Answer:
[tex]900\times 3^m[/tex] = 100
Step-by-step explanation:
The number of visitors is modeled by the expression [tex]900\times 3^m[/tex]
Where m is the number of months after the number of visitors was measured.
We need to evaluate the above expression for m = -2.
So,
[tex]900\times 3^m=900\times 3^{-2}\\\\=900\times \dfrac{1}{3^2}\\\\=900\times \dfrac{1}{9}\\\\=100[/tex]
At m = -2, the value of the above expression is equal to 100.

Answer:
Area =0.41 units^2
Step-by-step explanation:
sin 26 degrees=height/1.53

Data given:
14, 6, 2x, 8, 10, 4The mean is
mean = sum of the data / number of data(14 + 6 + 2x + 8 + 10 + 4)/6 = 842 + 2x = 6*82x = 48 - 422x = 6x = 35. Let the added number is x, then the mean is:
(2 + 8 + 7 + 4 + 9 + x)/ 6 = 6x + 30 = 36x = 36 - 30x = 6Solve the following system of equations

If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Answer:
$36.38
Step-by-step explanation:
If the sales tax rate is 7% in New York, then how much sales tax would you pay in New York for a $34 pair of pants?
Given data
Tax= 7%
Cost = $34
Let us solve for the amount of tax
=7/100*34
=0.07*34
=2.38
Hence the total is =2.38+34
=$36.38
What is the value of 3(x - y) if x = 9 and y = -2*

A 2-column table with 9 rows. The first column is labeled year with entries 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. The second column is labeled pounds of trash with entries 3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44.
The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use the statistics calculator to calculate the mean and median. Round the answers to the nearest hundredth.
Answer:
The median of a list of numbers is the center number when you order the numbers from least to greatest.
Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.
Step-by-step explanation:
List in order from least to greatest
(3.25, 3.25, 3.66, 3.83) 4.44 ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher. So the median number is 4.44
For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74) = 36.85 Then divide by 9 = 4.09

Micheal plays 1/15 of a song in 1/5 of a minute. How many minutes will it take to play the whole song?
Answer:
3 minutes
Step-by-step explanation:
To find how many minutes it will take to play the whole song, multiply 1/5 by 15
15(1/5)
= 3
So, it will take 3 minutes to play the whole song
Answer:
Given :-Micheal plays 1/5 part of song in 15 minTo Find :-Time taken to complete whole song
Solution :-Let the time taken be x

I'm confused on this
Answer:
y= -2/3x +4
Step-by-step explanation:
(0,4) and (6,0)
m= (y2-y1)/(x2-x1)
m= (0-4)/(6-0)
m= -2/3
y-y1=m(x-x1)
y-4= -2/3(x-0)
y-4= -2/3x
y= -2/3x +4
Answer:
D
Step-by-step explanation:
Almost positive it's D. When you take two points on the line, you'll get a slope of 2/3. Since it's going down left to right, it's going to be negative. SOOO -2/3. The y-intercept is 4 because, well that's where the line crosses the y-axis.

Answer:
204
Step-by-step explanation:
The area of the top triangle = 5*12/2 = 30
The area of the bottom triangle = 30
The hypotenuse of the top triangle is
5^2 + 12^2 = hypotenuse^2
25 + 144 = hypotenuse^2
169 = hypotenuse squared.
hypotenuse = sqrt(169)
hypotenuse = 13
Now the back face = 13 * 8 = 104
The area of the left side rectangular face = 5*8 = 40
The total area = 30 + 30 + 104 + 40 = 204

A scale drawing of a house shows 9cm x10cm. If
6cm=12 ft, what are the actual dimensions?
Answer:
18ft x 20ft
Step-by-step explanation:
(I'm kinda in a rush so I can't explain right now, sorry!)
Hope that helped though :)
The actual dimensions of the house is 18 feet by 20 feet.
Scaling is used to either increase or decrease the size of a figure to create an image.
Given that a scale of 6cm to represent 12 ft. Hence:
9 cm = 9 cm * (12 ft. per 6 cm) = 18 feet.
10 cm = 10 cm * (12 ft. per 6 cm) = 20 feet.
The actual dimensions of the house is 18 feet by 20 feet.

Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same recipe. He will make h pans of pumpkin bars using g cups of sugar. Which of these equations best represents the relationship between h and g?
Answer:
[tex]2.5h = 3g[/tex]
Step-by-step explanation:
Given
[tex]Sugar = 2\frac{1}{2}\ cups[/tex]
[tex]Bars = 3\ pans[/tex]
Required
Determine the equation for h pans and g cups
We have that:
[tex]Sugar = g[/tex]
[tex]Bars = h[/tex]
To do this, we make use of the following equivalent ratios.
[tex]Bars : Sugar = Bars : Sugar[/tex]
So, we have:
[tex]3 : 2\frac{1}{2} = h : g[/tex]
Express fraction as decimal
[tex]3 : 2.5 = h : g[/tex]
Express as fraction
[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]
Cross multiply
[tex]2.5h = 3g[/tex]
