PLEASE HELP! How do I solve this problem?

The toughest part of this problem could be deciding what names to give the quantities of one-Euro and two-Euro coins.

-- I called the number of one-Euro coins ' N '.
Each of them is worth 1 Euro, so all ' N ' of them are worth ' N ' Euros.

-- I called the number of two-Euro coins ' T '.
Each of them is worth 2 Euros, so all ' T ' of them are worth ' 2T ' Euros.

-- The total number of coins in Penny's pocket is (N + T), and it says there are 11.

-- Their total value is (N + 2T), and it says the total value is 18.

So now you have two equations, with two unknowns.

               N + 2T  =  18
               N +  T  =  11

Subtract the bottom equation from the top one, and you get:

          (N - N) + (2T - T)  =  (18 - 11)

                             T        =      7         (there are 7 two-Euro coins in her pocket)

That right there is the answer to the question, so you don't need to go
any farther.  But if you wanted to, you could also figure out how many
one-Euro coins there are in her pocket.


How many different ways can a director select 4 actors from a group of 20 actors?

Answers

Number of ways = 20C4
Number of ways =  (20 x 19 x 18 x 17) ÷ (4 x 3 x 2 x 1)
Number of ways =  116280  ÷ 24 
Number of ways =  4845.

What is half of an obtuse angle

Answers

Mostly the half of the obtuse angle(if its 180) is a right angle but if its 180 below its an acute angle

Which of these properties of a rigid transformation is exclusive to translations?The measures of the angles and sides in the preimage are preserved.

The points in the preimage lie in the same plane as the points in the image.

All the points in the preimage are shifted the same distance.

The orientation of sequences of points in the preimage are always preserved.

Answers

The properties of a rigid transformation is exclusive to translations is teh phrase "The points in the preimage lie in the same plane as the points in the image". The rest of the statements do not answer the question above.

Answer with explanation:

There are four kind of Rigid transformation that can take place in a two dimensional or Three dimensional geometrical Shape

1. Rotation

2. Reflection

3.Dilation

4. Translation

When we translate a geometrical shape , the Preimage , shifts from one position to another position in  the plane in which it lies ,without changing the shape ,size ,and Interior angle of the PreImage.  

→→I have described first three properties ,which are true to translation by taking a triangle ,having vertices , (0,0), (0,1) and (1,0).

Now, translating the triangle , by 1 unit right and 1 unit up,got the triangle having vertices, (1,1),(1,2) and (2,1).

Option 4 : The orientation of sequences of points in the pre image are always preserved, is the property of a rigid transformation that appears exclusive to translations.

Dwayne is selling hamburgers and cheeseburgers. He has 100 burger buns. Each hamburger sells for $3, and each cheeseburger sells for $3.50. Which system of inequalities represents the number of hamburgers, h, and the number of cheeseburgers, c, he must sell to have sales of at least $80? h + c ≤ 80 3h + 3.5c ≤ 100 h + c ≤ 80 3h + 3.5c ≥ 100 h + c ≤ 100 3h + 3.5c ≤ 80 h + c ≤ 100 3h + 3.5c ≥ 80

Answers

Given:
hamburger = h ; sells for 3
cheeseburger = c ; sells for 3.50
100 burger buns

h + c = 100  

3h + 3.5c > 80  last option.




Answer:

Its D

Step-by-step explanation:

A circular piece of metal has a radius of 3.5 meters. The metal sells for $3.25 per square meter.

What is the total cost of the circular piece of metal?

A.
$11.38

B.
$38.47

C.
$71.44

D.
$125.01

Answers



Use the formula for finding the area of a circle, then multiply it by each square meter.

A = π r²
A = π (3.5)²
A = 12.25π
A = 38.485

C = 3.25(38.485)
C = 125.01

Answer = $125.01
Area of circle = πr²

Radius, r = 3.5m,  

Area = πr² = π*3.5*3.5 = 12.25π m²

Area ≈ 12.25 *3.141 ≈ 38.477 m²

Since the metal sells for $3.25 per square meter.

Total cost  for 38.477 m² = 38.477 * 3.25 = 125.05

Answer is = $125.05

The answer is not really there, but let's say we can manage option D which is $125.01.
