A bus makes a stop 2:30 letting off 13 people and lettng on 8. The bus makes another stop ten minutes later to let off 3 more pe

Zigmanuir [339]

Answer:

The number of people on the bus after the second stop is 8 less than the number of peoples on the bus before the 2:30 stop.

Step-by-step explanation:

Let $P_0$ be the total number of peoples on the bus before 2:30 stop.

For the first stop at 2:30:

The bus let off 13 people, so, the total number of remaining people on the bus $= P_0-13$

again, the bus let on 8 people, so, the total number of people on the bus

$= P_0-13+8$

$=P_0-5$

For the second stop after 10 minutes (i.e at 2:40):

The bus let off 3 people, so, the total number of remaining people on the bus $= P_0-5-3$

$=P_0-8$

After the second stop, the number of people on the bus is $P_0-8$ , where P_0 number of peoples on the bus before 2:30 stop.

Hence, the number of people on the bus after the second stop is 8 less than the number of peoples on the bus before the 2:30 stop.

Answer:

$\sf A . \sf \frac{3}{-7}$

$\sf E. \sf -( \frac{-3}{-7} )$

This above options makes the expression true.

The negatives above can be distributed up as well, which happened in A.

In E, when the negatives inside the bracket cancels out, the negative outside the brackets multiplies and makes the expression true.

In B the expression turns positive, thus false same happens with C and D

What is the second step in sketching the graph of a rational function?

Elodia [21]

Answer:

C. Choosing test numbers to the left and right of each of the function's zeros and finding the value of the function at each test number

Step-by-step explanation:

Rational function: In mathematics, the term "rational function" is determined as any specific function that can be described through any "rational fraction", in other words, an algebraic fraction, involving both the denominator and the numerator are considered as polynomials. Therefore, the coefficients of specific polynomials are ought not to be in rational numbers and can be considered in the K field.

In the question above, the given statement represents option C is correct.

cestrela7 [59]

Answer:

11 coins for $1.99

Step-by-step explanation:

The maximum total less than $2 is $1.99. It takes 11 coins to make that total. It would take 1 fewer if the nickel were not required.

Starting with the minimum required coins, which total $0.91, we need to add $1.08 using a minimum number of coins. To minimize the added coins, we start with the largest we can use without going over the total: 2×50¢ + 1×5¢ + 3×1¢. These 6 coins added to the required 5 coins give the desired total using 11 coins.

11 coins: $1.99 . . . . (3×50¢ +1×25¢ +1×10¢ +2×5¢ +4×1¢)

$1.99 is the highest possible total less than $2.00, and it takes a minimum of 11 coins to make that total.
