If 14 g of a radioactive substance are present initially and 3 yr later only 7 g​ remain, how much of the substance will be present after 6 ​yr?

Answers

Answer 1
It would be 48 bc if you add it all up and subtract it and add again and multiply and divide and multiply within a and the substance of present after 6 yr you will see that i have wasted your time and that is not the answer

Solve the system.
x + y - 3z = -20
-3y + 2z = 5
z = 4

Answers

Answer:

x= -9

y= 1

Step-by-step explanation:

-3y+2z=5

(put the value of z in the equation)

-3y+2(4)=5

-3y+8=5

8-5=3y

3=3y

y=3/3

therefore y= 1

x+y-3z=-20

(put the value of y and z in the equation)

x+1-3(4)=-20

x+1-12=-20

x+1= -20+12

x= -8-1

therefore x= -9

Answers

Answer:

x ≈ 17.14

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan35° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{12}{x}[/tex] ( multiply both sides by x )

x × tan35° = 12 ( divide both sides by tan35° )

x = [tex]\frac{12}{tan35}[/tex] ≈ 17.14 ( to the nearest tenth )

Answer:

ans is 128

Step-by-step explanation:

90+90+52+x=360(all sides of triangle is 360)

180+52+x=360

A rectangle has an area of 1008
square feet. Its width is six feet less
than twice the length. Find the
measures of the length and width of
the rectangle.

Answers

9514 1404 393

Answer:

length: 24 ftwidth: 42 ft

Step-by-step explanation:

The area is the product of length and width. If L represents the length, then the width is (2L -6), and the area is ...

  L(2L -6) = 1008

  L² -3L -504 = 0 . . . . . divide by 2, put in standard form

  (L -24)(L +21) = 0 . . . . factor

  L = 24 . . . . makes the first factor zero

  W = 2L -6 = 2(24) -6 = 42

The length of the rectangle is 24 feet; the width is 42 feet.

cost of Ella's lunch.
A.

= 6. Multiply both sides by 2. Ella's lunch cost $12.
B. 2x = 6. Divide both sides by 2. Ella's lunch cost $3.
C. x + 2 = 6. Subtract 2 from both sides. Ella's lunch cost $4.
O D. X-2 = 6. Add 2 to both sides. Ella's lunch cost $8.

Answers

Answer:

D

Step-by-step explanation:

Because it says Klay lunch cost is $2 less than Ella's.

==> Ella's - $2 = Klay's

==> x-2=6

What is the fraction?

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Let the unknown number be x.

Here, 1/3 = x/12

Multiply both the numerator and denominator of 1/3 by 4, we get

4/12

So, 4/12 = x/12

x=12

Therefore, the unknown number is 12.

During a solar eclipse, explain what would an observeron the Moon see on the surface of the Earth? The strength of an acid is affected by the polarity of the bond connected to the acidic hydrogen. The more highly polarized this bond, the more easily the hydrogen is ionized. Electronegative atoms or groups of atoms present in the structure of an acid can act to withdraw electrons and produce additional polarization. Two common groups of acids to which this principle can be applied are oxoacids and carboxylic acids. In the latter group, the length of the hydrocarbon chain in a carboxylic acid has very little effect on acid strength Longer chains may slightly diminish acidity. Bases act as hydrogen ion acceptors because of the unshared electron pass in their structure. Any group present in a base that withdraws electrons makes these electron pairs less available to accept a hydrogen ion. In contrast, any group that can act as an electron donating group such as hydrocarbon groups (usually represented as II) can increase the base strength. Thus, the addition of electronegative atoms or groups of atoms to the structure of a base decreases the base strength and electron donating groups increase base strength. Many common weak bases are derivatives of ammonia, in which H atom(s) of NH_2 are replaced with other groups. Arrange the following oxoacids in order of decreasing acid strength. Rank from strongest to weakest acid. 1. HBrO2. HClO3. HClO24.
