Answer:

5 dimes and 2 quarters

Step-by-step explanation:

A dime is worth 10 cents. To figure out how many dimes it takes to get to fifty, do:

\(50/10\)

Doing this will give you the answer of 5 dimes.

A quarter is worth 25 cents. To figure out how many dimes it takes to get to fifty, do:

\(50/25\)

Doing this will give you the answer of 2 quarters.

Answer:

1. 5 Dimes

2. 2 Quarters

Step-by-step explanation:

A fifty-cent coin can be written as $0.50. A dime can be written as $0.10. Now you just solve with the simplest math by figuring out how many 0.10's you need to get 0.50. This would be 5

Now a quarter can be written as $0.25. Now you just do the same thing as before. So you would need two $0.25 to get $0.50

The surface areas of the figures are 336, 82 and 836

The figures

For the triangular prism, we have

Surface area = 2 * 1/2 * 6 * 8 + 12 * 10 + 8 * 12 + 6 * 12

Surface area = 336

For the rectangular prism, we have

Surface area = 2 * (7 * 3 + 3 * 2 + 2 * 7)

Surface area = 82

The surface area of the prisms are

1. 336 cm²

2. 82 m²

3. 836 cm²

The area occupied by a three-dimensional object by its outer surface is called the surface area.

A prism is a solid shape that is bound on all its sides by plane faces.

The surface area of prism is expressed as;

SA = 2B +pH

where B is the base area , p is the perimeter and h is the height.

1. SA = 2B +ph

B = 1/2 × 6 × 8

= 24 m²

p = 6+8+10 = 24m

h = 12m

SA = 2 × 24 + 24 × 12

= 48 + 288

= 336 cm²

2. SA = 2( 3× 2) + 3× 7)+ 2 × 7)

= 2( 6+21+14)

= 2( 41)

= 82 m²

3. SA = 2πr( r +h)

The net profit of the company this year is $729,000

Suppose the value of which a thing is expressed in percentage is "a'

Suppose the percent that considered thing is of "a" is b%

Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).

Thus, that thing in number is

\(\dfrac{a}{100} \times b\)

Given;

Last year small manufacturing company netted $540,000

The net profit increased this year by 135%

Now, to find 135% of $540,000

Let the profit this year be x

x*100/$540,000=135

x=135*5400

x=729000

Therefore, net profit by 135% will be $729,000

Answer:

The answer is most likely A.

The reason why, is because since the earning in 6 hours is $94.50, so the hourly wage would be, $15.75 because:

94.50/6 = 15.75

Graph B, for the first hour, the amount of dollars is correct, but in 11 hours, it says 25.75, which is not correct so Graph B cannot be it.

Graph C, shows that at hour 1, that it is 15.75 dollars, but at hour 2 16.75, as well with hour 3, 17.75. The graph is showing an increase of 1 dollar per hour, which is not correct so graph C is not it.

Graph D shows that at hour 6, there is $94.50, which is correct, but at hour 12, its 100.50. This is not true because , the hour has increased by 6, and when it increased by 6, the amount of pay increased by 6 as well, which is not the right way in which you would do so.

The probability that the slope of the line determined by p and the point (5/8, 3/8) is greater than or equal to 1/2 is 5/8.

Let the coordinates of point p be (x,y). Then, the slope of the line determined by p and the point (5/8, 3/8) is:

For the slope to be greater than or equal to 1/2, we must have:

Solving for y, we get:

Graphing this inequality on the unit square, we see that the region satisfying this inequality is a trapezoid with vertices (5/8,3/8), (1,1/2), (1,1), and (3/4,1).

The area of this trapezoid is (1/2)*((5/8 - 3/4) + (1 - 5/8) + (1 - 1/2) + (3/8 - 3/16)) = 5/16.

The area of the unit square is 1, so the probability we seek is 5/16.

Hence, the answer is 5/16 written as a fraction in its simplest form, which is 5/16.

The length of the hypotenuse is 12.52 yards.

Given that a right triangle, we need to find the value of the hypotenuse x,

Trigonometric ratios can be calculated by taking the ratio of any two sides of the right-angled triangle.

We can evaluate the third side using the Pythagoras theorem, given the measure of the other two sides. We can use the abbreviated form of trigonometric ratios to compare the length of any two sides with the angle in the base.

Let us consider a right-angled triangle with one of its acute angles to be x. Then the cosine formula is, cos x = (adjacent side) / (hypotenuse), where "adjacent side" is the side adjacent to the angle x, and "hypotenuse" is the longest side (the side opposite to the right angle) of the triangle.

We know that, the cosine of the angle is the ratio of the base to the hypotenuse,

So,

Cos 37° = 10 / x

x = 10 / Cos 37°

x = 12.52

Hence the length of the hypotenuse is 12.52 yards.

Step-by-step explanation:

By plugging in the values given into \(c * \frac{bc}{4} - (7 - a)\) and using BODMAS rule, the algebraic expression can be evaluated as 47

\(\mathbf{c * \frac{bc}{4} - (7 - a) = 47}\)

Given the algebraic expression, \(c * \frac{bc}{4} - (7 - a)\), to evaluate the expression if a = 4, b = 8, and c = 5, plug in the values into the equation as shown below:

\(5 * \frac{(8)(5)}{4} - (7 - 4)\\\)

\(5 * \frac{40}{4} - (3)\\\\5*10 - 3\)

Applying the BODMAS rule, multiply before you subtract

The state equation for the given system is: x' = Ax + Bu where A = [3 2; 0 2] and B = [1; 0].

To find the state equation of the given system, we first need to rewrite it in the matrix form. Let x1 = x and x2 = z, then we have:

x' = [3 2; 0 2]x + [1; 0]f(t)

z' = [2 3; 1 0]z + [0; 1]f(t)

where x' and z' denote the derivatives of x and z with respect to time, respectively. The matrix A in the state equation * = Ax + Bu is given by:

A = [3 2; 0 2]

This is because the state variables x1 and x2 are multiplied by A in the first equation of the state equation. The input matrix B is given by:

B = [1; 0]

This is because only x1 is affected by the input f(t) in the first equation of the state equation.

Therefore, the state equation for the given system is:

x' = Ax + Bu

where A = [3 2; 0 2] and B = [1; 0].

To calculate the surface area of a rectangular prism, we need to find the area of each of its six faces and then add them up. In this case, the dimensions of the shape are:

Refer to the attachment below.

There are three pairs of faces on a rectangular prism:

8 cm × 3 cm = 24 cm²

Since there are two of these faces, the total area is:

2 × 24 = 48 cm²

8 cm × 6 cm = 48 cm²

Since there are two of these faces, the total area is:

2 × 48 = 96 cm²

3 cm × 6 cm = 18 cm²

Since there are two of these faces, the total area is:

2 × 18 = 36 cm²

Now, add up the areas of all six faces:

Surface Area = 48 + 96 + 36 = 180 cm²

So, the surface area of the rectangular prism is 180 cm².

The functions f and g are:

a. f(x) = 1/x

b. g(x) = x + 2

a) To find two functions f and g such that (fog)(x) = 1/(x + 2), we need to determine how the composition of the two functions f and g produces the given expression.

Let's start by assuming g(x) = x + a, where a is a constant. This means that g(x) adds the constant a to the input x.

Next, let's determine the function f(x) such that (fog)(x) results in the desired expression. We have:

(fog)(x) = f(g(x)) = f(x + a)

b) To simplify the expression 1/(x + 2) and make it match f(g(x)), we can consider f(x) = 1/x.

Substituting the expressions for f(x) and g(x) into (fog)(x), we have:

(fog)(x) = f(g(x)) = f(x + a) = 1/(x + a)

Comparing this with the desired expression 1/(x + 2), we see that a = 2. Therefore, the functions f and g are:

a. f(x) = 1/x

b. g(x) = x + 2

Using these functions, we can verify the composition (fog)(x):

(fog)(x) = f(g(x)) = f(x + 2) = 1/(x + 2)

Thus, (fog)(x) = 1/(x + 2), which matches the desired expression.

Answer:

no letter is repeated: 30 words

letters can be repeated: 36 words

adjacent letters different: 30 words

Step-by-step explanation:

We have a total of 6 letters to create a 2-letter code, so if the letters can't be repeated, the first letter has 6 possible values and the second letter has 5 possible values, so the number of 2-letter code words is:

N = 6*5 = 30 words

If the letters can be repeated, each letter has 6 possible values, then we have:

N = 6*6 = 36 words

If adjacent letters must be different, the two letters in the code must be different, because they are adjacent to each other, so we have:

N = 6*5 = 30 words
