what is the arc length of a semicircle with a diameter of 8

Answer:

C. 7.2

Step-by-step explanation:

Hope it helps you in your learning process.

Answer:

3 ft 3 in

Step-by-step explanation:

The radius is half the diameter.  

If the diameter is 6 ft 6 in, then the radius is 3 ft 3 in.

Answer:

33ft^2

Step-by-step explanation:

Answer:

15

Step-by-step explanation:

Answer & Step-by-step explanation:

[tex]Circumference=d\pi[/tex]

The diameter of the circle is 24 mm. So, let's add in the diameter and find the circumference of the circle.

[tex]Circumference=(24)\pi[/tex]

We will use 3.14 for pi.

[tex]Circumference=75.36[/tex]

So, the circumference of the circle is 75.36 mm.

Answer:

4425.7

Step-by-step explanation:

Answer:

Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.

Step-by-step explanation:

First of all we know that the total surface are that Calvin is painting is 115 square feet.

The rate at which Calvin is painting refers to the surface area he covers every 2 minutes. This is 2.5 square feet every 2 minutes.

we can set up a relation to solve this problem

If Calvin paints [tex]2.5 ft^{2}[/tex] in 2 minutes

He will paint [tex]115 ft^{2}[/tex] in [tex]x[/tex] minutes

By cross multiplying, we have [tex]x= \frac{2 \times 115}{2.5}=92 minutes[/tex]

Hence Calvin will paint the entire area in 92 minutes or 1 hour 32 minutes.

Answer:

2/3

Step-by-step explanation:

There are 3 odd numbers in a dice which equals 1/2. Then there is 1/6 of a chance of rolling a 3. So it would be 1/2 + 1/6=4/6 which simplifies to 2/3.

Answer:

The y-intercept is 2.

Step-by-step explanation:

We can find the y-intercept by looking at the linear equation y = mx + b.

m = slope

b = y-intercept

====================================================

Let's find the y-intercept of this line.

You should notice that the equation is written in Slope-Intercept Form:

[tex]\bigstar{\boxed{\pmb{y=mx+b}}}[/tex]

Where

m -> slope

b -> y-intercept

In the equation y=mx+b, the y-intercept is b, and in the equation y=3x+2, 2 is the y-intercept.

=========================================================

Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)

Answer:

18 sprinkles

Step-by-step explanation:

20% of 90 cupcakes

20% = 1/5

1/5 of 90

1 x 90 = 90

90 / 5 = 18

Answer:

18 cupcakes

Step-by-step explanation:

If there were 90 cupcakes and 20% of the cupcakes had sprinkles on top, the number of cupcakes with sprinkles on top would be

⇒ 20% of 90 cupcakes

⇒ [tex]\frac{20}{100} * 90 cupcakes[/tex]

⇒ (2*9) cupcakes

⇒ 18 cupcakes

1.rs 2.yoy can just put the q with the t and when you subtract it can problabbly go to thr letter a

Answer:

1. R and S

2. Both equidistant from 0

3. Move six spots to the left of T because each spot is 1/4, and 1 1/2 = 6/4, and it is a subtraction problem.

Step-by-step explanation:

Answer:

4(t+25) = (t+50) - 4 (0.15t)

4t + 100 = t + 50 - 0.6t

4t + 100 = 50 + 0.4t

4t - 0.4t + 100 = 50 + 0.4t - 0.4t

3.6t + 100 = 50

3.6t + 100 - 100 = 50 - 100

3.6t = -50

3.6t / 3.6 = -50 / 3.6

t = - 13.9

Answer: y= -x - 4

Step-by-step explanation:

Answer:

La distancia en línea recta que separa los segmentos paralelos es 60cm.

Step-by-step explanation:

Esta pregunta se puede resolver usando el teorema de Pitágoras:

[tex] \\ c^2 = a^2 + b^2[/tex] [1]

Es decir, en triángulos rectágulos, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los catetos de dicho triángulo. Un triángulo es rectángulo cuando el ángulo que forman sus dos catetos es recto o de 90 grados sexagesimales.

Es importante notar que la letra N tiene dos lados paralelos y el lado oblicuo (o inclinado) une ambos lados paralelos. Pues bien, la letra N puede formar dos triángulos iguales. Escojamos uno de ellos para obtener la respuesta, es decir, la distancia en línea recta que separa los segmentos paralelos (segmentos verticales de la N)

El lado oblicuo (inclinado) es la hipotenusa de ese triángulo (es decir, c). De los catetos, uno está representado por uno de los segmentos paralelos (verticales) de la N (digamos que es b), y, el otro cateto, es la distancia horizontal que une ambos segmentos verticales (digamos que es a).

Si unimos el segmento inferior del cateto b con el extremo inferior de la hipotenusa, se forma el cateto a. Este cateto a forma un ángulo recto con el cateto b y, por lo tanto, forma un triángulo recto. Los lados de un triángulo recto pueden resolverse usando el teorema de Pitágoras, descrito en [1].

Usando [1] y despejando a, tenemos:

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

Restamos [tex] \\ b^2[/tex] de ambos lados de la igualdad:

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

[tex] \\ c^2 - b^2 = a^2 + 0[/tex]

[tex] \\ c^2 - b^2 = a^2[/tex]

Luego

[tex] \\ a^2 = c^2 - b^2[/tex]

Extrayendo la raíz cuadrada en cada lado de la igualdad:

[tex] \\ \sqrt{a^2} = \sqrt{c^2 - b^2}[/tex]

Entonces

[tex] \\ a = \sqrt{c^2 - b^2}[/tex]

Asimismo, tenemos que [tex] \\ c = 65[/tex]cm y [tex] \\ b = 25[/tex]cm

Entonces,

[tex] \\ a = \sqrt{65^2 - 25^2}[/tex]

[tex] \\ a = \sqrt{4225 - 625}[/tex]

[tex] \\ a = \sqrt{3600}[/tex]

[tex] \\ a = 60[/tex]cm

De esta manera, el valor de a, o la distancia en línea recta que separa los segmentos paralelos, es 60cm.

Podemos comprobar el resultado anterior haciendo uso del mismo teorema de Pitágoras:

[tex] \\ 65^2 = 60^2 + 25^2[/tex]

[tex] \\ 4225 = 3600 + 625[/tex]

[tex] \\ 4225 = 4225[/tex]

Answer:

sphere

Step-by-step explanation:

Human heads are close to circles and sometimes are circles

Sphere is the best model for the head of a human being.

A human head definitely doesn't represent a Cone neither a Pyramid.

Now a cylinder is a solid which is circular at its edges and straight in its length which clearly does not model the human head. Now the Sphere, it does closely represent the outside figure of a human head.  

Thus Sphere is the best model for a human head.

Therefore option D, sphere is the correct answer.

Step-by-step explanation:

2/5 were sold out

5/5 - 2/5 = 3/5

That means 3/5 were not sold out

p = performances

there were 15 that were not sold out

3/5 * p = 15

Multiply each side by 5/3

5/3 *3/5 p = 15*5/3

p = 25

There were 25 performances
