The area of the front side of the toy building is 1 square foot. The real building's

1 answer:

6 0

The ratio or the relationship of the toy to the large building is one foot to every 400 feet so in mathematical terms it’s shown as a ratio like this... 400:1 and since they are asking about the real building as the primary reason for the ratio it’s number goes first because they are enquiring about it’s relationship to the small one.(which is worded weirdly so I think they are trying to get you messed up)
Good luck

Prove that the quadrilateral whose vertices are I(-2,3), J(2,6), K(7,6), and L(3, 3) is a rhombus.

I think in these problems the first step is to express each side as a vector. A vector is the difference between points. When two sides have the same vector (or negatives) it means they're parallel and congruent. So in a rhombus IJKL the vectors IJ and LK should be the same, as should JK and IL. That much assures a parallelogram; we check IJ and JK are congruent to complete the crowing of the rhombus.

Let's calculate these vectors:

IJ = J - I = (2,6) - (-2,3) = (2 - -2, 6 - 3) = (4, 3)

LK = K - L = (7, 6) - (3, 3) = (4, 3)

IJ = LK, so far so good

(Note: If you haven't got to vectors yet you can just show the two sides are the same length, 5, and have the same slope, 3/4, both of which can be read off the vectors.)

JK = K - J = (7,6) - (2,6) = (5,0)

IL = L - I = (3, 3) - (-2, 3) = (5, 0)

Those are the same too.

Now we have to show IJ ≅ JK

The length of IJ is the cliche √4²+3² = 5, the same as JK, so IJ ≅ JK

We showed all four sides are congruent and we have two pair of parallel sides, so we have a rhombus.

Y=x+4 Y=2x+6 Solve for x and y

gladu [14]

Answer:

X = -2

y = 2

Step-by-step explanation:

Substitute y=x + 4 in the second equation to find x

x+4 = 2x + 6

subtract x from both sides

4 = x + 6

subtract 6 from both sides

-2 = x

put -2 in for x in the first equation

y= 2
