A wave travels 1/3 mile in 1/20 hour. At this rate, how far will the wave travel in 1 hour?
A wave will travel 6.7 mile in 1 hour.
Given that,
A wave travels 1/3 mile in 1/20 hour.
How to calculate the distance in given time?
To calculate the value of distance at time is given as,
Distance = Speed X Time
To given condition wave travels 1/3 mile in 1/20 hour,
We calculate,
⇒ [tex]\frac{1}{3}[/tex] ÷ [tex]\frac{1}{20}[/tex]
Divide a fraction by multiplying its reciprocal,
⇒ [tex]\frac{20}{3}[/tex]
⇒ [tex]6.66667[/tex]
⇒[tex]6.7[/tex] mile
So a wave will travel 6.7 mile in 1 hour.

Three roots of the polynomial equation x^4 - 4x^3 - 2x^2 + 12x + 9 = 0 are 3, -1, and -1. Explain why the forth root must be a real number. Find the forth root.
Hello,
This polynomial function has maximum 4 roots as the degree is 4
and their coefficients are all reals so if one root is a complex number, its conjugate is a root too.
As we know already 3 roots and none of them is a complex number, the fourth one is a real number
And their product is 9 = 3 * 1 * (-1) * (-3) as
[tex](x-x_1)(x-x_2)(x-x_3)(x-x_4)=x^4+...+x_1x_2x_3x_4[/tex]
(The constant term is 9, the product of the roots)
so the last root is -3

What does -3/8 > −1 indicate about the positions of -3/8 and −1 on the number line?
-3/8 is located on the right of 0, and −1 is located on the left of 0
-3/8 is located on the left of 0, and −1 is located on the right of 0
-3/8 is located on the left of −1
-3/8 is located to the right of −1
Answer:
D
Step-by-step explanation:
because -3/8 is also a neg- so both answers would be on the left of (0) but -3/8 would be closer to (0) than 1 so that means it would be on the right of 1

Answer:
28cm
Step-by-step explanation:
ive done this question before
Answer:
28 cm
Step-by-step explanation:
This is the answer because:
Perimeter = L + W + L + W
Area = L x W
1) Since the shape is a square, there has to be two of the same factors that multiply.
_ x _ = 49
2) We know 7 x 7 = 49, therefore, w just have to add 7 + 7 + 7 + 7 which equals 28 cm
Therefore, the answer is 28 cm

4. Population.
5. Sample.
Step-by-step explanation:
1. Statistical Inference: Reasoning from a sample to a population. For example, the average common entrance score of all examinees (population l) in New York city or a business that collects data from a random sample of 100 consumers and recorded whether they are male or female.
2. Variability: Successive observations of a system or phenomenon do not produce exactly the same result. For instance, the distribution having the same value of mean can have varying variability.
3. Outlier: An observation that differs considerably from the main body of the data. For example, in the following scores 1, 2, 3, 4, 50, 5, 60; both 50 & 60 is an outlier.
4. Population: The entire collection of objects or outcomes about which data are collected. For example, the number of new born babies in a hospital, the total number of football players in a soccer league.
5. Sample: A subset of the population containing the observed objects or outcomes and the resulting data from these objects or outcomes. For example, the average height of girls in a class having a population of 10 boys and 20 girls.
how do you convert 12 over 100 to a percentage
Answer:
12%
Step-by-step explanation:
A percent is any fraction with 100 as a denominator. So [tex]\frac{12}{100}[/tex] is the same as 12% and 4 over 100 is the same as 4%
Here's an easy was to remember, there are 100 pennies to make a dollar that like per-CENT it's out of 100.
Hope that helps and have a great day!
Answer:
12%
Step-by-step explanation:
your question isn't giving me an option to answer but do 12 divided by 100 and you get a decimal, then multiply it by 100 which will give you the percentage. In this case is would be 12%

Solve the following equation - 2(x-8)=18-3(5x+6)
Answer:
-2(x-8)=18-3(5x+6)
-2x+16=18-15x-18
-2x+15x=18-18+16
13x=16
X=16/13
Answer:
[tex]x=-\frac{16}{13}[/tex]
Step-by-step explanation:
[tex]-2(x-8)=18-3(5x+6)[/tex]
Start by distributing [tex]-2[/tex] into [tex](x-8)[/tex], and [tex]-3[/tex] into [tex](5x+6)[/tex]:
[tex]-2x+16=18-15x-18[/tex]
Combine like terms:
[tex]-2x+16=-15x[/tex]
Subtract [tex]16[/tex] from both sides of the equation:
[tex]-2x=-15x-16[/tex]
Add [tex]15x[/tex] to both sides of the equation:
[tex]-13x=16[/tex]
Divide both sides of the equation by the coefficient of [tex]x[/tex], which is [tex]-13[/tex]:
[tex]x=-\frac{16}{13}[/tex]
the sum of the first 10 terms of an AP is four times the sum of the first 5 terms then the ratio of the first term to the common difference is
Answer:
The ratio of the first term to the common difference is 1 : 2
Step-by-step explanation:
The rule of the sum of the AP is
[tex]S_{n}=\frac{n}{2}[2a+(n-1)d][/tex] , where
a is the first number
d is the common difference
n is the position of the number
∵ [tex]S_{10}[/tex] = 4 × [tex]S_{5}[/tex] ⇒ (1)
→ Find [tex]S_{10}[/tex] and [tex]S_{5}[/tex]
∵ In [tex]S_{10}[/tex] n = 10
∴ [tex]S_{10}=\frac{10}{2}[2a+(10-1)d][/tex]
∴ [tex]S_{10}=5[2a+9d][/tex]
∴ [tex]S_{10}[/tex] = 10a + 45d ⇒ (2)
∵ In [tex]S_{5}[/tex] n = 5
∴ [tex]S_{5}=\frac{5}{2}[2a+(5-1)d][/tex]
∴ [tex]S_{5}=2.5[2a+4d][/tex]
∴ [tex]S_{5}[/tex] = 5a + 10d ⇒ (3)
→ Substitute (2) and (3) in (1)
∵ 10a + 45d = 4[5a + 10d]
∴ 10a +45d = 20a + 40d
→ Subtract 40d from both sides
∴ 10a + 45d - 40d = 20a + 40d - 40d
∴ 10a + 5d = 20a
→ Subtract 10a from both sides
∴ 10a - 10a + 5d = 20a - 10a
∴ 5d = 10a
→ Divide both sides by 5
∴ d = 2a
→ That means d is twice a or a is half d
∴ a : d = 1 : 2
The ratio of the first term to the common difference is 1 : 2

What is the solution to
3x + 7 = x + 13 ?
Answer:
x = 1.5
or
x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
First, move +7 to the other side of equation on the answer side and change it to it's absolute (in this case I mean negative) value:
3x + x = 13 - 7
Next, Simplify the equation:
4x = 6
Finally, Celebrate! You just (hopefully) learned how to solve this!
x = 1.5

How many possible solutions are ther to a linear equation in one variable
Answer:
Step-by-step explanation:
Every linear equation that is a conditional equation has one solution. However, not every linear equation in one variable has a single solution. There are two other cases: no solution and the solution set of all real numbers. resulting value on the right side will always be one greater than the value on the left side.
