I WILL GIVE BRAINLIEST solve the question below

Answers

Answer:

[tex]J' = (-2,-4)[/tex]

Step-by-step explanation:

Given

The attached figure

[tex]J = (-3,-6)[/tex]

[tex]D_{o,\frac{2}{3}}(x,y)[/tex]

Required: Determine J'

The given transformation: [tex]D_{o,\frac{2}{3}}(x,y)[/tex] means that the quadrilateral is dilated by a scale factor or 2/3.

So, J' is calculated as:

[tex]J' = \frac{2}{3} * J[/tex]

[tex]J' = \frac{2}{3} * (-3,-6)[/tex]

[tex]J' = (\frac{2}{3} * -3,\frac{2}{3} * -6)[/tex]

[tex]J' = (2*-1,2*-2)[/tex]

[tex]J' = (-2,-4)[/tex]

Hence, J' = (-2,-4)

An insector found 24 defective cameras during an inspection. If this is 0.016% of the total numbers of cameras inspected. How many cameras were inspected?

Answers

Answer:

150,000.

Step-by-step explanation:

Given that an insector found 24 defective cameras during an inspection and this is 0.016% of the total numbers of cameras inspected, to determine how many cameras were inspected the following calculation must be performed:

0.016 = 24

100 = X

100 x 24 / 0.016 = X

2,400 / 0.016 = X

150,000 = X

Thus, the total number of cameras that were inspected is 150,000.

A sound wave travels at 330m/s and has a wavelength of 2 m. calculate its frequency and period.

Answers

Answer:

frequency= 165Hz

period= [tex]\frac{1}{165}[/tex]

Step-by-step explanation:

1. To calculate the frequency using the formula:

f = v/λ

where,

f=frequency (what the question asked)

v=speed of wave (given in the question=330m/s)

λ=wavelength (given in the question=2m)

SO,

[tex]f=\frac{330}{2}[/tex]

= 165Hz

2. To calculate the period use the formula:

since [tex]f=\frac{1}{T}[/tex]

therefore, [tex]T=\frac{1}{f}[/tex]

where,

f= frequency (what we solved above=165Hz)

T= period (what the question asked)

SO,

[tex]T=\frac{1}{165}[/tex]

2. Findcgiven m∠A=57° and a=22

Answers

Answer:

Step-by-step explanation:

Answer: c = 14.287 approximately

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

Work Shown:

Refer to the diagram below. Note how side a is opposite angle A, and side c is opposite angle C.

tan(angle) = opposite/adjacent

tan(A) = a/c

tan(57) = 22/c

c*tan(57) = 22

c = 22/tan(57)

c = 14.2869670503452

c = 14.287

This value is approximate. Make sure your calculator is in degree mode

a softball team has a budget of 200$ for visors. An athletic director pays $90 for 12 sun visors for the softball team. is there enough money in the budget to buy 15 more sun visors?

Answers

Answer:

Step-by-step explanation:

So if the director paid $90 for 12 visors, we need to find how much one cost so 90/12 = 7.5

Then to find the cost of 15 visors, multiply 7.5 by 15 to get 112.5

now add 112.5 to 90 to see if it stays within the budget of $200, 112.5 + 90 = 202.5, so NO there is not enough money in the budget to buy 15 more sun visors.

The ratio of cows to goats in a farm is 3:2 if there are 210 more cows than goats how many animals are there in the farm

Answers

Answer: 350 animals altogether.

Explanation: We need to find the number of goats and add that to the 210 cows.

Since we have a ratio, we can use the equation 3/2=210/x.

Cross multiplying gives us 3x=420, where x is 140 goats.

Finally, 140+210=350.

If (y + 1) varies directly as square root of x and y =14 when x = 27, find the value of y when
x = 64 without finding the variation constant.

Answers

Answer:

22.1 or 22

Step-by-step explanation:

Y + 1 varies√x

Y + 1 = K√x ( k is costant)

so we solve for K

given: 14 + 1 = K√27

15 = K√27

divide both sides by √27

15/√27 = K

to find the value of y

y + 1 = 15/√27 (8) : substitute K for 15/√27

Y + 1 = 120/√27

i.e Y = 120/√27 - 1

Y = 23.1 - 1

Y = 22.1 or 22

Can you help me here pls thx very much What is 52% of 25

Answers

Answer:

Step-by-step explanation:

52% of 25 is 13. Write 52% as 52/100
Since, finding the fraction of a number is same as multiplying the fraction with the number, we have 52/100 of 25 = 52/100 x 25 so the answer is 13. Now if you’re using a calculator just do 52/100x25 which would give you 13 just using a different and faster way.

Which proportion best compares age and tattoos?

The row data represents the age range of each group while the column data represents the amount of tattoo by each group.

So, to make comparison:

You simply pick a cell data and compare it to the row total.

Take for instance

For those who have at least 1 tattoo. The proportion to use are:

170/490 --- For age range: 18 - 29

60/505 --- For age range: 30 - 29

For those without tattoo. The proportion to use are:

320/490 --- For age range: 18 - 29

445/505 --- For age range: 30 - 29

Bochica, el maestro de los chibchasBochica, anciano de barba largaLa tradicin juega un papel muy importante en la cultura colombiana, sobre todo en las actuales comunidades indgenas cuyas costumbres poco tienen que ver con las tradiciones cristianas. Una de estas tradiciones que encontr en una fuente que parece fidedigna y seria cuenta la historia de uno de los dioses ms importantes de los Chibchas que habitaban la zona del altiplano cundiboyacense. De todas formas, en mi opinin, la historia contiene demasiadas coincidencias con la religin catlica, algo que parece poco probable debido al hecho de hablar de una cultura totalmente diferente de la nuestra y la poca mucho ms antigua de la llegada de los espaoles cristianos a las tierras americanas.El relato cuenta que en los tiempos remotos cuando todava la Luna no acompaaba a la Tierra en la meseta colombiana viva el pueblo Chibcha. Vivan en una tierra prdiga que sin mucho esfuerzo daba dos cosechas al ao. Los Chibchas se desarrollaron muy rpido y pronto olvidaron de sus dioses. Dejaron de trabajar, peleaban mucho entre s y solo se ocupaban de los placeres. En esta situacin, Chia, la diosa de la noche, pidi un fuerte castigo para ellos, pero Su, el Sol y Bachu, la Naturaleza, decidieron darles otra oportunidad. Soplaron sobre la Tierra y engendraron una parte de su deidad en el vientre de una mujer pura y hermosa, esposa de un artesano. De este soplo divino naci un nio al que llamaron Bochica, hijo del Cielo.Bochica creci como un dios civilizador de los indgenas, les ense a los indgenas a sembrar, a fabricar casas, a tejer en algodn y el fique, a cocer el barro y hacer ollas, a construir redes para coger los peces en los lagos y en los ros, a fabricar arcos y flechas para cazar en los bosques, les dio el calendario, cdigos de respeto, de convivencia y les ense a amar los dioses. Cuando el pueblo empez a vivir tranquilo, Bochica desapareci. Pero no haba pasado mucho tiempo, cuando los Chibchas volvieron a sus malas costumbres. Para castigarlos los dioses enviaron una sequa tremenda y luego una inundacin. Cuando las aguas bajaron, los pocos sobrevivientes vieron llegar entre la bruma que se levantaba al amanecer, un anciano de larga barba que caminaba ayudndose con un bastn.Bochica otra vez se ocup de su amado pueblo. Le regalo el fuego que sec sus ropas, que cocin sus alimentos, que les calent en las noches y se qued con ellos. Cuando sinti que se le acercaba la muerte, se escondi en la montaa.Despus de la muerte del dios ocurri algo increble. El monte empez a emanar un brillo profundo como el fuego que Bochica haba entregado a sus hombres despus del diluvio. Las piedras brillaban, pero no de color rojo, sino verde como la selva y como el agua de la laguna. Este era el alma de Bochica y su tumba se haba transformado en un inmenso depsito de esmeraldas. Esta es la historia del Bochica, un anciano de barba larga y blanca, de piel blanca y ojos azules, envuelto en una manta grande que lo cubra hasta los pies y con una varita de oro en la mano que sacrific su vida para darles lo mejor a su amado pueblo Chibcha y para quedarse en su memoria para siempre.Tomado de: inemvillavicencio.edu.co/page/images/2012/.../precolombia8.pdfLas anteriores lecturas pertenecen al grupo indgena Muisca, el cual se estableci en el altiplano cundiboyacense.
