Answer:

Q=\frac{40}{y-16}

Q=10

Step-by-step explanation:

Let the quotient be represented by 'Q'.

Given:

The difference of a number 'y' and 16 is y-16

Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is y-16. So, we divide both these terms to get an expression for 'Q'.

The quotient of 40 and y-16 is given as:

Q=\frac{40}{y-16}

Now, we need to find the quotient when y=20. Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,

Q=\frac{40}{20-16}\\Q=\frac{40}{4}=10

Therefore, the quotient is 10, when the value of 'y' is 20.

Brett has 2 1/2 pounds of bird seed left to share equally among 4 bird cages in his pet shop. How many pounds can he put in each
Ksju [112]

Answer:

Brett can put \frac{5}{8}  = 0.625 pounds in each bird cage.

Step-by-step explanation:

The total amount of bird seed left = 2\frac{1}{2} pounds

=\frac{5}{2} pounds

Number of birds in pet shop  = 4

So, the share of each bird = \frac{\textrm{Total available seeds}}{\textrm{Total number of birds in the pet shop}}

= \frac{\frac{5}{2} }{4}  = \frac{5}{2}  \times \frac{1}{4}  = \frac{5}{8}

Hence, Brett can put  \frac{5}{8}   = 0.625 pounds in each bird cage.

A scientist counts 25 bacteria present in a culture and finds that the number of bacteria triples each hour. The function y = 25
Ksju [112]
y = 25\cdot~3^x\\ \\ 1170 = 25\cdot~3^x\\ \\ \frac{1170}{25} = 3^x\\ \\ \frac{243}{5} = 3^x\\ \\ log\ \frac{243}{5} = log~3^x\\ \\ log~243-log~5=x~log~3\\ \\ 
 log~3^5-log~5=x~log~3\\ \\ 5~log~3-log~5 = x~log~3\\ \\ 5(0,48)-0,70= 0,48x\\ \\ 2,4-0,7 = 0,48x\\ \\ 1,7=0,48x\\ \\ x=\frac{1,7}{0,48}\\ \\ \large{\boxed{x=3,54\ h}}

I need help with 16a and 17. i haven't been able to understand this in class and no one was able to help me
kompoz [17]
16a. 21cm. bc when it has 10 grams it  moves half of that to 5cm so divide 42 by 2 and you get 21cm

17. remember y=mx+b; m is slope and b is y-intercept
you have to put your equation from point slope to y=mx+b
4x+y=6 
subtract 4x from each side
y=-4x+6
slope = -4
y-intercept= 6

hope this helped :)
