Answer:
x ≈ 1.4
Step-by-step explanation:
Using the sine ratio in the right triangle
sin50° = 
= 
= 
( multiply both sides by 1.8 )
1.8 × sin50° = x , then
x ≈ 1.4 ( to the nearest tenth )
Answer:
I think it is -10
Step-by-step explanation:
Using a^m*a^n=a^(m+n)
b=(m+n)
In this question,
m= -8 and n= -2
so b= (m+n)=(-8+-2) = -10
8 kilometers=8000 meters 1.5 kilometers=1500 meters 500 meters 8000+1500+500=10000 meters
The unit price of the disk is $0.549
<h3>Unit price of goods</h3>
The unit price of goods are the price of one portion of the goods in question.
From the given question, a package of blank compact discs on sale at 10 for $5.49, this can be expressed as;
10 disc = $5.49
The unit price of the disc is the price of just one of the disc. The unit price is expressed as;
1 disc = x
Find the ratio
10/1 = 5.49/x
Cross multiply
10x = 5.49
Divide both sides by 10
10x/10 = 5.49/10
x = $0.549
Hence the unit price of the disk is $0.549
