What is congruence in Triangle?Congruent triangles are triangles that have the same size and shape. This means that the corresponding sides are equal and the corresponding angles are equal.
Given that:
∠P ≅ ∠Q and Line Segment RS bisects ∠PQR.
In ΔPRS≅QRS ,
∠P≅∠Q (Given)
∠PRS≅∠QRS (Definition of angle bisector)
RS≅RS (reflexive property of congruence)
so,ΔPRS≅QRS (By AAS congruence)
Therefore, by the property of (Angle-Angle-Side)AAS postulates ΔPRS≅QRS

A circle with the center C (4, -2) contains the point D (8,1). What is the equation of the line perpendicular to the radius of the circle passing through point C?
Answer:
y = -4x/3 + 10/3
Step-by-step explanation:
We find the slope of CD and get (-2 - 1)/(4 - 8) = -3/-4 = 3/4
The slope of a perpendicular line is the opposite reciprocal of the slope of the line it's perpendicular to, so we get a slope of -4/3.
We can use point-slope form and get (using point C):
y - (-2) = (-4/3)(x - 4) -->
y + 2 = -4x/3 + 16/3 -->
y = -4x/3 + 10/3

They need to park the Mystery Machine. They could
either park in the lot that charges $5 and then $2 an
hour, or they could park using the meter on the street
that charges $3.75 per hour.
Write an equation that describes when the cost is the
same at both locations (the parking lot and on the
street).
Answer:
12 hours in the street=20 hours in the lot
Step-by-step explanation:
Well basically if you're at the street for 12 hours it will add up to 45 dollars. subtract the 5 starting dollars and you get 40. Divide 40 by 2 and you get 20. What does this mean? This means that in 12 hours on the street you can match the same amount of money if you were in the lot for 20 hours.
The temperature of a cup of coffee varies according to Newton's Law of Cooling: dT dt equals negative k times the quantity T minus A, where T is the temperature of the coffee, A is the room temperature, and k is a positive constant. If the coffee cools from 100°C to 90°C in 1 minute at a room temperature of 25°C, find the temperature, to the nearest degree Celsius of the coffee after 4 minutes.
74
67
60
42
Answer:
(b) 67
Step-by-step explanation:
A solution to the differential equation describing the temperature according to Newton's Law of Cooling could be written as ...
T = (final temp) + (initial difference)×(decay factor)^t
where the decay factor is the fraction of change during 1 unit of time period t.
__
Here, the initial difference of 100-25 = 75 degrees decays to 90-25 = 65 degrees in 1 minute. So, the units of t are minutes, the decay factor is 65/75, the initial difference is 75 degrees, and the final temperature is 25 degrees. That lets us write the equation as ...
T = 25 +75(65/75)^t
Then for t=4, the temperature is ...
T = 25 +75(13/15)^4 ≈ 67.3 . . . . degrees
After 4 minutes the temperature of the coffee is about 67 degrees.
Your teacher asks the class to evaluate the expression (3³)¹. Your classmate gives an incorrect answer of 81. Evaluate the expression. Then find the likely error. **PLEASE FIND THE ERROR I DON'T NEED THE ANSWER I KNOW ITS 27**
Answer:
see explanation
Step-by-step explanation:
The most likely error is adding the exponents instead of multiplying them, that is
[tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex] , then [tex](3^{3}) ^{1}[/tex] = [tex]3^{3(1)}[/tex] = 3³ = 27
However
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] ← the student may have used this definition to obtain 81

The mass of the apples harvested from a particular orchard follows a nearly normal distribution with a mean of 94 grams and a standard deviation of 27 grams. What size sample is needed to get a standard error of 3
The sample size needed to get a standard error of 3 is 81
How to determine the sample size?The given parameters are:
Mean = 94Standard deviation = 27Standard error = 3The standard error is calculated using:
[tex]SE = \frac{\sigma}{\sqrt n}[/tex]
So, we have:
[tex]3= \frac{27}{\sqrt n}[/tex]
Divide both sides by 3
[tex]1= \frac{9}{\sqrt n}[/tex]
Square both sides
1 = 81/n
Multiply both sides by n
n = 81
Hence, the sample size needed to get a standard error of 3 is 81

Solve. Use the discount equation
S = R − rR, where S is the sale price, R is the regular price, and r is the discount rate.
An exercise bike is on sale for $320, having been marked down 20% off the regular price. Find the regular price.
Answer:
[tex]\$ 400[/tex].
Step-by-step explanation:
In this question, [tex]S[/tex] (sales price) and [tex]r[/tex] (discount rate) are both given. The unknown is the regular price, [tex]R[/tex].
Rearrange the discount equation to solve for [tex]R[/tex] in terms of [tex]S[/tex] and [tex]r[/tex].
[tex]S = R - r\, R[/tex].
[tex]S = (1 - r)\, R[/tex].
Divide both sides by [tex](1 - r)[/tex]:
[tex]\displaystyle \frac{S}{1 - r} = \frac{(1 - r)\, R}{1 - r}[/tex].
[tex]\begin{aligned}R &= \frac{S}{1 - r}\end{aligned}[/tex].
It is given that [tex]S = 320[/tex]. A mark-down of [tex]20\%[/tex] is equivalent to a discount rate of [tex]r = 20 / 100 = 0.20[/tex]. Substitute in [tex]S[/tex] and [tex]r[/tex] to find the value of [tex]R[/tex]:
[tex]\begin{aligned}R &= \frac{S}{1 - r} \\ &= \frac{320}{1 - 0.2} \\ &= \frac{320}{0.8} \\ &= 400\end{aligned}[/tex].
Thus, the regular price would be [tex]\$ 400[/tex].

During a clothing store's Bargain Days, the regular price for T-shirts is discounted by $6. There is a state sales tax of 5%, and the $6 discount is applied before the
sales tax is calculated. A). Write an expression that shows the regular price r of a T-shirt minus the $6 discount. B). Write a rule for the function p(r) that expresses the
final price p of a T-shirt with the discount applied and sales tax added. C). How much would you pay during Bargain Days for a shirt regularly priced at $20.00?
Answer:
A) The expression that shows the regular price minus the discount is r - 6
B) The function is p(r) = 1.05r - 6.3
C) You would pay $14.7 during Bargain Days
Step-by-step explanation:
∵ The regular price is r
∵ The discount on it is 6%
∴ The price after the discount = r - 6
A) The expression that shows the regular price minus the discount is
r - 6
∵ The state sales tax is 5% applied after the discount
∴ The sales tax = 5%(r - 6)
→ Change 5% to decimal y dividing it by 100
∵ 5% = [tex]\frac{5}{100}[/tex] = 0.05
∴ The sales tax = 0.05(r - 6) = 0.05(r) - 0.05(6)
∴ The sales tax = 0.05r - 0.3
∵ p is the price of the T-shirt with discount and sales tax
→ Add the sales tax to the regular price minus the discount
∴ p(r) = r - 6 + 0.05r - 0.3
→ Add the like terms
∴ p(r) = (r + 0.05r) + (-6 - 0.3)
∴ p(r) = 1.05r + (-6.3)
∴ p(r) = 1.05r - 6.3
B) The function is p(r) = 1.05r - 6.3
∵ The regular price of a shirt is $20
→ Substitute r by 20 in the function above to find how much you would
pay during the Bargain Days
∴ p(20) = 1.05(20) - 6.3
∴ p(20) = 21 - 6.3
∴ p(20) = $14.7
C) You would pay $14.7 during Bargain Days

Thickness of a 500 sheet stack of notebook paper is 5 cm.
What is Measurement units?
A measurement unit is a standard quality used to express a physical quantity.
Given that;
Thickness of a sheet of notebook paper = 0.004 inch
Now,
1 inch = 2.54 cm
Hence, Thickness of a sheet of notebook paper = 0.004 inch
= 0.004 × 2.54 cm
= 0.01016 cm
= 0.01 cm
So, Thickness of a 500 sheet stack of notebook paper = 500 × 0.01
= 5 cm
Thus, Thickness of a 500-sheet stack of notebook paper is 5 cm.
