Jennifer has a pocketful of change all in nickels and quarters. There are 11 coins with a total value of $1.15. Which system of

equations can you use to find the number of each type of coin?
n + q = 11
n + q = 1.15

n + q = 11
5n+25q= 1.15

5n +25q =11
n + q = 1.15

n + q = 11
0.05n + 0.25q = 1.15

Answer:

n + q = 11

0.05n + 0.25q = 1.15

Step-by-step explanation:

Hi, to answer this question we have to write a system of equations:

n = number of nickel coins

q = number of quarter coins

Since there are 11 coins, the sum of the number of nickels and quarters must be 11:

n+q =11

Since:

1 nickel = $0.05

1 quarter = $0.25

The total value (1.15) must be equal to the product of the number of nickels (n) and the value of each nickel in dollars (0.05); plus the product of the number of quarters (q) and the value of each quarter in dollars (0.25)

0.05n + 0.25q = 1.15

The system is ;

n + q = 11  

0.05n + 0.25q = 1.15

What is the distance between point R (−1, 7) and point T (−7, 7) ?
zepelin [54]
You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units

UNO [17]

Answer:

See explanation

Step-by-step explanation:

Consider given statement "If a figure is a cube, then it has eight vertices" in math terms. Let

  • statement p be "A figure is cube.";
  • statement q be "A figure has 8 vertices."

Then the statement  "If a figure is a cube, then it has eight vertices"  can be written as

p\Rightarrow q

Converse (q\Rightarrow p): If a figure has eight vertices, then it is a cube.

Inverse (\neg p\Rightarrow \neg q): If a figure is not a cube, then it has not eight vertices.

Contrapositive (\neg q\Rightarrow \neg p): If a figure has not eight vertices, then it is not a cube.

The equation d=3t represents the relationship between the distance (d) in inches that a snail is from a certain rock and the tim
Maksim231197 [3]

Answer:

3 minutes

Step-by-step explanation:

d=3t is our formula.

d being the distance (9 inches for this problem)

t is the time in minutes


Substituting our known information would make our equation look like:

9 = 3t

to solve for t we divide both sides of the equation by 3

9/3 = 3t/3

3 = t


So if a snail travels 3 inches per minute, it will have traveled 9 inches in 3 minutes.
