Answer:
Second, Hour, and Millisecond
Step-by-step explanation:
An hour is 60 full minutes
A second is 60 milliseconds
1 Hour = 60 min
1 min = 60 seconds
1 sec = 60 milliseconds
1 millsec = 60 microseconds
1 microsec = 60 nanoseconds
1 nanosec = 60 picoseconds

6w-19 + k when
w=8 and k = 2
Answer:
31.
Step-by-step explanation:
1. Write out the problem.
6w-19 + k; w=8 and k=2
2. Figure out the first part of the problem.
So, if w=8 and 6 and w are next to each other, we should multiply 6*8, which is 48. Next, it says to subtract 19. 48-19=29.
3. Find out what the last part of the problem is.
Since the first part of the problem is 29 and k=2, we should add 29+2=31, which is the final answer.

Which statement is true? A. A sample statistic can never be equal to the population parameter. B. Point estimates are defined for both samples and populations. C. To calculate a sample proportion, we need to know the population size. D. To calculate a point estimate, we need to know the sample size.
Answer: A) A sample statistic can never be equal to the population parameter.
Step-by-step explanation:
The statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.
The following statements should not be considered:
The statistic of the sample should be equal to the parameter of the population as the statistic represent the attribute of the sample and the parameter represent the parameter of the population. Also, each and every sample should have an equivalent chance of using it. The estimation of the point does not define the sample & population as the estimation of the point should be predicted for the parameter of the population.For determining the point estimate, the sample size does not need as the population is required.Therefore we can conclude that the statement "In order to determine the sample proportion, we have to measure the size of the population" is correct.

Answer:
C
Step-by-step explanation:
SA=pi*r^2+pi*r*s
SA=3.14*3^2+3.14*3*8
SA=3.14*9+3.14*24
SA=103.62
SA= about 104 inches
Aubrey included the base (you can't put on a hat that has a bottom), the right work should be:
SAhat=pi*r*s
SAhat=3.14*3*8
SAhat=3.14*24
SAhat=75.36
SAhat= about 75

2. Solve this problem: There will be 460 people at the sport's award banquet. If each table seats 8 people, how many tables are needed?
A. 3,680 tables
B. 57 tables
C. 58 tables
D. 452 tables
Answer:
C. 58 tables
Step-by-step explanation:
If there are 460 people, and each table seats 8 people, then we divide 460 by 8, giving us 57.5 tables. We cannot have a half of a table, so the answer is 58 tables.

Answer:
-4, -24
Step-by-step explanation:
The location of Z is either +10 or -10 units away from Y, since YZ = 10. Then Z could be located at either -4 or -24.
Answer:
-4, -24 are the two possible locations of Z
Step-by-step explanation:
Z's location could be ten to the left of -14 or ten to the right of -14. -4 is ten to the right and -24 is ten to the left of Z.

Initially, there were only 86 weeds in the garden. The weeds grew at a rate of 29% each week. The following function represents the weekly weed growth: f(x) = 86(1.29)x. Rewrite the function to show how quickly the weeds grow each day.
Please help me!!!!
Answer:
f(x) = 86(1.04)x; grows approximately at a rate of 0.4% daily
Step-by-step explanation:
The base of the exponential function is 1.29 for 7 days, as in
f(x) = 86*(1.29)^x
The new rate for days can be calculated by dividing x by 7 (where x remains the number of weeks), namely
f(x) = 86*1.29^(x/7)
Using the law of exponents, b^(x/a) = b^(x*(1/a)) = (b^(1/a))^x
we simplify by putting b=1.29, a=7 to get
f(x) = 86*(1.29^(1/7))^x
f(x) = 86*(1.037)^x since 1.29^(1/7) evaluates to 1.037
Rounding 1.037 to 1.04 we get a (VERY) approximate function
Answer:f(x) = 86(1.04)x

What is the logarithmic function?In mathematics, the logarithmic function is an inverse function to exponentiation. The logarithmic function is defined as
For x > 0 , a > 0, and a ≠1,
y= logₐ x if and only if x = a^y
Then the function is given by
f(x) = logₐx
Given here log x= 3 ⇒x=10³
⇒x=1000
Hence, The value of x must be equal to 1000

If x, y, and z are positive integers such that 6xyz+30xy+21xz+2yz+105x+10y+7z=812, find x+y+z.
Answer:
[tex]x+y+z \Rightarrow 2+2+6 = 10[/tex]
Step-by-step explanation:
First we have to factor the equation:
[tex]6xyz+30xy+21xz+2yz+105x+10y+7z=812[/tex]
The commom factor of first three terms and [tex]105x[/tex] is [tex]3x[/tex]. Note that [tex]105x=3x(35)[/tex]
[tex]3x(2yz+10y+7z+35)+2yz+10y+7z=812[/tex]
[tex]3x(2yz+10y+7z+35)+(2yz+10y+7z)=812[/tex]
In order to have two equal factors add 35 both sides:
[tex]3x(2yz+10y+7z+35)+(2yz+10y+7z+35)=847[/tex]
Let's factor [tex](2yz+10y+7z+35)[/tex]
[tex](2yz+10y+7z+35) \Rightarrow 2y\left(z+5\right)+7\left(z+5\right) \Rightarrow \left(z+5\right)\left(2y+7\right)[/tex]
Now we have:
[tex]3x(z+5)\left(2y+7\right)+\left(z+5\right)\left(2y+7\right)=847[/tex]
[tex](3x + 1) (2y + 7) (z + 5) = 847[/tex]
Now it is the interesting part: You have to figure out that 3 numbers multiplied by each other will result in 847.
We have [tex]847 = 7 \cdot 11 \cdot 11[/tex]
Let's try
[tex]2y+7=7\\2y=0[/tex]
I will stop right here. This is not true.
Let's try then
[tex]2y+7=11\\2y=4\\y=2[/tex]
Now let's try
[tex]z+5 = 11\\z=6[/tex]
Now let's try
[tex]3x+1=7\\3x=6\\x=2[/tex]
Note that in this case I didn't considered [tex]3x+1=11[/tex] because it would not be an integer.
Therefore,
[tex]x+y+z \Rightarrow 2+2+6 = 10[/tex]

Noah says:
I am thinking of a number,
When I subtract 17 and
multiply the answer by
8, I get 32.
What is Noah's number?
Answer:

You subtract 17 (x - 17) and multiply the answer by 8 (8(x - 17)). This is equal to 32. Solve for x
8(x - 17) = 32
8x - 136 = 32
8x = 168

The area of rectangle ABCD is 9 cm2 show that x2 +5x=3
Answer: x² + 5x = 3
Step-by-step explanation:Step-by-step explanation:
The rectangle has been divided into a square and three rectangles.
The area of
a square = (x)(x) = x²
a rectangle #1 = (2)(x) = 2x
a rectangle #2 = (3)(x) = 3x
a rectangle #3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore we have the equation:
x² + 2x + 3x + 6 = 9 subtract 6 from both sides
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
The equation is proven.
What is an area?Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
The rectangle has been divided into a square and three rectangles.
The areas are;
square = (x)(x) = x²
rectangle 1 = (2)(x) = 2x
rectangle 2 = (3)(x) = 3x
rectangle 3 = (2)(3) = 6
The area of a large rectangle is the sum of the square area and three rectangles, and is 9 cm². Therefore, we have the equation:
x² + 2x + 3x + 6 = 9
x² + 5x + 6 - 6 = 9 - 6
x² + 5x = 3
Hence, proved.
