An audiologist is testing a patient to determine the softest sound of a specific frequency that the patient reports hearing. She

begins with a 10 decibel (dB) sound for trial 1, then increases the volume by 2 dB for each trial after that. If the patient can hear all sounds of that frequency that have a volume louder than 26 dB, and t represents the trial numbers that the patient can hear, which of the following inequalities best models the situation described above?

Answer:

26 <t+2

Step-by-step explanation:

The volume has to be louder than 26 so the inequaltiy sign should be an x is greater than sign and the intervals increase by 2 so you can add 2 to each x.

Hope this helps!

15 even.

A good way to look at it is a clock. The 3 means 15 minutes and the 6 means 30 minutes.

6 divided by 3 = 2.

Hope this helps and makes sense!

Ben is making salsa.He needs 1/3 cups of chilies for each bach of salsa.Ben has 5/6 cup green chilies.How many baches of salsa c
FromTheMoon [43]

Answer:

The number of batches Ben can make with 5/6 cup of green chilies is 2\frac{1}{2} batches of salsa.

Step-by-step explanation:

From the question,

Ben needs 1/3 cups of chilies for a batch of salsa.

To determine how many batches of salsa he can make with 5/6 cup of green chilies,

Let the number of batches Ben can make with 5/6 cup of green chilies be x.

Now,

If 1/3 cups of green chilies is needed for 1 batch,

Then, 5/6 cups of green chilies will make x batches

1/3 × x = 5/6 × 1

x = 5/6 ÷ 1/3

x = \frac{5}{6} \div \frac{1}{3}

x = \frac{5}{6} \times \frac{3}{1}

x = \frac{15}{6}

x = \frac{5}{2}

x = 2\frac{1}{2}

Hence, the number of batches Ben can make with 5/6 cup of green chilies is 2\frac{1}{2} batches of salsa.

Solve for b in (y^-9)^b=y^45
ElenaW [278]
Y^-9 * b = y^45   Divide by y^-9
b = \dfrac{y^{45}}{y^{-9}}

The law of powers says that if you have the same base (y in this case) and two different powers that are divided, you can subtract the denominator from the numerator (in this case)

b = y^{45- - 9} = y^{54}
