Answer:

.66 are in each bag.

Step-by-step explanation:

14/3 = 4.66666666667

then you grab the answer for 14/3 and divide by 7

this in turn will get you .66 repeated

so .66 of a pound is in each 7 bags.

Answer:

  D: 21

Step-by-step explanation:

The first term is (a1). The third term is (a1)r². The product of these terms is ...

  (a1)(a1)r² = ((a1)r)², the square of the second term.

The missing term is √(7·63) = √441 = 21.

_____

Additional comment

In consideration of the above, you can also see that the common ratio can be found from ...

  a3/a1 = ((a1)r²)/(a1) = r² = 63/7 = 9

Then the common ratio is r = √9 = 3, and the second term is 7·3 = 21.

The average rate of growth of the ice can be found by dividing the thickness by the number of days of growth

The growth rate of the ice over the 8 days is 0.375 inches/day

Reason:

The known information on the ice are;

The time it took the ice to reach a thickness of 3 inches = 8 days

Required:

The (average) rate that the ice is growing in c=inches per day

Solution:

[tex]Rate \ of \ growth \ of \ ice= \dfrac{Increase \ in \ thickness}{ Time} = \dfrac{\Delta \ Thickness}{\Delta T}[/tex]

Therefore;

[tex]Rate \ of \ growth \ of \ ice= \dfrac{3 \ inches}{ 8 \ days} = 0.375 \ inches/day[/tex]

The (average) rate of growth of the ice over the 8 days is 0.375 inches per day

Answer:

look at the explanation 20,440

Step-by-step explanation:

so the invested 2,800 $  and the interest rate is 1.46 so first what I would do is 1.46 times 5 = 7.3 then 7.3 x 2,800 =20,440

so I think the answer is 20,440

not sure if this is correct but I gave it my all

reorder factors of the second side

3-0 / 0 + 6

3/6 = 1/2

then the y intercept is 0,3 so we add 3

y = 1/2x +3

Answer: x= 13, y=24

Step-by-step explanation:

7x - 31 + 63 + 5x - 8 = 180 (sum of co-interior angles)

Solving this we get x = 13

4y + 27 + 5x - 8 = 180 (sum of co-interior angles)

Replacing x=13 and solving, we get y = 24

The value of x is 7 and y is 31.5.

Transversal line is a line that is formed by cutting two or more parallel lines.

Here there are two transversal lines which cut two parallel lines.

If two parallel lines are cut by a transversal line, then the interior angles on the same side of the transversal will be supplementary.

The angles of measures (7x - 31)° and (5x - 8)° + 63 are two interior angles  on the same side of transversal and are thus supplementary.

(7x - 31)° + (5x - 8)° + 63 = 180°

7x + 5x - 31 - 8 + 63 = 180

12x + 24 = 180

12x = 180 - 24

12x = 156

x = 156/12 = 13

Similarly, (5x - 8)° and (4y + 27)° are a pair of interior angles on the same side of transversal.

(5x - 8)° + (4y + 27)° = 180°

5x + 4y + 19 = 180

(5 × 13) + 4y + 19 = 180

65 + 4y + 19 = 180

4y = 96

y = 24

Hence the values of x and y are 13 and 24 respectively.
