Answer:
13
Step-by-step explanation:
If we want to find out if there are an equal amount of boys and girls, then we do 22/2 which is 11. BUT, it says there are two more girls than boys. So...
11+2 since there are two more boys than girls. 11+2=13 girls.

Troy made a scale drawing of the Statue of Liberty which has an actual height of 305 feet. He decides to use a scale in which 1 inch represents 25 feet. What is the height in inches of Troy's drawing?
Answer:
Step-by-step explanation:
The height of statue is 12.2 inches in Troy's drawing.
Step-by-step explanation:
Given,
Actual height of statue = 305 feet
Scale used by Troy;
25 feet = 1 inch
1 feet =
305 feet =
305 feet =
305 feet = 12.2 inches
The height of statue is 12.2 inches in Troy's drawing.
Answer:
12.2 inches
Step-by-step explanation:
The scale is 1 inch = 25 ft
305 ft * (1 inch)/(25 ft) = 305/25 inches = 12.2 inches
Answer: 12.2 inches

Michael and Landon work at a dry cleaners ironing shirts. Michael can iron 40 shirts per hour, and Landon can iron 20 shirts per hour. Michael and Landon worked a combined 14 hours and ironed 360 shirts. Graphically solve a system of equations in order to determine the number of hours Michael worked, ,x, and the number hours Landon worked, y.
I need two equations in y=mx+b form pls
Answer:
Michael worked 4 hours and Landon worked 10 hours.
Step-by-step explanation:
Michael can iron 40 shirts each hour, so in xx hours he can iron 40x40x shirts. Landon can iron 20 shirts each hour, so in yy hours he can iron 20y20y shirts. The total number of shirts ironed 40x+20y equals 360:
40x+20y=360
40x+20y=360
Since Michael and Landon worked a combined 14 hours, we know x+yx+y must equal 14.
x+y=14
Write System of Equations:
40x+20y= 360
x+y=14
Solve for y in each equation:
40x+20y = 360 x+y = 14 20y = -40x+360
[tex]\frac{-20y}{20}[/tex] =[tex]\frac{-40x+360}{20}[/tex]
y = -2x+18
At what value of x does the second
function's output exceed (get bigger
than) the first function's output?
Explain your solution steps.
f(x)= x+7 and f(x)= x²)
The second function's output exceeds (get bigger than) the first function's output for x∈(-∞,[tex]\frac{1-\sqrt{29} }{2}[/tex])∪([tex]\frac{1+\sqrt{29} }{2}[/tex],∞)
Given the functions f(x)=x+7 and f(x)=[tex]x^{2}[/tex]
To know when to exceed, need to equate both functions.
⇒[tex]x^{2} =x+7[/tex]
⇒[tex]x^{2} -x-7=0[/tex]
x=[tex]\frac{-b+\sqrt{D} }{2a}[/tex] and [tex]\frac{-b-\sqrt{D} }{2a}[/tex]
⇒x=[tex]\frac{1-\sqrt{29} }{2}[/tex],[tex]\frac{1+\sqrt{29} }{2}[/tex]
f(x)=[tex]x^{2}[/tex] decreases from -∞ to 0 and increases from 0 to ∞ it cuts the graph of x+7 two times and for x∈(-∞,[tex]\frac{1-\sqrt{29} }{2}[/tex])∪([tex]\frac{1+\sqrt{29} }{2}[/tex],∞) f(x)=[tex]x^{2}[/tex] is greater than f(x)=x+7
Therefore,The second function's output exceeds (get bigger than) the first function's output for x∈(-∞,[tex]\frac{1-\sqrt{29} }{2}[/tex])∪([tex]\frac{1+\sqrt{29} }{2}[/tex],∞)

Two health clubs offer different pricing plans for their members. Both health clubs charge a one-time sign-up fee and a monthly membership fee. The graph below represents what Health Club A charges.
The table below represents what Health Club B charges.
Answer:
The answer is below
Step-by-step explanation:
The question is not complete but I would show how this charges can be represented by an equation.
For health club A:
The graph (x, y) passes through the points (2, $136) and (4, $242). Let x represent the total months and y represent the total charges. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-136=\frac{242-136}{4-2}(x-2)\\\\y-136=53(x-2)\\\\y-136=53x-106\\\\y=53x+30[/tex]
For health club B:
The table (x, y) has the points (4, 173) and (6, 23y). Let x represent the total months and y represent the total costs. The equation is given by:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)\\\\y-173=\frac{237-173}{6-4}(x-4)\\\\y-173=32(x-4)\\\\y-173=32x-128\\\\y=32x+45[/tex]
What is your monthly take-home pay if your take-home pay is $1034.65 every two weeks? Round intermediate calculations and the final answer to the nearest cent; use 365 days in a year.
The monthly take-home pay is $2240.83.
What is Algebraic expression ?
Algebraic expression can be defined as combination of variables and constants.
To calculate the monthly take-home pay, we need to first find the annual take-home pay and then divide by 12 (since there are 12 months in a year).
We are given that the take-home pay is $1034.65 every two weeks, which means the total take-home pay for a year can be calculated as follows:
annual take-home pay = 1034.65 * 26 = 26889.9
Next, we divide the annual take-home pay by 12 to get the monthly take-home pay:
monthly take-home pay = 26889.9 / 12 = 2240.825
Rounding this to the nearest cent, we get:
monthly take-home pay = $2240.83
Therefore, the monthly take-home pay is $2240.83.

Yes; the domain values are at regular intervals and the range values have a common factor of 0.25 so option (D) will be correct.
What is the range and domain of a function?A function's range is the set of all values that the function accepts, and its domain is the set of all values for which the function is defined.
The domain is for the independent variable while the range is for the dependent variable.
Given a table of dependent(x) and independent variable (y)
Now the domain is set of the dependent variable so x {3,2,1,-1} so it is decreasing between two points so it is an interval.
Now in the independent variable (x)
If we multiply by 0.25 then the next term will come so it has a common factor of 0.25.
Hence "Yes; the domain values are at regular intervals and the range values have a common factor of 0.25".

the density of a certain material is such that it weighs 9 kilograms for every 7 cubic feet of volume. express this density in pounds per pint.
The density in pounds per pint is 0.047 pounds per pint
Density is calculated using the formula -
Density = [tex]\frac{mass}{volume}[/tex]
To find the density in pounds per pint, we will convert mass and volume to the respective units.
Converting mass in kilograms to pounds -
1 kilogram = 2.205 pounds
9 kilograms = [tex]\frac{2.205*9}{1}[/tex]
9 kilograms = 19.84 ppounds
Converting volume in cubic feet to pints -
1 cubic foot = 59.844 pints
7 cubic foot = [tex]\frac{59.884*7}{1}[/tex]
7 cubic foot = 418.9 pints
Now, keeping the values in formula to find density
Density = [tex]\frac{19.84}{418.9}[/tex]
Performing division to find density -
Density = 0.047 pounds per pint
Hence, the density in pounds per pint is 0.047.

What is Quart measurement ?The quart is a measurement which is use to find the capacity of liquid. Or we can say Quart is a unit of liquid volume which is measured in gallon. There are different measurements into which we can convert the unit such as ounces and liters.
Mathematically, we can write :
1 quart = 32 fluid ounces
or
1 quart = 0.94 US liters = 4 cups (approx.)
According to question,
[tex]1\frac{1}{2}[/tex] quarts of water = 3/2 quarts of water = 3/4 quarts of grape
let, 15 /4 quarts of sparkling water = x

We draw the parabola with the vertex at (0,4) Basically plot point (0,4) then draw parabola.

So the shade will be outside of the curve and not inside.

Stephanie's school is selling tickets to a play. On the first day of ticket sales the school sold 4 adult tickets and 10 student tickets for a total of $150. The school took in $105 on the second day by selling 1 adult ticket and 10 student tickets. What is the price each of one adult ticket and one student ticket?
Answer:
The price of
1 adult ticket = $15
1 student ticket = $9
Step-by-step explanation:
Let
The price of adult tickets be represented by a
The price of student tickets be represented by s
Therefore:
On the first day of ticket sales the school sold 4 adult tickets and 10 student tickets for a total of $150.
4a + 10s = $150.... Equation 1
The school took in $105 on the second day by selling 1 adult ticket and 10 student tickets.
a + 10s = $105.... Equation 2
a = $105 - 10s
Therefore, we substitute : $105 - 10s = a in Equation 1
4a + 10s = $150.... Equation 1
4($105 - 10s) + 10s = $150
$420 - 40s + 10s = $150
Collect like terms
- 40s + 10s = $150 - $420
-30s = -$270
Divide both sides by -30
-30s/-30 = -$270/-30
s = $9
We find a
a = $105 - 10s
a = $105 - 10($9)
a = $105 - $90
a = $15
Therefore, the price of
1 adult ticket = $15
1 student ticket = $9
