Answer: s=10 b=5 d=8
Step-by-step explanation:Sus tres variables son d, b, s que representan respectivamente el número de Deltas, Betas y Sigmas.
Para configurar el sistema de ecuaciones, sume el número de horas tarea por tarea. La primera ecuación será solo para la cantidad de horas dedicadas a pintar, la segunda para secar y la tercera para pulir.
La primera ecuación: cada modelo tiene una cantidad diferente de horas dedicadas a la pintura. Multiplique esa cantidad de horas por la cantidad de autos de ese modelo (sus variables d, bo c) para obtener la cantidad total de horas dedicadas a pintar todos los autos de ese modelo. Luego, ajústelo al número total de horas que la empresa pasó pintando.
10d + 16b + 8s = 240
Repita para la segunda y tercera ecuaciones y debería obtener:
10d + 16b + 8s = 240
3d + 5b + 2s = 69
2d + 3b + 1s = 41

I am thinking of two numbers.
Sum of these two numbers
is 58, and the difference of these two numbers are b.
What are the two numbers?
What is the answer to this problem?
Answer:
Step-by-step explanation:
Let one number=x
Therefore the othernumber=x+b
Since,
x+x+b=58
==>2x+b=58
==>2x=58-b
==>x=(58-b)/2
Therefore the other number is (58-b)/2 + b

Sketch the graphs. - 2x + 3y = -1
Answer:
Step-by-step explanation:
y =2/3x + 1/3
slope 2/3
y-intercept: (0 ,1/ 3)
Answer:
Step-by-step explanation:
- 2x + 3y = -1 is the equation of a line
Pick any values for x then find y or for y and then find x;
if you have two points you can draw a line trough those two points.
For example,
pick x= -1 then find y
- 2*(-1) + 3y = -1
2+ 3y = -1
3y = -1-2
y= -3/3
y= -1
First point has the coordinates (-1, -1)
pick y = 1 then find x
- 2x + 3*1 = -1
-2x +3 = -1
-2x = -1-3
-2x = -4
x= -4/-2
x= 2
Second point has the coordinate (2, 1)
Draw a line trough the points (-1, -1) and (2,1) to sketch the graph of -2x+3y = -1

A
Answer:
width is 7, length is 14
Step-by-step explanation:
x(x+7) = 98
x^2 + 7x = 98
x^2 + 7x - 98 = 0
( x + 14 )( x - 7 ) = 0
x+14=0 results in negative measures
x-7=0 ---> x= 7

Determine if the leading coefficient of the following function is positive or negative and whether the function has a minimum or maximum vertex point.
Answer:
The function has a negative leading coefficient and a maximum vertex point
Explanation:
This function's leading coefficient is determined by whether it is concave up or concave down, meaning it has an Up and Up end behavior for a positive leading coefficient and a Down and Down end behavior for a negative coefficient.
This function's end behavior is Down and Down, so it must have a negative leading coefficient.
The function has a minimum vertex when the function has a positive leading coefficient and a maximum vertex point when the function has a negative leading coefficient.
This means that the functions vertex is the highest or lowest possible value of the function (the rest of the function continues forever in whichever direction.
This particular function has a maximum vertex as there is no point above the vertex here and the function has a negative leading coefficient.
Answer:
Leading coefficient: negative
Maximum vertex point

Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn (see the
picture below). If the chain does not allow him to go past either of the adjacent sides
of the barn, how much space does Snoopy have to roam?
Use pi = 3.14 and round your answer to the nearest tenth.
Answer:
A = 981.3 ft^2
Step-by-step explanation:
Here we're calculating the area of a semicircle of radius 25 ft.
The area of a circle is A = (pi)(r)^2, and that of a semicircle of the same radius is A = (1/2)(pi)(r)^2.
Here pi = 3.14 and r = 25 ft, and so the area/space in question is
A = (1/2)(3.14)(25)^2
A = 981.3 ft^2
The space does Snoopy have to roam is 490.625 square feet.
Given that, Snoopy the dog is on a 25-ft long chain that is attached to the back of a barn.
What is the area of a sector?The area of a sector is the space inside the section of the circle created by two radii and an arc. It is a fraction of the area of the entire circle.
The formula for the area of the sector of a circle is /360° (r²) where r is the radius of the circle and is the angle of the sector.
From the attached image, we see that snoopy is at the edge of a circle with the garage taking up a quarter of that circle.
Now, the area of space Snoopy was roaming
= 90°/360° × (3.14 × 25²)
= 1/4 × (3.14 × 625)
= 0.25 × 1,962.5
= 490.625 square feet
Therefore, the space does Snoopy have to roam is 490.625 square feet.

Answer:
B 12.5%
Step-by-step explanation:
The percentage change is calculated as ...
% change = ((new value)/(old value) -1) × 100%
= (36/32 -1) × 100% = 1/8 × 100% = 12.5%
