Answer:
Do I really need it?
Can I find it for a cheaper price?
Can I replace it with something else that I already have or that has a lower price?
Step-by-step explanation:
When you are trying to build up your savings you need to to spent money only on the necessary things to be able to save more money every time you get paid. So, according to this, the three questions that Aria should ask herself before making a purchase are:
-Do I really need it? To make sure that it is something that you really require and not something that you just want to buy but it is not going to cover a need.
-Can I find it for a cheaper price? Maybe you can buy it in another place where the product has a lower price or you can get a cheaper brand.
-Can I replace it with something else that I already have or that has a lower price? Maybe you already have a product that does the same thing or you can buy one that replaces the function this one does and that is cheaper.
5 is a prime factor of 155. Dividing 155 by 5, we get 31. 1*5*31 = 155.
Answer: 2 < x < 16
The triangle inequality theorem says that if we have a triangle with sides a,b,c then
b-a < c < b+a
with b being longer than 'a'
In this case, a = 7 and b = 9 and c = x
so we have
b-a < c < b+a
9-7 < c < 9+7 .... replace a with 7, replace b with 9
2 < c < 16
2 < x < 16 .... replace c with x
So x can be any number between 2 and 16. The value of x cannot be equal to 2. Also, x cannot be equal to 16 either.
The right answer for the question that is being asked and shown above is that: "13 ft."An iron tank is constructed in the form of an isosceles trapezoid. Each base angle measures 105°, the length of the base is 10 feet, and each of the <span>nonparallel sides is 12 feet long. The length of a diagonal brace to the nearest whole number is 13 ft</span>
Answer:
B
Step-by-step explanation:
Since the cones are similar then the ratio of corresponding sides are equal, that is
= 
( h is the height of the smaller cone )
Cross- multiply
18h = 540 ( divide both sides by 18 )
h = 30 cm → B
