Answer:

$1440

Step-by-step explanation:

First find the the area with feet.

18*16=288

Now convert into sq. yards

288/3=96

Finally, multiply 96 by 15

96*15=1440

Answer:

$1440

Step-by-step explanation:

It will cost $1440 to carpet a rectangular floor 18 by 16 feet if the carpet costs $15 a square yard.

18 feet ⋅ 16 feet = 288

288 feet ÷ 3 = 96

96 ⋅ 15 = 1440

In the figure, lines a, b, and c are parallel and m∠4=68° . Drag and drop the correct angle measure for each angle. m∠1 = m∠2 =

The complete question in the attached figure

we have that
<span>m∠4=68°

we know that
</span>m∠4 and m∠3 are supplementary angles
so
m∠3=180-m∠4----- m∠3=180-68------> m∠3=112°

m∠3 = m∠2 --------> by alternate interior angles
so
m∠2=112°

m∠1 = m∠4 --------> by alternate exterior angles
so
m∠1=68°

m∠5 = m∠4---------> by corresponding angles
so
m∠5=68°

the answers are
m∠1=68°
m∠2=112
m∠3=112°
m∠5=68°
