Answer:
There are 7456 seats on the lower level and there are 5044 seats on the middle level.
Step-by-step explanation:
Let 'X" be the number of seats on the upper level. Then we can find how many seats are on the lower level by solving the following equation...
# of seats on the lower level = 3x - 50
# of seats on the lower level = 3(2502) - 50
# of seats on the lower level = 7456
Now we just make the equation for the number of seats on the middle level, and so we get...
# of seats on the middle level = 2x + 40
# of seats on the middle level = 2(2502) + 40
# of seats on the middle level = 5044

Answer:
-3 1/8
Step-by-step explanation:
This can be done by setting up the following equation. (I'm going to convert 1/4 to .25 to make things easier)
-1.25/1 = x/2.5
x = -3.125 or -3 1/8
please hurry and answer 55 + 7a = 19
Answer:
a = -36/7
Step-by-step explanation:
55 + 7a = 19
(55 - 55) + 7a = (19 - 55)
7a = -36
7a/7 = -36/7
a = -36/7 the fraction can't be simplified any further

Use the formula Circumference = 2 X A X radius, where it is approximately 3.14, to answer the question.
5.0 inches
What is the approximate circumference of the circle?
O A 7.9 inches
OB. 15.7 inches
OC 31.4 inches
OD. 62.8 inches
HELPPP IM TIMED
Answer:
A
Step-by-step explanation:
You divide the diameter by 2 to get radius. So 5÷2=2.5
So then you multiply 2.5 by pi aka 3.14 so 2.5x3.14=7.85 So we rounds 7.85 to 7.9
Answer:
B. 15.7
Step-by-step explanation:
Circumference= 2×π×r
2×3.14×2.5 (half of 5 is 2.5)
=15.7

solve for x 3 (x + 5) = 9
Answer:
- 2
Step-by-step explanation:
3 ( x + 5 ) = 9
x + 5 = 9 / 3
x + 5 = 3
x = 3 - 5
x = - 2
Answer:
x = - 2
Step-by-step explanation:
Given
3(x + 5) = 9 ← divide both sides by 3
x + 5 = 3 ( subtract 5 from both sides )
x = - 2

Choose the graph that represents the following system of inequalities:
y ≤ −3x + 1
y ≤ 1 over 2x + 3
In each graph, the area for f(x) is shaded and labeled A, the area for g(x) is shaded and labeled B, and the area where they have shading in common is labeled AB.
Graph of two intersecting lines. Both lines are solid. One line f of x passes through points negative 2, 2 and 0, 3 and is shaded above the line. The other line g of x passes through points 0, 1 and 1, negative 2 and is shaded above the line.

9514 1404 393
Answer:
C
Step-by-step explanation:
Both inequalities have y ≤ ( ), so will be bounded by solid lines, and shaded below that line (where y-values are lower). The first inequality has a boundary line with a steeply negative slope; the second has a shallow positive slope.
Since both are shaded below, the doubly-shaded area (AB) will be in the bottom quadrant, below the point of intersection of the lines. The graph attached below shows the correct shading.

you have 11 art projects that weigh 24 pounds. If you give you mom 7 of your art projects, how much would her box weigh?
The weight for mom's boxes is obtained as 41.41 pounds.
What is weight?
Weight gauges how much gravity is pulling on a body.
The weight formula is provided by -
w = mg
Since weight is a force, it has the same SI unit as a force, which is the Newton (N).
Use a proportion to solve this problem.
Since the weight of the art projects is directly proportional to the number of art projects, we can set up the following proportion -
weight of 11 art projects / 11 = total weight / 24
Solving for the total weight -
total weight = (weight of 11 art projects / 11) x 24
total weight = 2.18 x 24
total weight = 52.32 pounds
So the total weight of the 11 art projects is 24 pounds, and if mom gets 7 of them, 4 art projects will be left weighing a total of -
weight of 4 art projects = (weight of 11 art projects - weight of 7 art projects)
weight of 4 art projects = (24 - (7/11) x 24)
weight of 4 art projects = 10.91 pounds
So, mom would be receiving 7 art projects weighing a total of -
weight of 7 art projects = (total weight - weight of 4 art projects)
weight of 7 art projects = (52.32 - 10.91)
weight of 7 art projects = 41.41 pounds
Therefore, mom's box would weigh 41.41 pounds.

There are 240 girls at the park. There are 360 more boys than girls at the park.How many boys are at the park?
Answer:
600 boys
Step-by-step explanation:
To find how many boys are at the park, add 360 to 240:
240 + 360
= 600
So, there are 600 boys at the park
Answer:
There are 600 boys at the park.
Step-by-step explanation:
The information we know is that there are already 240 girls at the park, and we also know that there are 360 more boys than girls. So to find out how many boys there are we must add the two values together, 240 and 360.
240 + 360 = 600
So that means there are 600 boys at the park.

what is the equation of the line that passes through (6,5) and (-7,4)
Answer:
y = 1/13 + 59/13
Step-by-step explanation:
y2 - y1 / x2 - x1
4 - 5 / -7 - 6
-1 / -13
1/13
y = 1/13x + b
4 = 1/13(-7) + b
4 = -7/13 + b
59/13 = b
y = 1/13 + 59/13
(a + b)(a - b) = a^2 - b^2
1. Multiply the numerator and the denominator by the complex conjugate of the denominator.
2. Simplify the results into the real part and the imaginary part.
Divide the complex numbers. Show all work.
Answer:
Step-by-step explanation:
hello : given z = (-6-10i)/(4+7i)
the complex conjugate of the denominator is : 4-7i
1. Multiply the numerator and the denominator by the complex conjugate of the denominator: z = (-6-10i)(4-7i)/(4+7i)(4-7i)
use identity : (a + b)(a - b) = a² - b² calculate the product : (4+7i)(4-7i)
(4+7i)(4-7i) = 4² -(7i)² =16 -49i² =16+49 = 65..... ( i² = -1)
2) Simplify the results calculate the numerator : (-6-10i)(4-7i)
(-6-10i)(4-7i) = -24+42i -40i+70i² = -24+42i -40i-70 .....( i² = -1)
(-6-10i)(4-7i) = -94+2i
now : z = (-94+2i )/65 = (-94/65) +(2/65) i
the real part is : ( -94/65) and the imaginary part is : 2/65

Para reunir dinero para su gira de estudios , los alumnos de un curso deciden vender números de una rifa que se encuentran numeradas del 1 al 100 ¿Cual es la probabilidad de ganar en la rifa si se compran todos los numeros que sean multiplos de 3 o de 5?
Respuesta:
0.53
Explicación:
Para calcular la posibilidad del evento A: "ganar la rifa comprando todos los números múltiplos de 3 o 5", debemos usar la siguiente fórmula.
P(A) = casos favorables / casos posibles
Evaluemos primero todos los casos que son múltiplos de 3, entre 1 y 100: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 48, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99. En total son 33.
Ahora, evaluemos todos los casos que son múltiplos de 3, entre 1 y 100: 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100. En total son 20.
El número total de casos favorables es 33 + 20 = 53.
El número de casos posibles es el total de números de 1 a 100, es decir 100.
Luego P(A) = 53/100 = 0.53.
