A homeowner has two different sets of triangular tiles, green tiles and blue tiles. Which of these would prove that the green and blue tiles are congruent
Answers
Answer: Determining if the two longest sides of each color tile plus either pairs of corresponding sides are congruent.
Step-by-step explanation:
Its a multi question but read and you'll be able to pinpoint the correct answer.
Determining all three pairs of corresponding sides of green and blue tiles are congruent is correct congruence criteria. The third option is correct.
What is congruent?In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.
Given:
A homeowner has two different sets of triangular tiles, green tiles and blue tiles.
Third choice shows that two triangles are similar.
If the three pairs of green and blue tiles with corresponding sides match.
The triangles are therefore said to be congruent according to the SSS (Side-Side-Side) Criteria.
No alternative choice satisfies any of the congruence requirements. Because there are two sides, we also require the angle between them to be congruent.
When both of the triangles have a right angle, the longest side congruence is taken into account.
Therefore, the third option is correct.

Multiplying by 0.23 is the same as decreasing by _____%
Answers
ANSWER:
"Multiplying by 0.23 is the same as decreasing by 23%"
EXPLANATION:
It is the same as decreasing by 23% because when converting from percentage to decimal, it's 1% is 0.01.
You may also determine this too by knowing that 1% of 100 is 1. But, multiplying 0.01 by 100 is the same.
It is not 77% however, as you are not decreasing that number by another number.

The weekly earnings of students in one age group are normally distributed with a standard deviation of $110. A researcher wishes to estimate the mean weekly earnings of students in this age group. Find the sample size needed to assure with 99 percent confidence that the sample mean will not differ from the population mean by more than $10.
Answers
Answer: 806
Step-by-step explanation:
Given that:
Standard deviation (s) = $110
Error = $10
Zcritical ; Zα/2 at 99% confidence interval = 2.58
Using the relation :
[(Zα/2 * s) / sqrt(n)] < 10
[(2.58 * 110) /sqrt(n)] = 10
283.8 / sqrt(n) = 10
283.8 = 10 * sqrt(n)
Sqrt(n) = 283.8/ 10
Sqrt(n) = 28.38
Square both sides
n = 28.38^2
n = 805.4244
n = 806
Hence, sample size = 806

Last week you earned $500 at work and decided you want to invest it in a high rate high stakes investment account. The account earns 11% interest and is compounded daily. How long will you have to leave the money in the account to have $650?
Answers
Answer:
t = 2.4 years
Step-by-step explanation:
t = log(A/P) / n[log(1 + r/n)]
A = future earnings = $650
P = principal = $500
r = interest rate = 11%
n = 365
t = ? Years
t = log(A/P) / n[log(1 + r/n)]
= log (650/500) / 365{log(1 + 0.11/365)}
= log(1.3) / 365{log(1 + 0.00030)}
= 0.1139 / 365{log(1.00030)}
= 0.1139 / 365(0.00013)
= 0.1139 / 0.04745
= 2.4
t = 2.4 years
what is the arc length of a semicircle with diameter of 8
Answers
Answer:
25.13 or so.
Step-by-step explanation:
You find the circumference, which is about 50.27, I think. Since it's a semicircle and thus half the circle, the part of the total circumference that's still in the semicircle will be half of the actual circumference. This means it should be about 25.13, I think.

C. The consultant charges $275 per hour.
D. The consultant's hourly
Answers
Answer:
B
Step-by-step explanation:
The variable "h" stands for hours worked, and it is next to the 125 because the value will change at an hourly rate. The 150 will always be constant in this equation so it's clear that it is the constant fee.
