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)

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

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.

Answer:

9/35

Step-by-step explanation:

To answer this question, you will need to find a common denominator.

The lowest common denominator between 7 and 5 is 35.

6/7 is equal to 30/35 and 3/5 is equal to 21/35

Use these numbers instead.

30/35 - 21/35 = 9/35

This number cannot be reduced any further, so it is the answer.

Answer:

9/35

Step-by-step explanation:

The length of one of the sides of the larger pentagon is 24 cm. The length of one of the sides of the smaller pentagon is 8 cm.

[tex]24[/tex]÷[tex]8=3[/tex]

So, if the larger pentagon is 3x the size of the smaller pentagon, we can find the area of the smaller pentagon by dividing the area of the larger pentagon by 3.

[tex]135[/tex]÷[tex]3=45[/tex]

The area of the smaller pentagon is 45in²

Answer:

The shorter piece is 28 inches

The long piece is 56 inches

Step-by-step explanation:

    First, we need to write an equation:

-> Let x be the shorter piece after they are cut.

84 inches = x + 2x

84 inches = 3x

28 inches = x

x = 28 inches

    Now we will find the length of each piece,

-> The shorter piece is 28 inches

         [] x = 28 inches

-> The long piece is 56 inches

         [] 2x = 2(28) = 56 inches

Checking work:

56 + 28 = 84

-> This solution should work

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.

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

[tex]P(3) = 0.027[/tex]
