Answer:

Hello,

Step-by-step explanation:

using Thalès 's théorem :

\dfrac{x}{x+10} =\dfrac{4}{10} \\\\10x=4x+40 \ (cross\ products)\\\\6x=40\\\\x=\dfrac{20}{3} \ (simplified\ by\ 2)

x≈6.7 (i don't know what d.p. means , perhaps 1 decimal after the point)

Determine the equation of the plane in the form
Bond [772]
A plane parallel to vectors <9, 6, 2> and <-8, -4, -5> is given by
\left|\begin{array}{ccc}x&y&z\\9&6&2\\-8&-4&-5\end{array}\right| =0\\ (-30 + 8)x - (-45 + 16)y + (-36 + 48)z = 0\\-22x+29y+12z=0

Since the plane passes through point (5, -5, 8), then
-22(5) + 29(-5) + 12(8) = -110 - 145 + 96 = -159

The required plane is -22x + 29y + 12z = -159
z = 11/6x - 29/12y - 53/4

A cafeteria serves lemonade that is made from a powdered drink mix. There is a proportional relationship between the number of s
ZanzabumX [31]

Therefore ,the constant of proportionality comes out to be 4 and the equation that represents the relationship is x=1/4y.

<h3>What is equation?</h3>

Since equations are essentially questions, efforts to systematically find answers to those questions have been the driving force behind the development of mathematics. From straightforward algebraic equations that just require addition or multiplication to differential equations, exponential equations that use exponential expressions, and integral equations, there are many different types of equations that range in complexity.

Here,

scoop is represented as x and water is represented as y

therefore, For every 2 scoops of mix, one half gallon of water is needed, and for every 5 scoops of mix, one and one fourth gallons of water are needed.

Equation from the given data is

2x = 1/2y or x=1/4y

and

5x = (1+1/4)y

5x=5/4y

So,

x=1/4y.

Therefore ,the constant of proportionality comes out to be 4

The equation that represents the relationship is x=1/4y.

We can graph the plot by using the given equation x=1/4y

or 4x=y

so for every x value we have to put 4 times its value into y for every point

you point in the graph.

Through (1,-6) parallel to the line x + 2y = 6
MakcuM [25]

Hello!

To find the line parallel to the line x + 2y = 6 and passing through the point (1, -6), we will need to know that if two lines are parallel, then their slopes are equivalent to each other.

Since the given equation is written in standard form, we will need to change it to slope-intercept form to get the slope. Slope-intercept form is: y = mx + b.

x + 2y = 6 (subtract x from both sides)

2y = 6 - x (divide both sides by 2)

y = 6/2 - x/2

y = -1/2x + 3 | The slope of parallel lines are -1/2.

Since we are given the slope, we need to find the y-intercept of the line that goes through the point (1, -6) by substituting that point into a new equation with a slope of m equalling to -1/2.

y = -1/2x + b (substitute the given point)

-6 = -1/2(1) + b (simplify - multiply)

-6 = -1/2 + b (add 1/2 to both sides)

b = -11/2 | The y-intercept of the parallel line is -13/2.

Therefore, the line parallel to x + 2y = 6 and goes through the ordered pair (1, -6) is y = -1/2x + -11/2.

A card is drawn at random from a pack of 52 playing cards. Given that the card is a diamond, find the probability that the card
lesantik [10]

Answer:

1/52

Step-by-step explanation:

There is only one of each type of card in each suit.

P(card is a diamond) = 13/52

P(card is a diamond + king) = (13/52)×(1/13) = (13/676) = (1/52)
