For a car moving at a constant speed, the distance traveled varies directly with the time spent driving. If such a car travels 210 miles in 7 hours, how many
miles does it travel in 4 hours?

Answer:

Job A= 12hrs and Job B= 10hrs

Step-by-step explanation:

first u need to make 2 equations, with 2 variables and the pay per hour for both jobs and let the first equal to the total pay at the end of the week

5.7x + 7.3y = 141.4

then the 2nd equation, let it equal to the total hours worked:

x + y = 22

you then make one of the variables the subject of the formula:

x= 22 - y

and substitute that formula into the first equation you would've made:

5.7(22-y) + 7.3y = 141.4 in this instance you then solve for y:

where y= 10hrs

given that y=10 you can then substitute it into either of the 2 equations:

x+y=22

x= 22-y

x= 22 - 10

x= 12hrs

therefore stating that Blake worked 12 hrs at job A and 10 hrs at job B

Answer:

10 CDs

Step-by-step explanation:

First, let's round the cost of each CD to the nearest whole number.

The closest multiple of 7 to 75 is 77.

(If we were to do the actual calculations, 75/6.98 is 10.744.. and so on, so we can confirm he can buy no more than 10 CDs)

Considering the given expression and the numerical values, it is found that it's value is False.

The expression used in this question is given as follows:

[tex](x - y) \times 2 > y[/tex]

The values considered are x = 4 and y = 6, hence:

[tex](6 - 4) \times 2 > 6[/tex]

[tex]4 > 6[/tex]

Hence, it is a False expression, as 4 is less than 6.

The solution to f(x)=g(x) is 0. Therefore, option B is the correct answer.

Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.

Given that, f(x)=g(x)

f(x)=-(x+2)(x-2) and g(x)=2|x+2|

Now, -(x+2)(x-2)=2(x+2)

-(x-2)=2

x-2=-2

x=-2+2

x=0

Therefore, option B is the correct answer.

Total number of ways to arrange the given trees is equals to 24ways.

" Combination is defined as total number of ways arrangement made without considering the order."

Formula used

Fundamental principle of counting

First group has 'm' objects

second group has 'n' objects

Total number of ways objects can be arranged  =m × n

According to the question,

Number of oak trees = 3

Number of pines tree = 4

Number of maples trees = 2

Substitute the given values in the formula we get,

Total number of ways to arrange the given trees = 3 × 4 × 2

                                                                                  = 24ways

Hence, total number of ways to arrange the given trees is equals to 24ways.

The differentiation using the chain rule gives:

[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x) = \frac{1}{(kx)}*k = \frac{1}{x}[/tex]

Remember that:

[tex]ln(x) = \int\limits {\frac{1}{x} } \, dx[/tex]

Now, we want to derivate ln(kx) where k is a constant, the problem tells us to use the chain rule, so we define two functions:

Then we have:

g(f(x))

Remember that the chain rule says that:

[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x)[/tex]

In this case:

Then:

[tex]\frac{d(g(f(x)))}{dt} = g'(f(x))*f'(x) = \frac{1}{(kx)}*k = \frac{1}{x}[/tex]

The probability that the three people have chronic insomnia is the likelihood of people having chronic insomnia

The probability that the three people have chronic insomnia is 0.027

The proportion of people with chronic insomnia is given as:

p = 30%

Given that three people are selected, the probability that the three people have chronic insomnia is calculated as:

[tex]P(3) = p^3[/tex]

So, we have:

[tex]P(3) = (30\%)^3[/tex]

Evaluate the exponent
