Answer:
x = 5
Step-by-step explanation:
All the angles of a triangle add up to 180
83 + 61 + 4x + 16 = 180
160 + 4x = 180
180 - 160 = 4x
20 = 4x
20/4 = x
5 = x
Samra's guardians invested money for her into a 529 College Savings Plan, which compounds annually. The growth of the savings plan per year, x, can be represented by the exponential function f(x) = 500(1.03)x. What is the meaning of the y-intercept in the context of the problem?
The percent rate of change is 500%.
The initial value of the investment is $500.
The principal amount put into the savings plan is $1.03.
The average rate of change that is occurring is 1.03.
The y-intercept of the given exponential function would be represents the initial value of the investment is $500 which is the correct option (B).
What is an exponential function?An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.
It is a relation of the form y = aˣ in mathematics, where x is the independent variable
The given exponential function f(x) = 500(1.03)ˣ
Here x would be represented growth of the savings plan per year
To determine the y-intercept of the function
We have to substitute the value of x = 0 in the given function,
⇒ f(x) = 500(1.03)⁰
⇒ f(x) = 500(1)
⇒ f(x) = 500
Therefore, the y-intercept of the given exponential function would be represents the initial value of the investment is $500.

What multiplicity would you expect in a 1h nmr spectrum for the indicated proton(s)?
a. doublet
b. triplet
c. singlet
d. quintet
e. quartet
The multiplicity that would be in a 1H NMR spectrum for the indicated proton(s) is triplet.
The correct answer is an option (b)
NMR spectroscopy is used to examine the structure of molecules.
Another type of additional data available from 1H NMR spectroscopy is called multiplicity.
It is useful because it reveals how many hydrogens are on the next carbon in the structure.
1H NMR is a technique to confirm the structure of organic compounds or those that contain protons.
In 1H NMR technique, multiplicity provides information about the number of proton neighbors for a particular proton atom or group of atoms (neighboring typically refers to atoms within 3 bonds).
A solution-state proton spectrum is relatively fast to acquire, compared with other nuclei, and a lot of information about the structure of a compound can be deduced from it.
Therefore, the multiplicity that would be in a 1H NMR spectrum for the indicated proton(s) is triplet.
The correct answer is an option (b)

A bag contains 25 balls 20 of which are blue what percentage of balls are not blue
Answer:
20%
Step-by-step explanation:
20/25 = blue
This means 5/25 of the balls in the bag are NOT blue
(25-20 = 5)
We need to convert 5/25 to a percentage
[tex]\dfrac{5}{25} = \dfrac{5\times4}{25\times4}=\dfrac{20}{100}[/tex]
% = per cent
"per" means "out of"
"cent" means "one hundred"

Working together will take them 2 hours and 46 minutes which is 166 minutes.
What do we mean by equation?A mathematical statement made up of two phrases joined by an equal sign is known as an equation. 3x - 5 = 16 is an example of an equation. We get the value of the variable x as x = 7 after solving this equation.So,
Consider these work rates in terms of "greenhouses per hour," rather than "hours per greenhouse." Steve's work rate is one-fourth of a greenhouse per hour, while his son is one-ninth of a greenhouse per hour. Now, multiply each rate by the time t to obtain the percentage of the greenhouse that each paints, and add the products to obtain one greenhouse.The work equation is now:
[tex]\begin{aligned}&\frac{1}{4} t+\frac{1}{9} t=1 \\&\frac{9}{36} t+\frac{4}{36} t=1 \\&\frac{13}{36} t=1\end{aligned}\\\frac{36}{13} \cdot \frac{13}{36} t=\frac{36}{13} \cdot 1\\t=\frac{36}{13} \mathrm{hrs}\\\frac{36}{13} \cdot 60 \approx 166 \min[/tex]

The sum of Melanie's and her brother's ages is 35. Four years from now, Melanie will be 5 years older than her brother. How old is Melanie? How old is her brother?
Answer:
Sum of ages is 35
Since there are two persons and it says four years from now, each year 2 more years will be added on to the 35 so year 1: 2years Year 2:4years Year 3:6years Year 4 : 8years
35+8= 43
Remember that Melanie will be 5 years older ( which she should have already been)
so 43+5= 48 ( Melanie's age)

#14: m∠EFD = ____°
need answer
The value of ∠EFD is 107 ° as this angle is part of a linear pair .
When two lines cross at one point, a linear pair of angles is created. If the angles follow the intersection of the two lines in a straight line, they are said to be linear. A linear pair's total angles are always equal to 180°.
Given the two angles are ∠EFD and ∠DFG .
Now as they are on a straight line they form a linear pair .
As a part of a linear pair their sum add up to 180°.
Now substituting the given values :
11x - 3 + 6x + 13 = 180
or, 17 x + 10 =180
or, 17 x = 170
or, x = 10
Therefore the value of the ∠EFD is given as 11x - 3 = 110 - 3 = 107° .

A washer and a dryer cost $995 combined. The washer cost $45 more than the dryer. What is the cost of the dryer?
When a washer and a dryer cost $995 combined. If the washer cost $45 more than the dryer, then the cost of the dryer is $475
The combined cost of a washer and a dryer = $995
Consider the cost of a dryer as x
The washer cost $45 more than the dryer.
The cost of the washer = x+45
Then the equation will be
x+x+45 = 995

The probability of either A or B occurring will be 0.8.
What is probability?Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.
Being connected in a way that one excludes or prevents the other events from happening also: completely at odds despite the fact that their viewpoints did not conflict.
Suppose that A and B are mutually exclusive events for which P(A) = 0.3 and P(B) = 0.5.
Then the probability of either A or B occurring will be
P(AUB) = P(A) + P(B)
P(AUB) = 0.3 + 0.5
P(AUB) = 0.8
The probability of either A or B occurring will be 0.8.
