Answer:
x
Step-by-step explanation:
(log to the base 3) of 27^x can be re-written as
x*(log to the base 3) of 27, which is equivalent to:
x*(log to the base 3 of 3^3) = x
So the answer is simply " x "
Answer:
28 out of 40
2(20 - x)/40 for x questions wrong
Step-by-step explanation:
total points: 40
total Qs: 20
20-6 = 14
14/20 = 28/40
28
In the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.
<h3>What is the triangle?</h3>
The triangle can be defined as a three-sided polygon in geometry, and it consists of three vertices and three edges. The sum of all the angles inside the triangle is 180°.
In the first diagram:
The sum of the 5k + 20 and 7k + 40 is 180
5k + 20 + 7k + 40 = 180
12k + 60 = 180
12k = 180 -60
12k = 120
k = 10
In the second diagram:
The sum of the two interior angles is equal to the exterior angle.
40 + 12k + 10 = 8k + 80
4k = 30
k = 30/4 = 15/2
Thus, in the first diagram the value of k is 10 and in the second diagram the value of k is 15/2.

Answer:
The correct answer is option B. 8,16, 20
Step-by-step explanation:
Its given that,ΔJKL ~ ΔPQR, with a scale factor of 3 : 4
The sides of ΔJKL are, 6,12,15
Let 'x', 'y', and 'z' be the sides of ΔPQR
We know that if two triangles are similar, then the ratio of corresponding sides are in same raio.
<u>To find x</u>
6/x = 3/4
x = 8
<u>To find y</u>
12/y = 3/4
y = 16
<u>To find z</u>
15/z = 3/4
z = 20
Therefore the sides of ΔPQR are 8,16 and 20
Option B. 8,16,20 is the correct answer
