Si mi mamá compra un refrigerador del costo de $11,780 y con el descuento del 25% cuanto pagara en total mi mamá

Answers

Answer:

Precio a pagar= $8,835

Step-by-step explanation:

Costo de lista del refigerador= $11,780

Porcentaje de descuento= 25% = 0.25

Para calcular el precio que va a pagar con el descuento aplicado, tenemos que usar la siguiente formula:

Precio a pagar= costo de lista*(1- porcentaje de descuento)

Precio a pagar= 11,780*(1 - 0.25)

Precio a pagar= 11,780*0.75

Precio a pagar= $8,835

The diagram shows two right-angled triangles. OAB
and OCD
Work out the length of BD. I
7 cm
4 cm
14 cm

Answers

Given:

The diagram shows two right-angled triangles OAB  and OCD.

To find:

The length of BD.

Solution:

Let the length of BD is x.

In triangle OAB and OCD,

[tex]\angle AOB\cong \angle COD[/tex]           (Common angle)

[tex]\angle ABO\cong \angle CDO[/tex]           (Right angle)

[tex]\Delta OAB\sim OCD[/tex]                           (By AA property of similarity)

We know that, the corresponding sides of similar triangles are proportional. So,

[tex]\dfrac{AB}{CD}=\dfrac{OB}{OD}[/tex]

[tex]\dfrac{4}{7}=\dfrac{14}{14+x}[/tex]

[tex]4(14+x)=14(7)[/tex]

[tex]56+4x=98[/tex]

Subtracting 56 from both sides, we get

[tex]4x=98-56[/tex]

[tex]4x=42[/tex]

[tex]x=\dfrac{42}{4}[/tex]

[tex]x=10.5[/tex]

Therefore, the length of BD is 10.5 cm.

The simplification of expression [tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]  is  [tex]x^{5}y^{2}[/tex].

SimplificationWhat is simplification?

Finding a solution to a complicated calculation that may involve square roots, cube roots, plus and minus integers, division, multiplication, and other mathematical operations is typically referred to as simplification.

What is exponent?

The number of times a number has been multiplied by itself is referred to as an exponent.

Rule of exponents:

Rule of the product of powers: When multiplying like bases, add the powers together.

Rule of the quotient of powers: When splitting like bases, take the powers out.

Solution for the expression:

The expression is given as

[tex]\frac{x^{6}y^{4} }{xy^{2} }[/tex]

Applying multiplication and product rule, one power of x will be reduced and 2 power of y will be reduced.

Thus, the the simplified equation will become [tex]x^{5}y^{2}[/tex].

use the graph above. find the slope and the y-int, then give the equation of the line y=mx+b

Answers

Answer: y = 2x + 4

Step-by-step explanation:

By looking at the graph, we can use rise over run to figure out the slope:

[tex]\frac{rise}{run} = \frac{2}{1} = 2[/tex]

Next, to find the y-intercept, see the point where the line meets with the y-axis, which is at (0,4). Now, simply place those variables found into y=mx+b, where m is the slop and b is the y-intercept.

y = mx + b

y = 2x + 4

Jane and her neighbor Amil are jealous of each other’s gardens. Amil’s garden is twice the size of Jane’s garden. Janes garden has 22 watermelons and Amil’s garden has 28. Whose garden has the greatest density of watermelons Support your answer with math?

Answers

Answer:

Jane has the greatest desity of watermelons.

Step-by-step explanation:

25ft2/22= 1.13          100ft2/28= 3.57

For example, if Jane’s garden is 25 square feet then that means there would be about 1 watermelon per square foot. If Amil’s garden is twice the size of Jane’s at 100 square feet, then you could fit about 3 watermelons per square foot. This means that Jane has the greatest density of watermelons because Amil can fit more watermelons per square foot.
