what is emigration?Emigration is the act of leaving one's country or region to live in another. It is a type of migration, which refers to the movement of people from one place to another. Emigration is different from immigration, which is the process of entering a new country or region to live there permanently.
The Puritans were a group of English Protestants in the 16th and 17th centuries who sought to "purify" the Church of England from what they saw as Roman Catholic practices.
They faced persecution and discrimination in England, which led many of them to emigrate to America in search of religious freedom.
The most well-known group of Puritan emigrants to America were the Pilgrims, who established the Plymouth Colony in Massachusetts in 1620.

Jenna and Callie collect stamps. Jenna has 20 less than twice the number of stamps that Callie has. Write an expression that represents the number of stamps that Jenna has.
The expression that represents the number of stamps that Jenna has is 2x - 20
Step-by-step explanation:
Let us revise some algebraic expressions
a is 5 more than b ⇒ a = b + 5a is 3 less than b ⇒ a = b - 3a is twice b ⇒ a = 2 bThe sum of a and b ⇒ a + bThe difference of a and b ⇒ a - bThe quotient of a and b ⇒ a ÷ bThe product of a and b ⇒ a × b∵ Jenna and Callie collect stamps
∵ Jenna has 20 less than twice the number of stamps that Callie has
- Assume that Callie has x stamps, that means to find the number
of stamps of Jenna multiply x by 2 and subtract 20 from the product
∵ Callie has x stamps
∵ Twice means × 2
∴ Jenna has = 2(x) - 20
∴ Jenna has = 2x - 20
The expression that represents the number of stamps that Jenna has is 2x - 20

Find the value of the y-intercept of the line whose equation is 5x - 3y = -12.
To find the y-intercept, rewrite the equation of the line in slope-intercept form:
Slope-intercept form: y = mx + b (b is the y-intercept)
This is how you get your equation in slope-intercept form:
5x -3y = -12
-3y = -5x - 12
-3y/-3 = (-5x -12)/-3
y = (5/3)x + 4

The area of a rectangle is 17 1/2 in and it’s shorter side is 3 1/2in.draw a diagram that shows this information. What is the length of the longer side
Answer: 5
Step-by-step explanation:
17 1/2 is equal to 17.5
3 1/2 is equal to 3.5
Since 17.5 is the area, you must divide by 3.5, which equals 5
To find the length of the longer side of a rectangle with an area of 17 1/2 square inches and a shorter side of 3 1/2 inches, divide the area by the width to get the length. The length of the longer side is 5 inches.
Explanation:The question is asking how to find the length of the longer side of a rectangle given that the area of the rectangle is 17 1/2 square inches and one of the shorter sides is 3 1/2 inches. To find the length of the other side, which we will call length, use the formula for the area of a rectangle which is area = length × width. Since the area and width (shorter side) are known, the equation can be set up as follows:
17 1/2 = length × 3 1/2To find the length, divide the area by the width:Length = (17 1/2) / (3 1/2)Convert mixed numbers to improper fractions:Length = (35/2) / (7/2)Multiply by the reciprocal of the divisor:Length = (35/2) × (2/7)Simplify the fractions:Length = 5Therefore, the length of the longer side of the rectangle is 5 inches.
-4x + y = 4
2x + 2y =13
Answer: What exactly are you asking??
Step-by-step explanation:
Problem 1 Answer: x = -1 + 0.25y
Show Work:
1) Solving
-4x + y = 4
2) Solving for variable 'x'.
3) Move all terms containing x to the left, all other terms to the right.
4) Add '-1y' to each side of the equation.
-4x + y + -1y = 4 + -1y
5) Combine like terms: y + -1y = 0
-4x + 0 = 4 + -1y
-4x = 4 + -1y
6) Divide each side by '-4'.
x = -1 + 0.25y
7) Simplifying
x = -1 + 0.25y
Problem 2 Answer: x = 6.5 + -1y
Show Work:
1) Solving
2x + 2y = 13
2) Solving for variable 'x'.
3) Move all terms containing x to the left, all other terms to the right.
4) Add '-2y' to each side of the equation.
2x + 2y + -2y = 13 + -2y
5) Combine like terms: 2y + -2y = 0
2x + 0 = 13 + -2y
2x = 13 + -2y
6) Divide each side by '2'.
x = 6.5 + -1y
7) Simplifying
x = 6.5 + -1y

What is the exact value of cos (67.5° )?
The exact value of cos(67.5°) is found using half-angle identities in trigonometry, which leads to the solution √(2 - √2)/2.
Explanation:To find the exact value of cos (67.5°), we can use the half-angle identity for cosine which states that cos(θ/2) = ± √ ((1+cosθ)/2). In this case, to find the cosine of 67.5 degrees, we effectively need to calculate the half-angle of 135 degrees.
Thus, cos(67.5°) = cos(135°/2) = √ ((1+cos135°)/2) = √ ((1 - √2/2)/2). This further simplifies to √(2 - √2)/2.
This is because the cosine of 135 degrees equals -√2/2 (as it's in the second quadrant where cosine is negative).
Therefore, the exact value of cos(67.5°) is √(2 - √2)/2.

Dave ordered dinner for a party of 10 people. Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each. what was the average cost of each dinner at Dave's party?
Answer:
The average cost of each dinner at Dave's party is $5.79.
Step-by-step explanation:
Given:
Dave ordered dinner for a party of 10 people.
Three people ordered the $4.75 chicken dinner, two people ordered the $4.95 fish dinner, and five had the beef dinner at a cost of $6.75 each.
Now, to find the average cost of each dinner at Dave's party.
So, we get the total amount for the dinner:
Three people ordered the $4.75 chicken dinner.
[tex]4.75\times 3=14.25[/tex]
Two people ordered the $4.95 fish dinner.
[tex]4.95\times 2=9.90[/tex]
Five had the beef dinner at a cost of $6.75.
[tex]6.75\times 5=33.75[/tex]
Total amount of dinner = [tex]14.25+9.90+33.75=\$57.90.[/tex]
Now, to get the average cost of each dinner of 10 people we divide the total amount of dinner by 10:
[tex]57.90\div 10[/tex]
[tex]=\$5.79.[/tex]
Therefore, the average cost of each dinner at Dave's party is $5.79.
Final answer:
To find the average cost per dinner at Dave's party, calculate the total cost of each type of dinner and sum them up to get the total cost. Then, divide the total cost by the number of guests to obtain the average cost. The average cost per dinner is $5.79.
Explanation:
To calculate the average cost of each dinner at Dave's party, first calculate the total cost of all dinners combined by multiplying the number of each type of dinner by its price and then adding up the totals:
Chicken dinner cost: 3 dinners × $4.75 = $14.25
Fish dinner cost: 2 dinners × $4.95 = $9.90
Beef dinner cost: 5 dinners × $6.75 = $33.75
Next, add all the costs together to get the total cost of the dinners:
Total cost = $14.25 + $9.90 + $33.75 = $57.90
Now, divide the total cost by the number of guests to find the average cost per dinner:
Average cost = Total cost ÷ number of guests
Average cost = $57.90 ÷ 10 = $5.79
So, the average cost per dinner at Dave's party is $5.79.

Two cars are 190 miles apart and travel toward each other along the same road. They meet in 2 hours. One car travels 5 miles per hour faster than the other car. What is the average speed of each car?
The speed of slower car is 45 mph and faster car is 50 mph.
Step-by-step explanation:
Given,
Distance covered by both cars = 190 miles
Time taken by both of them = 2 hours
Let,
x be the speed of slower car.
Speed of faster car = x+5
Combined speed = x+x+5 = 2x+5
We know that;
Distance = Speed * Time

Dividing both sides by 4

Explanation:This is a
problem of relative speed
in
mathematics
. Let's consider the speed of the slower car as 'x' miles per hour. The faster car is travelling 'x+5' miles per hour. Since they are moving towards each other, the sum of their speeds equals the total distance divided by the total time, that is (x + (x + 5)) = 190/2. Simplifying the equation, we get 2x + 5 = 95. Solving further, we get x = 45 miles per hour. Therefore, the slower car is travelling at 45 mph and the faster car is travelling at 50 mph.

Using the Pythagorean Theorem with a hypotenuse of 26 cm and one side of 10 cm, the length of the other side is found to be 24 cm. Thus, the correct answer is (D) 24 cm.
In a right-angled triangle, you can use the Pythagorean Theorem to find the length of the missing side.
