A / b = c

Multiply both sides by b

A = bc

Divide both sides by c

A / c = b

Answer:

-9 feet

Step-by-step explanation:

The turtle was already at -2 feet below sea level, then the turtle went 7 more feet down. Which means that -2 +7 = -9

Answer:

He started climbing 9 feet up into the tree, so we can assume that the initial position is 9ft above the ground.

Then if he wants to get back into the ground, he must "descend" or climb down 9 ft again.

Then the integer is -9 (because he is climbing down now).

In this case, the 0 represents that he does not move.

So the integer 0 is related to: +0ft or -0ft

This means that he climbs up 0ft or down -0ft, which is the same as not moving at all.

Answer:

  122 = 2(2w +w)

Step-by-step explanation:

If we let w represent the width of the rectangle, then 2w is the length of it. The perimeter is twice the sum of length and width.

  P = 2(L+W)

  122 = 2(2w +w) . . . . an equation for the description

Answer:

The correct option is C

Step-by-step explanation:

Generally

       [tex]MS_B[/tex] stand for Mean Square Between which the mean calculated based on the difference between the sample means

While

 [tex]MS_W[/tex] stands for Mean Square Within which the mean calculated based on the difference between the elements within the set(group)

   Thus  

The [tex]MS_B[/tex]  measures the differences related to the treatment given to each sample. The [tex]MS_W[/tex]  measures the differences related to entries within the same sample.

Answer:

a)0.09176

b)0.22065

c)0.62551

Step-by-step explanation:

a) p(x>21) = p(z> (21-17)/3)=p(z>1.333) = 1-.90824= 0.09176 (subtracting from one because we are looking at the right side of the graph from the Z-table)

b)p(x<15) = p(z< (15-17)/3)=p(z<-.6667) = 0.22065

c)p(16 < x < 25)= (z(16-17)/3 < p < z(25-17)/3)= z(-.333) < p < z(2.667)=.99621 -.37070 = 0.62551

Answer:

[tex]k=4[/tex]

Step-by-step explanation:

So we have the equation:

[tex]\sqrt{2k^2+17}-x=0[/tex]

Where:

[tex]k>0\text{ and } x=7[/tex]

And we want to find k.

Firstly, let's substitute 7 for x. So:

[tex]\sqrt{2k^2+17}-7=0[/tex]

Now, we can solve for k. Add 7 to both sides:

[tex]\sqrt{2k^2+17}=7[/tex]

Square both sides:

[tex]2k^2+17=49[/tex]

Subtract 17 from both sides:

[tex]2k^2=32[/tex]

Divide both sides by 2:

[tex]k^2=16[/tex]

Take the square root of both sides:

[tex]k=\pm\sqrt{16}[/tex]

Evaluate:

[tex]k=\pm 4[/tex]

Remember that we are told k>0. In other words, k must be positive. So, we can ignore the negative answer, giving us:

[tex]k=4[/tex]

So, the value of k is 4.

And we're done!

$612

Step-by-step explanation:

2/13 of 3978 is 612

Answer:

  - 250

Step-by-step explanation:

Pick two points along the line of the graph

(4,7000) and (8,6000)

Using the slope formula

m = (y2-y1)/(x2-x1)

    = (6000-7000)/(8-4)

    -1000/4

   - 250

Answer:

-250

Step-by-step explanation:

Answer:

In ∆ABD and ∆ACD

<BAD =<CAD ( each are half of <A )

<D=<D ( each equal to 90°)

AD = AD ( common)

So ∆ ABD is congruent to ∆ ACD.

Then AB =AC (by C.P.C.T)

Hence,∆ABC is an iso - sceles triangle.

Answer:

r = 8

Step-by-step explanation:

Solve for r:

r + 4 = 12

Subtract 4 from both sides:

r + (4 - 4) = 12 - 4

4 - 4 = 0:

r = 12 - 4

12 - 4 = 8:

Answer: r = 8

The general form of the number is 28,700. The correct option is A.

Any value between 1.0 and 10.0 that can be expressed as a decimal number and multiplied by a power of 10 is referred to as being in standard form.

The given number is 2.87 x 10⁴. The general form of the number can be written as:-

2.87 x 10⁴ = 2.87 x 10000

2.87 x 10⁴  = 28700

Multiply 2.87 by 10000 we will get the general form 28700 for the number.

Therefore, the general form of the number is 28,700. The correct option is A.

Step-by-step explanation:

This is the answer because:

1) 50 and 1 equal to 51

2) The fraction forms of a decimal number is: the decimal number/the decimal number place value

3) Therefore, the answer is 50 + 1 + [tex]\frac{2}{10}[/tex] + [tex]\frac{4}{100}[/tex] + [tex]\frac{2}{1,000}[/tex]

Answer:

2 years

Step-by-step explanation:

If you have $9000 in the saving account, and you take $500, you are left with:

$9000 - $500 = $8500

in one year you will have 3% more of the 8500 which is:

8500/100*3 = $255

so in one year the number on your savings account is:

8500 + 255 = $8755

and by the next year you will have 3% more of the 8755 which is:

8755/100*3 = $262.65

so in two years the number on your savings account is:

8755 + 262.65 = $9017.65

which is a little bit more than the $9000.

so it will take 2 years until the calance again reaches $9000
