The sum of three consecutive intergers is 189 what are the integers
Answer:
62, 63, 64
Step-by-step explanation:
The middle integer of three consecutive integers will be the average of them. That is, it will be their sum, divided by 3.
__
The middle integer is 189/3 = 63.
The three consecutive integers are 62, 63, 64.
_____
Additional comment
If you'd like to write an equation that tells you the same thing, let x represent the middle integer. Then the lower one is x-1, and the upper one is x+1. Their sum is ...
(x-1) +x +(x+1) = 189
3x = 189 . . . . . . . . . . . . simplify
x = 189/3 = 63 . . . . . . . divide by the coefficient of x
(x-1) = 63-1 = 62 . . . . . . find the other two integers
(x+1) = 63+1 = 64

The density of iron is 7.8 g/cm3. an iron beam has a volume of 10,504 cm³. what is the mass of the iron beam? enter your answer as a decimal in the box.
Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.
How to determine the mass of the iron beam
Let suppose that the iron beam has an uniform density, the mass of the iron beam (m), in gram, is equal to the product of its density (ρ), in grams per cubic centimeter, and its volume (V), in cubic centimeters:
m = ρ · V (1)
If we know that ρ = 10504 cm³ and V = 7.8 g/cm³, then the mass of the iron beam is:
m = (7.8 g/cm³) · (10504 cm³)
m = 81931.2 g
Under the assumption of uniform iron beam and definition of uniform density, the total mass of the iron beam is equal to 81931.2 grams.

Because you cannot take the square root of a negative number to produce a real solution, then the result will be two conjugate complex numbers (hence the ± sign).
A cube of side 3cm contains a sphere within it.if the sphere touches each face of the cube,find the volume of the space between the cube and the sphere
Answer:
6.86cm^3
Step-by-step explanation:
In order to do this problem you must first find the volume of the cube and subtract the volume of the sphere within it.
Volume of a cube is S^3
using the given 3×3×3= 27cm^3 volume of cube
volume of a sphere is 4/3 pir^3
4/3 × pi x 1.5^3 = 14.14cm^3 volume of sphere
now simply subtract
27-14.14= 6.86 cm^3

28 is the number that appears first for both.
For first sequence:

The elements magnesium (mg) and calcium (ca) play vital roles in maintaining human health, including processes like bone building. the majority of americans have lower levels of magnesium than health experts recommend. do some research in order to propose a possible hypothesis that could explain this phenomenon.
The reason why Americans have lower levels of magnesium than health experts recommend is because of the prevalence of processed food.
What are nutrients?The nutrients in food are those components of food that serve the purpose of nourishing our body. The nutrients present in processed food are different from those present in natural food.
Since many Americans eat a lot of processed instead of natural food, they often lack magnesium which is often absent in processed food.

pls help me find all missing sides and angles. ;-;
Answer:
see explanation
Step-by-step explanation:
the sum of the 3 angles in the triangle = 180° , then
∠ BAC + 51° + 90° = 180°
∠ BAC + 141° = 180° ( subtract 141° from both sides )
∠ BAC = 39°
using the tangent ratio in the right triangle
tan51° = [tex]\frac{opposite}{adjacent }[/tex] = [tex]\frac{AC}{BC}[/tex] = [tex]\frac{AC}{12.8}[/tex] ( multiply both sides by 12.8 )
12.8 × tan51° = AC , then
AC ≈ 15.8 ( to 1 dec. place )
using the cosine ratio in the right triangle
cos51° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{BC}{AB}[/tex] = [tex]\frac{12.8}{AB}[/tex] ( multiply both sides by AB )
AB × cos51° = 12.8 ( divide both sides by cos51° )
AB = [tex]\frac{12.8}{cos51}[/tex] ≈ 20.3 ( to 1 dec. place )
2. What is the new correction equation using the Equal Values Method for the following system below?
y=2x+1
y = 6-3x
Answer:
new equation: 2x +1 = 6 -3x
solution: (x, y) = (1, 3)
Step-by-step explanation:
The Equal Values Method of solving a system of equations has you equate the two expressions that are equal to the same variable or expression. Here, we have two expressions that are equal to y.
equationThe next step is to set them equal to each other:
2x +1 = 6 -3x
__
solutionThis equation can be solved by adding 3x -1 to both sides to get ...
5x = 5
Then dividing both sides by 5 gives ...
x = 1
Substituting into either expression for y gives its value:
y = 2x +1 = 2(1) +1 = 3
The solution to the system is (x, y) = (1, 3).

Which equation is equal to y = 2x + 3 ?
the options are
y + 3 = 2x
y - 3 - 2x = 0
2x + y = 3
y + 2x = -3
The equation y = 2x + 3 is a linear equation, and the equivalent equation of y = 2x + 3 is y - 3 - 2x = 0
How to determine the equal equation?The equation is given as:
y = 2x + 3
Subtract 3 from both sides
y - 3 = 2x
Subtract 2x from both sides
y - 3 - 2x = 0
The above means that the equation y - 3 - 2x = 0 is equal to the equation y = 2x + 3
Hence, the equivalent equation of y = 2x + 3 is y - 3 - 2x = 0
