250 divided by 3 = 83.3 repeating decimal :)
Hope this helps you.
Answer:
answer is 26.6%
Step-by-step explanation:
i first converted the fraction "40/150" to a decimal by dividing 40 by 150
40 divided by 150 is .26 (rounded)
and then i did .26 times 100
which gave me 26.6
:P hope this helped even doe im kinda late-
The equation of the perpendicular line is y + 7 = -1/7(x - 3)
<h3>How to determine the line equation?</h3>
The equation is given as
y = 7x + 14
Also, from the question
The point is given as
Point = (3, -7)
The equation of a line can be represented as
y = mx + c
Where
Slope = m
By comparing the equations, we have the following
m = 7
This means that the slope of y = 7x + 14 is 7
So, we have
m = 7
The slopes of perpendicular lines are opposite reciprocals
This means that the slope of the other line is -1/7
The equation of the perpendicular lines is then calculated as
y = m(x - x₁) +y₁
Where
m = -1/7
(x₁, y₁) = (3, -7)
So, we have
y = -1/7(x - 3) - 7
Evaluate
y = -1/7(x - 3) - 7
Add 7 to both sides
y + 7 = -1/7(x - 3)
Hence, the perpendicular line has an equation of y + 7 = -1/7(x - 3)

Using cosine rule, the length of side t is 31.5 unit
<h3>Cosine Rule</h3>
Cosine rule states that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.
The formula is given as
t² = s² + u² -3su cos(T)
let's define our variables
- t = ?
- s = 34
- u = 40.5
- T = 49 degrees
substituting the values into the formula
t² = 34² + 40.5² -2(34)(40.5)cos49
t² = 1156 + 1640.25 - 1806.79
t² = 989.46
t = √989.46
t = 31.5
The length of t is 31.5 unit
