Answer:

r = 6cm

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

36 pi = pi r^2

Divide each side by pi

36 pi/pi = pi r^2/ pi

36 = r^2

Take the square root of each side

sqrt(36) = sqrt(r^2)

6 =r

The radius is 6 cm

r = 6cm

Answer:

radius, r = 6cm

Step-by-step explanation:

$Area = 36 \pi \\\\\pi r^2 = 36 \pi\\r^2 = 36\\r = \sqrt{36} = 6 \ cm$

Answer:

(1) IT MAKES IT EASIER TO UNDERSTAND.

(2) IT HELPS TO ARRIVE AT THE POSSIBLE ROOT CAUSE AND OUTCOME.

(3) IT SHOWS RELATIONSHIP BETWEEN FACTORS.

SITUATION IN LIFE

When Determining the Relationship between my height and my weight.

BMI=WEIGHT/HEIGHT*HEIGHT.

BMI is the dependent variable

Weight and height are independent variables.

Step-by-step explanation: Mathematical representation of data or information is a very important strategy applied to solve certain Complex problems.

Mathematical representation helps to make Complex data or information easily understood,it helps one to derive the possible root cause and outcomes of problems,it also shows Relationship between various treatments or variables or drugs applied in solving problems example in treatment of Diseases.

BMI(BODY MASS INDEX) is a life situation where I have used Mathematical representation to solve, it used to show how your height and weight is related.

Independent variables are variables that do not cause any changes t other variables when altered.

Dependent variables are variables which can cause change in a situation when altered.

In this case BMI depends on The weight and height of a person, while the Weight and height of a person are independent on the BMI.

Answer:

23 cards.

Step-by-step explanation:

After Monday, Esteban has 12 cards.

After Tuesday, Esteban has 12 + 24 = 36 cards.

He gave to his sister x cards.

36 - x = 13

36 = 13 + x

23 = x

Sorry Guys, Angle 12 & 10 are effectively corresponding angles, but angle 10 & 7 are alternate interior angles. Anyways,

Irina-Kira [14]

Answer:

Step-by-step explanation:Angle 12 & 10 are effectively corresponding angles, but angle 10 & 7 are alternate interior angles. Anyways, Angle 12 & 10 are congruent and 10 & 7 are congruent. At the end, the three angles 12, 10, and 7 have the same measure. If we put it otherwise, the line B is intersecting line D which form right angles equals to 90 degrees, so angle 12 = 90, and the same happens with angle 10 and 7, so the three angles are congruent, but at the same time, angle 7 is supplementary with angle 12 because their sum is equal to 180, (90 + 90 = 180). If you think from different angles is hard to choose the right answer, so what I guess is that we don't need to take into account the angle 10, just the fact that line A intersect line C, and Line B intersect line D forming right angles, and that angle 7 and 12 are right angles which sum equals 180, therefore, we could say that they are supplementary angles, but also congruent because they measure the same, so at the end,

Explain how you can use place-value patterns to describe how 50 and 5000 compare
