Answer:

Step-by-step explanation:

r=5 ×90/100=4.5 in

h=6×90/100=5.4 in

volume of original cylinder=π×5²×6=150 π≈471.24 in³

volume of new cylinder=π×4.5²×5.4=109.35 π in³≈343.53 in ³

decrease in volume=150 π-109.35 π=40.65π

% decrease=(40.65 π)/150 π×100=4065/150=1355/50=27.1 %

In one town, the number of pounds of sugar consumed per person per year has a mean of 8 pounds and a standard deviation 3 of 20

lesantik [10]

Answer:

c. 1.67 standard deviations above the mean

Step-by-step explanation:

The z-score measures how many standard deviations a score X is from the mean. It is given by the following formula:

$Z = \frac{X - \mu}{\sigma}$

In which $\mu$ is the mean and $\sigma$ is the standard deviation.

A positive z-score means that X is above the mean, and a negative Z-score means that X i below the mean.

In this problem, we have that:

$\mu = 8, \sigma = 3$

Tyler consumed 13 pounds of sugar last year How many standard deviations from the mean is that?

This is Z when X = 13. So

$Z = \frac{X - \mu}{\sigma}$

$Z = \frac{13 - 8}{3}$

$Z = 1.67$

So this is 1.67 standard deviations above the mean.

If LM = 22 and MN = 15, find LN.

Bas_tet [7]

Answer:

LN=37 units

Step-by-step explanation:

In this problem I will assume that M is a point between point L and point N

therefore

LN=LM+MN

substitute the given values

LN=22+15=37 units

Prakash bought a new car at the dealership for $27,000. it is estimated that the value of the car will decrease 7% each year. wh

Dennis_Churaev [7]

The exponential function models the value v of the car after t years is V = 27000 * (0.93)^t

<h3>How to determine the exponential model?</h3>

The given parameters are:

Initial value, a = $27,000

Depreciation rate, r = 7%

The value of the car is then calculated as:

V = a * (1 -r)^t

Substitute known values

V = 27000 * (1 - 7%)^t

Evaluate the difference

V = 27000 * (0.93)^t

Hence, the exponential function models the value v of the car after t years is V = 27000 * (0.93)^t

4/3x + 1/6x = 36 (solve for x please help I have no idea what it is!!!!!!!

ElenaW [278]

Answer:

x = 24

Step-by-step explanation:

$\frac{4}{3}$ x + $\frac{1}{6}$ x = 36

Make the denominator the same by multiplying the first fraction by 2 to make both denominators 6.

$\frac{8}{6}$ x + $\frac{1}{6}$ x = 36

Now we can calculate the numerators and keep the denominators the same.

$\frac{9}{6}$ x = 36

Find x.

$\frac{6}{6}$ x = $\frac{6}{9}$ × 36

x = 24
