100 POINTS!!!!
⦁ Points D, E, and F are not in a line. To construct a circle through points D, E, and F, begin by drawing line segments and . Then construct the perpendicular bisectors of and , and name the point of intersection of the perpendicular bisectors O. How do you know that point O is the center of the circle that passes through the three points? (10 points)
Answer:
O is the center of the circle with radius IE(=ID=EF)
Step-by-step explanation:
Join all 3 points D, E, F, forming the triangle DEF.
Let the midpoint of EF be M and the midpoint of ED be N. (first picture)
Join point I to E, D and F.
Since IN is both an altitude and median to triangle EID, then triangle EID is an isosceles triangle, and IE=ID
similarly, we see that IE=IF.
conclusion: IE=ID=EF.
Answer:
You know its the center of the circle because it is the intersecting point of the perpendicular bisectors of segment DE and EF.

32 = w – 4
1) What is the coefficient?
2) What is the constant?
3) What is the result?
4) What is the variable?
Answer:
1) 1
2.) -4
3.) 32
4.) w
Step-by-step explanation:
Coefficient is the number that is being multiplied by x. W is the same as 1w, so 1 is the coefficient
Constant is the number without any variable that is getting added to the variable (I think that's the definition), and that's -4, because when you subtract a number it's the same as adding it (w+(-4)).
Result is what you're getting, so it is 32, because w-4 equals 32, 32 is the result.
Variable is the unknown value represented by some sort of symbol, which is w, because we don't know w.
W=36

where a = -1, b = -3 and c = = 10:
Answer:
Step-by-step explanation:
-a b-3ab-C+ 3ab2 - 2a² b + ab
where a = -1, b = -3 and c = = 10:
= -(-1)(-3)-3(-1)(-3)-10+3(-1)(-3)2-2(-1)²(-3)+(-1)(-3)
= -(3)-(3)-10+6(3)-2(3)+3
=-3-3-10+18-6+3
=-22+21
= -1

Hilah's soccer team is trying to raise $2414 to travel to a tournament in Florida, so they decided to host a pancake breakfast. Each person must pay $34 for the breakfast. How many people need to attend their breakfast in order to raise $2414?
Answer:
Therefore we understand that exactly 71 people will have to attend breakfast in order to raise 2414 dollars.
Step-by-step explanation
We understand that we have to calculate the amount of people paying for breakfast so if 71 people each pay $34 we would get 2414
= 2414 ÷ 34 (This would give us 71 we get this straight away when we read the problem)
We can also fact check this by doing
= 34 x 71 (This gives us 2414)

Peter works as a delivery person for a bike shipping company. The graph shows a linear model for his delivery times on different days. Peter’s Deliveries What is the equation of the line, first written in point-slope form, and then written in slope-intercept form? Show how you determined the equation. Based on the linear model, predict how long it initially took Peter to deliver his packages (y-intercept). Approximately how much did his delivery time decrease per day (slope)? Complete sentences.I need this done before Monday, please!
Answer/Step-by-step explanation:
✍️The equation of the line in point-slope form:
The equation is given as [tex] y - b = m(x - a) [/tex], where,
(a, b) = a point on the line.
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let's find the slope (m) of the line, housing (3, 21) and (6, 12):
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3 [/tex]
Substitute a = 3 and b = 21, m = -3 into [tex] y - b = m(x - a) [/tex].
Thus, the point-slope equation would be:
✅[tex] y - 21 = -3(x - 3) [/tex]
✍️The equation of the line in slope-intercept form:
Rewrite [tex] y - 21 = -3(x - 3) [/tex], so that y is made the subject of the formula.
[tex] y - 21 = -3x + 9 [/tex]
Add 21 to both sides
[tex] y = -3x + 9 + 21 [/tex]
[tex] y = -3x + 30 [/tex]
✅The slope-intercept equation of the line is [tex] y = -3x + 30 [/tex]
Where,
-3 = how much did his delivery time decrease per day (slope)
30 = how long it initially took Peter to deliver his packages (y-intercept)

What is an inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, an inequality 5-x<2(x - 3) + 5
On solving, we get,
5-x < 2x-6+5
5-x < 2x-1
5+1 < 3x
x < 2
Let y₁ = 5-x, and y₂ = 2(x - 3) + 5

A rectangle has a width of 10cm. The rectangle length is 4 times its width
Answer:
P = 100 centimeters (assuming you are asking for the perimeter)
Step-by-step explanation:
P = 2 (L + W) OR P = 2L + 2W where P equals the perimeter, L equals the length, and W equals the width.
Since the rectangle's length is 4 times its width and given we know the width is 10 centimeters, then the length is 40 centimeters. Now we can substitute these values in our formula, okay?
P = 2 (L + W)
P = 2 (40 + 10)
P = 80 + 20
P = 100 centimeters

Determine if The square root of 9 is rational or irrational and give a reason for your answer.
Answer:
As square root of 9 can be written in the required form for being a rational number, so it is a rational number
Step-by-step explanation:
First of all we'll define rational numbers.
A number that can be written in the form p/q where p and q are integers and q≠0 is called a rational number.
Now we have to check if [tex]\sqrt{9}[/tex] is rational or not, we will check if it can be written in the form p/q
[tex]\sqrt{9} => \frac{\sqrt{9}}{1} => \frac{3}{1}[/tex]
As square root of 9 can be written in the required form for being a rational number, so it is a rational number

Answer:
2x³ + 3x² - 11x - 6
Step-by-step explanation:
f(x) = (2x + 1)(x - 2)(x + 3)
(2x + 1)(x - 2) = 2x² - 3x - 2
(2x² - 3x - 2)(x + 3) = 2x³ - 3x² - 2x + 6x² - 9x - 6 = 2x³ + 3x² - 11x - 6
A dumpling machine automatically inserts mixed vegetables and meat filled wontons into a plastic package. Past experience revealed that some packages were underweight and some were overweight, but most of them had satisfactory weight.
Weight % of Total
Underweight 2.5
Satisfactory 90.0
Overweight 7.5
Required:
What is the probability of selecting two packages that are satisfactory?
a. 0.900
b. 0.729
c. 0.810
d. 0.075
Answer:
c. 0.810
Step-by-step explanation:
Given, total % of satisfactory packages = 90% = 0.90
Now, since selecting a satisfactory package is independent of any other trials (i.e. all the selection trials are independent to each other)
Hence, Probability of selecting two packages that re satisfactory
P(Selecting 2 satisfactory packages) = (0.90)^2
P(Selecting 2 satisfactory packages) = 0.90*0.90
P(Selecting 2 satisfactory packages) = 0.810
Note: We are selecting product since the chance of selecting in each trials are independent.

8x-6y=6
Answer:
Slope intercept form:
8x-6y=6
You should bring the 8x to the other side of the equal sign.
-6y = 6-8x

If a large smoothie takes 1 pound of bananas and 2 pounds of oranges, how much water would it take to grow the fruit?
The total amount of water required to grow the fruit for the smoothie would be approximately (239 - 287) gallons.
What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
Examples:
1 hour = 60 minutes
1 minute = 60 seconds
1 km = 1000 m
We have,
To determine how much water it takes to grow the fruit needed for the smoothie, we need to use the information on water requirements for banana and orange cultivation.
According to the Food and Agriculture Organization (FAO):
Bananas require an average of 800 to 1000 liters (or 211 to 264 gallons) of water per kilogram of fruit produced,
Oranges require an average of 600 to 700 liters (or 158 to 185 gallons) of water per kilogram of fruit produced.
Now,
Assuming that the bananas and oranges used in the smoothie weigh 1 pound and 2 pounds respectively,
or approximately 0.45 kilograms and 0.91 kilograms respectively,
We can estimate the water required to grow the fruit as follows:
Water for bananas:
= 800-1000 liters/kg x 0.45 kg
= 360-450 liters, or 95-119 gallons
Water for oranges:
= 600-700 liters/kg x 0.91 kg
= 546-637 liters, or 144-168 gallons
Therefore,
The total amount of water required to grow the fruit for the smoothie would be approximately (239 - 287) gallons.
