en las matematicas para que concepto se usan las letras?
Answer:
En matemáticas, las letras son utilizadas en las ecuaciones, para representar a través de ellas valores no conocidos que deben ser dilucidados por quien realiza la ecuación. Las letras más utilizadas con este propósito son las letras X e Y.
Así, por ejemplo, se da una suma con un valor numérico y un valor faltante denominado X, con un resultado también numérico, con lo cual el valor de X surgirá del resultado de la ecuación planteada. Por ejemplo:
8 + X = 10
X = 10 - 8
X = 2
8 + 2 = 10

Ellen has 20 feet of ribbon. She uses 12 feet of ribbon to make pillows. She gives one-fourth of the remaining ribbon to her friend. How many inches of ribbon did Ellen give to her friend?
Answer: 2 ft
Step-by-step explanation:
Given
Ellen has 20 ft of ribbon
She uses 12 ft of ribbon to make pillow
The amount of remaining ribbon is [tex]20-12=8\ ft[/tex]
She gives one-fourth of the remaining to her friend i.e
[tex]\Rightarrow \dfrac{1}{4}\times 8=2\ ft[/tex]
So, she give 2 ft of ribbon to her friend.

Rotate an isosceles right triangle around a line that contains the triangle's hypotenuse
Answer:
See attachment 2 for the rotation
Step-by-step explanation:
The question has a missing figure
See attachment 1 for the missing figure of the isosceles right-triangle
Required
Rotate around the hypotenuse
From the attachment, the hypotenuse is along the blue vertical line along the y-axis.
So, when the isosceles triangle is rotated around the hypotenuse, the result of the rotation we get a composite figure that has two congruent solids.
Which is a cone of radius and height equal to half of the hypotenuse
See attachment 2 for the rotation

Jamie uses exactly 18 inches of dental floss every time she flosses her teeth. The package of dental floss she just bought contains 27 yards. How many times can Jamie floss her teeth with the amount of floss in this package?
Answer:
54 times
Step-by-step explanation:
36 inches = 1 yard
Since there are 27 yards, you multiply 36 by 27 = 972
If you use 18 inches each time, you would divide 972 by 18.
972/18= 54
So, Jamie could flow her teeth 54 times.

What is linear equation???
Answer:
an equation between two variables that gives a straight line when plotted on a graph. In mathematics, a linear equation is an equation that may be put in the form {\displaystyle a_{1}x_{1}+\cdots +a_{n}x_{n}+b=0, } where x_{1}, \ldots, x_{n} are the variables, and {\displaystyle b, a_{1}, \ldots, a_{n}} are the coefficients, which are often real numbers.

Step-by-step explanation:
Consider the provided information.
John made of a pound of fudge and Mary made of a pound of fudge.
Ricky takes the sum of the two amounts of fudge
The sum of the two amounts of fudge is 2 pound.
He divides it into three equal portions.

Hence Rickey keep 2/3 or 0.7 fudge.
The faces of a fair 6 - sided cube are numbered 1 through 6. What is the probability that a 2 will land face up on the next roll? Give your answer as a fraction in simplest form and the percent.
Answer:
You will have a 1/6 probability of getting a 2 that will land face up on the next roll.
Step-by-step explanation:
There is only one two on the cube, which means you will have 1 chance out of 6 of getting a 2.

Step-by-step explanation:
write the product in standard form: (x+4)(x-4)
Answer:
x² - 16
Step-by-step explanation:
Use the FOIL method here where
F = first
O = outer
I = inner
L = last
F = x * x = x²
O = -4 * x = -4x
I = 4 * x = 4x
L = -4 * 4 = -16
Combine the terms to get x² - 16.
Calinda is painting the design on her bedroom wall. The large circle has a diameter of 32 inches. To the nearest square inch, how much paint swill she need for the shared reign on
Answer:
804 inches
Step-by-step explanation:
Amount of paint she would need is equal to the area of the circle
Area of a circle = πr²
π = 3.14
r = 32/2 = 16
The diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
3.14 x 16² = 804 in

Alex receives 20 more sweets than Chris.
Work out the number of sweets Chris receives.
Answer:
Alex:Chris 35:15

7-3 (ratios)= 4
20 sweets= 4:1
20÷4= 5
5×7= 35 (how many sweets Alex got)
5×3= 15 (how many sweets Chris got)
Alex got 20 more sweets than Chris

THE CORRECT ANSWER IS 57 CM³
Explanation:
Let's consider the vertical block first, having height 9 cm, length 1 cm, width 5 cm.
Hence the volume of that block = l.w.h = 9×5×1 = 45 cm³
Coming to the horizontal block, having height 4 cm, width 3cm, & length 1 cm.
Hence the volume of that block will be = 4×3×1 = 12 cm²
The total volume of irregular figure = Volume of vertical block + horizontal block = 45+12 = 57 cm³
