QUICKLY PLEASE JIMGRANT1 IF YOU WOULD PLEASE HELP.
Answer:
x=120°
Step-by-step explanation:
Let us draw a third horizontal line through x, parallel to the two parallel lines.
This line divides angle X into A and B as shown.
By alternate interior angle theorem, angle B=50°
and
angle A=70°
We know that: A+B=x
Therefore x=70°+50°=120°
Answer:
x=120 degrees

Period = Equation of the mideline:
Maximum = Minimum =
Answer:
Period =½
Equation of midline, y=0
Maximum =2
Minimum=-2
Step-by-step explanation:
The given function is
[tex]f(x) = - 2 \cos(4 \pi \: x) [/tex]
The period is given by:
[tex] \frac{2\pi}{b} = \frac{2\pi}{4\pi} = \frac{1}{2} [/tex]
The equation of the midline is y=0 since there is no vertical shift
The amplitude of this function is 2 so the range is -2≤y≤2.
Hence the maximum value is 2 and minimum value is -2

There are 8 soccer matches per day at Greenville's annual soccer tournament, which lasts 17 days. Estimate the number of soccer matches during the tournament by rounding the larger number to the nearest ten.
The estimation of the total number of soccer matches in Greenville's annual tournament, with 8 matches each day for around 20 days, is approximately 160 matches.
Explanation:The student is asking for an estimation of the total number of soccer matches in Greenville's annual tournament. There are 8 matches each day, and the tournament runs for 17 days. The part of the question that asks you to round to the nearest ten refers to the 17 days, as this is the larger number. Rounding 17 days to the nearest ten would give us 20 days. Therefore, to estimate:multiply the rounded number of days (20) by the number of matches per day (8), yielding an estimate of 160 soccer matches during the tournament.

#SPJ12
Final answer:
The estimated number of soccer matches during Greenville's annual soccer tournament is 160 matches, calculated by rounding 17 days to 20 and multiplying by 8 matches per day.
Explanation:
To estimate the number of soccer matches during Greenville's annual soccer tournament, we round the larger number (17 days) to the nearest ten. Since 17 is closer to 20 than it is to 10, we round up to 20 days for our estimation. With 8 soccer matches per day, we then calculate the estimated number of matches as 8 matches/day × 20 days.
8 matches/day × 20 days = 160 matches
Therefore, an estimated 160 soccer matches will be played during the tournament.

factor the expression below x^2-16x+64
Answer:
(x - 8)^2
Step-by-step explanation:
Factor the following:
x^2 - 16 x + 64
The factors of 64 that sum to -16 are -8 and -8. So, x^2 - 16 x + 64 = (x - 8) (x - 8):
(x - 8) (x - 8)
(x - 8) (x - 8) = (x - 8)^2:

Sales Gi sells televisions. He earns a fixed amount for each television and an additional $ 20 if the buyer gets an extended warranty. If Gi sells 18 televisions with extended warranties, he earns $ 1 ,260. How much is the fixed amount Gi earns for each television? PLZZ HELP :)
Answer:
$50
Step-by-step explanation:
Simple math
Extended warranty don’t count so gotta take that out that’s be 20x18=360 1260-360=900 now divide 18 tvs from that and u get 900/18=50
To determine the fixed amount Gi earns for each television, a simple algebraic equation is set up and solved to find that he earns $ 50 per television without the extended warranty.
Explanation:To solve for the fixed amount Gi earns for each television without the extended warranty, we can set up an equation.
Let's call the fixed amount $F. Each television with an extended warranty earns Gi an additional $ 20, so for each of those televisions, he earns $F + $20. If he sells 18 televisions with extended warranties,
the total amount he earns can be represented by 18($F + $ 20), which equals $ 1,260 according to the question.
We can create the following equation to find the fixed amount $F:
18($F + $ 20) = $ 1,260
To solve for $F, divide both sides of the equation by 18:
$F + $ 20 = $ 70
Then, subtract $ 20 from both sides to isolate $F:
$F = $ 50
So, the fixed amount Gi earns for each television is $ 50.

What is the sum of the EXTERIOR angles of an octagon?
Answer:
A rule of polygons is that the sum of the exterior angles always equals 360 degrees. Since it is a regular octagon, so each of the interior angles of octagon are equal. ((n-2)*180)/n where n is the number of sides of the polygon.for example in case n=8 for an octagon, so we get:
((8-2)*180)/8 => (6*180)/8 => 1080/8 = 135 degrees. This means that each interior angle of the regular octagon is equal to 135 degrees.
Each exterior angle is the supplementary angle to the interior angle at the vertex of the polygon, so in this case each exterior angle is equal to 45 degrees. (180 - 135 = 45). Remember that supplementary angles add up to 180 degrees.
And since there are 8 exterior angles, we multiply 45 degrees * 8 and we get 360 degrees.
This technique works for every polygon, as long as you are asked to take one exterior angle per vertex.
The sum of the exterior angles of any polygon, including an octagon, is always 360 degrees. This is true regardless of the polygon's number of sides, because when one traces around the polygon, the point will have made one full revolution, or 360 degrees.
Explanation:
In mathematics, the sum of the exterior angles of any polygon, not just an octagon, is always 360 degrees. This applies regardless of the number of sides the polygon has. The concept comes from observing how a point moves as one traces around the polygon: during the complete circuit, it will have made exactly one full revolution, which is 360 degrees in total. Just as a circle consists of 360 degrees, this concept applies to polygons and their exterior angles as well.

A {3, 7, 11}
B {-8, - 2, 3, 4, 7, 11}
c {-8, -2, 4}
Answer:
B) {-8,-2,3,4,7,11}
Step-by-step explanation:
range is y
Final answer:
The range of the set of points {(3, 4), (7, -2), (11, – 8)} is the set of their y-values, which are -8, -2, and 4. So the range is {-8, -2, 4}.
Explanation:
The range of a set of points in mathematics refers to the difference between the highest and lowest y-values (also known as the vertical coordinate) in the set. Looking at the provided set of points {(3, 4), (7, -2), (11, – 8)}, we identify the y-values as 4, -2, and -8. To find the range, we look for the highest and lowest y-values. The highest y-value among these points is 4, and the lowest is -8.
The range consists of all the y-values which the function or set of points may take. Consequently, within this set of points, the range encompasses all values from -8 up to 4. Therefore, the correct answer listing those y-values is Option C: {-8, -2, 4}

Stephanie works as a waitress and earns $4.50 an hour. Stephanie's last paycheck was $150. She earns $60 in tips in addition to her hourly pay. Write an equation the represents this situation. How many hours did Stephanie work? Paragraph Please!!!!!!!!!!!
Stephanie worked for 33 hours 20 minutes.
Explanation:
Step 1; Stephanie works and earns $4.50 an hour. Her last paycheck was for $150. So to find the number of hours she has worked we divide the total money earned by the money she earns every hour.
Total hours worked = Total money earned / Money earned for an hour
= $150 / $4.50 = 33.33 hours.
Step 2; We need to convert the 33.33 hours into hours and minutes.
We multiply the 0.33 hours with 60 to convert it into minutes. 0.33 × 60 = 20 minutes. So Stephanie worked for 33 hours and 20 minutes to get her last paycheck.
Answer:
20 hours
Step-by-step explanation:
She receives $60 regardless of the number of hours she works for. Per hour, she earns $4.50. In t hours, she earns:
60 + 4.50t
For some t, the total is $150
150 = 60 + 4.50t
90 = 4.50t
t = 20

The factored form of the expression −1.5w+7.5 is −1.5(w-5), since −1.5 is the common factor for both terms in the expression.
Explanation:The factored form of the expression −1.5w+7.5 can be found by factoring out a common factor. The common factor in this expression is −1.5, as both terms in the expression can be divided by −1.5.
Factoring out −1.5, we get:
−1.5w + 7.5
= −1.5 (w) + −1.5 (-5)
= −1.5 (w - 5)
Therefore, the factored form of −1.5w+7.5 is −1.5(w−5).
