there are 120 students in a school marching band. they march in an array with the same number of students in each row. what are the dimensions of the different arrays that the band can form?
Answer:
20 X 6
Step-by-step explanation:
20 X 6 = 120 I'm not smart but this is pretty easy
sin( X+Y ) = cos( X−Y ) = 1,
find the value of X and Y.
answer x = 225 and y = -135
Step-by-step explanation:
x+y = 90 and x= 90-y and x -y = 360 so 90-y -y = 360
what is the equation of the blue line?
The answer y = 3x-7 / y = 3(x-4)+5 is wrong
Answer:
y = 4x -3
Step-by-step explanation:
Here, we want to get the equation of the blue line
As we can see, the y-intercept is -3
So we have the equation as;
y = mx -3
To get the value of m which is the slope , we check for any point on the line
That would be;
(1,1)
Let us have this substituted;
1 = m(1) - 3
1 = m -3
m = 1 + 3
m = 4
so the equation of the straight line is;
y = 4x -3
What is the area of rectangle RSTU? Show step by step!
Plz help me and solve this ASAP! Solve ASAP! Plz! Thank you!
Step-by-step explanation:
We only know 1 side, and that is the width of 4. We only have the diagonals at our side. Half of the diagonal is 5. As a result, the diagonal is 10. I want you to imagine a triangle that has a base of 4 and a hypotenuse of 10. Use the Pythagorean Theorem to find b, or the height.
a² + b² = c²
4² + b² = 10²
16 + b² = 100
100 - 16 = 84
b² = 84
b = √84
b ≈ 9.165
Now we know the length of the rectangle, which is about 9.165. Multiply that by 4 to get the area.
9.165 * 4
36 + 0.4 + 0.24 + 0.020
36.4 + 0.24 + 0.02
36.64 + 0.02
36.66 u²
The area of rectangle RSTU is about 36.66 units squared.
Find the coordinates on f the point where y-4x=1 crosses the axis
Answer:
The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]
Step-by-step explanation:
Intercepts of a Function
Given a function y=f(x), the intercepts with the x-axis, if any, can be found by solving the equation:
y = f(x) = 0
The intercepts with the y-axis can be found by calculating
f(0)
We are given the function
y - 4x = 1
To find the x-intercepts, set y=0:
0 - 4x = 1
Solving:
[tex]x = -\frac{1}{4}[/tex]
For x=0:
y - 4*0 = 1
y = 1
The coordinates of the intercepts are (0,1) and [tex]\left(-\frac{1}{4},0\right)[/tex]

At a basketball game, 65% were supporting the home team, while 35% were supporting the visiting team. If 882 attending the game supported the visiting team, what was the total number of people at the game
Answer: 2520
Step-by-step explanation:
Given: Number of people supported the visiting team = 882
Let x = Total number of people at the game.
As per given,
35% of x = 882 [35% were supporting the visiting team]
[tex]\Rightarrow\ 0.35x=882\\\\\Rightarrow\ x=\dfrac{882}{0.35}\\\\\Rightarrow\ x= 2520[/tex]
Hence, the total number of people at the game = 2520 .

[tex](f\circ g)(1)=f(\sqrt{1})[/tex] [tex][\because g(x)=\sqrt{x}][/tex]
[tex](f\circ g)(1)=f(1)[/tex]
[tex](f\circ g)(1)=(1)^2-1[/tex] [tex][\because f(x)=x^2-1][/tex]
[tex](f\circ g)(1)=1-1[/tex]
[tex](f\circ g)(1)=0[/tex]
The value of [tex](f\circ g)(1)[/tex] is 0.
Therefore, the correct option is A.
George wants to invest $3,250. American Bank offers a simple interest rate of 4%, while Liberty Savings offers an interest rate of 3.75% compounded annually. How much more in interest will George earn after 8 years if he invests with Liberty Savings rather than American Bank? $4,363.03
Answer:
$4,363.03
i hope i actually get this right because im doing a test right now in math class
Using the interest formulas, it is found that George will earn $158 more in interest if he invests with Liberty Savings rather than American Bank.
Simple Interest:
[tex]E = Pit[/tex]
In which:
P is the principal, which is the amount invested.i is the interest rate, as a decimal.t is the time, in years.For American Bank, we have that [tex]P = 3250, r = 0.04, t = 8[/tex], hence:
[tex]E = Pit = 3250(0.04)(8) = 1040[/tex]
Compound interest:
[tex]E = P[(1 + r)^t - 1][/tex]
For Liberty Savings, we have that [tex]r = 0.0375[/tex], hence:
[tex]E = P[(1 + r)^t - 1] = 3250[(1.04)^8 - 1] = 1198[/tex]
1198 - 1040 = 158.
He will earn $158 more in interest if he invests with Liberty Savings rather than American Bank.

An angle measures 16° more than the measure of its supplementary angle. What is the measure of each angle?
Answer:
the surface are of a rectangle box of 5cm long, 3cm wide and 4cm wide is 94cm²
The measure of two supplementary angles are 82° and 98°.
What are supplementary angles?Supplementary angles refer to the pair of angles that always sum up to 180°. These two angles are called supplements of each other.
Given that, an angle measures 16° more than the measure of its supplementary angle.
Let the measure of one angle be x.
Then, the other angle is x+16°.
Now, x+x+16°=180°
2x+16°=180°
2x=164°
x=82°
So, x+16°=82+16°=98°
Therefore, the measure of two supplementary angles are 82° and 98°.

325 Towers/(6.25 thousands customers) = 52 Towers/(Thousand customer)
For 3), we have;
377 Towers/(7.25 thousands customers) = 52 Towers/(Thousand customer)
For 4), we have;
481 Towers/(9.25 thousands customers) = 52 Towers/(Thousand customer)
Therefore, the ratios of towers to customers (thousands) all have the same equivalent unit rate of 52 Towers/(thousand customers).

Step-by-step explanation:
To find the first 3 terms, substitute n = 1, 2, 3 into the n th term formula
3(1)² = 3 × 1 = 3
3(2)² = 3 × 4 = 12
3(3)² = 3 × 9 = 27
The first 3 terms are 3, 12, 27

Who walks faster if hichman walks 84 feet in 7 seconds or Brittany who walks 110 feet in 20 Second
Answer:
Hichman will walk faster.
Step-by-step explanation:
Hichman walks 84 feet in 7 seconds and Brittany walks 110 feet in 20 Second.
We need to say who walks faster.
For Hichman,
Distance, d = 84 feet and time, t = 7 s
Speed,
[tex]v_H=\dfrac{d}{t}\\\\v_H=\dfrac{84}{7}\\\\=12\ ft/s[/tex]
For Brittany,
Distance, d = 110 feet and time, t = 20 s
Speed,
[tex]v_B=\dfrac{d}{t}\\\\v_B=\dfrac{110}{20}\\\\=5.5\ ft/s[/tex]
It can be seen that speed of Hichman is 12 ft/s and the speed of Brittany is 5.5 ft/s. It is clear that the speed of Hichman is more than that of Brittany. Hence, Hichman will walk faster.
A person invests 9000 dollars in a bank. The bank pays 4.75% interest compounded quarterly. To the nearest tenth of a year, how long must the person leave the money in the bank until it reaches 12600 dollars?
A=P(1+nr)nt
Answer:
The time required to get a total amount of $ 12,600.00 from compound interest on a principal of $9000 at an interest rate of 4.75% per year and compounded 4 times per year is 7.1 years.
Step-by-step explanation:
Given
Principle P = 9000 dollars
Rate r = 4.75% = 0.0475
Total Amount A = 12600 dollars
compounded quarterly n = 4
To determine:
Time t = ?
Using the equation
[tex]A\:=\:P\left(1\:+\:\frac{r}{n}\right)^{nt}[/tex]
solving the equation for 't'
t = ln(A/P) / n[ln(1 + r/n)]
t = ln(12,600.00/9,000.00) / ( 4 × [ln(1 + 0.011875/4)] )
t = 7.1 years
Therefore, the time required to get a total amount of $ 12,600.00 from compound interest on a principal of $9000 at an interest rate of 4.75% per year and compounded 4 times per year is 7.1 years.
