If the flea is to the left of zero and the absolute value of its location is 3.6, where on the number line is it?
Answer:
I JUST HAD THIS QUESTION AND I GOT 3/3, THE ANSWERS -3.6 BECAUSE THE ANSWER HAS TO BE TO THE LEFT OF THE ZERO, AND THE NUMBER IS 3.6, SO IF ITS TO THE LEFT AND THATS THE NUMBER THEN ITS -3.6 PERIODDDDD
Step-by-step explanation:
Answer:
If the flea is to the left of zero and its absolute value is 3.6, it means that the flea is located at a negative value on the number line. Since the absolute value of its location is 3.6, we can deduce that the flea is located at -3.6 on the number line.

A random sample of n = 16 scores is obtained from a parent population with σ = 12. If the sample mean is 6 points greater than the population mean, what is the z-score for the sample mean?
Answer:
0.5
Step-by-step explanation:
Sample mean, x = 6 points greater than population mean ;
Population mean, m = 16
Standard deviation, s = 12
Zscore = (sample mean - population mean) / standard deviation
Zscore = (x - m) / s
x = 16 + 6 = 22
Zscore = (22 - 16) / 12
Zscore = 6 /12
Zscore = 0.5

a cubical box has the dimensions 6 in x 3 in 7 in how many cubes with the dimensions of 3 in x 4 in x 2 in can be fitted into the cubical box
Answer:
5 1/4 cubes
Step-by-step explanation:
Volume of the cubical box = length × width × height
= 6 in x 3 in × 7 in
= 126 in³
Volume of the cube = length × width × height
= 3 in x 4 in x 2 in
= 24 in³
how many cubes with the dimensions of 3 in x 4 in x 2 in can be fitted into the cubical box
= Volume of cubical box / Volume of the cube
= 126 in³ / 24 in³
= 5 1/4 cubes

Step-by-step explanation:
Factorize using suitable identity
a²-(b-c)²
Step-by-step explanation:
We have,
a ^2 −(b−c) ^2
Since, x ^2 −y ^2 =(x+y)(x−y)
Thus,
⇒[a−(b−c)][a+(b−c)]
⇒(a−b+c)(a+b−c)
Hence, this is the answer.

help AB and CD are straight lines find z
Answer: z=16
Step-by-step explanation:
Angles on a straight line add up to 180.
As AB is a straight line we can use that to help us find z.
So you would do 68+85+11=164 (I got the 11 from the angle trapped between like C and F as opposite angles are the same).
Then you would do 180-164=16
So z=16

if 8^y = 16^x + 2 what is the value of Y
Answer:
y= -8
Step-by-step explanation:
8^y = 16^(y+2)
//to solve make the base equal, both 8 and 16 are powers of (2
(2^3)^y = (2^4)^(y+2)
//simplify, remember when doing this multiply the powers
2^3y = 2^(4y+8)
// now we can just make the 2 powers equal
3y = 4y+8
0=y+8
y= -8
check:
8^(-8) = 16^(-6)
2^(-24) = 2^(-24)

whats the answer to 5+ -5
Answer:
The answer is Zero.
Step-by-step explanation:
Adding a negitive 5 to a positive 5 cancels out
Answer:
0
Step-by-step explanation:
It's a negative five, meaning that if you are adding it, the number will still go back.
You made $5, but you're in debt of $5. So even though it is supposed to go up, it goes down back to 0 due to the debt, which is the negative.

A sample of 600 g of radioactive lead-210 decays to polonium-210 according to the function A(t) = 600e ^-0.032t, where t is time in years. Find the amount of radioactive lead remaining after
(a) 3 yr
(b) 8 yr
(c) 15 yr
(d) find the half-tie
round to the nearest integer as needed.
The amount of radioactive lead remaining after 3 years is 545gm.
The amount of radioactive lead remaining after 8 years is 464gm.
The amount of radioactive lead remaining after 15 years is 371gm.
The half-tie for radio active lead is 21.66 years.
Given that,
A sample of 600 g of radioactive lead-210 decays to polonium-210,
According to the function A(t) = 600e ^-0.032t,
Where, t is time in years.
We have to find,
Find the amount of radioactive lead remaining after.
According to the question,
Function [tex]A(t) = 600e^{(-0.032t)}[/tex]
After 3 years the amount of radioactive lead,[tex]A(3) = 600\times e^{(-0.032t)} \\\\A (3) = 600 \times \dfrac{1}{e^{0.032\times 3} } \\\\e^{0.096} = 1.10075\\\\A (3) = 600 \times \dfrac{1}{e^{0.096} } \\\\A (3) = 600 \times \dfrac{1}{1.10075} } \\\\A(3) = \dfrac{600}{1.10075}\\\\A(3) = 545gm[/tex]
The amount of radioactive lead remaining after 3 years is 545gm.
After 8 years the amount of radioactive lead,[tex]A(8) = 600\times e^{(-0.032t)} \\\\A (8) = 600 \times \dfrac{1}{e^{0.032\times 8} } \\\\e^{0.0256} = 1.129175\\\\A (8) = 600 \times \dfrac{1}{e^{0.0256} } \\\\A (8) = 600 \times \dfrac{1}{1.129175} } \\\\A(8) = \dfrac{600}{1.129175}\\\\A(8) = 464gm[/tex]
The amount of radioactive lead remaining after 8 years is 464gm.
After 15 years the amount of radioactive lead,
[tex]A(15) = 600\times e^{(-0.032t)} \\\\A (15) = 600 \times \dfrac{1}{e^{0.032\times 15} } \\\\e^{0.48} = 1.61607\\\\A (8) = 600 \times \dfrac{1}{e^{0.48} } \\\\A (8) = 600 \times \dfrac{1}{1.61607} } \\\\A(8) = \dfrac{600}{1.61607}\\\\A(8) = 371gm[/tex]
The amount of radioactive lead remaining after 15 years is 371gm.
The half-tie for radioactive lead,[tex]A(15) = 600\times \dfrac{1}{2} = 600e^{-0.032t} \\\\= e^{(-0.032t)} = \dfrac{1}{2}\\\\Taking \ log \ on \ both \ sides\\\\= -0.032t = ln2\\\\= t = \dfrac{ln2}{-0.032}\\\\= t = 21.660\\\\= t = 21.66 years[/tex]
The half-tie for radio active lead is 21.66 years.

A hike starts at an elevation of 13 and four-fifths feet below sea level and ends at an elevation that is 1,542 feet higher. How high is the hiker, in feet, above sea level at the end of the hike?
Answer:
the height above the seal level at the end of the hike is [tex]1528 \frac{1}{5} feet[/tex]
Step-by-step explanation:
The computation is shown below:
[tex]= 1542 - 13 \frac{4}{5}\\\\= 1542 - \frac{69}{5}\\\\= \frac{7710-69}{5} \\\\= \frac{7641}{5}\\\\= 1528 \frac{1}{5} feet[/tex]
