it is (C) because the line is ZERO meaning the line is vertical and since it goes through 5, it is y=5 cuz u always have the formula for slope; y=mx+b and since there is o x intercept you just stick with the y intercept which is 5 so long story short, it is y=5 (c)

Rob has $1.65 in nickels and dimes. He has 25 coins in all. How many of each kind of coin are there? Please explain how you got your answer and show your work.

Answers

Answer:

The number of nickels is 17 and number of dimes is 8.

Step-by-step explanation:

Let the number of nickels be x and number of dimes be y.

Total number of coins is 25.

x+y=25                   .... (1)

\$1=100\text{ cents}

1\text{ nickel}=5\text{ cents}

1\text{ dimes}=10\text{ cents}

5x+10y=1.65*100

5x+10y=165                     .... (2)

On solving (1) and (2), we get

5x+10(25-x)=165

-5x+250=165

-5x=-85

x=17

Put this value in equation 1.

17+y=25

y=8

Therefore the number of nickels is 17 and number of dimes is 8.

Final answer:

Rob has 15 nickels and 10 dimes. This conclusion is reached via a system of equations, considering both the number of coins and the total worth in cents.

Explanation:

This problem can be solved using a system of equations. Let's denote the number of nickels as n and the number of dimes as d. We have two equations here:

  1. The total number of coins is 25. So, n + d = 25.
  2. A nickel is worth 5 cents and a dime is worth 10 cents. So, the total amount in cents is 165. So, the equation considering the worth of each coin is 5n + 10d = 165.

From equation [1], we can express d in terms of n (d = 25 - n) and substitute it into equation [2] to find the value of n.

Doing this, we find that  n = 15, which means d = 10. So, Rob has 15 nickels and 10 dimes.

Figure ABCD has vertices A(−2, 3), B(4, 3), C(4, −2), and D(−2, 0). What is the area of figure ABCD?

Answers

Answer:

The area of figure ABCD is:

                    24 square units.

Step-by-step explanation:

We see that the given points form the vertices of a trapezium ABCD with bases AD and CB with measure,

AD= 3 units

and CB=5 units

and the height of the trapezium is: AB= 6 units.

Hence, the area of trapezium ABCD is:

Area=(1)/(2)* (AD+CB)* AB\n\n\nArea=(1)/(2)* (3+5)* 6\n\n\nArea=(1)/(2)* 8* 6\n\n\nArea=24

         Hence, the area of figure ABCD is:

           24 square units.
