Which points are collinear with points A and B ?
The collinear points with A and B are:
- A, B, R
- B, D, T
- C, D, U
- B, S, G (where G is the centroid of AEDC).
In the given pyramid BAEDC, the collinear points with points A and B are determined by the midpoints and the line coming from B.
1. Midpoint of BA is R:
- Points A, B, and R are collinear.
2. Midpoint of BD is T:
- Points B, D, and T are collinear.
3. Midpoint of CD is U:
- Points C, D, and U are collinear.
4. Line coming from B meets at S, the midpoint of AEDC:
- Points A, E, D, C, and B are vertices of the pyramid, and S is the midpoint of the line segment connecting B to the centroid of the base AEDC.
- Therefore, points B, S, and the centroid (G) of AEDC are collinear.
In summary, the collinear points with A and B are:
- A, B, R
- B, D, T
- C, D, U
- B, S, G (where G is the centroid of AEDC).
Solve. T + 23 > 1 t > 24 t > –22 t < 24 t < –22
t + 23 > 1 subtract 23 from both sides
t + 23 - 23 > 1 - 23
t > -22

mary pitches a ball. the initial height is 4 ft and velocity 55 ft per second. when will the ball hit the ground?
Answer:
t = 3.5 sec
Step-by-step explanation:
The equation that represents the position of the ball as a function of time is the following:
[tex]h(t) =P_{o} + V_{o}t+\frac{1}{2}2at^2[/tex]
Where:
[tex]P_{o}[/tex] = Initial position of the ball (4 feet tall)
[tex]V_{0}[/tex] = Initial speed of the ball (55feet / s)
a = acceleration (9.8 [tex]\frac{m}{s^2}[/tex], or in this case 32.16[tex]\frac{ft}{s^2}[/tex])
t = time in seconds
Then we want to know how long it takes to get to the ground, for this we equal h (t) = 0 and clear t.
So:
[tex]0 = 4 + 55t -16.08t ^ 2[/tex]
Solving the second degree equation we have:
[tex]\frac{-b+\sqrt{b ^ 2-4ac}}{2a} \\ \frac{-b-\sqrt{b ^ 2-4ac}}{2a}[/tex]
[tex]\frac{-55+\sqrt{55^2-4 (-16.08) 4}}{2 (-16.08)}= -0.0712\\\frac{-55-\sqrt{55^2-4 (-16.08) 4}}{2 (-16.08)} = 3.492[/tex]
t = -0.071 sec
t = 3.5 sec
We must take the positive solution.
So:
t = 3.5 sec

A standard brick is 3.625 inches wide, 2.25 inches high, and 7.625 inches long. How many bricks could be in a pallet of bricks that measures 4 feet on all sides? (One cubic foot is 12×12×12 cubic inches.)
A. 1,757
B. 1,974
C. 1,709
D. 1,778
Answer: Option D. 1,778
Solution:
Standard brick:
Width: w=3.625 in
Height: h=2.25 in
Length: l=7.625 in
Volumen of one standard brick: v
v=w*h*l
v=(3.625 in)*(2.25 in)*(7.625 in)
v=62.19140625 in^3
Pallet of bricks:
Side: s=4 feet
s=(4 feet)*(12 in / 1 feet)→s=48 in
Volume of a pallet of bricks: V=s^3
V=(48 in)^3
V=110,592 in^3
Number of bricks could be in a pallet: n
n=V/v
n=(110,592 in^3) / (62.19140625 in^3)
n=1,778.252119
n=1,778

Jessica has 1368 baseball cards Thomas has has 1633 who has more baseball cards
Total number of baseball cards Jessica has = 1368 cards.
Total number of baseball cards Thomas has = 1633 cards.
We need to find who has more baseball cards.
We can see 1633 is greater than 1368, because we have hundreds digit in 1633 is 6 and hundreds digit in 1368 is 3.
6 is greater than 3. Therefore 1633 is greater than 1368.
And finally we could say Thomas has more baseball cards than Jessica has.Answer:Thomas
Step-by-step explanation:
1633 > 1368

Yolanda says 105 is the same as 50 because 10x5 equals 50. What was yolanda's mistake
Answer: Yolanda's mistake is that she is assuming 105 is same as 10 x 5 .
Explanation:Here 105 represents a three digit number where 1 is at hundreds place,0 is at tens place and 5 is at once place and it can be written as the product of its factors 5 and 21 i.e 105=5×21 =21+21+21+21+21+21=105(by adding once place and tens place), where as 10×5 represents 5 times number 10 i.e.10+10+10+10+10=50(by adding once place and tens place)
So ,assuming 105 is same as 10 x 5 is her mistake.

What is m∠PTS?
<PTS = <RTQ (vertical angles are equal)
11(y - 10) = 4y - 5
11y - 110 = 4y - 5
7y = 105
y = 15
so
<PTS = 11(15 - 10) = 11(5) = 55
Answer
<PTS = 55°
A cylinder has a volume of 628 cubic inches and a radius of 10 inches. What is the height of the cylinder
Answer:
Height of cylinder = 2 inches
Explanation:
If a cylinder has a base radius r and height h, the volume of cylinder is given by the expression, Volume V = πr²h.
Here given that volume of cylinder = 628 cubic inches = 628 inch³
Radius of base circle = 10 inch.
Substituting in the volume of cylinder equation
628 = π x 10² x h
[tex]h= \frac{628}{\pi *10^2} \\ \\ h=2.00 inches[/tex]
So , height of cylinder = 2 inches
A ferry traveled \dfrac16 6 1 start fraction, 1, divided by, 6, end fraction of the distance between two ports in \dfrac37 7 3 start fraction, 3, divided by, 7, end fraction hour. The ferry travels at a constant rate. At this rate, what fraction of the distance between the two ports can the ferry travel in one hour?
Answer:
The ferry can travel [tex]\frac{7}{18}[/tex] of the distance between the two ports in one hour.
Step-by-step explanation:
A ferry traveled [tex]\frac{1}{6}[/tex] of the distance between two ports in [tex]\frac{3}{7}[/tex] hour.
Suppose, the ferry traveled [tex]x[/tex] of the distance between the two ports in one hour.
So, the equation according to the ratio of "distance" to "time" will be.......
[tex]\frac{\frac{1}{6}}{\frac{3}{7}} =\frac{x}{1} \\ \\ x=\frac{1}{6}\times \frac{7}{3}= \frac{7}{18}[/tex]
Thus, the ferry can travel [tex]\frac{7}{18}[/tex] of the distance between the two ports in one hour.
Alejandro needs to buy bird seed from the local pet store for his parrots. A
10
lb. bag of bird seed costs
$12.55.
The pet store also sells loose bird seed for
$1.49
per pound. The sales tax is already included in these prices. Alejandro wants to buy a
10
lb. bag of bird seed and some loose bird seed. If he has
$20,
how many pounds of loose bird seed can he buy after purchasing the
10
lb. bag?
First take note he only has $20 and the bag he must buy is $12.55. Also the loose seeds are $1.49 per pound.
To solve subtract 12.55 from 20
20-12.55=7.45
So after buying the 10 lb bag he has $7.45 left now divide that by 1.49
7.45/1.49=5
So after buying the 10 lb bag he can also buy 5 lb of the loose seeds!

The temperature decreased overnight by 15.2°C to a temperature of –12.8°C. Suppose t represents the temperature before it decreased.
Which equation can be used to represent this situation?
A.
t – 15.2 = –12.8
B.
t + 12.8 = –15.2
C.
t – 12.8 = 15.2
D.
t – (–15.2) = –12.8
Answer:
Option a
Step-by-step explanation:
Given that temperature originally was t.
It was decreasing continuously overnight.
finally the temperature reading was -12.8 degree C
Given that it decreased by 15.2 degree C
This means original temperature -15.2 = new temperature -12.8
i.e. t-15.2 = -12.8 is the correct equation.
Option a is right.
Verify:
Solve to get t = 15.2-12.8 = 2.4
Hence when 2.4 decreases by 15.2 we get new temperature
= 2.4-15.2 = -12.8
Austin began a repiping job with 26 yards, 2 feet, 5 inches of pipe. When he finished the job, he had 13 yards, 2 feet, 7 inches. How much pipe did he use for the repiping job? Convert the answer to larger units whenever possible.
Answer:
He used 12.944... yards of pipe for the repiping job.
Step-by-step explanation:
We know that, 1 yard = 3 feet and 1 feet = 12 inches.
That means, 1 yard = (3×12) inches = 36 inches.
So, 1 feet = [tex]\frac{1}{3}[/tex] yard and 1 inch = [tex]\frac{1}{36}[/tex] yard.
Thus, 26 yards, 2 feet and 5 inches [tex]=(26+\frac{2}{3}+\frac{5}{36}) yards = 26.805... yards[/tex]
and 13 yards, 2 feet and 7 inches [tex]=(13+\frac{2}{3}+\frac{7}{36}) yards = 13.861... yards[/tex]
So Austin began a repiping job with 26.805... yards of pipe and when he finshed the job, he had 13.861... yards.
So, the length of the pipe he used for the repiping job will be: [tex](26.805...-13.861...) yards = 12.944... yards[/tex]
12 yards, 2 feet, 10 inches

An up-and-coming band has seen a 50% monthly increase in the the number of audience members at their concerts. At the band's first concert, there were 40 people in the audience. If this trend continues, which of the following graphs represents the number of audience members, y, after x months?
We are given that initially there were 40 people in the audience.
And an up-and-coming band has seen a 50% monthly increase in the the number of audience members at their concerts.
The number of audience members is represented by y variable and
Number of months is represented by x variable.
So, the exponential function would be
y= a(b)^x
Where a is the initial value, b is the growth factors.
a= 40 and b= 1+ 0.50 = 1.50.
Therefore,
y= 40(1.50)^x is the exponential function situation.
Let us check some point on the graph.
If we plug x=0, we get initial value 40.
If we pug x=2, we get
y=40(1.50)^2 = 40(2.25) = 90.
Graph C represents y=40 at x=0 and y=90 at x=2.
Therefore, correct option is C option.If you're on Plato the answer would be C

Choose the related addition sentence that shows the commutative property of addition..
A.
4 + 7 = 11
B.
11 – 4 = 7
C.
11 = 7 + 4
D.
8 + 3 = 11
For this case, we have the expression given by:
[tex]a + b = c\\[/tex]
This expression turns out to be generic.
The commutative property of the addition states that the order of the addends does not alter the sum. Thus it is concluded that the previous expression above can be written as:
[tex]b + a = c\\[/tex]
In this way [tex]7 + 4 = 11[/tex], applying the commutative property of the addition, it can be written as:

Mary has a planting pot with a circumference of 92 cm. If a plants' directions state that it must be planted directly in the middle of the pot, what would be the exact measurement? Hint: Find the radius.
24.64 cm
14.64 cm
19.64 cm
22.64 cm
Answer:
14.64 cm
Step-by-step explanation:
this problem is finding radius of a circle from the circumference given.
Circumference of a circle = 2(3.14) r
Using the above we can find one if we know the other. In our case we know circumference and calculate radius.
Circumference = 2(3.14)r= 92 cm
Hence r = 92/2(3.14) = 14.6497cm
apprxoximately 14.64 cm is close to the answer
Hence answer is 14.64 cm.
Answer:
14.64 cm
Step-by-step explanation:
The circumference of a planting pot = 92 cm
To find the measurement of the plant which is planted directly planted in the middle of the pot, we need to find the radius of the planting pot.
We know that the formula of the circumference of a circle is:
Circumference = [tex]2\pi r[/tex]
Therefore, putting the value of the circumference in the formula to get:
92 = 2 x 3.14 x r
r = 92 / (3.12 x 2) = 14.64 cm
Therefore the plant is 14.64 cm long.
