Please help asap! will mark brainliest if correct! if not, no brainliest.

the answer is 147 yd^3

Step-by-step explanation:

this is becuase the formula for calculating volume of a pyramid is 1/3lwh, where l is length, w is width, and h is height. plug in the values shown in the picture, and you would get 1/3(7)(9)(7). that expression is equal to 147. hope it helps

1.true 2.false? ? i think. .

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
