Tiger cubs are around 2 years old when they leave their mothers. In the wild, tigers live about 11 years. About what percent of their lives do tigers spend with their mothers
Answer:
18.18%
Step-by-step explanation:
Cross-multiply
11 years ------------ 100% of life
2 years ------------- x% of life
11/2 = 100/x ===> 11x = 2*100 ===> 11x = 200 ===> x = 200/11 ===> x = 18.18%
Which line is perpendicular to a line that has a slope
of - 1/3
line MN
line AB
line EF
line JK
For this case we have to by definition, if two lines are perpendicular then the product of its slopes is -1, that is:
[tex]m_ {1} * m_ {2} = - 1[/tex]
So, if we have the slope [tex]m_ {1} = - \frac {1} {3}[/tex]
A perpendicular line will have a slope m_ {2}:
[tex]m_ {2} = \frac {-1} {m_ {1}}\\m_ {2} = \frac {-1} {- \frac {1} {3}}\\m_ {2} = 3[/tex]
Thus, the perpendicular line will have slope [tex]m_ {2} = 3[/tex]
Answer:
The perpendicular line will have slope [tex]m_ {2} = 3[/tex]

What is 3/8 x 4 3/6 x 4
Final answer:
To solve both 3/8 x 4 and 3/6 x 4, we multiply the numerator by 4 and simplify the resulting fraction if necessary, resulting in 1.5 for the first expression and 2 for the second.
Explanation:
To solve the problem 3/8 x 4 and 3/6 x 4, we need to perform multiplication of a fraction by a whole number. For the first part, we multiply the numerator (3) by the whole number (4) and keep the denominator (8) to get 12/8, which simplifies to 1 1/2 or 1.5. For the second part, we simplify the fraction 3/6 to 1/2 since both the numerator and denominator can be divided by 3. Then, again, we multiply the numerator (1) by the whole number (4) and keep the denominator (2), resulting in 4/2, which simplifies to 2.

Here diameter = 12 , hence r = 12 ÷ 2 = 6, thus
A = π(6²)
All of the following must be true statements except:
m∠RPS = m ∠WPR
m∠RPS + m∠ SPU= 180
m∠ SPT = m∠ UPT
We need to find the false statement.
The first one is true (m<RPS=m<WPR because RU⊥SW).
The second statement is true because the two angles make a linear pair and are supplementary.
The third one is false because we only know that the angle pair is complimentary. Their measures are not equal.
answer: m∠SPT=m∠UPT

Is {-2, 1} a solution set to X squared take away 2X Takeaway three equals X take away one
Answer:
No! {-2, 1} is not a solution set to the given equation.
Step-by-step explanation:
The statement X squared take away 2X Takeaway three equals X take away one can be written in mathematical terms as follows:
X² - 2X - 3 = X - 1
⇒ X² - 2X - 3 - X + 1 =0
⇒ X² - 3X - 2 = 0
Now, substitute x= -2 and see if the equation is satisfied.
⇒ (-2)² -3(-2) - 2 = 4 + 6 - 2
= 8 ≠ 0
So, -2 is not a solution to the equation.
Now, check for x = 1.
⇒ (1)² - 3(1) - 2 = 1 - 3 - 2
= -4 ≠ 0
⇒ x = 1 is not a solution as well.

Find the first five terms of the recursive sequence.
The first five terms of sequence is 4.5, -27, 162, -972, 5832
Solution:
Given that we have to find first five terms of recursive sequence
Given sequence is:
[tex]a_n = -6a_{n - 1}[/tex]
To find first five terms, substitute n = 2, 3, 4, 5
First term is given = [tex]a_1[/tex] = 4.5
Find second term:
Substitute n = 2 in given sequence
[tex]a_2 = -6a_{2 - 1}\\\\a_2 = -6a_1\\\\a_2 = -6(4.5) = -27[/tex]
Thus second term of given sequence is -27
Find third term:
Substitute n = 3 in given sequence
[tex]a_3 = -6a_{3-1}\\\\a_3 = -6a_2\\\\a_3 = -6(-27) = 162[/tex]
Thus third term of given sequence is 162
Find fourth term:
Substitute n = 4 in given sequence
[tex]a_4 = -6a_{4-1}\\\\a_4 = -6a_3\\\\a_4 = -6(162) = -972[/tex]
Thus fourth term of given sequence is -972
Find fifth term:
Substitute n = 5 in given sequence
[tex]a_5 = -6a_{5-1}\\\\a_5 = -6a_4\\\\a_5 = -6(-972) = 5832[/tex]
Thus the first five terms of sequence is 4.5, -27, 162, -972, 5832
A srtaight line l has the equation of 2y-6x=-8 what is the gradient of l
Answer:
gradient = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the gradient and c the y- intercept )
Rearrange 2y - 6x = - 8 into this form
Add 6x to both sides
2y = 6x - 8 ( divide all terms by 2 )
y = 3x - 4 ← in slope- intercept form
with gradient m = 3
In the video, I drop a ball off a three-story balcony. We know that objects in freefall follow the equation for height h, in
meters, h = – 4.9t' + c, where t is time in seconds, and is the initial height. A student timed the drop at 1.27
seconds.
Use this to determine the height from which the ball was dropped, to at least 2 decimal places.
Answer:
The initial height from which the ball was dropped = 7.90 meters
Step-by-step explanation:
The correct question is:
In the video, I drop a ball off a three-story balcony. We know that objects in free fall follow the equation for height h, in meters, [tex]h = -4.9t^2 + c[/tex], where [tex]t[/tex] is time in seconds, and [tex]c[/tex] is the initial height. A student timed the drop at 1.27 seconds.
Use this to determine the height from which the ball was dropped, to at least 2 decimal places.
Solution:
The height [tex]h[/tex] of the free falling ball is represented by the equation as:
[tex]h=-4.9t^2+c[/tex] where [tex]t[/tex] is time in seconds, and c is the initial height.
To determine the initial height from which the ball was dropped.
The drop was timed at 1.27 seconds, we will plugin [tex]t=1.27[/tex] in the given height function to find [tex]h(1.27)[/tex]
[tex]h(1.27)=-4.9(1.27)^2+c[/tex]
[tex]h(1.27)=-7.90+c[/tex]
Since, the drop is timed at 1.27 seconds, so in the given time the ball will reach the ground, making [tex]h(1.27)=0[/tex]
So, we have.
[tex]0=-7.90+c[/tex]
Adding both sides by 7.90 to solve for [tex]c[/tex].
[tex]0+7.90=-7.90+7.90+c[/tex]
[tex]7.90=c[/tex]
∴ [tex]c=7.90\ m[/tex]
Thus, the initial height from which the ball was dropped = 7.90 meters

The initial amount of water in the tank was 1600 liters.
Let's denote the initial amount of water in the tank as W.
First, two-fifths of the water are used, leaving [tex]\(\frac{3}{5}\)[/tex] of the water remaining.
[tex]\[\text{Remaining amount} = \frac{3}{5} \times W\][/tex]
Then, three-quarters of the remaining water are used, leaving \(\frac{1}{4}\) of the remaining water.
[tex]\[\text{Final amount} = \frac{1}{4} \times \left(\frac{3}{5} \times W\right)\][/tex]
According to the problem, the final amount is 240 liters:
[tex]\[\frac{1}{4} \times \left(\frac{3}{5} \times W\right) = 240\][/tex]
Now, solve for W:
[tex]\[\frac{3}{5} \times W = 240 \times 4\][/tex]
[tex]\[\frac{3}{5} \times W = 960\][/tex]
[tex]\[W = \frac{960 \times 5}{3}\][/tex]
[tex]\[W = 1600\][/tex]
So, the initial amount of water in the tank was 1600 liters.

William works at a nearby electronics store. He makes a commission of 6% percent on everything he sells. If he sells a computer for $764.00, how much money does William make in commission?
Commission earned by William is $ 45.84
Solution:Given that,
William makes a commission of 6% percent on everything he sells
He sells a computer for $764.00
To find: Commission amount of William
Given that he makes a commission of 6 % on everything he sells. So he has received a commission of 6 % of $ 764.00
Commission amount of William = 6 % of $ 764.00
a % of b can be written in fraction as [tex]\frac{a}{100} \times b[/tex]
[tex]6 \% \text { of } 764=\frac{6}{100} \times 764=0.06 \times 764=45.84[/tex]
Thus commission earned by William is $ 45.84

A boat traveled 504 miles downstream and back. The trip downstream took 14 hours. The trip back took 21 hours. What is the speed of the boat in still water? What is the speed of the current?
Answer:
The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.
Step-by-step explanation:
Let's say b is the speed of the boat in still water, and c is the speed of the current.
Distance = rate × time
Going downstream:
504 = (b + c) × 14
36 = b + c
Going upstream:
504 = (b − c) × 21
24 = b − c
Two equations, two variables. Solve with substitution or elimination. To use elimination, add the equations together.
60 = 2b
b = 30
Plug into any equation to find c.
36 = b + c
36 = 30 + c
c = 6
The speed of the boat in still water is 30 mph, and the speed of the current is 6 mph.
The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.
What is the solution to the equation?The distribution of weights to the variables involved that establishes the equilibrium in the calculation is referred to as a result.
Let the speed of the boat in still water be x and the speed of water be y.
A boat traveled 504 miles downstream and back. The trip downstream took 14 hours. Then the equation will be
x + y = 504 / 14
x + y = 36 ...1
The trip back took 21 hours. Then the equation will be
x - y = 504 / 21
x - y = 24 ...2
Add equations 1 and 2, then the value of x will be
2x = 36 + 24
2x = 60
x = 30 miles per hour
Then the value of y will be
30 - y = 24
y = 6 miles per hour
The speed of the boat in still water will be 30 miles per hour and the speed of the current will be 6 miles per hour.

what is the value of x if Lines 1 and 2 are parallel? LINE 1: (-2,5) and (0,0) LINE 2: (x,12) and (-3,2)
Answer:
x=-7
Step-by-step explanation:
The value of x if, Lines 1 and 2 are parallel, LINE 1: (-2,5) and (0,0) LINE 2: (x,12) and (-3,2) is -7.
What is line?An object having an endless length and no width, depth, or curvature is called a line. Since lines can exist in two, three, or higher-dimensional environments, they are one-dimensional things.
Given:
Line 1 and line 2 are parallel,
The coordinates of lines are given as,
LINE 1: (-2, 5) and (0, 0) LINE 2: (x, 12) and (-3, 2)
As we know that the slope of the parallel lines is equal,
Calculate the slope of Line 1 as shown below,
Slope = 0 - 5 / 0 - (-2)
Slope = -5 / 2
Thus, for the second line,
The slope of Line 2 = (2 - 12) / (-3 - x)
-5 / 2 = -10 / -3 - x
-5(-3 - x) = -20
15 + 5x = -20
5x = -20 - 15
x = -35 / 5
x = -7
