Answer:

14.4 ft

Step-by-step explanation:

The triangles formed by both ladders are similar to each other. Therefore, each corresponding sides will be proportional.

Thus, x + 8 would represent how far up the 10-foot ladder reaches the wall.

Therefore:

18/10 = (x + 8)/8

9/5 = (x + 8)/8

Cross multiply

9*8 = 5(x + 8)

72 = 5x + 40

72 - 40 = 5x

32 = 5x

Divide both sides by 5

32/5 = x

x = 6.4

The 10-foot ladder would be, 6.4 + 8 = 14.4 ft far up the wall.

How do you figure out what 1/10 of 1,7000.000 km squared is?
Sergeu [11.5K]
The first thing you would do is square 17,000, which is 298,000,000. Then you would multiply 298,000,000 by 0.10. (or divide the number by 10)

This would get you 28,900,000.

Write the equation in slope-intercept form of the line that has a slope of 6 and contains the point (1, 1).
valentinak56 [21]

Answer: y=6x-5

Step-by-step explanation:

Since we know the slope, we can plug it into the slope-intercept equation. We can plug in the given point to find the y-intercept.

y=6x+b

1=6(1)+b

1=6+b

b=-5

Now that we know the y-intercept, we can complete the equation.

y=6x-5
