The answer is the D ( the last one)
Try this option:
the final price of the first machine after discount is:
(1-0.3)*495=346.5$;
the final price of the second machine after all the discount is:
(1-(0.2+0.2*0.1))*495=386.1$.
Short explanation: the additional 10% off is 2% of the initial price for the second machine; the final discount of the second machine is 22%.
4:7
Step-by-step explanation:
The ratio of the number of corn tortillas to flour tortillas is 3:4. So this means there are at least 3 corn tortillas and 4 flour tortillas.
We need to add 3 and 4 to see the simplified total of tortillas. 3+4=7.
There is a total of 7 tortillas regardless of their type.
Now we just need to compare this with the number they already gave us for flour tortillas, which is 4.
4:7 or 4 flour:7 in total
The ratio of flour tortillas to total tortillas is 4:7.
Answer:
Step-by-step explanation:
Without loss of generality, let 
and 
(follows tan(C)=2.4). In a right triangle, the tangent of an angle is equal to its opposite side divided by its adjacent side and the cosine of an angle is equal to its adjacent side divided by the hypotenuse.
We can use the Pythagorean Theorem (
, where 
is the hypotenuse) to solve for the hypotenuse:
Therefore,
