P=12T

Q=66T

-----------

Toys added to each bag:

P=12T+nT

Q=66T+nT

Therefore, 66T+nT=3(12T+nT)

------------

66T+nT=36T+3nT

T(66+n)=T(36+3n)

66+n=36+3n

3n-n=66-36

2n=30

Therefore, n=30/2=15

In which function is x = 2 mapped to 32 ?
Nataly_w [17]

Answer:

Option 2 is the correct answer

g(x) = 4 {(x + 3)}^{2}  - 68

Step-by-step explanation:

g(x) = 4 {(x + 3)}^{2}  - 68 \\  \\  \because \: g(2) = 4 {(2 + 3)}^{2}  - 68  \\  = 4 {(5)}^{2}  - 68 \\  = 4(25) - 68 \\  = 100 - 68 \\  = 32

Steve provides lawn care services in his neighborhood. For each lawn he charges a flat fee of 6 dollars for clean up and 10 doll
Taya2010 [7]

Answer:

c(h) = 6 + 10h

Step-by-step explanation:

We are given the following in the question:

Flat fee = 6 dollars

Charges per hour = 10 dollars per hour

Let Steve work for h hours.

Then, we can write the total charge in the following manner:

Total charge =

=\text{Flat fee} + (\text{Number of hours}\times \text{Charges per hour})

Putting values, we get,

c(h) = 6 + 10h

is the required equation for total charges if Steve worked for h hours.

The digit 5 appears twice in the number 255,120. How does the total value of the 5 on the right compare to the total value of th
maksim [4K]

Answer:

The value of the first "5" in the number 255,\!120 is ten times that of the second "5\!" in this number.

Step-by-step explanation:

What gives the number "255,\!120" its value? Of course, each of its six digits has contributed. However, their significance are not exactly the same. For example, changing the first \verb!5! to \verb!6! would give 2\mathbf{6}5,\!120 and increase the value of this number by 10,\!000. On the other hand, changing the second \verb!5!\! to \verb!6!\! would give 25\mathbf{6},\!120, which is an increase of only 1,\!000 compared to the original number.

The order of these two digits matter because the number "255,\!120" is written using positional notation. In this notation, the position of each digits gives the digit a unique weight. For example, in 255,\!120\!:

\begin{array}{|r||c|c|c|c|c|c|}\cline{1-7}\verb!Digit!& \verb!2! & \verb!5! & \verb!5! & \verb!1! & \verb!2! & \verb!0!\\\cline{1-7}\textsf{Index} & 5 & 4 & 3 & 2 & 1& 0 \\ \cline{1-7} \textsf{Weight} & 10^{5} & 10^{4} & 10^{3} & 10^{2} & 10^{1} & 10^{0}\\\cline{1-7}\end{array}.

(Note that the index starts at 0 from the right-hand side.)

Using these weights, the value 255,\!120 can be written as the sum:

\begin{aligned}& 255,\!120\\ &= 2 \times 10^{5} + 5 \times 10^{4} + 5 \times 10^{3} + 1 \times 10^{2} + 2 \times 10^{1} + 0 \times 10^{0} \\&=200,\!000 + 50,\!000 + 5,\!000 + 100 + 20 + 0 \end{aligned}.

As seen in this sum, the first "5" contributed 50,\!000 to the total value, while the second "5\!" contributed only 5,\!000.

Hence: The value of the first "5" in the number 255,\!120 is ten times that of the second "5\!" in this number.
