Allison goes to the store with $100. She buys the same gift for 7 of her friends. She has $16 dollars left. How much did each gift cost.

Answers

Answer:

$12

This means that each gift cost $12.

El boleto de entrada de una funcion de teatro es de $175.00para nuños y $200para adultos a la funcion entran 470 asistentes recaudandose $88,250.00 ¿Cual es el sistema de ecuaciones para calcular la cantidad de niños y adultosque acudieron a la funcion

Answers

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

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

The rectangular floor of a classroom is 30 feet in length and 38 feet in width. A scale drawing of the floor has a length of 15 inches. What is the perimeter, in inches, of the floor in the scale drawing?

Answers

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

Bonnie deposited $1000 in an investment account on the first of January in 2001. The account pays 7.2% interest compounded annually. How much is the investment worth at the end of 2005? please help, having a mental break down over my math homework <3

Answers

Answer:

About $1415.71

Step-by-step explanation:

We can use the formula for compound interest, given by:

[tex]\displaystyle A=P(1+\frac{r}{n})^{nt}[/tex]

Where P is the initial amount, r is the rate, n is the number of times compounded annually, and t is the time in years.

Our initial amount is the $1000 Bonnie deposited. So, P = 1000.

Our rate is the interest, which is 7.2% of 0.072. So, r = 0.072.

Since it is compounded annually, our n = 1. So, we have:

[tex]A=1000(1+0.072)^t[/tex]

We want the amount after 5 years. So, t = 5. Substitute and evaluate:

[tex]A=1000(1.072)^5\approx\$1415.71[/tex]

The investment will be worth about $1415.71 after 5 years.

A small business makes bottles of lemonade. Today, they have 528 ounces of lemonade to bottle. Each bottle holds 24 ounces of lemonade. They sell each bottle for 2 dollars. How many dollars will the business recive?

Answers

Answer:

$44

Step-by-step explanation:

From the above question:

24oz of Lemonade = 1 bottle

528 oz of Lemonade = m

Cross Multiply

24 × m = 528

m = 528/24

m = 22 bottles

We are told that: they sell each bottle for $2

Hence:

1 bottle = $2

22 bottles = z

Cross Multiply

z = 22 × $2

z = $44

Hence, the amount of dollars that the business will receive = $44

Sameer's father is two years more than three times Sameer's age. Write Sameer father's age if Sameer is x years old at present

Answers

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

Explaination.

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]

Henceforth,

Age of Sameer's father is (3x + 2)

Answer:

Pythagoras Theorem

Step-by-step explanation:

Like you rightly stated, in a right angled triangle. The phenomenon you mentioned is what us called Pythagoras theorem which proved to us that the square of the length of the hypotenuse of a right angled triangle, is equal to the square of the length of the opposite side to the angle in question, and also to the square of the length of the side adjacent to the same angle in question.

Essentially,

a² + b² = c², where c is the hypotenuse and a & b is the length of the two other sides

Answer:

91 meters

Step-by-step explanation:

First find the denominator in the ratio by adding every value up.

[tex]2 + 6 + 7 = 15[/tex]

Now, divide 195 by 15.

[tex]195 \div 15 = 13[/tex]

The longest must be the one with the 7 in the ratio, so we multiply 7 by 13.

[tex]7 \times 13 = 91[/tex]

The longest side is 91 meters long.
