1/56 divided by -30 write fractions is simplest form

Nady [450]

Simplified form of 1/56 divided by -30 is $=-\frac{1}{1680}$

Step-by-step explanation:

We need to solve 1/56 divided by -30 in simplest form.

Solving:

Writing in mathematical form:

$\frac{1}{56}\div -30$

Converting division symbol into multiplication and taking reciprocal of -30

$=\frac{1}{56}\times \frac{1}{-30}$

Simplifying:

$=\frac{1}{56*-30}$

$=-\frac{1}{1680}$

So, simplified form of 1/56 divided by -30 is $=-\frac{1}{1680}$

Answer: 114.37 ft

Step-by-step explanation:

If we model this situation as a right triangle, where the hypotenuse is the length of the ladder ( $110 ft$ ), the opposite leg is the height the ladder will reach $h$ , and the adjacent leg is the distance between the base of the ladder and the building ( $28 ft$ ); we have two options:

1) Using trigonometric functions, since we are given the angle $\theta=75\°$

2) Using the Pithagorean Theorem

Any of the options will give a similiar result. So, let's choose the Pithagorean Theorem:

$(hypotenuse)^{2}=(opposite-leg)^{2}+(adjacent-leg)^{2}$

$(110 ft)^{2}=(h)^{2}+(28 ft)^{2}$

Isolating $h$ :

$h=\sqrt{(110 ft)^{2}-(28 ft)^{2}}$

$h=106.37 ft$

Adding to this height the extra height of $8 ft$ (since the base of the ladder is at this distance above the ground, perhaps held by a firefighter truck):
