Answer:
[tex]\huge\boxed{\sf Area = 32 \ ft.^2}[/tex]
Step-by-step explanation:
Given that, the space is triangular.
So,
[tex]\displaystyle Area \ of \ triangle = \frac{1}{2} (Base)(Height)[/tex]
Here,
Base = b = 10 ft.
Height = h = 6.4 ft.
So,
[tex]\displaystyle Area = \frac{1}{2} (10)(6.4)\\\\Area = (5)(6.4)\\\\Area = 32 \ ft.^2\\\\So, she \ needs \ a \ carpet \ of \ 32 \ ft.^2\ to \ cover \ the \ area.\\\\\rule[225]{225}{2}[/tex]

Explain how to determine whether two quantities are proportional.
Step-by-step explanation: Two quantities have a proportional relationship if they can be expressed in the general form y = kx, where k is the constant of proportionality. In other words, these quantities always maintain the same ratio. That is, when you divide any pair of the two values, you always get the same number k.

Step-by-step explanation:
In February of 2006, there was a
record snowfall of 26.9 inches in one
day in New York City. The normal
snowfall for the month of February in
New York City is 8.5 inches and March
is 5.1 inches. How much more snow
fell in the one day storm in 2006 than
normally falls in February and March
combined
Answer:
40.5 inches
Step-by-step explanation:
I’m not sure if this is correct or not but my thinking is that you just add 26.9, 8.5, and 5.1 together since it says “How much more snow fell in the one day storm in 2006 than normal falls in February and March combined?” And combined basically means all together.
Answer: 13.3 more inches of snow fell in one day storm than normally falls in February and March combined.
February and March combined: 8.5+5.1 = 13.6
Since the question asked how much more, that means you subtract:
26.9 - 13.6 = 13.3
hope this helped =)

What is the vertex of the graph of $y = 3x^2 - 6x + 7$?
Answer:
The vertex of the graph of the equation $y = 3x^2 - 6x + 7$ is the point $(1, 4)$.
Step-by-step explanation:
The vertex of the graph of a parabolic function $y = ax^2 + bx + c$ is given by the formula:
$x = \frac{-b}{2a}$
where a, b, and c are constants and x is the x-coordinate of the vertex.
For the given equation $y = 3x^2 - 6x + 7$, we have a = 3, b = -6, and c = 7. So, we can use the formula to find the x-coordinate of the vertex:
$x = \frac{-b}{2a} = \frac{-(-6)}{2(3)} = \frac{6}{6} = 1$
So, the x-coordinate of the vertex is 1. To find the y-coordinate, we substitute the value of x back into the original equation:
$y = 3(1)^2 - 6(1) + 7 = 3 - 6 + 7 = 4$
So, the vertex of the graph of the equation $y = 3x^2 - 6x + 7$ is the point $(1, 4)$.

Height: 0.25 ft.
How many square feet of contact paper does he need to cover the entire tabletop?
Answer: I do believe that the answer is 7.25 ft squared i hope that im right and this helps you
Step-by-step explanation:
add 3.5+3.5=7
add 7+0.25=7.25ft sqaured
Answer:
Step-by-step explanation:
3.5 as a fraction is 7/2 or 35/10 which equals 3 1/2 3.5 again is 3 1/2 0.25 is 1/4 because 0.25 is in the hundredths place which is 25/100 25 times 4 is 100 so that's why it equals 1/4 so we have to add 3 1/2 + 3 1/2 + 1/4 3+3 is 6 1/2 plus 1/2 is 1 6+1 is 7+ 1/4 is 7 1/4 If you do 25 times 4 its 100 25, 50, 75, 100 1/4 is equal to 25/100 because that's 1 time58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 60° is added to the data, how does the median change?
Answer:
The original data set:
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
Finding the median:
77 and 82 are the 2 middle numbers
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
Do 77 + 82 which equals 159
Then do 159 ÷ 2 which would be 79.5
The median for the original data set would be 79.5
Then adding the 60° would make a new data set:
57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
The middle number would be 77
57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
So the median for the second data set would be 77.
