Answer:
Slope = -1Step-by-step explanation:
co-ordinates = (4,7) and (1,10)
Slope = (y² -y¹) / (x² - x¹)
= (10-7) / (1-4)
= 3 / -3
= -1

What is the area of the composite figure?
Answer:
59.5
Step-by-step explanation:
Fig = square + triangle
Area of square = s x s = 7^2 = 49 sq.cm
Area of triangle = 1/2 bh = 1/2 x 3 x 7 = 10.5 sq.cm
Area of fig = area of sq + area of triangle = 49 + 10.5 = 59.5 cm^2
I hope im right!!

The data shows the speed, in miles per hour, of motorists on a stretch of
road.
42, 35, 44, 31, 47, 41, 36, 34, 39, 18, 37, 32, 37, 33, 43, 41, 44, 47, 46
18 miles per hour is an outlier.
0 47 miles per hour is an outlier.
The outlier decreases the mean speed.
The outlier decreases the median speed.
Answer:
18 miles per hour is an outlier
the outlier decreases the mean speed
Step-by-step explanation:
the low number of 18 is way different from the other numbers being in the 30's and 40's
this 18 will bring the mean of all the numbers own because it is a smaller number.
Answer:
Step-by-step explanation:
Mean:44
Median:31

In a high school orchestra, the ratio of cellos to violins is 1 to 3. There are 21 violins. Write and solve a proportion that gives the number c of cellos in the orchestra.
Answer:Number of cellos =7
Step-by-step explanation:
The ratio of cellos to violins is 1 to 3=1:3
Total ratio = 1+3=4
To find the total number of cellos and violins in the orchestrs,
Ratio of violins/ Total ratio x Total number of cellos and violins = Number of violins
3/4 x X= 21
X=21 x 4 / 3
X =7x 4 28.
Number of cellos =Ratio of cellos / Total ratio x Total number of cellos and violins
=1/4 x28
=7 cellos

Martha sells custom painted square canvases. She determined that the amount of tissue paper she'll need to wrap each canvas can be represented by
y= x^2 + 2x + 1, where y is the total square inches of tissue paper and x is the side length of the canvas in inches. Write and solve an equation to determine the side length of the canvas is Martha needs 49 square inches of tissue paper.
Given:
The equation is
[tex]y=x^2+2x+1[/tex]
where y is the total square inches of tissue paper and x is the side length of the canvas in inches.
To find:
The side length of the canvas is Martha needs 49 square inches of tissue paper.
Solution:
We have,
[tex]y=x^2+2x+1[/tex]
Putting y=49, we get
[tex]49=x^2+2x+1[/tex]
[tex]0=x^2+2x+1-49[/tex]
[tex]0=x^2+2x-48[/tex]
Splitting the middle term, we get
[tex]0=x^2+8x-6x-48[/tex]
[tex]0=x(x+8)-6(x+8)[/tex]
[tex]0=(x+8)(x-6)[/tex]
Using zero product property, we get
[tex]x+8=0[/tex] and [tex]x-6=0[/tex]
[tex]x=-8[/tex] and [tex]x=6[/tex]
Side length cannot be negative. So, only possible value of x is 6.
Therefore, Martha needs 6 inches side length of the canvas for 49 square inches of tissue paper.

La profundidad de una alberca aumenta paulatinamente desde 0.80 metros hasta 3 metros en una longitud de 10 metros cual es el angulo de inclinacion de la alberca
Answer:
El ángulo de inclinación de la alberca es aproximadamente 12.407º.
Step-by-step explanation:
Puesto que conocemos la distancia horizontal ([tex]l[/tex]) y la variación en la profundidad ([tex]h[/tex]) de la alberca, en metros, podemos emplear la siguiente razón trigonométrica para calcular el ángulo de inclinación de la alberca ([tex]\alpha[/tex]), en grados sexagesimales:
[tex]\alpha = \tan^{-1}\left(\frac{h}{l} \right)[/tex] (1)
Si sabemos que [tex]l = 10\,m[/tex] y [tex]h = 2.20\,m[/tex], entonces el ángulo de inclinación de la alberca es:
[tex]\alpha \approx 12.407^{\circ}[/tex]
El ángulo de inclinación de la alberca es aproximadamente 12.407º.

The diameter of a circle is 38 miles. What is the circle’s area?
Use 3.14 for pi
Area of circle formula: πr^2
Since the radius is half of the diameter, divide 38 by two.
r = 19 miles
A = π(19)^2 = π(361)
Now, substitute in 3.14 for π
A = 3.14(361) = 1133.54
