Answer:
1 is correct, 100.
2 is 500, not 470. since we're rounding to the nearest hundred, we would look at the tens place and if it's higher than 5 then round up.
3 is correct.
4 is correct.
5 is correct.
6 is correct.
7 is correct.
8 is 290, not 300. like i said before, but in this case we're rounding t the nearest ten instead of hundred. but the same rules apply.
9 is correct.
and 10 is correct!
i think that you did pretty well on most of these, but remember the rounding rule.
Buffalo Bart’s Endless Wings charges $5.60 for sides and a drink, and then $0.40 per chicken wing. The Spicy Chicken charges $10 for sides and a drink, and then $0.20 per chicken wing. About how many chicken wings must be purchased so that the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken is the same?
Answer:
22.
Step-by-step explanation:
About 22 chicken wings must be purchased for the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken to be the same.
Let's represent the number of chicken wings as "x".
The total cost at Buffalo Bart’s Endless Wings would be the sum of the initial cost for sides and a drink ($5.60) and the cost per chicken wing ($0.40 per wing times x):
Total cost at Buffalo Bart’s Endless Wings = $5.60 + $0.40x
The total cost at The Spicy Chicken would be the sum of the initial cost for sides and a drink ($10) and the cost per chicken wing ($0.20 per wing times x):
Total cost at The Spicy Chicken = $10 + $0.20x
To find the number of chicken wings where the total costs are the same, we'll set up an equation:
$5.60 + $0.40x = $10 + $0.20x
Now, solve for "x":
$0.40x - $0.20x = $10 - $5.60
$0.20x = $4.40
Divide both sides by $0.20:
x = $4.40 / $0.20
x = 22
So, about 22 chicken wings must be purchased for the total cost at Buffalo Bart’s Endless Wings and The Spicy Chicken to be the same.

Answer:
<1=23
Step-by-step explanation:
If WXZ contains both <1 and <2, and <2 is 4 times <1, then we can set this up as x + 4x = 115
This is easily simplified to 5x = 115
Divide both sides by 5 and you will get x=23

A jumping spider's movement is modeled by a parabola. The spider makes a single jump from the origin and reaches a maximum height of 10 mm halfway across a horizontal distance of 80 mm.
Part A: Write the equation of the parabola in standard form that models the spider's jump. Show your work. (4 points)
Part B: Identify the focus, directrix, and axis of symmetry of the parabola. (6 points)
The spider's movement is an illustration of a parabola.
The equation of the parabola is: [tex]\mathbf{y = -\frac{1}{320}(x - 80)^2 + 20}[/tex]The focus of the parabola is [tex]\mathbf{Focus = (80 ,-60)}[/tex]The directrix is: [tex]\mathbf{y = 100}[/tex].The axis of symmetry is: [tex]\mathbf{x = 80}[/tex](a) The equation
The spider passes through the origin.
So, we have:
[tex]\mathbf{(x,y) = (0,0)}[/tex]
The spider jumps to a maximum height of 20mm, midway 160mm.
So, the vertex is:
[tex]\mathbf{(h,k) = (80,20)}[/tex]
The equation of a parabola is:
[tex]\mathbf{y = a(x - h)^2 + k}[/tex]
So, we have:
[tex]\mathbf{0 = a(0 - 80)^2 + 20}[/tex]
[tex]\mathbf{0 = 6400a + 20}[/tex]
Subtract 20 from both sides
[tex]\mathbf{6400a =- 20}[/tex]
Solve for a
[tex]\mathbf{a =- \frac{1}{320}}[/tex]
Substitute [tex]\mathbf{a =- \frac{1}{320}}[/tex] and [tex]\mathbf{(h,k) = (80,20)}[/tex] in [tex]\mathbf{y = a(x - h)^2 + k}[/tex]
[tex]\mathbf{y = -\frac{1}{320}(x - 80)^2 + 20}[/tex]
(b) The focus, directrix and the axis of symmetry
The focus of a parabola is:
[tex]\mathbf{Focus = (h,k+p)}[/tex]
Where:
[tex]\mathbf{p = \frac{1}{4a}}[/tex]
So, we have:
[tex]\mathbf{p = \frac{1}{4\times -1/320}}[/tex]
[tex]\mathbf{p = -\frac{320}{4}}[/tex]
[tex]\mathbf{p = -80}[/tex]
So, we have:
[tex]\mathbf{Focus = (80 , 20-80)}[/tex]
[tex]\mathbf{Focus = (80 ,-60)}[/tex]
The axis of symmetry is:
[tex]\mathbf{x = h}[/tex]
So, we have:
[tex]\mathbf{x = 80}[/tex]
The directrix is:
[tex]\mathbf{y = k - p}\\[/tex]
So, we have:
[tex]\mathbf{y = 20+80}[/tex]
[tex]\mathbf{y = 100}[/tex]

positive coterminal angle:
negative coterminal angle:
Answer:
0° and 90°, it's Ql. If between 90° and 1800 QQ. ... Find a positive and a negative conterminal angle for the given angle.
Step-by-step explanation:
The positive and negative coterminal angles to -32° are:
Positive coterminal angle = 688°
Negative coterminal angle = -392°
What is a coterminal angle?Coterminal angles are those whose terminal sides and beginning sides coincide.
The given angle measure is -32°.
The positive coterminal angle is:
-32° + 360°
= 328°
Since the angle is not between 500° and 1000°, add 360° one more times:
328° + 360°
= 688°
The negative co-terminal angle is:
-32° - 360°
= -392°
Hence, the positive and negative coterminal angles to -32° are:
Positive coterminal angle = 688°
Negative coterminal angle = -392°

18x²y - 8a + 14bStep-by-step explanation:
The Sum:
3x²y - 5a + 4b + (-9x²y - 7b + 4a) = 3x²y - 9x²y - 5a + 4a + 4b - 7b = -6x²y - a - 3bThe difference:
3x²y - 5a + 4b - (-9x²y - 7b + 4a) =3x²y + 9x²y - 5a - 4a + 4b + 7b =12x²y - 9a + 11bSubtract the sum from the difference:
12x²y - 9a + 11b - (-6x²y - a - 3b) = 12x²y + 6x²y - 9a + a + 11b + 3b =18x²y - 8a + 14bAnswer:
See below.
Step-by-step explanation:
First Let's us find the sum.
[tex]\sf\longmapsto \: 3x²y - 5a + 4b + (-9x²y - 7b + 4a)[/tex]
[tex]\sf\longmapsto3x²y - 9x²y - 5a + 4a + 4b - 7b [/tex]
[tex]\sf\longmapsto \: -6x²y - a - 3b[/tex]
Now, let's us find the difference (minus)
[tex]\sf\longmapsto \: 3x²y - 5a + 4b - (-9x²y - 7b + 4a)[/tex]
[tex]\sf\longmapsto3x²y + 9x²y - 5a - 4a + 4b + 7b[/tex]
[tex]\sf\longmapsto \: 12x²y - 9a + 11b[/tex]
Now minus the sum from the difference.
[tex]\sf\longmapsto \: 12x²y - 9a + 11b - (-6x²y - a - 3b)[/tex]
[tex]\sf\longmapsto \: 12x²y + 6x²y - 9a + a +11b + 3b[/tex]
[tex]\sf\longmapsto \: 18x²y - 8a + 14b[/tex]
Therefore,[tex]\sf\longmapsto \: 18x²y - 8a + 14b[/tex] is the answer.
