Answer:

Yes

Step-by-step explanation:

using pythagorus theorum: a^{2} + b^{2} = c^{2}

24^{2} +32^{2} = 1024+576

= 1600

40^{2} = 1600

thus, it can be concluded that these lengths can be the sides of a right-angled triangle.

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 13 of one section of the fence.

Question:

You have a 32-foot fence around a square garden. There are 4 equal sections. You paint 1/3 of one section of the fence. What fraction of the fence did you paint?

Answer:

The fraction of the fence painted is $\frac{1}{12}$

Solution:

Given that:

You have a 32-foot fence around a square garden. There are 4 equal sections

Find the length of each section:

4 sections = 32 foot

$\text{ 1 section } = 32 \div 4 = 8 foot$

Find the length that is painted:

$\text{ Fence painted }= \frac{1}{3} \text{ of one section }\\\\\text{ Fence painted }= \frac{1}{3} \times 8 = \frac{8}{3} \text{ foot }$

Therefore $\frac{8}{3}$ foot of fence is painted

Find the fraction that that is painted:

Total length of fence = 32

$\text{ Fraction of the fence painted } = \frac{8}{3} \div 32 = \frac{8}{3} \times \frac{1}{32}\\\\\text{ Fraction of the fence painted } = \frac{1}{12}$

Therefore $\frac{1}{12}$ fraction of the fence is painted

A jar of marbles contains 5 blue 12 red, and 8 yellow marbles. what is is probability that you you select a blue marble, keep it

ruslelena [56]

5+7+8= 20

5/20

20-1= 19

8/19 (becomes 19 because you are not replacing the marble)
