Answer:
-40 °F = -40 °C
Step-by-step explanation:
The formula F = 1.8C + 32 gives the temperature in degrees Fahrenheit (F) for a given temperature in degrees Celsius (C). There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius. Complete the equation you can solve to find that temperature and then use it to find the temperature. Use the variable C to represent the number of degrees Celsius where degrees Fahrenheit and degrees Celsius are the same. The equation is . The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is °C.
F = 1.8 C + 32 (1)
There is one temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius
Then,
F = C (2)
Substitute (2) into (1)
F = 1.8 C + 32 (1)
C = 1.8C + 32
Subtract 1.8C from each side
C – 1.8 C = 32
-0.8C = 32
Divide both sides by -0.8
C = 32 / -0.8
C = -40
Substitute C = -40 into (1)
F = 1.8C + 32 (1)
F = 1.8(-40) + 32
F = -72 + 32
F = -40
Therefore,
The temperature for which the number of degrees Fahrenheit is equal to the number of degrees Celsius is -40
That is,
-40 °F = -40 °C
Para la actuacion del dia de la madre , se colocaron en el patio 40 filas de 32 asientos para cada una. Para la siguiente actuacion,quieren acomodarla mismas cantidad de asientospero esta vez en 64 o en 60 filas ¿como seria la distribucion
Answer:
En 64 filas habrá 51 asientos
en 60 filas habrá 48 asientos
Step-by-step explanation:
Spanish
Primero se averigua la relación entre las filas y los asientos.
40: 32
Dividiendo por 8
5: 4
Usando esta relación podemos encontrar el número de asientos en el número dado de filas.
Si el número de filas es 64 entonces
Asientos de filas
64 x
5 4
Uso de la regla de productos cruzados
x = 64 * 4/5 = 51,2
En 64 filas habrá 51 asientos
Si el número de filas es 60 entonces
Asientos de filas
60 x
5 4
Uso de la regla de productos cruzados
x = 60 * 4/5 = 48
en 60 filas habrá 48 asientos
English
First the ratio of the rows to the seats is found out
40 : 32
Dividing by 8
5: 4
Using this ratio we can find the number of seats in the given number of rows.
If the number of rows is 64 then
Rows seats
64 x
5 4
Using cross product rule
x= 64*4/5= 51.2
In 64 rows there will be 51 seats
If the number of rows is 60 then
Rows seats
60 x
5 4
Using cross product rule
x= 60*4/5= 48
in 60 rows there will be 48 seats

In a store, 9/200 of the shirts are pink and 69/600 are orange. What percent of the shirts are not pink or orange?
Answer:
84%
Step-by-step explanation:
The percentage of pink shirts
= 9/200 × 100%
= 9/2
= 4.5%
The percentage of orange shirts
= 69/600 × 100%
= 69/6
= 11.5%
The percentage of the shirts which are not pink or orange
= 1 - 4.5% - 11.5%
= 84%
Alternative
Find their common denominator.
9/200
= 9×3 / 200×3
= 27/600
The total percentage of shirts in pink and orange
= (27/600 + 69/600) × 100%
= 96/600 × 100%
= 16%
The percentage of the shirts which are not pink or orange
= 1 - 16%
= 84%

Please help, due soon. Use the information provided to write the standard form equation of each circle
Answer:
The answer is D
Step-by-step explanation:
the standard equation for circle is (x －h)² ＋(y －k)² = r² which h is the x coordinate, k is the y coordinate, r is radius. In this case, both x coordinate and y coordinate are 0, so the left side of the equation is x² + y², since the radius is √249, the r² is 249. So the equation is x² + y² = 249, and the answer is D.

The line y=3x creates an acute angle theta when it crosses the x-axis, Find the exact value of sec theta
Answer:
Sec(θ) = 3
Step-by-step explanation:
First, we know that:
Sec(x) = 1/Cos(x)
Now we have an angle θ in the intersection between the line y = 3x and the x-axis.
Here we can think of this as a triangle rectangle, such that:
x is the adjacent cathetus to θ
y is the opposite cathetus to θ
y = 3*x is the hypotenuse.
Here we also need to remember the relation:
Cos(θ) = (adjacent cathetus)/(hypotenuse)
Then we will get:
Cos(θ) = x/(3*x) = 1/3
If we multiply both sides by 3, we get:
Cos(θ)*3 = (1/3)*3 = 1
Cos(θ)*3 = 1
Now we can divide both sides by Cos(θ)
[Cos(θ)*3]/Cos(θ) = 1/Cos(θ)
3 = 1/Cos(θ)
And 1/Cos(θ) = Sec(θ)
Then:
3 = Sec(θ)
The exact value of sec theta is 3.
