Answer:

The answer is 54.

Step-by-step explanation:

Ok buddy

‣Remember that a right angle equals 90 degrees.

‣The numbers lie on a right angle.

‣So watchya gonna do is combine the like terms.

$x + 2x + 2x = 5x$

‣In an equation, that finna look like:

$5x = 90$

‣Solve that equation

$\frac{5x}{5} = \frac{90}{5} \\ \\ x = 18$

‣Therefore, the value of x is 18.

‣We trynna find 3x so plug it.

$3x \\ 3(18) \\ 54$

‣That fr is the answer, 54.

A trough is 12 ft long and its ends have the shape of isosceles triangles that are 3 ft across at the top and have a height of 1

V125BC [204]

Answer:

$\frac{dh}{dt}=0.5ft$

Step-by-step explanation:

From the question we are told that:

Length $l=12$

Top length $l_t=3ft$

Height $h=1ft$

Rate $R=14 ft3/min$

Water rise $w=4$

Generally the equation for Velocity is mathematically given by

$V=frac{1}{2}wh'(l)\\\\V=frac{1}{2}wh'(12)$

$V=18h'^2$

Therefore

$R=18(2h)(\frac{dh}{dt})$

Where

$h=\frac{3}{4}$

Therefore

$\frac{dh}{dt}=\frac{R}{18(2h)}$

$\frac{dh}{dt}=\frac{14}{18(2.3/4)}$

$\frac{dh}{dt}=0.5ft$

Answer: 8/145

Step-by-step explanation: Rewriting the table

Positive and Negative stand for the result of the test

Yes and No stand for having the disease

Positive | Negative | Total

Yes | 137 | 8 | 145

No | 16 | 139 | 155

Total | 153 | 147 | 300

probability of getting someone who tests negative, given that he or she had the disease.

P(Negative | Yes) = P(Negative ∩ Yes) = 8

P(Yes) 145
