Answer:

$7 \frac{23}{40}$

Step-by-step explanation:

2 and 1/4 + 2 and 1/5 + 3 and 5/8

$= 2 \frac{1}{4} + 2 \frac{1}{5} + 3 \frac{1}{8} \\ \\ = \frac{2 \times 4 + 1}{4} + \frac{2 \times 5 + 1}{5} + \frac{3 \times 8 + 1}{8} \\ \\ = \frac{8 + 1}{4} + \frac{10 + 1}{5} + \frac{24 + 1}{8} \\ \\ = \frac{9}{4} + \frac{11}{5} + \frac{25}{8} \\\\(lcm \: of \: 4, \: 5, \: 8 \: = 40) \\ \\ = \frac{9 \times 10}{4 \times 10} + \frac{11 \times 8}{5 \times 8} + \frac{25 \times 5}{8 \times 5} \\ \\ = \frac{90}{40} + \frac{88}{40} + \frac{125}{40} \\ \\ = \frac{90 + 88 + 125}{40} \\ \\ = \frac{303}{40} \\ \\ = 7 \frac{23}{40}$

A circle with center (-3,5) passes through point (-9,-3). Find the circumference of the circle

Aliun [14]

Answer:20π

Step-by-step explanation:

equation of the circle

(x+3)² + (y-5)² = r²

now, (-9, -3) lies on it

So, (-9+3)² + (-3-5)² =r²

36+ 64 = r² =100

hence, r =10

So, circumference = 2πr = 20π
