If Hermione paid 98 coins and Luna paid 28 coins, Hermione paid for 672 Chocolate Frogs.
We can start the problem by using algebra. Let x be the number of Chocolate Frogs that Hermione paid for. Then we know that:
x + (2016 - x) = 2016 (the total number of Chocolate Frogs)
Also, we know that the cost of the Chocolate Frogs Hermione paid is 98 coins, and the cost of the Chocolate Frogs Luna paid is 28 coins. Let's assume the cost of each Chocolate Frog is y. Then we can write:
x * y = 98 and (2016 - x) * y = 28
Now we have a system of two equations with two variables (x and y). To find the value of x, we can use any method to solve the system of equations, such as substitution or elimination.
Using substitution, we can solve for y in the second equation and substitute it into the first equation:
(2016 - x) * y = 28
y = 28 / (2016 - x)
x * (28 / (2016 - x)) = 98
x * (28 / (2016 - x)) = 98
x = 98 * (2016 - x) / 28
Solving for x, we get:
x = 2016/3
So Hermione paid for 2016/3 = 672 Chocolate Frogs.

Answer:
Hermione paid for 1,568 frogs.
Step-by-step explanation:
First, do 98 + 28. That will give you 126. Then do 2,016 / 126. That gives you 16. 16 x 98 = 1568 frogs.
Let's do Luna's to check our work.
28 x 16 = 448 frogs. 448 + 1568 = 2,016. So, Hermione paid for 1,568 frogs.

How many incas did the spanish kill on november 16 1532 o 100 o 600 o 1000 6000?
Spanish killed nearly 6000 Incas.
The Spanish conquistador and explorer Francisco Pizarro springs a trap on Atahualpa, the monarch of the Incas, in the year 1532. Atahualpa allowed roughly 6,000 unarmed men to attend the feast despite having almost 80,000 soldiers with him in the mountains. It took the Spanish a long time and much violence to conquer the Inca Empire. Pizarro's soldiers massacred the 6,000 Incans in approximately one hour.
The lone Spanish wounded were received by Pizarro himself, who injured his hand while saving Atahualpa's life. Pizarro retained Atahualpa in captivity while he prepared plans to conquer his empire because he understood that the emperor was worthy alive than dead. Atahualpa responded by appealing to his hostages' avarice and supplying them with money and silver in exchange for their release.

door wreaths. There are 20 meters of ribbon on a
spool. Write an equation that could be used to
determine the number of wreaths that Nicole
could decorate using one spool of ribbon. Solve.
Equation:
An equation that could be used to determine the number of wreaths that Nicole could decorate using one spool of ribbon is:
W = S / R
Define Equation.The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.
Define Algebraic expression.An algebraic expression in mathematics is an expression created using variables, constant algebraic numbers, and algebraic operations. A good example of an algebraic expression is 3x2 2xy + c.
An equation that could be used to determine the number of wreaths that Nicole could decorate using one spool of ribbon is:
W = S / R
where W is the number of wreaths, S is the total length of ribbon on the spool, and R is the length of ribbon used per wreath.
Plugging in the given values, we get:
W = 20 / 2.5
Solving for W, we get:
W = 8
So Nicole could decorate 8 wreaths using one spool of ribbon.

What are 4 ways to solve a problem?
The 4 ways to solve a problem are understanding the problem, devising a plan, carrying out the plan, look back.
A problem is any type of disruption from normality that is impeding progress. A problem can be time-consuming and requires too much energy to solve it.
Polya created his famous four-step process for problem-solving, which is used all over to aid people in problem-solving:
Step 1. Understand the problem.
x = a number
Step 2. Devise a plan (translate).
Twice the difference between a number and 1 is equal to 4 more than that number
Step 3. Carry out the plan (solve).
2(x - 1) = (x + 4)
2x - 2 = x + 4
2x - 2 - x = x + 4 - x
x - 2 + 2 = 4 + 2
x = 6
Step 4. Look back (check and interpret).
If we take twice the difference of 6 and 1, that is the same as 4 more than 6. Thus the final answer is 6.

d.

The amount he will have at the end of 3 years is $1596.55.
Option B is the correct answer.
What is compound interest?It is the interest we earned on the interest.
The formula for the amount earned with compound interest after n years is given as:
A = P [tex](1 + r/n)^{nt}[/tex]
P = principal
R = rate
t = time in years
n = number of times compounded in a year.
We have,
P = $1220
r = 9%
n = 12
t = 3 years
Amount = P [tex](1 + r/n)^{nt}[/tex]
A = 1220 [tex](1 + 9/12)^{36}[/tex]
A = 1220 [tex](1 + 0.75)^{36}[/tex]
A = 1220 x [tex]1.75^{36}[/tex]
A = $1,596.55
Thus,
The amount after 3 years is $1596.55.

Answer:
The surface area of this cuboid is 420 square inches.
Step-by-step explanation:
All we have to do is calculate each rectangle. For the width, we have 10 x 5 which is 50. Then we multiply it by 2 because we have two of those sides. Then we get 100. Then we have 11 x 5 which is 55. We multiply that by 2 and we get 110. Then we do that to the final two sides and we get 220. So the final answer if we add them all up is 420 square inches.
[tex]h + 54 = 4 {}^{2} - 16 \div 4[/tex]
Value of h = ???
Answer:
[tex]h = -42[/tex]
Step-by-step explanation:
First, subtract 54 from both sides.
[tex]h = 4^2 - 16 \div 4 - 54[/tex]
Then, evaluate the right-hand expression using the order of operations:
Parentheses
Exponents
Multiplication
Division
Addition
Subtraction
We'll first evaluate the exponent in 4²:
[tex]4^2 = 4 \times 4 = 16[/tex]
[tex]h = 16 - 16 \div 4 - 54[/tex]
Next, we can evaluate the division:
[tex]16 \div 4 = 4[/tex]
[tex]h = 16 - 4 - 54[/tex]
Finally, perform the subtraction.
[tex]16 - 4 - 54 = -42[/tex]
[tex]h = -42[/tex]
Answer:
[tex] \sf \: h = - 42[/tex]
Step-by-step explanation:
Given equation,
→ h + 54 = 4² - 16 ÷ 4
Now the value of h will be,
→ h + 54 = 4² - 16 ÷ 4
→ h + 54 = 16 - 4
→ h + 54 = 12
→ h = 12 - 54
→ [ h = -42 ]
Hence, value of h is -42.

What are the domain and range of the function?
f(x) = ³√x + 2
The domain of the function f(x) = ∛x + 2 is all real numbers such that x ≥ 0. This is because the cube root function is defined only for non-negative numbers.
What do a function example's range and domain mean?
A straightforward function, such as f(x) = x2, can have a domain (what goes in) of just the counting numbers 1, 2, 3, etc., and a range (what comes out) of the set 1, 4, 9, etc. Another function, g(x) = x2, may have an integer domain of..., -3, -2, -1, 0... 1, 2, 3, and its range is..., 1, 4, 9,...
For the range, the function f(x) = ∛x + 2 is a monotonically increasing function over the domain, which means that it increases as the input x increases. Therefore the range of f(x) = ∛x + 2 is all real numbers greater than or equal to 2
So the domain is x>=0 and the range is y>=2

Suppose you invest $2000 at an annual interest rate of 8.2% compounded continuously. How much will you have in the account after 10 years
Answer:
$3,640
Step-by-step explanation:
8.2% as a decimal is 0.082. multiply 2000 by 0.082, and you get your interest rate/the interest you pay each year, which would be 162. multiply 162 by ten to get your interest for all ten years, since 162 was simply the rate, and you get 1,640. add the original 2000 onto that, and you get 3,640.

What is quadrilateral?There are four sides, four vertices, and four angles in a closed quadrilateral. It has a polygonal shape. It is produced by joining four non-collinear points. The total internal angle of a quadrilateral is always 360 degrees.
The English word quadrilateral is derived from the Latin words quadra, which means four, and latus, which means sides. Each of a quadrilateral's four sides does not always have to be the same length.
Given a quadrilateral,
in which opposite sides are parallel,
so, When a transversal cuts between two parallel lines, the interior angles on the same side of the transversal are additional to 180°.
36° + a° = 180°
and 113° + b° = 180°
a° = 180° - 36° = 144°
and b° = 180° - 113°
b° = 67°
Hence the values of a° is 144° and b° is 67°.
