Describe the differences that exist between the informal geometric reasoning and formal thinking used to prove conjectures
Answer:
hey
Step-by-step explanation:
Formal geometric reasoning gives better information than informal geometric reasoning.
What is informal geometry?Informal Geometry is defined as the aid for understanding geometry via questioning, practices, and conjecture. Subjects include stature, balance, isometries, and proportions, with scaling as a major theme.
What is formal geometric?Formal geometry is defined as geometric explanations that are ways to formally make an opinion about a particular formation or figures in the geometrical entity, a formal geometric explanation is a detailed way to deliver that specific figures or domains which are congruent.
An an conjecture is made often using observation and detail given on the basis of logical observation is termed informal geometric reasoning,
While in formal geometric reading calculation-based approximation conjectures gives better detail of the informal geometric reasoning.

Step-by-step explanation:
The absolute value of a number is its distance from 0. This means a number would be itself if it was positive and if it was negative it would be its opposite. Since 985 is positive, |985| would just be 985.

congrats? Im not sure what to say.
An unknown metal having a mass of 287.8 g was added to a graduated cylinder that contained
31.47 mL of water. After the addition of the metal, the water level rose to 58.85 mL. Determine
the volume of the metal. Calculate the density of the metal using dimensional analysis.
The metal displaced a volume of
58.85 mL - 31.47 mL = 27.38 mL = 27.38 cm³
of water, which is to say the metal has this volume.
If the metal has a mass of 287.8 g, then its density is its mass per unit volume,
(287.8 g)/(27.38 cm³) ≈ 10.51 g/cm³

Answer:
(a) $3.00
(b)(i) $33.00
(b)(ii) $322.50
Step-by-step explanation:
(a)
100% = $20.00
1% = 100%/100 = 20/100 = $0.20
15% = 1%×15 = 0.2×15 = $3.00
so, he actually has to pay $20 + $3 = $23 per toaster.
or shorter and direct, since we calculate the extra 15% based on the original 100%, we can say he has to pay 115% of the basic price.
115% = 0.2×115 or = 100%×1.15 = 20×1.15
0.2 × 115 = $23
20 × 1.15 = $23
so, you can see the several ways to get to the result.
in any case, the profit is $26-$23 = $3 per toaster.
(b)(i)
100% new price = 100% old price + 20% = 120% old price
or 100% old price × 1.2
100% new price per toaster = 20×1.2 = $24.00
the new tax is increased TO 25% (not by 25%) be careful to see that detail.
so, we need to add 25% of the new price.
125% new price = 24×1.25 = $30.00
so, in order to make again $3 profit, the customer has to pay now $30+$3 = $33.00
(b)(ii)
100% (b)(i) selling price = $33.00
30% more means 130% of that, or 1.3×100%
33×1.3 = $42.90
so, the profit per toaster is now 42.90 - 30 = $12.90
when selling 25 of these toasters the profit is then
25×12.90 = $322.50

Unit 1 : Algebra basics Homework 1: the real numbers
Real numbers may be explained as all set of numbers which may be used for counting, fractions or decimals. Real numbers may be any set of natural, whole, integer, rational or irrational numbers.
• NATURAL NUMBERS which are all set of positive whole numbers from 1. Examples : (1, 3, 5, 8, 100)
• WHOLE NUMBER are set of all natural numbers .while numbers also include the value value (0, 1, 200, 500) are whole numbers
• INTEGERS : include all positive and negative natural or whole number values. They include (-1, - 10, 10, 5)
• RATIONAL numbers are real numbers which can be expressed in the form m/n where both m and n are integer values and the denominator, n ≠ 0 Examples : (1/2, 0.9, 10/1, √4, 3.5)
• IRRATIONAL numbers are real numbers which are not integer values and cannot be expressed in the form m/n Non-terminating and non-repeating decimal numbers are IRRATIONAL numbers. (√3, 1.43136..., 1.4141..., π)

how much would $500 invested at 5% interest compounded continuously be worth after 8 years?
a: $700
b:$709.58
c:$745.88
d.$738.73
Answer:
D
Step-by-step explanation:
We will need to use the compound interest formula:
A = P(1 + r)ⁿ
A = final amount
P = Initial amount
r = rate
n = time applied
Our equation will then look like this
A = 500(1.05)⁸
A = 738.72772

Step-by-step explanation:
The PTA sells 100 tickets for a raffle and puts them in a bowl. They will randomly pull out a ticket for the first prize and then another ticket for the second prize. You have 10 tickets and your friend has 10 tickets. What is the probability that your friend wins the first prize and you win the second prize?
0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.
-----------------------------------
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
Event A: Your friend wins the first prize.
Event B: You win the second prize.
-----------------------------------
Probability friend wins first prize:
10 out of 100 tickets, so:
[tex]P(A) = \frac{10}{100}[/tex]
-----------------------------------
Probability you win second prize:
There will be 99 tickets remaining(1 has been sorted), you have then of then, so:
[tex]P(B) = \frac{10}{99}[/tex]
-----------------------------------
What is the probability that your friend wins the first prize and you win the second prize?
Multiplication of the probabilities, thus:
[tex]p = P(A) \times P(B) = \frac{10}{100} \times \frac{10}{99} = \frac{10\times10}{100\times99} = 0.0101[/tex]
0.0101 = 1.01% probability that your friend wins the first prize and you win the second prize.
