A specific brand of gourmet chocolate candy contains 7.00 gg of dietary fat in each 22.7-gg piece. How many kilograms of dietary
Oduvanchick [21]

Answer:

635599482kg

Step-by-step explanation:

A gourmet chocolate candy has 7.00 gg of dietary fat in each 22.7-gg piece

for the 22.7 piece , the gg is 7 x 22.7  = 158.9gg in total

1gg = 2204622.6218488 lbs

158.9gg in total  = 158.9 x 2204622.6218488 = 350314534.612

for the box of 4.00 lblb of candy

it is 350314534.612 x 4 = 1401258138.45lb

since our answer is needed in kilograms we convert 1401258138.45lb to kilograms

1lb = 0.453592kg

1401258138.45lb =  1401258138.45lb x 0.453592kg = 635599481.513 ≈ 635599482kg

Algebra 1<br> Help<br> Thank You!!!!!<br> A<br> B<br> C<br> D
andreyandreev [35.5K]

The area of a square is A=s² (s being the side). Since you know this, you can write an equation.

A=(6a - 2b)²

Expanding this would give you,

A=(6a - 2b)(6a - 2b)

Then to solve this you would want to FOIL (Multiply first terms, multiply outer terms, multiply inner terms, multiply last terms)

36a² - 12ab - 12ab + 4b²

Then combine like terms,

36a² -24ab + 4b²

So the answer would be D

Are the lines x – 2y = 4 and y = 2x – 2 <br><br> a. perpendicular<br> b. parallel<br> c. or neither
Alex

Answer:

C

Step-by-step explanation:

x - 2y = 4

-2y = -x + 4

y = 1/2x - 2

y = 2x - 2

Almost perpendixular but not quite. Parallel lines must have the same slope. Therefore, it's neither

Find a recursive formula for the sequence:
SVETLANKA909090 [29]

Answer:

  a_n=-2a_{n-1}+1

Step-by-step explanation:

Successive terms do not have a common difference or ratio, so the sequence is not arithmetic or geometric. We can get a clue as to its nature a couple of places:

  1. from the alternating signs, says there is a negative multiplier involved
  2. from the answer choices

It is helpful to look at the differences of terms:

  -5-3 = -8

  11 -(-5) = 16

  -21-11 = -32

These have a common ratio of -2, so match an exponential form with a ratio of -2 (the last answer choice). Trying that choice with n=1, 2, 3, 4 gives ...

  a[1] = 3

  a[2] = -2(3) +1 = -5

  a[3] = -2(-5) +1 = 11

  a[4] = -2(11) +1 = -21

These match the given sequence, so the appropriate recursive formula is ...

  \boxed{a_n=-2a_{n-1}+1}
