Yes, Lulu was associated to one of the cubs. Cub #711 because It was discovered it in data set 5 for her parentage.
Why is genetics needed for lion research?They discovered that there is evident genetic evidence of current population fragmentation, which occurs when teams of a species are isolated from each other, by trying to compare the DNA of lions presently to lions from 100 years ago.
This fragmentation could have a long-term effect on the iconic species' genetic health.
What were the advantages for Lulu (#630) in raising the cubs who were not hers?Raising the children together has an evolutionary advantage because it makes sure that Lulu's genetic data is passed down.
Because her cub is one of many, there is safety in numbers.

) Find the value of x.

44°
Step-by-step explanation:
remember, the sum of all angles in a triangle is always 180°.
and the sum of all angles around a single point on one side of a line is also always 180° (because that line is like a diameter of any circle with that point as center, and half a circle is 180°).
3)
the third inner angle of the triangle is
180 = 63 + 51 + angle = 114 + angle
angle = 66°.
x = 180 - 66 = 114°
4)
the third inner angle of the triangle is
180 = 86 + 45 + angle = 131 + angle
angle = 49°
x + 30 = 180 - 49 = 131°
x = 101

c. between 4 and 5
d. between 64 and 125
We have to plot the square roots of the numbers 70, 85, 99, and 112 between 64 and 125 ( d )
First, we must evaluate the square root of given numbers.
√70 = √ ( 2 × 5 ×7 ) = 8.36
√85 = √ ( 5 × 17 ) = 9.22
√99 = √( 9 × 11 ) = 3√11 = 9.95
√112 = √( 4 × 4 × 7 ) = 4 √7 = 10.58
All these numbers ( 8.36, 9.22, 9.95 , 10.58 ) belong between, square roots of √64 and √125 which are 8 and 15. So we have to put these numbers in between the square roots of 64 and 125 on the number table.

The recommended mass of a Soccer ball is 0.43 kilogram. The actual mass is allowed
to vary by up to 20 grams.
a. Write and solve an absolute value equation to find
the minimum and maximum acceptable soccer ball
masses.
b. A soccer ball has a mass of 423 grams. The soccer
ball loses 0.016 kilogram of mass over time. Is the
mass now acceptable? Explain.
The absolute value equation is:
|M - 430g| = 20g
And the solutions are M = 410g and M = 450g
b) No, the mass is not acceptable.
How to write the absolute value equation?We know that the recomended mass is 0.43kg, with an accepted error of 20 grams.
Where:
0.43kg = 0.43*1000g = 430g
Then the minimum mass accepted is: 430g - 20g = 410g
The maximum mass accepted is: 430g + 20g = 450g
These are the solutions, and the absolute value equation is, if M is the mass:
|M - 430g| = 20g
b) If the ball has a mass of 423g it is in the accepted range, if now it loses 0.016kg:
0.016kg = 0.016*1000g = 16g
The new mass is:
423g - 16g = 407g
This is smaller than the minimum accepted mass, then this mass is not acceptable.

Randy's swimming coach kept track of his average 50-meter lap times during the first 3 weeks of training. How much greater was the percent of change from Week 1 to Week 2 than from Week 2 to Week 3? Round to the nearest tenth of a percent.
The percent of the first change is greater by 2.36%.
Time in 1st week = 28.8 sec
Time in 2nd week = 27.6 sec
Time in 3rd week = 27.1 sec
∴ Change of time from week 1 to week 2 = (28.8 - 27.6) sec
= 1.2 sec
∴ Percent of change from week 1 to week 2 = [tex]\frac{time change}{1st week time} \times 100[/tex] %
= [tex]\frac{1.2}{28.8} \times 100[/tex] %
= 4.17%
∴ Change of time from week 2 to week 3 = (27.6 - 27.1) sec

∴ Percent of change from week 2 to week 3 = [tex]\frac{Time change}{2nd week time} \times 100[/tex] %

5
times longer than Giulio to reach this goal.
They both use the same bank that provides a 5
5
% annual interest rate compounded quarterly.
Work out how long it takes Hiroshi to reach his investment goal?
Give your answer correct to the nearest year.
It takes Hiroshi 30 years to reach his investment goal.
The formula for calculating the amount received on the principal amount (P) after t years at r% rate of interest is-
Amount = P(1 + r/100)^t
Let the principle amount with Hiroshi be P
then, the amount that Giulio starts with = 3P
Let time period for Giulio's investment = t
Then, the time period for Hiroshi's investment = 5t
Rate = 5%
As the investment goals of both the people are equal, they will get the same amount.
Therefore, we get the following equation-
P(1 + 20/100)^5t/4 = 3P(1 + 20/100)^t/4
(1 + 20/100)^5t/4 = 3(1 + 20/100)^t/4
[(1 + 20/100)^5t/4] /[(1 + 20/100)^t/4] = 3
(1 + 20/100)^(5t/4- t/4) = 3
(1 + 20/100)^(4t/4) = 3
(1 +0.2)^t = 3
(1.2)^t = 3
Taking log on both sides-
Log (1.2)^t = log 3
t log 1.2 = log 3
t = log 3/ log 1.2
t = 6.025
Time taken by Hiroshi to reach his investment goal = 5t
= 5(6.025)
= 30.128
Thus, it takes Hiroshi 30 years to reach his investment goal.

Area of rectangle:
Area of rectangle means the area covered by the rectangle.
The formula for area of rectangle is

where,
l is the length of the rectangle
b is the breadth or width of the rectangle
Given,
A rectangular plot of land measures 40.0 m by 120.0 m, with a parcel 10.0 m by 12.0 m out of one corner for an electrical transformer.
Here we need to find the remaining area of the rectangular plot land.
For that first, we have to find the area of each separately,
Like,
The area of the rectangular plot is,
A₁ = 40.0 x 120.0 m²
A₁ = 4800m²
Similarly, the area of the electric transformer is,
A₂ = 10.0 x 12.0 m²
A₂ = 120m²
Now the remining area is,
A = A₁ - A₂
A = 4800 - 120 m²
A = 4680m²
Therefore, the area of the remaining rectangular plot is 4680m².

For example we can consider a prism having 12-sided regular polygons as bases because then there would be 2 bases and 12 lateral sides for a total of 14 sides for the polyhedron.
Since the lateral faces are rectangles and not 12-sided polygons like the bases, the polyhedron is an irregular polyhedron.
