A collection of 19 coins consisting of nickels and dimes is worth $1.35. How many dimes are there
pshichka [43]

Answer:

There are 8 dimes there.

Step-by-step explanation:

This question is solved used a system of equations.

I am going to say that:

x is the number of nickels.

y is the number of dimes.

19 coins

This means that x + y = 19.

A nickel is worth $0.05. A dime is worth $0.1. The total of these coins is $1.35. So

0.05x + 0.1y = 1.35

How many dimes are there?

We have to find y.

From the first equation: x = 19 - y.

Replacing in the second:

0.05(19 - y) + 0.1y = 1.35

0.95 - 0.05y + 0.1y = 1.35

0.05y = 0.4

y = 0.4/0.05

y = 8

There are 8 dimes there.

Describe the zero vector (the additive identity) of the vector space. P3 (No Response) (No Response) x (No Response) x2 (No Resp
blsea [12.9K]

Answer:

\mathbf{0+0x+0x^2+0x^3}

Step-by-step explanation:

Zero vector are those vectors whose norm is zero and whose direction and direction are undefined. However, they are vector, which posses zero length and no particular direction.

It is the vector of coordinates (0,0). Or, it is defined as the vector of length or zero modulus. The definition of a zero vector is a useful mathematical convention for solving vector equations. It plays the role of the neutral element for the addition of vectors. In a sense, it is an anomaly because it has no direction or meaning, but it is handy from the point of view of vector algebra.

From the question given :

The additive identity of the zero vector in the vector space can be written as:

\mathbf{0+0x+0x^2+0x^3}
