a right cone has a surface area of 628 cm squared and a diameter of 10cm what is the slant length

Answers

Answer 1

Answer:

slant length = 35 cm

Step-by-step explanation:

A right cone has the vertex directly above the center of the base . The surface area of the right cone can be represented below.

surface area = πr(r + l)

where

r  = radius

l = slant height/length

surface area = πr(r + l)

r = 10/2 = 5 cm

surface area = 628 cm²

Therefore,

628 = π × 5(5 + l)

628 = 5π(5 + l)

628 = 25π + 5πl

628 = 25 × 3.14 + 5 × 3.14 × l

628 = 78.5 + 15.7l

628 - 78.5 = 15.7l

549.5 = 15.7l

divide both sides by 15.7

l = 549.5/15.7

l = 35 cm

slant length = 35 cm

Coach Walker wants to buy equal numbers of footballs and basketballs for her PE class. The footballs cost $9 each, and the basketballs cost $7 each. Coach Walker has $208 for the purchase. How many of each type of ball can she buy?

Answers

Answer:

13 footballs and 13 basketballs

Step-by-step explanation:

Let f = footballs

b = basketballs

f=b since we are buying an equal number

9f+7b = 208

Substitute f=b

9f+7f = 208

16f = 208

Divide by 16

16f/16 = 208/16

f=13

We are buying 13 footballs

Since f=b

We are buying 13 basketballs

Un faro enciende cada 12 segundos, otro cada 18 segundos y un tercero cada minuto. A las 7:30pm los tres coinciden. Averigua a qué hora vuelven a coincidir los 3. (Siga el formato de hora correcto. Por ejemplo: 7:30pm. Sin espacios)

Answers

Answer:

7:33 p.m.

Step-by-step explanation:

Para resolver este problema, necesitamos encontrar el mínimo común múltiplo de los intervalos en los cuales se encienden los faros. Para eso necesitamos primero convertir el tiempo que tarda el tercer faro en segundos. Sabemos que cada minuto tiene 60 segundos en total, así que el tercer faro se encenderá cada 60 segundos.

Luego de tener todos los tiempos en segundos, procedemos a escribirlos en una tabla como la siguiente:

12   18   60

La idea es buscar los números primos que todos tengan en común y dividirlos todos entre dichos números primos hasta que ya no podamos dividirlos más, por ejemplo, estos números se pueden dividir todos dentro de 2 así que hacemos eso:

12  18   60  |  2

6   9    30  |  2   dos de estos números nuevos pueden ser dividos entre dos también, así que hacemos justo eso.

12  18   60  |  2

6   9    30  |  2

3   9    15   | 3   ahora todos pueden ser divididos entre 3, así que obtenemos:

12  18   60  |  2

6   9    30  |  2

3   9    15   | 3

1    3     5   |  3    uno de estos números se puede dividir entre 3 y obtenemos.

12  18   60  |  2

6   9    30  |  2

3   9    15   | 3

1    3     5   |  3

1    1      5   |  5  y finalmente dividimos entre 5 para obtener:

12  18   60  |  2

6   9    30  |  2

3   9    15   | 3

1    3     5   |  3

1    1       5   |  5

1    1       1    

luego que terminamos la tabla tomamos todos los números que usamos para dividir y los multiplicamos entre si para obtener:

2*2*3*3*5=180s

los tres focos se volverán a prender luego de 180s. Si pasamos los 180s a minutos, tenemos que:

[tex]\frac{180}{60}=3min[/tex]

entonces lo único que tenemos que hacer es sumarle esos 3 minutos a la hora que nos dieron originalmente para obtener:

7:30 + 3 min = 7:33pm

la cual es nuestra respuesta.

(It's quartic because it has those bumps; it's like a quadratic in that its end behavior is down-down, but it has more bumps than a quadratic.)Part 2 describes an exponential decay function that approaches a horizontal asymptote.

PLEASE HELP!! The cost for parking in the local covered parking lot is calculated by ƒ(h) = 4.5 + 1.5⌈(h - 1)⌉ where h is the number of hours you parked. What is the cost for parking in the garage for 75 minutes?

Answers

Answer:

The cost of parking in the garage for 75 minutes is 4.875.

Step-by-step explanation:

The costs of parking h hours is given by the following function:

[tex]f(h) = 4.5 + 1.5(h-1)[/tex]

Cost of parking 75 minutes.

1 hour is 60 minutes. How many hours are 75 minutes?

1h - 60 min

xh - 75 min

[tex]60x = 75[/tex]

[tex]x = \frac{75}{60}[/tex]

[tex]x = 1.25[/tex]

75 minutes is 1.25 hours. So we have to find f(1.25).

[tex]f(1.25) = 4.5 + 1.5*(1.25-1) = 4.875[/tex]

The cost of parking in the garage for 75 minutes is 4.875.

How do you find the mean of a data set ?

Answers

Step-by-step explanation:

You have to add up all the data values and then divide it by how many numbers there are. For example:

1,2,3,4,5,6,7

1+2+3+4+5+6+7= 28

There are 7 numbers, so 28/7 equals 4

Mean= 4

Add up all the numbers and then divide that number by how many there are.
Ex: data set of 3,5,7,8
Add together 3+5+7+8=23
Divide 23/4=5.75
5.75 is your mean

The chance of getting 4 or 5 (not factors of 6) is [tex]\frac{2}{6} =\frac{1}{3}[/tex] chance.

(None of the options you gave is correct)

The probability of getting numbers which is not a factor of 6.

Probability :

The numbers on die which is factors of 6 is,

                               1,2,3,6

So that, numbers on die which is not factor of 6 is, 4 and 5.

We have to find probability that  the score is not a factor of 6.

Total number of favorable outcomes = 2

Total outcomes = 6

Answers

Answer:

70,560 ways

Step-by-step explanation:

This problem is an arrangement problem, as the order of the two people chose in each department matters.

So, for each department, we have an arrangement:

First department: arrange of 8 choose 2: A(8,2) = 8!/2! = 8*7 = 56

Second department: arrange of 6 choose 2: A(6,2) = 6!/2! = 6*5 = 30

Third department: arrange of 7 choose 2: A(7,2) = 7!/2! = 7*6 = 42

The total number of ways is the product of each number of arranges, so:

Number of ways = 56 * 30 * 42 = 70,560

In a capture-recapture study, 97 grizzly bears were tagged and released back into the wild. A month later, 200 bears were captured of which 36 were tagged. About how many grizzly bears are in the population?

Answers

Answer:

539

Step-by-step explanation:

Let the total population of  grizzly bears=x

In the first capture, 97 were tagged.

Therefore, ratio of the total population to the tagged=x:97

A month later, when 200 bears were captured, 36 were tagged.

Ratio of the sample to the tagged=200:36

Since a sample is representative of the population, the ratios are the same. We therefore have:

x:97=200:36

[tex]\dfrac{x}{97} =\dfrac{200}{36}\\ $Cross multiply\\36x=200 X 97\\x=200 X 97 \div 36\\x=538.9 \approx 539[/tex]

There are about 539 grizzly bears in the population

The result for the survey of 120 students who were selected randomly is listed below.

Based on the data, what is the best approximate for the total number Of students who ride the city bus?

Answers

Answer: 76 students

Step-by-step explanation:

Number of students surveyed = 120

Students who 66 ride yellow bus= 66

Students ride city bus = 24

Students who do not ride a bus = 30.

The fraction of students who ride the city bus will be:

= 24/120

= 1/5

Since the total population of the students is 380, the qpproximate for the total number of students that ride the city bus will be:

= 1/5 × 380

= 76 students
