Answer:
The interior angles of a triangle add to 180°:a + b + c = 180°
Angles c and d make a straight angle, which is 180°:d + c = 180°
So d + c equals a + b + c:d + c = a + b + c.
Subtract c from both sides:d = a + b.

A dolphin is swimming at a depth of –3.4 meters with respect to sea level when it begins diving deeper at a constant rate of –0.25 meter per second. In how many seconds will the dolphin reach a depth of 9.9 meters below sea level?
Answer: 26 s
Step-by-step explanation:
Given
Dolphin is 3.4 meters below the sea level
It started moving at a rate of [tex]-0.25\ m/s[/tex]
Distance travel in the vertical direction by dolphin is
[tex]\Rightarrow 9.9-3.4=6.5\ m[/tex]
time taken is given by
[tex]\Rightarrow time(t)=\frac{\text{Distance}}{\text{Speed}}\\\\\Rightarrow t=\frac{6.5}{0.25}=26\ s[/tex]

Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970 y en 2001 se incrementó 2,25 veces en relación a 1988. ¿Cuántos habitantes había en el año 2001?
Answer:
En 2001 el pueblo poseía 45.826 habitantes.
Step-by-step explanation:
Un pueblo tenía 13.578 habitantes en 1970. En 1988 la población se incrementó 1,5 veces con respecto a 1970. Para calcular entonces la población en 1988 debes realizar el siguiente cálculo:
13.578*1,5= 20.367
Por lo que en 1988 el pueblo poseía 20.367 habitantes.
En 2001 se incrementó la población 2,25 veces en relación a 1988. Para calcular entonces la población en 2001 debes realizar el siguiente cálculo:
20.367* 2,25= 45.825,75≅ 45.826
Por lo que en 2001 el pueblo poseía 45.826 habitantes.
Find the total surface area of this cone.
Leave your answer in terms of .
4ft
3ft
SA = [?] ft2
Enter
Total surface area is: 21 ft²
Lateral area is: 12π ft²
The total surface area of this cone is 21π square feet.
What is the total surface area of the cone?The total surface area of the cone is given by the following formula;
[tex]\rm Surface \ area=\pi r(r+l)[/tex]
Where h denotes the height of the cone and r is the radius and l is the slant height.
The radius of the cone = 3
The height of the cone = 4
Substitute all the values in the formula
[tex]\rm Surface \ area=\pi r(r+l)\\\\\rm Surface \ area=\pi 3(4+3)\\\\\rm Surface \ area=3\pi \times 7\\\\\rm Surface \ area=21\pi[/tex]
Hence, the total surface area of this cone is 21π square feet.

A force of 20,000 N is exerted for 5.00 s, on a 75,000 kg mass. What is the impulse of the force for this 5.00 s ?
Answer:
Check pdf
Step-by-step explanation:
The impulse of the given force is required.
The impulse of the force which is being exerted on an object of 75000 kg is 100000 Ns.
ImpulseF = Force exerted on a body = 20000 N
t = Time the force was exerted for = 5.00 s
When finding the impulse of a force the mass of the object the force is being applied to does not matter. The only thing that can affect the force is if another force is being applied by the object which here is not doing so.
Impulse is given by
[tex]J=Ft\\\Rightarrow J=20000\times 5.00\\\Rightarrow J=100000\ \text{Ns}[/tex]

What is the value of x?
Answer:x = 8.5
Step-by-step explanation:
1. Combine like terms
62+75+9 = 146
2.Set up equation
146+4x = 180
3. Subtract 146 to each side
146-146 + 4x = 180-146 = 34
4. Divide by 4
4x/4 = 34/4
X= 8.5
