Answer:

The correct option is option number 4. Parallel lines are defined as lines that never have one point in common.

Step-by-step explanation:

Parallel lines: Parallel lines are the lines that will never cross each other. As they never meet, so they won't have a common point.

On the other hand, the other options are incorrect. This is because,

Perpendicular lines: Perpendicular lines are the lines that make 90 degrees angle with each other.

Skew lines: Skew lines are the lines that are not present on the same plane.

Coplanar lines: Any lines which are known to occur on the same plane are termed as coplanar lines.

Arturiano [62]

Answer: 7 5/7 (the bottom one)

Step-by-step explanation:

30 divided by 2 = 15 (do the same to 42 and get 21)

This then creates the fraction: 15/21

Now, divide this fraction by 3 and get 5/7

Add back in the seven because you aren't dividing the whole number.

Your final answer is now 7 and 5/7 (together: 7 5/7)

Answer:

927.0 cm²

Step-by-step explanation:

Step 1: find Z

m < Z = 180 - (28 + 118) (sum of ∆)

= 180 - 146

Z = 34°

Step 2: Find side XY using the law of sines

$\frac{XY}{sin(34)} = \frac{42}{sin(28)}$

Cross multiply

$XY*sin(28) = 42*sin(34)$

$XY*0.469 = 42*0.559$

Divide both sides by 0.469

$\frac{XY*0.469}{0.469} = \frac{42*0.559}{0.469}$

$XY = 50.06$

XY ≈ 50 cm

Step 3: find the area.

Area of ∆ = ½*XY*YZ*sin(Y)

XY ≈ 50 cm

= ½*50*42*sin(118)

= 25*42*0.8829

Area = 927.045

Area ≈ 927.0 cm² (nearest tenth)

A pair of jeans originally cost $80, but is on sale for 30% off. there is a coupon available for an additional 10% off of the sa

Lady_Fox [76]

30% = 0.3.

0.3*80 = 24, so we know that 30% of 80 is 24.

80 - 24 = 56, so after the sale, the price for a pair of jeans is $56.

10% = 0.1

0.1*56 = 5.6, so with the coupon, we get $5.60 off.

56 - 5.60 = 50.40

The jeans cost $50.40 after the sale and the coupon.
