Answer:

x = 12.489996 ft

Step-by-step explanation:

In order to solve one side length of a right triangle given two of other side lengths, you can use the pythagorean theory.

The theory states that the sum of the two adjacent side squares equals the square of the hypotenuse.

Basically:

\(x^2 + y^2 = h^2\)

Since the problem gives you the hypotenuse and one adjacent side length you rearrange the formula as so:

\(x^2 = h^2 - y^2\)

\(x=\sqrt{h^2 - y^2}\)

Then plug in the values:

\(x = \sqrt{16^2 - 10^2} = \sqrt{256-100}=\sqrt{156} = 2\sqrt{39}=12.489996\)

Answer:  

4. 12 (3.5) -15 = 27

5. -18 (445.5) -¾ = 24

Step-by-step explanation:

4. 12? -15 = 27

         12? = 42

             ? = 3.5

5. -18? -¾ = 24

         -18? = 24 + 3/4

          -18? = 96/4 + 3/4

         -18? = 99/4

              ? =  891/2  or 445.5

Thomas can pack the items into a maximum of 20 bags, with each bag containing 24 items after calculated with greatest common divisor.

To find the maximum number of bags Thomas can pack, we need to find the greatest common divisor (GCD) of 120, 168, and 192. The GCD will represent the maximum number of items that can be packed into each bag.

To find the GCD, we can use the Euclidean algorithm. First, we find the GCD of 120 and 168:

168 = 1 * 120 + 48

120 = 2 * 48 + 24

48 = 2 * 24 + 0

Therefore, the GCD of 120 and 168 is 24.

Next, we find the GCD of 24 and 192:192 = 8 * 24 + 0

Therefore, the GCD of 120, 168, and 192 is 24.

So, Thomas can pack 24 items into each bag. To find the maximum number of bags he can get, we divide the total number of items by 24:

Total number of items = 120 + 168 + 192 = 480

Number of bags = 480 / 24 = 20

Therefore, Thomas can get a maximum of 20 bags.

To solve the problem we will calculate the amount of food consumed by Deon's dog in 2.5 weeks.

The new bag of food will last for 2.5 weeks.

Given to us

To know the amount of food consumed by Deon dog in 2.5 weeks, we will multiply the food consumed by Deon dog in 1-week by the Number of weeks for which food is been consumed.

Food consumed by Deon dog in 2.5 weeks

= Food consumed by Deon dog in 1-week x Number of weeks

= 62 cups of dog food x 2.5

= 155 cups of dog food

Thus, the food consumed by Deon's Dog is 155 cups.

As we can see the Dog will consume 155 cups of dog food in 2.5 weeks, therefore, the new bag of food will last for 2.5 weeks.

The exponential function f, whose graph is given below, can be written as f(x)=4.7ˣ.

In mathematics, a function is a rule that maps each element (or input) of a set, called the domain, to a unique element (or output) of another set, called the range. Functions are often represented using function notation, such as f(x), where "f" is the name of the function and "x" is the input variable. The value of f(x) is the output or image of x under the function f.

Here,

If the exponential function f can be written as f(x) = a ⋅ b^x, where a and b are constants, then the graph of f will have the following characteristics:

The y-intercept of the graph will be a, which is the value of f(0).

The base of the exponential function, b, determines the rate of growth or decay of the function. If b > 1, the function grows as x increases. If 0 < b < 1, the function decays as x increases. If b = 1, the function is constant.

The graph of f will be increasing if b > 1 and decreasing if 0 < b < 1. The rate of increase or decrease will be determined by the magnitude of b.

The graph of f will never cross the x-axis, but it will approach the x-axis as x becomes very negative (if b > 1) or very positive (if 0 < b < 1).

Note that the graph of an exponential function can also be characterized by its asymptote, which is a horizontal line that the function approaches but never crosses. The asymptote is the line y = 0 if 0 < b < 1, and the line y = a if b > 1.

Answer:  $3,261.

Step-by-step explanation:

The answer is $3,261.

This means that Jayden's account accumulates more interest than Camden's account over time.

20 boxes of strawberries and 6 boxes of blueberries were purchased by Melissa.

We can use these two equations to solve for x and y:

x + y = 26 (equation 1)

3x + 1.25y = 67.50 (equation 2)

We can multiply equation 1 by 1.25 and subtract it from equation 2 to get rid of y:

3x + 1.25y = 67.50

-1.25x - 1.25y = -32.5

1.75x = 35

x = 20

Substituting x = 20 into equation 1, we get:

20 + y = 26

y = 6

A mathematical definition of an equation is a claim that two expressions are equal and joined by the equals sign "=".

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. As we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

A condition on a variable is what an equation in algebra is. It can only be satisfied if the variable has a specific value. That means that only the value of x = 9 may satisfy the equation 2x - 5 = 13.

From the question:

Let x represent the number of boxes Melissa purchased of strawberries, and y represents the number of boxes Melissa purchased of blueberries.

All in sum, Melissa purchased 26 boxes of berries, thus x + y = 26.

A box of strawberries costs $3, hence the price of x boxes of strawberries is $3.

Blueberries cost $1.25 a box, thus 1.25 dollars are spent on y boxes of blueberries.

In total, Melissa spent $67.50, therefore 3x + 1.25y = 67.50.

x + y = 26 (equation 1)

3x + 1.25y = 67.50 (equation 2)

3x + 1.25y = 67.50

-1.25x - 1.25y = -32.5 (multiplying equation 1 by 1.25 and changing its sign)

1.75x = 35

x = 20

Substituting x = 20 into equation 1, we get:

20 + y = 26

y = 6

Melissa consequently purchased 6 boxes of blueberries and 20 boxes of strawberries.

The simplification of the expression 4a + 3b - a + 3b + 6 is 3(a + 2b + 2)

Simplify 4a + 3b - a + 3b + 6

collect like terms

= 4a - a + 3b + 3b + 6

= 3a + 6b + 6

factorize

= 3(a + 2b + 2)

side a = 3x - 5

side b = 2x - 1

side c = x + 1

Perimeter = 31 cm

The perimeter of a triangle = side a + side b + side c

31 = (3x - 5) + (2x - 1) + (x + 1)

31 = 3x - 5 + 2x - 1 + x + 1

31 = 6x - 5

Add 5 to both sides

31 + 5 = 6x

36 = 6x

divide both sides by 6

x = 36/6

x = 6

Therefore, the value of x from the perimeter of the triangle is 6
