Answer:
The shadow of the windmill will be 24 yards long
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ A bell tower that is 60 yards tall casts a shadow 32 yards long
∴ The tall = 60 yards and the shadow = 32 yards
∵ A windmill is 45 yards tall
∴ The tall = 45 yards
→ By using the ratio method
→ Tall : Shadow
→ 60 : 32
→ 45 : x
→ By using the cross multiplication
∵ x × 60 = 45 × 32
∴ 60x = 1440
→ Divide both sides by 60
∵ [tex]\frac{60x}{60}=\frac{1440}{60}[/tex]
∴ x = 24
∴ The shadow of the windmill will be 24 yards long

48% of what number is 24?
Answer:
[tex]\huge\boxed{50}[/tex]
Step-by-step explanation:
In order to solve for this number, we have to create a percentage proportion.
We know that 24 is 48% of something, so we can create a ratio like this:
[tex]\frac{24}{x}=\frac{48}{100}[/tex]
We can then cross multiply and then divide to find the value of x.
[tex]24 \cdot 100 = 2400[/tex]
[tex]2400 \div 48 = 50[/tex]
So 24 is 48% of 50.
Hope this helped!
48 percentage of the number 50 is 24.
To find the number, you can set up an equation where 48% of that number is equal to 24.
Let's represent the unknown number as "x."
48% of x is written as 0.48x.
Setting up the equation:
0.48x = 24
To solve for x, divide both sides of the equation by 0.48:
x = 24/0.48
Evaluating this expression:
x = 50
Therefore, 48% of 50 is 24.

If x=5 and the area of the rectangle is 30 what is the other length of the rectangle?
Answer:
The other length would be 6.
Step-by-step explanation:
Rectangle area is l times height. So x is either the length for height. So we have 5 times x = 30. To find the other length we have to take 30/5 which equals 6

Answer:
22 < x < 74
Step-by-step explanation:
Given 2 sides of a triangle with third side x , then
difference of 2 sides < x < sum of 2 sides , that is
48 - 26 < x < 48 + 26 , so
22 < x < 74

Synthetic division is very useful for determining roots of polynomials. Once we have roots, we can easily write the corresponding factors.
Write out possible factors of 6: {±1, ±2, ±3, ±6}
Let's determine whether or not -2 is a root. Set up synthetic division as follows:
-2 / 1 -2 -5 6
-2 8 -6
-----------------------
1 -4 3 0
since the remainder is zero, we know for sure that -2 is a root and (x + 2) is a factor of the given polynomial. The coefficients of the product of the remaining two factors are {1, -4, 3}. This trinomial factors easily into {(x -1), (x - 3)}.
Thus, the three factors of the given polynomial are {(x + 2), (x - 1), (x - 3)}

Write a slope-intercept form equation for a line that passes through (0,4) and (2,-2).
Show the step by step process please.
Answer:
-3
Step-by-step explanation:
Slope is essentially change in height over change in horizontal distance, and is often referred to as "rise over run." It has applications in gradients in geography as well as civil engineering, such as the building of roads. In the case of a road the "rise" is the change in altitude, while the "run" is the difference in distance between two fixed points, as long as the distance for the measurement is not large enough that the earth's curvature should be considered as a factor. The slope is represented mathematically as:
m =
y2 - y1
x2 - x1
i want to purchase a necklace for 325$ . ive already saved 115.00 and can set aside 22.00$ a week . which inequality can be used to find the number of weeks it will take to save at least 325.00$?
Answer:
22w + 115 = 325 w = about 10 weeks
Step-by-step explanation:
The first part of this inequaltiy is 22w. Since he/she will set aside $22 a week, you would put a variable because the number of weeks you will need to set aside $22 is unknown therefore you put a variable that makes sense. I put w because you can say that w=weeks. The next part of the inequality is adding $115 because he/she has already saved $115 so we add that to 22w. Finally 22w+115 has to equal $325 because that is how much the necklace costs. Hope this helps!
A brand new car costs $18,000, this price depreciates at 25% every year, how much would the car be after 12 years? 20 years?
Answer:
C(12)=$570.18
C(20)=$57.08
Step-by-step explanation:
Exponential Decay Function
The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.
An exponential decaying function is expressed as:
[tex]C(t)=C_o\cdot(1-r)^t[/tex]
Where:
C(t) is the actual value of the function at time t
Co is the initial value of C at t=0
r is the decaying rate, expressed in decimal
The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.
The depreciation model is:
[tex]C(t)=18,000\cdot(1-0.25)^t[/tex]
Operating:
[tex]C(t)=18,000\cdot 0.75^t[/tex]
At t=12 years, the price will be:
[tex]C(12)=18,000\cdot 0.75^{12}[/tex]
C(12)=$570.18
At t=20 years, the price will be:
[tex]C(20)=18,000\cdot 0.75^{20}[/tex]
C(20)=$57.08

Lines p, q, r, and s are coplanar. If like p is perpendicular to line q, line q is perpendicular to line r, and line s is parallel to line p, then what conclusion can we make about lines s and r?
A. Lines s and r are parallel
B. Lines s and r are perpendicular
C. Lines s and r are neither parallel nor perpendicular
D. No conclusion can be made
Answer:
A
Step-by-step explanation:
To get the answer here, we simply start looking from what we had initially
From the initial point, we can see that line p and line r are perpendicular
The reason for this is because, line q serves as a point for the two and since q is perpendicular to p and r, then p and r are perpendicular
So since s is parallel to like p and line p
is perpendicular to r, then r and and s must be parallel too

Write the equation of the line fully simplified slope intercept form
Answer:
y = - 5x - 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, 0) and (x₂, y₂ ) = (0, - 5) ← 2 points on the line
m = [tex]\frac{-5-0}{0+1}[/tex] = - 5
The line crosses the t- axis at (0, - 5) ⇒ c = - 5
y = - 5x - 5 ← equation of line

What is a sequence?
The sequential ordering of two or more things. two or more objects in orderly succession and orderly chronology. an orderly collection of items or concepts that are connected. something that occurs after another event or series of events.
An enumerated collection of things in mathematics known as a sequence allows repetitions and emphasizes the importance of order. It has members, similar to a set. The sequence's length is expressed in terms of its number of elements.
The word "sequence" refers to a grouping of connected items or occasions, or the succession of their occurrences. A group of numbers in a certain order is called a sequence. There are positions first, second, third, and so on for each phrase in a series.
[tex]n=12\\n-7 = 12-7 =5\\n=5\\n-7 = 5 - 7 = -2\\n=-2\\ -2 -7 = -9[/tex]
Therefore, the equation that can be used for the nth term of the sequence of 12, 5, -2, -9, and many more will be “n-7”.

Question in picture solve
Answer:
x= 13.5
Step-by-step explanation:
f(x) = 2x + 9
f(x) = 36
Set the 2 equations equal to each other;
2x + 9 = 36
Subtract 9 from both sides;
2x = 27
Divide both sides by 2;
x = 13.5
Check:
f(x) = 2x + 9
f(13.5) = 2(13.5) + 9= 27 + 9 = 36
