Answer:
Its 10:4 so its 5:2 when dividing
5:2 is the answer
I have a pizza cut into fifths. I give 1/5 to a friend. Then my friend gives me 2/5 of a pizza back. How many slices of pizza do I have left?
Since we know that The angle of depression from the airplane to the airport is 40°, and its altitude is 10000 feet, we can create a right triangle using the horizontal of the plane, the angle of depression, and the altitude as one of the legs of our right triangle. the horizontal (ground distance) from the airport to the airplane's<span> will be the same as the adjacent leg of our depression angle. To find the adjacent leg we'll need a trig function that relates our leg with the depression angle and the opposite leg. That trig function is tangent. So lets set up an equation and solve it to find our distance:
</span>
<span>
We can conclude that </span><span>the horizontal (ground distance) from the airport to the airplane's position is
11,917.54 feet.</span>
Answer:
-15
Step-by-step explanation:
We proceed as follows;
In this question, we want to fill in the blank so that we can have the resulting expression expressed as the product of two different linear expressions.
Now, what to do here is that, when we factor the first two expressions, we need the same kind of expression to be present in the second bracket.
Thus, we have;
2a(b-3) + 5b + _
Now, putting -15 will give us the same expression in the first bracket and this gives us the following;
2a(b-3) + 5b-15
2a(b-3) + 5(b-3)
So we can have ; (2a+5)(b-3)
Hence the constant used is -15
Answer:
x=2 or x=1 where x is integer.
Step-by-step explanation:
even numbers are the multiple of 2 or which are perfectly divided by 2 i.e. 2,4,6 etc.
Let 'x' be the first even number and 'x+2' be the second even number.
now translate the given sentence into mathematical order we write as.
x*(x+2)=5x-2
now simplify for x we get the integer.
x*x+2x=5x-2
=5x-2x-2
=3x-2
-3x+2=0
since above eqn is quadratic i.e. having greater power is 2, so using quadratic formula or middle term braking or completing square we get the value of x or integer.
using middle term braking we get the values of integers.
-2x-1x+2=0
x(x-2)-1(x-2)=0
(x-2)(x-1)=0
x-2=0 and x-1=0
x=2 or x=1
verification
2*4=10-2
8=8
