A rectangular prism has a length of 7 cm, a width of 4 cm, and a height of 2 1/2cm. The prism is filled with cubes that have edge lengths of cm. How many cubes are needed to fill the rectangular prism? (I got 140, but I dunno if that's right)​

there are 54 cubes in a rectangular prisum

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
