Answer:

I belive its the 6th floor, although i did the mathb in my head.  I apologize if it is incorrect ;-;

Step-by-step explanation:

Answer:

6th floor

Step-by-step explanation:

Starting on the ground floor, we will reference this point as the 0th floor. From there she goes:

down 2 floors (0 - 2) | -2 |

up 5 floors (-2 + 5) | 3 |

down 1 floor (3 - 1) | 2 |

up 3 floors (2 + 3) | 5 |

down 5 floors (5 - 5) | 0 |

and up 6 floors (0 + 6) | 6 |

Therefore... in the end she lands on the 6th floor

Answer:

(x, y ) → (x - 14, y - 20 )

Step-by-step explanation:

A translation of 14 units to the left means subtract 14 from the original x- coordinate.

A translation of 20 units down means subtract 20 from the original y- coordinate.

The translation rule is

(x, y ) → (x - 14, y - 20 )

Answer:

22.5

Step-by-step explanation:

multiply 5 x 7 and add half of 5.

multiply 3 x 7 and add half of 3.

width is 22.5

The width of the enlarged photograph is 22.5 inches.

Scale factor is the ratio defining the relation between the scales of original new objects.

Given that, Cassie has a family photograph that measures 3-inches wide and 5-inches long. She wants to enlarge the photograph and hang it on the wall, and the length of the enlarged photograph is 37.5 inches,

We can conclude that the scale factor is 3/5.

Let the width of the enlarge photograph be x,

Therefore, 3/5 = x/37.5

x = (37.5/5)x3

x = 22.5

Hence, the width is 22.5 inches.

Answer:

600ft^2

Step-by-step explanation:

Because we are rounding the dimensions to the nearest ten this means the length of 29ft because 30ft and the width of 22ft is 20ft

Area = l X w

Area = 30 X 20

Area = 600

Therefore an estimate for the area of the wall is 600ft^2

Answer:

area =length x width

20 is the length and 30 is the width

So, area=20x30

=600ft^2

Answer:

Mean = 1.67

The median = 1

The mode = 1

Step-by-step explanation:

1, 0, 2, 4, 0, 1, 1, 1, 2, 5, 3, 0, 1, 2, 2

Arrange in ascending order (from the lowest to the highest)

0, 0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 4, 5

Mean = sum of all the scores / number of matches

= 0 + 0 + 0 + 1 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 2 + 3 + 4 + 5 / 15

= 25 / 15

= 1.67

Mean = 1.67

Median = The middle score

0, 0, 0, 1, 1, 1, 1, 1, 2, 2, 2, 2, 3, 4, 5

The median score is 1

The mode = score that appears most

= 1

The mode = 1

Score 1 appears 5 times

I got this answer write on my assignment.

Answer:

George has 64 nickel and 32 dimes.

Step-by-step explanation:

Normally, we have:

One nickel = 5 cents

One dime = 10 cents

One dollar = 100 cents

Therefore, total number of cents that George has can be calculated as follows:

Total number of cents = $6.40 * 100 = 640 cents

Based on the above, we have:

640 cents = 640 / 5 = 128 nickel

640 cents = 640 / 10 = 64 dimes

Therefore, we have:

128 nickel = 64 dimes

Divide through by 2 in order to share 640 cents equally, we have:

128 nickel / 2 = 64 dimes / 2 => 64 nickel = 32 dimes

Since 64 minus 32 is equal to 32, it therefore implies that George has 64 nickel and 32 dimes.

Answer:

231.00

Step-by-step explanation:

Carol earns 16 for 30 minutes, so $32 an hour, 32 * 3 = 96.

Peter earns 15 every 20 minutes, so 20 * 3 = 60 minutes, and 15 * 3 = 45,

so he earns 45 dollars an hour. 45 * 3 = 135

135+96 = 231.00

Answer

Option #3

Step-by-step explanation:

Answer:

the third one so C.

Step-by-step explanation:

Answer:

DEC = 90*

Step-by-step explanation:

Ok, well lets list some facts really quick.

Since AB is parallel to CD, and AD is parallel BC, angles A and C are the same, angles B and D are also the same.

Knowing that A and C are the same, C = A, the measurement of angle C is 68*. ( * = degrees)

Since line EC bisects, meaning it splits into two equal parts/measurements, C, the measurement of angle DCE and BCE is both 34*.

How is it 34*, well 68*/2 = 34.

Next, interior angles of triangles on the same line equal to 180* (a straight line).

This means that the measurement of angle B has to equal up to 180* when added with angle A.

To find angle B we do 180* - 68* = 112*.

Thus, angle B equals 112*, because when added with A, it equals 180.

Since angles B and D are the same, angle D is also 112*.

One way to check this is to add up all interior angles in a rectangle (those angles being A, B, C, and D) and they should all add up to 360.

Since line DE bisects angle D, or splits it into two equal parts, angles ADE and CDE equal 56*.

Note: All angles in a triangle add up to 180*.

Since we know angles A and D, we can find angle DEA based on the rule above.

A + ADE + AED = 180*

68 + 56 + AED = 180*

124 + AED = 180

Subtract 124 from both sides to get angle AED

124 + AED = 180

-124              -124

AED = 56*

Now we must find angle CEB.

B + BCE + CEB = 180*

112 + 34 + CEB = 180

146 + CEB = 180*

Subtract 146 from both sides to get CEB

146 + CEB = 180

-146              -146

CEB = 34

Now we can find angle DEC.

AED + CEB + DEC = 180*

56 + 34 + DEC = 180*

90 + DEC = 180*

Subtract 90 from both sides to get DEC

90 + DEC = 180*

-90               -90

DEC = 90*

Answer: DEC = 90*

Answer:

x=-2 and 4

Step-by-step explanation:

First of all, this is not a linear equation, but a quadratic equation which has two answers (or otherwise known as roots, solutions, or zeroes)

We can start by subtracting the 8 on both sides

x^2-2x-8=0

We can factor this, so we take two factors that multiply to -8 and two factors that add to -2

(x-4)(x+2)

Set those equal to zero x-4=0 and x+2=0

So x=-2 and 4

Answer:

Work shown below!

Step-by-step explanation:

[tex]x^{2} -2x=8[/tex]

Subtract 8 from both sides;

[tex]x^{2} -2x-8=0\\(x+2)(x-4)=0[/tex]

x + 2 = 0

Subtract 2 from both sides;

x = -2

x - 4 = 0

Add 4 to both sides;

x = 4

Answer:

Each candy bar cost 4 dollars.

Step-by-step explanation:

First,

31-3 = 28

Next,

28/7 = 4

Therefore, each candy bar cost 4 dollars.

Answer:

So, the coefficient of x8 in the given expansion will be 210.

Step-by-step explanation:

We know,

General term in (x+a)n is given by,

Tr+1=C(n,r)xn−rar

∴ General term in (x2−1x)10 ,

Tr+1=C(10,r)(x2)10−r(−1x)r

⇒Tr+1=(−1)rC(10,r)x20−2rx−r

Now, we have to find the term having coefficient x8.

∴20−2r−r=8⇒r=4

So, T5 will have coefficient x8.

∴T5=(−1)4C(10,4)x8

⇒T5=10⋅9⋅8⋅74⋅3⋅2⋅1x8

⇒T5=210x8

Answer:

f(x)=3x-2

g(x)=x^2

(g o f)(3)=?

(g o f)(3)=g(f(3))

x=3→f(3)=3(3)-2

f(3)=9-2

f(3)=7

(g o f)(3)=g(f(3))=g(7)

x=7→g(7)=7^2

g(7)=49

Answer: (g o f)(3)=49

OR,if you like this answer can also work

For this case, the first thing we must do is the composition of functions.

We have:

f (x) = 3x-2

g (x) = x ^ 2

(gOf) (x) = (3x-2) ^ 2

We now evaluate the function:

(gOf) (3) = (3 * (3) -2) ^ 2

(gOf) (3) = (9-2) ^ 2

(gOf) (3) = (7) ^ 2

(gOf) (3) = 49

Answer:

(gOf) (3) = 49

Both are same

Answer:

La densidad del líquido desconocido es de aproximadamente 0,6855 g/ml.

Step-by-step explanation:

Los parámetros dados son;

La masa del recipiente vacío = 38,52 g

La masa total del recipiente cuando está lleno de agua = 137,26 g

La masa total del recipiente cuando se llena con el líquido desconocido = 106.21 g

Por lo tanto;

La masa del agua = La masa total del recipiente cuando está lleno de agua - La masa del recipiente vacío

La masa del agua = 137,26 g - 38,52 g = 98,74 g

La masa del líquido desconocido = 106,21 g - 38,52 g = 67,69 g

La gravedad específica del líquido desconocido = (La densidad de la sustancia desconocida) / (La densidad del agua)

De lo que tenemos;

La gravedad específica del líquido desconocido = (La masa del líquido desconocido) / (La masa de un volumen igual de agua)

∴ La gravedad específica del líquido desconocido = (67,69 g) / (98,74 g) ≈ 0,6855

De la ecuación, gravedad específica = (La densidad del líquido desconocido) / (La densidad del agua) y la densidad del agua = 1 g / ml, tenemos;

gravedad específica ≈ 0.6855 = (La densidad del líquido desconocido) / (1 g / ml)

La densidad del líquido desconocido ≈ 0.6855 × 1 g / ml ≈ 0.6855 g / ml

La densidad del líquido desconocido ≈ 0,6855 g / ml.

Answer:

$166.07

Step-by-step explanation:

You have to convert 6% into a decimal which is .06

Then multiply the original price by that decimal that you just got. So 156.67x.06=9.4002 (don't round)

Then add the original price with that number you just got which is your tax. In other words 9.4002+156.67= 166.0702 (so now you round to get 166.07) :))
