Answer:
It costs $51
Expression:
16x = 68
12x = ?
Step-by-step explanation:
Lets first find out how much one sq. ft. of flooring costs:
16x = $68
x = $68/16 = $4.25
Next, lets multiply the unit rate by 12 to find the answer:
12x = Answer
12 * (4.25) = $51
Answer:
Step-by-step explanation:
0.009 i think this is the answer
Converting 9 3/8 to an improper fraction is 75/8. Converting 8 7/8 to an improper fraction is 71/8. Subtracting these, we get 75/8 - 71/8 = 4/8 = 1/2.

B. c = ((3)sin45°)/sin40°
Side a is given information: 3cm, and we can find angle A (which is the angle opposite side a) by subtracting the other two angles from 180 because the total interior angle measures of a triangle add to equal 180°.
Angle A = 180 - (95+45) = 40°.
This can be substituted into the equation for the law of sines.
sin(40)°/3 = sin(45)°/c
—Cross multiply
c•sin(40)° = 3•sin(45)°
—divide both sides by sin40 to get the variable c alone and we get:
c = (3)sin(45°)/sin(40°)
this also simplifies to 3.3 cm.
