Club B: 100+25x

Answer:

x=40

Step-by-step explanation:

2x+3x-20=180

since they are on the same line, you add them up to 180 to find x

5x-20=180

   +20+20

5x=200

x=40

Answer:

$12

Step-by-step explanation:

Since she has $16 left, this means she spent $84. ($100-$16=$84)

Then, since she bought the same give for 7 of her friends, divide:

84/7=12.

This means that each gift cost $12.

Answer: 803.84 --> 803.8

Step-by-step explanation:

4^4=16x3.14=50.24*16=803.84

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

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:

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.

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:

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]

Henceforth,

Answer:  The acceleration is 0 after 4.5 seconds.

*The distance traveled in the last 15 seconds on the graph is about 225 meters.*

If the question means "distance traveled during the last 15 seconds before coming to a complete stop" The distance is 30 meters.

The attachment shows what I believe to be the missing right side of the graph showing the velocity at 0.

Step-by-step explanation: a.) at 4.5 seconds, the graph is momentarily flat; that is, the derivative, (the change in slope) is 0. There is no change in velocity at that point. Before that, the velocity is increasing, so there is positive acceleration. After that, the velocity is decreasing. So the acceleration is negative.

*The answer choices seem incorrect to me. for part b. Is there a typo?*

b.) From 10 seconds to 25 seconds, the "last 15 seconds" on the graph, the velocity is decreasing at a steady rate; the average velocity is 15m/sec

At  15m/sec × 15 sec, the distance traveled is 225 meters.

If we are to extrapolate to the point there the velocity is 0, assuming the steady rate of deceleration, the motorbike will reach that stopping point at 63.75 seconds. At 15 seconds before that, at 48.5 sec, it is traveling at 4m/sec.

The average velocity during the final 15 seconds is 2m/sec.

2m/sec × 15 sec = 30 meters.

I don't see that choice either, so I wonder if the question is missing something.

If someone else has a better explanation, I hope they they will answer and explain what I missed.

Answer:

I will only be answering B as A has already been correctly Anserd

B is 225

Step-by-step explanation:

You have to draw a trapezium on the graph and work out it's area so

17 + 13 = 30

30÷ 2 = 15

15 × 15 = 225

Answer:

I don't understand your question!!!

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

Step-by-step explanation:

i hope that is right:)

Answer:

W paid $96

B paid $64

Step-by-step explanation:

Let the total amount paid be $x

From the question, we are told that B pays 4/10

That means what W paid will be;

1-4/10 = 6/10

Thus, we have that;

6/10 * x - 4/10 * x = 32

6x/10 -4x/10 = 32

2x/10 = 32

2x = (32 * 10)

2x = 320

x = 320/2

x = $160

6/10 = 6/10 * 160 = $96

4/10 = 4/10 * 160 = $64

Answer:

167.143

Step-by-step explanation:

2:6:7

7 for the perimeter

195/7= 27.875

27.875 * 6 =167.143

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.

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:

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
