58 plus tip of .20
so
58 times 0.2 = 11.6 is the tip
now we add tax (Presuming we son't tax the tip)
58 times 0.07 = 4.06 the tax
so its
58 + 11.6 + 4.06 = $73.66 total cost
Radian is pure measure based on the radius of the circle.
Therefore, the answer is = 57.30 degree
I completely forgot how to do this but maybe multiply the angles I’m so sorry
Answer:
I think the answer is 8 blue tiles and 20 green
Step-by-step explanation:
To keep the porportion multiply 2 blue tiles *4
then you need to take 5 green tiles *4
You get 8 blue tiles and 20 Green tiles, and added together you get 28 tiles
Let x be the amount (the volume in milliliters) of the 5% solution to be mixed.
Then the volume of the 1% solution is 100-x milliliters.
Then your "concentration" equation is
%280.01%2A%28100-x%29+%2B+0.05%2Ax%29%2F100 = 0.02,
or, equivalently,
100-x + 5*x = 200,
which implies
4x = 100 ----> x = 100%2Fx = 25.
Answer: 25 milliliters of the 5% solution must be mised with 100-25 = 75 milliliters of the 1% solution.
