AnswerA,B,C

Step-by-step explanation:

A is right , using the exponet property, it turns into $x^{1/5}$ to the 7 power which equal x to the 1.4 th power. Using the product of power, $x^{1/5}$ to the 7th power is the same as 1/5 times 7 which equal 1.4. so b is right .Using the fractioal exponet rule C is also right as 5th root of x to the 7th power is the same as to the 7 power divided by 5 which 1.4 so c is right

x + 2y = 21

+ -x + 3y = 29

--------------------------

5y = 50

y = 10

x + 2(10) =21

x = 1

6x + 6y = 30

+ 15x - 6y = 12

-------------------------------

21x = 42

x = 2

6(2) + 6y = 30

6y = 18

y = 3

Find the value of t needed to make the equation shown true. 25t = 12.5

-Dominant- [34]

Answer:

1/2

Step-by-step explanation:

Hi Avahosel2020!

To find the value of $t$ we need to simplify the equation:

25 $t$ = 12.5

To just get $t$ , we must divide 25 on both sides:

$\frac{25t}{25}$ = $\frac{12.5}{25}$

We can move the decimal one spot over and add a 0 to the denominator:

$\frac{25t}{25}$ = $\frac{125}{250}$

$t$ = $\frac{125}{250}$

Simplifying!

$\frac{125}{250}$ = $\frac{1}{2}$ .

Thus, $t$ has the value of $\boxed{\frac{1}{2} }$ .

What happens to the energy not output by a machine

Sveta_85 [38]

Answer:

By using the energy conservation law, the input energy must be equivalent to the output energy. If you measured output energy is lower than your input energy, you have lost that difference of energy either in mechanical inefficiency (friction, heat, etc.) or an energy sink.

Thus, the energy not output by the machine is lost in the process within the machine.

Cheers.
