Answer:

Trapezium

Step-by-step explanation:

quadrilateral are geometrical shapes which have four sides

Different type of quadrilateral are

Rectangle, parallelogram, square , rhombus, kite and trapezium.

It is given that no sides are congruent.

Thus

the figure cannot be Rectangle, parallelogram, square , rhombus

as these shapes have at least one pair of sides congruent.

________________________________________

So, figure can be either kite or trapezium

But kite has no sides parallel.

Thus the shape is trapezium.

Trapezium is a quadrilateral which has one pair parallel sides but they are not same in length.

The other two sides can be congruent or cannot be congruent.

Find x. See attached picture.

pishuonlain [190]

Answer:

B. 22

Step-by-step explanation:

We know tan60=

$\sqrt{3}$

Let common side be x

Tan = opp/adj= sqrt(3)

$\frac{11 \sqrt{6} }{x} = \sqrt{3}$

Transposing we get :

$\frac{11 \sqrt{6} }{ \sqrt{3}} = x = 11 \sqrt{2}$

Now, we know that since the other triangle is a 45-45-90 triangle, we can state that the side adjacent to the given angle = 11 sqrt(2) as the two sides are equal due to the triangle being an isoceles triangle.

Solve for x by using Pythagorean theorem:

$\sqrt((11 \sqrt{2}^{2} + (11 \sqrt{2} )^{2} ) = x$

$= > \sqrt{2(11 \times 11 \times \sqrt{2} \times \sqrt{2}) } = x$

$= > \sqrt{484} = x = 22$

Hence answer is B. 22

9n - 6 = 5n + 18 Solve

IgorLugansk [536]

Answer:

n = 6

Step-by-step explanation:

9n - 6 = 5n + 18

Subtract 5n from each side

9n-5n - 6 = 5n-5n + 18

4n -6 = 18

Add 6 to each side

4n -6+6 = 18+6

4n = 24

Divide each side by 4

4n/4 = 24/4

n = 6

There are 72 boys and 90 girls on the math team for the next math competition Mr. Johnson would like to arrange all the students

yawa3891 [41]

Answer:

Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.

Step-by-step explanation:

Given:

Number of boys = 72

number of girls = 90

We need to arrange students in rows with equal number of only boys and only girls.

To find the maximum number (x) of boys or girls in each row, we will find the GCF (Greatest Common Factor) of the numbers 72 and 90, such that 'x' divides both numbers evenly without a remainder.

Now to find GCF we will factorize both numbers.

$72 = 2\times2\times2\times3\times3$

$90= 2\times 3\times 3\times 5$

from above we can say that;

GCF = $2\times 3\times 3 = 18$

Hence Mr. Johnson can arrange 18 students in each row, that is 4 rows of boys and 5 rows of girls.
