Answer:

4 and 10

Step-by-step explanation:

To solve this problem, we need to find all the numbers between 1 and 13 that have a sum of 14. The list is shown below:

1 + 13,   2 + 12,   3 + 11,   4 + 10,   5 + 9,   6 + 8,   7 + 7

Now we must figure out which set of numbers include one number that is 2/5 of the value of the other. We can do that by turning the sets of numbers into fractions as shown below:

[tex]\frac{1}{13}\neq \frac{2}{5}[/tex]

[tex]\frac{2}{12}\neq \frac{2}{5}[/tex]

[tex]\frac{3}{11}\neq \frac{2}{5}[/tex]

[tex]\frac{4}{10}= \frac{2}{5}[/tex]    (answer)

[tex]\frac{5}{9}\neq \frac{2}{5}[/tex]

[tex]\frac{6}{8}\neq \frac{2}{5}[/tex]

[tex]\frac{7}{7}\neq \frac{2}{5}[/tex]

The first number is 4, and the second number is 10, and their sum is indeed 14, as given in the problem.

Let's call the first number "x" and the second number "y." According to the information given:

The sum of the two numbers is 14, so we can write the equation:

x + y = 14

The first number (x) is 2/5 of the second number (y), which can be expressed as:

x = (2/5)y

Now, we can solve this system of equations using substitution. First, we'll substitute the expression for x from the second equation into the first equation:

(2/5)y + y = 14

To make the equation easier to solve, we can get rid of the fraction by multiplying both sides of the equation by 5 (the denominator of 2/5):

5(2/5)y + 5y = 5 * 14

This simplifies to:

2y + 5y = 70

Now, combine like terms:

7y = 70

To solve for y, divide both sides by 7:

y = 70 / 7

y = 10

Now that we've found the value of y, we can find the value of x using the second equation:

x = (2/5)y

x = (2/5) * 10

x = 4

So, the two numbers are:

x = 4

y = 10

b = ± 28

Step-by-step explanation:

Given

96² + b² = 100² ( subtract 96² from both sides )

b² = 100² - 96² = 10000 - 9216 = 784 ( take the square root of both sides )

Answer:

P(A and B) = P(A) + P(B) - P(A or B)

                 = 0.6 + 0.45 - 0.66

                 = 0.39

The value of P(A AND B), given the probabilities of P(A), P(B), and P(A OR B),  is found to be 0.39.  

To find the probability of both events A and B occurring, we use the formula for the probability of the union of two events, which is P(A OR B) = P(A) + P(B) \'96 P(A AND B). We rearrange this formula to find P(A AND B) by subtracting P(A) and P(B) from P(A OR B):

P(A AND B) = P(A) + P(B) \'96 P(A OR B)

Substituting the given values:

P(A AND B) = 0.6 + 0.45 \'96 0.66 = 0.39

So, the probability of A and B occurring together, P(A AND B), is 0.39, which rounds to the nearest thousandth as required.

Answer:

114.5 in³

Answer:

Since the range of the original function is limited to y  6, the domain of the inverse function is x ≥ 6.

Step-by-step explanation:

The answer is the statement Since the range of the original function is limited to y > 6, the domain of the inverse function is x ≥ 6.

The domain of the inverse of a relation is the same as the range of the original relation. In other words, the y-values of the relation are the x-values of the inverse.

The positive slope definition tells us that a line with a positive slope is one where the right side of the line is higher than the left side of the line.

So, by the definition given above, we see that

if the range of the original function is limited to y > 6, the domain of the inverse function is x >= 6.

Answer:

i think its 2.7 or 1.7 iriririeieire

Answer:

u = - [tex]\frac{t}{rs}[/tex]

Step-by-step explanation:

Given

t = - rsu ( multiply both sides by - 1 )

- t = rsu ( divide both sides by rs )

- [tex]\frac{t}{rs}[/tex] = u

To find u in terms of r, s, and t given the equation t = -rsu, divide both sides by -rs to get u = -t / (rs).

To solve for u in terms of r, s, and t using the given equation t = -rsu, we need to isolate u. We do this by dividing both sides of the equation by -rs, which gives us u = -t / (rs). This shows that u is inversely proportional to the product of r and s, and directly proportional to -t.

Answer:35%

Step-by-step explanation:

The percentage decrease in the value of the book is 35%.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Cost of the book = £19.80

Selling price of the book = £12.87

The percentage decrease in the value of the book.

= (19.80 - 12.87)/19.80 x 100

= 6.93/19.80 x 100

= 35%

Thus,

The percentage decrease is 35%.

Answer: 25 meters.

Step-by-step explanation:

The missing figure is attached.

Draw a Right triangle as the one shown in the second picture, where "a" is the smallest length of rope  (in meters) that Ryan could buy, which would stretch from one tree to the other tree.

You need to use the Pythagoream Theorem:

[tex]a^2=b^2+c^2[/tex]

Where "a" is the hypotenuse and "b" are "c" are the legs of the Right triangle.

In this case you can identify that:

[tex]b=25-10=15\\\\c=20[/tex]

Knowing those values, you can susbtitute into  [tex]a^2=b^2+c^2[/tex] and then solve  for "a" in order to find its value.

You get:

[tex]a^2=15^2+20^2\\\\a=\sqrt{15^2+20^2}\\\\a=25[/tex]

Answer:

5a) The number of red blocks increases by one every time while the blue one stays the same.

5b) The number of blue blocks increases by one every time while the red one stays the same.

Step-by-step explanation:

I don't really know how to explain this. The best way for you to understand this concept is to google algebraic expressions for pattern rules.

Answer:

a. Alice

b. Briana

c. 0.51 minutes

Step-by-step explanation:

a. Alice formula is valid for any t > 0 minutes, but Briana formula is only valid for

2t - 1 > 0

2t > 1

t > 1/2 minutes

b. They finish when their covered distance is equal to 5 kilometers. For Alice:

t/4 = 5

t = 5*4 = 20 minutes

For Briana:

√(2t - 1) = 5

2t - 1 = 5²

2t = 25 + 1

t = 26/2

t = 13 minutes

c. They are side by side when they have covered the same distance, that is:

t/4 = √(2t - 1)

(t/4)² = 2t - 1

t²/16 = 2t - 1

t² = 16*(2t - 1)

t² = 32t - 16

t² - 32t + 16 = 0

Using quadratic formula:

[tex]t = \frac{-b \pm \sqrt{b^2 - 4(a)(c)}}{2(a)} [/tex]

[tex]t = \frac{32 \pm \sqrt{-32^2 - 4(1)(16)}}{2(1)} [/tex]

[tex]t = \frac{32 \pm 30.98}{2} [/tex]

[tex]t_1 = \frac{32 + 30.98}{2} [/tex]

[tex]t_1 = 31.49 [/tex]

[tex]t_2 = \frac{32 - 30.98}{2} [/tex]

[tex]t_2 = 0.51 [/tex]

Only the second answer has sense for this problem because the race already finished before they spent 31.49 minutes in it.

Answer:

a) Alice starts first, b) Briana gets the finish line first, c) [tex]t \approx 0.509\,min[/tex]

Step-by-step explanation:

a) Alice starts first, since binomial inside the squared root is equal to zero when [tex]t = \frac{1}{2}\,min[/tex], whereas Alice begins at [tex]t = 0\,min[/tex].

b) The instant when each competitor reach finish line is:

Alice

[tex]5\,km = \frac{t}{4}[/tex]

[tex]t = 20\,min[/tex]

Briana

[tex]5\,km = \sqrt{2\cdot t - 1}[/tex]

[tex]25\,km^{2} = 2\cdot t - 1[/tex]

[tex]t = 13\,min[/tex]

Briana gets the finish line first.

c) Alice and Briana are side by side when [tex]a(t) = b(t)[/tex]. Then:

[tex]\frac{t}{4} = \sqrt{2\cdot t - 1}[/tex]

[tex]\frac{t^{2}}{16} = 2\cdot t - 1[/tex]

[tex]t^{2} - 32\cdot t + 16 = 0[/tex]

The roots of the second order polynomial are:

[tex]t_{1} \approx 31.492\,min[/tex] and [tex]t_{2} \approx 0.509\,min[/tex]

Just the second roots makes sense, as they must be side by side at one instant before getting the finish line.

Answer:
