A roll of quarters is shaped like a cylinder and contains 40 each quarter has a thickness of 1.75 and a diameter of 24.26 mm Wha

jarptica [38.1K]

Answer:

D) 32,357mm^3

Step-by-step explanation:

Given

$Quarters = 40$

$Thickness = 1.75mm$

$diameter = 24.26mm$

First, we calculate the volume of 1 roll.

The volume of the cylinder is:

$V = \pi r^2h$

Where

$r = \frac{1}{2} * diameter$

$r = \frac{1}{2} * 24.26mm$

$r = 12.13mm$

And the thickness represents the height.

So:

The volume is:

$V = 3.142 * 12.13^2 * 1.75$

$V = 809.03mm^3$

The volume of the 40 is:

$Roll= 40 * 809.03mm^3$

$Roll=32361.20mm^3$

The closest option is (d):

what are two practical products you could add to find 990 x 37 ; 297 693 2970 6930 69300 6330 29700

VMariaS [17]

First evaluate 990 x 37.
990 x 37 = 36630

Test the given numbers to find the pair that adds up to 36630.
Test 297.
The missing pair will be
36630 - 297 = 36333
Will not work

Test 693.
36630 - 693 = 35937
Will not work

Test 2970.
36630 - 2970 = 33660
Will not work

Test 6930
36630 - 6930 = 29700
This works, because 6930 + 29700 = 36630.

Answer: 6930 and 29700.

On the first day of spring, an entire field of flowering trees blossoms. The population of locusts consuming these flowers rapid

Elza [17]

Answer:

$L(t)=7600e^{0.2273t}$

Step-by-step explanation:

-The locust population grows by a factor and can therefore be modeled by an exponential function of the form:

$P=P_oe^{rt}$

Where:

$P$ is the population after t days.
$P_o$ is the initial population given as 7600
$r$ is the rate of growth
$t$ is time in days

-Given that the growth is by a factor of 5( equivalent to 500%), the r value will be 5

-The population increases by a factor of 5 every 22 days. therefore at any time instance, t will be divided by 22 to get the effective time for calculations.

Hence, the exponential growth function will be expressed as:

$P=P_oe^{rt},\ \ \ P=L(t)\\\\\therefore L(t)=7600e^{5\frac{t}{22}}\\\\=7600e^{0.2273t}$
