Answer: 10/36
Step-by-step explanation:
Answer:
y=-3/4x+3
Step-by-step explanation:
subtract 3x from both sides: 4y=-3x+12
Divide both sides by 4: y=-3/4y+3
The volume of titanium is 20.86 cubic inches
<em><u>Solution:</u></em>
The volume is given by formula:

From given,
Density of titanium = 4.51 
Mass = 3.4 lb
Let us convert the mass to grams
1 pound = 453.592 grams
Therefore, 3.4 pound is equal to:

Now substitute the values into formula:

Let us convert cubic centimeter to cubic inches
1 cubic centimeter = 0.0610237 cubic inches
Therefore,

Thus volume of titanium is 20.86 cubic inches
Answer:
30°
Step-by-step explanation:
∠A + ∠B + ∠C = 180
∠B = ∠A + 20
∠C = 2 * ∠B
<A + (∠A + 20) + (2 * ∠B) = 180
<A + (∠A + 20) + (2 * (∠A + 20)) = 180
<A + (∠A + 20) + 2∠A + 40 = 180
4∠A + 60 = 180
4∠A = 120
∠A = 30
