Answer:
[(2*8) + 3] *4 = 76
[2*(8 - 3)]*4 = 40
Step-by-step explanation:
Los paréntesis ( ), corchetes [ ] y llaves {} son símbolos de agrupación que indican el orden de las cuatro operaciones aritméticas básicas (suma, resta, multiplicación y división). Las reglas del orden de operaciones establece que se debe realizar primero el cálculo dentro de los símbolos de agrupación.
En otras palabras, la jerarquía de operaciones es el orden en el que hay que realizar las distintas operaciones, ya que unas tienen prioridad frente a otras. Y establece primero debes empezar por resolver los paréntesis, luego los corchetes y finalmente las llaves. Es decir, cuando haya símbolos de agrupación dentro de símbolos de agrupación, calcula de adentro hacia afuera. Esto es, empieza simplificando los símbolos de agrupación en el centro.
Para obtener 76, se pueden realizar la siguiente operación combinada:
[(2*8) + 3] *4
Aplicando lo anteriormente mencionado de la jerarquía de operaciones, comienzas por resolver el paréntesis:
[16 + 3]*4
Ahora, resolviendo el corchete:
19*4
Finalmente, resolviendo la multiplicación:
19*4= 76
Entonces [(2*8) + 3] *4 =76
Para obtener 40, se pueden realizar la siguiente operación combinada:
[2*(8 - 3)]*4
Comenzando a resolver el paréntesis:
[2*5]*4
Ahora, resolviendo el corchete:
10*4
Finalmente, resolviendo la multiplicación:
10*4= 40
Entonces [2*(8 - 3)]*4 = 40
V 11. What is the result of multiplying 2.5 x 10 10 by 3.5 x 10 -7
Answer:
(2.5 x 10^10) x (3.5 x 10^-7) <--- When multiplying, numbers can be arranged in any order.
= (2.5 x 3.5) x (10^10 x 10^-7) <--- When you multiply numbers with the same base, add their exponents.
= 8.75 x 10^3
Step-by-step explanation:
a librarian arranges 4356 books in rows , such that the number of rows is equal to the number of books in each row , find the number of books in each row.
Answer:
66
Step-by-step explanation:
Given that:
Total Number of books = 4356
Number of books in a row = number of rows
Let number of rows = b
Then number of books in each row = b
Total number of books = (number of rows * number of books per row
Hence,
4356 = b * b
4356 = b²
Take the square root of both sides
Sqrt(4356) = b
66 = b
Number of books in each row = 66
A flat screen television measures diagonally 40 inches and 24 inches in length. What is the width of the television?
Answer:
The width of the Television is 32 inches.
Step-by-step explanation:
It seems as if the hypotenuse of the triangle is 40 inches, and one of the side lengths of it is 24 inches.
a2+b2=c2
So if we square 40 we get 1600, which is c2
If we square 24, we get 576, which is a2.
Then you solve, 576+b2=1600
you get b2=1600
Then you get the square root of both sides which in turn gives you the answer
b=32, which is the width of the television.
Step-by-step explanation:
use the pythagorean theorem c^2 = a^2 + b^2 diagonal is the hypotenuse...
40^2 = 24^2 + b^2
b^2 = 40^2 - 24^2
b =
[tex] b = \sqrt{40 {}^{2} - 24 {}^{2} } [/tex]

Answer:
[6, 10]
Step-by-step explanation:
Let the weight of a pen be x
Then its weight can be between
8 - 2 = 6 g and 8 + 2 = 10 g
This can be shown as
8 - 2 ≤ x ≤ 8 + 2
6 ≤ x ≤ 10
x = [6, 10]

LINES & LINE SEGMENTS ASSIGNMENT
Plot the following points on the number line below:
A: -25 B: -17 C: -13
D: -1 E: 4 F: 11
G: 16 H: 23 I: 25
Using the points and number line from the problem above, find each of the following. The first one is done for you.
a) BD = | -17 – (-1) | = | -17 + 1 | = | -16 | = 16
b) AE
c) EF
d) GI
e) CH
f) BG
g) CF
h) AC
Answer:
16, 29, 7, 9, 36, 33, 24, 12
Step-by-step explanation:
The distance between two points on a number line is the magnitude of the difference between their coordinates. In general, that means you can subtract the coordinate of the left point from the coordinate of the right point to find the distance.
Here, the points are in alphabetical order on the number line, left-to-right, as are the letters in the segment names. So you subtract the coordinate of the first point of the name from the coordinate of the last point in the name.
This is 8 simple subtraction problems.
a) D - B = -1 -(-17) = 16
b) E - A = 4 -(-25) = 29
c) F - E = 11 -4 = 7
d) I - G = 25 -16 = 9
e) H - C = 23 -(-13) = 36
f) G - B = 16 -(-17) = 33
g) F - C = 11 -(-13) = 24
h) C - A = -13 -(-25) = 12

Help answer this please!!!!!!!!!
Answer:
210 yards
Step-by-step explanation:
You are told that the two triangles (trails) are similar (since Perry wants to construct a similar trail to Hillsville's) this means that there is a scale factor meaning the length of one side of the Hillsville trail * scale factor = length of corresponding side of Perry's trail)
1. One side of the Hillsville trail that measures 400 yards corresponds to the 280 yard side of Perry's trail so the scale factor is
280/400 -> 7/10
2. Use the scale factor to find n since you know that the length of one side of the Hillsville trail * scale factor = length of corresponding side of Perry's trail
n = 300 * 7/10 -> n = 210

solve for x 3x+10 3x -28 will mark brainest answers are 1. 33 2. 34 3. 35 4. 36 ty so much 1 left godbless
Answer:
1. x = 33Step-by-step explanation:
3x+10 + 3x -28 = 180
3x + 3x = 180 + 28 - 10
6x = 198
x = 198/6
x = 33
Answer:
33
Step-by-step explanation:
By the same side interior angle theorem, we can find that 3x + 10 and 3x - 28 are supplementary. Knowing this, we can make the equation:
(3x + 10) + (3x - 28) = 180
Now we can solve for x. Combine like terms.
6x - 18 = 180
Add 18 from both sides.
6x = 198
Divide both sides by 6.
x = 33
So the value of x would be 33.
