Find the area of a triangle with points (-8,8) , (10,-2), and (-8,-8)

Answer:

the answer is x= 3/4 I think

The value of 'x' that would make Line segment T V is parallel to Line segment Q S is 10. Option C

It is important to note that for line TV to be parallel to line QS, the sides of the triangle must be divided equally.

Thus, we have

RT/TQ = RV/VS

RT = x + 10

TQ = x - 3

RV = x + 10

VS = x

Substitute the value

[tex]\frac{x + 4}{x-3} = \frac{x + 10}{x}[/tex]
Cross multiply

(x+ 4) × x = (x + 10) × (x-3)

x² + 4x =  x² -3x + 10x -30

Divide through by x²

4x = -3x + 10x - 30

Collect like terms

4x + 3x - 10x = - 30

-3x = -30

x = -30/ -3

x = 10

Thus, the value of 'x' that would make Line segment T V is parallel to Line segment Q S is 10 Option C

Since there are no patterns for the rate of change of the function, it is quadratic.

The average rate of change of a function is given by the change in the output of the function divided by the change in the input.

When this rate is constant, the function is said to be linear, while if the rate increases in a proportional way, the function is exponential.

In this problem, no patterns of linearity or of exponentiality can be established, hence the function is quadratic.

Answer:

2nd option

Step-by-step explanation:

the quadrilateral has 1 pair of parallel sides and is therefore a trapezoid.

• each lower base angle is supplementary to the upper base angle on the same side, that is

∠ 1 + ∠ 2 = 180° , so

x + x + 50 = 180

2x + 50 = 180 ( subtract 50 from both sides )

2x = 130 ( divide both sides by 2 )

x = 65

then

∠ 1 = x = 65°

∠ 2 = x + 50 = 65 + 50 = 115°

The probability of picking a red counter is therefore; 8/25.

Since the ratio of red to green is 2 :3 and there are 24 green counters, it follows that the number of red counters is;

x = (2/3)× 24 = 16 red.

The total of red and green is; 16 +24 = 40 which constitutes 80% of the total counters.

The total number of counters is therefore; 40/0.8 = 50 counters.

The probability of picking a red counter is therefore; 16/50 = 8/25.

Proportion is used to show how quantities and amounts are related to each other. The amount that quantities change in relation to each other is governed by proportion rules.

A direct and inverse proportion are used to show how the quantities and amount are related to each other. They are also mentioned as directly proportional or inversely proportional. The symbol used to denote the proportionality is ‘∝‘.  For example, if we say, a is proportional to b, then it is represented as “a ∝ b” and if we say, a is inversely proportional to b, then it is denoted as ‘a∝1/b’

The given question is the example of direct variation.

Powder volume ∝ Liquid volume

∴ We can apply cross multiplication method

Let powder volume be x

1g→ 10ml

x→ 9.6ml

cross multiplying

1 x 9.6 = 10 x [tex]x[/tex]

x = 0.96 g

Answer: Probability = 44%

Step-by-step explanation:

To find the probability of finding 2 black balls in a row, we first need to find the probability of finding 1 black ball at a time.

To do that, we need to divide the amount of total black balls by the number of total balls.

Black balls = 6

Total balls = 3 + 6 = 9

6 divided by 9 = 0.(6)

If you multiply 0,(6) by 100%, it will give you 66% (rounded) of getting a black ball.

Now, to find the chances of getting 2 black balls in a row, we need to multiply [tex]\frac{6}{9}[/tex] by [tex]\frac{6}{9}[/tex]. What we are doing is squaring the chances of getting one black ball, by the number of times we want to get it.

That is equal to 0,(4)

Multiply 0,(4) by 100%, and it will give you 44%(rounded) chances to get a black ball 2 times in a row.

Probability = 44%

Answer :

Step-by-step explanation:

To find the value of 'a' we will use the tangent-chord theorem,

"Angle formed by the chord and a tangent to the circle measure the half of the intercepted minor arc"

Angle 'a' is formed between the chord and the tangent.

Measure of the intercepted arc = (2 × 52)°

Therefore, measure of the angle 'a' = \frac{104}{2}

2

104

a = 52°

Therefore, Option (A) will be the correct option.

Both sides of the equation are not equal, therefore, Massa was wrong.

For an equation to be correct, the values on both sides of the equation must be equal and balance.

Given the expression, 540 ÷ 6 = 9, 540 divided by 6 is 90. 90 is not equal to 9.

f = 0.12 - 0.016 - 0.072 = 0.032

Tambien las diagonales deben dar 0.12, entonces:

0.064 + c + 0.016 = 0.12

c = 0.12 - 0.016 - 0.064 = 0.04

The given quadrilateral is a rectangle because 2 pairs of sides are equal in length.

We are given the coordinates of the quadrilateral as;

W(0, 5), X(-3, 2), Y(0, -4), Z(3, 2).

Now, the formula for distance between two coordinates is;

d = √[(x₂ - x₁)² + (y₂ - y₁)²]

Thus;

WX = √[(-3 - 0)² + (2 - 5)²]

WX = 3√2

XY = √[(0 + 3)² + (-4 - 2)²]

XY = 3√5

YZ = √[(2 + 4)² + (3 - 0)²]

YZ = 3√5

ZW = √[(0 - 3)² + (2 - 5)²]
