Given 144= 12^2 which statement is true?

I’m I right ? If not can you correct me please

Answer:Steven used 9 $0.02 stamps and 6 $0.10 stamps

Step-by-step explanation:

let number of $0.02 stamp  be =x

let number of $0.10 stamp  be =y

so that the number of stamps used can be expressed as

x+y=15

and the total price of stamps used equaling  $0.78 be expressed as

0.02x + 0.10y =0.78

Solving

x+y=15----1

0.02x + 0.10y =0.78---2

from equation 1 ,  x =15-y, putting the value of x into equation 2

0.02(15-y) + 0.10y =0.78

0.3 -0.02y + 0.10y  = 0.78

0.3 + 0.08y=0.78

0.08y=0.78-0.3

y=0.48/0.08 =6

y =6 stamps

 Putting bthe value of  y =6 into equation 1

x+6=15

x=15-6 =9

Steven used 9 $0.02 stamps and 6 $0.10 stamps

Answer:

a. 4

Step-by-step explanation:

Copy and paste this:

I now that the area is: A = b×h/2, so: 16 = (x+4)(x)/2

-> x²+4x-32=0 -> x= -8 and x=4

x = -8 is impossible, so x=4

Answer: A. 4

Step-by-step explanation:

The equation for the area of a triangle is height times( base divided by 2)

4 + 4 = 8

8/2 is 4

4 times 4 is 16

Plate tectonics is a scientific theory describing the large-scale motion of the plates making up the Earth's lithosphere since tectonic processes began on Earth between 3.3 and 3.5 billion years ago. The model builds on the concept of continental drift, an idea developed during the first decades of the 20th century.

Answer:

A = 5,752.60

Step-by-step explanation:

P = $3,500

r= 5%

t = 10

k = 4

A = P(1 + r/k)^kt

= 3,500(1 + 0.05/4)^4*10

= 3,500(1 + 0.0125)^40

= 3,500(1.0125)^40

= 3,500(1.6436)

= 5,752.6

Step-by-step explanation:

The range of the function is {3, 7, -9}.

A relation between a collection of inputs and outputs is known as a function. A function is a connection between inputs in which each input is connected to precisely one output. Each function has a range, co-domain, and domain.

Given:

A function of x containing three ordered pairs of the form (x, y) is shown below. {(1, 3), (2, 7), (3, -9)}.

The range of the function is,

= the number of value in the y-coordinate.

= {3, 7, -9}

Therefore, {3, 7, -9} is the range.

Answer:

cosA = 8/17

Step-by-step explanation:

cos =  adjacent/hypotenuse

The number that is adjacent to angle A is 24 and the hypotenuse is 51

Plug the numbers into the cosine equation, which would look like:

Cos A = 24/51

You can simplify the fraction by dividing it by 3

So Cos A = 8/17 or 0.89130173...

Answer:

Divide the number of events by the number of possible outcomes. This will give us the probability of a single event occurring. In the case of rolling a 3 on a die, the number of events is 1 (there's only a single 3 on each die), and the number of outcomes is 6.

Answer:

La suma de cifras del producto original es igual a 12.

Step-by-step explanation:

De acuerdo a la información proporcionada, si multiplicas un número "x" por 32 su resultado sería igual al producto original "y" más 54 dado que dice que se obtiene un producto mayor en 54 al producto original, lo que se puede expresar de la siguiente forma:

32x=y+54

Además, se puede inferir a partir del enunciado que si el número x se hubiera multiplicado por 23 el resultado habría sido el producto original que lo denominamos como "y", por lo que puedes decir que:

y=23x

Ahora puedes reemplazar y=23x en 32x=y+54 y despejar x:

32x=23x+54

32x-23x=54

9x=54

x=54/9

x=6

Finalmente, puedes reemplazar el valor de x en y=23x:

y=23x

y=23*6

y=138

Suma de cifras: 1+3+8 = 12

Answer:

The diameter is 21 cm

Step-by-step explanation:

The formula for the volume of a sphere is V = (4/3)πr³, or (in terms of the diameter)  V = (4/3)π(d/2)³.  This simplifies to

       4πd³          πd³

V = ----------- = -----------

        3·8               6

Now equate V = (πd³/6) to 4851 cm³.  We must first solve this for d³ and then take the cube root of the result:

πd³ = 4851(6) = 29106.

Dividing this result by π yields 9264.7,

and taking the cube root of this is 21.  The diameter is 21 cm

Answer:

x = angle left of (4x+5) [ᴄᴏʀʀᴇsᴘᴏɴᴅɪɴɢ ᴀɴɢʟᴇs]

So, x + (4x+5) =180° [sᴜᴘᴘʟᴇᴍᴇɴᴛᴀʀʏ ᴀɴɢʟᴇs]

[tex](4x + 5 )+ x = 180 \\ 4x + 5 + x = 180 \\ 5x + 5 = 180 \\ 5x = 180 - 5 \\ 5x = 175 \\ x = \frac{175}{5} \\ x = 35[/tex]
