Answer:
Yes
Step-by-step explanation:
Yes, the difference in composition and quantity from the blubber of baby dolphins in comparison to that of adults allows them to regulate and maintain their body temps much more efficiently. This in term allows baby dolphins to have a much higher probability of survival as opposed to if their blubber was the same as adults. Once they reach a certain age the composition begins to change since they are able to more easily adapt to their environment.

What is the value of x?
Answer:
135°
Step-by-step explanation:
here's your solution
=> we know that , sum of all angles is
equal to 180°
=> hence ,we have two angles
=> 1st angle = 45°
=> 2nd angle = 9x + 18
=>. adding both angle
=> 45° + 9x + 18° = 180°
=> 63° + 9x = 180°
=> 9x = 180° - 63
=> 9x = 117°
=>. x = 117/9
=> x = 13°
=>. hence, the required angle = (13*7) + 18°
=> angle = 135°

Directions: For a spinning amusement park ride, the velocity v in meters per second of a car moving around a curve with a radius r meters is given by the formula v= √ar, where a is the car’s acceleration in m/s2.
1. For safety reasons, a ride has a minimum acceleration of 39.2 m/s2. If the cars on the ride have a velocity of 14 m/s what is the smallest radius that any curve on the ride may have?
2. What is the acceleration of a car moving at 8m/s around a curve with a radius of 2.5m?
Answer:
1. r = 5 m 2. a = 25.6 m/s²
Step-by-step explanation:
The relation between the velocity, the radius of path and the acceleration on the circular path is given by :
[tex]a=\dfrac{v^2}{r}[/tex]
1. Acceleration, a = 39.2 m/s²
Velocity of the car, v = 14 m/s
The radius of the path can be calculated using the above formula i.e.
[tex]r=\dfrac{v^2}{a}\\\\r=\dfrac{(14)^2}{39.2}\\\\r=5\ m[/tex]
2. Velocity of the car, v = 8 m/s
The radius of the path, r = 2.5 m
The acceleration of the car is given by :
[tex]a=\dfrac{8^2}{2.5}\\\\a=25.6\ m/s^2[/tex]
Hence, this is the required solution.

[tex] \sqrt{27[/tex]
Answer:
It's irrational
Step-by-step explanation:
the square root of 27 is equal to:
[tex]\sqrt{27} = \sqrt{3\cdot3\cdot3} = 3\sqrt{3}[/tex]
We know that [tex]\sqrt{3}[/tex] is an irrational number (but a real number), so [tex]3\sqrt{3}[/tex] is the same.
In case we need to prove that [tex]\sqrt{3}[/tex] is irrational, please leave a comment.

Answer:
The dimensions of the real store are 80 times bigger as per scale:
1.875 in * 80 = 150 in = 150/12 ft = 12.5 ft2.25 in * 80 = 180 in = 180/12 ft = 15 ftThe area of the real store:
150 in * 180 in = 27000 in²12.5 ft * 15 ft = 187.5 ft²Is the relationship between x and y proportional? Show and explain your answer

Answer:
Yes
Step-by-step explanation:
Being proportional means that if you divide the Y value by the X number for each ordered pair, they all equal the same number
For this case, this is proportional because you need to multiply by 6 to get the Y value.
Find the distance d between 21 = (-7 - 6i) and Z2 = (-15 – 12i). Express your answer in exact terms and simplify, if needed.
Answer:
10
Step-by-step explanation:
The distance is equal to the modulus of Z1-Z2.
[tex]Z_1 - Z_2 = -7 - 6i - (-15 - 12i) = 8 + 6i\\|8 + 6i| = \sqrt{8^2 + 6^2} = \sqrt{64 + 36} = \sqrt{100} = 10[/tex]

what are common prime factor of 77 and 242?
Answer:
2 times 11 times 3511
Step-by-step explanation:
i kinda dont know what your asking but i tried
The common prime factor of the numbers 77 and 242? will be 11.
What is a prime factor?A number can be expressed as the product of its prime factors through the process of prime factorization. A number with exactly two factors, 1 and the number itself, is said to be a prime number. As an illustration, let's use the number 30. Even though we are aware that 30 = 5 6 is not a prime number,
Given that the numbers are 77 and 242. The prime factor of the numbers is calculated as,
77 / 11 = 7
242 / 11 = 22
Hence, the number 11 is completely dividing both the numbers 77 and 242 so the prime factor of the numbers is 11.

A person enters the room.
The mean age of the 6 people is now 25.
What is the age of the person who entered the room?
Answer:
57 years
Step-by-step explanation:
total=25*6=150
17+21+15+15+25+x=150
93+x=150
x=150-93
x=57
Answer:
age=57
Step-by-step explanation:
ages=17 21 15 15 25 ?
17+21+15+15+25=93(old mean)
17+21+15+15+25+?=25(new mean)

Jamal spent _ 3 4 of his allowance. On the number line, label the fraction that represents the part that Jamal spent. Explain
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Fraction of pocket money spent by Jamal = 3/4
The number line is divided into 4 equal parts with distance between successive tick marks representing 1 of the whole = (1/4). Hence, 3/4 of the whole would mean 3 portions of the total 4 portions of the number line represents the amount spent by Jamal.
The fraction spent by Jamal is also labeled on the number line picture in the attached document.
find the missing angle measure of the following figure
Answer:
Step-by-step explanation:
By triangle sum theorem,
73°+ 39° + m∠1 = 180°
m∠1 = 180° - 102°
m∠1 = 78°
Since, m∠1 = m∠2 [Vertically opposite angles]
m∠2 = 78°
Sum of interior angles of a polygon = (n - 2)×180°
Where n = number of sides of the polygon
Sum of the interior angles of a quadrilateral = (4 - 2)×180°
= 360°
Therefore, 77° + m∠3 + 90° + m∠2 = 360°
77° + m∠3 + 90° + 78° = 360°
m∠3 = 360° - 245°
m∠3 = 115°
