Answer:3

Step-by-step explanation:

The 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.

It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.

The ratio of hats to fedoras = 20:4

Let's suppose Zoe's inventory, should expect to x fedoras

20/4   =  30/x

x = 30/5

x = 6

Thus, the 6 fedoras expect if next 30 hats requested from Zoe's inventory, and She recently provided 20 different hats, including 4 fedoras.

Answer:

7.25cm

Step-by-step explanation:

Let the complete question be;

Jill cuts a piece of cardboard in the shape of a trapezoid. The area of the is 43.5sp cm. If bases are 3.5cm and 8.5cm long, what is the height.

Area of a trapezoid = 1/2(a+b)*h

a and b are the parallel sides (bases)

h is the height

Given

a = 3.5cm

b = 8.5cm

A = 43.5 sq.cm

Required

Height h

Substitute the given values into the expression

Area of a trapezoid = 1/2(a+b)*h

43.5 = 1/2(3.5+8.5)*h

43.5 = 1/2 * 12h

43.5 = 6h

h = 43.5/6

h = 7.25cm

Hence the height is 7.25cm

Respuesta:

Volumen = 0.0010126 m³

Ancho = 7,84 N

Explicación paso a paso:

Dado que:

Masa, m de alcohol = 0,8 kg

Densidad del alcohol, d = 790 kg / m³

Recordar :

Densidad, d = masa, m / volumen, v

Volumen = masa / densidad

Volumen = 0,8 kg / 790 kg / m³

Volumen = 0.0010126 m³

Peso, W = densidad * aceleración debido a la gravedad * volumen

Ancho = 790 * 9,8 * 0,0010126

W = 7.8395

Ancho = 7,84 N

Answer:

95

Step-by-step explanation:

A triangle must always equal 180, so if you take the values of 15 and 70, you get 85.

Then, you take 180 and subtract 85.

This leaves you with 95

Step-by-step explanation:

Answer:

[tex]x + 54\ge 70[/tex]

[tex]x \ge 16[/tex]

Step-by-step explanation:

Given

[tex]Total = 70[/tex] (at least)

[tex]Accumulated = 54[/tex]

Required

Express as an inequality

In inequalities, at least means [tex]\ge[/tex]

So, the expression is:

[tex]x + Accumulated \ge Total[/tex]

Where x represents the additional points

[tex]x + 54\ge 70[/tex]

Solve for x

[tex]x \ge 70 - 54[/tex]

[tex]x \ge 16[/tex]

Hence, she needs at least 16 points

Answer:

x + 90 + 63 = 180

Step-by-step explanation:

∠A + ∠B + 45 + 63 = 180     {Straight line angles}

From the figure we know that , ∠B + 45 = 90

Therefore, ∠A + 90 + 63 = 180

Answer:

Option B is correct.

Step-by-step explanation:

∠A = 27

27 + 90 + 63 = 180

you can see that square right. the square is 90.

Answer:

  y -4 = -1/3(x -9)

Step-by-step explanation:

The point-slope form of the equation for a line is useful for this.

  y -k = m(x -h) . . . . . . . line through point (h, k) with slope m

You are given (h, k) = (9, 4) and m = -1/3. Putting these values into the form gives the equation ...

  y -4 = -1/3(x -9)

Answer: A C E RECTANGLE QUADRILATERAL PARELLELOGRAM

Step-by-step explanation:

Answer:

42gtt/m

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Flow rate in gtt/min = (Total fluid in ml × Drop factor) ÷ (Total hours × 60)

Where, Total fluid in ml = 2,000ml

Drop factor = 15gtt/m

Total hours = 12hours

By putting the following value in the formula, we get

Flow rate in gtt/min = (2,000 × 15) ÷ (12 × 60)

= 30,000 ÷ 720

= 41.67 or 42gtt/m
