Please help and thanks!
Leokris [45]

Answer:    D: 17.3

Step-by-step explanation:

I believe its D because the house and the ground is a 90 degree angle, and at 60 degree angle is a 20 foot ladder. alright then 90 plus 60 = 150 degrees.

then add the twenty foot ladder with each choice for the answer:

A: 20 + 6.1 = 26.1

B: 20 + 10.0 = 30

C: 20 + 14.1 = 34.1

D: 20 + 17.3 = 37.3

The answer would be D because it is the closer number to 150. Because it says " which is the closest height up the house the ladder reaches?" The answer is D the closest number. I HOPE THIS HELPS YOU! =D

How do you work out? (step by step please)<br> 2x-4≥6(x-1)
Tomtit [17]
2x-4 \geq 6(x-1)\\\\ 2x-4 \geq 6x-6 \\\\ 2x-6x \geq -6+4 \\\\-4x \geq -2 \ |:(-2) \\\\ 2x \leq 1 \\\\ x \leq \frac{1}{2} \\\\ \boxed{x= (-\infty; \frac{1}{2} ] }

Which two lines are parallel?<br> Which two lines are perpendicular?
lana66690 [7]

Answer:

see explanation

Step-by-step explanation:

Parallel lines have equal slopes

The product of the slopes of perpendicular lines = - 1

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

All the equations given are in slope- intercept form

y = 2x + 1 → with m = 2

y = \frac{1}{2} x - 4 → with m = \frac{1}{2}

y = x + 1 → with m = 1

y = - \frac{1}{x} x - 3 → with m = - \frac{1}{2}

y = 10 + x → y = x + 10 → with m = 1

Thus

y = x + 1 and y = 10 + x are Parallel since both have m = 1

y = 2x + 1 and y = - \frac{1}{2} x - 3 are Perpendicular since 2 × - \frac{1}{2} = - 1

postnew [5]

Answer:

B.

Step-by-step explanation:

We see (-10) repeating six times. This means the product would be 6(-10). To simplify this, 6 × (-10) = -60.
