Answer:

A = 5.5t + 9

Step-by-step explanation:

We assume that the relationship between t and A is linear.

We have two points on a line: (2, 20) and (4, 31).

We now find the equation of the line.

A = mt + b

m = (31 - 20)/(4 - 2) = 11/2 = 5.5

20 = 5.5(2) + b

20 = 11 + b

b = 9

A = 5.5t + 9

Answer:

Each steak is 72/6 = 12 oz

Step-by-step explanation:

Unit rate = total ounces /  total steaks:

72 ounces / 6 steaks = 12 ounces per steak

Unit rate = 12 ounces per steak.

Answer:

At least means ≥

No more than means ≤

Let x = number of bags of potato chips

Let y = the number of bags of corn chips

x+y≥100

2.50x+2.90y≤$350

Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation

2.50(80)+2.90(20) = 258 which is ≤$350

Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.

Answer:

123

Step-by-step explanation:

[tex]180 - 57 = 123[/tex]

The solution is, the value of m∠6 is 123, i.e. A- 123 °.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

We know that, a ray is a line that continues on forever inn one direction with a point at it's start.

here, we have,

from the given figure we get,

angle 1 is equal to angle 5

as they are corresponding angles,

so, m∠1 =57° = m∠5

now, we have,

that the sum of 5 & 6 is 180

so, they are supplementary angles.

i.e. m∠6 = 180 - m∠5

             =180 - 57

             =123

Hence, The solution is, the value of m∠6 is 123, i.e. A- 123 °.

Answer:

Step-by-step explanation:

Given that the ratio is 1:3

concentrate =1

water=3

the total =3+1=4

using the part to all method

1/4=x/32

cross multiply

4x=32

divide both sides by 4 we have

x=32/4

x=8

Therefore the amount of concentrate is 8 cups

P(A|B) = 1/3

"A Venn diagram in mathematics is a diagram that uses overlapping circles or other shapes to represent the logical relationships between two or more sets of items. "

"For any experiment, a probability denotes the possibility of outcome for any event."

For event A, the probability of event A is,

P(A) = number of favorable outcomes/ total umber of outcomes

"Conditional probability is the probability of an event occurring given that another event has already occurred."

P(A|B) = P(A∩B)÷P(B)

For given diagram:

Let A represents a set of students playing Basketball and B represents a set of students playing Soccer

So, A = {Fran, Ian, Juan, Ella}

⇒ n(A) = 4

B = {Mickey, Marcus, Ella}

⇒ n(B) = 3

(A ∩ B) = {Ella}

⇒ n(A ∩ B) = 1

sample space: S = {Fran, Ian, Juan, Ella, Mickey, Marcus, Mai, Karl, Jada, Gabby}

⇒ n(S) = 10

Now, we calculate probability of B and A∩B.

P(B) = n(B)/n(S)

⇒ P(B) = 3/10

Also, P(A∩B) = n(A∩B) / n(S)

⇒ P(A∩B) = 1/10

So, the required probability would be,

⇒ P(A|B) = P(A∩B) ÷ P(B)

⇒ P(A|B) = (1/10) ÷ (3/10)

⇒ P(A|B) = 1/3

Therefore, P(A|B) = 1/3

Answer:

La desigualdad para determinar el número de empleados a tiempo completo que Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana es 20+40*n ≥ 260. Resolviendo al menos 6 empleados deben trabajar a tiempo completo.

Step-by-step explanation:

Una inecuación es una desigualdad entre letras (incógnitas) y números relacionados por  operaciones aritméticas. Su conjunto solución es el conjunto de números reales que la satisfacen. En una desigualdad, dos expresiones algebraicas están conectadas a través de los signos: mayor que >, menor que <, menor o igual que ≤ y mayor o igual que ≥.

Tom tiene un empleado a tiempo parcial que trabaja 20 horas a la semana. Cada empleado a tiempo completo trabaja 40 horas a la semana. Tom debe programar para que sus empleados trabajen al menos 260 horas a la semana.

Sabiendo que x representa la cantidad de trabajadores a medio tiempo  y n la cantidad de trabajadores a  tiempo completo, entonces  20*x+40*n representa la cantidad de horas que todos los empleados trabajan semanalmente. Si los empleados trabajen al menos 260 horas a la semana, esto significa que la cantidad de horas que todos los empleados trabajan a la semana debe ser mayor o igual a 260 horas. Entonces:

20*x+40*n ≥ 260

Si Tom tiene un empleado a tiempo parcial, entonces la cantidad de trabajadores a medio tiempo x debe tener un valor de 1. Entonces:

20*1+40*n ≥ 260

20+40*n ≥ 260

40*n ≥ 260 -20

40*n ≥ 240

n ≥ 240 ÷40

n ≥ 6

Entonces 6 empleados o más deben trabajar a tiempo completo.

Answer:

Kaya's answer is correct.

Step-by-step explanation:

The number of dots in successive figures are

8, 16, 24.

So Kaya's solution 8n is correct.

When n = 1, first square = 8*1 = 8 dots

n = 2: second square = 8*2 = 16

n = 3, 3rd square = 8*3 = 24.

If I have interpreted Kianna's formula correctly

for n = 1, then the number of dots = 2(1+ 1)^2 - 2(1 - - 1)^2

= 0.

Answer:

55

Step-by-step explanation:

90+35=125. 180-125=55. Answer: 55 degrees.

Answer:

Angle E = B. 55 degrees

Step-by-step explanation:

Every triangle's angles always add up to 180 degrees.

Angle F is marked as a 90 degrees angle, so we can then add 35 and 90 together to get 125.

Then, subtract 125 from 180 to get the measure of Angle E.

180 - 125 = 55

Angle E is measured at: B. 55 degrees.

Given:

The linear equation is

[tex]y=-27x+577[/tex]

where x represents the number of weeks and y represents the amount of money left in Alma's account.

To find:

The number of weeks in which Alma have $145 left in her account.

Solution:

We have,

[tex]y=-27x+577[/tex]

Substitute y=145, we get

[tex]145=-27x+577[/tex]

Subtract both sides by 577.

[tex]145-577=-27x[/tex]

[tex]-432=-27x[/tex]

Divide both sides by -27.

[tex]\dfrac{-432}{-27}=\dfrac{-27x}{-27}[/tex]

[tex]16=x[/tex]

So, the number of required weeks is 16. Therefore, the correct option is B.

Step-by-step explanation: If you look at the base of both triangles, you'll notice that the smaller one has a base of 3, and the bigger one has a base of 6.
