Eight oranges cost $1.00.How much will 5 dozen oranges cost?

Nutka1998 [239]

1 dollar is to 8
1:8
so 5 dozen
1 dozen=12
5 dozen=12 times 5=60
1:8 and x:60
1/8=x/60
multiply both sides by 60
60/8=x
30/4=15/2=7.5=x
$7.50 is how much you pay

What is the answer for AC =

Triss [41]

Answer:

The length of AC is 2.33 units.

Step-by-step explanation:

You have to use Tangent Rule, tanθ = opposite/adjacent :

$\tan(θ) = \frac{oppo.}{adj.}$

Let oppo. = AC,

Let adj. = BC = 5,

Let θ = 25°,

$\tan(25) = \frac{ac}{5}$

$ac = 5 \tan(25)$

$ac = 2.33 \: units \: (near.hundredth)$
