126÷2=63
Answer: area of 63
Step-by-step explanation: the formula is Area = height * base/2
so now substitute Area = 9 * 14/ 2
multiply... Area = 126/ 2
then divide to get 63

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)
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.

Three research departments have 8,6,7 members, respectively. Each department is to select a delegate and an alternate to represent the department at a conference. In how many ways can this be done
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

Link or something. It's has been a nightmare with these questions...
Answer:
Part B
Part 1 describes a quartic function that's been reflected over the x-axis and translated up and to the right. (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. (This one looks just like Part 3 in the previous graph.)Part C
You're going to have to do this scatter plot on your own with the given software, because I don't know how your software works, but I can tell you that #1 will look like a quadratic, #2 a cubic, #3 a quartic, #4 a really fun third root that looks like a cubic on the y-axis instead of the x-axis.
Part D
You can look on Worldometer for graphs of the coronavirus; they have graphs in every individual country. I advise using the total cases on a logarithmic scale, because the question specified that it can't be linear.
what is the solution for 1/2x + 8 < 10
1/2x+8<10
-8 -8
1/2x<2
*2 *2
x<4
Answer:
x<4
Answer:
x < 4
Step-by-step explanation:
Given inequation,
→ 1/2x + 8 < 10
Now the value of x will be,
→ 1/2x + 8 < 10
→ 1/2x < 10 - 8
→ x < 2 × 2
→ [ x < 4 ]
Hence, the value of x is 4.
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?
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

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?
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

Answer this to be called the smartest...... What has 4 lags in the morning, 2 in the afternoon, and 3 at night..?
Answer:
A person
Step-by-step explanation:
I have heard this riddle multiple times, it is very well known and ( in my opinion ) very intriguing;
If we are considering the 4 legs in the morning, we can assume it to be a baby crawling on all 4's. 2 legs in the afternoon represents a more elderly person, a young child or adult on their 2 legs, and 3 in the night models an elderly person, using a walking stick as their " leg "
Answer; In other words, a person has 4 legs in the morning, 2 in the afternoon, and 3 at night
A human is one who has 4 legs in the morning, 2 in the afternoon, and 3 at night.

The result for the survey of 120 students who were selected randomly is listed below. The total population of students was 380. 66 students ride the yellow bus 24 students ride the city bus 30 students do not ride a bus . Based on the data, what is the best approximate for the total number Of students who ride the city bus?
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
