Step-by-step explanation:
A rectangle has an area of 18 square feet. A similar rectangle 1
has an area of 160 square feet. What is the ratio of the areas of these
similar rectangles?
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
solve for q 19 = q + 4 q=
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
Jesse bought 5.2 kilograms of grapes for AED 7.75. How much would 1 kilogram of grapes cos
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

A solution consisting of 95 mg of dopamine in 95 mL of solution is administered at a rate of 30 ml/hr. Complete parts (a) and (b) below.
a. What is the flow rate in mg of dopamine per hour?
mg/hr (Type an integer or decimal rounded to the nearest thousandth as needed.)
Answer:
30 mg
Step-by-step explanation:
Flow rate of dopamine per hour:
Flow rate of dopamine per hour = (95g)*(30ml/hr) / 95ml
Flow rate of dopamine per hour = 30mg

Por lo tanto, es de dimensión cero, es decir, adimensional. Contiene el significado de lugar, de existencia, pero no tiene elementos mensurables, es decir, no se puede medir.
En contextos geométricos, una línea es un cuerpo unidimensional de forma y longitud arbitrarias. Todos los objetos unidimensionales, como cuerdas, líneas rectas, mitades y perímetros, son líneas. Se cree que una línea se forma cuando un punto de dimensión cero se mueve en el espacio y forma una línea infinita de múltiples puntos.
Intuitivamente, el concepto de plano se puede describir como una superficie perfectamente recta (es decir, sin curvatura ni cavidad) y lisa, que tiene volumen cero y ocupa solo las dos dimensiones del espacio tridimensional.
La superficie de un objeto se refiere a una superficie bidimensional, que separa el objeto de otros objetos y del entorno. En topología, la superficie es una dimensión bidimensional.

Kate has some dimes and quarters. If she has 23 coins worth a total of $3.50, how many of each type of coin does she have?
23=d+q, d=23-q
350=10d+25q, using d from above
350=10(23-q)+25q
350=230-10q+25q
120=15q
q=120/15
q=8, and since d=23-q
d=23-8=15
So there are 15 dimes and 8 quarters

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.
Pick all the expressions that represent how much Mr. Hamilton will spend making the
booklets.
12.50p + 50.00
50(1.25p)
50(0.25p + 1.00)
12.50p + 50.00p
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.
