The sum in scientific notation will give:
7.76*10⁶
How to find the sum in scientific notation?
Here we want to find the sum between the numbers (7.3*10⁶) and (4.6*10⁵).
To sum these numbers, we need to have the same exponent in the "10", then we can rewrite:
7.3*10⁶ = 73*10⁵
Now the sum will be:
73*10⁵ + 4.6*10⁵
Taking a common factor we get:
73*10⁵ + 4.6*10⁵ = (73 + 4.6)*10⁵ = 77.6*10⁵
Now we want to go back to scientific notation, so we need to move the decimal point one time to the left, we will get:
77.6*10⁵ = 7.76*10⁶
That is the outcome of the sum.

Step-by-step explanation:
Write a function for each situation. Then find the value of each function after five years. Round to the nearest dollar. A $ 12,500 car depreciates 9 % each year.
7800 is the value of each function after five years.
With an example, what is compound interest?
When you add the interest you have already earned back into your principal balance, you are earning compound interest, which increases your profits. Consider that you have $1,000 in a savings account earning 5% interest annually. If you made $50 in the first year, your new balance would be $1,050.The formula is: A = P( 1 + r )ⁿ
r = 0.09
As here the value of the car depreciates every year, so we need to plug the value of as negative. So, - 0.09
Now plugging the above values into the formula, we will get
A = 12500 ( 1 - 0.09)⁵
A = 12500 * ( 0.91)⁵
A = 12500 * 0.6240321451
A = 7800.40181375 ≈ 7800

Alma is choosing a new smartphone and cellular service plan. let p be the phones price in dollars, m be the cost of the selected plan in dollar per month, and c be alma's total cost in dollars after time t, measured in months of service. write an equation that expresses c in terms of p, m, and t. then solve your equation for t.
The equation which expresses c in terms of p, m and t as in the task content is; c = mt + p and the solution of the equation for t is; t = (c -p)/m.
What is the equation of the situation such that c is expresses in terms of p, m and t?It follows from the fact that the rate of change, m is constant in the situation described. Hence, the equation is a linear equation.
On this note, the required equation which represents total cost, c in terms of p, m and t can be written as;
C = mt + p.
Hence, to solve the equation above for t;
Subtract p from both sides so that;
c - p = mt
Divide both sides by m;
(c - p)/m = t.
Ultimately, The equation which expresses c in terms of p, m and t as in the task content is;
c = mt + p
and the solution of the equation for t is;
t = (c -p)/m.

In 2010, the population of a city was 228,000. From 2010 to 2015, the population grew by 7.7%. From 2015 to 2020, it fell by 4.2%. To the nearest 100 people, what was the population in 2020?
The population in the city in 2020 to the nearest 100 is 235242.65.
The population of the city was 228,000 in the year 2010.
From 2010 to 2015, the population grew by 7.7%.
The population decreases by 4.2 % from 2015 o 2020.
Initially, the population of the city is 228,000.
From 2010 to 2015,
The city's population increased by 7.7%.
7.7% of 228,000 = ( 7.7 / 100) × 228,000 = 17556
The population of the city from 2010 to 2015 = 228,000 + 17556 = 245556
From 2015 to 2020,
Now, the city's population decreases by 4.2%.
4.2% of 245556 = ( 4.2 /100) × 245556 = 10313.352.
Therefore,
The population of the city in the year 2020 = 245556 - 10313.352 = 235242.648
Therefore, the population in the year 2020 to the nearest 100 is 235242.65.

A kitten has 5 claws on its paw, a chicken has 4. there are 57 kittens and chickens in the yard and they all have 768 claws. how many kittens and chickens are in the yard?
Using algebraic expressions and equation, there are 26 kittens and 31 chickens in the yard.
An algebraic expression is a number, variable, or the combination of both and operational symbols. On the other hand, an equation is the equality of two expressions separated by "=".
Given that there are 57 kittens and chickens in the yard, we can express this as:
x + y = 57 ⇒ x = 57 - y (equation 1)
where x = number of kittens
y = number of chickens
If a kitten has 5 claws on each of its 4 paws, and a chicken has 4 claws in each of its 2 feet, and they all have 768 claws, then
5(4)x + 4(2)y = 768 ⇒ 20x + 8y = 768 (equation 2)
Substitute equation 1 to equation 2 and solve for y.
20(57 - y) + 8y = 768
1140 - 20y + 8y = 768
-12y = -372
y = 31
number of chickens = 31
Substitute the value of y in either of the two equations and solve for x.
x = 57 - y
x = 57 - 31
x = 26
number of kittens = 26

What is the value is 1/a+1/b+1/c
When a, b and c are the polynomials roots
Answer:
2/3.
Step-by-step explanation:
α + β + γ = -b/a
αβ + βγ + γ α = c/a
αβγ = -d/a
These are the relation between the roots α, β and γ and the coefficients of the cubic equation:
P(x) = ax^3 + bx^2 + cx + d
Our equation is:
P(x) = 4x³ – x² − 6x + 9
So, for the above equation:
a + b + c = -(-1)/4 = 1/4
ab + ac + bc = -6/4 = -3/2
abc = -9/4.
1/a + 1/b + 1/c
= (bc + ac + ab) / abc
So, plugging in the above values:
this = (-3/2) / (-9/4)

**USE LET STATEMENTS, AND THEREFORE STATEMENTS**
The number of hours the polls open on the election day was 9 hours
From the question, we are to determine how long the polls opened on the election day
From the given information,
6,504 people vote in the advance polls for a riding prior to the election
and
A total of 10,167 people voted in that riding
Thus,
The number of people that voted on the election day = 10167 - 6504
Number of people that voted on the election day = 3663
Also, from the given information
The polling stations for the riding record an average of 407 voters per hour
Then,
Number of hours the polls open on election day = Number of people that voted on the election day ÷ Average number of voters per hour
Number of hours the polls open on election day = 3663 ÷ 407
Number of hours the polls open on election day = 9 hours
