Answer:
33
Step-by-step explanation:
f(4) = 4(4) - 3 = 16 - 3 = 13
g(-5) = -2(-5) + 10 = 10 + 10 = 20
13 + 20 = 33
find the size of x and y
this is a figure of parallelogram
Answer:
x = 75° , y = 105°
Step-by-step explanation:
Opposite angles in a parallelogram are equal , then
x = 75°
Consecutive angles in a parallelogram are supplementary, sum to 180° , so
x + y = 180° , that is
75° + y = 180° ( subtract 75° from both sides )
y = 105°
Enrique says that when you know the diameter of a circle you can find the radius. how can find the radius. How can he find the length of radius if he knows the length of the diameter?
and no there's no example
Answer:
The radius is always half of the diameter.
Step-by-step explanation:
Well, the radius is always half of the diameter. For example, if the diameter is 8, the radius will be 4, since 4 is one-half of 8. Hope this is helpful!!!
En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor que cada uno de los factores. Es verdadero o falso
Answer:
Falso.
Step-by-step explanation:
Acá tenemos la proposición:
"En una multiplicación, si un factor es un número natural y el otro es un número entero negativo, el producto es siempre menor que cada uno de los factores."
Primero tratemos de demostrar que esto es falso, para ello debemos encontrar un solo ejemplo en el que la proposición sea falsa.
Elijamos al número 1 como el número natural,
Elijamos -10 como el número entero negativo.
El producto es:
1*-10 = -10
Ahora veamos si el producto es menor que cada uno de los factores.
-10 < 1 ?
Si, -10 es menor que 1.
Ahora veamos con el otro factor:
-10 < - 10?
No, un número no puede ser menor que si mismo.
Entonces el producto no siempre es menor que cada uno de los factores.
Entonces la proposición es falsa.

Step-by-step explanation:
x^2 - 9x = x + 24 solve for x
Answer:
x = - 2, x = 12
Step-by-step explanation:
Given
x² - 9x = x + 24 ( subtract x + 24 from both sides )
x² - 10x - 24 = 0 ← in standard form
(x + 2)(x - 12) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
x - 12 = 0 ⇒ x = 12

Answer:
Step-by-step explanation: Area of triangle is base x height divided by 2. So do 8 + 8 to get the base which is 16m. 16 x 8 = 128/2 = 64 m^2
Area of a 1/4 circle is PI Radius ^2 then divided by 4. So [tex]\pi[/tex]*8^2 = 201.06/4 = 50.265 m^2
So to get the area of the entire figure you need to find the perimeter of the figure. So you should use the perimeter formula for each shape and then add all your perimeters of each shape. 1/4 Circle perimeter formula is C=2πr/4 . Perimeter of a square is P = 4a. Perimeter of a triangle is P =
a + b + c . Circle solving 50.27/4 = 12.5675 m^2. Triangle solving 8 + 8 + 16 = 32 m ^2 . Square solving 4 x 8 = 32 m ^ 2 .

Carlos wants to build a circular hot tub with a volume of 1,000 ft3. What is a good approximation for the radius of the tub?
Answer:
6.2 feet
Step-by-step explanation:
we can determine the radius from the volume of the hot tub
volume of a sphere = (4/3) x (n) x (r^3)
n = 22/7
r = radius
1000 = (4/3) x (22/7) x r^3
divide both sides of the equation by (4/3) x (22/7)
238.636 = r^3
find the cube root of both sides
r = 6.20 feet

How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b percent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]

-3>x+16 helllllllp me now i need help plssssss
Answer:
-19 > x
Step-by-step explanation:
Isolate the variable, x. What you do to one side, you do to the other side.
Subtract 16 from both sides:
-3 > x + 16
-3 (-16) > x + 16 (-16)
-3 - 16 > x
-19 > x
-19 > x is your answer.

Step-by-step explanation:
For the triangles to be similar then the ratio of corresponding sides must be equal, that is
[tex]\frac{DF}{XZ}[/tex] = [tex]\frac{EF}{YZ}[/tex] , substitute values
[tex]\frac{2x-5}{22}[/tex] = [tex]\frac{6}{12}[/tex] ( cross- multiply )
12(2x - 5) = 132 ( divide both sides by 12 )
2x - 5 = 11 ( add 5 to both sides )
2x = 16 ( divide both sides by 2 )
x = 8

Sphere A has radius of 2 cm. Sphere B has radius of 4 cm. (=433 V = 4 3 π r 3 use 3.14 for π . ) a) The volume of sphere A is b) The volume of sphere b is c) The volume of Sphere B is_______times greater that the volume of Sphere A.
Answer:
volume of Sphere B is 8 times greater than the volume of Sphere A
Step-by-step explanation:
Sphere A: V = 4π (2^3)/3 = 32π/3
Sphere B: V = 4π (4^3)/3 = 4π(64)/3 = 256π/3
volume of Sphere B / volume of Sphere A = (256π/3)/(32π/3) = 8

-mm-thick piece of graphite? Write your answer in scientific notation.
In response to the question, we may say that In 1.6 micrometres of expression graphite, there are approximately 8,000 layers of graphene.
what is expression ?An expression in mathematics is a collection of representations, numbers, and conglomerates that mimic a statistical correlation or regularity. A real number, a mutable, or a mix of the two can be used as an expression. Mathematical operators include addition, subtraction, fast spread, division, and exponentiation. Expressions are often used in arithmetic, mathematics, and form. They are employed in the depiction of mathematical formulas, the solving of equations, and the simplification of mathematical relationships.
To determine the number of graphene layers in 1.6 micrometres (1.6 m), first convert the thickness of a single layer of graphene from picometers to micrometres:
1 picometer equals 110-6 micrometres
As a result, the thickness of a single sheet of graphene is as follows:
200 picometers = 200 tens of metres = 0.2 tens of metres = 0.2 nanometers = 0.2 tens of micrometres
As a result, the number of graphene layers in 1.6 micrometres is:
8,000 layers = 1.6 micrometres / (0.2 10-3 micrometers/layer)
In 1.6 micrometres of graphite, there are approximately 8,000 layers of graphene.
