Answer:

15 feet..

taking base as 8m

Given: ladder = 17 m and base = 8 m

The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.

Let’s say you did not know that this was a standard 8–15–17 right triangle.

This is how you can figure it out:

hypotenuse(h)22 = side2112 + side2222

Let side11 = base and side22 = wall

1722 = 822 + wall22

wall = 172−82−−−−−−−√172−82

wall = 289−64−−−−−−−√289−64

wall = 225−−−√225

wall = 15 feet

Height of wall is 15 feet

Given:

Length of ladder = 17 feet

Base distance from ladder = 8 feet (Missing information)

Find:

Height of wall

Computation:

Length of ladder = hypotenuse

Base distance from ladder = Base

Height of wall = Perpendicular

Using Pythagorean theorem

[tex]Perpendicular = \sqrt{Hypotenuse^2 - Base^2}[/tex]

By putting values

[tex]Perpendicular = \sqrt{17^2 - 8^2}[/tex]

[tex]Perpendicular = \sqrt{289 - 64} \\\\Perpendicular = \sqrt{225} \\\\Perpendicular = 15[/tex]

Height of wall = 15 feet

Answer:

20%

Step-by-step explanation:

Because 144 OUT OF the 180 seventh grade students attended, this would represent 144/180.

But since we are trying to solve how many did NOT attend the dance, you must subtract 144 from 180 which equals 36. So 36/180 did not attend the dance.

But to make it a percentage, you divide 36/180. Fraction and percentage are like buddies! That's why it is very simple to make a fraction into a percentage.

36/180 can be simplified to 1/5, which as a decimal, is 0.20.

0.20 is same as 20%, so this should be the students that did not attend the dance.

I hope this helps. If this is wrong, I truly apologize...

Answer:20

Step-by-step explanation:

20

Answer:

we have

slope=(-5--8)/(x-7)

-3/4=3/(x-7)

-3(x-7)=3×4

-3x+21=12

21-12=3x

3x=9

x=9/3=3

Answer:

x = 3

Step-by-step explanation:

slope = [tex]\frac{y_{2} - y_{1} }{x_{2} -x_{1} }[/tex]

Using the your two points the slope = m = [tex]\frac{-8 + 5}{7-x} = \frac{-3}{4}[/tex]

                                                                       [tex]\frac{-3}{7-x} =\frac{-3}{4}[/tex]

Since the numerators are equal, then the denominators must be equal.

So, 7 - x = 4

-x = -3

x = 3

Answer:

y divided by 6 1/4 = 11 3/4

Step-by-step explanation:

First, change the mixed numbers into improper fractions:

y divided by 25/4 = 47/4

Next, multiply both sides by 25/4:

y divided by 25/4 x 25/4 = 47/4 x 25/4

The 25/4's on the left side of the equation cancel each other out, leaving you with:

y = 47/4 x 25/4

Multiply 47 x 25 and keep the same denominator:

y = 1,175/4

Divide and:

y = 293 3/4
