No.
You may see it without computations: if 12 out of 20 doctors agree, it means that a bit more than half of the doctors agree (half of the doctors would be 10 out of 20).
In the second case, exactly half of the doctors agree, since 15 if the half of 30.
So, in the first case you have than more than half the doctors agree, while in the second case exactly half of the doctors agree.
Anyway, you can obviously perform more rigorous computations as well, and you have different methods available:
You can transform both ratios to have the same denominator:
And obviously
You can check the inequality by cross multiplying denominators:
You can convert fractions to decimal numbers:
Step-by-step explanation:
so first you have 8 and 6 and a triangle the third side should be a equal number it should me 14 combined but I dont know if im wrong but the other side should me 7×2 which is 14
The area formula for a rectangle is A = L*W. We have the area as 3197, now we just have to find a way to directly relate the length to the width with only one unknown, since we can't have 2 unknowns. The problem tells us that the length is 22 in. less than 7xW. That will be expressed as L=7W-22, and width is just W. Filling in we have 3197=W(7W-22). Distributing through the parenthesis we have
. Since we have to solve for x and the only way we can do that is by factoring, we will move the 3197 over to the other side by subtraction and then factor the quadratic.
. I recommend putting that into the quadratic formula, and when you do you get W values of 23 and -19.857 The only 2 things in math that will never EVER be negative are time and distance/length. And since one of our lengths there is negative we know that that is not the one we will use. Therefore, the width is 23. The length then is L=7(23)-22 which is 139

Answer:
x = 88.2
Step-by-step explanation:
The angle at the top of the triangle = 90° - 10° = 80°
and the left side of the triangle is x ( opposite sides of a rectangle )
Using the tangent ratio in the right triangle
tan80° = =
Multiply both sides by x
x × tan80° = 500 ( divide both sides by tan80° )
x = ≈ 88.2
