Answer:

The number of students not in the marching band is 346.5

Step-by-step explanation:

Given as :

The total number of children that attend a high school = 450

The percentage of students in the marching band = 23 %

Let The number of students not in the marching band = x

Now ,

∵ The percentage of students in the marching band = 23 %

∴ The percentage of students not in the marching band = 100 % - 23 % = 77 %

So, The number of students not in the marching band = 77 % of the total number of students in the school

I.e The number of students not in the marching band = 77 % × 450

Or , The number of students not in the marching band = $\frac{77}{100}$ × 450

∴ The number of students not in the marching band = 346.5

And The number of students in the marching band = 450 - 346.5 = 103.5

Hence The number of students not in the marching band is 346.5 Answer

Olin [163]

Answer:

Area covered by the fences will be 16.1 unit²

Step-by-step explanation:

Let the first parabola is represented by the function f(x) = 6x²

and second parabola by g(x) = x² + 9

point of intersection of the graphs will be determined when f(x) = g(x)

6x² = x² + 9

5x² = 9

x² = 1.8

x = ± 1.34

Now we will find the area between these curves drawn on the graph.

Area = $\int_{-1.34}^{1.34}[f(x)-g(x)]dx=\int_{-1.34}^{1.34}[6x^{2}-(x^{2}+9)]dx$

= $\int_{-1.34}^{1.34}(5x^{2}-9)dx$

= $[\frac{5}{3}x^{3}-9x]_{-1.34}^{1.34}$

= $[\frac{5}{3}(-1.34)^{3}-9(-1.34)-\frac{5}{3}(1.34)^{3}+9(1.34)]$

= $[-4.01+12.06-4.01+12.06]$

= 16.1 unit²

Compare the two statements |-0.45| and | -0.0045|

djyliett [7]

Absolute value means the distance from 0.

|-0.45| =0.45

|-0.0045|=0.0045

0.45>0.0045

|-0.45|>|-0.0045|

raven plans to increase the price of each item in her store up 10%. which of the following sets of step could raven use to find

user100 [1]

To get the price of the new item after an increase of 10% you would have to find 10% of whatever the price is and add it to the original price so for example say the price is $300 you would do 300*0.10(0.10 is 10%) which is 30 and add that to 300 so the new price would be $330
