12. Noah raised $54 to support the animal shelter, which is 60% of his fundraising goal.
a. Write an algebraic equation to represent the situation.
b. What is Noah's fundraising goal?
To represent the situation algebraically, we use the equation 54 = 0.60G, and solving it gives us Noah's fundraising goal of $90.
Let's represent Noah's fundraising goal as G. According to the problem, Noah has raised $54, which is 60% of his goal. This situation can be translated into the algebraic equation:
54 = 0.60GTo find Noah's fundraising goal (G), we can divide both sides of the equation by 0.60:
G = 54 ÷ 0.60G = $90Therefore, Noah's fundraising goal is $90.

Answer:
A) 2x+50
Step-by-step explanation:
First, let's make a variable for each person
Sam = x
Hector = h
Ted = t
Gina = g
We know that Hector has twice the amount hat Sam has so his equation is
h = 2x
We know that Ted has 100 more than Hector so his equation is
t = h + 100
Gina has 50 less than Ted to she has
g = t - 50
Since we need to find out how much Gina has using units of Sam the equation will be
g = 2x + 100 - 50 or simplified g = 2x + 50

Find the equation of the line normal to the curve of y=cos1/3x, where x=pi
Answer:
The equation of the line normal to the curve of y=cos1/3x, where x=pi is y= 2√3 x - 10.38
Step-by-step explanation:
The equation of the normal to the curve is
Y- y1 = - 1/m (x- x1)
Where m is the gradient.
See attached picture for the complete solution.
The equation of the line normal to the curve of y=cos(1/3)x, where x=pi, can be found by taking the negative reciprocal of the derivative of the curve at that point and using the point-slope form of a line.
Explanation:The equation of the line normal to the curve of y=cos(1/3)x at x=pi can be found by taking the negative reciprocal of the derivative of the curve at that point.
The derivative of cos(1/3)x is -sin(1/3)x*(1/3).
At x=pi, the derivative is -sin(pi/3). Taking the negative reciprocal of this gives the slope of the line normal to the curve
So the slope is 1/ tan(pi/3).
Now, we can use the point-slope form of a line to find the equation of the line.
The point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is the point on the line and m is the slope.
Plugging in the values, we get y - cos(pi/3) = (1/tan(pi/3))(x - pi).
Simplifying further will give us the equation of the line normal to the curve at x=pi.
Find the slope of each set of points.
a.) 4, 3 and -3, 4 b.) -2, 0 and (8, -4)
Answer:
1. (4, 3) and (-3, 4) has Slope = -1/7
2.(-2, 0) and (8, -4) has Slope = -2/5
Step-by-step explanation:
If two such points (a,b) and (c,d) are given, then the slope S is given as:
[tex]S = (\frac{d-b}{c-a} )[/tex]
Now here, the given set of points are:
1. (4, 3) and (-3, 4)
Here, the slope S = [tex](\frac{4-3}{-3-4}) = (\frac{1}{-7}) = -(\frac{1}{7})[/tex]
⇒ S = -1/7
1. (-2, 0) and (8, -4)
Here, the slope S = [tex](\frac{-4-0}{8-(-2)}) = (\frac{-4}{10}) = -(\frac{2}{5})[/tex]
⇒ S = -2/5

A graph with a blue line passing through coordinates (0, -4) and (4, -3) and a red line passing through coordinates (0, -1) and (4, -3).
Answer:
Step-by-step explanation:
y = -12x - 1
y = 14x - 4
-12x - 1 = 14x - 4
-1 + 4 = 14x + 12x
3 = 26x
3/26 = x
y = 14x - 4
y = 14(3/26) - 4
y = 42/26 - 4
y = 42/26 - 104/26
y = - 62/26 reduces to - 31/13
solution : x = 3/26 and y = -31/13 or (3/26,-31/13)

A playground is in the shape of a square. If the perimeter of the playground is 40 feet, find the diagonal distance across the park. Leave your answer in radical form
The length of diagonal of park is √200 feet.
Step-by-step explanation:
Given,
Perimeter of square playground = 40 feet
Let,
a be the length of one side.
Perimeter = 4a
[tex]4a=40\\\\a=\frac{40}{4}\\\\a=10[/tex]
Length of one side of square is 10 feet.
A diagonal will form a right triangle, where,
Diagonal = c

PROBABILITY DISTRIBUTIONS?? Do anyone know how to find probabilities??
Probability of more than 3 = 0.25
Solution:
Given table shows the pitches, frequency and probability of pitches.
P(x = 1) = 0.15, P(x = 2) = 0.2, P(x = 3) = 0.4, P(x = 4) = 0.15, P(x = 5) = 0.1
To find the probability that the pitcher will throw more than 3 pitches.
Probability of more than 3 pitches = P(x > 3)
= P(x = 4) + P(x = 5)
= 0.15 + 0.1
= 0.25
P(x > 3) = 0.25
Hence the probability that the pitcher will throw more than 3 pitches to a batter is 0.25.
Final answer:
Probability distributions are used to assess the likelihood of different outcomes in a given set of data. To find probabilities, you need to determine the type of probability distribution and use the appropriate formulas or tables.
Explanation:
Probability distributions are used to assess the likelihood of different outcomes in a given set of data. They can take different shapes depending on the nature of the population. One common type of probability distribution is the normal distribution, which represents a bell curve.
To find probabilities using a probability distribution, you can follow these steps:

The measure of an angle is 135 degrees. What is the measure of its supplementary angle ?
Remember that if two angles are supplementary, then the sum of their measures is 180°. So if the measure of an angle is 135 degrees. What is the measure of its supplement?
If the measure of an angle is 135°,
then the measure of its supplement is 45°.
We can find the measure of its supplement by taking 180 minus the measure of the original angle which in this case is 180 - 135 or 45°.
Final answer:
The measure of the supplementary angle to a 135-degree angle is 45 degrees, calculated by subtracting 135 degrees from 180 degrees.
Explanation:
The measure of an angle is 135 degrees. Supplementary angles are two angles whose measures add up to 180 degrees. To find the measure of the supplementary angle, we subtract the given angle's measure from 180 degrees. Here's the calculation:
Identify the measure of the given angle (135 degrees).Subtract the measure of the given angle from 180 degrees: 180 degrees - 135 degrees = 45 degrees.The measure of the supplementary angle is therefore 45 degrees.An apartment building currently has rented x apartments with two occupants and 16 apartments with one occupant. The apartment building has 92 total occupants.
2× + 16 = 92
How many double-occupancy apartments are currently rented?
38 double-occupancy apartments are currently rented
Solution:
Given that, apartment building currently has rented x apartments with two occupants and 16 apartments with one occupant
Number of apartments with one occupant = 16
Number of apartments with two occupants = x
The apartment building has 92 total occupants
Therefore, we frame a equation as,
Number of apartments with one occupant + 2 x Number of apartments with two occupants = 92
[tex]16 + 2 \times x = 92[/tex]
16 + 2x = 92
Solve the above equation for "x"
2x = 92 - 16
2x = 76
x = 38
Thus 38 double-occupancy apartments are currently rented
Final answer:
To determine the number of double-occupancy apartments that are currently rented, we solve the equation: 2x + 16 = 92. After simplifying, we find that there are 38 double-occupancy apartments rented.
Explanation:
To determine the number of double-occupancy apartments that are currently rented, we need to solve the equation: 2x + 16 = 92.
First, we subtract 16 from both sides of the equation: 2x = 76.
Next, we divide both sides of the equation by 2 to isolate x: x = 38.
Therefore, there are 38 double-occupancy apartments currently rented.

Expression for the calculation the sum of the product of 4 and 3 and 1 and 1
Answer:
(4 × 3) + (1 × 1)
Step-by-step explanation:
Sum means adding, so you are adding the product of 4 and 3 to the product of 1 and 1.
Product means multiplying, so you are multiplying 4 and 3 together, and since you just want an expression, this is expressed as 4 × 3.
You are also multiplying 1 and 1 together, so that can be expressed by 1 × 1.
Since you are adding these together, you just put a plus sign in between the two terms. That gives you (4 × 3) + (1 × 1).

An equation for the depreciation of a car is given by y = A(1-r), where y = current value of the car, A = original cost, r = rate
of depreciation, and t = time, in years. The current value of a car is $12,282.50. The car originally cost $20,000 and
depreciates at a rate of 15% per year. How old is the car?
Answer:
Step-by-step explanation:
y = A(1 - r)^t......y = value of car after t years.....A = original cost....r = rate of depreciation.....t = time in years
y = 12,282.50
A = 20,000
r = 15% = 0.15
12,282.50 = 20,000(1 - 0.15)^t
12,282.50 / 20,000 = 0.85^t
0.614125 = 0.85^t
log 0.614125 = t * (log(0.85))
t = (log 0.614125) / (log 0.85)
t = 3 <=== 3 years old
