What is Division method?Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
Tasha hands out 5 note cards to each student in the class.
And, She hands out all of the 145 note cards contained in the package.
Here, 145 note cards contained in the package.
And, Tasha hands out 5 note cards to each student in the class.
Hence, Number of students = 145 / 5

Starting at time t = 0, the altitude of one helicopter is given by A1 = 600 + 150t, and the altitude of a second helicopter is given by A2 = 1250 + 50t. Which equation represents the difference of their altitudes A at time t?
Answer:
The equation for difference in altitude of the two helicopters is A = 650 - 100t
Step-by-step explanation:
Given;
The altitude of one helicopter is, A1 = 600 + 150t
The altitude of a second helicopter is, A2 = 1250 + 50t
Their difference in altitude, A at time t, is calculated as
A₂ - A₁ = A = (1250 + 50t) - (600 + 150t)
A₂ - A₁ = A = 1250 + 50t - 600 -150t
A₂ - A₁ = A = 1250 - 600 + 50t - 150t
A₂ - A₁ = A = 650 - 100t
Therefore, the equation for difference in altitude of the two helicopters is A = 650 - 100t

A land bridge from Asia to the Americas was made possible by which of the following?
A) archaeologists
B) the development of stone tools
C) last Ice Age
D) prehistoric people
Answer:
C, Last Ice Age
Step-by-step explanation:
A land bridge wouldn't be developed by humans. The only reasonable explanation would be the last Ice Age
A land bridge from Asia to the Americas was made possible by the last Ice Age. So, the correct answer is C.
What is Land Bridge?A land bridge is an isthmus or wider land connection between otherwise separate areas, over which animals and plants are able to cross and colonize new lands.
A land bridge from Asia to the Americas was made possible by the last Ice Age.
During the last Ice Age, much of the Earth's water was locked up in glaciers, causing sea levels to drop and exposing a land bridge between Asia and North America.
This allowed prehistoric people to migrate from Asia to the Americas, a journey that would not have been possible without the land bridge created by the last Ice Age.
Hence, A land bridge from Asia to the Americas was made possible by the last Ice Age. So, the correct answer is C.

Answer:

Step-by-step explanation:
Given 2 secants from a point outside the circle.
Then the product of the external part and the entire secant of one secant is equal to the product of the external part and the entire secant of the other secant, that is
(x + 1)(x + 1 + 11) = (x + 4)(x + 4 + 1)
(x + 1)(x + 12) = (x + 4)(x + 5) ← expand both sides
x² + 13x + 12 = x² + 9x + 20 ← subtract x² + 9x from both sides
4x + 12 = 20 ( subtract 12 from both sides )
4x = 8 ( divide both sides by 4 )

Answer: The area is 103.5
Step-by-step explanation: The question becomes very simple once you know how to split this object into objects that you most likely know how to solve the area of. In truth, if you split the shapes in triangles and rectangles, you would find 4 rectangles and a triangles. Once you have solved the area of all of them, you would just have to add. How I solved it goes like this. I added 22.5 as the triangle, 35 as a rectangle, 2 as another rectangle, 18 as another rectangle, and 26 as the final rectangle.(take note that these numbers are the areas of the split shapes) If you added correctly, you would get 103.5

Caelan has $7,500 in an account that earns 3.2% interest compounded annually. If she doesn't touch the money, how much will it be worth after 5 years?
Answer:
It'll be worth approximately $8779.3 after 5 years.
Step-by-step explanation:
Since it's compounded we need to use the appropriate formula to solve this problem, which is shown below:
M = C*(1 + r)^t
Where M is the final amount, r is the interest rate and t is the time elapsed in years. Applying the data from the problem we have:
M = 7500*(1 + 0.032)^5
M = 7500*(1.032)^5
M = 8779.2971
It'll be worth approximately $8779.3 after 5 years.

As of 2008 the worlds population was about 6.7 billion people. The population of the United States in 2008 was 305 million. In 2008 what percent of the world’s population was the US population?
Answer:
In 2008 the US population was 4.55% of the world population.
Step-by-step explanation:
In order to calculate the percent of the world population that represents the US population, we can apply a rule of three in such a way that the world population is related to 100% in the same proportion that the US population is related to x%. We then solve for x. This is shown below:
6.7*10^9 -> 100%
305*10^6 -> x%
6.7*10^9 / 305*10 ^6 = 100 / x
6.7*10^3 / 305 = 100 / x
(6.7*10^3)*x = 305*100
x = 30500 / (6.7*10^3)
x = 4,55 %
In 2008 the US population was 4.55% of the world population.

Which binomial is a factor of the quadratic trinomial x2 − 7x + 12? A. (x + 2) B. (x − 6) C. (x + 3) D. (x − 4)
Answer:
D
Step-by-step explanation:
To factor a quadratic you need to think about what adds up to the b coefficient (the number in front of b) and multiplies to the constant. 3 and 4 do these, but you also know that you have -7 instead of positive 7. A negative times a negative is equal to a positive, which you can do (x-3)(x-4) to equal your quadratic trinomial.
Solve the following system of equations.
x-2y = 10
y = -6x +34
I have 9 more questions so please answer all
I have 9 more please answer all
Answer:
x = 6, y = -2
Step-by-step explanation:
x-2y = 10
y = -6x +34
Substitute the second equation into the first for y
x - 2(-6x+34) = 10
Distribute
x +12x - 68 = 10
Combine like terms
13x -68 = 10
Add 68 to each side
13x - 68+68 = 10+68
13x = 78
Divide each side by 13
13x/13 = 78/13
x = 6
Now find y
y = -6x+34
y = -6(6)+34
y = -36+34
=-2
Answer:
x = 6 y = -2
Step-by-step explanation:
x-2y = 10
x = 10 + 2y
y = -6x +34
y = -6(10 + 2y) + 34
y = -60 - 12y + 34
13y = -26
y = -2
x = 10 + 2(-2)
x = 10 - 4
x = 6
Which function has two x-intercepts, one at (0,0) and one at (4,0)?
Of(x) = x(x - 4)
O f(x) = x(x + 4)
O f(x) = (x - 4)(x-4)
Of(x) = (x + 4)(x + 4)
Answer:
1st equation
Step-by-step explanation:
you can just figure this out because when y = 0, that is where the x intercepts are.
so that means that when y = 0, one of the parentheses has to equal to 0 as well, you can only get 0 in this situation when you multiply by 0.
so either x = 0, or some parentheses has to equal to 0.
in the 1 equation when x=0, then y=0, (0,0)
when x = 4, then y = 0, (4,0)
problem solved!
The function has two x-intercepts, one at (0,0) and one at (4,0) is f(x) = x(x - 4). Therefore, option A is the correct answer.
The given coordinate points are (0,0) and (4, 0).
What is a x-intercept?The x-intercept for any curve is the value of the x-coordinate of the point where the graph cuts the x-axis, or we can say that the x-intercept is the value of the x-coordinate of a point where the value of y-coordinate is equal to zero.
A) y=x(x-4)
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept(s): (0,0),(4,0)
y-intercept(s): (0,0)
B) f(x) = x(x + 4)
x-intercept(s): (0,0),(−4,0)
y-intercept(s): (0,0)
C) f(x) = (x - 4)(x-4)
x-intercept(s): (4,0)
y-intercept(s): (0,16)
D) f(x) = (x + 4)(x + 4)
x-intercept(s): (−4,0)
y-intercept(s): (0,16)
The function has two x-intercepts, one at (0,0) and one at (4,0) is f(x) = x(x - 4). Therefore, option A is the correct answer.

What is the value of x in the figure? Enter your answer in the box.
Answer:
x = 65
Step-by-step explanation:
2x + 15 and 145 are vertical angles and congruent, thus
2x + 15 = 145 ( subtract 15 from both sides )
2x = 130 ( divide both sides by 2 )
x = 65
Answer:65
Step-by-step explanation:
2x+15=145. Because opposite angles are equal
2x+15=145
Collect like terms
2x=145-15
2x=130
Divide both sides by 2
2x/2=130/2
x=65

I really need help figuring out what x and y are
Answer:
x = 44, y = 37
Step-by-step explanation:
∠1 and ∠ 4 are adjacent angles and are supplementary, thus
3x + 4 + x = 180
4x + 4 = 180 ( subtract 4 from both sides )
4x = 176 ( divide both sides by 4 )
x = 44
------------
∠ 1 and ∠ 3 are vertical angles and congruent, thus
4y - 12 = 3x + 4 = 3(44) + 4 = 132 + 4 = 136 ( add 12 to both sides )
4y = 148 ( divide both sides by 4 )
y = 37
