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]

A party planner organized a dinner party. The party planner recorded the height of the candlesticks over time and graphed the relationship.
graph with the x axis labeled time in hours and the y axis labeled height of candlestick in inches and a line going from the point 0 comma 9 through the point 3 comma 7
Find and interpret the slope and y-intercept in this real-world situation.
The slope is negative two thirds, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases two thirds of an inch every hour.
The slope is negative three halves, and the y-intercept is 9. The candle starts at a height of 9 inches and decreases three halves of an inch every hour.
The slope is 9, and the y-intercept is negative two thirds. The candle starts at a height of two thirds of an inch and decreases 9 inches every hour.
The slope is 9, and the y-intercept is negative three halves. The candle starts at a height of three halves of an inch and decreases 9 inches every hour.

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 $(1, 4)$.

draw a 55 degree angle
Answers
Answer:
Step-by-step explanation: use a protractor and make a dot in the hole in the center of the line in the protractor. then find 55 on the protractor and draw a straight line from the dot you made to the number 55. if there are no numbers on the protractor, then draw a right angle (90 degrees) and draw a line through it. (45 degrees). Then draw a line through the middle of it, but make it closer to 45 degrees. (You can draw more placement lines if it helps you)
Answer:
Step-by-step explanation:
As 55 is not divisible by 15, we cannot construct 55 degree angle with the help of a compass or a ruler.
So, we need to use the protractor.
Here's how:
Step 1: Draw a random line.
Step 2: Place Protractor on the line as shown.
Step 3: Point the 55 degrees
Step 4: Draw a line towards it.
