Plz help, I don't need the show all work.
topjm [15]

Answer:

The answer is 108 cm²

Step-by-step explanation:

First, you have to find the height of the parallrelogram using trogonometric formula, sinθ = oppo./hypo. :

oppo. = height

hypo. = 9 cm

θ = 59°

sin 59° = height/9

height = 9 sin 59°

= 7.715 cm (4s.f)

Given that the formula of area of parallelogram is, A = base×height. Then, you can substitute the value into the formula :

base = 14 cm

height = 7.715 cm

A = 14 × 7.715

= 108 cm² (3s.f)

Before the clowns arrived, only 35% of the children wore happy faces. If 117 children did not wear happy faces, how many childre
denis-greek [22]

Answer:

180

Step-by-step explanation:

If 35% did not wear happy faces, then 100% -35% = 65% did wear happy faces.

Then we have ...

... 117 = 65% × (all children)

... 117/0.65 = all children = 180 . . . . . . divide by 65% = 65/100 = 0.65

There were 180 children in all.

The line y =3x-5 meet x-axis at the point M. The line 3y+2x=2 meets y-axis at point N. Find the equation of the line joining M a
Law Incorporation [45]

<u>Answer-</u>

<em>The line equation is,</em>

\boxed{\boxed{6x+15y-10=0}}

<u>Solution-</u>

The line y =3x-5 meets x-axis at the point M, i.e M is the x-intercept of this line. At the x-intercept y=0, so

\Rightarrow 0 =3x-5

\Rightarrow 3x=5

\Rightarrow x=\dfrac{5}{3}

So, coordinate of M is (\dfrac{5}{3},\ 0)

The line 3y+2x=2 meets y-axis at point N, i.e N is the y-intercept of this line. At the y-intercept x=0, so

\Rightarrow 3y+2(0)=2

\Rightarrow 3y=2

\Rightarrow y=\dfrac{2}{3}

So, coordinate of N is (0,\ \dfrac{2}{3})

The line joining M and N can be found out by applying two point formula of straight line,

\Rightarrow \dfrac{y-y_1}{y_2-y_1}=\dfrac{x-x_1}{x_2-x_1}

\Rightarrow \dfrac{y-0}{\frac{2}{3}-0}=\dfrac{x-\frac{5}{3}}{0-\frac{5}{3}}

\Rightarrow \dfrac{y}{\frac{2}{3}}=\dfrac{x-\frac{5}{3}}{-\frac{5}{3}}

\Rightarrow -\dfrac{5}{3}y=\dfrac{2}{3}(x-\frac{5}{3})

\Rightarrow -5y=2(x-\dfrac{5}{3})

\Rightarrow -5y=2x-\dfrac{10}{3}

\Rightarrow 2x+5y-\dfrac{10}{3}=0

As it is given that all the coefficients are integers, so multiplying with 3

\Rightarrow 6x+15y-10=0
