Recipe for cookies calls for 3 1/4 cups of sugar Amy has already put three and one nights cup how many more cups so she need to put in

Answers

Answer:

So she need [tex]\frac{5}{36}\ cups[/tex] more to put in.

Step-by-step explanation:

Given:

Recipe for cookies calls for 3 1/4 cups of sugar.

Amy has already put three and one nine cups.

Now, to find the number of cups she need to put in.

Number of cups of sugar for recipe calls = [tex]3\frac{1}{4} =\frac{13}{4}\ cups.[/tex]

Amy has already put = [tex]3\frac{1}{9} =\frac{28}{9}\ cups.[/tex]

So, to get the number of cups she need to put in we subtract number of cups of sugar for recipe calls from number of cups of sugar for recipe calls:

[tex]\frac{13}{4} -\frac{28}{9}[/tex]

Subtracting by taking the same denominator:

[tex]=\frac{117-112}{36}[/tex]

[tex]=\frac{5}{36}[/tex]

Therefore, so she need [tex]\frac{5}{36}\ cups[/tex] more to put in.

About 106 baby boys are born for every 100 baby girls. Write this as a simplified ratio of males to females

Answers

Answer:

53/50

Step-by-step explanation:

The ratio of males to females is 53:50.

What is Ratio?

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

Number of baby boys = 106

Number of baby girls = 100

So, the ratio of males to females

= 106/100

= 53/50

Hence, the ratio of males to females is 53:50.

A politician’s support grew from 42% by 3 percentage points to 45%. What percent (relative) change is this?

Answers

Answer:

The percent (relative) change is 7.14 percent (%).

Step-by-step explanation:

We are given that the original support value is at 42%.

Then the support increased by 3%, to reach 45%.

We want the Percentage Change (i.e. relative) change of this increase, which can be computed as:

[tex]\frac{X_{F}-X_{O}}{X_{O}}*100[/tex]

where [tex]X_{F}[/tex] is the final value reached

           [tex]X_{O}[/tex] is the original value

So plugging in our known values and computing we have:

[tex]\frac{45-42}{42}*100= \frac{3}{42}*100 = 0.071428*100=7.14[/tex] percent increase.

Now lets go back and check if we are correct.

[tex]42+42\frac{7.14}{100}=42+2.9988=42+3=45[/tex]

(b) Is the 9th term of this sequence larger or smaller than 1/10? Show the calculation that you use to determine your answer.

Answers

The complete question is:

A geometric sequence is defined recursively by

    [tex]a_{(1)}=40\text{ and }a_n=(-1/2)a_{(n-1)}[/tex]

(a) Write out the first four terms of this sequence.

(b) Is the 9th term of this sequence larger or smaller than 1/10? Show the calculation that you use to determine your answer.

Answer:

The 9th term is larger than 1/10.

Explanation:

You are given the first term,    [tex]a_(1)=40[/tex] , and the recursive formula

   [tex]a_{(n)}=(-1/2)a_{(n-1}[/tex]

Thus, you can find the sequence of terms by multiplying each term by the constant ratio, (-1/2).

(a) First four terms of the sequence

[tex]a_{(1)}=40\\ \\ a_{(2)}=40\times (-1/2)=-20\\ \\ a_{(3)}=-20\times (-1/2)=10\\\\ a_{(4)}=10\times (-1/2)=-5[/tex]

Those are the first four terms.

(b) 9th term

You can write the explicit formula of the sequence as:

[tex]a_{(n)}=a_{(1)}\times r^{(n-1)}\\ \\ a_{(n)}=40(-1/2)^{(n-1)}[/tex]

Thus, for the 9th term, n = 9, and the term is:

[tex]a_{(9)}=40\times (-1/2)^{(9-1)}\\ \\ a_{(9)}=40\times(-1/2)^8\\ \\ a_{(9)}=40\times(1/256)=0.1526[/tex]

Since 1/10 = 0.1, and 0.1 < 0.1526, the 9th term is larger than 1/10.

Answers

Final answer:

The graph representing the solution to the system of inequalities y < 2x - 5 and y > -3x + 1 would have a dashed line for the first inequality and a solid line for the second one, with the intersected shading to the left of the lines.

Explanation:

The student's question centers around identifying which graph depicts the solution to the given system of linear inequalities: y < 2x - 5 and y > -3x + 1. The solution to a system of inequalities is represented by the area of intersection between the two shaded regions of the graphs. The first inequality, y < 2x - 5, is a line with a positive slope that passes through (0, -5) and the shading is below the line because 'y' is less than the expression on the right. The second inequality, y > -3x + 1, is a line with a negative slope that passes through (0, 1), and the shading is above the line because 'y' is greater than the expression on the right. Based on these conditions, the correct graph would be the one with a dashed line (indicating 'less than' or 'greater than' but not 'equal to') for the first equation and a solid line (indicating 'less than or equal to' or 'greater than or equal to') for the second equation where the shading on the left side of the lines intersect.

Remember, the slope of a line indicates how steep the line is and is calculated by rise over run. The y-intercept of a line is where the line crosses the y-axis. These key features, along with the type of inequality symbol, determine where and how to shade the graph for a system of linear inequalities.

The y-intercept is [tex]\frac{1}{2}[/tex].

To find the inverse function:

1) Write f(x) = y

2) Switch x and y.

So,

[tex]f(x) = 4x - 2\\y=4x-2\\x=4y-2\\4y=x+2\\y=\frac{\left(x+2\right)}{4}\\y=\frac{1}{4}x+\frac{2}{4}\\y=\frac{1}{4}x+\frac{1}{2}\\f^{-1}\left(x\right)=\frac{1}{4}x+\frac{1}{2}[/tex]

There are 100 students at a swim meet. Every 3rd finisher in the race receives a medal. Every 5th finisher gets a ribbon. How many people will receive a medal AND ribbon.

Answers

Final answer:

Calculating the least common multiple (LCM) of 3 and 5 to determine that 6 students will receive both a medal and a ribbon at a swim meet of 100 students.

Explanation:

To find the number of students at the swim meet who will receive both a medal and a ribbon, we need to look for the common multiples of 3 and 5, as medals are given to every 3rd finisher and ribbons to every 5th finisher. The least common multiple (LCM) of 3 and 5 is 15, which means every 15th student will receive both a medal and a ribbon. Since there are 100 students, we simply divide 100 by 15 and then take the integer part of the result, because we can't have a fraction of a person.

100 ÷ 15 equals approximately 6.66. The integer part is 6, which means 6 students will receive both a medal and a ribbon.
