Select the answer that describes the properties of a square.

Answer:

If im not wrong, if every question is 2 points of 100 points in total means that are 50 questions, so if he gets 10 wrong then he would be losing 20 points which his final grade would be 80!

Answer:

Score with 10 questions wrong: 80

Score with x questions wrong: 100−2x

Step-by-step explanation:

each point is deducted by 2 pts and so, with 10 question, he got an 80.

100 is the availability of the points and 2x means which the points were lost

Answer:

21134 bacteria

Step-by-step explanation:

The given parametrs can be interpreted as:

[tex]y = 8(2.4)^t[/tex]

Required

Find y when t = 9

Substitute [tex]t = 9[/tex]

So:

[tex]y = 8(2.4)^9[/tex]

[tex]y = 8 * 2.4^9[/tex]

[tex]y = 8 * 2641.81[/tex]

[tex]y = 21134.48[/tex]

[tex]y = 21134[/tex] --- approximated

Hence, there are 21134 bacteria

Answer:

2x^3

Step-by-step explanation:

The equation that represents this relationship will be y = 2u³.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

The value of y varies directly as the cube of u. y = 54 when u = 3.

y ∝ u³

Removed the proportionality constant and place the equal sign with constant k.

y = ku³

Put y = 54 when u = 3, then the value of k will be

54 = k (3)³

54 = 27k

k = 2

Then the equation that represents this relationship will be

y = 2u³

The equation that represents this relationship will be y = 2u³.

Answer:

A. has a right angle

thats one

Answer:

I think it is A and D. Not 100% sure tho.

Answer:

<1 = 43

<2= 17

<3= 120

<4=60

<5= 60

<6= 60

<7 =17

<8= 120

<9= 43

Step-by-step explanation:

< 4, <5, <6 are all 60

<3 and <4 are a linear pair, so they add to 180. Since <4 is 60, <3 is 180-60= 120

<6 and <8 are a linear pair, so they add to 180. Since <6 is 60, <8 is 180-60= 120

Angles 1 and 9 are congruent

4x+3=9x-47

50=5x

10=x

<1= 4(10)+4= 43

<9-9(10)-47=43

Now you have 2 angles for the triangle A B D- subtract the 2 known from 180

<2= 180-43-120=17

<7= 180-43-120=17

Answer:  A.) A CD has a predetermined time limit before a withdrawal can be made.

Hope this helps :)

A CD has a predetermined time limit before a withdrawal can be made is the statement best describes a characteristic of a CD.

A deposit is the act of placing cash with some entity, most commonly with a financial institution, such as a bank

A CD has a predetermined time limit before a withdrawal can be made.

This is the best statement that describes a characteristic of a CD (certificate of deposit) account.

A CD is a type of savings account that requires the depositor to commit to leaving their funds in the account for a predetermined period of time, called the term or maturity.

During this time, the funds are locked in and the depositor cannot withdraw them without incurring a penalty.

This makes a CD less flexible than a regular savings account but typically offers higher interest rates.

CD accounts do not usually allow for more withdrawals than a money market account, and there are no withdrawal minimums that are less than the account balance.

Hence, A CD has a predetermined time limit before a withdrawal can be made is the statement best describes a characteristic of a CD.

Answer:

566

Step-by-step explanation:

We need to write the following number in standard form.

500 + 60 + 6

Here, the first no is 500, the second number is 60 and the other number is 6.

It can be done as follows :

500 + 60 = 560

And

560 + 6 = 566

So, the standard form is 566 inc which 6 is at one's place, another 6 at tens place and 5 at hundred places.

Answer:

  56 feet

Step-by-step explanation:

Let x represent the height of the pole. Then the distance to the anchor point is (x-23), and the length of the wire is (x+9). The Pythagorean theorem tells you the relation between these values is ...

  (x+9)² = x² +(x -23)²

  0 = x² -64x +448 . . . . . subtract the left side, put in standard form

  0 = (x -8)(x -56) . . . . . . factor

The solutions to the quadratic are x=8 and x=56. For our purposes, we require x > 23 so the distances are positive. That means x=56 is the solution of interest.

The pole is 56 feet tall.

Answer:

5) 10³: So you do 10* 10*10= 1,000

so 10³= 1,000

All you are doing is takeing the number and multiplying itself to the power.

6) (-7)⁴= so you are taking the -7 in parenthesis and making it positive, then you are taking the positive 7 and doing  7⁴. Once you do that you get positive 2401.

8) 3+6* (-5) to the second (i dont have the symbol) so you are going to do PEMDAS: Parenthesis, Expression, Multipulcation, Divison, Addition and Subtraction. so it would be 5+6*25to the second. So you do multipulcation first, so do 6*25=150. Then do addition and do 150+3=153

Step-by-step explanation:

5) 10³= 1,000

6)(-7)⁴= 7⁴= 2401

8)3+6* (-5) to the second= 3+6* (5) to the second= 3+6* 25= 6*25= 150+3= 153

Answer to 8 is= 153

Answer:

x≥0

Step-by-step explanation:

the domain is anything above 0

The domain of the graph is [0, 10] or 0 ≤ x ≤ 10 when the annual growth of the python population from the beginning of 2000 to 2010.

It is defined as a special type of relationship and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have:

Florida Fish and Wildlife is having problems with the growing population of Pythons in the Everglades.

As we can see in the graph the annual growth of the python population from the beginning of 2000 to 2010 is continuously increasing between 0 to 10,

Mathematically,

x ∈ [0, 10] or

0 ≤ x ≤ 10

Thus, the domain of the graph is [0, 10] or 0 ≤ x ≤ 10 when the annual growth of the python population from the beginning of 2000 to 2010.

Answer:

  A.  6

Step-by-step explanation:

The wording "set A and set B" means you're interested in elements that belong only to both. In your diagram, that is Region II. There are 6 elements that belong to A and B.

  AB = 6

_____

Additional comment

"A and B" is also called the "intersection" of the two sets: A ∩ B.

The number you have chosen is the number in Regions I, II, and III. That is the set of elements that belong to A or B. You have identified the "union" of the two sets: A ∪ B. (It might also be represented as A+B.)
