Responder:

Tienda de la ciudad

Explicación paso a paso:

Para obtener el precio unitario por caja:

Importe pagado / número de cajas.

Para cajas de 3 colores:

$ 258/2 = $ 129

Para las cajas de color /:

$ 440/5 = $ 88

$ 88 <$ 129

Por lo tanto, las cajas de colores son más baratas en la tienda de la ciudad.

Answer:

there were 8 adults and 7 students

Step-by-step explanation:

7.25(8) + 5.5(7) = 96.5

the numbers in the parenthesis stand for the number of people

have a great day :D

Step-by-step explanation:

The Answer Is

8 Adults And 7 Students

Answer:

Step-by-step explanation:

So there we have it, <A=135° and <B=45°. This should check when you add them together ("<A and <B are supplementary which means that together their angles equal 180°"). Does 135°+45=180°?     YES!

I Really hope it helps

Answer:

1000 cm^3

Step-by-step explanation:

First, Find the side length of the cube. The surface area is all the area on the surface of a 3-dimensional object. Since a square has 6 congruent faces the formula for surface area is 6s^2 where s is the side length. Since we know the surface area we can solve for the side length.

600=6s^2- DIvide by 6

100=s^2- Take the square root of both sides.

10=s

The volume of a cube is s^3.

10^3=V

1000=V

Answer:

C

Step-by-step explanation:

1. Plot each equation + (4/3,0)

Step-by-step explanation:

let angle be x

Step-by-step explanation:

relationship between perpendicular and hypotenuse is given by sin angle

sin x =p/h

sin x=13/26

x=sin-¹(13/26)=30°

2.relationship between perpendicular and base is given by tan angle

tan x =p/b

tan x =7/16

x=tan -¹(7/16)=23.63°

3.relationship between between perpendicular and base is given by tan angle

tan x =p/b

tanx=31/50

x=tan-¹(31/50)=31.8°

4.relationship between base and hypotenuse is given by cos angle

cos x =b/h

cos x=5/7

x=cos-1(5/7)=44.4°

5.relationship between perpendicular and hypotenuse is given by sin angle

sin x =p/h

sin x=4/14

x=sin-¹(4/14)=16.6

6..relationship between base and hypotenuse is given by cos angle

cos x=6/7

x=cos-¹(6/7)=31.0027

7.relationship between perpendicular and base is given by tan angle

.tanx=29/37

x=tan-¹(29/37)=38.09

8.relationship between perpendicular and hypotenuse is given by sin angle

.sin x=43/60

x=sin-¹(43/60)=45.78

9..relationship between base and hypotenuse is given by cos angle

cos x=32/44

x=cos-¹(32/44)=43.34

Answer:

y=2x+3

Step-by-step explanation:

slope is rise over run. goes up to and over one so your slope is 2/1 or 2.

the c part of the equation of the line is your y-intercept(where the line crosses the y-axis) this is at 3.

so, y=2x+3

Answer:

Similarity doesn't changes angle measures

a) 3x - 16 = 56 ⇒ 3x = 72 ⇒ x = 24°

b) ∠T = x + 46 = 24 + 46 = 70°

c) Scale factor:

Find y using known sides and scale factor:

Answer:

Step-by-step explanation:

Answer:

2 is the slope.

Step-by-step explanation:

To find the slope of this, pick 2 points each

(-2, 3) , (-1,5)

Simply do 5-3 and -1--2.

This equals to 2/1, or 2.

Answer:

x=3, y=-1. (3, -1).

Step-by-step explanation:

6x+y=17

-9x+5y=-32

-----------------

-5(6x+y)=-5(17)

-9x+5y=-32

--------------------

-30x-5y=-85

-9x+5y=-32

-------------------

-39x=-117

39x=117

x=3

6(3)+y=17

18+y=17

y=17-18

y=-1
