Given

AB = 36 cm

Find

Side DE

Explanation

here we use mid segment theorem ,

this theorem states that the mid segment connecting the mid points of two sides of a triangle is parallel to the third side of the triangle and the length of the midsegment is half the length of the third side.

so , DE = 1/2 AC

DE = 36/2 = 18 cm

final Answer

therefore , the correct option is c

List the conditions as per question:

Inequality to represent the total number of pieces of sushi is:

A statement which best describes how the reasonable domain compares to the mathematical domain is that: C. the mathematical domain includes all real numbers, while the reasonable domain includes only real numbers greater than 2.

In Mathematics, a domain can be defined as the set of all real numbers for which a particular function is defined. This ultimately implies that, a domain is the set of all possible input numerical values or numbers to a function and the domain of any graph comprises all the input numerical values or numbers which are primarily shown on the x-axis.

Next, we would evaluate the function which represents the perimeter of this rectangle by substituting the value of 2 as follows:

f(w) = 6w – 8

f(2) = 6(2) – 8

f(2) = 12 – 8

f(2) = 4.

For the length of this rectangle, we have:

Length = 2w - 4

Length = 2(2) - 4

Length = 4 - 4

Length = 0

Therefore, the width of this rectangle must be real numbers that are greater than 2.

The answer is option B

The intermediate step in the form (x + a)² = b when you solve the given quadratic equation by using completing the square method is (x + (√3 - 2)/2)² = 77/4.

In Mathematics, the standard form of a quadratic equation is given by:

ax² + bx + c = 0.

In this exercise, you're required to determine the intermediate step in the form (x + a)² = b when you solve the given quadratic equation by using completing the square method. Therefore, we would re-write the quadratic equation by subtracting 19 from both sides as follows:

x² + 6x + 19 = 4x

x² + 6x + 19 - 19 = 4x - 19

x² + 6x = 4x - 19

x² + 6x - 4x = 19

x² + 2x = 19

In order to complete the square, we would have to add (half the coefficient of the x- term)² to both sides of the quadratic equation as follows:

x² + 2x + (1/2)² = 19 + (1/2)²

x² + 2x + 1/4 = 19 + 1/4

(x + (√3 - 2)/2)² = 77/4

The price of the two stocks will be same in 1 hours .

in the question ,

it is given that

the price of the stock A at 9 A.M is $15.21

price increases at the rate of 0.07 each hour .

so the price of the stock A at 12 P.M. is 15.21 + 0.21 = $15.42

and the price of the stock A after x hours from 12 P.M. is given by the equation

stock A = 15.42 + 0.07(x)

the price of stock B at 12 P.M. is $15.96

price decreases at the rate of 0.15 each hour .

the price of the stock B after x hours from 12  P.M. is given by the equation

stock B = 15.96 - 0.15(x)

since the price of the two stocks is same , we equate both the equations .

15.42 + 0.07(x) = 15.96 - 0.15(x)

15.42 + 0.07x = 15.96 - 0.15x

0.15x + 0.07x = 15.42 - 15.21

0.22x = 0.21

x = 0.9545

x ≈ 1

Therefore , The price of the two stocks will be same in 1 hours .

So they all can be considered as statistical questions.

Thus, all the questions in the given list are statistical questions.

1.

If you have to answer the question for most popular lunch choice, you have to collect data of the lunch choices by a large portion of the called population. Then the lunch choice corresponding to highest frequency will be considered as the most popular lunch choice. Since the conclusion is data driven, this is a statistical question.

2.

In order to answer the question, you need to collect the information about the name of school each of the called population is admitted to. If all the students are found to be admitted to the same school, then the name of that school would be the answer.

Here also, the conclusion is data driven, so this is also a statistical question.

3.

To answer this question, you have to gather all the teaching staff of the school, and take individual answers to which subject they teach. The number of teachers who answered math will be the answer for this question.

For Blue Car:

Distance = 33 & 1/2 miles

Gasoline = 1 & 1/4 gallons

For Red Car:

Distance = 22 & 2/5 miles

Gasoline = 4/5 gallon

To determine the rate unit rate for miles per gallon for each car, we use the following formula:

First, we find the unit rate for blue car:

Convert mixed numbers to improper fractions: 33 & 1/2 = 67/2 and 1 & 1/4 = 5/4

Next, we find the unit rate for red car:

Therefore, the car that could travel the greater distance on 1 gallon of gasoline is the red car.

Answer:

Step-by-step explanation:

the area of a rectangle is

length × width.

in our case that is

(7/3 × b + 21) × (3/7 × b) =

= 7/3 × 3/7 × b × b + 21 × 3/7 × b =

= 1 × b² + 3×3 × b = b² + 9b = b(b + 9) ft²

so, the area is

b² + 9b = b(b + 9) ft²

remember, an area is always a square "something".

a volume a cubic "something".

so, when the lengths are given in feet, the areas are square feet or ft².

The gross pay that the employee will get is $276.14.

The job regarding the question pays $14.50 and the person works 24 hours per week. The weekly pay will be:

= 24 × $14.50

= $348

Also, the employer withhold 10% of your gross pay for federal taxes, 7.65% for FICA taxes and 3% for state taxes. Therefore, the gross pay will be:

= Weekly pay - Federal tax - Fica tax - state tax

= $348 - (10% × $348) - (7.65% × $348) - (3% × $348)

= $348 - $34.80 - $26.62 - $10.44
