The number are <span>(−5.4) and (+8.2).
Sum of these two numbers are = </span><span>(−5.4) + (+8.2)
= -5.4 + 8.2
= 2.8
Now we are going to add this to the opposite number of </span><span>(−2 3/4 ).
</span><span>(−2 3/4 ) = -11/4 = -2.75
now opposite number of -2.75 is 2.75
Thus,
2.8 + (2.75)
= 2.8 + 2.75
= 5.55</span>
Answer:
156250
Step-by-step explanation:
10000(1+.5/2 )^2*10=156250
Answer:
Step-by-step explanation:
we know that
The formula of the law of cosines is equal to
where
a, b and c are sides. C is the angle opposite side c
In this context
The formula to calculate the measure of angle X is equal to
substitute the given values
solve for cos(X)
Ratio = 1:3
or in other words = sale price:original price
Therefore, it'd look like this = sale price:$81
So to work out the original price, you'd do $81 divided by 3 (81 ÷ 3 = $27).
The sale price is $27..
Answer:
<h2>AB = 8x+10</h2>
Step-by-step explanation:
If M is the midpoint of the segment AB, then <em>AM+MB = AB</em>. Given the following parameters;
AM=9x-5 and MB=15-x
Required parameter
segemnt AB
Substituting the given parameters into the given formula to get AB we will have;
AB = AM+MB
AB = 9x-5+15-x
collect like terms
AB = 9x-x-5+15
AB = 8x+10
<em>Hence the length of segment AB is 8x+10</em>
