Step-by-step explanation:
Can sombody please help me solve this: x + 14 = 7x + 32 – 3x
x+14 = 7x+32-3x
x+14 = 4x+32
-x -x
14 = 3x+32
-32 -32
-18 = 3x
/3 /3
-6 = x
x = -6
Answer:
x=-6
Step-by-step explanation:
x+14=7x+32-3x
x+14=7x-3x+32 group like terms
x+14=4x+32 add similar element
x+14-14=4x+32-14 subtract 14 from both sides
x=4x+18 simplify
x-4x=4x+18-4x subtract 4 from both sides
-3x=18
then divide both sides by 3
and then simplify
then u get x=-6

bought?
b) How much more copper wire than
iron wire did he buy?
can u send me the question once more correctly so that I can help u
My username is Ayaan707.

Answer:
Total length of wire bought = 2 1/4 + 3 1/3
=9/4 + 10/3
=9*3/4*3 + 10*4/3*4 (LCM)
= 27/12 + 40/12
=67/12= 5 7/12metre is the answer

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

Item 12
SA−→ bisects ∠RST and m∠RST=54.2∘. Find m∠RSA and m∠AST.
Answer:
m∠RSA is 27.1° and m∠AST is 27.1°
Step-by-step explanation:
If a ray bisects an angle, then it divides it into two equal angles in measures and the measure of each one is half the measure of this angle
In the given question
∵ Ray SA bisects ∠RST
→ That means it divides it into two angles RSA and AST
∴ m∠RSA = m∠AST = [tex]\frac{1}{2}[/tex] m∠RST
∵ m∠RST = 54.2°
→ Multiply its measure by to find the measures its parts
∴ m∠RSA = [tex]\frac{1}{2}[/tex] × 54.2°
∴ m∠RSA = 27.1°
∴ m∠AST = [tex]\frac{1}{2}[/tex] × 54.2°
∴ m∠AST = 27.1°

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%.

Answer:
2nd option
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°
Q. Mary lost 30 pounds. Before her diet she weighed 180 pounds. What is the
percent of change?
Answer:
16.67%
Step-by-step explanation:
A fraction consists of two numbers and a fraction bar:
30/180
The number above the bar is the numerator: 30
The number below the bar is the denominator: 180
Divide the numerator by the denominator to get fraction's value:
Val = 30 ÷ 180
30/180=16.666666667
16.666666667= 16.67%

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)

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
