Answer:

3ft

Step-by-step explanation:

c^2 = a^2 + b^2 so, we have c = 5ft, and lets call this one a = 4ft

so: x^2 = 5^2 - 4^2 => x = sqrt(25 - 16) => x = 3ft

If you flip a fair coin 10 times and it lands heads up 5 times, this would result in 50% probability of the coin landing heads u

Shtirlitz [24]

This is an example of empirical probability, although it gives the same ratio as a theoretical probability, because we based the result on our experiment

The following picture is a square pyramid where DE=8 cm and m∠ADE=60°.

mr_godi [17]

Answer:

131 cm

Step-by-step explanation:

formula for surface area of pyramid is

S = (1/3)Bh

but the base ia a square, so B = $x^{2}$

S = (1/3) $x^{2} h$

the pic shows h = 8

but we don't know x

do SohCahToa

sin60 = x/8

x = 8sin60

x = 6.92820323 or 7

plug in numbers

S = (1/3) $7^{2}$ 8

S = 392/3

S = 130.6666667 or 131 cm

Write the equation of a line that is parallel to 3x+2y=10 and passes through the point (4,-5). Answer in slope-intercept form.

SCORPION-xisa [38]

The equation of line is:

$y = \frac{-3}{2}x+1$

Further explanation:

The standard form of equation in point-slope form is:

$y = mx+b$

Given equation is:

3x+2y=10

We have to convert it into point slope form, for which we have to isolate y on one side of equation

$3x+2y = 10\\2y = -3x +10\\y = \frac{-3}{2}x + \frac{10}{2}\\y = \frac{-3}{2}x + 5$

Comparing with standard form:

m = -3/2

As the new line is parallel to given line, their slopes will be equal

So,

$y = \frac{-3}{2}x+b$

To find the value of b, putting the given point (4,-5) in equation

$-5 = \frac{-3}{2}(4)+b\\-5 = -6+b\\b = -5+6 \\b = 1\\So\ the\ equation\ is:\\y = \frac{-3}{2}x+1$
