Answer:

14

Step-by-step explanation:

d=c/pi

45/pi=14

Answer:

14

Step-by-step explanation:

c = pi d

45 = 22/7 d

45 * 7/22 = d

2* 7      = d (approx.)

d = 14 approxiamtely

So the closest estimate dor d is 14

Answer:

5.592

Step-by-step explanation:

Answer:

the answer is 1,194

Step-by-step explanation:

what you want to do is find the area of 2 triangles and 3 rectangles

area of 1st rectangle

1 = ae

=(22 ft) (19 ft)

=418 sq. ft.

area of 2nd rectangle

2 = ab

=(22 ft.) (14 ft.)

=308 sq. ft.

area of 3rd rectangle

3=ad

=(22 ft.) (13 ft.)

=286 sq. ft.

area of 1st triangle

Area of triangle =  1/2 cb

=1/2 (13ft) (14ft)

= 1/2 (182 sq. ft)

=91 sq. ft.

***this would be the same for 2nd triangle*** 91 sq ft.

Next add all areas together to get the total surface area

Total surface area = ae + ab + ad + 2 (1/2 cb)

= 418 sq. ft + 308 sq. ft. + 286 sq. ft. + 2(91 sq. ft)

=418 + 308 + 286 + 182

= 1,194 sq. ft.

It's the second option.

y = -2 sin x + 2

Tell me if I'm wrong :)

It looks spiker because my graph is more spread out with the intervals.

Answer: b) y = -2 sin x + 2

Step-by-step explanation:

The standard equation for a sine graph is: y = A sin (Bx - C) + D

[tex]\text{Amplitude (A) = }\dfrac{max-min}{2}=\dfrac{4-0}{2}=\dfrac{4}{2}=2\\\\\\\text{Vertical Shift (D) = max - amplitude = }4 - 2 = 2[/tex]

A sine graph starts at the origin and tends upward.  The given graph stars at the origin and tends downward so it is a reflection → - sin x

⇒ y = -2 sin x + 2

The factored form of the given expression is 14(10c + 2 - a).

Given is an expression 140c + 28 - 14a, we need to factor it to simplify in equivalent expression.

We search for common term that can be eliminated in order to factor the expression 140c + 28 - 14a.

In this instance, we may factor the terms that share a common factor of 14 out.

The expression changes to:

140c + 28 - 14a

Let's now subtract 14:

14(10c + 2 - a)

Therefore, the expression's factored form is 14(10c + 2 - a).

ANSWER

[tex]x \: < \: 9[/tex]

EXPLANATION

The given inequality is

[tex]5x \: < \: 45[/tex]

We divide through by 5 to get:

[tex]x \: < \: \frac{45}{5} [/tex]

This will simplify to

[tex]x \: < \: 9[/tex]

Therefore the solution to the inequality is

[tex]x \: < \: 9[/tex]

x < 9

Start with 5x < 45.

Divide both sides of the inequality by 5 to get x < 45 / 5, or x < 9.

To solve the given system of linear equations -3x = 42-16y and 14x = 76-16y, use the method of elimination to find the solution (20-6y, y).

To solve the system of linear equations -3x = 42-16y and 14x = 76-16y, we can use the method of substitution or elimination. Let's use the method of elimination:

Multiply the first equation by 2 to make the coefficients of y in both equations equal. The equations become:

-6x = 84-32y and 14x = 76-16y

Add the two equations together:

-6x + 14x = 84-32y + 76-16y

Simplify:

8x = 160-48y

Rearrange the equation to solve for x:

x = (160-48y)/8

Simplify further:

x = 20-6y

The solution to the system of equations is x = 20-6y. To separate the x- and y-values, we write it as (20-6y, y).

Quadrilateral. If you add the angles up on any quadrilateral, it equals 360 (it should always add to 360 for a quadrilateral)

The polygon you're describing is a kite.

To verify this, let's calculate the sum of the interior angles of the polygon:

Sum of interior angles = [tex](n - 2) * 180 degrees[/tex]

For a polygon with 4 sides: [tex](4 - 2) * 180 = 360 degrees[/tex]

Now, let's add up the given angle measures: 80 + 100 + 80 + 100 = 360 degrees

Since the sum of the interior angles matches the calculated sum for a four-sided polygon, and the sides are congruent, the polygon is indeed a kite.

1. Calculate the sum of interior angles: The sum of interior angles of any polygon can be found using the formula (n - 2) * 180 degrees, where 'n' represents the number of sides. For a four-sided polygon, the sum is (4 - 2) * 180 = 360 degrees.

2. Add up the given angle measures: The given angle measures are 80, 100, 80, and 100 degrees. Adding them together gives a total of 360 degrees, which matches the sum calculated for a four-sided polygon.

3. Confirming the polygon type: Since the sum of the interior angles matches the calculated sum for a four-sided polygon, and the sides are congruent (meaning all sides have the same length), the polygon fits the definition of a kite.

Therefore, the polygon with four congruent sides and angle measures of 80, 100, 80, and 100 degrees is indeed a kite.

What is the name of a polygon that has four congruent sides and these angle measures 80,100,80,100

Step-by-step explanation:

Since these angles are supplementary, they add up to 180°.

Let's make an equation.

[tex]360=(x+23)+(2x+4) \\ \\ 360=x+23+2x+4 \\ \\ 360=3x+27 \\ \\ 3x=333 \\ \\ x = 111[/tex]

Answer:

[tex]x=51[/tex]

Step-by-step explanation:

We have been given an image of two intersecting lines. We are asked to find the value of x.

We can see that both angles are supplementary, so we can set an equation as:

[tex]x+23+2x+4=180[/tex]

[tex]x+2x+4+23=180[/tex]

[tex]3x+27=180[/tex]

[tex]3x+27-27=180-27[/tex]

[tex]3x=153[/tex]

[tex]\frac{3x}{3}=\frac{153}{3}[/tex]

[tex]x=51[/tex]

Therefore, the value of x is 51.

Answer:

the sine of angle R is 5/7.

Step-by-step explanation:

Recall that the sine function is defined as sin Ф = (opposite side) / hypotenuse.

The side opposite Angle R is √65 and the hypotenuse is √91.

Thus, the sine of angle R is sin R = √65 / √91, or 5/7.

I believe the answer is 14.42

The length of AC is 14.42 in the triangle ΔABC where AB=17cm, BC=9cm and angle ∠ACB=90°. This can be obtained by using Pythagoras' theorem.

Given that, AB=17cm, BC=9cm and angle ∠ACB=90°.

By using Pythagoras' theorem,

AB² = AC²+BC²

17² = AC²+9²

AC² = 17²-9² =289-81 = 208

AC = √208 =14.42

⇒AC = 14.42cm

Hence the length of AC is 14.42 in the triangle ΔABC where AB=17cm, BC=9cm and angle ∠ACB=90°.

By testing these values in the equation, we can find that the only rational root is x = 2.

Answer:

19.50 divided by 3

Step-by-step explanation:

Answer:

3h = 19.50

Step-by-step explanation:

First lets define the price of each hat as the variable h.

Next we know that there are 3 hats so we can write that variable as 3h

We also know that the cost of all 3 hats was $19.50. This means that we can set each side of this equation equal to each other.

This gives us the equation 3h = 19.50

If you were to solve for h, you would get

[tex]h = \frac{19.50}{3}[/tex]

Which would simplify to

h = 6.50

This means that each hat costs $6.50

Step-by-step explanation:

The correct form is:

4sin^2 x − 1 = 0

First step is add 1 to both sides:

4sin^2 x-1+1=0+1

4sin^2 x=1

Now to eliminate 4 divide both sides by 4

4sin^2 x/4=1/4

sin^2 x=1/4

Take square root at both sides

√sin^2 x = √1/4

sinx = 1/2

Thus the correct option is 30° ....

Step-by-step explanation:

Angle BAE is 40 degrees

All angles at the crossing of BE and AC are right angles (90 degrees) because they are perpendicular lines.

Since BE is a bisector of angle ABC, we know that angles ABD and DBC are equal.

We don't know angle ABD but it's easy to find... since we know 2 angles from triangle ABE, and the sum of the interior triangles is 180.  So,

ABD = 180 - 40 - 90 = 50

Since ABD is 50 degrees and represents half of angle ABC... we know that ABC is 100 degrees.
