Answer:
real, natural, integers, rational: 2, 3irrational: √2, √3use the distributive propertyStep-by-step explanation:
A) Any positive integer is all of real, natural, integer, and rational. A couple of examples of positive integers are 2, and 3.
Any non-complex number is real: -98.6, +29.7π.
Natural numbers are positive integers: 89, 10103.
Integers are any positive or negative number that has no fractional part. Zero is also an integer. A couple are -3, 0.
A rational number is one that can be expressed as the ratio of two integers. Any finite decimal number and any repeating decimal number are rational numbers. A couple of these are 22/7 and -0.0037285.
An irrational number is a number that cannot be expressed as the ratio of two integers. A cube root of a number that is not a perfect cube will be irrational, for example, The same is true of other roots. √2, ∛-5 are irrational. Pi (π) is a famous irrational number, along with 'e', the base of natural logarithms.

B) The terms inside parentheses are unlike, so cannot be combined. The only way this expression can be simplified is by removing the parentheses using the distributive property.
-5(2x -3y +6z -10) = (-5)(2x) +(-5)(-3y) +(-5)(6z) +(-5)(-10)
= -10x +15y -30z +50

A square and an equilateral triangle have the same perimeter. Each side of the triangle is 3 inches longer than each side of the square. What is the perimeter of the square?
ASAP I ONLY HAVE 15 MINUTES
Answer:
36 inches
Step-by-step explanation:
Q = length of the sqaure
T = length of the triangle
Equation 1: 4Q = 3T
Equation 2: T = 3+Q;
Then, subsitute T=3+Q into equation 1:
4Q = 3(3+Q)
4Q = 9 + 3Q
Q = 9
-----
Each side of the square is 9 inches, so the perimeter will be 9X4 = 36inches

A study investigated about 3000 meals ordered from Chipotle restaurants using the online site Grubhub. Researchers calculated the sodium content (in milligrams) for each order based on Chipotle's published nutrition information. The distribution of sodium content is approximately Normal with mean 2000 mg and standard deviation 500 mg. About what percent of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium?
Answer:
21.186%
Step-by-step explanation:
z = (x-μ)/σ,
where
x is the raw score = 2400mg
μ is the population mean = 2000mg
σ is the population standard deviation = 500mg
z = 2400 - 2000/500
z = 0.8
Probability value from Z-Table:
P(x<2400) = 0.78814
P(x>2400) = 1 - P(x<2400) = 0.21186
Converting to percentage:
0.21186 × 100
= 21.186%
Therefore, the percent of the meals
ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%
21.186% of the meals ordered exceeded the recommended daily allowance of 2400 mg of sodium.
It is known that 3000 meals ordered from Chipotle restaurants using the online site Grubhub.
And the distribution of sodium content is approximately Normal with mean 2000mg and standard deviation 500 mg.
We know,
[tex]z = \frac{(x- \mu)}{\(\sigma\)}[/tex],
And daily allowance of 2400 mg of sodium
x is the raw score = 2400mg
μ is the population mean = 2000mg
σ is the population standard deviation = 500mg
[tex]z = \frac{2400 - 2000}{500}[/tex]
z = 0.8
Probability value from Z-Table:
[tex]P(x<2400) = 0.78814\\P(x>2400) = 1 - P(x<2400) \\= 0.21186[/tex]
Converting to percentage:
[tex]= 0.21186 (100)\\= 21.186%[/tex]
Therefore, the percent of the meals ordered that exceeded the recommended daily allowance of 2400 mg of sodium is 21.186%.

Solve the following equation by completing the square.
A.
B.
C.
D.
Answer:
x = 2 + sqrt(2) or x = 2 - sqrt(2) thus B. is your answer
Step-by-step explanation:
Solve for x over the real numbers:
4 x^2 - 16 x + 8 = 0
Hint: | Write the quadratic equation in standard form.
Divide both sides by 4:
x^2 - 4 x + 2 = 0
Hint: | Solve the quadratic equation by completing the square.
Subtract 2 from both sides:
x^2 - 4 x = -2
Hint: | Take one half of the coefficient of x and square it, then add it to both sides.
Add 4 to both sides:
x^2 - 4 x + 4 = 2
Hint: | Factor the left-hand side.
Write the left-hand side as a square:
(x - 2)^2 = 2
Hint: | Eliminate the exponent on the left-hand side.
Take the square root of both sides:
x - 2 = sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the first equation: Solve for x.
Add 2 to both sides:
x = 2 + sqrt(2) or x - 2 = -sqrt(2)
Hint: | Look at the second equation: Solve for x.
Add 2 to both sides:
Answer: x = 2 + sqrt(2) or x = 2 - sqrt(2)

Step-by-step explanation:
Rachel is building a fence around her yard. She wants to create a square area that will have an area of 150 m. If the fencing has been cut into 1m lengths, how much fencing will Rachel need?
Answer:
Rachel will need 49 meters of fencing.
Step-by-step explanation:
From Geometry we know that area of the square ([tex]A[/tex]), measured in square meters, is represented by the following formula:
[tex]A = l^{2}[/tex] (Eq. 1)
Where [tex]l[/tex] is the side length of the square, measured in meters.
The length of the square is now cleared:
[tex]l = \sqrt{A}[/tex]
If we know that [tex]A = 150\,m^{2}[/tex], then the side length is:
[tex]l =\sqrt{150\,m^{2}}[/tex]
[tex]l \approx 12.247\,m[/tex]
The total amount of fencing is equal to the perimeter of the square ([tex]p[/tex]), measured in meters, that is:
[tex]p = 4\cdot l[/tex] (Eq. 2)
If we know that [tex]l = 12.247\,m[/tex], then the perimeter of the square is:
[tex]p = 4\cdot (12.247\,m)[/tex]
[tex]p = 48.988\,m[/tex]
As fencing is cut into 1-m lengths, we need to round this number up to the nearest integer. That is:
[tex]p = 49\,m[/tex]
Rachel will need 49 meters of fencing.

Step-by-step explanation:
the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
121.8° is an exterior angle of the lower triangle , then
∠ 2 + 17.3° = 121.8° ( subtract 17.3° from both sides )
∠ 2 = 104.5°
------------------------------------
∠ 2 is an exterior angle of the upper triangle , then
∠ 1 + 37.1° = 104.5° ( subtract 37.1° from both sides )
∠ 1 = 67.4°

Um monumento na cidade de São Paulo, foi construído seguindo a forma de um tronco de pirâmide de bases quadradas. Seu volume é de 21000 m³ e sua altura é de 30 m. Sabendo que sua base maior tem aresta medindo 40 m, calcule a medida da aresta da sua base menor.
Responda:
15cm
Explicação passo a passo:
Volume de uma pirâmide = Área da Base × Altura / 3
Dado
Volume = 2100m³
Altura da pirâmide = 30m
Vamos obter a área base primeiro, substituindo o valor dado na fórmula.
2100 = B (30) / 3
2100 = 30B / 3
2100 = 10B
10B = 2100
Divida os dois lados por 10
10B / 10 = 2100/10
B = 210cm²
Como a base é um quadrado
área da base quadrada = 210cm²
L² = 210
L = √210
L = 14,49cm
C ≈ 15cm
Portanto, a medida da borda de sua menor base é de aproximadamente 15 cm
