Answer: 63 ft
Step-by-step explanation:
We can think of the shadow and height of objects as the catheti of a triangle rectangle.
We also know the relationship:
Tan(θ) = (opposite cathetus)/(adjacent cathetus)
if we define:
Tan(θ) = k (a real number, such that will be the same number for every object, because it depends on the angle θ that will depend on the position of the sun)
opposite cathetis = heigt.
adjacent cathetus = length of the shadow.
Then we have:
k = height/length of the shadow.
For the mailbox, we know that the height is (4 + 1/2) ft and the shadow is 6ft long, then we have the equation:
k = (4 + 1/2)ft/6ft = 0.75
Then for the ferris wheel we know:
shadow length = 84ft
we can write the same equation as above:
k = 0.75 = height/84ft
0.75*84ft = height = 63ft
The ferris wheel is 63 ft high.
Answer:
63 feet

Answer:
6 times.
Explanation:
Since she served 3 salads that contain 2/3 cup of blueberries each, and her measuring cup only holds 1/3 cup, she'll have to measure the blueberries 6 times in total, doing 2 measurements per salad (2 x 1/3 = 2/3). Since 2 x 1/3 cup is 2/3 cup, and there are 3 salads in total (multiply 2 measurements by 3 salads), this means she measures the blueberries 6 times.

A coin toss bet is placed between two friends such that the person who wins four tosses first is the winner. What is the total number of possible ways in which the bet can play out
Answer:
who wins four tosses first is the winner.
possible cases-7 tosses, 6 tosses, 5 tosses, 4 tosses
We get cases of Win of Head first-4 tosses
All 4 must be Head
Number of ways = 1
5 tosses-5th must be Head
there are 3 Head out of 4 in ⁴C₃ = 4 Ways
6 tosses-6th must be Head
there are 3 Head out of 5 in ⁵C₃ = 10 Ways
7 tosses-7th must be Head
there are 3 Head out of 6 in ⁶C₃ = 20 Ways
Cases of Head wins = 1+ 4 + 10 + 20 = 35
similarly cases when Tails Wins = 35
Total Possible cases = 35 + 35 = 70
70 is total number of possible ways in which the bet can play out.

Which of the following formulas can be used to calculate the area of a circle with diameter d?
Answer:
The last one
Step-by-step explanation:
To find an area of a circle its with the formula...
A = π [tex]r^{2}[/tex]
But since the diameter is given, and not the radius we need to divide the diameter by 2 (since half the diameter gives you the radius)
And the only one there that divides the diameter with the correct formula is the last one

Answer:
Step-by-step explanation:
[tex]\frac{5x - 2}{4}+\frac{1}{2}=\frac{3y+2}{2}[/tex]
Multiply the equation by 4
[tex]4*\frac{5x - 2}{4}+4*\frac{1}{2}=4*\frac{3y+2}{2}\\[/tex]
5x - 2 + 2 = 2*(3y + 2)
5x +0 = 2*3y + 2*2
5x = 6y + 4
5x - 6y = 4 --------------------(I)
[tex]\frac{7y+3}{3}=\frac{x}{2}+\frac{7}{3}\\[/tex]
Multiply the equation by 6
[tex]6*\frac{7y+3}{3}=6*\frac{x}{2}+6*\frac{7}{3}\\[/tex]
2*(7y + 3) = 3x + 2*7
14y + 6 = 3x + 14
14y = 3x + 14 - 6
14y = 3x + 8
-3x + 14y = 8 ------------------------(II)
Multiply equation (I) by 3 and equation (II) by 5 and then add
(I)*3 15x - 18y = 12
(II)*5 -15x + 70y = 40 {Now add}
52y = 52
y = 52/52
y = 1
Substitute y =1 in equation (I)
5x - 6*1 = 4
5x - 6 = 4
5x = 4 +6
5x = 10
x = 10/5
x = 2

What is the distance from L to M?
A. 10 units
B. 14 units
C. 2 units
D. 100 units
Answer:
[tex]LM = 10units[/tex]
Step-by-step explanation:
[tex]L( - 5,4),M(3, - 2)[/tex]
[tex]L( - 5,4),M(3, - 2) \\ L( { x }_{ 1 } , { y }_{ 1 } ),M( { x }_{ 2 } , { y }_{ 2 } )[/tex]
[tex]LM = \sqrt{ {( { x }_{ 2 } - { x }_{ 1 } )}^{2} + {( { y }_{ 2 } - { y }_{ 1 } ) }^{2} } [/tex]
[tex]LM = \sqrt{ {(3 - - 5)}^{2} + {( - 2 - 4)}^{2} } [/tex]
[tex]LM = \sqrt{ {(3 + 5)}^{2} + {( - 2 - 4)}^{2} } [/tex]

Plot the intercepts to graph the equation. x+y=3
Use the graphing tool to graph the equation. Use the intercepts when drawing the line. If only one intercept exists, use it and another point to draw the line.
Answer: You will have points plotted at +3 on the y axis, and +3 on the x axis.
The attachment shows what your graph should look like.
Step-by-step explanation:
The intercept is where the graphed line crosses an axis.
To find the y-intercept, substitute 0 for x and solve for y:
0 + y = 3. Subtracting 0, you have y = 3
So you can plot a point at +3 on the y axis.
To find the x- intercept, substitute 0 for y, and solve for x
x + 0 = 3 Again, subtracting 0, x = 3
So plot a point on the x-axis at +3
Use the line tool to connect the two points.
A bag contains 2 RED beads, 6 BLUE beads, and 12 GREEN beads. If a single bead is picked at random, what is the probability that the bead is RED or GREEN
Answer:
70% probability that the bead is RED or GREEN
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question, we have that:
2 + 12 = 14 red or green beads out of 2 + 6 + 12 = 20 beads
14/20 = 0.7 = 70%
70% probability that the bead is RED or GREEN

A professional soccer player has a large collection of headbands in their wardrobe comprised of five different colours. The headbands can only be distinguished by their colour. If the soccer player grabs four headbands from their wardrobe for an upcoming soccer tournament, how many possible outcomes are there
Answer: There are 70 outcomes.
Step-by-step explanation:
The number of combinations for n things if r thing s have been chosen ( repetition is allowed) = [tex]C(n+r-1, n-1)[/tex]
Here , n= 5 , r= 4
The possible outcomes = [tex]C(5+4-1, 5-1)= C(8,4)[/tex]
As [tex]C(n,r)=\dfrac{n!}{r!(n-r)!}[/tex]
So, The possible outcomes = [tex]\dfrac{8!}{4!(8-4)!}[/tex]
[tex]=\dfrac{8\times7\times6\times5\times4!}{4\times3\times2\times1\times4!}\\\\=70[/tex]
Hence, there are 70 outcomes.

A rectangle has a length of 12 inches has a perimeter of 38 inches. What is the missing side of the rectangle ?
What is the area of the rectangle ?
Answer:
The area is 84. The missing side is 7.
Step-by-step explanation:
Okay so perimeter = length+length+width+width right? If 12 is the length, then 12+12=24, which is the length part of perimeter. 38-24=14 and 14/2=7. The missing side is 7 because 12+12+7+7=38 and the area is 84 because 12x7=84. Good luck!

The areas of two rectangles can be represented by the functions shown.
Which function represents the difference in the areas, h(x) = f(x) – g(x)?
h(x) = 4x2 – 4x – 11
h(x) = 4x2 – 4x + 11
h(x) = –4x2 + 4x + 11
h(x) = 4x2 – 4x – 9
Answer:
B. h(x) = 4x² - 4x + 11
Step-by-step explanation:
Given:
f(x) = 5x² - 2x + 1
g(x) = x² + 2x - 10
Required:
h(x) = f(x) - g(x)
Solution:
h(x) = (5x² - 2x + 1) - (x² + 2x - 10)
= 5x² - 2x + 1 - x² - 2x + 10 (distributive property)
Collect like terms
= 5x² - x² - 2x - 2x + 1 + 10
h(x) = 4x² - 4x + 11

Write a function inches_to_ft that takes a number of inches x and returns the number of feet. One foot equals 12 inches.
Answer:
def inch_to_feet (x):
return 1/x
Step-by-step explanation:
Implementating the program Using python 3 :
def - - - > function declaration keyword
inch_to_feet - - > function name
x - - > argument which the function takes
The value returned is a conversion of x which is in inches to feets
1/12 feet = 1 inch
To see the value returned ;
We can run the code :
def inch_to_feet(x):
return (1/12)*x
b = inch_to_feet(12)
print(b)
The code above will print 1.
