1. What is the slope of a line that is parallel to the line represented by the equation 3x + 4y = 12?

inn [45]

Answer:

Explained Below

Step-by-step explanation:

first we need to turn the equation into point slope form.

3x + 4y = 12

4y = -3x + 12

y = -0.75 + 3

Parallel lines don't have a change in slope because they run parallel. Your answer would be -0.75 or -3/4.

Tomas needs to cut a piece of wood for a model airplane he is building. He has four pieces of wood: 5 feet, 4 feet, 6 feet, and

blagie [28]

Answer:

Step-by-step explanation:

Alright, lets get started.

Tomas has four pieces of wood having each length = 5, 4, 6 and 3

The length of wood he needs to cut to make a model airplane = $\sqrt{11}$

Simplifying, it is 3.32 feet long

Means he needs more than 3 feet but less than 4 feet of wood piece.

So, he should select 4 feet length of wood because selcting 3 feet will not fulfilled to make his model and selcting 5 and 6 feet will have more unused wood.

4 feet piece of wood he should cut to have the least amount of unused wood. : Answer

Hope it will help :)

Please someone solve this problem <br>I really need answers

yulyashka [42]

Answer:

x = 50°

y = 50°

z = 80°

Step-by-step explanation:

working out x:

angles on a straight line add up to 180°

x + 130° = 180°

subtract 130 on both sides

x = 180° - 130°

x = 50°

working out y:

two vertical lines means that both sides are equal, so both angles are also equal (it's an isosceles triangle). This means that y is the same angle as x = 50°

y = 50°

working out z:

the sum of a triangle add up to 180°

add up the angles of x and y and equate to 180°

50 + 50 + z = 180

100 + z = 180

subtract 100 on both sides

z = 180 - 100

z = 80°

What number must be added to the expression below to complete the square? x^2+x. a.1/4 b.1/2 c.2 d.1

torisob [31]

Option a. 1/4 is the right answer

Step-by-step explanation:

Given expression is:

$x^2+x$

Here

we know that

a = x

In order to find the number which should be added

comparing with the formula

$(a+b)^2 = a^2+2ab+b^2$

$2ab = x\\2.x.b = x\\b=\frac{x}{2x}\\b = \frac{1}{2}$

So, we will add the square of 1/2 which is 1/4

Hence,

Option a. 1/4 is the right answer
