Answer:

40.8 minutes

Step-by-step explanation:

Element X decays radioactively with a half life of 8 minutes. If there are 480 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 14 grams?

The formula to find how long it would take which is the time elapsed is given as:

t = t½ × In(Nt/No)/-In2

t = ?

t½ = 8 minutes

Nt = Amount after the time of decay = 14 grams

No = Original Amount of substances = 480 grams

t = 8 × In(14/480)/-In2

t = 40.796285388407 minutes

Approximately to the nearest tenth = 40.8 minutes

Therefore, it would take the element X, 40.8 minutes to decay to 14 grams

Answer:

C is the answer

Step-by-step explanation:

 because if you move the triangle two to the right then X=1

X=1 means the line is up and down going thought x=1

and if that line you make you reflect across it would be C

Answer:

b = 37 degrees

Step-by-step explanation:

all of the angles on a triangle added up equal 180 degrees

111 degrees

32 degrees

111 + 32 = 143

180 - 143 = 37

b angle = 37 degrees

Answer: 37 degrees.

Step-by-step explanation: a triangles degrees all add up to 180 so 111+32=143 and 180-143=37 so 37 degrees.

Answer:

5 to 3

Step-by-step explanation:

The desired outcomes are 4 or red.

Here are all the possible outcomes:

1 red

1 red

1 red

2 green

3 blue

3 blue

4 yellow

4 yellow

The desired outcomes are in boldface. There are 5 desired outcomes.

There are 3 outcomes that are not desired.

odds of 4 or red = 5 to 3

Answer:15 ft

Step-by-step explanation:

Given

The total perimeter needed is [tex]40\ ft[/tex]

The available width of the room is [tex]w=5\ ft[/tex]

Suppose l is the length of the room

So, the perimeter of a rectangle-shaped room is [tex]2(l+w)[/tex]

Putting values

[tex]\Rightarrow 40=2(l+5)\\\Rightarrow l+5=20\\\Rightarrow l=15\ ft[/tex]

Answer:

d=13

Step-by-step explanation:

step 1) combine like terms

8d-3d-12=53

5d-12=53

isolate d

5d-12+12=53+12

5d=65

d=13

Answer:

C

Step-by-step explanation:

Hello There!

x = # of cars and y = # of vans

the total amount of vehicles is 12 so

x + y = 12

each car can hold 4 students and each van can carry 12 students

there are a total amount of 72 students

so 4x + 12y = 72

so from the given information we can conclude that the answer is C

Answer:

c=10

Step-by-step explanation:

Hope it helps. Doing all your questions that you send XD

Answer:

10

Step-by-step explanation:

using the pythagorean theory the missing side would be [tex]c^{2}[/tex] bs its the hypotenuse so

[tex]a^{2} + b^{2} = c^{2}[/tex]

[tex]8^{2} + 6^{2} = c^{2}[/tex]

[tex]64 + 36 = c^{2}[/tex]

[tex]100 = c^{2}[/tex]

and the square root of 100 is 10, which makes your equation

[tex]c = 10[/tex]

Answer:

$8.75

Step-by-step explanation:

STEP TO TAKE TO DETERMINE THE ANSWER

Multiply 13/4 pounds by the cost of one pound of peanut. To do this, convert 13/4 to an improper fraction and then multiply it by $5

[tex]1\frac{3}{4}[/tex] = [tex]\frac{7}{4}[/tex]

[tex]\frac{7}{4}[/tex] × 5 = [tex]\frac{35}{4}[/tex] = [tex]8\frac{3}{4}[/tex] = $8.75

Answer:

the missing side value is 6.7.

Step-by-step explanation:

so the Pythagorean theorem is a^2+b^2=c^2, but since we are missing the b slide the equation now is 7^2-2^2=b^2. now you may not understand why we are missing the b side. so in the Pythagorean theorem, the a and b slides dont really matter, as long as the c side is the hypotenuse, or the longest slide in a triangle. so 7squared is 49, 2 squared is 4, so 49-4= 45, but its 45squared because the equation is c^2-a^2=b^2 so now we know that 45 is b squared, we just have to square root 45, to get about 6.7.
