You plan to construct a brick wall measuring 14.5 ft. in length, 5.5 ft. high, and 0.5 ft. in width. If a brick measures 6 in. x
Licemer1 [7]

Answer: There are 1436 bricks that he will need to make a brick wall.

Step-by-step explanation:

Since we have given that

Dimensions of a brick wall is given by

Length = 14.5 feet

Width = 0.5 feet

Height = 5.5 feet

Dimensions of a brick is given by

Length = 6 inch

Width = 4 inch

Height = 2 inch

We need to find the number of bricks :

So, Number of bricks is given by

\text{ Number of bricks }=\frac{\text{ Volume of brick wall }}{\text{ Volume of brick}}\\\\=\frac{14.5\times 5.5\times 0.5\times 12\times 12\times 12}{6\times 4\times 2}\\\\=1435.5\\\\=1436

Hence, there are 1436 bricks that he will need to make a brick wall.

Orlando is doing a math problem where he needs to dilate a triangle by a scale factor of four. The ordered pairs for his pre-ima
Rainbow [258]
Dilation refers to a non rigid motion where a figure is transform and its image has the same form but a different size measure.
Dilation is define by the rule (x,y)-- (kx, ky) where k represents the scale factor.

On this exercise is given that a triangle with vertices (-2,1), (8,4), and (3,0) was dilated by a scale factor of four, and it is asked to find the vertices of the image of the triangle after the dilation occurred.

Pre-image                       Image
(-2,1)  --   (-2*4,1*4)   --   (-8,4)
(8,4)   --    (8*4,4*4)   --    (32,16)
(3,0)   --    (3*4,0*4)   --    (12,0)

The coordinates representing the vertices of the triangle's image are (-8,4), (32,16), and (12,0); meaning that the ordered pair which is not a coordinate for a point in the triangle's image is (2,1).
