The mean for problem 1 is minutes.

The mean for problem 2 is minutes.

Which of the following is a correct inference based on the mean values.

(Enter Only A, B, or C)

Answer:

The correct option is;

R0, 180°

Step-by-step explanation:

The coordinates of ΔXYZ are given as follows;

X(-2, 2), Y(1, 2), Z(0, 4)

The coordinates of ΔX'Y'Z' are given as follows;

X'(2, -2), Y'(-1, -1), Z'(0, -4)

Whereby, the coordinates of the point Y' is (-1, -2), we have the rule that describe the transformation of ΔXYZ to ΔX'Y'Z', given as follows

Coordinates of the preimage = (x, y)

Coordinates of the image = (-x, -y)

Which is in accordance with the transformation by rotation 180° about the origin.

Answer:

$418

$498

Step-by-step explanation:

Jordan has - 3 * $100 = $300,

                     4 * $20 = $80,

                     1 * $ 10 = $10,

                     8 * $1 = $8

Total =              $398

Jordan’s total will be $418 if Jayla gives him one more $20 bill?

Jordan’s total will be $498 if Jayla gives him one more $100 bill?

Jordan's total will be $438 if Jayla gives him one more $20 bill.

Jordan's total will be $498 if Jayla gives him one more $100 bill.

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

If Jayla gives Jordan one more $20 bill, then Jordan will have:

3 x $100 = $300

5 x $20 = $100

1 x $10 = $10

8 x $1 = $8

1 x $20 = $20

Adding these up gives:

$300 + $100 + $10 + $8 + $20 = $438

Jordan's total will be $438 if Jayla gives him one more $20 bill.

If Jayla gives Jordan one more $100 bill instead, then Jordan will have:

4 x $100 = $400

4 x $20 = $80

1 x $10 = $10

8 x $1 = $8

Adding these up gives

$400 + $80 + $10 + $8 = $498

Therefore,

Jordan's total will be $438 if Jayla gives him one more $20 bill.

Jordan's total will be $498 if Jayla gives him one more $100 bill.

Solving steps:

Question: jasmine has all nickels x and dimes y in her coin jar. if she has 36 coins in all, and four more dimes than. nickels find how much money she has in her coin jar

Find: how much money she has in her coin jar

Solution: let's make an equation for this problem

She has 4 more dimes than nikels:y= x+4 Let's use this value for y in the next equation:

she has 18 nickels and 36-18= 18 dimes

The required Jasmine has 16 nickles and 20 dimes which constitute  $2.80 in her coin jar.

Let's use the given information to set up a system of equations to solve for the number of nickels (x) and dimes (y) in Jasmine's coin jar.

We are given that Jasmine has a total of 36 coins in her jar, so we have the equation:

x + y = 36 -- Equation 1

We are also given that Jasmine has four more dimes than nickels, which can be expressed as:

y = x + 4 -- Equation 2

Now, let's solve this system of equations. We can substitute Equation 2 into Equation 1 to eliminate y:

x + (x + 4) = 36

2x = 36 - 4

x = 16

Now that we have the value of x, we can substitute it back into Equation 2 to find y:

y = x + 4

y = 16 + 4

y = 20

Therefore, Jasmine has 16 nickels (x) and 20 dimes (y) in her coin jar.

To find the total amount of money she has, we need to calculate the value of the nickels and dimes separately:

Value of nickels = 0.05 * 16 = $0.80

Value of dimes = 0.10 * 20 = $2.00

The total amount of money in her coin jar is:

$0.80 + $2.00 = $2.80

Jasmine has $2.80 in her coin jar.

Answer:

x =± 4

Step-by-step explanation:

Solve for x:

x^2 - 16 = 0

The left hand side factors into a product with two terms:

(x - 4) (x + 4) = 0

Split into two equations:

x - 4 = 0 or x + 4 = 0

Add 4 to both sides:

x = 4 or x + 4 = 0

Subtract 4 from both sides:

Answer: x =± 4

Answer: (x + 3) / (x - 2)(x - 3)(x - 4)

Step-by-step explanation:

The problem given can be viewed as

a/b over c/d

where a/b is the top fraction and c/d is the bottom fraction.

This can be rearranged to

a × d / b × c

So, you will have:

(x + 4)(x + 3) / (x² - 5x + 6)(x² - 16)

Now, factor the two bottom polynomials so you end up with:

(x + 4)(x + 3) / (x - 2)(x - 3)(x + 4)(x - 4)

Cancel the (x + 4) on the top and bottom so you’re left with the answer:

(x + 3) / (x - 2)(x - 3)(x - 4)

If you need to find the solutions to x, set the denominator equal to zero.

x = 2

x = 3

Answer:

kpm is about 110.02 degrees

Step-by-step explanation:

-kpl and npm are vertical angles, so they're congruent

-npm and lpm are supplementary angles, meaning they add to 180 degrees

we r given:

npm = 14x - 22

lpm = 7x + 4

add these and set equal to 180:

14x - 22 + 7x + 4 = 180

then combine like terms:

21x -18 = 180

isolate the variable by adding 18 on both sides:

21x = 198

divide by 21 on both sides:

x = about 9.43

since kpl and npm r congruent, plug in the value of x in npm (14x-22):

14(9.43)-22

= 110.02

The distance of Saturn from the sun is 9.5 astronomical units.

Orbital period p of a planet and the planet’s distance from the sun, a in astronomical units are related by:

[tex]p = a^{3/2}[/tex]

The orbital period is the time a given astronomical object takes to complete one orbit around the sun.

Given that Saturn's orbital period is 29.5 years.

So, [tex]29.5 = a^{3/2}[/tex]

[tex]a = 29.5^{2/3}[/tex]

a = 9.5 au

Option (2)

Step-by-step explanation:

From the given set of numbers we have to arrange them in the increasing order.

{[tex]\sqrt{72},9.25,\sqrt{83},\pi^2,8.7[/tex]}

Since, [tex]\sqrt{72}=8.49[/tex]

[tex]\sqrt{83}=9.11[/tex]

[tex]\pi ^2[/tex] = 9.87

Therefore, set of numbers will be in the form of,

{8.49, 9.25, 9.11, 9.87, 8.7}

Now arranging these numbers in the increasing order,

8.49 < 8.7 < 9.11 < 9.25 < 9.87

Answer:

-12, -14, -16

Step-by-step explanation:

x + (x+2) + (x+4) = -42

3x + 6 = -42

Isolate the variable 3x by subtracting 6 from both sides

3x = -48

Then isolate the variable x by dividing 3 from both sides

x = -16

Then add 2 for the 2nd number

Then add 4 for the third number

a) 2/7

There are a total of 14 pairs of socks (4+2+8) so 14 is your denominator.

Then you take however many red socks there are and that is your numerator (4).

Then you simplify. 4/14 ; 2/7

b) 1/4

There are a total of 40 headbands (10+6+24) so 40 is your denominator.

Then you take however many red headbands there are and that is your numerator (10).

Then you simplify, 10/40 ; 2/8 ; 1/4

c) 15/28

You then add 2/7 and 1/4.

Given:

Total number of flower they buy = 29 stems

Total cost = $120.94

Lilies cost = $3.42 per stem

Peonies cost = $4.78 per stem

To find:

The number of lily stems and peony stems did they buy.

Solution:

Let number of lily stems = x

Number of lily stems and peony stems = y

According to given information,

[tex]x+y=29[/tex]                           ...(i)

[tex]3.42x+4.78y=120.94[/tex]                ...(ii)

From (i) and (ii), we get

[tex]3.42x+4.78(29-x)=120.94[/tex]

[tex]3.42x+138.62-4.78x=120.94[/tex]

[tex]-1.36x=120.94-138.62[/tex]

[tex]-1.36x=-17.68[/tex]

Divide both sides by -1.36.

[tex]x=\dfrac{-17.68}{-1.36}[/tex]

[tex]x=13[/tex]

Put x=13 in (i).

[tex]13+y=29[/tex]

[tex]y=29-13[/tex]

[tex]y=16[/tex]

Therefore, number of lily stems is 13 and number of lily stems and peony stems is 16.
