a regulat pentagon has side lenghts of 5.8cm and apothem of 4cm. calculate its perimeter and area​

Answer:

58 students were in each bus

Step-by-step explanation:

First, you'd have to subtract 29 from 551. This gives you 522. Then, you'd simply have to divide 522 by 9. 5 cannot go into 9 so we drag down the 2, 9 can go into 52 5 times. Then, you'll be left with 7, so you bring down the last digit, 2. 9 goes into 72 exactly 8 times.

To circle all values with a z-score greater than 0.5, calculate the z-score for each value and compare it to 0.5. The values with a z-score greater than 0.5 are 76 and 78.

To determine which values have a z-score greater than 0.5, we need to calculate the z-score for each value in the data set. The z-score formula is calculated by subtracting the mean from a value and then dividing by the standard deviation. If the resulting z-score is greater than 0.5, we circle the corresponding value.

Based on the calculations, the values with a z-score greater than 0.5 are 76 and 78. Therefore, these two values should be circled.

Answer:

2 and a half

Step-by-step explanation:

To solve this, divide the total amount of free time [5/6] by the time it takes to play one video game [1/3]

Remember that dividing 5/6 by 1/3 is the same as multiplying 5/6 by 3/1.

Multiply the numerators

5 x 3 = 15

Multiply the denominators

6 x 1

15/6 = 2 3/6

So, Lamar can play 2 and a half video games

I hope this helps!

The answer is 2 and a half.

Answer:

your answer would be 9 printers

The answer is:

There are a total of 9 black and white printers

To solve the problem, first, we need to calculate how many color printers represents two-fifths of the total printers, then, calculate the number of black and white printers using the total number of printers and the number of color printers.

Calculating how many color printers does the departament have:

[tex]ColorPrinters=TotalPrinters*\frac{2}{5} \\\\ColorPrinters=15*\frac{2}{5}\\\\ColorPrinters=\frac{30}{5}=6[/tex]

Therefore, we have that there are 6 color printers.

Now, calculating the number of black and white printers, we have:

[tex]TotalPrinters=ColorPrinters+BlackAndWhitePrinters\\\\BlackAndWhitePrinters=TotalPrinters-ColorPrinters\\\\BlackAndWhitePrinters=15printers-6printers=9printers[/tex]

Hence, we have that there are a total of 9 black and white printers.

To find the relationship between two quantities, x and y, in a table, analyze patterns in the changes of the values, determine if the relationship is linear or nonlinear, and then use the identified relationship to calculate missing values. A computer can be useful for plotting data and visualizing the relationship.

To find the relationship between two quantities, x and y, in a table, first, you need to look for a pattern in the way the numbers change. If y changes by a consistent amount when x changes by a set amount, the relationship is likely linear. If the rate of change itself changes, the relationship may be nonlinear. To determine the relationship:

The answer is B. If angle b is congruent to angle c, then you would write the problem as 12x + 4= 14x-2. X=3. You can check by substituting three for x.

Final answer:

To find the value of x in the isosceles triangle ABC with given angle expressions, we set the expressions for angles B and C equal, leading to a simple equation that yields x = 3.

Explanation:

The question involves finding the value of x in an isosceles triangle where the angles at base B and C are given as algebraic expressions in terms of x. Since triangle ABC is isosceles with angles at B and C being equal, we can set the expressions for m∆B and m∆C equal to each other and solve for x.

Let's set up the equation using the fact that m∆B = m∆C since ∆ ABC is isosceles:

(12x + 4)° = (14x - 2)°

We can then solve for x:

Subtract 12x from both sides: 4° = 2x - 2°

Add 2° to both sides: 6° = 2x

Divide by 2 to solve for x: x = 3

The value of x is therefore 3, which corresponds to answer choice B.

Answer:

Step-by-step explanation:

the equation of the graph  : y = sin(x + 90°)

because when :  x= 0 :  y = sin90° = 1

Answer:

Option A y = sin ( x + 90 )

Step-by-step explanation:

The given graph is the graph of cosine which should be in the form of

y = a cos ( bx + c ) + d

here a = amplitude = [tex]\frac{1-(-1)}{2}[/tex] = [tex]\frac{2}{2}[/tex] = 1

Since period of the wave is 2x or 360°.

we know, period = [tex]\frac{2\pi }{b}[/tex]

                          [tex]b=\frac{2\pi }{2\pi }[/tex] = 1

Now equation becomes,

y = cos ( x + c ) + d

In this graph there is no horizontal or vertical shift

c = 0 and d = 0

so equation will be  y = cos (x)

as we know              y = cos (x) = sin ( 90 + x )

Therefore, Option A y = sin ( x + 90 ) is the answer.

The angle between the longest side and the diagonal of the rectangle is approximately 30 degrees.

Trigonometric functions are defined as the functions which show the relationship between the angle and sides of a right-angled triangle.

To solve this problem, we can use the Pythagorean theorem and trigonometric functions.

First, we can find the length of the diagonal of the rectangle using the Pythagorean theorem:

diagonal² = longest side² + shortest side²

diagonal² = 1000² + 577²

diagonal = √(1000² + 577²)

diagonal = 1162.46 mm (rounded to two decimal places)

Next, we can find the angle between the longest side and the diagonal using the inverse tangent function:

tan(θ) = opposite / adjacent

tan(θ) = 577 / 1000

θ= arctan(577 / 1000)

θ= 29.98

θ ≈ 30 degrees

Therefore, the angle between the longest side and the diagonal of the rectangle is approximately 30 degrees.

Answer:

Three angles, measuring 25,65, and 90.

Step-by-step explanation:

When Dave walks three dogs he will earn a net profit of 40 dollars.

P(3) = 40 in the given problem context implies that Dave makes a net profit of 40 dollars from walking three dogs.

In the given problem context, the equation P(3) = 40 means that when Dave walks three dogs (d=3), he makes a net profit of 40 dollars. Dave's profit function is P(d) = 20d - 20. By substituting d with 3 in his profit function, we obtain P(3) = 20*3 - 20, which gives us P(3) = 60 - 20 = 40. Thus, Dave earns a net profit of 40 dollars from walking 3 dogs.
