Answer:

The number of trucks required is 17.

Step-by-step explanation:

28.5 kilograms can be transported in a van. How many trucks are needed to transport 484.5 Kg?

For the transportation of 28.5 kg, one truck is required.

Total mass = 484.5 kg

The number of trucks required is

n = total mass/ mass of one

[tex]n=\frac{484.5}{28.5}\\\\n = 17[/tex]

Answer:

n=-5

Step-by-step explanation:

Answer:

Step-by-step explanation:

8n=-40

n=-40/8

n=-5

Answer:

PK = 75

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal, that is

[tex]\frac{PK}{WK}[/tex] = [tex]\frac{AK}{NK}[/tex] , substitute values

[tex]\frac{PK}{54}[/tex] = [tex]\frac{62.5}{45}[/tex] ( cross- multiply )

45 PK = 3375 ( divide both sides by 45 )

PK = 75

Given:

[tex]a=-\dfrac{3}{4}[/tex]

[tex]b=\dfrac{4}{5}[/tex]

To verify:

[tex]a\div b\neq b\div a[/tex]

Solution:

We have,

[tex]a=-\dfrac{3}{4}[/tex]

[tex]b=\dfrac{4}{5}[/tex]

Now,

[tex]a\div b=\dfrac{a}{b}[/tex]

[tex]a\div b=\dfrac{-\dfrac{3}{4}}{\dfrac{4}{5}}[/tex]

[tex]a\div b=-\dfrac{3}{4}\times \dfrac{5}{4}[/tex]

[tex]a\div b=-\dfrac{15}{16}[/tex]               ...(i)

And,

[tex]b\div a=\dfrac{b}{a}[/tex]

[tex]b\div a=\dfrac{\dfrac{4}{5}}{-\dfrac{3}{4}}[/tex]

[tex]b\div a=\dfrac{4}{5}\times (-\dfrac{4}{3})[/tex]

[tex]b\div a=-\dfrac{16}{15}[/tex]               ...(ii)

From (i) and (ii), it is clear that

[tex]a\div b\neq b\div a[/tex]

Hence verified.

Answer:

-4 19/20

Step-by-step explanation:

2 1/5 ÷ -4/9

Change to an improper fraction

(5*2+1)/5 =11/5

Copy dot flip

11/5 * -9/4

-99/20

Changing back to mixed number

-4 19/20

Answer:

-99/20 or -4.95

Step-by-step explanation:

make the first fraction a simple fraction by multiplying the denominator by the whole number and adding the numerator.

which equals 11/5. Then you multiple by the reciprocal of 4/-9 which is -9/4

to look like 11/5 * -9/4 = -99/20

Answer:

La madre hizo en total 2 y 3/8 litros de jugo.

Step-by-step explanation:

Sabemos que preparó:

3/4 litros de jugo de frutilla = 3/4 L

1 y 1/2 litro de jugo de manzana = (1 + 1/2) L  

1/8 litro de jugo de limón = 1/8 L  

1 y 1/2 litro de agua = (1 + 1/2) L  

¿Cuántos litros de jugo preparó la mamá?

Simplemente debemos sumar los distintos volúmenes de jugo escritos arriba (el de agua no, pues solo nos pregunta cuantos litros de jugo se prepararon)

Total de jugo = 3/4 L +  (1 + 1/2) L  + 1/8 L  

Para completar esta suma, separamos los números enteros de los racionales:

Total de jugo = 1 L + ( 3/4 + 1/2 + 1/8) L

Para resolver la suma dentro del paréntesis, debemos tener todos los números con el mismo denominador.

Recordar que si multiplicamos el numerador y el denominador por el mismo número, entonces el número racional no cambia.

Como el denominador más grande dentro del paréntesis es 8 (que tambien es multiplo de los otros dos), tratemos de reescribir los otros dos números de tal forma que su denominador también sea 8:

Total de jugo = 1 L + ( (2/2)*(3/4) +(4/4)*(1/2) + 1/8) L

                       = 1 L + (6/8 + 4/8 + 1/8) L

                       = 1 L + (11/8) L

podemos reescribir el segundo termino como:  

                        = 1L + (8 + 3)/8 L

                        = 1L + (8/8) L + (3/8) L

                         = 1L + 1L + 3/8 L

                          = 2L + 3/8 L

La madre hizo en total 2 y 3/8 litros de jugo.

In a pair of similar triangles, the corresponding sides are proportional. ... When the sides are corresponding it means to go from one triangle to another you can multiply each side by the same number. In the diagram of similar triangles the corresponding sides are the same color.

Answer:

aₙ = 1 + 1(n - 1)

Step-by-step explanation:

This is an arithmetic sequence, which will use the equation:

aₙ = a₁ + r(n - 1)

Therefore the expression for the nth term would be:

aₙ = 1 + 1(n - 1)

Diagonal Length = v(92.4² + 50²)

V(8537.76 + 2500)

V(1037:76)

Diagonal Length 105

Answer:

92.3ft

Step-by-step explanation:

Let the con=rners be A,B,C and d

so AC=105 ft and AB=50ft

using Pythagoras theroem: h^2=b^+p^2

105^2=50^2 + p^2

P^2= 11025-2500

p= √8525

p=92.33

Answer:

154 girls.

Step-by-step explanation:

If ratio of girls to boys is 3 : 4 then 3 / (3+4)  = 3/7 of the total is girls.

Number of girls = 3/7 * 360

= 154.

Answer:

(a) Equations for both

[tex]y = 500 + 12x[/tex] --- lifeguard

[tex]y = 15x[/tex] --- camp counselor

(b) Total pay for 5 days

Lifeguard pays $800

Camp counselor pays $375

(c) Which pays more

Lifeguard job pays more

Step-by-step explanation:

Let

[tex]x \to hours[/tex]

[tex]y \to total\ pay[/tex]

Given

Lifeguard job

[tex]Signing\ bonus = \$500[/tex]

[tex]Rate = \$12/hr[/tex]

Camp counselor job

[tex]Signing\ bonus =\$0[/tex]

[tex]Rate = \$15/hr[/tex]

Solving (a): The equation for both

The total pay for each job is calculated as:

Total Pay = Signing Bonus + Rate * Hours

So, we have:

Lifeguard

[tex]y = 500 + 12*x[/tex]

[tex]y = 500 + 12x[/tex]

Camp counselor

[tex]y = 0 + 15 * x[/tex]

[tex]y = 15x[/tex]

Solving (b): Total pay for 5 days

First, we calculate the total hours worked in 5 days

[tex]x = 5hrs/day * 5days[/tex]

[tex]x = 25hrs[/tex]

So, the pay for each is:

[tex]y = 500 + 12x[/tex]

[tex]y =500 + 12*25[/tex]

[tex]y =800[/tex] --- Lifeguard

[tex]y = 15x[/tex]

[tex]y = 15 * 25[/tex]

[tex]y = 375[/tex] --- camp counselor

Solving (c): Which job pays more

By comparing the solution in (b)

[tex]800 > 375[/tex]

Hence, lifeguard job pays more

Answer:

x° = 64°

Explaination:

This is a right angled triangle so one of the angle is 90°.

So, x° + 90° = 154° (Exterior angle property)

x° = 154° - 90° = 64°

Therefore x° = 64°

Answer:

The slope of a launch ramp cannot be too high or too low.

The length of a landing ramp must be long enough for riders to recover from the jump, but short enough so they do not lose speed for the next jump.

The slope of a ramp is found by dividing the height of the ramp by the length of the ramp.
