Answer: 14
Step-by-step explanation:
To find the distance, find the difference in the x and y values,square them and add them. Then finally find the square root of the number you got after adding them together.
-2-(-1)= -1
-8 -6 = -14
-14^2 + -1^2 = d^2 where d is the distance
196 + 1 = d^2
197 = d^2
d= [tex]\sqrt{197}[/tex]
d= 14.0356 rounded to the nearest tenth is 14.
Which can be used to prove that lines are parallel? 1.Vertical Angle Theorem 2.Alternate Interior Angles Theorem 3.Converse of Corresponding Angles Postulate 4.Converse of Same-Side Interior Angles Theorem
Answer:
4. Converse of Corresponding Angles Postulate
Step-by-step explanation:
There are several theorems to prove line relationships in plane geometry.
The proof of parallel lines is done by
(3) Converse of Corresponding Angles Postulate(4) Converse of Same-Side Interior Angles TheoremTo prove that lines are parallel, we make use of the concept of line transversal.
The vertical angle theorem is based on two lines intersecting at a point
The alternate interior angle theorem is used to determine the congruence of angles in a transversal of parallel lines
The converse of corresponding angles postulate, and the converse of same-side interior angles theorem are used to determine if lines are parallel based on the angles on the transversal.
Hence, the true options are (3) and (4)

What is the slope of the line that contains these points? x| -7. -6. -5. -4 ------------------------------------------------------------- y| 21. 17. 13. 9
Answer:
-4Step-by-step explanation:
Given the line containing the points.
x | -7. -6. -5. -4
y | 21. 17. 13. 9
The slope of the line is expressed as m = Δy/Δx = y₂-y₁/x₂-x₁
Using the coordinates y (21, 17) and corresponding value of x(-7, -6)
y₁ = 21, y₂ = 17 x₁ = -7, x₂ = -6
Substituting the values into the formula for calculating the slope, we have;
m = Δy/Δx = 17-21/-6-(-7)
m = -4/-6+7
m = -4/1
m = -4
Hence the slope of the line that contains these points is -4

Owen bought 7 pounds of bananas for
$8.75. Olive bought 10 pounds of
grapes for $12. How much lower was
Olive's unit rate than Owen's unit rate?
Answer:
$0.05/lb
Step-by-step explanation:
What Owen paid, per pound: ($8.75) / (7 lb) = $1.25/lb
What Olive paid, per pound: ($12) / (10 lb) = $1.20/lb
Olive's unit rate was $0.05/lb lower than Owen's.
find the distance between points (2,5) and (-2,2)
Answer:
5
Step-by-step explanation:
Let :
x(1) be 2
y(1) be 5
x(2) be -2
y(2) be 2
We know that distance between any 2 points is equal to:-
[tex] \sqrt{{(x(2) - x(1) )}^{2} + ({y(2) - y(1))}^{2} } [/tex]
So using the above formula ,

we have 10 marbles. five are blue Five are red. we select three marbles. what are the odds (in percent) that all three chosen are red?
Answer:
12.5%
Step-by-step explanation:
Step 1:
We need to find out the percentage of picking a marble that is red. In total, there are 10 marbles, and there are 5 red. To find the probability of picking a red marble, you need to do:
# of red / total marbles.
There are 5 red marbles and 10 total marbles, so the probability of getting a red marble is 5/10, and you can simplify it to 1/2 (5/10 * 5/5).
Step 2:
Now we can start finding the probability of finding the probability of choosing three red marbles in a row. Since we need to find the probability of choosing red marbles three times, you can multiply 1/2 by itself 3 times (1/2 * 1/2 * 1/2).
1/2 * 1/2 * 1/2 = 1/8
Step 3:
Now we need to convert the fraction into a percentage. You can find the percentage by dividing 1 by 8. You should get 0.125, and you can multiply 0.125 by 100, and your final answer should be 12.5%.

Step-by-step explanation:
Hope it is helpful for you
please follow me
Answer: X = 69° and Y = 111°
Step-by-step explanation: X is a z-angles which makes it the same as the given angles. Y is a corresponding angle which makes it the same as the above angle 111°.
The two figures below, a regular hexagon and a regular pentagon, have the same
perimeter. What is the length of a side of the pentagon?
Answer:
69
Step-by-step explanation:
Perimeter = sum of all sides of a regular polygon = the number of sides*length of a side
Length of a side of the given regular hexagon = 3x + 5
Perimeter of hexagon = 6(3x + 5) = 6(3x) + 6(5) = 18x + 30
Length of a side of the given regular pentagon = 4x - 1
Perimeter of pentagon = 5(4x - 1) = 5(4x) - 5(1) = 20x - 5
Since we are told that the perimeter of the regular hexagon is the same as that of the regular pentagon, therefore:
18x + 30 = 20x - 5
Solve for x.
Subtract 20x from both sides
18x + 30 - 20x = 20x - 5 - 20x
-2x + 30 = -5
Subtract 30 from both sides
-2x+ 30 - 30 = -5 - 30
-2x = -35
Divide both sides by -2
x = -35/-2
x = 17.5
Length of a side of pentagon = 4x - 1
Plug in the value of x
4(17.5) - 1 = 70 - 1 = 69
length of a side of the pentagon = 69

Shawna is making smoothies. The recipe calls for two parts yogurt to three parts blueberry. Shawna wants to make 10 cups of smoothie. Mix how many cups of yogurt and blueberries does Shawna need
Answer:
Shawna needs a mix of 4 cups of yoghurt and 6 cups of blueberries
Step-by-step explanation:
Here, we want to know the number of cups of yoghurt and smoothies Shawna needs to make;
We have 2 parts yoghurt and 3 parts blueberry, so we can say we have a ratio of 2:3
The total number of cups to be made is 10
So the number of cups of yoghurt will be;
2/(2+3) * 10
= 2/5 * 10 = 4 cups
The number of cups of blueberry would be;
3/5 * 10 = 6 cups
So a mix of 4 cups of yoghurt and 6 cups of blueberries is needed by Shawna

What is improper fraction?
An improper fraction is defined as a fraction whose numerator is greater than the denominator. Suppose, x/y is an improper fraction, such that x > y. It is therefore, the improper fraction is always greater than one.
Fractions have two parts, numerator and denominator. If ⅓ is a fraction, then 1 is the numerator, and 3 is the denominator. An improper fraction has a numerator greater than the denominator. For example, 3/2 is an improper fraction.
Given fraction is [tex]6\frac{1}{6}[/tex]
firstly we will multiply 6 by 6 and then we will add 1
(36+1)/6

Step-by-step explanation:
convert the decimal into a fraction
203/50/x = 9/50 / 1/2
simply the complex fraction:
203/50x = 9/25
cross multiply
450x = 5075
divide both sides by 450:
x= 203/18
Answer:
X=11.2778
Step-by-step explanation:
4.06/X=0.18/0.5
cross multiply
0.18×X=4.06×0.5
0.18X=2.03
divide both sides by 0.18
0.18X/0.18=2.03/0.18
it becomes
X=2.03/0.18
X is therefore 11.2778

Which equation could be used to create the graph
4. Factor x2 - 4x – 32.
Answer:
(x - 8)(x + 4)
Step-by-step explanation:
We need to find something that multiplies to 32 and adds up to 4.
The 2 special numbers would be -8 and 4.
-8(4) = -32
-8 + 4 = -4
We then simply write out the factored form:
(x - 8)(x + 4)
Answer: (x+4)(x-8)
Step-by-step explanation:
x^2 - 4x -32 Find two numbers that their product is -32 and their sum is -4. The numbers -8 and 4 will work out because -8 times 4 is -32 and -8 plus 4 is -4.
Now rewrite the whole polynomial as
x^2 +4x -8x -32 Now group them
(x^2 +4x) (-8x -32) Now factor each side
x(x +4) -8(x +4) factor out x+4
(x+4)(x-8)

Answer:
∠ D = 48°
Step-by-step explanation:
Since AC ~ BC then Δ ABC is isosceles and the base angles are equal, thus
∠ B = ∠ C = 69°, then
∠ ACB = 180° - (69 + 69)° = 180° - 138° = 42° ( sum of angles in Δ )
∠ DCE = ∠ ACB = 42° ( vertical angles )
∠ D = 180° - (90 + 42)° = 180° - 132° = 48°
