Shalnov [3]3 years ago
6 0

Answer:

78°

Step-by-step explanation:

This is a isosceles trapezoid which means the the top angles are equal to each other and the bottom angles equal to each other

Also the sum of one bottom angle + top angle = 180 so we can say a + 102 = 180 therefore a = 78°

marin [14]

Answer:

  544

Step-by-step explanation:

The ratios of cartons are ...

  B : P = 2 : 1

  S : L = 2 : 1

  L : B = 2 : 1

Combining these into a single set of ratios, we have ...

  S : L : B : P = 8 : 4 : 2 : 1

Then the proportion of the order that is strawberry is ...

  8/(8+4+2+1) = 8/15

and the number of strawberry cartons is ...

  (8/15)·1020 = 544

The store ordered 544 cartons of strawberry yogurt.

If the exterior angle of a regular polygon is 7.2 degrees, what is the name of that polygon?
kirill [66]

A regular polygon with exterior angle of 7.2 degrees is a 50-gon.

<h3>Regular polygon</h3>

Regular polygon are polygon that are equiangular. This simply means they are polygon with equal angles.

The formula to find the number of sides of a polygon using exterior angle is as follows:

  • exterior angle = 360 / n

where

n = number of sides

Therefore,

7.2 = 360 / n

cross multiply

7.2n = 360

divide both sides by 7.2

n = 360 / 7.2

n = 50

The polygon has 50 sides. Therefore, it is a 50-gon

What ratio is proportional to 18/21
Doss [256]

Answer:

There are many.

Step-by-step explanation:

When you say proportional, you are looking for a ratio that is equivalent to the ratio given. In your case, there are many so you might need to be more specific. But still, we can help you figure it out.

An easy way to do this would be to scale it down to its simplest form and then move upwards. To find proportional ratios, just multiply denominator and the denominator with the same factor.

\dfrac{18}{21} = \dfrac{6}{7}

That is your ratio in its simplest form. Now we can scale up, I'll show you how to do one completely:

\dfrac{6}{7} x \dfrac{2}{2} = \dfrac{12}{14}

That's the same ratio scaled up by a factor of 2.

---------------------------------------------------------------------------------------

\dfrac{6}{7} x \dfrac{3}{3} = \dfrac{18}{21}

That's the ratio given

---------------------------------------------------------------------------------------

\dfrac{6}{7} x \dfrac{4}{4} = \dfrac{24}{28}

Scaled up by a factor of 4

---------------------------------------------------------------------------------------

\dfrac{6}{7} x \dfrac{5}{5} = \dfrac{30}{35}

Scaled up by a factor of 5.

The list goes on and on.
