Answer:a + b + c = 180 ( sum of angles in a triangle )
c + d = 180 ( adjacent angles are supplementary ), thus
a + b + c = c + d ( subtract c from both sides )
a + b = d

how do you find the percentage of exponential decay?
Answer:
When an original amount is reduced by a consistent rate over a period of time, exponential decay is occurring. This example shows how to work a consistent rate problem or calculate the decay factor. The key to understanding the decay factor is learning about percent change.

Similar or not similar?
Answer:
They are similar.
Step-by-step explanation:
All of the sides are of equivalent length (technically), the bigger triangle is just the smaller triangle doubled in size.
Plz answer asap!!!!!
Answer:
Let ΔABC and ΔDEF be two triangles such that ∠A = ∠D and ∠B = ∠E.
∠A + ∠B + ∠C = 180 0 (Sum of all angles in a Δ is 180)
∠D + ∠E + ∠F = 180 0 (Sum of all angles in a Δ is 180)
⇒ ∠A + ∠B + ∠C = ∠D + ∠E + ∠F
⇒ ∠D + ∠E + ∠C = ∠D + ∠E + ∠F (since ∠A = ∠D and ∠B = ∠E)
⇒ ∠C = ∠F
Thus the two triangles are equiangular and hence they are similar by AA.

Mr. Bon Jovi ordered some pizzas to be delivered. The bill for the pizza was m dollars. Mr. Bon Jovi tipped the pizza delivery driver 15% of the bill.
a. Write an expression for the total amount of money Mr. Bon Jovi paid.
Answer:
t=m(1.15)
Step-by-step explanation:
lets say t=total payment after tip.
m=order price
we know that 15%- .15 so add .15 to 1 to get 1.15 which is what you multiple by m to get the total price, or t

Which expression shows the perimeter of the triangle in simplest form?
A. 6x + 7
B. 7x + 5
C. 5x + 3
D. 6x + 3
Answer:
D. 6x + 3
Step-by-step explanation:
A perimeter is just the sum of all sides of a shape.
First, write an equation to add all sides of the triangle:
(x + 4) + (3x - 2) + (2x + 1)
What is inside the parentheses is all already simplified. Also, it is addition, so the order in which we add does not matter. So, we can now get rid of the parentheses and combine like terms:
x + 3x + 2x + 4 -2 + 1
6x + 3
And that's our final answer: 6x + 3

A. They should have canceled our factors to simplify at the end
B. They shouldn’t have combined like terms
C. They didn’t get common denominators
D. They needed to cancel out X’s
Answer:
The correct answer would be C they did not get common denominators
Step-by-step explanation:
You can only add fractions with common denominators for example you can not add 1/7 and 1/8 because the denominators are not equivalent.
I hope this helps you!!
Which of the following statements are true for this function? Select all that apply.
A. The function is discontinuous at x=-1
B.The function is discontinuous at x=1
C. The value of the function is never negative
D. x=1 is not the domain of the function
E. The value of the function at x=-1 is 0
F. The value of the function at x=1 is 0
Answer:
A, C, and E
Step-by-step explanation:
Given is a graph of a function first a straight line, followed by a semi circle centred at the origin and another piece of straight line not connected to the other graph.
We can see that the funciton is discontinuous at x=1 since
right limit = 1 and left limit =0
x=1 is in the domain .
f(-1) =0 is right
But f(1) =0 is incorrect
Thus correct options are
The function is discontinuous at x = 1.
The value of the function is never negative.
The value of the function at x = -1 is 0

Drag the correct description to tell whether the graph represents a function.
Answer:
1) Not a function 2) function 3) function
Step-by-step explanation:
Use the vertical line test. If you draw a line on every vertical line on the graph and you see two points, it is not a function.
The graph is shown in options B) and C) represents a function and this can be determined by carefully observing the given graph.
Check all the options in order to determine whether the graph represents a function or not.
A) The graph shows in this option that the two lines are intersecting at (x = 2). Therefore, this graph does not represent a function.
B) The graph shows in this option is in the shape of a parabola whose vertex is at (-2,0). Therefore, this graph does represent a function.
C) The graph shows in this option is in the shape of a wave. This graph may represent a trigonometric function. Therefore, this graph does represent a function.

Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree? Use an example to explain
Answer:
I do not agree because Mario's claim is not general.
Step-by-step explanation:
Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.
And a denominator is the divisor in a given fraction.
Considering the following fractions whose denominators are prime numbers:
[tex]\frac{2}{3}[/tex] = 0.66666666...
[tex]\frac{1}{7}[/tex] = 0.142857142
[tex]\frac{5}{11}[/tex] = 0.45454545...
[tex]\frac{3}{13}[/tex] = 0.23076923
[tex]\frac{1}{7}[/tex] = 0.142857142
It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.

Abby can buy a 7lb. bag of dry cat food for $7.49, or she can purchase a 3lb. bag for $5.40. Which size is the best buy?
Answer:
The 7 pound bag.
Step-by-step explanation:
7.49 divided by 7 is 1.07
5.40 divided by 3 is 1.80
So, the 7 pound bag would be a better deal because 1.07 is less than 1.80.
