neonofarm [45]2 years ago

Answer:

x = A/7

Step-by-step explanation:

Given that the screen is rectangular, recall that the area A of a rectangle whose length is L and width is W is given as

A = L * W

Hence if the width is 7 inches and the length is x inches then the area which is A square inches is connected to both sides as

A = x * 7

Divide both sides by 7

x = A/7 inches

Answer:

x can be 3, -3, i, or -i.

Step-by-step explanation:

If you can't find the factoring by looking at this, simplify the equation.

let  

x

2

=

y

to make things easier to see

Now we have  

y

2

−

8

y

−

9

=

0

See it now?

We can factor into  

(

y

−

9

)

(

y

+

1

)

Now substitute back in  

x

2

for  

y

.

(

x

2

−

9

)

(

x

2

+

1

)

Since  

(

x

2

−

9

)

is a difference of two squares,

(

x

−

3

)

(

x

+

3

)

Now we have  

(

x

−

3

)

(

x

+

3

)

(

x

2

+

1

)

x can be 3, -3 for the first two parts

x

2

+

1

=

0

can become  

x

2

=

−

1

Taking the positive and negative root means  

x

=

±

√

−

1

Thus  

x

=

±

i

in addition to 3 and -3.

If a car factory checks 320 cars and 12 of them have defects, how many out of 560 will have defects? Use proportions
Shkiper50 [21]

Answer:

  • Total number of cars having no defection = 539
  • Total number of cars out of 560 will have defects = 560 - 539 = 21

Step-by-step explanation:

As

  • A car factory checks 320 cars, and
  • 12 of them have defects.

Total number of cars = 560

The number of cars defected out of the cars that have

been checked = 320 - 12 = 308

The equation of the scenario will be:

\left[560\:\times \:308\right]\:\div \:320    ⇒    \frac{172480}{320}=539

so

  • Total number of cars having no defection = 539
  • Total number of cars out of 560 will have defects = 560 - 539 = 21

A bag contains Red, Green or Yellow balls. A ball is taken at random from the bag. The probability that it is Red is 0.4 and the
Luba_88 [7]

Answer:

1000 balls

(there are infinitely many solutions to this question; you can scale up 1000, use a different total, etc.)

Step-by-step explanation:

there are, of course, multiple possible numbers,

but the easiest way is to go with 1000, because we can say 375 / 1000 and 400 / 1000

(0.4 + 0.275 + 0.225 = 1)

400 out of 1000 balls are red (400/1000 = 4/10 = 0.4)

375 out of 1000 balls are green (375/1000 = 3.75/10 = 0.375)

225 out of 1000 balls are yellow (225/1000 = 2.25/10 = 0.225)

the question never gave detail as to if the answer should be the <em>lowest</em><em> </em>number of possible balls, so this value is possible.

So, a possible number of balls in this bag is 1000.
