Draw a line from the top of the 3 m line to the 10 m line so that the new line meets the the 10 meter line at right angles. The part you are interested in should be 4 meters long.
Top rectangle.
Area = L * W
L = 7 (10 - 3 = 7)
W = 4
Area = 4* 7 = 28
Bottom rectangle
Area = L * W
L = 12
W = 3
Area = 12 * 3 36
Total Area 64
You just brought a tank for your fishes. You have a height of 6ft. The length is 5times the width w. The volume of the tank is 600 ft^3. What is the width of the tank to the nearest tenth of a foot? The formula is V = (l)(w)(h)
Answer:
w = 20 feet
Step-by-step explanation:
V = lwh
600 = 5(6)w
600 = 30w
w = 20

(a) Fill in the tavle below to complete the proability distrubution of X
x 1 2 3 4
P(x) 0.3 0.2 ? 0.4
(b) compute the mean of random variable x
Answer:
2.6
Step-by-step explanation:
Given :
x 1 2 3 4
P(x) 0.3 0.2 ? 0.4
Σp(x) = 1
Hence, 0.3 + 0.2 +? + 0.4 = 1
0.9 +? = 1
? = 1 - 0.9
? = 0.1
For the mean :
E(X) = ΣX*P(X)
(1 * 0.3) + (2 * 0.2) + (3 *0.1) + (4* 0.4)
0.3 + 0.4 + 0.3 + 1.6 = 2.6
Hence, the mean = 2.6

10) The Red bus company charges $100 plus
$50 per hour to rent a bus. The Blue bus
company charges $200 plus $25 per hour.
After how many hours do the bus
companies charge the same amount?
Answer:
After 4 hours of renting the bus both companies would charge 300 dollars.
Answer:
4 hours
Step-by-step explanation:
$100 (base price) + 200 (4 hrs at a $50 rate) = $300
$200 (base price) + $100 (4 hours at a $25 rate) = $300

Given a cone with height of 10 cm and a base radius of 9 cm, what is the volume of the cone? Use 3.14 for π. Round your answer to the nearest tenth.
Answer:
848 is the answer
The volume of the cone is approximately 282.74 cubic centimeters.
What is a cone?It is a shape of a Christmas tree where there is a base of radius r and a top point called the apex.
We have,
The formula for the volume of a cone is V = (1/3)πr²h,
where r is the radius of the base and h is the height of the cone.
Substituting the given values.V = (1/3)π(9 cm)²(10 cm)
V = (1/3)π(81 cm²)(10 cm)
V = (1/3)π(810 cm³)
V = (270/3)π cm³
V = 90π cm³
V ≈ 282.74 cm³ (rounded to the nearest tenth)
Therefore,
The volume of the cone is approximately 282.74 cubic centimeters.

Write a quadratic equation in standard form that has the following solutions: x = 4/3 and x = - 2/5
Answer:
15x^2 - 14x - 8 = 0.
Step-by-step explanation:
(x - 4/3)(x + 2/5) = 0
Converted to integer values by multiplying the first bracket by 3 and the second by 5:
(3x - 4)(5x + 2) = 0
Expanding the brackets:
15x^2 + 6x - 20x - 8 = 0
15x^2 - 14x - 8 = 0.

Find the area of the shaded region
Answer:
249.9
Step-by-step explanation:
Area of the shaded region is 223.72 square units.
Step-by-step explanation:
Area of the shaded region = Area of parallelogram - Area of triangle
Area of the parallelogram = base x height
= 23.8 x 15
= 357 square feet
Area of triangle = \frac{1}{2}

x base x height
Let the height of the triangle be represented by h, applying the Pythagoras theorem;
23.8^{2}23.8

= 21^{2}21
2
+ h^{2}h
2
566.44 = 441 + h^{2}h2
h^{2}h
2= 125.44
h = \sqrt{125.44}
125.44
= 11.2
h = 11.2
Area of the triangle = \frac{1}{2}
21 x 23.8 x 11.2 = 133.28
Area of shaded region = 357 - 133.28
= 223.72
Area of the shaded region is 223.72 square units.

Elisa y su sombra forman un ángulo recto . La sombra anide 1,2 m y el ángulo con el que se ve la parte superior de su cabeza desde el extremo de la sombra mide 54° 50° . Calcular la altura de Elisa
Answer:
h = 1.65 m
Step-by-step explanation:
Me parece que el problema está mal formulado por lo siguiente:
El angulo al que se refiere el problema es 54° o es 50° o es 54°,50´
Como resolver el problema en cualquier caso.
Si Elisa y su sombra forman un angulo recto, entonces Elisa, su sombra y la distancia entre la cabeza de Eliza y el final de su sombra forman un triangulo rectangulo. Para el cual entonces solo es necesario buscar la tangente del angulo ( cateto opuesto sobre cateto adyacente) como conocemos el cateto adyacente ( la sombra de Elisa ) calculamos la altura de Elisa (h).
Asumamos que el angulo es de 54° entonces
tang 54° = 1.3763
tang 54° = 1.3763 = h/1.2
h = 1,3763*1,2 m
h = 1.65 m
De igual manera se procedería si el angulo es de 50° ( en este caso la tang 50° = 1.1917
