You could either find how far Chris can run in 60 minutes, or write an equation of ratios:

    x            35 min
--------- = --------------
 6 mi          50 min

Solving for x:  50x = 210;     x = 4.2 miles (answer)

Given: rectangle ABCD is similar to rectangle ZBXY. If ZY = 5, XC = 3, DC = 4, then XY =
soldier1979 [14.2K]

Answer:

The length of XY is either 10 or 2.5.

Step-by-step explanation:

Given information: ZY = 5, XC = 3 and DC = 4.

Case 1: Rectangle ABCD is smaller than ZBXY.

The opposite sides of the rectangle are same.

ZY=BC+XC

5=BC+3

2=BC

The length of ABCD is 4 and width of ABCD is 2. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.

\frac{4}{XY}=\frac{2}{5}

\frac{4\times 5}{2}=XY

10=XY

Therefore the value of XY is 10.

Case 2: Rectangle ABCD is larger than ZBXY.

ZY=BC-XC

5=BC-3

8=BC

The length of ABCD is 4 and width of ABCD is 8. The width of ZBXY is 5. The corresponding sides of the similar rectangles are is in the same proportion.

\frac{4}{XY}=\frac{8}{5}

\frac{4\times 5}{8}=XY

2.5=XY

Therefore the value of XY is 2.5.

To solve this, you need to plug in the numbers for <em>h</em>.

-4(-12) ≥ 8       48 ≥ 8  yes

-4(-7) ≥ 8         28 ≥ 8  yes

-4(-5) ≥ 8        20 ≥ 8  yes

-4(-3) ≥ 8        12 ≥ 8  yes

-4(-2) ≥ 8         8 ≥ 8  yes

-4(-1) ≥ 8         4 ≥ 8  no

-4(1) ≥ 8          -4 ≥ 8  no

-4(3) ≥ 8         -12 ≥ 8 no

-4(8) ≥ 8         -32 ≥ 8  no

Hope this helped!

<span>The probability of missing the first shot is 40%. When she misses the first shot, the probability of missing the second shot is very, very low, only 5%. That means that the probability of missing both shots must be much smaller than the probability of missing the first shot.
