The first restaurant is a better deal.
Step-by-step explanation:
First restaurant: Let's say there are 2 people. 28 x 2 = 56. You would have to pay $56 for 2 people.
Second restaurant: Let's say there are 2 people. The graph says that you would have to pay $60 for 2 people.
Therefore, the first restaurant is a better deal.
g Suppose that a large mixing tank initially holds 500 gallons of water in which 50 pounds of salt have been dissolved. Another brine solution is pumped into the tank at a rate of 3 gal/min, and when the solution is well stirred, it is then pumped out at a slower rate of 2 gal/min. If the concentration of the solution entering is 2 lb/gal, determine a differential equation (in lb/min) for the amount of salt A(t) (in lb) in the tank at time t > 0. (Use A for A(t).)
Answer:
the required differential equation is dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
Step-by-step explanation:
Given the data in the question;
A(t) is the mass of the salt in in the tank at time t
the new volume of the solution in the tank increases by one gallon each minute
so
dA/dt = ( Rate in) - ( Rate out)
dA/dt = ( 3 gal/min × 2 lb/gal ) - ( 2 gal/min × [tex]\frac{A}{t+500}[/tex] lb/gal )
dA/dt = 6 - [tex]\frac{2A}{t+500}[/tex]
dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
Therefore, the required differential equation is dA/dt - [tex]\frac{2A}{t+500}[/tex] = 6
A(0) = 50lb
If triangle ACD is similar to triangle ABE, find the value of x?
The value of x and y from the given figure is 2.1 units and 4.5 units.
Given that, triangle ACD is similar to triangle ABE.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
Here, AB=3, AC=5, BE=x, AE=y, ED=3 and CD=3.5
AD=AE+ED
AD=y+3
Now, AB/AC = AE/AD = BE/CD
So, 3/5 = y/(y+3) = x/3.5
⇒ 3/5 = x/3.5
⇒ 3×3.5=5x
⇒ 5x=10.5
⇒ x=10.5
⇒ x=2.1
3/5 = y/(y+3)
⇒3y+9 =5y
⇒2y =9
⇒y =4.5
Therefore, the value of x and y from the given figure is 2.1 units and 4.5 units.

Describe the congruence transformation that maps quadrilateral ABCD to quadrilateral A'B'C'D'.
Question 27 options:
270° counterclockwise rotation
Reflection across the y-axis
90° clockwise rotation
90° counterclockwise rotation
Answer:
90 degree counterclockwise rotation
Step-by-step explanation:
After a 90° counterclockwise rotation, we get the required quadrilateral A'B'C'D'.
Hence the fourth option is correct.
The rotation of axes refers to a transformation in which the coordinate axes in a coordinate system are rotated to form new axes.
When we rotate the quadrilateral ABCD about 90 degrees counterclockwise,
The new position of vertices be,
A ⇒ B'
B ⇒ C'
C ⇒ D'
D ⇒ A'
Hence,
After this rotation, we get the required quadrilateral A'B'C'D' as shown in the figure.
Hence,
After 90° counterclockwise rotation we get such a triangle.

Shereena made the following table she can’t decide if it’s arithmetic or geometric sequence look at the picture bellow and answer the two questions pleaseeeeee
Answer:
Step-by-step explanation:
The characteristic of geometric sequences is that any term divided by the previous term is a constant, called the common ratio. Each term in this sequence is 2 times the previous term. In this case the sequence is an=2(2)^x.
If it were an arithmetic sequence any term subtracted by the previous term would be constant, called the common difference.

1. During a walkathon, Team A walks a total of 6x + 11 miles. Team B walks a total of 2x - 7 miles. What is the difference in miles between the two teams? *
Answer:
(-4x-18) miles
Step-by-step explanation:
Distance walked by team A = (6x + 11) miles
Distance walked by team B = (2x - 7) miles
We need to find the difference in miles between the two teams.
Difference = team B - team A
= (2x - 7)-(6x + 11)
= 2x-6x-7-11
= (-4x-18) miles
So, the difference between the two teams is (-4x-18) miles.

Given parallelogram FGHI determine the missing information
Don’t answer with one answer, blank or ridiculous answer please this is serious
Answer:
y = 3 cm and x = 2.5 cm
Step-by-step explanation:
As we can see it is a parallelogram so
y = 3 cm (being opposite sides of parallelogram)
Now while calculating the diagonal we can use the Pythagoras relation. i.e
perpendicular (p) = 4 cm (IH)
Base (b) = 3 cm (FI)
Hypotenuse (h) = FH = ?
We know by using Pythagoras theorem
h = √ p² + b²
= √ 4² + 3²
= √ 25
= 5 cm
Here we got FH = 5 cm
so the value of x will be 2.5 cm as the diagonal bisects.
Hope it will help :)

A rectangular room is 14 feet by 20 feet. A rectangular rug is placed in the room so that a 2-foot border of floor around the edge of the room is not covered by the rug. What is the area of the rug?
Answer:
the rug should be 10 feet by 16 feet
this makes the area 160 foot squared
Step-by-step explanation:
there is a 2 foot border on each side so the total area loses 4 feet from length. this gives 10 feet by 16 feet.
