If it costs $1.30 a square foot to lay linoleum, what
will be the cost of laying 20 square yards of linoleum?
(3 ft. = 1 yd.)
A.
B.
c.
$26.00
$78.00
$156,00
D.
$234.00

The cost of laying 20 square yards of linoleum is option B) $78

Step-by-step explanation:

Given that,

cost of 1 square foot = $1.30

1 yard = 3 feet.

The cost of laying 20 square yards of linoleum = $78

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
