Suppose △ITH≅△APG.
Which congruency statement is true?
Answers
answer
B. IH = AG
It is given that the triangles ITH and APG are congruent.
When the two triangles are congruent, then the corresponding angles and sides are congruent to each other.
By being congruent, the corresponding angles which are congruent are:
[tex]IT \cong AP, TH \cong PG, IH \cong AG[/tex]

Answers
4sinθ + 3√3 = √3
First subtract 3√3 from both sides:
4sinθ = -2√3
Now, divide by 4:
sinθ = (-2√3)/4

Using the unit circle we know that sin of -√3/2 is 240° or 4/3π and 300° or 5/3π

Answers
Answer: Simplifying the expression of the substraction of the two complex numbers we get 11-2i
Solution:
(5-5i)-(-6-3i)
Eliminating the parentheses: 5-5i+6+3i
Grouping similar terms: (5+6)+(-5+3)i
Adding the similar terms: 11+(-2)i = 11-2i
Answer:
The simplify form of given expression is 11-2i.
Step-by-step explanation:
The given expression is
[tex](5-5i)-(-6-3i)[/tex]
Using distributive property, we get
[tex]5-5i-(-6)-(-3i)[/tex]
[tex]5-5i+6+3i[/tex]
Combined real and imaginary parts.
[tex](5+6)+(-5i+3i)[/tex]
[tex]11+(-2i)[/tex]

Therefore the simplify form of given expression is 11-2i.
Reese spent $4.95 on cookie supplies. He sold 24 cookies at $2 each. His profit is how much more he got from selling the cookies than he spent. What was his profit?
Answers
To solve this problem, we should first find out how much Reese made from selling cookies. To do this, we have to multiply the cost of one cookie ($2) by the number of cookies he sold (24). This is modeled below:
24 * $2 = $48
To find Reese's total profit, we must subtract how much he spent on the supplies ($4.95) from his earnings ($48). This is modeled below:
$48 - $4.95 = $43.05
Therefore, Reese's profit is $43.05.

If a and b are any two real numbers, explain how you calculate the difference a - b. Be sure to include the following in your explanation.
(A) a description of the relationship between addition and subtraction
(B) how you can use a number line to help with the calculation
(C) how you can determine the sign of the result
Answers
- The number line allows us to interpret subtraction (or addition of a negative) geometrically; we can view it as a movement to the left on the number line with a distance equal to the number being subtracted.
- Lastly, the value of any expression a - b (where a and b are real numbers) is determined by the relative sizes of the numbers. If a > b, then a - b > 0 (a positive result). If b > a, then a - b < 0 (a negative result.

what is 7/12 plus 1/4
Answers
Find common denominators.
12x1=12
4x3=12
Multiple 4 by 3 in the second fraction to make a common denominator. What you do to the denominator you do to the numerator, so 1x3=3 and 4x3=12
7/12+3/12=10/12
To put into lowest terms divide the numerator and denominator by 2, since they share a factor.

Mary buys a dress and a pair of shoes. Before adding the tax she pays $ 48 for the dress which normally sells for $ 62, and she pays $ 34 for the shoes which normally sell for $46.
Answers
a. To find out how much Mary saved, we will have to subtract the sale price from the original price, and then add up the difference to find how much she saved. 62 - 48 is 14. 46 - 34 is 12. 14 + 12 = 26. Mary saved $26 by buying at the sale item price.
b. To find the amount of discount, we can write and solve a proportion, by setting it up like this: change/original = x/100. Change is the distance between two numbers and the original is the previous price. If you know about proportions, you cross multiply the values, and then divide each side by a number to isolate "x". If you solve each proportion correctly, here are your answers for each item:
Dress: ≈ 23% discount
Shoes: ≈ 26% discount
c. Okay. So when we add up the sales prices together, 48 + 34 is 82. In order to find the total amount with tax, we multiply the sale price, by (1 + r). In other words, add 1 to the rate in decimal form and multiply it by the total of the sales price. 82 * 106.5% (1.065) is 87.33. Mary paid a total of $87.33.
simplify.

If there are a number of different sounds being produced simultaneously, the resulting intensity is the sum of the individual intensities. How many decibels louder is the sound of quintuplets crying than the sound of one baby crying?
Answers
Δ L = level difference.
n = number of equal loud sound sources.
n = 5
10 × log10 5 = +6.9897 dB compared to the case that only one source is available.
The sound of quintuplets crying is 7 dB louder than the sound of one baby crying because a factor of five in intensity corresponds to a 7 dB increase in sound intensity level.
Explanation:The question asks how many decibels louder the sound of quintuplets crying would be compared to the sound of one baby crying. To calculate this, we need to understand that intercity levels in decibels (dB) are measured logarithmically. This means that for every ten-fold increase in intensity, the sound level goes up by 10 dB. We also know that a factor of five in intensity corresponds to an increase of 7 dB.
If one baby crying produces a certain sound intensity, then five babies (quintuplets) crying simultaneously would increase the intensity by a factor of five. Hence, the sound of quintuplets crying would be 7 dB louder than the sound of one baby crying, based on the given references.

2x^2+18 = 10
2x^2+18-18 = 10-18 <<--- step 1
2x^2 = -8
(2x^2)/2 = -8/2 <<--- step 2
x^2 = -4
At this point, it should be fairly clear there are no solutions. How can we tell? By remembering that x^2 is never negative as long as x is real.
Using the rule that negative times negative is a positive value, it is impossible to square a real numbered value and get a negative result.
For example
2^2 = 2*2 = 4
8^2 = 8*8 = 64
(-10)^2 = (-10)*(-10) = 100
(-14)^2 = (-14)*(-14) = 196
No matter what value we pick, the result is positive. The only exception is that 0^2 = 0 is neither positive nor negative.
So x^2 = -4 has no real solutions. Taking the square root of both sides leads to
x^2 = -4
sqrt(x^2) = sqrt(-4)
|x| = sqrt(4)*sqrt(-1)
|x| = 2*i
x = 2i or x = -2i
