In the diagram, triangle QRS is congruent to triangle XYZ. Find the measure of angle R.
Answers
Answer:
the correct answer is C. 75°
The value of ∠R = 75⁰
What are congruent triangles?The measurements of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of their corresponding sides and angles are equal, two triangles are said to be congruent.
Given ΔQRS ≅ ΔXYZ
for congruency the sides and angle of both the triangles should be equal so for ΔQRS and ΔXYZ ; QR = XY, QS = XZ, and RS = YZ and
∠Q = ∠X, ∠S = ∠Z and ∠R = ∠Y
from figure ∠Q = ∠X = 55⁰, ∠S = ∠Z = 50⁰
sum of angle of triangle is 180⁰,
∠Q + ∠S + ∠R = 180⁰
∠R = 180 - 55 - 50
∠R = 75⁰
Hence ∠R = 75⁰

A customer opens a savings account
that applies 4% compound interest
annually. If the initial investment is
$200.00, how much money will be in
the account at the end of two years?
Please explain
Answers
Answer:
$216.32
Step-by-step explanation:
The formula for compound interest is given as:
A = P(1 + r/n)^nt
Where:
A = Amount after t years= ??
P = Principal = Initial amount invested $200
r = Interest rate = 4%
t = time in years = 2
n = Compounding frequency = Annually = 1
First, convert R percent to r a decimal
r = R/100
r = 4%/100
r = 0.04 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 200.00(1 + 0.04/1)^(1 × 2)
A = $ 216.32
The amount of money that will be in the account at the end of two years is $216.32

Answers

Answer:
(-18, 14), (-9, 9), (9, -1), (18, -6)
Step-by-step explanation:
Since there is a 9 in the denominator of the coefficient of x, we will get integer solutions only if x is a multiple of 9. Suitable values meeting the problem requirements are x ∈ {-18, -9, 9, 18}. Then the corresponding values of y are ...
y = -5/9(-18) +4 = 10 +4 = 14
y = -5/9(-9) +4 = 5 +4 = 9
y = -5/9(9) +4 = -5 +4 = -1
y = -5/9(18) +4 = -10 +4 = -6
The four solutions we have found are ...
(-18, 14), (-9, 9), (9, -1), (18, -6)

Sonia decides to leave a 14% tip after eating dinner at Fresh Catchery. If the bill is $27.78, how much should she pay?
Answers
Answer:
$31.67
Step-by-step explanation:
14/100x27.78= about 3.89
3.89+27.78=31.67
$31.67
The amount that Sonia will pay is $31.67.
Amount of bill = $27.78
Percentage of tip = 14%
Amount of tip = 14% × $27.78
= 0.14 × $27.78
= $3.89
Total amount to be paid will then be;
= $27.78 + $3.89
= $31.67
In conclusion, Sonia will pay $31.67.

Solve the differential equation: y"-5y'+6y=0
Answers
The solution to the differential equation in this problem is given as follows:
y(t) = Ae^(3t) + Be^(2t).
How to solve the differential equation?The differential equation for this problem is given as follows:
y'' - 5y' + 6 = 0.
It is a simple linear and homogeneous second order differential equation, hence it can be solved with the characteristic equation method.
The characteristic equation for the differential equation is given as follows:
r² - 5r + 6 = 0.
The roots for the characteristic equation are obtained by finding the linear factors and using the factor theorem as follows:
(r - 3)(r - 2) = 0.
Hence:
r - 3 = 0 -> r = 3.r - 2 = 0 -> r = 2.These are real and non-repeated roots, hence the solution is given as follows:
y(t) = Ae^(3t) + Be^(2t).
In which A and B are constants depending on the initial conditions for the differential equation.

What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The measure of the exterior angle is given as,
Exterior angle = 180° - Interior angle
Exterior angle = 180° - 156°
Exterior angle = 24°
The total number of sides of the polygon will be given as,
Exterior angle = 360° / (Number of sides)
24° = 360° / n
n = 360° / 24°
n = 15
The number of sides that the original building has will be 15 sides.
