Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle add up to 
. Therefore, an equiangular triangle will have each of its angles equal to 
. We can then set up the following equation:
.
Answer:
About 4 minutes and 3 seconds
Step-by-step explanation:
If I have 55 invitations to be created in four hours.
4 hours × 60 =240 minutes
240/55= 4.36 minutes
So if I spend 4 minutes and 3 seconds on an invitation, I should be able to fill the order.
Answer:
3 a : 2 b = 6 : 1
Step-by-step explanation:
<em>
= 
</em>
<em>3 ( a + b) = 5 ( a - b)
</em>
<em>3 a + 3 b = 5 a - 5 b
</em>
<em>5 b + 3 b = 5 a - 3 a
</em>
<em>
8 b = 2 a
</em>
<em>
2 a = 8 b</em>
<em><u>a = 4 b</u></em>
<em>3 a = 3 × 4 b</em>
<em><u>3 a = 12 b</u></em>
<em>3 a: 2 b = 12 b : 2 b</em>
<em>3 a : 2 b = 6 : 1</em>
Answer:
Cornel pays $44.75 for his video game.
Step-by-step explanation:
First, you have to find the price after the 25% discount by calculating 25% of the initial price and subtracting that result from the original price:
60*25%=15
60-15=45
Then, you have to find the price after the 12% discount by calculating 12% of the price after the 25% discount and subtracting that result from the price after the 25% discount:
45*12%=5.4
45-5.4=39.6
Finally, you have to find the price including the tax by calculating 13% of the price after the discounts and add the result to that price:
39.6*13%=5.15
39.6+5.15=44.75
According to this, Cornel pays $44.75 for his video game.
a) 2 + 3 - 6 = 10 + 4 ⇒ -1 = 14
This is a false statement so it has NO SOLUTIONS, which means it is a CONTRADICTION
b) 17 + 5 = 23 + 4 - 6 ⇒ 25 = 21
This is a false statement so it has NO SOLUTIONS, which means it is a CONTRADICTION
c) 7 + 4 = 5 + 8 + 2 - 10 ⇒ 11 = 5
This is a false statement so it so it has NO SOLUTIONS, which means it is a CONTRADICTION
NOTE: When they make a true statement, then it has infinite solutions and is an Identity
