Danica made $319 babysitting last month. In the that month, She babysat for a total of 29 hours. How much money did Dianica make per hour?

Answer:

135.58 just did this

Step-by-step explanation:

First, I calculated the amount of money he got on Monday. I multiplied. 8.50 x 7 which equals 59.50. Then, I calculated the amount of money he got on Tuesday. I multiplied 8.50 (since that is the number of money he gets paid) to 3.2 (since that’s the amount of hours he works). I got 27.200. Then lastly, I calculated the amount of money he got on Friday. So first I changed 5 3/4 into a decimal. This is 5.75. After, I multiplied 8.50 x 5.75, and got 48.8750.lastly, I added and got 135.575. So if you round it, it will be 135.58

From the question we are told that

52% is the birthrate of Girls

Therefore

       [tex]\frac{52}{100} =0.52[/tex]

Step-by-step explanation:

Answer:

Michelle needs to pay $88.56 to pay for her purchase, including tax.

Step-by-step explanation:

The purchasing cost of a pair of jeans = $35

The purchasing cost of dress = $47

The total purchase cost = $35 + $47

                                        = $82

Given that the store charges 8% sales tax on all purchases.

Thus,

Tax amount  = 8% × 82

                      = 8/100 × 82

                      = 0.08 × 82

                      = 6.56

The total cost including the tax = Tax amount + The total purchase cost

                                                    = 6.56 + 82

                                                    = $88.56

Therefore, Michelle needs to pay $88.56 to pay for her purchase, including tax.

Answer:

C. The triangles are not similar

Step-by-step explanation:

For two triangles to be considered similar, the 3 angles of one triangle must be equal or congruent to the corresponding 3 angles of the others.

The only angle in ∆BCG that is equal to the corresponding angles in ∆EFG is <BGC. The remaining 2 angles in ∆BCG are not congruent to the corresponding 2 angles in ∆EFG.

Therefore, we can conclude that both triangles are not similar.

Answer:

Step-by-step explanation:

B.If Rick walks 0 miles, he will raise $60.

E.

For each mile that Rick walks, he will raise an additional $60.

The total amount raised by Rick in the walk-a-thon is shown by the expression y = 60 + 60x.

Given that,
Rick will participate in a walk-a-thon to raise money for charity. The amount he will raise based on the number of miles he walks is shown in the table, which represents a linear function amount raised is to be determined.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
Let the total amount raised be y,
Amount raised per x mile is 60x,
And initial raise = 60
Total raise = y = 60 + 60x

Thus, the total amount raised by Rick in the walk-a-thon is shown by the expression y = 60 + 60x.

Answer:

Option A: 17,18,19 is the right answer.

Step-by-step explanation:

Let x be the first integer then the next two consecutive integers will be x+1, x+2

According to the given statement, the equation will be:

[tex]x + (x+1) + (x+2) = 54[/tex]

The equation is a linear equation in one variable, we have to solve the equation to get the values of integers

[tex]x+x+1+x+2 = 54\\3x+3 = 54\\3x = 54-3\\3x = 51\\\frac{3x}{3} = \frac{51}{3}\\x = 17[/tex]

Second integer = x+1 = 17+1 = 18

Third integer = x+2 = 17+2 = 19

The three integers are: 17,18 and 19

The general solution of the given differential equation

[tex]y = ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]

Step-by-step explanation:

Step(I):-

Given differential equation

                                   y⁴+18y"+81y=0

                         ⇒    (D⁴+18D²+81)y =0

The auxiliary equation

                               [tex]m^4+18m^2+81 =0[/tex]

                              [tex](m^2)^{2} + 2 (9) m^{2} +(9)^2 = 0[/tex]

        we will use formula  ( a + b)² = a² + 2 a b + b²    

                  ⇒    ( m² + 9 ) ² = 0

                   ⇒    ( m² + 9 ) ( m² + 9 ) = 0

                      [tex]m^{2} =-9\\m= - 3i and m=3i[/tex]

            m² + 9 = 0      

      [tex]m² = -9\\m= -3i and m=3i[/tex]

The complex roots are   0± 3 i ,0 ± 3 i

Step(ii):-

The complementary function  

              [tex]y = e^{\alpha x } ( c_{1} + c_{2} x ) cos\beta x + ( c_{3} +c_{4} x) sin\beta x[/tex]

The general solution of the given differential equation

          [tex]y = e^{0 x } ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]

The general solution of the given differential equation

   [tex]y = ( c_{1} + c_{2} x ) cos3 x + ( c_{3} +c_{4} x) sin3 x[/tex]    





Answer:

The inverse function is:

{(1,8), (2,-1), (5,10), (-3,-3)}

Step-by-step explanation:

When a function is represented in the form of ordered pairs, the first element of each ordered pair is the input and the second element in each ordered pair is the output. In the inverse of a function the input becomes output and the output becomes input.

Given function is:

{(8,1), (-1,2), (10,5), (-3,-3)}

Reversing the order of elements of ordered pairs will given us the inverse function.

The inverse function is:

{(1,8), (2,-1), (5,10), (-3,-3)}

The probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.

The likelihood or chance of an event occurring is measured by probability. Usually, it is stated as a number between 0 and 1, where 0 denotes an event's impossibility and 1 denotes its certainty.

There are 10 balls in total, and 2 of them are basketballs. So the number of balls that are not basketballs is 10 - 2 = 8.

Of these 8 balls, we know that 1 is a softball. So the number of balls that are either a softball or not a basketball is 1 + 8 = 9.

Therefore, the probability of grabbing a ball that is either a softball or not a basketball is:

P(softball or not a basketball) = 9/10

So the probability of grabbing a ball that is either a softball or not a basketball is 9/10, or 0.9 when expressed as a decimal.

Answer:

first, second and fourth

Step-by-step explanation:

If you use distribution,

6a(5+d) is the same as  

6a(5) + 6a(d)

Multiplied =  30a + 6ad

So it's the 1st 2nd and fourth choice.

1st is stated above when multiplied out and combined.

2nd is after distribution.

4th choice is basically combination of 1 and 2 where one is combined (first term) and the second one just set up to be multiplied.

It cannot be third because you are multiplying the factors and not adding so you cannot have 11a.

It cannot be last choice because you have different types of terms that cannot be combined (one with a alone and one with ad)

Answer:

(6a*5) + (6a*d)

30a + 6ad

30a + (6a*d)
