Are the two terms on each tile like terms? Sort the tiles into the appropriate categories.

o-na [289]

Answer:

Like terms: $-7y^2$ and $y^2$ , $0.5kt$ and $-10kt$ , $6$ and $9$

Not like terms: $-4p$ and $p^2$ , $5x$ and $5$ , $3ad$ and $2bd$

Step-by-step explanation:

Two or more terms are called like terms if they have same variables and powers.

$-7y^2$ and $y^2$ are like terms because they have same variable y with same power 2.

$-4p$ and $p^2$ are not like terms because they have same variable y with different powers.

$0.5kt$ and $-10kt$ are like terms because they have same variables kt with same power 1.

$6$ and $9$ are like terms because both are constant.

$5x$ and $5$ are not like terms because one have variable and other is constant.

$3ad$ and $2bd$ are not like terms because they have different variables.

Like terms: $-7y^2$ and $y^2$ , $0.5kt$ and $-10kt$ , $6$ and $9$

Not like terms: $-4p$ and $p^2$ , $5x$ and $5$ , $3ad$ and $2bd$

A transformer increases the input voltage from 12V to 12,000V. What is the ratio of the number of wire turns on the primary coil

erma4kov [3.2K]

Answer:

$\frac{n_p}{n_s}=\frac{1}{1000}$

Step-by-step explanation:

Given voltage of primary coil is $V_p=12V$

And voltage of secondary coil is $V_s=12,000V$

A transformer is a device that contains primary and secondary coil. These coils are mounted on soft iron. The change in voltage depends upon the number of turns of primary coil $(n_p)$ and secondary coil $(n_s)$ .

Following equation represents the relation between them.

$\frac{V_s}{V_p} =\frac{n_s}{n_p}\\\\\frac{12,000}{12}=\frac{n_s}{n_p}\\\\1000=\frac{n_s}{n_p}$

Then, ratio of the number of wire turns on the primary coil to the number of turns on the secondary coil is

$\frac{n_p}{n_s}=\frac{1}{1000}$

5<br>X Х please find the answer<br>20

Daniel [21]

Answer:

2 or 4

Step-by-step explanation:

Since I do not quite understand what you mean by X X, I could think of two answers. If you are doing 5 times X=20, then X = 4, but if you are trying to do 5 times x times x, then x=2.
