Answers

Answer 1

Answer:

Efectivamente, si se suman los resultados de la tabla del 2 con los de la tabla del 5 se obtienen los resultados de la tabla del 7.

Step-by-step explanation:

Esto es así porque 7 puede formarse a través de diversas sumas (7+0, 6+1, 5+2 o 4+3). Por ende, en el caso de las tablas de multiplicaciones, decir, por ejemplo, 7 x 3, es igual a decir 5 x 3 + 2 x3, dado que 5 + 2 es igual a 7.

Entonces, siguiendo el ejemplo, dado que 7 x 3 es igual a 21, la suma de 5 x 3 igual a 15 y 2 x 3 igual a 6 es 21 (15 + 6), con lo cual la afirmación es correcta.

Answers

Answer:

D. 150

Step-by-step explanation:

X = W/5

X + W = 180

*If X = 30, and W = 150:

30 = 150/5

A. 71

B. 84

C. 29

D. 67

Answers

Step-by-step explanation:

angle on a straight line is 180, thus , the angle on the line inside the triangle is

180 - 96 = 84

and since the sum of the angles in a triangle is 180 ,

the angle 1 is ..

180 - 29 - 84 = 67 degrees ,

therefore the answer is D

hope this helps

the answer is d. 67 degrees

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

b² + 5² = 13²

b² + 25 = 169 ( subtract 25 from both sides )

b² = 144 ( take the square root of both sides )

b = [tex]\sqrt{144}[/tex] = 12

PLZ HELP I WILL MARK BRAINLIEST A rectangular prism has a base that is 5 cm by 7 cm and a height of 12 cm. If all dimensions are doubled, what happens to the volume? When the dimensions are doubled, the volume is twice the original volume. When the dimensions are doubled, the volume is three times the original volume. When the dimensions are doubled, the volume is four times the original volume. When the dimensions are doubled, the volume is eight times the original volume.

Answers

Answer:

When the dimensions are doubled, the volume is eight times the original volume.

Step-by-step explanation:

difference in volume = volume of prism with dimensions doubled / original volume of prism

Volume of a prism = length x width x height

original volume of prism = 7 x 5 x 12 = 420

doubled dimensions of  prism = (7x2) x (5x2) x (12 x 2)

volume = 14 x 10 x 24 = 3360

3360 / 420 = 8

Answer: D When the dimensions are doubled the volume is eight times the original volume​

[tex]2x^2+x+7y[/tex]

Step-by-step explanation:

We are given the equation [tex]2(x^2+3y)+x+y[/tex] and are asked to simplify it.

To do so, we need to first get rid of the parenthesis, since x² and 3y aren't like terms, it isn't solvable unless we try another way, which is the distributive property.

2 is next to the parenthesis, in the distributive property, we would multiply the number outside of the parenthesis with all the numbers inside the parenthesis. Therefore :

[tex](2*x^2) + (2*3y) + x +y[/tex]

[tex]2x^2 +6y+x+y[/tex]

Now that we have like terms, we can add them together :

[tex]2x^2 + 6y+x+y[/tex]

[tex]2x^2 + x+7y[/tex]

A fitness center charges $3 per visit plus a monthly fee of $30. How much would it cost in one month if Ella has 18 visits?
$48
$54
$84
$90

Answers

Answer:

84$

Step-by-step explanation:

It says it costs $3 per visit and Ella went 18 times

So we can describe that as x represents the times she has visited, x=18, so 3(18)

now we just add $30 dollars since she only went in one month and $30 is the fee per month so that would be (3*18=) 54+30

which would then give you $84 dollars!
