The Empire State Building in New York City is 1250 ft tall. What is the
distance from the top of this building to the horizon to the nearest mile? (Hint: 5280 ft 1 mi; radius of Earth 4000 mi)
Answer:
33 miles
Step-by-step explanation:
The illustration forms a right angled triangle. The opposite side of the triangle is where we are looking for . The adjacent side is the radius 4000 miles.
5280 ft = 1 mile
735 ft = ? miles
cross multiply
735/5280
miles = 0.13920454545 miles
The hypotenuse side is the height of the building + 4000 miles = 0.140 + 4000 = 4000.14 miles
using Pythagoras theorem
c² = a² + b²
c = 4000.14
a = 4000
4000.14² = 4000² + b²
b² = 4000.14² - 4000²
b² = 16001120.0196 - 16000000
b² = 1120.0196
b = √1120.0196
b = 33.4666938911
b = 33 miles
On a coordinate plane, 2 lines are shown. Line M N goes through (negative 4, 8) and (negative 4, negative 6). Line K L goes through (negative 8, 2) and (6, 2). How are lines KL and MN related?
Answer:
Perpendicular lines
Step-by-step explanation:
MN: (-4, 8) and (-4, -6), This line parallel to y-axis as as x-value doesn't change
KL: (-8, 2) and (6, 2), This line is parallel to x-axis as y-value doesn't change
The given lines are perpendicular as one is parallel to x, another one is parallel to y

Answer:
a) is correct3n + 5
1. Substitute the numbers
3(5) + 5 = 15 + 5 = 20
2. Substitute the second number
3(6) + 5 = 18 + 5 = 23
b) Numbers are 8 and 16.This is because I realized I got the number of 4 last because I did 1*2 = 2.
Then I did 2*2 = 4.
So you have to multiply by two to get the next number. Or you can put it to the 4th or 5th exponent of 2.
1. 1
2. 1*2 = 2
3. 2*2 = 4
4. 4*2 = 85. 8*2 = 16A dresser is normally priced at $870. This weekend however, there is a sale where everything is 15% off. If the sales tax on items is 11.6%, what would be the total cost of the dresser?
Answer:
$825.28
Step-by-step explanation:
First, we need to calculate the 15% off sale:
870(0.85) = 739.50
Now, we will calculate and add on the sales tax:
739.50(1.116) = 825.28
So, the final price of the dresser will be $825.28
Hence, the total cost of the dresser is $ [tex]15.138[/tex].
What is the percentage?
Percentages are generally defined as a ratio of any value to the whole value multiplied by [tex]100[/tex].
The symbol used to represent the percentage is %. Percentage means a number or a ratio represented in the form of fractions of [tex]100[/tex]. It is represented using the percentage sign ‘%’.
Here given that,
A dresser is normally priced at $[tex]870[/tex]. This weekend however, there is a sale where everything is [tex]15[/tex]% off. If the sales tax on items is [tex]11.6[/tex]%,
Firstly we will calculate the [tex]15[/tex]% off sale is
[tex]15[/tex]%[tex]=\frac{15}{100}\\\\[/tex]
[tex]15[/tex]%[tex]=0.15[/tex]
So,[tex]870(0.15) =130.5[/tex]
Then,
[tex]\frac{11.6}{100}=0.116[/tex] %
The sales tax on items is [tex]11.6[/tex]% is
[tex]130.5(0.116)=15.138[/tex] $
Hence, the total cost of the dresser is $ [tex]15.138[/tex].

1. Which of the following equations has a solution of x = -5? Equation A------> 16x-7=11x-32 Equation B------> -4x- 10=2x+20 a. Equation A b. Equation B c. Both A and B d. Neither A nor B
Answer:
C
Step-by-step explanation:
Equation A
16x - 7 = 11x - 32
(16x - 7) - 11x = (11x - 32) -11x
5x - 7 = -32
(5x - 7) + 7 = (-32) + 7
5x = -25
(5x)/5 = (-25)/5
x = -5
Equation B
-4x - 10 = 2x + 20
(-4x - 10) - 2x = (2x + 20) - 2x
-6x - 10 = 20
(-6x - 10) + 10 = (20) + 10
-6x = 30
(-6x)/-6 = (30)/-6
x = -5
Both Equation A and Equation B have a solution of -5.

Step-by-step explanation:
the area of a triangle 17.5 square meters. The height of the triangle is 3 meters less than twice it’s base. the base of the triangle is x meters
Answer :
Given that the base of the triangle is x m, the height is 3m less than twice it's base then the height will be represented by the equation:
(2x-3) m
Thus the area will be:
Area=1/2bh
Area=1/2x(2x-3)=17.5
x^2-1.5x=17.5
Writing the above equation is quadratic form of ax^2+bx+c=0 we get:
x^2-1.5x-17.5=0

Compute the factors of [tex]x^{3}-y^{3}[/tex] as follows:
[tex]x^{3}+(-y)^{3}=(x+(-y))(x^{2}-x(-y)+(-y)^{2})[/tex]
[tex]x^{3}-y^{3}=(x-y)(x^{2}+xy+y^{2})[/tex]

Answer:
The numbers are: 8 , 12
Step-by-step explanation:
Ratio of two numbers = 2:3
Two numbers are : 2x , 3x
[tex]\frac{2x +12}{3x +12}=\frac{5}{6}\\\\[/tex]
Cross multiply,
6*(2x + 12) = 5*(3x+12)
6*2x +6*12 = 5*3x + 5*12
12x + 72 = 15x + 60
72 - 60 = 15x - 12x
12 = 3x
3x = 12
x = 12/3
x = 4
2x = 2*4 = 8
3x = 3*4 = 12
The numbers are: 8 , 12

if the 50th and 51st terms of an arithmetic sequence are 140 and 142, find the 1st term
Answer:
The first term is 42.
Step-by-step explanation:
The common difference is 142 - 140 = 2 so we have
50th term = a1 + 2(50 -1) = 140 where a1 is the first term
a1 + 98 = 140
a1 = 140 - 98 = 42.

Answer:
Invariant points = 0
Step-by-step explanation:
When a point (h, k) is translated by a vector [tex]\binom{x}{y}[/tex], rule to be followed,
(h, k) → [(x + h), (y + k)]
Following this rule translated vertices of the rectangle OABC by a vector [tex]\binom{1}{3}[/tex] will be,
O(0,0) → O'(1, 3)
A(3, 0) → A'[(3 + 1), (0 + 3)]
→ A'(4, 3)
B(3, 3) → B'[(3 + 1), (3 + 3)]
→ B'(4, 6)
C(3, 0) → C'[(3 + 1), (0 + 3)]
→ C'(4, 3)
Therefore, every point on the perimeter of the square will get changed.
Number of invariant points = 0

PLEASE HELP ASAP! IT'S EASY WORD PROBLEM!!!!!!!! My computer can download a movie in 5 hours. If I install an extra processor it can download the movie in 4 hours. How long, working alone, would it have taken the new extra processor to download the movie?
Answer:
t = 2,22 h
Step-by-step explanation:
At the beginning with the first processor, we download in 5 hours the whole movie, then in 1 hour, that processor downloads 1/5 of the movie.
If with the two processors we download the movie in 4 hours in 1 hour we download 1/4 of the movie.
In 1 hour with the two processors, we get 1/4, and in 1 hour with the old processor we get 1/5
Then in 1-hour the old processor plus contribution of the new one will download 1/4 of the movie or
1/5 + x = 1/4
x = 1/4 - 1/5
x(h) = 5 + 4 /20 x = 9/20 or 0,45 of the movie in 1 hour
Working along the new processor will do 0,45 ( 9/20) in 1 hour, to finish the whole movie it will need to download 11/20
If in 1 hour download 9/20
x 11/20
x(r) = (11/20) / (9/20) = 11/9 x(r) = 1,22 (h)
Then total time for the new processor to download the movie is:
t = 1,22 + 1
t = 2,22 h

Melody randomly selected two apples without replacing the first apple from the crate containing 10 granny Smith apples, 14 Red delicious apples, four golden delicious apples, and 18 Braeburn apples. What is the probability that Melody selected a golden delicious apple first and a granny Smith apple second?
Answer:
[tex]P = \frac{5}{282} = 0.0177[/tex]
Step-by-step explanation:
First we need to find the total amount of apples in the crate:
Total = 10 + 14 + 4 + 18 = 46 apples
The probability of the first apple being a golden delicious apple is the number of those apples over the total number of apples:
[tex]P(golden) = \frac{N(golden)}{N(total)}[/tex]
[tex]P(golden) = \frac{4}{48} = \frac{1}{12}[/tex]
Then, the probability of the second apple being a granny Smith apple is the number of those apples over the total number of apples, but now the total number of apples is one less, because one apple was removed from the crate:
[tex]P(granny) = \frac{N(granny)}{N(total)-1}[/tex]
[tex]P(granny) = \frac{10}{47}[/tex]
The final probability we want is the product of those two probabilities:
[tex]P = P(golden) * P(granny) = \frac{1}{12} \frac{10}{47} = \frac{10}{564} = \frac{5}{282}= 0.0177[/tex]
