Como pasar una potencia de negativa a positiva ?

Answers

Answer 1

Answer:

Cuando tenemos un exponente negativo hay que INVERTIR LA BASE para pasar a exponente positivo. Fíjate que el poner el inverso de la base no significa cambiar el signo de la misma. Al final el signo del resultado dependerá de si el exponente es par o impar. Con las fracciones ocurre lo mismo.

Answers

Answer:

38+31+43+x=180

Step 1: Simplify both sides of the equation.

38+31+43+x=180

(x)+(38+31+43)=180(Combine Like Terms)

x+112=180

Step 2: Subtract 112 from both sides.

x+112−112=180−112

At Middle school ,60% of the 800 students participate in music. How many students participate in music.???

Answers

It would be 480, because I did it in Desmos

Answer:

480

Step-by-step explanation:

800=100% value

x-60%

800/x = 100%/60%

now solve for x

(800/x)*x=(100/60)*x      ( multiply both sides of the equation by x )

800=1.66666666667*x     ( then we divide both sides of the equation by 1.66666666667 to get x )

480 = x

x= 480

so 60% of 800 is 480

Answer:

Step-by-step explanation:

Let ABC be the smallest triangle where

AB = 2cm ; BC = 4cm ; AC = 3cm

ABC = h° ; ACB = g° ; BAC = i °

Let XYZ be the largest triangle where

XY = 4cm ; YZ = 8cm ; XZ = 6cm

XYZ = f ° ; YZX = e°

It's given that ABC & XYZ are similar . So ,

[tex] \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} [/tex]

=> (AB & XY) ; (BC & YZ) ; (AC & XZ) are corresponding sides.

=> (ABC & XYZ) ; (ACB & YZX) ; (BAC & YXZ) are corresponding angles.

Hence,

One year, a certain city experienced a
low temperature of -15°F and a high
temperature of 110°F. What is the
difference in temperature from the
lowest to the highest?
[?] F

Answers

Answer:

Step-by-step explanation:

there is a 125 degree difference between the two

The difference in temperature from the lowest to the highest is 125°F.

Given that, one year, a certain city experienced a low temperature of -15°F and a high temperature of 110°F.

To find the difference in temperature from the lowest to the highest, we need to subtract the low temperature from the high temperature.

The difference will be in Fahrenheit (F):

Difference = High temperature - Low temperature

Difference = 110°F - (-15°F)

Difference = 110°F + 15°F

Difference = 125°F

So, the difference in temperature from the lowest to the highest is 125°F.

Primo car rental agency charges $50 per day plus $0.30 per mile. Ultimo car rental agency charges $20 per day plus $0.70 per mile. Find the daily mileage for
which the Ultimo charge is twice the Primo charge.
What is the mileage?

Answers

Answer:

cdcdc

Step-by-step explanation:

Answer:

Let's assume m represents the mileage of the car.

Given that, Primo car rental agency charges $33 per day plus $0.20 per mile.

So, the total charge for this agency = 33 + 0.20m.

Similarly total charge of the ultimo car = 17 + 0.85m.

Now we need to find the daily mileage for which the ultimo charge is four times the primo charge. So, we can set up an equation as follows:

17 + 0.85m = 4 *( 33 + 0.20m )

17 + 0.85m = 132 + 0.80m By distribution property.

17 + 0.85m -0.80m = 132 + 0.80m -0.80m Subtract 0.80m from each sides.

17 + 0.05m = 132

17 + 0.05m - 17 = 132 - 17 Subtract 17 from each sides.

0.05m = 115

Divide each by 0.05.

So, m = 2300

Hence, the daily mileage is 2300 miles.

Well, 5 to 11 is just saying 5:11 just in a different way. This (:) means (to)  also. So how you get the roof to a 33 foot run is to change the 5 into a 3 and the you leave the 11 alone and then you 33 -foot run.

Louise has a television in her family room that is 3 feet wide and 5 feet long. She has a television that is similar in shape in her bedroom that is 1.5 feet long. What is the perimeter of the television in Louise's bedroom?

Answers

Answer:

The perimeter of the TV = 8 feet

Step-by-step explanation:

The keywords in this question are "similar in shape". This means that the dimensions of the two TVs are equivalent, but they are not the same.

TV in family room = 3 feet wide, 5 feet long = 3/5

TV in bedroom = 1.5 feet wide, x feet long = 1.5/x

Since the TVs are similar:

[tex]\frac{3}{5} = \frac{1.5}{x} \\cross-multiplying:\\3 \times x = 5 \times 1.5\\3x = 7.5\\x = \frac{7.5}{3} \\x = 2.5\ feet[/tex]

Therefore the TV in bedroom is 1.5 feet long and 2.5 feet wide.

Perimeter of a TV = perimeter of a rectangle

Perimeter of a rectangle = (2 × Length) + (2 × width)

Perimeter = ( 2 × 1.5) + ( 2 × 2.5)

= 3 + 5 = 8 feet
