Two squares always, sometimes ,or never similar ? explain

1 answer:

3 0

Two squares is sometimes similar.

A square can be any size, as long as all four of it's sides are equal.
A square would be a rectangle if two of the sides were different than the rest.
A square would be a trapezoid if only one of it's sides were different.

For a square to be always similar, the ratio of it's sides must be equal to the ratio of the second square.

For example:

All of a square's sides are 5 across.
In order for another square to be ALWAYS similar, it's sides must be a multiple of (The length of the original square's sides) 5 (10,15,20,25,30...)

This is called a ratio. (5/10 = 1/2, 5/15 = 1/3, 5/20 = 1/4 etc...)

SVETLANKA909090 [29]

Answer: The required probability is 0.1923.

Step-by-step explanation:

Since we have given that

Probability that it's a good dog = 0.4

Probability that it's a bad dog = 1-0.4 = 0.6

Probability that the dog smokes given that its a bad dog = 0.7

Probability that it smokes given that its a good dog = 0.25

According to question, probability of smoking pipe would be

P(good).P(Smoking pipe|good)+P(bad).P(smoking pipe|bad)

$0.4\times 0.25+0.6\times 0.7\\\\=0.1+0.42\\\\=0.52$

So, Probability of getting a good dog given that it is smoking pipe is given by

$\dfrac{P(good).P(smoking\ pipe|good)}{P(smoking\ pipe)}\\\\=\dfrac{0.4\times 0.25}{0.52}\\\\=\dfrac{0.1}{0.52}\\\\=0.1923$

Hence, the required probability is 0.1923.

How much does 2.5 L of oil cost if 2,000 mL costs $5.00?<br> Show work

kkurt [141]

Answer:

$6.25

Step-by-step explanation:

2000ml = 2 litres

2.5L - 2L = 500ml

So now we know that without the 500ml, it is 5 dollars.

Find out how much 500 ml cost.

2000ml = 5.00

1ml = 5.00 ÷ 2000 = 0.0025

500ml = 0.0025 x 500 = 1.25

2L + 500 ml = 2.5L (which 2.5L costs 6.25)

Temka [501]

Given:

Jason buys three shirts with a listed price of $20 each.

He uses a coupon that provides "Buy Two, Get One Free".

To find:

The total final price Jason pays.

Solution:

Total number of shirts he buys = 3

Since he uses a coupon that provides "Buy Two, Get One Free", therefore he need to pay for 2 shirts and 1 he will get free.

Cost of 1 shirt = $20

Cost of 2 shirts = 2 × $20

= $40

Therefore, total final price Jason pays is $40.
