c. Which volume-to-surface-area ratio would be better for an ice cube¡X the lowest possible or the highest possible?

1 answer:

7 0

Answer: You would want to have the highest possible volume to surface area ratio in an ice cube.

When you put ice into your drink, the goal is to have the ice chill your drink. This takes time. Therefore, you would want the ice to slow melt and cool the drink for as long as you can.

If your ice cube is mostly surface area with less volume, it will melts to quickly and water down your drink. If your ice cube has a higher ratio of volume to surface area, it will stay solid longer and chill your drink longer.

In triangle DEF = 18 and m angle F = 45. Find the length of a leg rounded to the to the nearest tenth.

Bezzdna [24]

Hello there!

If DEF = 18, we then use the sin method, or the law of sin.

18 divide by sin90 would be F = sin45 .

We therefore end up with 12.72 but rounded would be 12.7 as 2 is lower than 5, so, it just rounds back down to 7.

Your answer: 12.7

What's is the value of x<br><br> 1.50(x+6)=27

gogolik [260]

The value of X is 12. STEP 1) distribute the 1.50 to the X and 6 to get 1.50x and 9 STEP 2) subtract 9 from 27 to get 18 STEP 3) divide 18 by 1.5 and you get X=12

Suppose that prices of recently sold homes in one neighborhood have a mean of $225,000 with a standard deviation of $6700. Using

elena55 [62]

Answer:

$211600 = 225000 -k*6700$

$k = \frac{225000-211600}{6700}= 2$

$238400 = 225000 +k*6700$

$k = \frac{238400-225000}{6700}= 2$

So then the % expected would be:

$1- \frac{1}{2^2}= 1- 0.25 =0.75$

So then the answer would be 75%

Step-by-step explanation:

For this case we have the following info given:

$\mu = 225000$ represent the true mean

$\sigma =6700$ represent the true deviation

And for this case we want to find the minimum percentage of sold homes between $211,600 and $238,400.

From the chebysev theorem we know that we have $1 -\frac{1}{k^2}$ % of values within $\mu \pm k\sigma$ if we use this formula and the limit given we have:

$211600 = 225000 -k*6700$

$k = \frac{225000-211600}{6700}= 2$

$238400 = 225000 +k*6700$

$k = \frac{238400-225000}{6700}= 2$

So then the % expected would be:

$1- \frac{1}{2^2}= 1- 0.25 =0.75$

So then the answer would be 75%

Jose has determined he needs to have $800,000 for retirement in 30 years. His account earns 6% interest.

bija089 [108]

A. $285,714.29/360 = $793.65
B. $285,714.29
C. $800,000-285,714.29 = $514,285.71

A. P/T(12)
B. P = A/(1+RT)
C. I = PRT or I = A-P

Answer:
P = $285,714.29

Equation:
P = A / (1 + rt)

Calculation:
First, converting R percent to r a decimal
r = R/100 = 6%/100 = 0.06 per year.

Solving our equation:
P = 800000 / ( 1 + (0.06 × 30)) = 285714.28571429
P = $285,714.29

The principal investment required to get a total amount, principal plus interest, of $800,000.00 from simple interest at a rate of 6% per year for 30 years is $285,714.29.
