The total number of the drummers Brady will see in the parade will be 180 and in each band there are 15 drummers.
What will be the number of drummers?We know that Brady went to a big parade and saw 12 different marching bands. If each band had an average of 120 members and 1/8 of them were drummers.
Here each band has 120 members.
1/8 th of the 120 members are drummers So
[tex]\rm Number \ \ the\ Drummers\ in \ each\ Band=\dfrac{120}{8}=15[/tex]
So total number of the drummers in 12 bands will be
[tex]\rm Total=15\times 12=180[/tex]

The air temperature of a town was 22 degrees. It decreased by 12.5 percent. What was the new
temperature?
Answer:
19.25 degrees
Step-by-step explanation:
original temperature = 22 degrees
decreased percentage = 12.5 percents
the new temperature = 22 - (22×[12.5÷100])
=22 - (137.5÷50)
=22 - 2.75

Write the eq in cylindrical coordinates 7x^2-5x 7y^2 z^2=3
The equation 7x² - 5x + 7y² + z² = 3 in the cylindrical coordinate system is 7r² - 5r cos θ + z² = 3.
What is the cylindrical coordinate?In the cylindrical coordinate system, cylindrical dimensions are ordered triples that describe the location of a point.

Several students made comments about this image.
A triangle has angles B, C, D. The exterior angle to angle B is A.
Which comment is true?
“If I know the measures of A and B, I can subtract those measures from 180 to find the measures of the other two angles.”
“If I know the measure of C, I can find the measure of angle A because they are the same.”
“If I know the measures of angles C and B, I can find the measures of A and D.”
“If I know the measure of angle A, I can find the measure of angle D by subtracting from 180
Answer:
The third comment is the true one: "If I know the measures of angles C and B, I can find the measures of A and D."
This is because you can use the angle B to find angle A by subtracting it from 180, and you can find angle D by adding together C and B and subtracting that from 180.
I hope this helps!
Step-by-step explanation:
From the diagram shown, find the measurement of the indicated angle.
Answer:
x = 50°
Step-by-step explanation:
The three angles of any triangle always add up to 180°. Here, we have a 40° and a right angle. Right angles are always 90°.
To find the value of x, find the sum of the two other angles.
90 + 40 = 130°
Since we know that all angles add to 180, we can conclude the following:
x + 130 = 180
x = 50°

Working together jerry and Skyler determine the circumference was approximately 295.3 feet.
Kyle measured the height to be about 40 feet.
Then the volume of the cylinder will be
Volume = πr²h
Then the value of r will be
We know the circumference. Then the radius will be
295.3 = 2πr
r = 47 ft

A quarterback throws a football with a velocity of 42 mph and a direction of 172°. The wind on the field is 13 mph with a direction of 345°. What are the true speed and direction of the football? Round the speed to the thousandths place and the direction to the nearest degree.
The true speed and direction of the football thrown by the quarterback is 39.139 mph and 7⁰ respectively.
How to find the Relative velocity of the football?The true speed and direction of the football is determined by applying the concept of relative velocity.
Vr/w = Vb - Vw
where;
Vr/w is the velocity of the football with respect to the wind
Vb is the velocity of the football
Vw is the velocity of the wind
Vr/w = 42 mph - 13 mph = 29 mph
The direction speed can be determined by a triangle
Direction of the speed, θ = (360 - 345) - (180 - 172)
θ = 15 - 8 = 7⁰
Resultant speed;
[tex]R^2 = 42^2 + 13^2 - 2(42 \times 13 \times cos7)\\\\R^2 =849.139\\R = \sqrt{849.139}\\R = 29.139 mph[/tex]
Thus, the true speed and direction of the football thrown by the quarterback is 39.139 mph and 7⁰ respectively.

Galvin and Henry spend a certain amount of money from their money box each month to buy plants. The table (function 1) shows the relationship between the amount of money (y) remaining in Galvin’s money box and the number of months (x): Number of Months (x) Amount Remaining (in $) (y) 1 80 2 75 3 70 4 65 The equation (function 2) shows the relationship between the amount of money, y, remaining in Henry’s money box and the number of months, x: Function 2 y = −7x + 80 Which statement explains which function shows a greater rate of change? Function 2 shows a greater rate of change, because Henry spends $7 each month and Galvin spends $5 each month. Function 2 shows a greater rate of change, because Henry spends $80 each month and Galvin spends $15 each month. Function 1 shows a greater rate of change, because Galvin spends $15 each month and Henry spends $73 each month. Function 1 shows a greater rate of change, because Galvin spends $5 each month and Henry spends −$7 each month.
Answer:
Function 2 shows a greater rate of change, because Edwin spends $9 each month and Adam spends $7 each month.
I found this out because for Adam, you simply subtract the y-coordinates from each other and get 7 each time. Edwin clearly shows that he Spends $9 each month with the negative sign.
Step-by-step explanation:
Answer:
Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.
Step-by-step explanation:
Function 1
Money remaining in Galvin's money box:
[tex]\begin{tabular}{| c | c |}\cline{1-2} Number of Months (x) & Amount Remaining (in \$) (y)\\\cline{1-2} 1 & 80\\\cline{1-2} 2 & 75 \\\cline{1-2} 3 & 70 \\\cline{1-2} 4 & 65 \\\cline{1-2}\end{tabular}[/tex]
We can calculate the rate of change by using this formula:
[tex]\textsf{rate of change}=\dfrac{\textsf{change in y}}{\textsf{change in x}}[/tex]
[tex]\implies \textsf{rate of change}=\dfrac{75-80}{2-1}=\dfrac{-5}{1}=-5[/tex]
Therefore, The rate of change of function 1 is -5 which means that Galvin spends $5 per month.
Function 2
Money remaining in Henry's money box:
[tex]\sf y = -7x+80[/tex]
This is represented as a linear equation: y = mx + b
(where m is the slope or "rate of change" and b is the y-intercept of "initial value)
Therefore, the rate of change of function 2 is -7 which means that Henry spends $7 per month.
Conclusion
Function 2 shows a greater rate of change, because Henry spends $7 per month and Galvin spends $5 per month.

Step-by-step explanation:
6*3.14 = 18.84

The solution is 62.84 m
The perimeter of the figure is P = 62.84 m
What is a Circle?
A circle is a closed two-dimensional figure in which the set of all the points in the plane is equidistant from a given point called “center”. Every line that passes through the circle forms the line of reflection symmetry. Also, the circle has rotational symmetry around the center for every angle
The perimeter of circle = 2πr
The area of the circle = πr²
where r is the radius of the circle
The standard form of a circle is
( x - h )² + ( y - k )² = r²,
where r is the radius of the circle and (h,k) is the center of the circle
Given data ,
Let the perimeter of the figure be represented as P
Now , the figure has a semi circle , a square and a triangle
The side of the square = 12m
So , the number of sides of square in the perimeter of the figure = 2 sides
So , perimeter of 2 sides = 2 x 12 = 24 m
Now , the 2 sides of the hypotenuse of the right triangle is also part of the figure , so
perimeter of 2 sides of the triangle = 2 x 10 = 20 m
Now , the total perimeter of figure = perimeter of the semi circle + 24 + 20
Perimeter of semi circle = 2πr / 2
The radius of the circle = 6 m
Substituting the value of r in the equation , we get
Perimeter of the semi circle = ( 2 x 3.14 x 6 ) / 2
Perimeter of the semi circle = 18.84 m
So , the perimeter of the figure P = 18.84 m + 24 m + 20 m
The perimeter of the figure P = 62.84 m
Therefore , the value of P is 62.84 m
Hence , The perimeter of the figure is P = 62.84 m
