Hello.
Remember the Property of exponents:
Let's use it to solve our maths problem.
Subtract the exponents:
Therefore, the answer is
c.
I hope it helps.
Have a nice day.
The vertex angle bisector divides the triangle into two congruent right triangles. The sine of half of the vertex angle will be half of the base divided by the side (from the definition of the sine of an angle). Then the total vertex angle is ...
α = 2×arcsin(3.5/5) ≈ 88.9°
_____
Using the Law of Cosines, the vertex angle can be found as
arccos((7^2 -5^2 -5^2)/(-2*5*5)) = arccos(1/50) ≈ 88.9°
Based on the given parameters, the value of Rx is R18
<h3>How to determine the value of Rx?</h3>
The given parameters are:
Number of people = 25
Amount paid = Rx
Additional people of 5 = Amount paid being R3 less
The total amount paid is calculated using:
Total amount = Number of people * Amount paid
Substitute the known values in the above equation
Total amount = 25 * x
Total amount = (25 + 5) * (x - 3)
Substitute Total amount = (25 + 5) * (x - 3) in Total amount = 25 * x
(25 + 5) * (x - 3) = 25 * x
Evaluate the sum
30 * (x - 3) = 25 * x
Evaluate the products
30x - 90 = 25x
Collect like terms
30x - 25x = 90
Evaluate the like terms
5x = 90
Divide both sides by 5
x = 18
Hence, the value of Rx is R18

The expected value for the game would be the first one negative three
Answer:
5.6
Step-by-step explanation:
let ‘x’ denotes the weight of smaller dog.
“1.4″ + x” be weight of larger dog
combined weight = 12.6
smaller dog weight =
x+x+1.4 = 12.6
2x + 1.4 = 12.6
2x = 12.6–1.4
2x = 11.2
x = 11.2/2
x = 5.6
