Answer:

?= 63.15789474%

Step-by-step explanation:

Use cross multiply

Set ?=x

57 \times x = 100 \times 36 \\ 57x = 3600 \\  \frac{57x}{57}  =  \frac{3600}{57}  \\ x =  \frac{3600}{57} \\ x = 63.15789474

The base of a 15-foot ladder is 6 feet from a building. If the ladder reaches the flat roof, how tall is the building?
Vlad [161]

Answer:

the answer would be 13.75 feet

Step-by-step explanation:

The computation of the tall is the building as follows:

Given that

Base is 6 foot

And, the hypotheses is 15 feet

Here we use the Pythagoras theorem

= √15^2 - √6^2

= √225 - √36

= √189

= 13.75 feet

Hence the answer would be 13.75 feet

15 points!
Phantasy [73]

Hi there! You are provided with two points, this is all you need to calculate the line's slope.


The equation for slope is:

\frac{y2 - y1}{x2 - x1}

\frac{10 - 8}{3 - 7} = -\frac{2}{4}

Slope: -2/4


Point slope form, or y-y1 = m(x - x1). All we have to do is take the x and y coordinates of either point, as well as the slope, and plug them into the equation.

y - 10 = -2/4(x - 3)


Write the equation in slope-intercept form (y=mx+b)

y - 10 = -2/4(x-3)\\y = -2/4(x-3) + 10\\y = -2/4x + 1.5 + 10\\y = -2/4x + 11.5


A) -2/4

B) y - 10 = -2/4(x - 3)

C) y = -2/4x + 11.5

Find an equation of the line parallel to −5x+7y=3 that passes through the point (9,−4). If possible, write the equation in slope
saul85 [17]

From the original equation we have:

-5x+7y=37y=5x+3y=\frac{5}{7}x+\frac{3}{7}

The slope of this line is 5/7 and for the new equation to be parallel to the original must have the same slope, and using the point-slope formula we have:

y-(-4)=\frac{5}{7}(x-9)y+4=\frac{5}{7}x-\frac{45}{7}y=\frac{5}{7}x-\frac{45}{7}-4y=\frac{5}{7}x-\frac{73}{7}
