<span>The roof is higher than the ladder can reach
10^2-1.5^2=h^2
h=sqrt(100-2.25)=9.89 feet
distance to the roof= 12-9.89</span>
Answer:
-2(9x-8)
Step-by-step explanation:
We are to simplify the expression -3.1x+7-7.4x-1.5x-6(x-3/2)
Open the parenthesis
-3.1x+7-7.4x-1.5x-6(x-3/2)
= -3.1x+7-7.4x-1.5x-6x+6(3/2)
= -3.1x+7-7.4x-1.5x-6x+9
Collect like terms
= -3.1x-7.4x-1.5x-6x+7+9
= -12x-6x+16
= -18x+16
= -2(9x-8)
Hence the simplified form of the expression is -2(9x-8)
Answer:
k = 0.28
Step-by-step explanation:
The price of peaches at Al's supermarket can be determined by the equation P = 0.28n ........... (1)
where P is the price and n is the number of pounds of peaches.
Now, it is clear that the price of peaches is proportional to the number of pounds of peaches.
So, we can write,
P ∝ n
⇒ P = kn ............. (2) where k is the constant which we have to multiply to covert from proportionality to equation form.
Now, comparing equations (1) and (2) we get k = 0.28 which is the value of the constant of proportionality. (Answer)
20000000+ 4000000+ 80000+ 4000+ 100+ 60+ 3
