An electrician needs 18.25 feet of wire for each outlet she installs. How man can she install with a 50 ft spool of wire?

jolli1 [7]

Answer:

Step-by-step explanation:

Ok, so if we know how much wire is needed for one outlet, we must figure out how many 18.25s fit into 50 ft of wire.

18.25*2=36.5

18.25*3=54.75 which is over 50 so it cannot possibly be more than 2.

d = 32 miles
t = 2 1/3 hr = 7/3 hr

Find the rate s:

s = d/t
s = 32÷7/3 = 32 × 3/7 = 96/7 ≈ 13.7 mph (rounded)

The area of parallelogram WXYZ is approximately 45 square units.

neonofarm [45]

Answer:

Option (4)

Step-by-step explanation:

Area of a triangle = $\frac{1}{2} (a.b.\text{Sin}\theta)$

Where a and b are the sides of a triangle and θ is the angle between the sides a and b.

By this rule,

Area of ΔWZY = $\frac{1}{2}(\text{WZ}).(\text{YZ}).\text{Sin}(115)$

45 = $\frac{1}{2}(\text{YZ}).(10).\text{Sin}(115)$

9 = (YZ).Sin(115)°

YZ = $\frac{9}{\text{Sin}(115)}$

YZ = 9.93

Perimeter of parallelogram WXYZ = WX + XY + YZ + WZ

= 9.93 + 10 + 9.93 + 10

= 39.86

≈ 40 units

Therefore, perimeter of the parallelogram is 40 units.

Option (4) is the answer.
