Answer:

357 passengers

Step-by-step explanation:

[tex]\frac{x}{420}=\frac{85}{100}[/tex] (The [tex]\frac{85}{100}[/tex] is 85% of the 100% people because 15% is missing)

When you cross-simplify you get: [tex]\frac{x}{21}=\frac{85}{5}[/tex] which is [tex]\frac{x}{21}=17[/tex]

Finally, multiply 17 by 21 to get x.

Therefore, x=357

50 divided by 4 is 12.5, so it is 12.5 for 1 soap cake, 12.5 x 36 is 45.0

The answer is 45.0

Answer:  The width is 7 meters. The length is 10 meters.

Step-by-step explanation:   Area = Length × width

Length is 2w - 4  

Substitute that value for length, then solve for w.

70 = w(2w - 4)

70 = 2w² - 4w  reorganize to quadratic equation form

2w² - 4w -70 = 0   These are All even numbers; factor out 2 (divide all by 2)

w² - 2w - 35 = 0  factor this

(w - 7)(w + 5)    set each factor = 0 and calculate the value of w.

w+5=0  w= -5  (disregard this one because dimensions of real rectangles can't be negative)

w - 7 = 0  w = 7   The width is 7

Substitute into the original expressions to get the value of Length.

2(7) -4 = L    14 - 4 = L  The Length is 10.

Check by substituting into the original equation:

w × 2w -4 = 70

7 × 2(7) -4 = 70

7 × 10 = 70    TRUE!

w

Dimensions of the rectangle are length=10 meter and width= 7 meter

A rectangle is a quadrilateral with four right angles.

Given,

The length of a rectangle is 4 meter less than twice its width

Consider,

l is the length of the rectangle

w is the width of the rectangle

l=2w-4

Area of the rectangle = Length × Width

70=l × w

Substitute the value of l is the second equation

70=(2w-4)×w

[tex]2w^{2} -4w=70\\2w^{2} -4w-70=0[/tex]

Take 2 outside

[tex]2(w^{2}-2w-35)=0\\ w^{2} -2w-35=0\\(w+5)(w-7)=0[/tex]

w=7,-5

Hence w wont be negative value

Therefore w=7 meter

Then,

l×w=70

[tex]l=\frac{70}{7}\\[/tex]

l=10 meter

Hence, the dimensions of the rectangle are length=10 meter and width= 7 meter

Answer:

A) [tex]m=8.65h[/tex]

B) $29.58

Step-by-step explanation:

Earnings per hour = $8.65

To find:

A) Write a rule for money m as a function of the number of hours h spent mowing lawns.

Earnings done in one hour = $8.65

Number of hours = [tex]h[/tex]

To find the total earnings, [tex]m[/tex] as a function of number of hours [tex]h[/tex], we need to multiply per hour earnings with number of hours [tex]h[/tex].

Therefore, the equation is:

[tex]m=8.65h[/tex]

B) How much does Robert earn if she works 3 hours and 25 minutes?

First of all, let us convert 3 hours and 25 minutes to hours.

3 hours 25 minutes = 3.42 hours

Therefore, total earnings are:

[tex]m = 8.65\times 3.42 = \$29.58[/tex]

Answer:

Step-by-step explanation:

Goven the length of the field = 110m

Width = 80m

The length of the diagonal is expressed using the pythagoras theorem;

d² = l² + w²

d² = 110² + 80²

d² = 12100 + 6400

d² = 18500

d = √18500

d = 136.01

Hence the players have to run 136.01m diagonally

Explicação passo a passo:

Dado que:

Principal = 4000

Juros = 586

Taxa (r) = 29,3% ao ano = 0,293

Juros simples = principal * taxa * tempo

586 = 4000 * 0,293 * t

586 = 1172t

t = 586/1172

t = 0,5 anos

Tempo = (0,5 * 12) = 6 meses

B.)

principal = $ 90909,09

Montante final = 100.000

Taxa (r) = 12% = 0,12

Usando a fórmula:

Quantidade final = p (1 + rt)

Taxa = r; t = tempo

100000 = 90909,09 (1 + 0,12t)

100000 = 90909,09 + 10909,0908t

100000 - 90909,09 = 10909,0908t

9090,91 = 10909,0908t

t = 9090,91 / 10909,0908

t = 0,8333334

Número de meses:

0,8333334 * 12

= 10 meses
