Answer:
13/30
Step-by-step:
First, you find the common denominator, which is 30. For the first fraction, multiply the bottom by five. Since you do that, you have to multiple the top by 5 as well, giving you 25/30. For the second problem, you multiple the top and bottom by six giving you 12/30. 25 minus 12 is 13 so you get 13/30.
Answer:
4^ (r-s)
Step-by-step explanation:
When the bases are the same, and we are dividing, we subtract the exponents
x^a ÷ x^b = x^ (a-b)
4^r ÷ 4^s = 4^ (r-s)
Answer:
the answer is 13
Step-by-step explanation:
Y is multiplied by 1/2, because if it is directly proportional to x & x is halved, y must be halved too
Answer:
d = 32.73°
Step-by-step explanation:
Angle 'd' is an exterior angle of the given polygon.
By the property of the exterior angles of a polygon, sum of exterior angles of a polygon is 360°.
And the measure of an exterior angle of a polygon =
Here 'n' = Number of sides of the polygon
From the picture attached,
Number of exterior angles of the regular polygon = 11
Therefore, measure of the exterior angle =
= 32.7272
≈ 32.73°
