Answer:

20 grams will be left.

Step-by-step explanation:

Half-life is 11 days

This means that in each 11 days, you lose 50% of the amount.

33 days

33/11 = 3 half-lifes.

You start with 160 grams

After 11 days: 160/2 = 80 grams

After 22 days: 80/2 = 40 grams

After 33 days: 40/2 = 20 grams.

20 grams will be left.

Answer:

The Answer Is D

Step-by-step explanation:

It kind of self explanatory .

Hillary is the fastest typer and D. Hillary can type 60 words per minute.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Shane can type 275 words in 5 minutes.

So, Shane can type (275/5) = 55 words per minute.

Also given that Hillary can type 240 words in 4 minutes.

So,  Hillary can type (240/4) = 60 words per minute.

Therefore, Hillary is the fastest typer.

Answer:

32 degrees

Step-by-step explanation:

Answer:

32 degrees

Step-by-step explanation:

Answer:

x = 8

Step-by-step explanation:

(6x + 7)° + 45° = (13x - 4)° => exterior angle theorem of a triangle

6x + 7 + 45 = 13x - 4

6x + 52 = 13x - 4

Collect like terms

6x - 13x = -52 - 4

-7x = -56

Divide both sides by -7

x = -56/-7

x = 8

Answer:

3 ft^2

Step-by-step explanation:

first find the width of the storage box using the given volume

V = L * W * H

9 = 4 * W * 3

9 = 12 * W

9/12 = W

W = 3/4 or .75

then with that to find the are of the base multiply the length and the width

a = l * w

a = 4 * 3/4

a = 3

Answer:

my best guess would be B but I am so sorry if its incorrect

well the slope of line would be -1/5

Answer:

  (b)  x = 7, AB = 9, AC = 12

Step-by-step explanation:

ΔAEB ~ ΔCDB so corresponding sides are proportional.

  AB/CB = AE/CD

  (x+2)/(x -4) = 12/4

  x +2 = 3(x -4) . . . . . . multiply by x-4

  x +2 = 3x -12 . . . . . . eliminate parentheses

  14 = 2x . . . . . . . . . . . add 12-x

  7 = x . . . . . . . . . . . . . divide by 2

AB = x +2 = 7 +2 = 9

BC = x -4 = 7 -4 = 3

AC = AB +BC = 9 +3 = 12

__

In summary, ...

  x = 7, AB = 9, AC = 12 . . . . . matches the 2nd choice

Additional comment

Please note the other choices make no sense.

  (a) AB = x +2 = -5 +2 = -3 ≠ -9

  (c) AC = 2x-2 = 2(7) -2 = 12 ≠ 9

Answer:

x-int:(-2,0)(-4,0) . y-int:(0,8)

Step-by-step explanation:

y = x2+6x+8 and y = (x+2)(x+4)

x-int:

x+2=0

x= -2

(-2,0)

x-int:

x+4=0

x=-4

(-4,0)

y-int: plug 0 for x

y=(0+2)(0+4)

y=8

(0,8)

The intercepts of a graph are the points where the graph crosses the x or y axes.

Given that:

[tex]y = x^2 + 6x + 8[/tex]

[tex]y = (x + 2)(x + 4)[/tex]

The x-intercepts

This is when [tex]y = 0[/tex]

So, we have:

[tex]y = (x + 2)(x + 4)[/tex]

[tex](x + 2)(x + 4) = 0[/tex]

Split

[tex](x + 2) = 0[/tex] or [tex](x + 4) = 0[/tex]

Solve for x

[tex]x = -2[/tex] or [tex]x = -4[/tex]

Hence, the x-intercepts are: (-2,0) and (-4,0)

The y-intercepts

This is when [tex]x = 0[/tex]

So, we have:

[tex]y = x^2 + 6x + 8[/tex]

Substitute 0 for x

[tex]y = 0^2 + 6 \times 0 + 8[/tex]

[tex]y = 8[/tex]

Hence, the y intercept is (0,8)

Answer:

maybe an 80 or 90

Step-by-step explanation:

Answer:

a = 30

2a = 60

3a = 90

Step-by-step explanation:

3a + 2a + a = 180 ( Sum of angles of a triangle is 180)

6a = 180

a = 180/6

a = 30

2a = 2 x 30 =60

3a = 3 x 30 = 90
