Answer:
720cm^3
Step-by-step explanation:
The volume of the pyramid with a = 9cm, b = 15cm and l = 32cm is 720cm^3.
Answer:
720³ cm
The formula for volume is...
length ×width ×heightWith that information, we should multiply the smaller numbers first.
[tex]B = \frac{1}{2} xy[/tex]
Replace the substituted parameters with 9 and 15, then multiply them and solve.[tex]B = \frac{1}{2}(9)(15) = \frac{135}{2}[/tex]
UseV for volume.[tex]V = \frac{1}{3} * \frac{135}{2} * 32 = 45 * 16[/tex]
Reducing the expression ↓[tex]V = 720^3~cm[/tex]
Hence, the volume is 720³ cm

Check the picture below.
so the deck is a 72x52 rectangular area, and the pool is simply two semicircles with a rectangle, as you see in the picture, we can put both semi-circles and make one circle with their area, so both together are really the area of a circle whose diameter is 29, and thus its radius is half that or 14.5.
Now, the area Belvedere is going to seal is really the "shaded" or bricked area, if we take the area of the whole deck, including the pool, and then get the area of the pool and subtract it from that of the deck's, what's leftover, is the area that wasn't subtracted, namely the "shaded" area.

What is the mean of the data set?
{2, 5, 1, 7, 6, 4, 3}
Enter your answer in the box.
Your answer is 4.
Explanation:--
The Mean of the Data set is ---
2+5+1+7+6+4+3
7
= 4.
Hence, Mean of the data set is 4.
Answer:
To find the mean, you must add all the numbers and divide it by the amount of numbers in the set.
2 + 5 + 1 + 7 + 6 + 4 + 3
= 28
28 divided by 7 = 4
The answer is 4
Step-by-step explanation:
The arithmetic mean is the simple average, or sum of a series of numbers divided by the count of that series of numbers.
In the world of finance, the arithmetic mean is not usually an appropriate method for calculating an average, especially when a single outlier can skew the mean by a large amount.
Other averages used more commonly in finance include the geometric and harmonic mean.

Charlene has a monthly salary = $3,410.
Charlene has a net income that is 7% of her monthly salary.
The computation of the new net income is shown below
= Monthly salary × net income percentage - reduced amount of net income per month
= $3,410 × 7% - $125
= $113.70
Hence, the corrected net income is $113.70

The linear system with two variables is used to find the price. The price of each game is $60 and the price of each controller is $30.
What is the linear system?A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more than two variables.
A customer at a video game store pays $420 for 6 games and 2 controllers.
A second customer pays $180 less than the first customer for 2 games and 4 controllers.
The price of each game is the same, and the price of each controller is the same.
Let x be the price of games and y be the price of the controller. Then the equations will be
6x + 2y = 420 ...1
2x + 4y = 240 ...2
By solving the equations 1 and 2, then we have

the graph shows the number of servings in different amounts of frozen yogurt listed on a carton. Enter an equation that gives the number of servings y in x pints. Use only decimal form, if necessary.
Answer:y=2.5x
Step-by-step explanation:
We have been given a graph that shows numbers of servings (y) in different amounts (x) of frozen yogurt listed on a carton.
To write an equation that gives the number of servings y in x pints, we will have to find the slope (rate of change) of our given linear function.
Since we know that rate of change of a function can be found by vertical change of the function divided by horizontal change of the function.
m= Slope (rate of change).
=Difference between two y-coordinates.
=Difference between corresponding x-coordinates of the y-coordinates.
Upon substituting coordinates of two points (0,0) and (4,10) in slope formula we will get,
The slope of our given line is 2.5.
Now we will write equation of our given line is slope-intercept form. The equation of a line in slope-intercept form is: , where m=slope and b = y-intercept (initial value).
Upon substituting m=2.5 and coordinates of point (4,10) in slope-intercept form of equation we will get,
Upon substituting m=2.5 and b=0 in slope-intercept form of equation we will get,
Therefore, the equation will give the number of servings y in x pints.

3/4(x + 8) = 9 <== convert the fraction to a decimal
0.75(x + 8) = 9 <== distribute
0.75x + 6 = 9 <== subtract 6 from both sides
- 6 - 6
0.75x = 3 <== divide both sides by 0.75 to isolate the variable

A county in north carolina spans 532 square miles. the population density of deer in the county is 11 deer per square mile. how many deer live in the county? round to the nearest whole number, if necessary. 48 deer 68 deer 5,852 deer 5,992 deer
Answer:
C
Step-by-step explanation:
The total population of Deer's in the given span area is 5852 Deer's.
What is population density?Population density is defined as the total number of humans presence
per unit square miles. Mathematically, we can write -
Population density = (Total human population)/(Total span area)
Given is that a county in north Carolina spans 532 square miles. the population density of deer in the county is 11 deer per square mile
We can write the total population of Deer's in the given span area as -
Population = Deer's population density x total area span
Population = 11 x 532
Population = 5852
Therefore, the total population of Deer's in the given span area is 5852 Deer's.
