a surveyor is surveying a street. The surveyor is standing at point P looking down the street a No parking sign at Point P given PA=3x-4, PR=21 meters, AR=7 meters and point A is between point R and point p
Answer:
6
Step-by-step explanation:
Pa = 3x-4. Pr = pa+ar
Ar = 7
3x-4+7= 21
Combine light terms
Then order of operations
3x-3=21
3x-18
X=6
The required value of x is 6
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign =.
Now it is given that,
PA = 3x-4
PR = 21 meters
AR=7 meters
Since point A is between point R and point P.
Thus we can write,
PR = PA + AR
Put the values of PA,PR and AR we get,
21 = 3x - 4 + 7
Subtracting 7 both the side we get,
3x - 4 = 14
Adding 4 both the side we get,
3x = 18
Dividing both side by 3 we get,
x = 6
which is the required value of x.
Thus, the required value of x is 6.

Chocolate ganache is made from chocolate and cream in a3:2 ratio, respectively. If one batch of ganache requires 240 grams of chocolate, how many grams of cream is required?
Answer:
160 grams
Step-by-step explanation:
Since one batch of ganache needs 240 grams of chocolate, you divide 240 by 3, since the ratio is 3:2.
240÷3x= 80.
Now that you have x, multiply x by 2.
80*2= 160

Answer:
Both angles B and C are equal to 40°
Step-by-step explanation:
The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.
[tex]2x+10=3x-5\\10=x-5\\15=x[/tex]
Now we are going to plug x back into each expression to solve for angles B and C.
Angle B
[tex]2x+10[/tex] ⇒ [tex]2(15)+10=40[/tex]
Angle C
[tex]3x-5[/tex] ⇒ [tex]3(15)-5=40[/tex]
Both angles B and C are equal to 40°

Andrés tiene una cuerda de 120 metros y otra de 96 metros. Desea cortarlas de modo que todos los trozos sean iguales pero lo más largos posible. ¿Cuántos trozos de cuerda obtendrá?
Answer:
Se obtendrá 9 trozos de cuerda.
Step-by-step explanation:
Para que sea cada trozo de igual extensión, pero lo más posible, se tiene que encontrar el máximo común divisor de 96 y 120 para determinar la longitud máxima del trozo. Se realiza el siguiente procedimiento para determinar el máximo común divisor:
1) Se determina cada número como producto de números primos:
[tex]96 = 2^{5}\times 3[/tex]
[tex]120 = 2^{3}\times 3 \times 5[/tex]
2) Se determina los números primos comunes de cada número y se multiplican entre sí:
[tex]x = 2^{3}\times 3[/tex]
[tex]x = 8\times 3[/tex]
[tex]x = 24\,m[/tex]
Cada trozo debe ser de 24 metros de longitud.
Ahora se determina el número de trozos al dividir la longitud total por el resultado anterior:
[tex]n = \frac{120\,m+96\,m}{24\,m}[/tex]
[tex]n = 9[/tex]
Se obtendrá 9 trozos de cuerda.

Evaluate the following function over the domain {0,1,2,3}. What is the range?
Answer:Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis.
range is The zero doesn't matter. You still subtract the lowest number from the highest. If zero is the lowest number, then the highest number is the range. If the set consists of negative numbers, and zero is the highest number, then the lowest number (without its negative sign) is the range.

An airport offers 2 shuttles that run on different schedules. If both shuttles leave the airport at 4.00 pm at what time will they leave the airport together
Answer:
4:18 pm
Step-by-step explanation:
An airport offers 2 shuttles that run on different schedules.If both shuttles leave the airport at 4:00 p.m.,at what time will they next leave theairport together.
Shuttle A leaves every 6 minutes
Shuttle B leaves every 9 minutes
Solution
To solve for when next both shuttles will leave the airport together, find the least common multiples of 6 minutes and 9 minutes
Shuttle A (every 6 minutes) = 6, 12, 18, 24
Shuttle B (every 9 minutes) = 9, 18, 27, 36
The least common multiples of 6 minutes and 9 minutes is 18 minutes
4:00 pm + 18 minutes
= 4:18 pm
The next time both shuttles will leave theairport together is 4:18 pm of the same day

The formula D =3/2 (100 – C) relates D,
the temperature measured on the Delisle
scale, in degrees, and C, the temperature
measured on the Celsius scale, also in
degrees. What is the temperature in
degrees Celsius when the temperature in
degrees Delisle is 78°?
BO
Answer:33
Step-by-step explanation:
3/2 —> 1.5
1.5(100-C) C is 78°
1.5(100-78)
1.5(22)
33
The temperature in degrees Celsius, if the function of the relationship is given as 78 = 3/2(100 - C), is calculated as: C = 48
What is Function?A function is a form of equation that relates one quantity that changes with another.
Given the formula for the function representing the relationship between D and C as, D = 3/2(100 - C), to find the temperature in degrees Celsius when the D = 78, substitute D = 78 into D = 3/2(100 - C).
78 = 3/2(100 - C)
(2)(78) = 3(100 - C)
156 = 3(100 - C)
156/3 = 100 - C
52 = 100 - C
52 - 100 = -C
-48 = -C
C = 48

You roll a single die numbered from 1 to 6 twice. The probability of rolling an even number the first time and a 6 the second is the setup. What is the probability "rolling an even number the first time"? (Answer in percentage)
Answer:
The answer is 50%Step-by-step explanation:
step one :
first and foremost we are going to list the sample space related to a die
the same space is S= {1,2,3,4,5,6}= 6
step two:
now the even numbers in the sample space are ={2,4,6}= 3
hence we can solve for the probability of obtaining an even number to be
Pr(even number)= 3/6= 1/2.
step three:
since we are to provide the answer in percentage format, we can easily do this by multiplying the answer by 100 to get the percentage
(1/2)*100= 0.5*100= 50%

In the diagram JL = 120, What are JK and KL? Explain how you found your answer.
Answer:
JK = 42
KL = 78
Step-by-step explanation:
To find the lengths of JK and KL, we need to first find the value of x. We know that the length of the entire line is 120. That means we need to add the lengths of JK and JL and set it equal to 120.
4x+6+7x+15 = 120
Combine like terms.
11x+21 =120
Subtract 21 from each side.
11x= 99
Divide both sides by 11.
x=9
Now that we know the value of x, we simply plug it into the equations to find out the lengths of each line segment.
JK = 4x+6
4(9)+6 (x is plugged in)
36+6 = 42
JK=42
Now lets do KL.
7x+15
7(9)+15
63+15 = 78
KL = 78
The values of JK = 42 and KL= 78.
What is a Line Segment?A line segment is defined as a measured path between two places. Line segments can make up any polygon's sides because they have a set length.
The figure given below shows a line segment JL , where the length of line segment JL refers to the distance between its endpoints, J and L.
Given that JL = 120,
And JK = 4x + 6 and KL= 7x + 15
J_________K______________L
⇒ JL = JK + KL
⇒ 120 = 4x + 6 + 7x + 15
⇒ 120 = 11x + 21
⇒ 11x = 99
⇒ x = 9
Substitute the values of x = 9 in the JK = 4x + 6 and KL= 7x + 15,
JK = 4(9) + 6 = 42
KL= 7(9) + 15 = 78
Hence, the values of JK = 42 and KL= 78 .
