Answer:

D

Step-by-step explanation:

When we divide the entire equation by -1/2 to get rid of the coefficient of n we get n = 16.

Answer:

D.) 16

Step-by-step explanation:

Solve for n:

-n/2 = -8

Multiply both sides of -n/2 = -8 by -2:

(-2 (-n))/2 = -2 (-8)

-2×(-1)/2 = (-2 (-1))/2:

(-2 (-1))/2 n = -2 (-8)

(-2)/2 = (2 (-1))/2 = -1:

--1 n = -2 (-8)

(-1)^2 = 1:

n = -2 (-8)

-2 (-8) = 16:

Answer: n = 16

Pleaseeeeeeee I need help nowwwww
Tanya [424]

Answer:

(2)

Step-by-step explanation:

One property of a parallelogram is

• opposite angles are congruent, hence

∠L = ∠N and ∠M = ∠P

Using ∠L = ∠N, then

8x - 41 = 6x + 3 ( subtract 6x from both sides )

2x - 41 = 3 ( add 41 to both sides )

2x = 44 ( divide both sides by 2 )

x = 22

-------------

∠M = 2x + 1 = (2 × 22) + 1 = 44 + 1 = 45°

∠P = ∠M = 45° → (2)

Given a geometric sequence in the table below, create the explicit formula and list any restrictions to the domain.
weeeeeb [17]

Answer:

B

Step-by-step explanation:

given the first 3 terms of the geometric sequence - 4, 20, - 100

with r = \frac{-100}{20} = \frac{20}{-4} = - 5

the n th term formula ( explicit formula ) is

a_{n} = a_{1} r^{n-1}

here r = - 5 and a_{1} = - 4, hence

a_{n} = - 4 (-5)^{n-1} with n ≥ 1

40 divided by 6 using integer division
Nitella [24]

Answer: 40 divided by 6 is equal to 6 with a remainder of 4: 40 / 6 = 6 R.

Step-by-step explanation:Start by setting it up with the divisor 6 on the left side and the dividend 40 on the right side like this:

           

   6 ⟌ 4 0  

The divisor (6) goes into the first digit of the dividend (4), 0 time(s). Therefore, put 0 on top:

       0    

   6 ⟌ 4 0  

Multiply the divisor by the result in the previous step (6 x 0 = 0) and write that answer below the dividend.

       0    

   6 ⟌ 4 0  

       0    

Subtract the result in the previous step from the first digit of the dividend (4 - 0 = 4) and write the answer below.

       0    

   6 ⟌ 4 0  

     - 0    

       4    

Move down the 2nd digit of the dividend (0) like this:

       0    

   6 ⟌ 4 0  

     - 0    

       4 0  

The divisor (6) goes into the bottom number (40), 6 time(s). Therefore, put 6 on top:

       0 6  

   6 ⟌ 4 0  

     - 0    

       4 0  

Multiply the divisor by the result in the previous step (6 x 6 = 36) and write that answer at the bottom:

       0 6  

   6 ⟌ 4 0  

     - 0    

       4 0  

      3 6  

Subtract the result in the previous step from the number written above it. (40 - 36 = 4) and write the answer at the bottom.

       0 6  

   6 ⟌ 4 0  

     - 0    

       4 0  

     - 3 6  

         4  

You are done, because there are no more digits to move down from the dividend. The answer is the top number and the remainder is the bottom number. Therefore, the answer to 40 divided by 6 calculated using Long Division is: 6

A rectangle swimming pool was 9 meters wide with an area of 90 square meters. What is the length of the pool?
telo118 [61]

Answer:

10 meters.

Step-by-step explanation:

The area of a rectangle formula is width multiplied by length. So, to find the length of the pool, simply divide the width from the area.

90/9=10

The length of the pool is 10 meters.

Hope this helps!

If not, I am sorry.
