Classica aplicação de regra de 3:
é dito que: 1 milha = 1,6km
Logo, eis a regra de 3:
milha km
1 -------- 1,6
X -------- 240
1,6X = 240.1
X = 240/1,6
<h3>X = 150milhas</h3><h3 />
Logo 240km equivalem a 150milhas
Answer:

Step-by-step explanation:
Polynomial =
.
Before determining the degree of the polynomial, let's open the parentheses using the distributive property .

Degree is the highest exponential power in a polynomial .
So, the degree of the given polynomial is 5.

Answer:
Last one: ⅗
Step-by-step explanation:
cosF = adjacent/hypotenuse
cosF = FD/FE
= 6/10
= 3/5
At a particular time, objects and their shadows are proportionate.
Therefore, in figure,
--- (1)
where AB is the height of the lighthouse, BC, its shadow and FD is the height of Zara and DE is her shadow.
From the given information,
BC = 36 feet
FD = 4 feet and DE = 3 feet
(1) becomes


AB = 48
Hence, the height of the lighthouse is 48 feet.
5 times a half is 2.5. You can't buy 2.5 boxes so you have to round it up to 3. You would need three boxes of nails.
