Answer: $4.79
Step-by-step explanation:
To find the unit price, we can use a proportion to solve.
[cross multiply]
[divide both sides by 8]
Now, we know that the unit price is $4.79 for each mug.
Answer:
Solution given:
sin 47=opposite/hypotenuse
Sin 47=x/18
x=sin47*18
<u>x=13.16ft</u>
First of all let's define Distributive Property. So, it is an algebra property which aims to multiply a single term or more terms to a set inside a parenthesis. In the case above,
the first thing to do is to multiply 4 to each term inside the parenthesis:
11+4(x+2y+4)
=11+4x+8y+16x
Then , you should combine like terms. Like terms have a whole number and the same variable in this case a whole number and x which is why:
=11+20x+8y
This is the final equivalent expression
Answer:
<h2>7. 62.8 sq.in.</h2><h2>8. 21.2 sq.in.</h2>
Step-by-step explanation:
The formula of an area of a triangle:
a, b - adjacent sides
θ - included angle
=============================================
7.
a = 9in, b = 14in, θ = 85°
sin85° ≈ 0.9962
Substitute:
8.
a = 12 in, b = 5 in, θ = 135°
sin135° = sin(180° - 45°) = sin45° ≈ 0.7071 <em>used sin(180° - x) = sin(x)</em>
Substitute:
