Answer:

The answer is $1250

Step-by-step explanation:

Solution,

Principle (P) = $ 5,000

Time (T) = 5 years

Rate(R) = 5 %

Simple Interest (I) = ?

Now,

We have,

Simple Interest (I) = P×T×R/ 100

= 5,000×5×5/100

= $1250

A pot is being used to boil off 1 kg of water. The specific energy required to cause the phase change is 2297 kJ/kg. Assuming th

Answer:

It will take 58 seconds

Step-by-step explanation:

If you have 1 kg of water in the jar, half of it will be 0.5 kg.

To vaporize half of the water (0.500 kg) the energy supply needed is

$2297 kJ/kg*0.5kg=1148.5 kJ$

If the stove is supplying 20 kJ/s, the time its needed is

$\frac{1148.5 kJ}{20\frac{KJ}{s} }=57.425 s$

It will last at least 58 seconds to vaporize half of the water.

Brian is 1 meter 87 centimeters tall. Bonnie is 58 centimeters shorter than Brian. Betina is 26 centimeters taller than Bonnie.

Blizzard [7]

Answer:

Betina is $1\ m\ 55\ cm$ tall

Step-by-step explanation:

let

x ----> Brian's height

y ----> Bonnie's height

z ----> Betina's height

we know that

$1\ m =100\ cm$

$1\ m\ 87\ cm=100\ cm+87\ cm=187\ cm$

$x=187\ cm$

$y=x-58$

substitute the value of x

$y=187-58=129\ cm$

$z=y+26$

substitute the value of y

$z=129+26=155\ cm$

$155\ cm=100\ cm+55\ cm=1\ m\ 55\ cm$

therefore

Betina is $1\ m\ 55\ cm$ tall

A rectangle has sides 2x + 3 and x - 4. what is the perimeter of the rectangle

amid [387]

Write 2x+3(to the power of 2)+x-4(to the power of 2). Then do the equations and you should get 4x+9+2x+16. Combine like terms and that's your answer. I know it might be weird that it's not like 72 or something, but it's math haha. Your answer should be 6x+25! Make sure you understand this before just writing all of this down. Also, don't be afraid to ask your teacher. They are there to help!

the graph of y=|x| is transformed as shown in the graph below , which equation represents the transformed function

statuscvo [17]

Answer:

$y=|\frac{1}{4}x|$

Step-by-step explanation:

Given that

transformed graph of the parent graph y=|x|

The transformed function is shown below:-

We see the graph at y=1 x reaches to 4 i.e, x=4

In the Same manner at y = 1

and x reaches to -4

that is

x=-4

Now, as per the options that are given in the question

The graph would be satisfied these two points would become transformation

$y=|\frac{1}{4}x|$

Now,

At x=4

$y=|\frac{1}{4}x|$

$y=|\frac{1}{4}(4)|$

y = 1

we can say that the point totally satisfied the equation.

So, Option 1 is right that is

$y=|\frac{1}{4}x|$

With the help of a diagram we can go through as attached.
