8 0

Answer:

270 first question's answer

Step-by-step explanation:

Solution at attachment box

Total surface area of cuboid is = 12x18x2 + 10x12x2 +18x10x2

=432+240+360

=1032

Surface of the 1 cube =2x2x2 = 8

Surface of the all cubes = 8x270 = 2160

B) Find the value of x. Show algebraic support.<br> hint: sum of the exterior angles is 360
schepotkina [342]

Answer:

x = 16

Step-by-step explanation:

Given that the sum of the exterior angles is 360°

Sum the given exterior angles and equate to 360

47 + 93 + 46 + 3x + 62 + 4x = 360, that is

248 + 7x = 360 ( subtract 248 from both sides )

7x = 112 ( divide both sides by 7 )

x = 16

find point p that divides segment AB into a 2:3 ratio. The point should be closer to A. A(-3,1) and B(3,5)
Mademuasel [1]
First, work out how much you need to add to A's x and y coordinates in order to get to point B from point A.

So (using Ax to mean x-coordinate of A, Ay the y-coordinate of A, etc):
x-difference = Bx - Ax = 3 - (-3) = 3 + 3 = 6
y-difference = By - Ay = 5 - 1 = 4

Now, if the point divides the segment AB in the ratio 2:3, then it is 2/(2+3) of the way along the line AB.

i.e. it is 2/5 of the way along the line AB.

We therefore need to add 2/5 of the x- and y-differences to point A to get point p:
px = Ax + (2/5)*(x-difference) = -3 + (2/5)*6 = -3 + 12/5 = -15/5 + 12/5 = -3/5 = -0.6
py = Ay + (2/5)*(y-difference) = 1 + (2/5)*4 = 1 + 8/5 = 5/5 + 8/5 = 13/5 = 2.6

Therefore coordinates of p are (-0.6, 2.6)
