Answer:
Width = 7, Length = 42
Step-by-step explanation:
Length is 6 times its width, means that it's the same number but times 6 so we'll use "x" for both length and width:
6x · x = 294
6x^2 = 294
divide both sides by 6
x^2 = 49
[tex]\sqrt{x^2}[/tex] = [tex]\sqrt{49}[/tex]
x = 7, width is 7 and length is 6(7) = 42

Answer: In the elimination method you either add or subtract the equations to get an equation in one variable. When the coefficients of one variable are opposites you add the equations to eliminate a variable and when the coefficients of one variable are equal you subtract the equations to eliminate a variable.

Does (2,-3) satisfies the equation 5x+3y=1
Answers
Answer: Yes
Step-by-step explanation: We're going to have to substitute
in the coordinates of that ordered pair into the equation.
I am going to substitute in the x and substitute in the y.
So it's really 5(2) + 3(-3) = 1.
From here it should be pretty straightforward,
all we are doing is evaluating the statement.
Simplifying on the left we have 10 + -9 = 1 or 1 = 1.
Now we know that the ordered pair (2, -3) satisfies this equation.

An Air Force plane left Paris and flew toward Moscow. A cargo plane left one hour later flying 40 km/h faster in an effort to catch up to it. After four hours the cargo plane finally caught up. What was the Air Force plane's average speed?
(Use box method)
Answers
Their is your answer hope i get a like
Answer:
The plane is traveling at 160 km/h
Step-by-step explanation:
This is because if the first plane is traveling at 160 and flies for 5 hours it'll travel 800 km. then the second plane will have to catch up in 4 hours since it left an hour late, this means traveling at 160 km with an extra 40 km in 4 hours will get it to the first plane at 800 km in the 4 hours given

Answer:
(1) 56 miles/hour
Step-by-step explanation:
We need to find the average rate of change from t = 2 to t = 9.
At t = 2 hours, d = 106 miles.
At t = 9 hours, d = 498 miles.
The average rate of change in function f(x) from x = a to x = b is
[f(b) - f(a)]/(b - a)
average rate of change from t = 2 to t = 9 =
(498 - 106)/(9 - 2) = 392/7 = 56
Answer: (1) 56 miles/hour

A manufacturer of running shoes knows that the average lifetime for a particular model of shoes is 15 months. Someone in the research and development division of the shoe company claims to have developed a longer lasting product. This new product was worn by 25 individuals and lasted on average for 17 months. The variability of the original shoe is estimated based on the standard deviation of the new group which is 5.5 months. Is the designer's claim of a better shoe supported by the trial results?
Answers
Answer:
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 15 \ months[/tex]
The sample size is n = 25
The sample mean is [tex]\= x = 17 \ months[/tex]
The standard deviation is [tex]s = 5.5 \ months[/tex]
Let assume the level of significance of this test is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu = 15[/tex]
The alternative hypothesis is [tex]H_a : \mu > 17[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n -1[/tex]
=> [tex]df = 25 -1[/tex]
=> [tex]df = 24[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{\= x- \mu }{\frac{s}{\sqrt{n} } }[/tex]
=> [tex]t = \frac{ 17 - 15 }{\frac{5.5}{\sqrt{25} } }[/tex]
=> [tex]t = 1.8182[/tex]
Generally from the student t distribution table the probability of obtaining [tex]t = 1.8182[/tex] to the right of the curve at a degree of freedom of [tex]df = 24[/tex] is
[tex]p-value = P(t > 0.18182 ) = 0.4286[/tex]
From the value obtained we see that [tex]p-value > \alpha[/tex] hence
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is no sufficient evidence to show that the designer's claim of a better shoe is supported by the trial results.
