8 0

Answer: the first equation is the answer.

Step-by-step explanation: As you can see the first equation is 5/7=15/21. The are proportional because 5*3=15 and 7*3=21. If they are multiplied or divided by the same number, then they are proportional. It does not work with adding, subtracting or flipping.

Answer: 3/4 inch

Step-by-step explanation:

When Jim was 15, he grew 1/4 of an inch and when he was 16, he grew 1/2 of an inch.

Senior : 5.75 * 2006 =   11,534.50

What’s the answer?.....
vitfil [10]

Answer:

B

Step-by-step explanation:

The triangle UVW is similar (or congruent) to the triangle XZY.

U angle of the triangle UVW = 36 degrees

X angle = 180 - 72 - 72 = 36 degrees

Therefore:

V angle = Z angle = 72 degrees

W angle = Y angle = 72 degrees

Triangle UVW is a isosceles triangle at angle U.

=> UV = UW = 5.7 cm

=> the perimeter of triangle UVW = the perimeter of triangle XZY = 5.7 x 2 + 3.7 = 15.1 cm
