Answer:

Bob's dog should be given 216 mg of medicine.

Step-by-step explanation:

Given that:

Weight of dog = 30 lbs

We know that:

1 lb = 0.45 kg

30 lbs = 0.45 * 30 kg

30 lbs = 13.5 kg

Medicine for each kilogram of weight = 16 mg

1 kilogram = 16 mg

13.5 kg = 16 * 13.5 mg

13.5 kg = 216 mg

Hence,

Bob's dog should be given 216 mg of medicine.

Length of the rectangular floor of a classroom = 30 feet

Width of the rectangular floor of a classroom = 38 feet

Length of the floor in a scale drawing = 15 inches

Which means, 1 inch is equal to :

[tex] = \tt\frac{30}{15} [/tex]

[tex] = \tt2 \: feet[/tex]

Thus, 1 inch in the drawing is equivalent to 2 feet of the floor.

Then, width of floor in the scale drawing :

[tex] = \tt\frac{38}{2} [/tex]

[tex] = \tt19 \: inches[/tex]

Thus, the width of the floor in the scale drawing = 19 inches

Perimeter of the floor in the scale drawing :

[tex]= \tt2(length + breadth)[/tex]

[tex] =\tt 2(15 + 19)[/tex]

[tex] =\tt 2(34)[/tex]

[tex] =\color{plum}\tt68 \: inches[/tex]

Thus, perimeter = 68 inches

Therefore, the perimeter of the rectangular floor in the scale drawing = 68 inches

Answer:

P = 2L + 2W

W = 5

P = 2L + 2(5) = 16

2L + 10 = 16

2L = 6

L = 3 ft

Step-by-step explanation:

So we know that the perimeter of a rectangle= 2 (length + width).

We set up the equation so it's 16= 2 (length+ 5)

Divide both sides by 2, so 8 = length + 5.

Subtract 5 from both sides and you get length = 3

Substitute:

4 full teams

1 smaller team.

Answer: there would be 4 full teams, and 3 in the smaller team.

Step-by-step explanation:

You can put 4 into 19 four times, which gets you 16. So the remaining number, 6, is the smaller team.

Answer:

Choice A, C and E

Step-by-step explanation:

Your table is poorly presented

Given

x      y

[tex]\begin{array}{cc} {3} & {1.47} \ \\ {5} & {2.45} \ \\ {9} & {4.41} \ \ \end{array}[/tex]

First, we calculate the constant of proportionality (k)

[tex]k = \frac{y}{x}[/tex]

For (3,1.47)

[tex]k = \frac{1.47}{3}[/tex]

[tex]k = 0.49[/tex]

For (5,2.45)

[tex]k = \frac{2.45}{5}[/tex]

[tex]k = 0.49[/tex]

For (9,4.41)

[tex]k = \frac{4.41}{9}[/tex]

[tex]k = 0.49[/tex]

From the above calculations, the constant of proportionality is 0.49.

So, the usable rows must also have 0.49 as their constant of proportionality

Choice A

[tex](x,y) = (2,0.98)[/tex]

[tex]k = \frac{0.98}{2}[/tex]

[tex]k = 0.49[/tex] --- This is usable

Choice B

[tex](x,y) = (7,4.45)[/tex]

[tex]k = \frac{4.45}{7}[/tex]

[tex]k = 0.64[/tex] --- This is not usable

Choice C

[tex](x,y) = (6,2.94)[/tex]

[tex]k = \frac{2.94}{6}[/tex]

[tex]k = 0.49[/tex] --- This is usable

Choice D

[tex](x,y) = (1,0.54)[/tex]

[tex]k = \frac{0.54}{1}[/tex]

[tex]k = 0.54[/tex] ---- This is not usable

Choice E

[tex](x,y) = (8,3.92)[/tex]

[tex]k = \frac{3.92}{8}[/tex]

[tex]k = 0.49[/tex] --- This is usable

I got this from the internet I don't know why you need brainly when you got the internet or just ask the tutor they have been helping me out SOO MUCH!!

Answer:

3x+2

Step-by-step explanation:

Let Sameer age be x years old at present

Three times Sameer's age = 3 * x = 3x

Two years more than three times Sameer's age = 3x + 2

If Sameer's father is two years more than three times Sameer's age, the the age of Sameer's father at present will be (3x+2) years

So here this question is of concept linear equations. As in linear equations we assumes the unknown number as an variable. Here also we would be doing same.!!

Here we have been provided with a condition that the Sameer's father is two years more than three times Sameer's age.

But we won't be assuming the age of Sameer as any other variable other than x. (Because it's given in the question)

★ Therefore according to the question,

[tex]\implies \: \underline{\boxed{ \sf{Age \: of \: Sameer's \: father \: = \: 3 (Age \: of \: Sameer) \: + \: 2}}} \: \red\bigstar[/tex]

Substituting the age of Sameer as x.

[tex] \longrightarrow \: \sf{Age \: of \: Sameer's \: father \: = \: 3 (x) \: + \: 2} \: \\ \\ \longrightarrow \: \sf{Age \: of \: Sameer's \: father \: = \: 3 \times (x) \: + \: 2} \\ \\ \longrightarrow \: \red{\sf{Age \: of \: Sameer's \: father \: = \: 3x \: + \: 2}}[/tex]

Answer:

x = 3 i promise that's the right answer

Step-by-step explanation:

Answer:

x=3

Step-by-step explanation:

Step #1. Simplify what you've been given

5x-3-2x=18-4x

5x-2x=3x

3x-3=18-4x

Step #2. Add 4x to both sides

3x+4x-3=18

7x-3=18

Step #3. Add 3 to both sides

7x=18+3

7x=21

Step #4. Divide both sides by 7

x=21/7

x=3

Answer:

$2.02

Step-by-step explanation:

1.50/2 = 0.75

0.75 - 0.49 = 0.26

Sandwich = 2(0.75)+1.5 = 3

Drink = (0.49) + 0.49 = 0.98

3 - 0.98 = 2.02

Answer:

El sistema de ecuaciones para calcular la cantidad de niños y adultos que acudieron a la función es:

x+y=270

175x+200y=88,250

Step-by-step explanation:

La información proporcionada indica que a la función entran 470 asistentes entre adultos y niños y con esta información puedes decir que la suma de niños y adultos que entran a la función es igual a 470:

x+y=270, donde

x es el número de niños

y es el número de adultos

Además, se indica que se recaudaron $88,250 y tienes los precios de cada entrada por lo que puedes expresar que la suma de los resultados de multiplicar cada precio por la cantidad de personas que entraron por ese precio es igual a $88,250:

175x+200y=88,250

De acuerdo a esto, la respuesta es que el sistema de ecuaciones para calcular la cantidad de niños y adultos que acudieron a la función es:

x+y=270

175x+200y=88,250

Answer:

[tex]A=45000(0.82)^t[/tex]

Step-by-step explanation:

Given data

P= 45,000

rate= 18%

Recall the expression for the compound interest

[tex]A=P(1+r)^t[/tex]

Since we are talking of depreciation

[tex]A=P(1-r)^t[/tex]

Substitute

[tex]A=45000(1-0.18)^t\\\\A=45000(0.82)^t[/tex]

Hence the exponential function is

[tex]A=45000(0.82)^t[/tex]

Answer:

[tex]8-6i[/tex]

Step-by-step explanation:

Multiply out [tex](3-i)^2[/tex] in order to find out which expression it is equivalent to.

1) Since the whole quantity is squared, write it out as [tex](3-i)(3-i)[/tex].

[tex](3-i)^2\\(3-i)(3-i)[/tex]

2) Multiply binomials by using the FOIL method. Multiply the terms that are listed first in each binomial, then the ones that are listed outermost when looking at both binomials, then innermost, and finally the last terms listed in each binomial. Simplify and combine like terms.

[tex](3-i)(3-i)\\9 - 3i - 3i + i^2[/tex]

[tex]9 - 6i + i^2[/tex]

3)  [tex]i = \sqrt{-1}[/tex], so [tex]i ^2[/tex] must be [tex](\sqrt{-1} )(\sqrt{-1})[/tex]. Thus, [tex]i^2[/tex] is equivalent to -1. Knowing this, simplify and combine like terms.

[tex]9 - 6i + ((-\sqrt{1} )(\sqrt{-1} ))[/tex]

[tex]9 - 6i -1\\8 - 6i[/tex]

Thus, it is equivalent to  [tex]8 - 6i[/tex] .

Answer:

y = -5x - 5

Step-by-step explanation:

to get the coefficient of the 'x' term (which is the slope) you take the difference of the y-values [5 - (-5)] divided by the difference of the x-values  (-2 - 0)

so slope = 10/-2 or -5/1

to get the -5, this is the point at which the line intersects the y-axis; from looking at the graph you can see this is -5
