THE MEASURE OF TWO ADJACENT ANGLES OF THE PARALLELOGRAM ARE IN THE RATIO OF 3:2. FIND THE MEASURE OF EACH OF THE ANGLES OF THE P

BaLLatris [955]

Answer:

The adjacent angles are: 72 and 108

Step-by-step explanation:

Given

Angle Ratio = 3 : 2

Required

Find the measure of each angle

Let the angles be $x\ and\ y.$

Such that:

$x + y = 180$ --- adjacent angles of a parallelogram

and

$x : y = 3 : 2$ --- given

Convert to fraction

$\frac{x}{y} = \frac{3}{2}$

Cross Multiply:

$2x = 3y$

Make x the subject:

$x = \frac{3}{2}y$

$x + y = 180$ becomes

$\frac{3}{2}y + y = 180$

Take LCM

$\frac{3y + 2y}{2}= 180$

$\frac{5y}{2}= 180$

$y = \frac{2}{5} * 180$

$y = 0.4 * 180$

$y = 72$

Recall that:

$x = \frac{3}{2}y$

$x = \frac{3}{2} * 72$

$x = 1.5 * 72$

$x = 108$

Hence, the adjacent angles are: 72 and 108

Which polynomial expression represents the area of the outer most square tile, shown below?

Andrew [12]

ANSWER

${x}^{2} - 6x + 9$

EXPLANATION

The outermost square tile has side length,

$l = x - 3$

The area of a square is given by;

$Area= {l}^{2}$

We substitite the given expression for the side length into the formula to obtain,

$Area= {(x - 3)}^{2}$

$Area= {(x - 3)}(x - 3)$

We expand using the distributive property to obtain;

$Area=x {(x - 3)} - 3(x - 3)$

This gives us:

$Area= {x}^{2} - 3x - 3x + 9$

$Area= {x}^{2} - 6x + 9$

The last choice is correct.

3 cups a b c contain only salt and water the different mixtures are a salt:water 3:22 b Salt 1/8 c salt 12.75% what cup has the

ddd [48]

Answer:

Cup A

Step-by-step explanation:

Cup A

Salt: Water = 3:22

Expressed as a percentage

$\dfrac{3}{22} \times 100 = 13.6\%$

Proportion of Salt =13.6%

Cup B

Salt: Water = 1:8

Expressed as a percentage

$\dfrac{1}{8} \times 100 = 12.5\%$

Proportion of Salt =12.5%

Cup C

Proportion of Salt = 12.75%

Therefore, Cup A has the greatest proportion of salt.
