two sides of a parallelogram meet at an angle of 50 degrees. If the length of one side is 3 meters and the length of the other s
Anon25 [30]

Answer:

The longer diagonal has a length of 7.3 meters.

The angles are 31.65° and 18.35°

Step-by-step explanation:

If one angle of the parallelogram is 50°, another angle is also 50° and the other two angles are the supplement of this angle. so the other three angles are:

50°, 130° and 130°.

The longer diagonal will be the one opposite to the bigger angle (130°), and this diagonal divides the parallelogram in two triangles.

Using the law of cosines in one of these two triangles, we have:

diagonal^2 = a^2 + b^2 - 2ab*cos(130\°)

diagonal^2 = 3^2 + 5^2 - 2*3*5*(-0.6428)

diagonal^2 = 53.284

diagonal = 7.3\ meters

So the longer diagonal has a length of 7.3 meters.

To find the angles that this diagonal forms with the sides, we can use the law of sines:

a / sin(A) = b/sin(B)

5 / sin(A) = diagonal / sin(130)

sin(A) = 5 * sin(130) / 7.3

sin(A) = 0.5247

A = 31.65\°

The other angle is B = 50 - 31.65 = 18.35°

Help this is really hars

We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope

1. On the last 5 quizzes, Marco has earned a total of 21 out of 25 possible points. If he has a perfect
Nonamiya [84]

The number of points Marco needs to bring his average up to 90% is 15points.

If there's a possible 25 possible points, and Marco has taken 5 quizzes;

Evidently, each quiz has weighs 5 points.

Mathematically;

\frac{21 + 5x}{5(5 + x)}  \times 100\% =  \frac{90}{100}

  • 2100 + 500x = 2250 + 450x

  • 50x = 150

x = 3.

Therefore, he needs 5x points = 15 points to bring his average up to 90%.

Suppose that you have a bowl of 500 m&m candies, and each day you eat 1/4 of the candies you have. Is the number of candies
Aleks [24]

Answer:

500(.75)^{n}

Step-by-step explanation:

It is changing exponentially because if you are eating a fraction of the left over m & m's, that is a different amount each time so it can't be linear.

500(1-(1/4))^n

500(.75)^{n}

Multiply each of the following(2x - 3y) and (x + 5y)​
Vikki [24]

Answer:

2 {x}^{2}  + 7xy - 15 {y}^{2}

Step-by-step explanation:

We can use the rainbow expansion method to find the expression.

(2x - 3y)(x + 5y) \\  = 2 {x}^{2}  + 10xy - 3xy - 15 {y}^{2}  \\  = 2 {x}^{2}  + 7xy - 15 {y}^{2}
