Each month, you get your water bill in the mail. You know that each month you are charged a service
Svetach [21]

Answer:

$0.004 per gallon

Step-by-step explanation:

Given:

Service Fee= $22

Fixed rate per gallon= m

Water Consumed= 2256 gallons

Total bill charged= $31.02

Now by computing the equation we get

\textrm{Total bill charged} = \textrm{Service fee} + (\textrm{fixed charge per gallon} \times \textrm{water consumed})

Substituting data we get

22+m2256=31.02

m2256= 31.02-22

m2256=9.02

\therefore m =\frac{9.02}{2256} =0.00399

Rounding off above value we get

m=0.004 per gallon

A catapult launches a boulder with an upward velocity of 92 m/s. the height of the boulder, h, in meters after t seconds is give
omeli [17]
Check the picture below.

\bf \textit{vertex of a vertical parabola, using coefficients}
\\\\
h=\stackrel{\stackrel{a}{\downarrow }}{-5}t^2\stackrel{\stackrel{b}{\downarrow }}{+92}t\stackrel{\stackrel{c}{\downarrow }}{+16}
\qquad \qquad 
\left(-\cfrac{ b}{2 a}~~~~ ,~~~~  c-\cfrac{ b^2}{4 a}\right)

\bf \left( -\cfrac{92}{2(-5)}~~,~~16-\cfrac{92^2}{4(-5)} \right)\implies \left(\cfrac{46}{5}~~,~~16+\cfrac{2116}{5}  \right)
\\\\\\
\left(\cfrac{46}{5}~~,~~\cfrac{2196}{5}  \right)\implies \left(\stackrel{\textit{how long it took}}{9\frac{1}{5}}~~,~~\stackrel{\textit{how high it went}}{439\frac{1}{5}}  \right)

Danny wants to buy a truck in 4 years. He is going to put away $2,500.00 into his savings account that will pay him 6.75% intere
aniked [119]

Answer:

b $3,272.43

Step-by-step explanation:

A = p(1+r/n)^nt

Where

A= future value

P= principal = $2500

r= interest rate = 6.75% = 0.0675

n = number of periods = 12

t = time = 4 years

A = p(1+r/n)^nt

= 2500(1+0.0675/12)^12*4

= 2500(1+0.005625)^48

= 2500(1.005625)^48

= 2500(1.3089737859257)

= 3272.4344648144

Approximately

A= $3272.43

He will have $3272.43 to give as down payment in 4 years
