lilavasa [31]

Answer:

The answer is c. 8 hours

Step-by-step explanation:

Since her battery dropped 25% in 2 hours then for it to drop 100% would take 8 hours.

25%+25%+25%+25%= 100%

so with this logic

25%= 2 hours

2+2+2+2=8

Hoped this helped !

Cheers, Z

What is the reciprocal of 5/8

V125BC [204]

The reciprocal of 5/8 is 8/5 all you have to do is flip it.
so if you are looking for the reciprocal to 2, then it is 1/2 because of the fraction properties

Instructions: If varies inversely as and =2 when =8, find when =2. Write the equation using the given information, then use the

grigory [225]

Solution:

Given that;

varies inversely as

$\begin{gathered} y\propto x \\ The\text{ expression ecomes the equation below} \\ y=kx \\ Where\text{ k is the constant} \end{gathered}$

=2 when =8,

$\begin{gathered} y=kx \\ 2=k(8) \\ k=\frac{2}{8}=\frac{1}{4} \\ k=\frac{1}{4} \end{gathered}$

The equation becomes

$\begin{gathered} y=kx \\ y=\frac{1}{4}x \end{gathered}$

The value of when =2

$\begin{gathered} y=\frac{1}{4}x \\ y=\frac{1}{4}(2)=\frac{2}{4}=\frac{1}{2} \\ y=\frac{1}{2} \end{gathered}$

Hence, y = 1/2

Question number 41 only . thank you

Answer:

x^2 +y^2

Step-by-step explanation:

Dude this is Pythragorean Theorem =)).

You may have missed this part of your lesson. It's ok and also not ok at the same time beacause pythagorean theorem is a meme.

Ok I'll explain once =)).

Thousands of years ago, a mathematician named Pythagore found out that if we have 3 squares, with one square's area equals to the sum of two other squares, then when we put the sides of the squares together to form a triangle , it'll always be a right triangle ( a triangle with one of its angle is 90°). A square area is measured by the length of its side multipled by itself. So he came up with the statement : In a right triangle, the length of the hypotenuse( the side that does not connect to the right angle) is equalled to the sum of squared other sides.

EG.

In this triangle, the right angle is ^ACB. If length of BC is a, length of AB is c, length of BC is a

I We have a formula :

I \ a^2 + b^2 = c^2

I \

I b \ c

I \

I______\

C a B

So now you can use pythagorean theorem to show off =)).

HOPE YOU LEARN WITH JOY AND HIGH GRADES !!!
