Answer:
Measure of angle 3 = 30⁰
Because vertically opposite angles are always equal
The result of the given exponential expression is given as 1/8, 3^2, 1/5 and 5^-2
<h3>Properties of exponents</h3>
Some of the properties of exponents are expressed as shown below;
1) a^-n = 1/a^n
In order to answer the given questions, we will use the following properties above;
3^-4 = 1/3^4 where a is equivalent to 3 and n is equivalent to 4
Similarly;
1/2^3 = 2^-3 = 1/8
For the expression 1/3^-2
1/3^-2 = 1/(1/3^2)
1/3^-2 = 3^2
For the expression 5^-1
5^-1 = 1/5^1
5^-1 = 1/5
Also for 1/5^2
1/5^2 = 1/25 = 5^-2
Hence the result of the given exponential expression is given as 1/8, 3^2, 1/5 and 5^-2

Answer:
Don’t see any pictures
Step-by-step explanation:
First, you would need to determine how many questions he got correct.
30 - 12 = 18
Next, you would need to create an equation for this problem. Let x represent the unknown percentage.
=
Now, you would cross multiply.
30x = 1,800
The last step would be to isolate the x. To do this, you would divide both sides of the equal sign by 30.
x =
60Ahmad got 60% of the questions correct. I hope this helps!
Answer:
1.5
Step-by-step explanation:
-0.4=g/3-0.9. -0.4+0.9. add 0.9 to both sides. 0.5=g/3. 0.5 times 3= 1.5.
