The expression (2.3)⁵ is equivalent to 2.3 x 2.3 x 2.3 x 2.3 x 2.3

Brrunno [24]2 years ago
4 0

Step-by-step explanation:

2.3 \times 2.3 \times 2.3 \times 2.3 \times 2.3 will be equivalent to 2.3^{5}.

2.3^5 is a shorted way of saying 2.3 multiplied by itself 5 times.

<u>Solving:</u>

<u />2.3 \times 2.3 \times 2.3 \times 2.3 \times 2.3

5.29 \times 2.3 \times 2.3 \times 2.3 Equivalent.

12.167 \times 2.3 \times 2.3 Equivalent.

27.9841 \times 2.3 Equivalent.

64.36343 Equivalent.

Simplify completely. (w^15/w^5)^4 <br> HELP PLEASE
Umnica [9.8K]

Answer:

w^{40}

Step-by-step explanation:

To simplify recall exponent rules:

1. An exponent is only a short cut for multiplication. It simplifies how we write the expression.

2. When we multiply terms with the same bases, we add exponents.

3. When we divide terms with the same bases, we subtract exponents.

4. When we have a base to the exponent of 0, it is 1.

5. A negative exponent creates a fraction.

6. When we raise an exponent to an exponent, we multiply exponents.

7. When we have exponents with parenthesis, we apply it to everything in the parenthesis.

We will use these rules to simplify.

Use rule #3 to simplify inside the parenthesis first.

\frac{w^{15}}{w^5}  = w^{10}

Now simplify the exponent of 4 using rule 6.

(w^{10})^4 = w^{40}

A plumber charges an initial fee of $200 plus and hourly fee of $50. Mrs. Coombs paid the plumber $ 450. How many hours did the
nikitadnepr [17]

Answer:

5 hours

Step-by-step explanation:

The total cost is the fee plus the hours* hourly cost

450 = 200+50*h  where h is the hours

Subtract 200 from each side

450-200 = 200-200 +50h

250 = 50h

Divide each side by 50

250/50 = 50h/50

5 = h

5 hours

What is the value of y in the relative frequency table? Round the answer to the nearest percent.
Ulleksa [173]
Given a relative frequency table is made from data in a frequency table.

Frequency Table
               G                    H              Total
E            12                   11                23

F            14                    8                 22

Total       26                   19                45

Recall that the relative frequency table is obtained from the Frequency table by dividing each entry of the frequency table by the ovarall total of the frequency table.

Thus the relative frequency table of the frequency table above is given by:

Relative Frequency Table
                        G                                       H                                  Total
E         12/45 = 0.27 = 27%          11/45 = 0.24 = 24%       23/45 = 0.51 = 51%

F         14/45 = 0.31 = 31%          8/45 = 0.18 = 18%        22/45 = 0.49 = 49%

Total    26/45 = 0.58 = 58%         19/45 = 0.42 = 42%      45/45 = 1.00 = 100%

For the given relative frequency table with the missing value y being the value of the relative frequency of E and G.

Therefore, the value of y is 27%
