Answer:
<h2>34 earrings</h2>
Step-by-step explanation:
Step one:
given that the total lenght of the wire is 25 1/2 inches
in decimal, this is 25.5 inches
we are told that each earring requires 3/4 in of wire
in decimal this 0.75 in
Step two:
<em>The number of earrings that can be mad is found by dividing the total length of wire by the length needed to make one earring</em>
The number of earrings that can be made is given as
=25.5/0.75
=34 earrings
Cos θ = adjacent / hypothenus = 5/13
opposite = sqrt(hypothenus^2 - adjacent^2) = sqrt(13^2 - 5^2) = sqrt(169 - 25) = sqrt(144) = 12
sec θ = 1/cos θ = 1/(adjacent / hypothenus) = hypothenus / adjacent = 13/5
cot θ = 1/tan θ = 1/(opposite/adjacent) = adjacent / opposite = 5/12
sec θ = 13/5
cot θ = 5/12
Answer:
Option A is correct.
The constant of variation is, 
Step-by-step explanation:
The Direct variation says that:
if a vary directly to b then, the equation is of the form: a = kb where k is the constant of variation.
Given: if y varies directly as x.
By definition of direct Variation:
y = kx where is the constant of variation.
It is also given that: y = -3 and x =2
Solve for k;
-3 = 2k
Divide both sides by 2 we have;
Therefore, the constant of variation is,
Answer:
good luck on the assignment
Step-by-step explanation:
Answer:
Each CD cost $20.50
Step-by-step explanation:
You would divide the cost of the DVDs by 4: 164÷4=41
Now the CDs are half the cost of the DVDs so you would divide 41 by 2: 41÷2=20.50
Your answer would be $20.50
