What is the simplified form of x+5/3x+4 + x+4/x+3

1 answer:

3 0

$x + \frac{5}{3}x + 4 + x + \frac{4}{x} + 3 \\ x + \frac{5x}{3}+ 4 + x + \frac{4}{x}+ 3 \\ (x + \frac{5x}{3} + x) + (4 + 3) + \frac{4}{x} \\ x = \frac{11x}{3} + 7 + \frac{4}{x}$

The Volume of a rectangular prism can be computed by using the formula V=LWH which shows an equation solving for W

Alexus [3.1K]

Answer:

W = $\frac{V}{LH}$

Step-by-step explanation:

given the formula V = LWH

to solve for W divide both sides by LH, hence

W = $\frac{V}{LH}$

A kite on a 100-foot string is fastened to the ground, making a 25° angle with the ground. To the nearest tenth of a foot, how h

lozanna [386]

Answer: 42.3 ft

<u>Step-by-step explanation:</u>

Draw a picture (see attachment)

Given: angle = 25°, hypotenuse = 100, opposite = ???

$\sin\theta=\dfrac{opposite}{hypotenuse}\quad \rightarrow \quad \sin25^o=\dfrac{y}{100}\quad \rightarrow \quad 100\ \sin 25^o=y\\$

$\large\boxed{42.3\ ft}=y$

Use the Empirical Rule to answer each question.

Oliga [24]

Step-by-step explanation:

(a)

the probability of parcels weighing 35oz or less is

0.841

the probability of parcels weighing 14oz or less is

0.023

the probability of parcels weighing between 14 and 35oz is the probabilty of 35oz minus the probability of 14oz

0.841 - 0.023 = 0.818

the percentage is the probability × 100 = 81.8%

(b)

the probability of parcels weighing more than 49oz is 1 minus the probability to weigh less than 49oz.

the probability to weigh less than 49oz is

0.99865

so, the probability to weigh more than 49oz is

1 - 0.99865 = 0.00135

the percentage is again probability×100 = 0.14%
