it should be 31.5 kids get balloon animals

Answer:

Balloon Animals: 10 children

Face Paint: 35 children

Step-by-step explanation:

To find out how many children get balloon animals, divide 105 by 10. Your answer will be 10.5, but ten and a half children can't get balloon animals (it's physically impossible) so we would have to round down to 10. To find out how many children get their faces painted, you would divide 105 by 3, which would give you 35. So 35 children would get their faces painted.

Answer: b. borrow $840 for 1 week at an APR 550%, since jimmie will owe less interest this way than with the fee of $90. APEX

The "better" deal is borrowing borrow $840 for 1 week at an APR of 550%

What is APR 550% mean?

The interest on the borrowing amount for one year on the credit card.

Jimmie has a borrowing APR is 550%

One month interest 5.50÷12

                                   ⇒0.4583

For one day =0.4583/30

                      =0.01527

for one week=0.01527*7

Answer:

8(3 + 8)

Step-by-step explanation:

Note that 8 is a factor common to both 24 and 64.

Thus, 8(3 + 8) is equivalent to 24 + 64.

Answer is number a

First you find the common factor between 24 and 64 and you factor it out and divide both numbers by it

8(3+8)

To find how many gallons of seawater contain 2.5 pounds of salt, convert the salt to ounces (40 ounces) and divide by the salinity concentration (1.2 ounces per liter) to get 33.33 liters. Then convert liters to gallons, resulting in approximately 8.8 gallons of seawater.

To solve this problem, we need to convert all units to be compatible and calculate the amount of seawater needed to obtain 2.5 pounds of salt based on the salinity given.

First, we convert 2.5 pounds of salt to ounces because the salinity is given as 1.2 ounces per liter. Since 1 pound is equal to 16 ounces, we have 2.5 pounds * 16 ounces/pound = 40 ounces of salt.

Next, we divide the total ounces of salt by the salinity concentration to find out how many liters of seawater we need:

40 ounces of salt / 1.2 ounces of salt per liter = 33.33 liters of seawater.

Then, we convert liters of seawater to gallons. There are approximately 3.785 liters in a gallon, so:

33.33 liters / 3.785 liters per gallon = 8.8 gallons

Therefore, to the nearest tenth of a gallon, it would take 8.8 gallons of seawater to contain 2.5 pounds of salt.

Final answer:

To compare two-way frequencies in a relative frequency table, calculate the relative frequency by dividing each frequency by the total number of data values, and find the cumulative relative frequency by summing up the previous relative frequencies.

Explanation:

To compare two-way frequencies in a relative frequency table, you start by calculating the relative frequency. This is done by dividing the frequency by the total number of data values for that group. For cumulative relative frequency, add the relative frequencies of all preceding rows to the relative frequency of the current row. Let's clarify using an example.

In the first row, if the relative frequency is .15, this is the cumulative frequency as well since it's the first value. For the second row, if the relative frequency is .25, we add this to the .15 from the first row to get a cumulative relative frequency of .40. Continue this process down each row.

When constructing a histogram using these frequencies, scale the x-axis in increments suitable to the data range (e.g., $50 widths) and plot relative frequencies on the y-axis. The sum of the relative frequency column should total 1 (or 100% if in percentage form), as it represents the entire sample.

The difference between relative frequency and frequency is that frequency is the absolute count of occurrences, while relative frequency expresses this count as a proportion of the total number of data values. Cumulative relative frequency is the sum of all previous relative frequencies, showing the accumulation of data up to that point.

First find the x and y values because where the lines will intersect, they share the point of the intersection so they will share the x and y coordinates.

Rearrange equations

[tex]4x + y = 19[/tex]

[tex] - 2x + y = 1[/tex]

To cancel y, we must do equation 1 minus equation 2. Similarly:

[tex]4x - - 2x = 4x + 2x = 6x[/tex]

[tex]19 - 1 = 18[/tex]

[tex]6x = 18[/tex]

[tex]x = 18 \div 6 = 3[/tex]

So the x coordinate is 3.

The y coordinate can be found with substitution of x into one of the equations:

[tex]y = 2x + 1 = 2(3) + 1 = 7[/tex]

So where the two lines intersect is at the point (3, 7), which is the solution to the equations.

Answer:

The correct option is 2.

Step-by-step explanation:

The given system of equations is

[tex]y=-4x+19[/tex]           ..... (1)

[tex]y=2x+1[/tex]               ..... (2)

The slope intercept form of a line is

[tex]y=mx+b[/tex]             .... (3)

where, m is slope and b is y-intercept.

From (1) and (3), we get

[tex]m=-4,b=19[/tex]

The slope of first line is -4 and the y-intercept is 19. It means it is a decreasing line and intersect the y-axis at (0,19).

From (2) and (3), we get

[tex]m=2,b=1[/tex]

The slope of first line is 2 and the y-intercept is 1. It means it is an increasing line and intersect the y-axis at (0,1).

Put y=0, to find the x-intercepts.

[tex]0=-4x+19\Rightarrow x=\frac{19}{4}=4.75[/tex]

[tex]0=2x+1\Rightarrow x=\frac{-1}{2}=-0.5[/tex]

Therefore the x-intercept of first line is 4.75 and the x-intercept of the second line is -0.5.

Only the second graph satisfy all the above condition.

One solving the given equation we get

[tex]-4x+19=2x+1[/tex]

[tex]19-1=2x+4x[/tex]

[tex]18=6x[/tex]

Divide both sides by 6.

[tex]3=x[/tex]

Put this value in equation (1).

[tex]y=-4(3)+19=-12+19=7[/tex]

Therefore the solution of the given system of equation is (3,7).

Hence the correct option is 2.

awnser: 42

step by step:

1. find the racio of both

2.multiply the awnsers by 7

3.finally subtract

The answer is 42 because to find how meant men and women started at on the the first day you do

177/3=59 and 159/3=53

Then you times those numbers separately by 7. So 59*7=413 and 53*7=371

Then you do 413 men-371 women=42 more men then women.

Answer:

The perimeter of a shape is the sum of the measurements of all sides. Since a rectangle have equal lengths and widths, you can just add the numbers twice.

So, 15 + 15 + 8 + 8. So the perimeter is 46 cm.

Answer:

E. 46

Step-by-step explanation:

The perimeter of a square or rectangle can be found by using the following formula:

(length + legnth) + (width + width) = perimeter

Our length here is 15 and the width is 8, so substitute the values into the equation.

(15 + 15) + (8 + 8) = perimeter

Now solve

(15 + 15) + (8 + 8)

(30) + (8 + 8)

(30) + (16)

=46

Therefore, the perimeter (and answer) is E. 46

Answer:

The median, because the data distribution is skewed to the right

Step-by-step explanation:

Min= 10.5

Q1 = 11.5

Median = 12.5

Q3= 13.5

Maximum = 15

The data is skewed towards the right because more values towards the right side as compared to the left side.

For data to be symmetrical, it has same shape on both sides of the median, which in our case is not possible.

So, for skewed data we always prefer median because it is less affected by the outliers and if mean is chosen, the value of mean is biased towards the side that has larger values while median does not get affected by it. So, we choose median.

our correct option will be:

The median, because the data distribution is skewed to the right

Answer:

the correct answer is the third one.  (1, 16), (2, 20), (3, 24)

Step-by-step explanation:

A perimeter is a path that surrounds a two-dimensional shape.

In the first case, 1 rectangle, the perimeter is the sum of all the sides:

Perimeter = 6 + 2 + 6 + 2 = 16

In the second case, 2 rectangles, the perimeter is the sum of all external sides:

Perimeter = 6 + 2 + 2 + 6 + 2 + 2 = 20

In the third case, three rectangles, the perimeter is the sum of all external sides:

Perimeter = 6 + 2 + 2 + 2 + 6 + 2 + 2 + 2 = 24

In none of the cases, you take into consideration the interal sides. Just the external sides, so the correct answer is the third one.

Answer:

x = 8

Step-by-step explanation:

The two angles are complementary angles, which means they add to 90 degrees

6x + (4x+10) = 90

Combine like terms

10x+10 = 90

Subtract 10 from each side

10x+10-10=90-10

10x = 80

Divide each side by 10

10x/10=80/10

x = 8

Answer:

Step-by-step explanation:

Step-by-step explanation:

Well you got a good start.  #16 = 105°, #17 = 27°, and #15 = 48°.

Inscribed angles are half the arc angle, so #3 = #10 = 21°, and #4 = #5 = 39°.

That means #14 = #12 = 120°, and #11 = #13 = 60°.

The sum of the angle arcs is 360°, and AD is the diameter, so it splits it in half.  So arc BC is 180 - 78 - 42 = 60°, so #1 = 30°.

Therefore, #2 = 90°.

AG and FG are both radii, so AGF is an isosceles triangle.  Therefore, #8 = #9 = 66°.

Similarly, FG and DG are both radii, so FGD is an isosceles triangle.  So #6 = #7 = 24°.

That means #18 = 129°.  So #20 = 129° and #19 = #21 = 51°.

That's all of them.

Step-by-step explanation:

The domain of the function is defined as the possible x values that can be used in this function. Now, taking a look at the given graph, we would find that the line starts from x = 0 and continues taking x values till it reaches x = 0This means that for this function, we are allowed to use x values that are greater than or equal to zero and less than or equal to 8Therefore, the domain is any x value greater than or equal to zero and less than or equal to 8

The correct answer to the question is option (2): [tex]\( h\left(\frac{x}{3}\right) \).[/tex]

To address the question about the horizontal stretching of the graph of a function [tex]\( f(x) \)[/tex] by a factor of 3, we need to understand how transformations affect the graph of a function. Here are the steps to determine the correct transformation:

1. Identify the Base Function: Recognize that the graph in question is of some function [tex]\( f(x) \)[/tex]. We don't need to know the form of \( f(x) \) to understand how it will be transformed.

2. Understand Horizontal Stretching: A horizontal stretch by a factor of [tex]\( a \)[/tex] is achieved by replacing every [tex]\( x \)[/tex] in the function with [tex]\( \frac{x}{a} \)[/tex]. In this case, [tex]\( a = 3 \).[/tex]

3. Apply the Stretch to the Function: Replace [tex]\( x \)[/tex] with [tex]\( \frac{x}{3} \)[/tex]in the function [tex]\( f(x) \).[/tex]

4. **Write Down the Transformed Function**: The new function after the horizontal stretch will be [tex]\( f\left(\frac{x}{3}\right) \).[/tex]

5. **Choose the Correct Answer**: Look for the choice that represents the transformation [tex]\( f\left(\frac{x}{3}\right) \).[/tex]

The correct transformation that indicates a horizontal stretch by a factor of 3 is:

[tex]\[ f\left(\frac{x}{3}\right) \][/tex]

This means that for any given value of [tex]\( x \)[/tex] in the original function, its corresponding point on the graph will now be three times further away from the y-axis, thus stretching the graph horizontally. If the original function had a point at [tex]\( (x, y) \)[/tex], the new function after the stretch will have a corresponding point at [tex]\( (3x, y) \)[/tex], which means the x-values have been stretched out.

Now, from the options given in the image:

1. [tex]\( h(3x) \)[/tex] represents a horizontal compression by a factor of 3, not a stretch.

2. [tex]\( h\left(\frac{x}{3}\right) \)[/tex] is the correct representation of a horizontal stretch by a factor of 3.

3. [tex]\( h(x) + 3 \)[/tex] represents a vertical shift upwards by 3 units.

4. [tex]\( 3h(x) \)[/tex] represents a vertical stretch by a factor of 3.

Therefore, the correct answer to the question is option (2): [tex]\( h\left(\frac{x}{3}\right) \).[/tex]

Answer:

109.38

Step-by-step explanation:

Recall the formula for compound interest is as follows:

         A  =  P·(1  +  r/n)nt ,   where

    P = principal amount (initial amount deposited)

     r = annual rate of interest (in decimal form)

     t = # of years amount is deposited for

    n = # of times interest is compounded per year

    A = amount accumulated after t years, including interest

The problem asks how much money Heather will have in the bank by her 16th birthday when she deposited $100 on her 13th birthday in a bank with 3% interest compounded quarterly. From this, we have the following information:

    P = $100

    r = 0.03     ==>     3%/100% = 0.03

    t = 3 years     ==>     16 - 13 = 3

    n = 4     ==>     since there are 12 months per year and 12/4 = 3 months,

                then interest is compounded  every 3 months which is a total of 4 times per year

Therefore,

         A = P(1 + r/n)nt

            = 100(1 + 0.03/4)4·3

            = 100(1 + 0.0075)12

            = 100(1.0075)12

            = 109.38069

            ≈ 109.38

Thus, Heather will have $109.38 in the bank by her 16th birthda
