Answer:

Alicia planted 44% more tulips this year

Step-by-step explanation:

First, we need to divide 65 by 45 to find the ratio of tulips between the years

Then, we take that number, which is 1.4444, and subtract one from it since percents usually aren't over 100%.

So we have 0.444

Multiply by 100 to turn it into a percent

gives you 44.444%

round down

44%

Answer:

44.44444%

Step-by-step explanation:

A percentage calculator explains it easily, so next time you can just search up how to do it. It has helped me a lot with these kinds of problems.

We know that 100%=45 as a percentage.

What we want to find is x%=20, or what percent of 45 is 20?

First, we have to divide 100 by x and 45 by 20.

100/x=45/20

Taking the reciprocal, or flipping both fractions, gives us the answer

x/100=20/45

x=44.44444

Answer:

1.The correct answers here are the options A and C.

Under the United States Constitution, the powers that the states possess are those that are not given to federal government and those that are not prohibited by the Constitution itself. This is clearly seen here in the 10th Amendment. The states are free to set forth any laws that are constitutional so this does not mean any powers people want. 

2.The correct answer here is the option A.

John C. Calhoun believed as did some other prominent politicians that nullification of federal laws was justified as the Constitution does not expressly give Congress the right to control states. But nullification is actually not legal and not true because of the Supremacy Clause that states that the Constitution and the federal laws created in accordance with it are the supreme law of the land. Also,  Article III of the Constitution states that it is the federal judiciary that has the final say in the constitutionality of a law.

3.The correct answer here is the option A.

When the citizens of the United States think about  the Constitution they mainly think about the Constitution of the United States. But before the colonies came together to create the Union they already created their own individual constitutions and entered the Union as free states. But these have been changed after the establishment of the Union in order to more reflect the Constitution of the United States. 

The Fifth Amendment prohibits federal and state governments from carrying out certain actions:

Double Jeopardy: It protects individuals from being tried twice for the same offense after being acquitted or convicted once.

Self-Incrimination: It grants individuals the right not to be compelled to be a witness against themselves in a criminal case.

Due Process: It ensures that no person shall be deprived of life, liberty, or property without due process of law.

Eminent Domain: It establishes that private property cannot be taken for public use without just compensation.

The Fifth Amendment is an essential part of the Bill of Rights and protects various individual rights in the United States legal system.

Answer:

Arithmetic and divergent sequence.

Step-by-step explanation:

We have been given a sequence:

[tex]a_n=4,\frac{10}{3},\frac{8}{3},2...[/tex]

Arithmetic sequence: It is the sequence in which the difference (known as common difference) between consecutive terms is same

Formula for difference: [tex]d=a_n-a_{n-1}[/tex]

Geometric sequence: It is the sequence in which the ratio (known as common ration) between consecutive terms is same.

Formula for ratio: [tex]\frac{a_n}{a_{n-1}}[/tex]

Here, we will first check the common difference

[tex]d=\frac{10}{3}-4=\frac{-2}{3}[/tex]

[tex]\frac{8}{3}-\frac{10}{3}=\frac{-2}{3}[/tex]

[tex]2-\frac{8}{3}=\frac{-2}{3}[/tex]

Hence, we are getting common difference therefore it is an arithmetic sequence.

Answer:

$1062.5

Step-by-step explanation:

Since it is given that Money is increased by 25% from July to December.

Also, Mike deposit $850 in a bank account

Thus, He get money at the end of December = $850 × (100 + 25)%

⇒ Total Money = $850 × 125%

⇒ Total Money = $850 × 1.25

⇒ Total Money = $1062.5

The expression (1/7x + 11/7) can be factored as (x + 11) after dividing each term by 1/7. The factored form simplifies the original expression and represents the common factor, 1/7, that was pulled out.

To factor out 1/7 from the expression (1/7x + 11/7), you can simply divide each term in the expression by 1/7. This is equivalent to multiplying each term by the reciprocal of 1/7, which is 7/1.

Starting with the expression (1/7x + 11/7):

(1/7x) ÷ (1/7) = x

(11/7) ÷ (1/7) = 11

So, factoring out 1/7, the expression becomes x + 11.

Therefore, the factored form of (1/7x + 11/7) is (x + 11).

Answer:

Check attached graph of the line in picture

Step-by-step explanation:

Step-by-step explanation:

We have been given an equation y+6=45(x+3) in point slope form.

It says to use the point and slope from given equation to create the graph.

So compare equation y+6=45(x+3) with point slope formula

y-y1=m(x-x1)

we see that m=45, x1=-3 and y1=-6

Hence first point is at (-3,-6)

slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).

Now we just graph both points (-3,-6) and  (-2,39) and join them by a straight line. Final graph will look like the line in attached graph.

13. The points that shows f(x) = g(x) are (0, 3) and (4, -5)

14a, h(45) = 7 means that after 45 days of planting the height will be 7 cm

14b. h(65) = 11

15a. g(t) = 1

15b. f(x) = 11

16. t = 8

How to find the solution of the graph

13. The solution of the graph is the point of intersection of the line and the curve

14. For the function, the value after the equality sign shows the value h while the value in the parenthesis shows the value for t

15. g(t) = 4t - 7

g(2) = 4(2) - 7 = 1

f(-3) = (-3)² + 2 = 11

f(t) = 14 - 3t

-10 = 14 - 3t

-24 = -3t

-24/-3 = t

t =8

To find the slope of a line, we need to use the formula for finding slope, m, which is:

m = change in y/change in x = y2-y1/x2-x1

This means that we must use the given ordered pairs and substitute these values into the formula above.  However, it is important to remember that x1 and y1 should be from the same pair and x2 and y2 should be from the other pair, otherwise you will get the wrong answer.

Let's let (x1, y1) be (7,3) and (-5,9) be (x2, y2).

Now, we must plug into the formula.

m = (9-3)/(-5-7) = 6/(-12) = -1/2

Therefore, the slope between these two points is -1/2.

Answer:

the first one is -1 15/18 the next one is -1 14/18

Step-by-step explanation:

The mixed numbers that are equivalent to −1 5/6 ​ and​ −1 7/9 are −1 15/18 and −1 14/18, respectively.

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

The LCD is the lowest common denominator for any two or more fractions. Now, for the given mixed numbers the two fractions given are 5/6 and 7/9, therefore, their LCD is the LCM of the denominator, in this case, the denominators are 6 and 9, therefore, the LCM of these two is 18.

Further to get the mixed number, the fraction is needed to be multiplied such that their denominator becomes 18.

Multiply both the numerator and the denominator by 3, therefore,

(5/6) × (3/3) = 15/18

Multiply both the numerator and the denominator by 2, therefore,

(5/6) × (2/2) = 14/18

Thus, the mixed fractions can be written as,

hence, the mixed numbers that are equivalent to −1 5/6 ​ and​ −1 7/9 are −1 15/18 and −1 14/18, respectively.

Final answer:

The y-intercept of function f(x) can be found by using the given points to determine the slope and then plugging in the slope and a point into the point-slope equation. The y-intercept of function g(x) is given by the table. The positive difference in the y-intercept values of f(x) and g(x) is -0.5.

Explanation:

The y-intercept of a linear function represents the value of the function when x is equal to 0. To find the y-intercept of function f(x), we can use the given points (0,1) and (2,7) to determine the slope of the line. The slope is calculated by taking the difference in the y-coordinates and dividing it by the difference in the x-coordinates:

slope = (7 - 1) / (2 - 0) = 3.

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Using the point (0,1) and the slope 3, we get:

y - 1 = 3(x - 0).

Simplifying the equation gives us:

y = 3x + 1.

The y-intercept of function g(x) is given by the table as the value of g(x) when x = -1, which is 1.5.

The positive difference in the y-intercept values of f(x) and g(x) is given by:

1 - 1.5 = -0.5.
