Answer:
33% discount
Step-by-step explanation:
15$ is the amount that was taken off so now we just need to convert it to a % of 45
45/100 = 30/?
if you do cross multiplication and multiply 30 * 100 then divide the result (3000) by 45 you get 66
This means that 30$ is 66% of 45. To find the discount you just subtract 66% (this represents your 30$ new price) from 100% (this represents the 45% original price) and you get 33%.

Answer:
x = 816 kilometers per hour.
Step-by-step explanation:
Given the following data;
Distance traveled by Kirk = 450km
Distance traveled by Thor = 408 km
Let the average driving speed of Thor be x.
Translating the word problem into an algebraic equation;
k = x + 6
We know that the time taken to cover a distance by an object with speed is given by the formula;
Time = distance/speed
Substituting into the equation, we have;
408/x = 405/x + 6
Cross-multiplying, we have;
408*(x + 6) = 405*x
408x + 2448 = 405x
408x - 405x = 2448
3x = 2448
x = 2448/3
x = 816 kilometers per hour.
Answer:
x = 113°
Step-by-step explanation:
the sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
here n = 6 , then
sum = 180° × 4 = 720°
sum the given angles and equate to 720°
97° + 146° + 134° + 103° + 127° + x = 720°
607° + x = 720° ( subtract 607° from both sides )
x = 113°
