A marching band needs to raise $13,500 for a trip to the Rose Bowl. The director told the band members that one-third of the amount that has been raised so far is equal to half of the amount that is still needed. How much more money needs to be raised for the trip?
Answer: $5400
Step-by-step explanation:
x = amount raised so far
13500 - x = amt. still needed
x/3 = (13500 - x)/2
2x = 3(13500 - x)
2x = 40500 - 3x
5x = 40500
x = 40500/5 = 8100 (amt. raised so far)
13500 - 8100 = 5400 (amt. still needed)
"How do we transform System A into System B?
Equation [A1] → Equation [B1]
Equation [A2]→ Equation [B2]
Equation [A1]+Equation [A 2] → Equation [B 2]
Equation [A2]+ Equation [A 1] → Equation [B 1]"
The transformation of System A into System B is:
Equation [A2]+ Equation [A 1] → Equation [B 1]"
The correct answer choice is option D
How can we transform system A into System B ?To transform System A into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].
System A:
-3x + 4y = -23 [A1]
7x - 2y = -5 [A2]
Multiply equation [A2] by 2
14x - 4y = -10
Add the equation to equation [A1]
14x - 4y = -10
-3x + 4y = -23 [A1]
11x = -33 [B1]
Multiply equation [A2] by 1
7x - 2y = -5 ....[B2]
So therefore, it can be deduced from the step by step explanation above that System A is ultimately transformed into System B as 1 × Equation [A2] + Equation [A1]→ Equation [B1] and 1 × Equation [A2] → Equation [B2].

The vertex angle of an isosceles triangle measures
15 degrees more than one of its base angles. How
many degrees are there in a base angle of the
triangle?
The required three angle is 55 , 55 and 70
What is an angle ?
An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.
When two straight lines or rays intersect at a single endpoint, an angle is created. The vertex of an angle is the location where two points come together. The Latin word "angulus," which means "corner," is where the term "angle" originates.
Let each of the base angle of isosceles triangle = x
Vertex angle = (x+15)
Sum of the angle = 180
x + x + (x + 15) = 180
3x + 15 = 180
3x = 180 - 15
x = 165 / 3
x = 55
Each base angel = 55
Vertex angle = x + 15
= 55 + 15
= 70
Required three angles = 55 , 55 and 70

Find the Maclaurin series of the following functions. Step by Step Please
The Maclaurin series of xcos(-x) up to n = 3 is

The function is given in the question as
m(x) = xcos(-x)
Taylor (Maclaurin) series of xcos(x) up to n=5
A Maclaurin series is given by f(x),

We need to do to get the desired polynomial is to calculate the derivatives, evaluate them at the given point, and plug the results into the given formula.
f⁽⁰⁾(x) = f(x) = xcos(x)
Evaluate the function at the point: f(0)=0
1st derivative: f(1)(x)=(f(0)(x))′=(xcos(x))′=−xsin(x)+cos(x)
1st derivative at the given point: (f(0))′=1
2nd derivative: f(2)(x)=(f(1)(x))′=(−xsin(x)+cos(x))′=−xcos(x)−2sin(x)
Evaluate the 2nd derivative at the given point: (f(0))′′=0
3rd derivative: f(3)(x)=(f(2)(x))′=(−xcos(x)−2sin(x))′=xsin(x)−3cos(x)
Evaluate the 3rd derivative at the given point: (f(0))′′′=−3
Now, use the calculated values to get a polynomial:
[tex]m(x)=0+\frac{1}{1!}x+\frac{0}{2!}x^2+\frac{-3}{3!}x^3+.....[/tex]
[tex]m(x)=x-\frac{1}{2}x^3+\frac{1}{24}x^5-\frac{1}{720}x^7+\frac{1}{40320}x^9+\ldots \:[/tex]

A clothing business finds there is a linear relationship between the number of shirts, n , it can sell and the price, p , it can charge per shirt. In particular, historical data shows that 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $22 . Find a linear equation in the form p(n)=mn+b that gives the price p they can charge for n shirts.
The linear equation in the form p(n) = mn + b that gives the price p they can charge for n shirt is p(n) = - 1 / 250n + 34.
How to linear equation in slope intercept form?Linear equation can be represented in slope intercept form as follows:
y = mx + b
where
m = slopeb = y-interceptTherefore, the clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p , it can charge per shirt. 1,000 shirts can be sold at a price of $30 , while 3,000 shirts can be sold at a price of $22 .
Therefore,
using (1000, 30) and (3000, 22) let's find the slope.
m = 22 - 30 / 3000 - 1000
m = - 8 / 2000
m = - 1 / 250
Hence, let's find the y-intercept using (1000, 30)
p(n) = mn + b
where
p = pricen = number of shirtTherefore,
30 = - 1 / 250 (1000) + b
30 = - 4 + b
b = 30 + 4
b = 34
Hence, the linear equation is p(n) = - 1 / 250n + 34

4 7/8 + (2 1/6). It’s fractions by the way.
Answer:
7 and 1/24
Step-by-step explanation:
4 7/8 + 2 1/6
First when adding fractions, we want to have a common denominator. To do that, we must multiply the fractions until we get a desired denominator. We can find LCM.
The LCM of 6 and 8 is 24, so we must multiply accordingly.
We can put this into improper fraction form:
39/8 + 13/6
Then multiply accordingly. Multiply by 3 on both sides for the first fraction, and multiply by 4 on both sides for the second to get a denominator of 24.
117/24 + 52/24
Now, we can add the fractions.

Find the probability of exactly three
successes in six trials of a binomial
experiment in which the probability of
success is 50%.
The probability exactly three successes in six trials is 31.30%
What is Binomial Distribution?A binomial distribution can be defined as the probability of a success or failure outcome in an experiment or survey that is repeated multiple times.
The probability distribution of a binomial distribution is given by :
P(x = k) = n! /k!(n - k)! P^x(1 - P)^(n - k)
In our case :
n = 6
P = 50/100 = 0.5
Now we want the probability that:
x = 3
This is because the question states that we want the probability that the number of successes are exactly 3.
We do the substitution in the probability distribution function as follows :
P(x = 3) = 6!/3!(6 - 3)! × 0.5³ × (1 - 0.5)³
= 0.3125
= 31.25%
= 31.30%
Hence, the probability of exactly three successes in six trials of a binomial experiment in which the probability of success is 50 is 31.30%

Because we have to multiply 8x12 which is 96. and there is x next to it. so keep the x as it is.
and next to it is minus ( - ) sign so keep it as it is.
now we have to multiply 8x20 which is 160.
so if we write it together it will be:

If 41 and 42 are complementary angles and if the measure of 41 is 50° more than the measure of 42, determine the measures of 41 and 42
Answer:
m∠1 = 70
m∠2 = 20
Step-by-step explanation:
41 and 42 are complementary angles: m∠1 + m∠2 = 90
measure of 41 is 50° more than the measure of 42: m∠1 = m∠2 + 50
substitute: (m∠2 + 50) + m∠2 = 90
simplify and solve: 2(m∠2) + 50 = 90
2(m∠2) = 40
m∠2 = 20
