Step-by-step explanation:
In the figure below, k || m. Find the values of y and x.
Answer:
x = 23
y = 105
Step-by-step explanation:
It's given that lines 'k' and 'm' are the parallel lines and 'l' is a transversal line.
Therefore, y° + 75° = 180° [Sum of consecutive exterior angles = 180°]
y = 180 - 75
y = 105°
And y° + (4x - 17)° = 180° [Linear pair of angles are supplementary]
105 + (4x - 17) = 180
4x + 88 = 180
4x = 180 - 88
4x = 92
x = 23

determine whether the polygon is concave or convex?
Answer: Convex
Step-by-step explanation
The difference between convex and concave polygons lies in the measures of their angles. Another way to think of it is this: the diagonals of a convex polygon will all be in the interior of the polygon, whereas certain diagonals of a concave polygon will lie outside the polygon, on its exterior .Also If the interior angles of of the polygon are less than 180 degrees, then the polygon is convex. But if any one of the interior angles is more than 180 degrees, then the polygon is concave. T∴×∴T that was a lot

5 Select the correct text in the passage. Which sentence best gets across the author's message in the story? A True Victory Kelso and his best friend, Adiel, had spent weeks building their go-cart for the annual Wolf Club go-cart race. Then, at the last minute, another team's go-cart broke down. Adiel and Kelso decided to let that team use their go-cart. But now they were regretting their decision. It was painful watching the race from the sidelines. When the first cart crossed the line, Adiel and Kelso couldn't helping wydering how it would have felt If they had won. Within seconds, other carts raced by. Instead of feeling glum, Kelso began to laugh. He delighted in the breeze that blew through his hair as the go-karts rushed past. Adiel noticed a genuine smile spread wide across Kelso's face. Adiel realized that this sense of happiness was also surging throughout his body, even though he had not raced. "You did a really nice thing today," whispered a nearby Wolf Club leader. "Thanks," said Adlel. "I guess I won't ever know if I could've won the race." "Well winning isn't one of the Wolf Club mottos," said the leader. "But we do believe that we should promise to do our best and do something good for somebody every day. I'd say you proved yourself today as one of the worthiest people here to be called a Wolf Cub." Adiel's mother soon appeared. "And I'm more proud of you now than I ever could have been if you had come in first," she said. Reset Next n. All rights reserved.

solve the quadratic y = −x^2 + 4x + 1 with steps plz!
Answer:
x = -0.24 or 3.73
Step-by-step explanation:
[tex]\frac{-b + \sqrt{b^{2} -4ac } }{2a}[/tex] (There's supposed to be a ± between '-b' and the square root)
[tex]x^{2}[/tex] + 4x + 1 ( [tex]ax^{2} + bx + c[/tex] )
a = -1 ( there's no number before [tex]x^{2}[/tex] so its 1 )
b = 4
c = 1
Substitute into the quadratic equation.
[tex]\frac{-4 + \sqrt{4^{2} -4x1x-1 } }{2x-1}[/tex] ( the [tex]x[/tex] is just the multiplication sign )
= [tex]\frac{-4 + \sqrt{{16} +4 } }{-2}[/tex]
[tex]\frac{-4 + \sqrt{{20} } }{-2}[/tex] = -0.24 [OR] [tex]\frac{-4 - \sqrt{{20} } }{-2}[/tex] = 3.73

The perimeter of a rectangle is 72 m. The width of the rectangle is 16 m. What is the area of the rectangle?
Answer:
320m
Step-by-step explanation
a rectangle has four sides, two pairs of identical sides. So two sides are 16. So that adds up to 32. Perimeter is all sides added together. so it has to add up to 72. 72 minus 32 is 40, so two of the sides have to be 40. Area is length times width, so 16 times 20, which is 320.

x=??
y=??
Answer:
x = 55
y = 45
Step-by-step explanation:
In similar triangles, the ratio between similar sides are the same. So,
AB/ED = BC/EF = AC/DF
Substitute values that they give
6/15 = 18/y = 22/x
Solve 6/15 = 18/y by cross-multiplying
6y = 15*18 = 324
Divide both sides by 6
y= 45
Solve 6/15 = 22/x by cross-multiplying.
6x = 22*15 = 330
Divide both sides by 6.
x = 55
Because there is some dispute between the answers, let's check the ratios.
6/15 = 18/45 = 22/55
0.4 = 0.4 = 0.4
True, x = 55 and y=45
since triangle abc~ def
their sides will be proportional
AB/de=ac/df
6/15=22/x
doing crisscrossed multiplication
6x=22×15
x=22×15/6=55
again
AB/de=BC/EF
6/15=18/y
doing crisscrossed multiplication
6y=15×18
y=15×18/6=15×3=45

The measure of H=90°, the measure of G=80° and FG=75 feet. Find the length of HF to the nearest tenth of a foot
Answer:
The length of HF is 73.9 feet.
Step-by-step explanation:
Let the length of HF be represented by x. So that applying the appropriate trigonometric function to the triangle FGH, we have;
Sin θ = [tex]\frac{opposite}{hypotenuse}[/tex]
Where θ is the angle given in the triangle = [tex]80^{o}[/tex].
Then,
Sin 80 = [tex]\frac{x}{75}[/tex]
⇒ x = Sin 80 x 75
= 0.9848 x 75
= 73.86
x = 73.9
Thus, the length of HF is 73.9 feet.

Drag numbers to show which one is closer to -1 and -1/4 on the number line
Answer:
-0.82 is closest to -1, and -0.28 is closest to -1/4
Step-by-step explanation:
you can start by converting all of them to a fraction or decimal:
-0.28 = -28/100 = -7/25 = -14/50
-0.82 = -82/100 = -41/50
-1/5 = -10/50
-4/5 = -40/50
-1 = -50/50
-1/4 = -12.5/50
does anyone wanna help a gal out with this 6th grade work due today
Answer:
2 - 30ft²
3 - 57yd²
Step-by-step explanation:
Hey There!
The first step in solving this problem is finding the formula for area of a trapezoid
[tex]A = \frac{a+b}{2} h[/tex]
a = base 1
b = base 2
h = height
For the first one the dimensions are
a = 6
b = 9
h = 4
now we just plug in the values
[tex]A=\frac{6+9}{2} 4\\6+9=15\\\frac{15}{2}=7.5\\7.5*4=30[/tex]
so the area of the first trapezoid is 30 ft²
For the second one the given dimensions are
a = 8
b = 11
h = 6
now we just plug in the values
[tex]A=\frac{8+11}{2} 6\\8+11=19\\\frac{19}{2} =9.5\\9.5*6=57[/tex]
so the area of the second trapezoid is 57 yd²

If a f=23cm, find the length of EC.
Answer:
37.3
Step-by-step explanation:
The length of EC shown in the diagram is 37.3.
"To understand the calculation, check below."
TrianglesΔBE -ΔAE= ΔAB
ΔAB=180°-148°
ΔAB=32°
ΔBE -ΔAB-ΔBC=ΔCD (Congruent angles)
ΔCD = 180-32-87
ΔCD =62
EC=61+32
EC=93
L=93•2pi23/360
L=37.3
Therefore , EC=37.3

There are 3 consecutive integers that add up to 15. What is the least of these integers?
Answer:
The answers are 4,5,6,
the answer you are looking for is 4
Step-by-step explanation:
the first thing you have to do is define a variable for stuff that you don't know. In this problem, you don't know any of the integers, so you should assign a variable to them.
will put the first integer as n. The second integer, since it is right after the first, will be n+1. The third integer, since it is right after the second, will be (n+1)+1=n+2. consider the integers 1, 2, and 3. 2 is one more than 1, or in other words, 2=1+1. same for 3, except 3 is two more than 1, so 3=1+2. Since the integers are consecutive, each is one more than the last.We're told that the sum of our three integers is 15. Therefore, n+(n+1)+(n+2)=15 Solving this equation is pretty straightforward:
3n+3=15
3n=12
n=4 That means our first integer is 4. Our second integer is 4+1, or 5, and our third integer is 5+1, or 6. Our answer is confirmed because 4+5+6=15
