Please help me! :)
Eva8 [605]

y = - \frac{4}{3} x - 3

the equation of a line in ' slope intercept form ' is

y = mx + c

where m is the slope and c the y-intercept

here m = - \frac{4}{3} and c = - 3

thus y = -  \frac{4}{3}  x - 3 is the slope- intercept equation

The dimensions of a storage container in the shape of a rectangular prism are 54 in x 32.25 in x 24.5 in. Choose True or False f
AlladinOne [14]

GIVEN

the dimensions ofrectangular prism are

length = 54 in

breadth = 32.25in

height = 24.5 in

formula

volume of the rectangular prism = length×breadth×height

                                                   = 54 ×32.25×24.5

                                                   = 42997.5 in³

first statement is false because the volume of the rectangular prism in two significant digit.

Second statement is false because the volume of the rectangular prism in two significant digit.

FORMULA

surface area of a rectangular prism = 2(wl+hl+hw)

by putting the value of the length , breadth & height

we get

= 2 (54×32.25 + 32.25×24.5 + 24.5×54)

= 7709.25 in²

= 7709.3 in²(approx)

Third statement is true the surface area of the container is rounded  to ones place.

Hence proved
