B) In y = 25x, the value of y is 25 times the value of x, and in y = x + 25, the value of y is 25 more than the value of x.

Out of all the answer choices, b makes the most sense.

25x can be translated as 25 times x.

x + 25 can be translated as 25 more than a number.



Hope this helps!

There are 20 members of a basketball team.
spin [16.1K]

Answer:

a)125970

b)95040

c)35640

Step-by-step explanation:

a) selecting 12 player from 20 players can be one in ^{20} C_{12}

 ^{20} C_{12} = \frac{20!}{12!X (20-12)!}

          =  \frac{20!}{12!X8!}

          = 125970

b) since each position has an identity permutations can be used so

   Number of ways = ^{12} P_{5}

                                = \frac{12!}{(12-5)!}

                                = \frac{12!}{7!}

                                = 95040

c) coach permutes 4 players for position other than centers in  ^{12}P_{4} ways and selects center in 3 ways

  so, number of ways = ^{12}P_{4}X3

                                     =\frac{12!}{8!}X3

                                     =35640

What is the value of expression of -5 square -3
Elanso [62]

Answer:

-0.008

Step-by-step explanation:

Hi there,

When you have a negative exponent, it tells us how many times to multiply the reciprocal of the base. For example, this problem tells us to multiply the reciprocal of -5 (which is -\frac{1}{5}) three times since the exponent is -3. As a final solution, you should get -0.008.

Hope this explanation helps. Cheers.

If a sprinkler waters 1 over 15 of a lawn in 1 over 3 hour, how much time will it take to water the entire lawn?
Feliz [49]
Now, a whole, will be 15/15 or 1 whole.

now, the sprinkler does 1/15 of the lawn in 1/3 of an hour, how long will it be to do the whole 15/15?

\bf \begin{array}{ccll}
lawn&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
\frac{1}{15}&\frac{1}{3}\\\\
\frac{15}{15}&h
\end{array}\implies \cfrac{\quad \frac{1}{15}\quad }{\frac{15}{15}}=\cfrac{\quad \frac{1}{3}\quad }{h}\implies \cfrac{1}{15}\cdot \cfrac{15}{15}=\cfrac{\quad \frac{1}{3}\quad }{\frac{h}{1}}
\\\\\\
\cfrac{1}{15}=\cfrac{1}{3}\cdot \cfrac{1}{h}\implies \cfrac{1}{15}=\cfrac{1}{3h}\implies 3h=15\implies h=\cfrac{15}{3}\implies h=5
