Answer:

50% of 3000

Step-by-step explanation:

49% is very close to 50% (half).  3,025 pounds is very close to 3,000 pounds.

Half of 3,000 pounds is 1,500 pounds.

Solve for b:<br><br> 6b+14 = -7-b
vladimir2022 [97]

Answer:

b = -3

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

6b+14=−7−b

6b+14=−7+−b

6b+14=−b−7

Step 2: Add b to both sides.

6b+14+b=−b−7+b

7b+14=−7

Step 3: Subtract 14 from both sides.

7b+14−14=−7−14

7b=−21

Step 4: Divide both sides by 7.

\frac{7b}{7} = \frac{-21}{7}

b= -3

For a map a scale of 2 inches to 70 miles is used. If the distance on the map measures 1.8 inches what is the actual distance
asambeis [7]

Answer:

63 miles

Step-by-step explanation:

2/70 = 1.8/x                           Cross multiply

2x = 70 * 1.8                          Combine

2x = 126                                Divide by 2

x = 126/2

x = 63

The actual distance is 63 miles.

I have no idea where to start on either of these problems. Would someone explain the steps to me? My teacher hasn’t gone over th
bazaltina [42]

Answer:

Problem 9:  -1/2

Problem 10:  1/5

Step-by-step explanation:

Problem 10:  Label the given ln e^(1/5) as y = ln e^(1/5).

Write the identity e = e.  Raise the first e to the power y and the second e to the power 1/5 (note that ln e^(1/5) = 1/5).  Thus, we have:

e^y = e^(1/5), so that y = 1/5 (answer).


Problem 9:    Let y = (log to the base 4 of) ∛1 / ∛8, or

                            y = (log to the base 4 of) ∛1 / ∛8, or

                             y = (log to the base 4 of) 1 /2

Write out the obvious:              

                            4                                   =   4

Raise the first 4 to the power y and raise the second 4 to the power (log to the base 4 of) 1 /2.  This results in:

                              4^y    =     1/2.  Solve this for y.  

                                 Note that 4^(1/2) = 2, so that 4^(-1/2) = 1/2

Thus, y = -1/2
