When a line L is perpendicular to two lines on the plane that intersects line L , then line L is perpendicular to the plane.

We know that two lines are perpendicular to each other if they intersects and these two lines are inclined at angle 90° (right angle)

Perpendicular lines are intersecting lines.

Mathematically, the perpendicular lines are represented by the symbol, ‘⊥‘.

When a line is perpendicular to two lines on the plane then it is perpendicular to the plane.

We can say that when the line L is perpendicular to every line in the plane that intersects line L, then we can say that a line and a plane are perpendicular.

Order of addends has no bearing on the amount according to the commutative property of addition. 6 added value.

The machine below produces a different number when a number is entered. 9 is produced if 3 is inserted. If 6 is put in, 12 will come out. If 7 is put in, 13 will come out. ​

Order of addends has no bearing on the amount according to the commutative property of addition.

Changing the addends' order does not alter the amount, according to the commutative property of addition.

Every output number, as we can see, adds a value of 6 to the corresponding input number.

Answer: The total clockwise moment of the weight of the diving board and the weight of the girl at about Point A can be calculated using the equation:

moment = force x distance

In this case, the force is the weight of the diving board (800 N) and the weight of the girl (600 N) and the distance is the distance from Point A to the support (2.5m).

So the total clockwise moment is:

moment = (800 N + 600 N) x 2.5 m = 1400 N x 2.5 m = 3500 Nm

The unit for moment is Newton-meter (Nm).

It's worth noting that in this problem, the clockwise moment is calculated by considering the force and the distance in the same direction, and the moment is positive, if the force is acting in a clockwise direction.

Answer:

x = 2

y = 5

Step-by-step explanation:

Brainly doesn't provide online graphing tools, so I will try to walk you through what to do.

First put both equations in slope-intercept form:

y + x = 7  →  y = -x + 7

3y - 6x = 3   →   3y = 6x + 3  →  y = 2x + 1

These are easy to graph now.  

For equation (1), place a point on the y-intercept (0,7), then draw a line with a slope of -1  (down one, over one, down one, over one, etc.).  The x-intercept is (7,0).

For equation (2), the y-intercept is point (0,1).  Draw a line with a slope of 2 (up 2, over 1, up 2, over 1, etc.)  The x-intercept is (-1/2, 0).

Where the 2 lines intersect is the solution.  They should intersect at point (2,5).

Answer: The smallest critical value is -5

Answer:

How do you calculate grams per 100mL concentration?

The concentration is the amount divided by the volume it is dissolved in. For example you might dissolve 0.9g of sodium chloride in 100mL of water. Sometimes this is referred to as 0.9% w/v since it is 0.9g weight divided by 100mL volume and “w/v” stands for weight per volume.”

Solubility≡62.5⋅g⋅100⋅mL−1..

Explanation:

☯We want Concentration=Mass of solute100 mL volume of solvent.

We make the reasonable assumption that the volume of solution is equal to 40⋅mL.

And so we set up the quotient.

25⋅g(40100)⋅mL=

☯In order to answer this question, you'll want to make use of the fact that pure water under standard conditions has a density of 1 g/ml. This means that 50 ml of pure water would have a mass of 50 grams. Therefore, we know that our sample has a 25 grams of sugar, in order for the total mass to be 75 grams.

☯The question doesn't specify what unit of concentration they prefer, so you can use the easiest, which is (mass of solute)/(volume of solvent) which in this case is 25g/50ml or .5 g/ml. If you need to write this in terms of molarity, you can use the molar mass of sugar to convert the 25g into moles and divide by .05 L, as molarity is given by (moles of solute)/(volume of solvent in liters).

☯Sugar solutions or "syrups" are used extensively in canning, and sometimes referred to as "heavy" or "light" syrups.

The terms heavy and light are commonly used in two different ways. We refer to weight when we say that an adult is heavier than a child. On the other hand, something else is alluded to when we say that one syrup is heavier than another. A teaspoon of heavy syrup would obviously weigh less than a gallon of light syrup, but heavy syrup is heavier in the sense that a given volume weighs more than the same volume of light syrup. It's interesting that a given volume of "heavy cream" actually weighs less than "light cream" (in this case, "heavy" refers to the thickness, or percent milk fat).

In "Molecular Gastronomy", Herve This (pronounced Thees) points out[2] that more precision is needed in canning recipes. Some call a heavy syrup 1 cup sugar to 2 cups water (a ratio of 0.5:1) while others refer to a medium syrup as 3-1/4 c sugar to 5 c water (a ratio of 0.65:1). The latter is actually heavier, or denser. Which is better for canning?

So, the slope of the given line is 2.

The slope of a line is a measure of the steepness of the line and is represented by the letter "m" in the equation of a line: y = mx + b. The slope is calculated by the ratio of the change in y to the change in x.

The equation of a line y = 2x - 10 is already in the slope-intercept form, y = mx + b, where m is the slope and b is the y-intercept.

In this case, the slope of the line is m = 2.

This means that for every unit increase in x, y will increase by 2 units. If we graph this line, we can see that it has a steepness of 2, which means it has a positive slope. A positive slope indicates that the line increases as we move to the right and a negative slope indicates that the line decreases as we move to the right.

Answer:

∠ BAS = 122° , ∠ N = 89°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

(2)

∠ BAS is an exterior angle of the triangle, then

19x + 8 = 6x + 11 + 75

19x + 8 = 6x + 86 ( subtract 6x from both sides )

13x + 8 = 86 ( subtract 8 from both sides )

13x = 78 ( divide both sides by 13 )

x = 6

Then

∠ BAS = 19x + 8 = 19(6) + 8 = 114 + 8 = 122°

--------------------------------------------------------------

(4)

11x + 31 is an exterior angle of the triangle , so

11x + 31 = 5x - 4 + 10x - 1

11x + 31 = 15x - 5 ( subtract 15x from both sides )

- 4x + 31 = - 5 ( subtract 31 from both sides )

- 4x = - 36 ( divide both sides by - 4 )

x = 9

Then

∠ N = 10x - 1 = 10(9) - 1 = 90 - 1 = 89°

Answer: 20.15

Factorization of algebraic expressions is defined as the process of finding the factors of an expression which refers to finding two or more expressions whose product is equals to that expression. Some Identities which are used to Factorize Algebraic Expressions,

(a+b)² = a² + b² + 2ab

(a - b)² = a² + b² - 2ab

a² - b² = (a+b)(a -b) etc.

We need to factorise, p(x) = x² − 36.

The algebraic expression, p(x) can be factorised by using property, a² - b² = (a+b)(a-b). So, it can be written as x² - 6², comparing it with a² - b² , here a = x,

b = 6. Hence, (x² − 36) = (x+6)(x−6). Therefore, the required factors are (x+6)(x−6).
