Answer:

$9.10 dollars

Step-by-step explanation:

The original price of the shoes is $6.50, so we want to add 40% to that. There are two ways to do this.

Method 1:

Find 40% of 6.50, and add it to 6.50.

[tex]6.5*0.4= 2.6\\6.5+2.6=9.1[/tex]

Method 2:

Multiply 6.5 by 1.4 (including the original percent of 100 and adding 40 percent to it)

[tex]6.5*1.4=9.1[/tex]

Answer:

A) $1440

B) $9440

Step-by-step explanation:

A) 4.5% x $8000 = $360 x 4 years = $1440

B) $1440 + $8000 = $9440

Answer:

40% chance of success

Step-by-step explanation:

The possible integers chosen are 0, 1, 2, 3, and 4.

Since the numbers are randomly chosen and the numbers 2 and 3 represent a success, and the numbers 0, 1, and 4 represent a failure, and there are 5 possible outcomes, there is a 2/5 chance of success. Therefore, you have an estimated 40% chance of a success.

Answer:

Step-by-step explanation:

44) I’ll try to explained detailed as possible.

So first of all we have: 180-120=60 => this is the value of angle(BCA)

=> we know that a triangle has 180 degree in total =>

Now we will have to add all angles,their sum will be equal to 180.

=> (2x+28)+(3x-13)+60=180

2x+28+3x-13=180-60

5x+15=120

5x=105

x=105/5

x=21

=> m(BAC) = 2x+28=29*2+28=58+28=86 degree.

Step-by-step explanation:

Given that:

{(x²+y²)/(x²-y²)} = 17/8

On applying cross multiplication then

since, (a/b) = (c/d) ⇛a(d) = b(c)

Where, x = x²+y², b = x²-y², c = 17 and d = 8

So,

⇛17(x²-y²) = 8(x²+y²)

Multiply the number outside of the brackets with variables in the brackets on both LHS and RHS.

⇛17x²-17y² = 8x²+8y²

⇛17x²-17y² - 8x²-8y² = 0

⇛17x²- 8x² - 17y² - 8y² = 0

⇛9x² - 25y² = 0

⇛9x² = 25y²

⇛9/25 = y²/x²

⇛25/9 = x²/y²

⇛x/y = √(25/9)

⇛x/y = √{(5*5)/(3*3)}

⇛x/y = 5/3

Therefore, x:y = 5:3

Let x = 5a and y = 3a

Now, (x³+y³):(x³-y³)

= {(x³+y³)/(x³-y³)} = [{(x+y)(x²-xy+y²)}/{(x-y)(x²+x-y+y²)}]

= [{(5a)³ + (3a)³}/{(5a)³ - (3a)³}]

= [{(5*5*5*a*a*a) + (3*3*3*a*a*a)}/{(5*5*5*a*a*a) - (3*3*3*a*a*a)}]

= {(125a³ + 27a³)/(125a³ - 27a²)}

= {(152a³)/(98a³)}

= 152/98

Write the obtained fraction in lowest form by cancelling method.

= {(152÷2)/(98÷2)}

= 76/49

Therefore, , (x³+y³):(x³-y³) = 76/49

Answer: Hence, the required value of (x³+y³):(x³-y³) is 76/49.

Please let me know if you have any other questions.

Answer:

  76:49  or  49:76

Step-by-step explanation:

The second relation gives an expression for y in terms of x:

  [tex]\dfrac{x^2+y^2}{x^2-y^2}=\dfrac{17}{8}\\\\8x^2+8y^2=17x^2-17y^2\qquad\text{cross multiply}\\\\25y^2=9x^2\qquad\text{add $(17y^2-8x^2)$}\\\\5y=\pm3x\qquad\text{take the square root}\\\\y=\pm\dfrac{3}{5}x\qquad\text{divide by 5}[/tex]

Substituting into the expression we want the value of, we can factor out x^3 to get ...

  [tex](x^3+y^3):(x^3-y^3)=(1\pm(3/5)^3):(1\mp(3/5)^3)=(125\pm27):(125\mp27)\\\\=152:98\text{ or }98:152=\boxed{76:49\text{ or }49:76}\m[/tex]

Additional comment

There is nothing in the given requirement that means x and y must have the same sign. If the signs are different, then the value of the expression is less than 1, rather than greater than 1.

Answer:Triangle B

Step-by-step explanation:

It is the only one not dilated or rotated, but it was simply moved, which is the definition of translation.

Answer:

B. 10

Step-by-step explanation:

This pair of triangles follows a scale factor. A scale factor is the factor that can get you an exact copy of a triangle, but with bigger or smaller side lengths. In this case, the scale factor is 2 (doing 12/6 on the left side is 2), and dividing that by 20 to get 10. Because we want the smaller triangle, we divide, not multiply. (you could also multiply by 1/2)

Using the together rate, it is found that if Mrs Adams camps alone, she will use all the water in 24 hours.

The together rate is the sum of each separate rate.

In this problem, the rates are:

Hence:

[tex]\frac{1}{12} + \frac{1}{x} = \frac{1}{8}[/tex]

[tex]\frac{x + 12}{12x} = \frac{1}{8}[/tex]

[tex]12x = 8x + 96[/tex]

[tex]4x = 96[/tex]

[tex]x = \frac{96}{4}[/tex]

Answer:

Sue eats 1/3 of the whole pizza

Step-by-step explanation:

Therefore, the probability that Scott chose books A and B is 1/28.

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 means that the event will not occur and 1 means that the event is certain to occur. The probability of an event is calculated by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in many areas of mathematics, science, economics, and everyday life to help make predictions, decisions, and inferences.

Here,

The total number of ways Scott can choose 2 books out of 8 books is given by the combination formula:

C(8,2) = 8! / (2! * 6!) = 28

This means there are 28 possible pairs of books he could choose.

The probability that he chose books A and B is 1 out of 28 because there is only 1 way to choose books A and B out of the 28 possible pairs:

P(A and B) = 1/28
