Answer:

see explanation

Step-by-step explanation:

Since figure B is smaller than Figure A then Figure B is a reduction.

To find the scale factor, calculate the ratio of corresponding sides, image to original.

Using the base lines of both triangles, then

scale factor k = $\frac{2}{6}$ = $\frac{1}{3}$

Help solve for r????

Aleonysh [2.5K]

$\ \frac{66(r)}{22} - ( \frac{16}{16} - 1) = r + \frac{72}{3} \div 3 \\ \frac{3r}{1} - 0 = r + 72 \\ 3r = r + 72 \\ r = 36$

Judy is now twice as old as Adam, but 6 years ago, she was 5 times as old as he was. How old is Judy now?

qaws [65]

Answer:

Judy is 16 years old

Step-by-step explanation:

J = Judy's age

A = Adams age

J = 2A

Six years ago (subtract 6 from the ages)

(J-6) = 5*(A-6)

Distribute

J-6 = 5A - 30

Substitute J = 2A

2A -6 = 5A -30

Subtract 2A from both sides

2A-2A -6 = 5A-2A -30

-6 = 3A -30

Add 30 to each side

-6+30 = 3A-30+30

24 = 3A

Divide by 3

24/3 = 3A/3

8 = A

Adam is 8 years old now

We need to find Judy's age

J = 2A

J = 2*8

J = 16

Judy is 16 years old

Find the area of the triangle.<br><br> Be sure to label your answer. Round to the nearest hundredth.

olga2289 [7]

Your answer would be 31.5 (so 32 when rounded up)

For triangles you basically multiply them together, and the divide your answer by two.

A= 1/2 b x h
A= 1/2 7 x 9
A= 1/2 63
A= 31.5 (rounded up to 32)

I hope I helped and if you need more you could always ask me :)
