The diagram shows two proportional right triangles.
What is the perimeter of the larger triangle?
Answers
Answer:
48 units.
Step-by-step explanation:
Since the triangles are similar (proportional), their dimensions are increased at the same ratio at any point, which means their perimeter too. So the base of the larger triangle is twice as long as the base of the smaller triangle.
The perimeter of the smaller triangle is 10 + 6 + 8 = 24 units.
24 * 2 = 48. Because the ratio of increase is 2:1 from the bigger triangle to the smaller triangle.

We spent a total of 40.2 + 24.5+ 37.8 = $102.50
Explain about the fractions?A fraction is a metric unit for describing a piece or component of a whole. It represents the appropriate parts of the totality. A fraction is made up of two parts: the numerator and the denominator. The number at the top is the numerator, and the number at the bottom is the denominator.
Fractions are used to represent the parts of an entity or collection of entities. The components of a fraction are two. The figure at the top of the line is the numerator. It provides information on how many equal sections from the total or collection were taken. The number that appears below the line is the denominator.
We multiply the initial price by the fractions' decimal conversions to determine how much we spent. The quantities are then combined.
You purchased sneakers for $60 and paid 2/3 of that amount, or $0.6666, for a total of $40.20, saving $19.80.
Sweater costs $35 and you paid $7.50 for it, saving you $10.50. 35(0.7)=$24.50.
You paid $45 for a jacket, and since 5/6=0.8333, 45(0.84)=$37.80, you made a $7.20 profit.

How to do 5 choose 3 on calculator?
Answers
To do 5 choose 3 on calculator, there are many methods including typing the input the mathematical expansion or in scientific calculators according to the model, there is way to represent 5C3.
The notation 5 choose 3 (also known as "5C3" or "5 comb 3") represents the number of ways to choose 3 items from a set of 5 items, also known as the binomial coefficient. It is equivalent to the formula:
5C3 = (5!) / (3! × (5-3)!)
Where "!" denotes factorial, which is the product of all positive integers up to that number.
To calculate 5C3 on a calculator, you can use the above formula and input it as follows:
5!/(3!×(5-3)!)
Most calculators have a button for factorial (symbolized by "!" or "n!"), so you can use that to calculate the factorials in the formula.
For example, on a basic calculator, you can input the following:
5!/(3!×2!)
and then press enter or the "=" button to get the result which is 10.
On some scientific or graphing calculators the notation is different, it could be represented as "comb(5,3)" or "5C3" and you just need to enter it as such.

the number of shirts has to be an integer (you can not sell "part" of a shirt) n >= 65
They need at least $1,150
They have already saved $700
They are selling shirts with a profit of $7.00 per shirt
If they sell n number of shirts, they will earn n times $7.00
Since they have already 700, they will earn a total of 700 + 7n
If this quantity has to be equal or greater to 1,150, we can write:

Using Pythagoras theorem to solve the right angle triangle, the height of the building is 14.87 feet
What is Pythagoras TheoremPythagoras Theorem states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. This can be expressed as an equation:
x² = y² + z²
where x is the hypothenuse and y, z are the legs of the right angle triangle.
To determine the height of the building in which the ladder will reach, we have to use Pythagoras theorem for that.
x² = y² + z²
15² = 2² + z²
z² = 15² - 2²
z² = 221
z = √221
z = 14.87 feet
The height is 14.87 feet

x
. For convenience, order your terms so that the biggest powers of x
x
come first, and they get smaller as you go, so that the last term is one without an x
x
, if you have one. If this isn’t a polynomial, then this equations isn’t algebraic, so stop following this guide.
Possible mid-step, if you don’t have a term without an x
x
, then x=0
x
=
0
is a solution, and you can divide by the smallest power of x
x
so that now you should have a term without an x
x
. If there’s no smallest power of x
x
, you started with 0=0

=
0
which is always true. If the term without an x
x
is the only one, your equation looks like a=0
a
=
0
for some nonzero a
a
, so you’re out of solutions and can stop here.
Next, figure out the degree of P

Another possible mid-step, if your degree is more than 4

. If you don’t have a degree 4
4
equation, then you might be out of luck. At this point, I think we can no longer call the equation “basic”, as it might not even have a closed-form solution.
Lastly, at this step you should have a polynomial of degree between 1

and 4

, in which case you will use the corresponding formula: linear, quadratic, cubic, or quartic. The term “linear formula” isn’t really in wide use, but it simply states that the equation

So there you go, a more or less complete tutorial on how to solve any “basic” “algebraic” equation (for the definitions given above). There are a couple of heuristic techniques you can also try before giving up, such as factoring by grouping, the rational root theorem, and Descartes rule of signs, but none of these techniques are guaranteed to be of any help. Most polynomials of degree 5 or greater don’t have closed-form solutions, so don’t be discouraged if you can’t find them. At that point, if you really need those solutions, you can try numerical methods, but I’ll leave that out of this answer.

What is circumference of a circle?
The measurement of the circle's perimeter, also known as the circle's boundary, is called its circumference . The radius of the circle is considered when applying the formula to determine the circumference of the circle.
Circumference of circle(C) = 2πR
where,
R represents the radius of the circle
π is a constant with an approximate value of 3.14
Now, it is given that the tip of a minute-hand travels 103. 62mm in one hour which means that the minute hand moves 360 degrees.
This means that C= 103.62
So, using the concept of circumference of a circle,
C= 2πR
103.62= 2*3.14*R
So, R= 103.62/6.28
R=16.5mm

Aisha has 50 chocolates she fills 3 boxes and has 2 left over How many chocolates does she have left? Write it as an equation
Answers
Aisha has 2 chocolates left. You can represent the problem as an equation as follows:
x = 3b + 2Where x is the total number of chocolates, b is the number of boxes filled and 2 is the remaining chocolates left.
Since we know that Aisha has 50 chocolates, we can substitute this value for x in the equation:
50 = 3b + 2
Solving for b, we find that b = 16. So, Aisha filled 16 boxes and had 2 chocolates left over. The equation is true, and Aisha has 2 chocolates left.
It's worth noting that this is a simple algebraic equation, we can use the same equation to find the number of chocolates given the number of boxes and remaining chocolates, or to find the number of boxes given the number of chocolates and remaining chocolates or to find the remaining chocolates given the number of boxes and the number of chocolates.

(f(3) - f(-4)) / (3 - (-4)) = (sqrt(25 - 9) - sqrt(25 - 16)) / (3 - (-4)) = (-2sqrt(7) + 4sqrt(3)) / 7
b) To find the derivative of f(x), we need to use the power rule and the chain rule. The power rule states that the derivative of x^n is nx^(n-1), and the chain rule states that the derivative of f(g(x)) is f'(g(x)) * g'(x).
So, the derivative of f(x) = sqrt 25 - x^2 is:
-2x
c) To find the equation of the line tangent to the graph of f at x = -3, we need to use the point-slope form of a line, which is:
y - y1 = m(x - x1)
where m is the slope of the line (which is f'(-3) = -6), (x1, y1) is the point on the graph where the line touches (which is (-3, f(-3)) = (-3, sqrt(25 - 9) = 2sqrt(7))
so we have: y - 2sqrt(7) = -6(x + 3)
d) To check if g(x) is continuous at x = -3, we need to check if the limit of g(x) as x approaches -3 exists and is equal to g(-3).
Since g(x) = f(x) for -5 <= x <= -3 and g(x) = x + 7 for -3 <= x <= 5, we have:
g(-3) = f(-3) = sqrt(25 - 9) = 2sqrt(7)
and the limit of g(x) as x approaches -3 is:
lim x->-3 g(x) = lim x->-3 (x + 7) = -3 + 7 = 4
Since g(-3) = 2sqrt(7) and lim x->-3 g(x) = 4, g(x) is not continuous at x = -3.
