Is EF and GH parralel and how can this be determined?
Answers
Answer:
We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]
Both have same slope, so EF is parallel to GH i.e. EF || GH
Step-by-step explanation:
We need to find Is EF and GH parallel.
If EF and GH are parallel, they have same slopes.
So, we will find slopes of EF and GH
The formula used is: [tex]Slope=\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of EF
We have: E(2,5) and F(7,1)
So, [tex]x_1=2, y_1=5, x_2=7, y_2=1[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{1-5}{7-2}\\Slope=\frac{-4}{5}\\[/tex]
So, slope of EF is [tex]\mathbf{\frac{-4}{5}}[/tex]
Slope of GH
We have: G(2,-3) and F(-3,5)
So, [tex]x_1=2, y_1=-3, x_2=-3, y_2=5[/tex]
Putting values in formula and finding slope
[tex]Slope=\frac{y_2-y_1}{x_2-x_1}\\Slope=\frac{5-(-3)}{-8-2}\\Slope=\frac{5+3}{-10}\\Slope=\frac{8}{-10}\\Slope=\frac{-4}{5}[/tex]
So, slope of GH is [tex]\mathbf{\frac{-4}{5}}[/tex]
We have slope of EF : [tex]\mathbf{\frac{-4}{5}}[/tex] and slope of GH: [tex]\mathbf{\frac{-4}{5}}[/tex]
Both have same slope, so EF is parallel to GH i.e. EF || GH

Step-by-step explanation:
As is often the case with multiple choice questions, you only need to identify a feature of the answer set that distinguishes right from wrong. Here, that can be the lowest-power term, which is always the product of the lowest-power terms.
That product is (-3m)(+m) = -3m². This matches the third answer choice.

Step-by-step explanation:
Two electronics stores sell a video game that has a regular price of $49. A store discounts the video game by $15 and then adds 7.5% sales tax. Store B adds the tax first and then takes the discount. Are the selling prices the same? Justify your answer.
Answers
Answer:
The selling prices are same.
Step-by-step explanation:
According to the problem, given data are as follows:
Regular price = $49
Store A
Discounts first = $15
Price after discount = $49 - $15 = $34
Now adds 7.5% sales tax = $35 + ( $35 ×7.5%) = $35 + $2.625
So, final selling value = $37.625 or $38
Store B
Adds tax first = $49 + ($49 × 7.5%) = $49 + $3.675 = $52.675
Now deduct discount = $52.675 - $15
So, Final selling price = $37.675 or $38
As there is very minimal or no difference between both prices, so this considers to be same.

A cable company uses the formula S = 20,000 (1 + 0.08)y to estimate the number of subscribers, S, that use their service after y years. If there were 20,000 cable television subscribers when the cable company began, what is the meaning of the expression (1 + 0.08)Y?
Answers
Options :
A. Every year the number of subscribers is estimated to increase by 8 over the number
of subscribers the year before.
B. Every year the number of subscribers is estimated to increase by 8% of the original
20,000 subscribers
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
D. Every year the number of subscribers is estimated to increase by 80% of the
original 20,000 subscribers.
Answer:
C. Every year the number of subscribers is estimated to increase by 8% over the
number of subscribers the year before.
Step-by-step explanation:
Given that:
The formula represents an exponential function :
S = 20,000 (1 + 0.08)^y
General form of an exponential equation :
y(x) = ab^x
Where a = initial value ; b = rate of change ; x = time
Comparing the formula given with the general equation:
a = 20000 = Number of subscribers when company began
b^x = (1 + 0.08)^y = percentage increase in the number of subscribers over y years

#27: Three cities form a right triangle on a map. Cities B and C are the furthest
apart. If cities A and B are 14 miles apart and cities A and Care 22 miles about,
how far about are cities B and C? Round the nearest tenth.
Answers
Answer: 26.1miles
Step-by-step explanation:
f three cities A, B and C form a right triangle on a map, and the Cities B and C are the furthest apart, then the distance between cities B and C will be the hypotenuse of the triangle.
If cities A and B are 14 miles apart, then |AB| = 14miles
Also if cities A and C are 22 miles apart, then |AC| = 22miles.
To get |BC| which is the distance between cities B and C, we will use the Pythagoras theorem.
|BC|² = |AB|² + |AC|²
|BC|² = 14²+22²
|BC|² = 196+484
|BC|² = 680
|BC| = √680
|BC| = 26.1miles
This means that cities B and C are 26.1miles apart

Alexia, Benito, and Carmen won a team art competition at their local park. As
part of their prize, they can paint the 5 km (5000 m) paved path through the
park any way they like.
They decided Alexia will paint the first 70 m, then Benito will paint the next
15 m, then Carmen will paint the next 35 m. They will keep repeating this
pattern until they reach the end of the 5 km path.
What percentage of the path will each person paint?
Answers
Answer:
Alexa: 58.8%
Benito: 12.5%
Carmen: 28.7%
Step-by-step explanation:
(70m + 15m + 35m)x=5000
x=41.67 times
41x120m=4920m, leaving 80 m which Alexa and Benito got an extra time.
Alexa painted 42 times
Benito painted 41.67 times
Carmen painted 41 times
Alexa: 42x70m=2940m, 2940/5000=58.8%
Benito: 41.67x15m=625m, 625/5000=12.5%
Carmen: 41x35m=1435m, 1435=/5000=28.7%
