Answer:

Starting time = 11:43 pm last night

Step-by-step explanation:

The time that her train started from the station is as follows

Given that

Grandparents reached the place at 9:20AM

A concession stand sold ice cream cones, salted pretzels, and tacos at a basketball game. Ice cream cones were sold for $3.00, s
WITCHER [35]

Answer:

51 salted pretzels were sold.

Step-by-step explanation:

<u>Step 1: Write the data</u>

Number of Ice cream cones sold: x

Cost of ice cream cones sold: 3x

Number of Salted pretzels sold: y

Cost of salted pretzels sold: 2.5y

Number of tacos sold: z

Cost of tacos sold: 2z

<u>Step 1: Make equation 1</u>

Total money made: $359.5

Money made from tacos: $70

Money made from ice cream cones and salted pretzels: 359.5-70 = $289.5

<em>Equation 1:</em>

3x + 2.5y = 289.5

<u>Step 3: Make equation 2</u>

Cost per tacos: $2

Total number of tacos sold: z

Money made from total tacos: $70

2z = 70

z = 35 tacos were sold

Total number of ice cream cones and salted pretzels sold: 140-35 = 105

<em>Equation 2: </em>

x + y = 105

<u>Step 4: Find the unknown value by substitution</u>

3x + 2.5y = 289.5

x + y = 105

<em>Find x in terms of y from equation 2</em>

x + y = 105

x = 105 - y

<em>Substitute x in equation 1</em>

3x + 2.5y = 289.5

3(105-y) + 2.5y = 289.5

315 - 3y + 2.5y = 289.5

0.5y = 25.5

y = 51

y represents the number of salted pretzels sold. Therefore, 51 salted pretzels were sold.

As you missed to add the diagram. After a little research, I was able to find the diagram, and hence, I am answering based on that diagram which anyways would clear your concepts. Diagram is also attached below.

Answer:

q ∧ p represents the region B.

Step-by-step explanation:

From the attached diagram, it is clear that

  • the region B includes the area which commonly lies both in p AND q at the same time.
  • In other words, B displays the region in which both p AND q are true.

Here is the truth table

<h3>p          q          q ∧ p</h3>

T           T             T <em>   </em>

T            F            F

F            T            F

F            F            F

Therefore, q ∧ p represents the region B.
