With this one, since the problem says it will cost $35 per hour, then that will be based on the amount of hours spent on the job, so 35 gets the x, with x equaling the number of hours it took to do the job.  $78 is the cost for a part so it is going to stay at 78.  So your answer will be D.  35x+78≤225.

A fish tank has the shape of a rectangular prism. It has a length of 214 m, width of 78 m, and a height of 112 m.
siniylev [52]
To find the volume you have to multiply the length width and height.

Your answer would be 1869504 which is not one of your choices though.

Can you double check you choices?

Write area f a circle as a function of circumfrence
Y_Kistochka [10]

circumference = 2\pi  \times r
area = \pi {r}^{2}
we want area =circumference*something
dividing our first equation by 2*pi
\frac{circumference}{2\pi}  = r
substituting in the second equation
area = \pi { (\frac{circumference}{2\pi}) }^{2}
simplifying
area = \pi(\frac{ {circumference}^{2} }{4 {\pi}^{2} } )
area =  \frac{{circumference} ^{2} }{4\pi}

Look at the graph of a line and write its equation​
Mice21 [21]

Answer:

y=-2/3x-1

Step-by-step explanation:

You can fins the slope (or the m in y=mx+b) by counting how many units up/down and over it takes to get to another solid point and configuring it into a fraction rise/run. in this case you go down 2 units and over 3 units to get -2/3

to get the y-intercept (the b in y=mx+b) you look at where the lince intercepts the y-axis in this case it is at -1
