Robert is painting a portrait. He is using a canvas that has a width of 12 inches and a height of 16 inches. Find the location of a focal point on the portrait using the golden ratio
Answer:
0.56 inches from the vertex of the canvas
Step-by-step explanation:
Golden ratio can be interpreted as
B / A = ( A + B ) / B ----- ( 1 )
A = smaller side = 12 inches
B = larger side = 16 inches
Back to equation 1
16 / 12 = ( 16 + 12 ) / 16
4 / 3 ≠ 7 / 4
The Golden ratio can not be applied because the rule is not obeyed
The focal point can be determined as :
( longest width / 2 )= 12 / 2 = 6^ 2 = 36 ---- 2
(4* depth) = 16 * 4 = 64 ---- 3
hence the focal point ( 2 / 3 ) = 36 / 64 = 0.56 inches from the vertex of the canvas

A produção mensal de uma Olaria é de 5.000 tijolos nesse mês alvará produziu 3925 tijolos quantos tijolos ainda falta para completar a produção mensal
Responda:
1075 tijolos
Explicação passo a passo:
Dado que:
Número de tijolos produzidos Mensalmente = 5.000 tijolos
A quantidade de tijolos produzidos por licença = 3925
O número de tijolos que ainda faltam no valor mensal desejado:
Quantidade de produção mensal - quantidade produzida por licença
5000 - 3925 = 1075 tijolos

Two trains on opposite tracks leave the same station at the same
time. One train travels at an average speed of 80 kilometers per
hour and the other travels at an average speed of 70 kilometers
per hour. How long after they leave the station will they be 50
km apart?
Answer: The answer is 1/3 hour, or 20 minutes
Step-by-step explanation:
The combined rate of separation is (80 km/hr + 70 km/hr) = 150 km/hr,
therefore they will be 1/3 of 150 km apart after traveling 1/3 of an hour.

The Jefferson Valley Bank once had a separate customer waiting line at each teller window, but it now has a single waiting line that feeds the teller windows as vacancies occur. The standard deviation of customer waiting times with the old multiple-line configuration was 1.8 min. Listed below is a simple random sample of waiting times (minutes) with the single waiting line. Use a 0.05 significance level to test the claim that with a single waiting line, the waiting times have a standard deviation less than 1.8 min. What improvement occurred when banks changed from multiple waiting lines to a single waiting line?
Answer:
There will be sufficient evidence to conclude. A further explanation is provided below.
Step-by-step explanation:
The given values are:
[tex]\sigma=1.8[/tex]
[tex]\alpha=0.05[/tex]
[tex]n=10[/tex]
As we know,
[tex]\bar{x}=\frac{\Sigma x_i}{n}[/tex]
[tex]=\frac{71.5}{10}[/tex]
[tex]=7.15[/tex]
The standard deviation will be:
⇒ [tex]s=\sqrt{\frac{1}{n-1} \Sigma(x_i- \bar{x})^2 }[/tex]
On substituting the values, we get
⇒ [tex]=\sqrt{\frac{1}{10-1} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=\sqrt{\frac{1}{9} [(6.5-7.15)^2+...(7.7-7.15)^2]}[/tex]
⇒ [tex]=0.477[/tex]
According to the question,
Hypotheses:
[tex]H_o: \sigma=1.8[/tex]
[tex]H_a: \sigma<1.8[/tex]
The test statistic will be:
⇒ [tex]X^2=\frac{(n-1)s^2}{\sigma^2}[/tex]
⇒ [tex]=\frac{(10-1)\times 0.477^2}{1.8^2}[/tex]
⇒ [tex]=\frac{2.0477}{3.24}[/tex]
⇒ [tex]=0.632[/tex]
Thus the above is the correct response.

As you said, you only need help with no. 2:
a) Check the attachments for the lines
b) The equations are, respectively:
y = -4x + 1 [intersects parabola at 1 point]
Check:
[tex]\begin{bmatrix}y=\left(x-2\right)^2-3\\ y=-4x+1\end{bmatrix}[/tex]
[tex]\begin{bmatrix}-4x+1=\left(x-2\right)^2-3\end{bmatrix}[/tex]
[tex]\begin{bmatrix}-4x+1=x^2-4x+1\end{bmatrix}[/tex]
[tex]x^2=0, x = 0[/tex]
[tex]y=-4\cdot \:0+1 = 1[/tex]
[tex]y=1,\:x=0[/tex]
The point of intersection would be (0, 1)
y = -4x + 3 [intersects parabola at 2 points]
Check:
[tex]\begin{bmatrix}y=\left(x-2\right)^2-3\\ y=-4x+3\end{bmatrix}[/tex]
Subtract the 2 equations,
[tex]y=\left(x-2\right)^2-3\\-\\\underline{y=-4x+3}\\y-y=\left(x-2\right)^2-3-\left(-4x+3\right),\\0=x^2-2\\x = \sqrt{2}, x = - \sqrt{2} \\\\\mathrm{Plug\:the\:solutions\:}x=\sqrt{2},\:x=-\sqrt{2}\mathrm{\:into\:}y=\left(x-2\right)^2-3[/tex]
[tex]\begin{pmatrix}x=\sqrt{2},\:&y=3-4\sqrt{2}\\ x=-\sqrt{2},\:&y=3+4\sqrt{2}\end{pmatrix}[/tex]
Therefore the points of intersection are (√2, 3-4√2) and (-√2, 3+4√2) respectively
And finally we have the equation y = - 4x. It doesn't intersect the parabola.
c) The y-intercepts of such graphs are all less than or equal to 0.
The ordered pair(2,-3) is a solution to which of the following inequalities?
a. y-2x>-5
b. y ≥-2x+2
c. 4y+2x≤-1
d. y<3x-9
Answer:
pretty sure it is 4y+2x<_-1
Answer:
C
Step-by-step explanation:
y-2x>-5 : (2,-3) is not a solution to this equation
y> -2x+2 : (2,-3) is not a solution to this equation
4y+2x< -1 : (2,-3) is a solution to this equation
8. The talent show committee sold a total of 530 tickets in advance. Student
tickets cost $3 each and the adult tickets cost $4 each. If the total receipts were
$1740, how many of each type of ticket were sold?
... please solve this using systems of equations
Answer:
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
Step-by-step explanation:
Let
Number of students tickets sold = x
Number of adults tickets sold = y
x + y = 530 (1)
3x + 4y = 1740 (2)
From (1)
x = 530 - y
Substitute x = 530 - y into (2)
3x + 4y = 1740
3(530 - y) + 4y = 1740
1590 - 3y + 4y = 1740
- 3y + 4y = 1740 - 1590
y = 150
Substitute y = 150 into (1)
x + y = 530
x + 150 = 530
x = 530 - 150
x = 380
Number of students tickets sold = x = 380 tickets
Number of adults tickets sold = y = 150 tickets
carlos es un arquitecto y esta construyendo una casa si ha construido 3/7 de la casa le falta para acabarla es lo mismo que llegar a 7/7
Answer:
Ok, sabemos que Carlos ha construido un 3/7 de una casa.
Queremos saber cuanto le falta para terminar de construirla.
Entonces podemos realizar el cálculo:
1 casa - lo que Carlos ya construyo = Lo que le falta.
Entonces:
1 casa - 3/7 de una casa = X
Podemos reescribir:
1 casa = 7/7 de una casas
así tenemos:
7/7 de una casa - 3/7 de una casa = X
(7/7 - 3/7) de una casa = X
4/7 de una casa = X
Así podemos concluir que a Carlos le falta construir 4/7 de una casa para acabar.

The value of x is 6.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
3x = 4 is an expression.
3x + 4x - 4 is an expression.
We have,
The sum of the measures of angle P and angle S is 140°.
The measure in degrees of angle P is represented by the expression.
= (5x + 30)
The measure of angle S.
= 80°
Now,
5x + 30 + 80 = 140
5x + 110 = 140
Subtract 110 on both sides.
5x = 140 - 110
5x = 30
Divide both sides by 5.
x = 6
Thus,
The value of x is 6.

Find the length of the third side. If necessary, round to the nearest tenth.
Answer:
9.8
Step-by-step explanation:
To solve, use the Pythagorean Theorem: a² + b² = c² or c² - b² = a².
"a" and "b" are both legs of the right triangle. "c" is the hypotenuse. In this case, we need to use this formula: 14² - 10² = a² or 196 - 100 = a². This simplifies to 96 = a². This can simplify further to 9.79795897 = a. Round this to the nearest tenth: 9.8 = a.
