Alicia needs to purchase carpet to cover a triangular space.
The space has a base length of 10 ft. and a height of 6.4 ft.
How many square feet of carpet does Alicia need to cover the space?
Answers
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]

What is the vertex of the graph of $y = 3x^2 - 6x + 7$?
Answers
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 $(1, 4)$.

The diagonal of a television measures 27 inches. If the width is 22 inches, calculate its height to the nearest inch.
Answers
Answer:
16 inches
Step-by-step explanation:
We can use the Pythagorean theorem to find the height of the television. The Pythagorean theorem states that in a right triangle, the sum of the squares of the lengths of the two smaller sides is equal to the square of the length of the longest side (the hypotenuse). In this case, the diagonal of the television is the hypotenuse and the width and height are the other two sides.
So, we can set up the equation as follows:
a^2 + b^2 = c^2
where a is the width (22 inches), b is the height, and c is the diagonal (27 inches).
We can solve for b:
b^2 = c^2 - a^2
b^2 = 27^2 - 22^2
b^2 = 729 - 484
b^2 = 245
b = √245
b = 15.56 inches (rounded to two decimal places)
So, the height of the television to the nearest inch is 16 inches.

If a value of 60° is added to the data, how does the median change?
Answers
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.
Step-by-step explanation:
Hope this helps you a little, you're welcome
57, 58, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105
77 and 82 are both the middle numbers
Step 2: add the two middle numbers
77 + 82 = 159
Step 3: divide your sum by 2.
159 divided by 2 equals to 79.5
The median for the original data set would be 79.5.
For the new data set, you add 60 to the data set.
Step 1: find the new data set
57, 58, 60, 61, 66, 71, 77, 82, 91, 95, 100, 102, 105.
Step 2: find the middle number.
The middle number is 77.
The median for the new data set is 77.

C. (1, 4)
D. (-1, -1)
(Would like a explaination btw!)
Answers
Answer:
1,0 B
Step-by-step explanation:
Explanation: So you have to solve the equation, so it would go like this
y = 2x - 2
y = 2 x 1 -2
y = 0
And x is equal to 1
x is equal to one because we substitute the x in the equation starting from 1 or -1 however you want to go and substitute the x to get what 6. So like you see how I solved the equation using 1 as x you get (1, 0)

Answer:

Step-by-step explanation:
You add the 11x and 58
Answer: hope this helps ♡ (i wont mind getting brainliest )
x = 3
Step-by-step explanation:
z° and 89° are two opposite angles.
z° = 89°
89° + 89° + (11x + 58)° + (11x + 58)° = 360° (adds up to 360° coz its a circle)
178° + (11x + 58)° + (11x + 58)° = 360°
178° + 58° + 58° + (11x + 11x)° = 360°
178° + 116° + 22x° = 360°
294° + 22x° = 360°
294° - 294° + 22x° = 360° - 294°
22x = 66
22x ÷ 22 = 66 ÷ 22
x = 3
(double check: 11×3 = 33 2×(33+58)+178=360° ✓)
At the school festival,Heather can buy 25 game tickets for $10,or she can. Pay $ 0.50 Per game ticket. Which option has the lesser price per ticket
Answers
Answer:25 game tickets for $10
Step-by-step explanation:
0.50 * 25 = $12.5
so the second option is more expensive so the first one is correct.
Divid $10 by 25 and it breakdown to 0.40 cents
That is a better deal than 0.50 per game.
25 for $10 is the better deal

Answers
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 =)
