Answer:

1. 10

2. 12

3. Sqrt 130

4. Sqrt 45

Step-by-step explanation:

To find the missing side of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem is $a^2+b^2=c^2$ where a and b are the legs with a being the smallest and c is the hypotenuse.

1. a=6, b=8, c=?

$6^2+8^2=c^2\\36+64=c^2\\100=c^2\\10=c$

2. a=5, b=?, c=13

$5^2+b^2=13^2\\25+b^2=169\\169-25=b^2\\144=b^2\\12=b$

3. a=7, b=9, c=?

$7^2+9^2=c^2\\49+81=c^2\\130=c^2\\\sqrt{130}=c$

4. a=2, b=?, c=7

$2^2+b^2=7^2\\4+b^2=49\\49-4=b^2\\45=b^2\\\sqrt{45}=b$

422 8/100 fraction notation

Ivenika [448]

The rule to convert a mixed fraction to an improper fraction is

$a\frac{b}{c} =\frac{(a)(c)+b}{c}$

Here in $422\frac{8}{100}$

Here a = 422, b = 8 and c = 100

Now a × c = 422 × 100 = 42200

And 42200 + 8 = 42208

So we have

$422\frac{8}{100} =\frac{(422)(100)+8}{10}=\frac{42200+8}{100}=\frac{42208}{100}$

This fraction can also be reduced as

$\frac{42208}{100}=\frac{10552}{25}$

Hence

$422\frac{8}{100}=\frac{42208}{100}=\frac{10552}{25}$

Math word problem,<br> thank you

Answer:

$81.92

Step-by-step explanation:

Week 1:

250 * 20% = 50

250 - 50 = 200

Week 2:

200 * 20% = 40

200 - 40 = 160

Week 3:

160 * 20% = 32

160 - 32 = 128

Week 4:

128 * 20% = 25.6

128 - 25.6 = 102.4

Week 5:

102.4 * 20% = 20.48

102.4 - 20.48 = 81.92
