Answer:

Assuming the 19 stood for an exponent, q = 1.098...

Step-by-step explanation:

Plugging in [tex]q^{19} = q + 4[/tex] in the graphical calculator, we can see that the solution is approximately q=1.098. There are no ways of solving this equation algebraically.

Answer:

q = 15

Step-by-step explanation:

19 = q + 4

Subtract 4 from each side

19-4 = q + 4-4

15 = q

Charlie travelled greater amount of time.

An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

Given:

D(t) = 60 |t- 3|

for, t=0

D(0) = 60*3 = 180

For t=1,

D(1) = 120

For t= 2

D(2) = 60

According to the data of Charlie and Annabeth it can bee seen that charlie had been travelling greater amount of time.

Answer:

[tex]Ratio = 9 :80[/tex]

Step-by-step explanation:

Given

[tex]A_1 = 18ft^2[/tex] --- Area of smaller rectangle

[tex]A_2 = 160ft^2[/tex] --- Area of bigger rectangle

Required

Determine the area of the areas.

The ratio is calculated by the dividing the areas of rectangles.

[tex]Ratio = \frac{A_1}{A_2}[/tex]

Substitute values for A2 and A1

[tex]Ratio = \frac{18ft^2}{160ft^2}[/tex]

[tex]Ratio = \frac{18}{160}[/tex]

Simplify the fraction

[tex]Ratio = \frac{9}{80}[/tex]

Represent as ratio

[tex]Ratio = 9 :80[/tex]

Hence, the ratio of the rectangles is 1 to 9

Answer:

50(1.25p) and 50(0.25p + 1.00)

Step-by-step explanation:

They both equal the same answer.

50(1.25p) = 62.5

50(0.25p + 1.00) = 62.5

when in parentheses, you multiply

50 * 1.25 = 62.5

50 * 0.25 + 1.00 = 62.5

The expression for the given scenario is 50(0.25p+1.00). Therefore, option A and C are the correct answers.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, Mr. Hamilton sponsors the creative writing club.

He went to a local printing shop that charges $0.25 per page in the book and $1.00 to bind the pages together.

The booklet Mr. Hamilton is making has p pages, and he plans to make 50 booklets.

So, the expression is 50(0.25p+1.00)

= 12.50p+50.0

Therefore, option A and C are the correct answers.

Answer:

The cost of 1 kg is AED1.49

Step-by-step explanation:

Given

[tex]Cost = AED7.75[/tex]

[tex]Weight = 5.2kg[/tex]

Required

Determine the cost of 1 kg grape

To do this, we simply divide the cost of 5.2kg by 5.2kg.

i.e.

[tex]Unit\ Cost = \frac{AED7.75}{5.2kg}[/tex]

[tex]Unit\ Cost = AED1.49/kg[/tex] -- approximated

So, the cost of 1 kg is AED1.49

Answer: x = 2,340 homes without children

There are 2,340 homes without children.

Step-by-step explanation:

'x' represent the number of homes without children

'y' represent the number of homes with children

x : y = 9 : 7

Since the total number of homes is 4160 means x + y = 4160.

From x + y = 4160 follows y = 4160 - x.

Plug y = 4160 - x into x : y = 9 : 7

x : (4160 - x) = 9 : 7
