Mary French uses gas to heat her home. She has accumulated the following information regarding her monthly gas bill and monthly

garik1379 [7]

Answer:

$Y=$24+0.09X$

Step-by-step explanation:

From the question we are told that

February Heat $H_1=1900\textdegree$

February Gas $G_1 =\$195$

April Heat $H_2=600\textdegree$

April Gas $G_2=\$78$

Generally equation for heating degree-days X is mathematically given by

$X=\frac{\triangle gas\ bills}{\triangle Heating\ days}$

$X=\frac{195-78}{1900-600}$

$X=\$ 0.09$

Generally the equation for gas bill Y is mathematically represented by

$Y=78-(600*0.09)\\Y=\$24$

The equation representing the relationship between the gas bill (Y) and heating degree-days (X) is

$Y=$24+0.09X$

What is the sector with a central angle of 185 degrees and a diameter of 6.4 m? Round to the nearest tenth.

mr_godi [17]

The area of a sector is
$A=\frac{1}{2}r^2\theta =\frac{1}{2}\left(3.2\:m\right)^2\left(185\cdot \frac{\pi }{180}\right)=16.5\:m^2$

The answer is 16.5 square meters.

In the figure, if m∠ABD = 120º, then m∠ADC = ___

Darya [45]

Okay first, use the sin rule ( $\frac{SinA}{a} = \frac{SinB}{b}$
so $\frac{Sin120}{35} * 30 = SinB$
sin^-1 this and you get 47.928....this is angle ADB
and as it is on a straight line, 180 - this angle gets ADC
180 - 47.928.... = 132.07

Two trains leave the same station at the same time, but are headed in opposite directions. One train travels at 70 mph and the o

uranmaximum [27]

Let

x--------> the time in hours

y-------> the distance in miles

we know that

The speed is equal to

$Speed=\frac{distance}{time}$

in this problem

$Speed=\frac{y}{x}$

$y=(Speed)*x$

<u>Equation First Train</u>

$y1=70x$

<u>Equation Second Train</u>

$y2=80x$

$y1+y2=600\ miles$ ---------> equation $1$

Substitute the values of $y1$ and $y2$ in the equation $1$

$70x+80x=600$

Solve for x

$150x=600$

$x=4\ hours$

therefore

<u>the answer is</u>

$4\ hours$
