balandron [24]

Answer:The answer is 25 units.

so, the given triangle is an isosceles triangle.

this means side AB and side AC are equal

so, you can write 4x+4=6x-14

solving this equation, we get x=9

finally, BC=2x+7=2*9+7=25

A pot of stew is placed on a stove to heat. The temperature of the liquid reaches 170°F, and then the pot is taken off the burne

belka [17]

Answer:

$T =84.7\°F$

Step-by-step explanation:

Newton's cooling model is:

$T(t) =T_0 + (T_i-T_0)e^{-kt}$

Where

t is the time in hours

$T_0$ is the ambient temperature

$T_i$ is the initial temperature of the body

$k=0.34$

We know that:

$T_0=76\°F$

$T_i=170\°F$

Then after 7 hours the temperature of the liquid will be:

$T(7) =76 + (170-76)e^{-0.34(7)}$

$T =84.7\°F$

What is the volume of the following triangular prism?

sergiy2304 [10]

Answer:

<h2>288 ft³</h2>

Step-by-step explanation:

The formula of a volume of a prism:

$V=BH$

where

<em>B</em><em> - area of a base</em>

<em>H</em><em> - height of a prism</em>

<em />

In the base we have the right treiangle. The formula of an area of a right triangle is:

$A=\dfrac{ab}{2}$

where

<em>a, b</em><em> - are legs</em>

We have

$a=6\ ft,\ b=8\ ft$

Substitute:

$B=\dfrac{(6)(8)}{2}=\dfrac{48}{2}=24\ ft^2$

Calculate the volume.

Substitute

$B=24\ ft^2,\ H=12\ ft$

$V=(24)(12)=288\ ft^3$
