t=0 is 97000, the function is 97000+2000t
