Answer:
The three collinear poitns are D, A, and E.
Step-by-step explanation:
Collinear points are points that all reside on the same line. Since we are looking for 3 seperate points we need a line with 3 points. There are only 2 lines on the picture and only one has three lines getting you your answer.
Two angles from a liner pair. The measure of one angle is 4 times the measure of the other angle. Find the measure of each angle
Answer:
x = 36 degrees, the smaller angle.
4(36) = 144 degrees, The larger angle.
36 + 144 = 180 degrees.
Cleomenius.
Answer:
x = 36 degrees, the smaller angle.4(36) = 144 degrees, The larger angle.36 + 144 = 180 degrees.
Step-by-step explanation:
(1)adjacent- two non-overlapping angles that share a common vertex and a common side
(2)the non-common sides are opposite rays.
(3)adds up to 180
What is the justification for the step taken from line 2 to line 3?
Answer:
They subtracted 2x from both sides.
Step-by-step explanation:
They removed 2x from each side because in order to find x it will have to be removed on one side. Since 2x - 2x = 0 it is 2x is out of the equation for the right side and on the left side -2x -(-4x) = -6x which means that there is one x variable left in the equation thus making it solvable.
90 + 12 = 6(15 + 12)
The following graph shows a proportionality between y and x in the graph ?
Answer:
3/1 is the ans
Step-by-step explanation:
here y is in 3
and x is in 1
so proportonality will be 3/1
Idk how to solve these
pls show work and explain how to do it
Step-by-step explanation:
1. We can see that the two vertical lines are parallel. Since one angle is 80º, then the other side should be 100º, since the straight line is 180º.
2. If the angle on the right is 80º, then that means the angle with y and 40º add up to 100º.
3. 100º - 40º = 60º.
Our final answer: y = 60º

15+21 distributive property
What is m RMS in the figure below?
RA
P
M
128°
T
A 26
B 38
C 52
D 128
Answer:
Option (B)
Step-by-step explanation:
There are two lines PS and QT intersecting each other at a point M.
It's given that m∠PMT = 128° and m∠QMR = 90°
Since ∠PMT and ∠QMS are the vertical angles so these angles will be equal in measure.
∠PMT = ∠QMS
128° = m∠QMR + m∠RMS
128° = 90° + m∠RMS
m∠RMS = 128° - 90°
m∠RMS = 38°
Therefore, Option (B) will be the answer.

Step-by-step explanation:
Jackson drops a pumpkin off a balcony from
a height of 64 feet. Analyze the time in seconds it takes
for the pumpkin to smash on the ground.
Answer:
t = 1.15 seconds.
Step-by-step explanation:
The pumpkin is dropped from the height of = 64 feet.
Now we have to find the time taken to reach the pumpkin on ground. Use the below formula to find the time taken.
H = ½ gt^2
H = height
g = 9.8 (always contant )
t = time taken.
Now insert all the values in the formula.
H = ½ gt^2
64 = ½ ×9.8× t^2
(64×2) / 9.8 = t^2
t = 1.15 seconds.

Is the number a rational number? Help me out please!
Answer:
first answer
Step-by-step explanation:
Hi, this is correct because repeating decimals are rational numbers.
Rational numbers can be written by a fraction of integers.
If there is a pattern, it means that this is the division of two integers.

Step-by-step explanation:
Which model represents a fraction less than Three-fifths? A circle divided into 5 equal parts. 4 parts are shaded. A circle divided into 5 equal parts. 2 parts are shaded. A circle divided into 5 equal parts. 6 parts are shaded. A circle divided into 10 equal parts. 8 parts are shaded.
Answer:
The correct answer is:
A circle divided into 5 equal parts. 2 parts are shaded.
Step-by-step explanation:
To determine the fraction less than three-fifths, let us convert the word problems into figures and compare the values:
[tex]Three-fifths = \frac{3}{5} = 0.6[/tex]
a) A circle divided into 5 equal parts. 4 parts are shaded (four-fifths)
[tex]Four-fifths = \frac{4}{5} = 0.8\ (more\ than\ three-fifths)[/tex]
b) A circle divided into 5 equal parts. 2 parts are shaded. (two-fifths)
[tex]Two-fifths = \frac{2}{5} = 0.4\ (less\ than\ three-fifhs)[/tex]
c) A circle divided into 5 equal parts. 6 parts are shaded = [tex]\frac{6}{5} = 1.2[/tex] (more than three-fifths)
d) A circle divided into 10 equal parts. 8 parts are shaded [tex]= \frac{8}{10} = 0.8\ (more\ than\ three-fifths)[/tex]
Therefore, the fraction less than three-fifths = A circle divided into 5 equal parts. 2 parts are shaded. (two-fifths)
A circle divided into 5 equal parts. 2 parts so the answer is B

Describe the steps to copy angle CAB∠ C A B.
Answer:
Step-by-step explanation:
Construction: To copy angle CAB.
i. On angle CAB, with center A and any radius; draw an arc to intersect CA at E and AB at F.
ii. Place a divider at EF to copy the angle.
iii. Draw a separate straight line MN of approximate length to AB.
iv. Mark point P on MN. Place the divider with radius EF at P to mark Q.
v. Draw a line LM from M through Q.
vi. Therefore, angle CAB would be equal to angle LMN.
Find and describe the error in the followig work -3(2x+3)=21 -6x+9=21 -6x=12 x=-2
Answer:
-3(2x+3)=21 does not become -6x+9=21 because wrong foiling.
Step-by-step explanation:
When you distribute -3 with 2x+3 you multiply both values by -3.
-3*2x = -6x
-3*3 = -9 <- This is where the error is. It's -9, not +9.

5j+15=12j-13 please solve
Answer:
j=4
Step-by-step explanation:
5j+15=12j-13
Answer: j = 4
Step-by-step explanation:
5j + 15 = 12j - 13
5j = 12j - 28 Subtract 15 from both sides
-7j = -28 Subtract 12j from both sides
j = 4 Divide -7 from both sides
-2, -1, -1, 0, -1, 1, -2, … Find the next 3 numbers in the sequence above. Describe the pattern.
Answer: -2, -1, -1, 0, -1, 1, -2, -1, -1, 0
Step-by-step explanation:
When you are looking at the problem
" -2, -1, -1, 0, -1, 1, -2, … Find the next 3 numbers in the sequence above. Describe the pattern."
you want to observe the pattern, now For example
1, 2, -1, -4 .. and so on
so there is a pattern here if looked at hard enough it goes 1 - 2 = -1 - -3 = -4
when you find the pattern it gets really easy.
Hope this helped!

Step-by-step explanation:
The parking lot at a grocery store has 90 cars in it. 90% of the cars are blue. How many cars are blue?
a 10 cars
b 81 cars
c 810 cars
d 100 cars
Answer:
81 blue cars
Step-by-step explanation:
Total Cars = 90
How much % are blue = 90
=> 90 x 90/100 = How many cars are blue
=> 8100/100 = the number of cars that were blue
=> 81 = cars that were blue.
There 81 blue cars in the parking lot.
The difference of the squares of two positive consecutive even integers is 12. Find the integers. Use the fact that, if x represents an even integer, then x + 2 represents the next consecutive even integer
Answer:
2 and 4.
Step-by-step explanation:
(x+2)^2 - x^2 = 12
x^2 + 4x + 4 - x^2 = 12
4x + 4 = 12
4x = 8
x = 2.
Hence the integers are 2 and 4.
