D. 304 sq units

Surface area is just finding the area of each face of a 3d figure and adding it up together:

Area of square base:
8 • 8 = 64 sq units

Area of ONE triangle face:
1/2 • 15 • 8 = 60 sq units
MULTIPLY that by 4 because we have 4 triangle faces: 60 • 4 = 240 sq units

ADD area of square base and 4 triangle faces: 240 + 64 = 304

FINAL ANSWER OF SURFACE AREA:
304 sq. units

BRAINLIEST will be much appreciated!

What are the coordinates of the y-intercept of the line who's equation is 12x + 13y =8???
Ierofanga [76]

Answer:

y-intercept = (0,  \frac{8}{13} ).

Step-by-step explanation:

Given the linear equation in standard form, 12x + 13y = 8:

We must transform this equation into slope-intercept form to make it easier to determine the coordinates of the y-intercept.

12x + 13y = 8

Subtract 12x from both sides:

12x + 13y - 12x = - 12x + 8

13y = - 12x + 8

Next, divide both sides of the equation by 13 to solve for y:

\frac{13y}{13} = \frac{-12x + 8}{13}

y = \frac{-12x + 8}{13} or  y = -\frac{12}{13} x + \frac{8}{13}

Next, to determine the y-intercept, we must set x = 0 (because the y-intercept is  the point where the graph of the linear equation crosses the y-axis).

Let x = 0:

y = -\frac{12}{13} x + \frac{8}{13}

y = -\frac{12}{13} (0) + \frac{8}{13}

y = \frac{8}{13}

Therefore, the value of y when x = 0 is \frac{8}{13} . This is the y-intercept, and its coordinate is (0,  \frac{8}{13} ).

Answer:

17 512 dm3    27 28 dm3  37 43 dm3 47 52 92 cm3    57 42  m3

Step-by-step explanation:

17 volume= 8x8x8= 512 dm3

27 volume= 3.5x4x2= 28m3

37 volume= 4x2, 5x4.3= 43 dm3

47 volume= 18x14x21= 5292 cm3

57 volume= 4x3x3.5= 42 m3

the volume cuboid = length x width  x height )
