Step-by-step explanation:

these look easy you can probably just type it into a calculator, just show your work.

not sure where you got 20 from on the first problem it should be 9/12 I think, based on the examples at the top of the page.

1. 9/12

2. 16/22

3. 30/36

4. 28/44

5. 45/55

6. 50/60

The "/" indicates division btw and or fraction

then do the #x#x#x#x# thing you were doing

Answer: d) 43.1 in³ per apple

<u>Step-by-step explanation:</u>

$A: \dfrac{20\times 13\times 12\ in^3}{72\ apples}\div \dfrac{72}{72}=\large\boxed{43.3\ in^3\ per\ apple}\\\\\\B: \dfrac{12\times 12\times 12\ in^3}{40\ apples}\div \dfrac{40}{40}=\large\boxed{43.2\ in^3\ per\ apple}\\\\\\C: \dfrac{20\times 10\times 6\ in^3}{28\ apples}\div \dfrac{28}{28}=\large\boxed{42.9\ in^3\ per\ apple}$

The average of the rates above is:

$\dfrac{43.3+43.2+42.9}{3}=\large\boxed{43.1\ in^3\ per\ apple}$

Melanie made a circular necklace. She puts beads evenly spaced around the necklace. If the 4th bead is directly across from the

Norma-Jean [14]

If the 4th lies opposite the 11th, then you know the 3rd lies opposite the 10th, the 2nd opposite the 9th, and the 1st opposite the 8th; meanwhile, in the reverse direction you'd find that the 5th lies opposite the 12th, the 6th opposite the 13th, and the 7th opposite the 14th. Move up one more bead and you're back at the 1st, which you already know lies opposite the 8th. Therefore there are 14 total beads.

a quantity with an initial value of 5900 decays exponentially at a rate of 0.85% every 7 years. what is the value of the quantit

laila [671]

The value of the quantity after 99 months is 5228.58.

Given that, an initial value = 5900, rate of decay = 0.85% and time period = 7 years.

<h3>What is the exponential decay?</h3>

The quantity decreases slowly after which the rate of change and the rate of growth decreases over a period of time rapidly. This decrease in growth is calculated by using the exponential decay formula.

The exponential decay formula formula is $Amount=Initial\ value(1-\frac{r}{100} )^{\frac{t}{n} }$

Here, the value $=5900(1-\frac{0.85}{100} )^{\frac{99}{7} }$

= 5900× $(0.9915)^{14.14}$

= 5900×0.8862

= 5228.58

Therefore, the value of the quantity after 99 months is 5228.58.
