13. five plus <em>y</em> equal to negative two. y = -7
14. eight plus <em>h</em> equal to twelve. h = 4
15. negative thirteen plus four equal <em>n</em>. n = -9
Answer:
15^3
Step-by-step explanation:
Since 15^4 means 15 x 15 x 15 x 15, therefore, just subtract the power 4 from one because you are dividing it by 15:
15^4 / 15 = 15^3
Answer:
Step-by-step explanation:
<em>A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10</em>
Complete Question:
Let x and y be positive integers and x be greater than y.
11x/11y = ?
Answer:
11x/11y = x/y
Step-by-step explanation:
Given
x > y
Required
11x/11y
From the question, we understand that x is greater than y (i.e. x > y)
Also, we'll assume that y ≠ 0, in other not to result in an undefined result.
So,
11x/11y
Divide the numerator and denominator by 11
(11x ÷ 11)/(11y ÷ 11)
The result of the division is:
(x)/(y)
x/y
Hence,
11x/11y = x/y for x > y and y ≠ 0
Answer:
The triangle C
Step-by-step explanation:
As we know:
The Law of Sines (or Sine Rule) is very useful for solving triangles:
where:
- a, b and c are sides.
- A, B and C are angles
Let analyse 3 answers:
a. Wrong, because we do not know the measure of each angle
b. Wrong, we do not the the lenght of side that is opposite the the angle 40°
c. True, we know the measure of the other missing angle is:
= 180° - 70°- 30°
= 80°
and we know one side is: 10m
Hence, using the Sine Law, we can find out the side of the other 2 sides of the triangles.
