Answer:

${x}^{5} + 5 {x}^{4} y + 10 {x}^{3} {y}^{2} + 10 {x}^{2} {y}^{3} + 5x {y}^{4} + {y}^{5}$

Hello!

First you have to find angle 1

angle 1 and angle 4 are supplementary meaning they add to 180

angle 1 + angle 4 = 180

angle 1 + 150 = 180

angle 1 = 30

The angles in a triangle always add up to 180

angle 1 + angle 2 + angle 3 = 180

30 + 40 + angle 3 = 180

70 + angle 3 = 180

angle 3 = 110

The answer is 110°

Hope this helps!

What is the area of rectangle ABCD with vertices A -3,0 B 3,2 C 4,-1 D -2,-3

Naddik [55]

For this, simply find the width and length by finding the distance between the two points. This can be done using the equation $\sqrt{(y2 - y1)^2 + (x2 - x1)^2}$

AB(length): $\sqrt{(0 - 2)^2 + (3 - (-3))^2}$

--> $\sqrt{-2^2 + 6^2}$

---> $\sqrt{40}$ = 6.32

BC(width): $\sqrt{(2 - (-1))^2 + (4 - 3)^2$

--> $\sqrt{(2 + 1)^2 + 1^2}$

---> $\sqrt{27 + 1}$

----> $\sqrt{28}$ = 5.29 ≈ 5.3

Area = 33.496 ≈ 33.5

Last year, Nicholas started babysitting to earn extra spending money. Over the summer, he tracked how much money he earned at ea

Ierofanga [76]

Answer:

25%

Step-by-step explanation:

The 5 values of the given box plot are;

The minimum value = 20

The first quartile, the 25th percentile point, Q₁ = 25

The median or second quartile, the 50th percentile point, Q₂ = 30

The third quartile, the 75th percentile point, Q₃ = 40

The maximum value = 55

The range = The maximum value - The minimum value

∴ The range = 55 - 20 = 35

We note that Nicholas earned $25 or less from the minimum value up to first quartile, Q₁, which is the 25th percentile point, where we have 25 percent of the data points

Therefore, the percent of the time Nicholas earned $25 or less is 25 percent of the time.

estaba previsto destinar 3/14 de partes de una finca a plazas de aparcamiento pero finalmente han destinado 3/4 de lo previsto a

JulsSmile [24]

Queremos ver que fracción de la finca se ha destinado a plazas de aparcamiento.

La solución es:

La fracción de la finca que se destina a plaas de aparcamiento es 3/56

Sabemos que originalmente se iba a destinar 3/14 del total de la finca a plazas de aparcamiento, pero finalmente se destino 3/4 de lo previsto a zonas ajardinadas.

Es decir, se destino 3/4 de los 3/14 del total de la finca a zonas ajardinadas, entonces el 1/4 restante se dedico a plazas de aparcamiento, esto da:

(1/4)*3/14 = 3/56

La fracción de la finca que se destina a plaas de aparcamiento es 3/56
