Acellus inverse variation

Answers

Answer 1

Answer:

The current when the resistance is 10 ohms is 24 amps

What are variations?

Variations are simply data that change in values (i.e. not constant)

Types of variation

The types of variations are:

Direct variation
Inverse variation
Joint variation
Combine variation

From the complete question (see attachment), we have the following highlights

The variation is an inverse variation
When current (I) is 30 amps, the resistance (R) is 8 ohms

An inverse variation is represented as:

$k = IR$

Where k represents the constant of variation.

The above equation can be rewritten as:

$I_1R_1 = I_2R_2$

So, we have:

$30 * 8 = I_2R_2$

$240 = I_2R_2$

When the resistance is 10 ohms, we have:

$240 = I_2 * 10$

Divide both sides by 10

$24 = I_2$

Rewrite the above equation as:

$I_2 = 24$

Hence, the current when the resistance is 10 ohms is 24 amps

A bathtub can hold a maximum of 50 gallons of water. Water can be drained out of the tub at a rate of 2 gallons per minute. If the tub is initially completely filled by a faucet at a rate of 1 gallon per minute, how long will it take to drain the full tub if the drain is opened but the faucet is kept on?

Answers

Answer:

50 minutes

Step-by-step explanation:

Given,

Water can be drained out of the tub at a rate of 2 gallons per minute,

So, the drained water in 1 minute = 2 gallon,

That is, change in 1 minute = -2 gallon

( negative sign shows losing water)

Also, it is filled by a faucet at a rate of 1 gallon per minute,

So, the filled water in 1 minute = 1 gallon,

That is, change in 1 minute = + 1 gallon

( Positive sign shows additional water ),

Thus, total change in 1 minute = -2 + 1 = -1 gallon,

Let x be the time after which the bathtub will be emptied completely,

Total change in x minutes = -x gallon,

Bathtub will be emptied, if,

Initial volume of water + total change in water = 0

50 - x = 0 ( given volume of tub is 50 gallon )

$\implies x = 50$

Hence, it will take 50 minutes to drain the full tub.

Need help ASAP plz

Answers

Answer:

Step-by-step explanation:

First, plug in the numbers.

x = -3 and y = 2.

-3(-3) + 4(2) - 5(-3)(2)

Simplify by multiplying.

-3 * -3 = 9

4 * 2 = 8

-5 * -3 * 2 = 30

Your new equation is:

9 + 8 + 30 = ?

Simplify by adding. 9 + 8 + 30 = 47

Answer:

Step-by-step explanation:

-3(-3) + 4(2) - 5(-3)(2)

9 + 8 + 30 = 47

The average of the weights of six people sitting in a boar is 145 pounds. After a seventh person gets into the boat, the average of the weights of all seven people in the boat is 147 pounds. What is the weights ( in pounds ) of the seventh person ?a) 160, b) 159, c) 155, d) 149, e) 147

Answers

Weight :

⇒ x for 6 people
⇒ y for the 7th person

$x/6=145 \n (x+y)/6=147 \n \n x=145*6 \n x=870 \n \n x+y=1029 \n \n 870+y=1029 \n y=1029-870 \n y=159$

The correct answer is B).

x - weight of six people
y - weight of 7th person

$(x)/(6)=145\n (x+y)/(7)=147\n\n x=870\n x+y=1029\n\n 870+y=1029\n y=159\ lb\Rightarrow B$

What is Algebra?

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

Emerson made 408 hand-crafted canine treats to sell at a nearby pet store. She places 24 treats in each pack and sells the sacks for $7 each.

The number of the treats will be given as,

⇒ 408 / 24

⇒ 17

Then the amount of money that she earns will be given as,

⇒ $7 x 17

⇒ $119

The amount of money that Emerson makes if she sells all of the treat bags will be $119.
