-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.

Construct line segmentsConstruct angle bisectors.How to make an inscribed circle in a triangle?There can be many different ways, one can include arc way, one can include angle bisector and perpendicular, and we can even try to discover some. But usually, (for the angle bisector and perpendiculars), we do the following:
Divide one of the angles in half.Divide another angle in half.The incenter, or point where they cross, is the inscribed circle's centre.Construct a perpendicular from the triangle's centre point to one of its sides.Draw an inscribed circle by placing the compass on the centre point and adjusting the length to where the perpendicular crosses the triangle.Drawing random arcs isn't gonna help mostly neither unspecific line segments.

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

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]

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

In rectangle QRST, QS = 5x - 31 and RT = 2x + 11.
Find the lengths of the diagonals of QRST.
A.4
B.6
C.14
D.16
Answer:
C
Step-by-step explanation:
The diagonals of a rectangle are congruent, then
5x - 31 = 2x + 11 ( subtract 2x from both sides )
3x - 31 = 11 ( add 31 to both sides )
3x = 42 ( divide both sides by 3 )
x = 14
Then
RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39
The diagonals are each 39 units

-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.

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 .

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°

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.

Answer:
volume of Sphere B is 8 times greater than the volume of Sphere A
