Answer:
El porcentaje de descuento fue del 10%.
Step-by-step explanation:
Para encontrar el porcentaje de descuento, puedes calcular la variación entre los dos precios ya que este será el porcentaje aplicado. Para hacerlo debes calcular la diferencia entre los dos precios restando el precio final menos el precio original y luego, debes dividir este resultado entre el precio original y multiplicar por 100:
Precio original=50
Precio final=45
((45-50)/50)*100
(-5/50)*100=-0.1*100=-10%
De acuerdo a esto, la respuesta es que el porcentaje de descuento fue del 10%.

V=s³
if s=1/3 of units
new volume will be
V new=(1/3)³=1/27 or 0.037unit³ is your answer
If the graph of a function increases as x increases and decreases
as x decreases, the degree must be _____
Answer:
Degree must be odd.
Step-by-step explanation:
In the end behavior of quadratic functions, the graph will either rise or fall as x increases infinitely. Likewise it will also rise or fall as x decreases infinitely.
Now, when x increases or decreases up to infinity(∞) and f(x) increases up to infinity (∞), it is said to be an even powered function and thus the degree is said to be even.
Similarly, when x increases up to infinity(∞) and f(x) increases up to infinity(∞), it is said to be an odd powered function and degree is odd.

h, where rr is the radius of the cone and hh is the height of the cone. Rewrite the formula to solve for hh in terms of rr and V.V.
Answer:
3V/ (pi r^2) = h
Step-by-step explanation:
V = 1/3 pi r^2 h
Solve for h
Multiply each side by 3
3V = 3 * 1/3 pi r^2 h
3V = pi r^2 h
Divide each side by pi r^2
3V/ (pi r^2) = pi r^2 h/ ( pi r^2)
3V/ (pi r^2) = h

Select the correct location on the table. Consider the following equation. Square root of 2x+3 = x/x+5 + 2 which row in the table is closest to the actual solution
Answer:
0.8 i guess
Step-by-step explanation:
The row including x=0.7 in the table is the closest to the actual solution for the expression [tex]\sqrt{(2x+3)}=\dfrac{x}{(x+5)}+2[/tex].
Solution of Algebraic EquationIn order to find the actual solution of any algebraic expression, we can graph it and the point at which the graph intersects the axis is its actual solution.
How to find the solution of the algebraic equation?First, we will find the actual solution of the expression [tex]\sqrt{(2x+3)}=\frac{x}{(x+5)}+2[/tex] by graphing it.
From the graph, we can see that the expression intersects when x=0.7 so, the actual solution is 0.7.
Thus, the 0.7 row in the table is the closest to the actual solution.

Rhona decided to buy a larger 1 1/4 pound package of baking flour rather than a 5/8 pound package. How much heavier is a larger package than a smaller one?
Answer:It is 5/8 of a pound heavier
Step-by-step explanation:
1 1/4 - 5/8=5/8
Answer:
The larger package is twice as heavy
Step-by-step explanation:
first make 1 1/4 into 5/4 and then multiply the top and the bottom by 2 to get a common denominator of 8. you will end up with 10/8. you can then subtract 5/8 from 10/8, leaving you with 5/8.

3. In a class of 50, the # of people with brown hair is 2 more than 5 times the number of people with red hair. How many
brown/red-haired people are there in the class? (Everyone in the class has either brown or red hair)
Answer:
8 red haired and 42 brown haired
Step-by-step explanation:
I chose a random number to start off with (which is 8) and I multiplied it by 5.
8•5=40 and then you have to add 2, so you get 42.
42+8 = 50
The equation would be (5x+2)+x where 'x' is the number of people with red hair.

I need help with 14 and 15!?
Answer:
15
Step-by-step explanation:
Pythagorean theorem states that the hypogenous of a right triangle is [tex]c=\sqrt{a^{2}+b^{2}}[/tex] . The hypogenous is the longest part of the triangle which is directly across from the 90 degree angle.
a = 9
b = 12
so,
[tex]c = \sqrt{9^{2}+12^{2} } = 15[/tex]
Kevin Hill deposited 15,483 pennies. He put 50 pennies in each penny roll. How many full rolls did he have?
Answer:
309 full rolls
Step-by-step explanation:
Find how many full rolls he had by dividing 15,483 by 50:
15,483/50
= 309.66
Since the question asks for full rolls, the answer has to be a full number.
So, the answer is 309 full rolls

Answer:
3. x = 11.6
4. f = 2 g = 2
Step-by-step explanation:
3) (3x - 7) + (4x + 6) = 90 --> x = 11.6
4) 3f + 1 = 5f - 15 ---> f = 2
6g - 5 = 3f + 1
6g = 3(2) + 6 ---> g = 2
The Diagram shows the net of a square pyramid and its dimensions
Answer:
SA = 84 ft²Explanation:
SA = the area of one side of the pyramid times 4 + the area of the base of the pyramid
Area of a triangle = (height × base)/2
Area of a sqaure = lenght²
given:
h = 4 ft | b = 6 ft | l = 6 ft
SA = 4(h×b×1/2) + l²
SA = 4(4×6×1/2) + 6²
SA = 4×12 + 36
SA = 48 + 36
SA = 84 ft²
