What is the area of a rhombus if one diagonal is 6 centimeters and the other diagonal is 8 centimeters?
Answer:
24 cm²
Step-by-step explanation:
The area (A) is calculated as
A = [tex]\frac{1}{2}[/tex] product of the diagonals, that is
A = 0.5 × 6 × 8 = 24 cm²

meters Mathieu ran = m*t
Difference in meters per second is the difference in rates= m-e
Number of seconds = time = t
Answer:
this took like forever but there u go
Step-by-step explanation:

meters Mathieu ran = m*t
Difference in meters per second is the difference in rates= m-e
Number of seconds = time = t
Show the Euler-Descartes formula holds for the Great Pyramid of Cheops
Answer:
For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula
Step-by-step explanation:
The great pyramid of Cheops is a square based pyramid therefore we have;
V + F = E + 2
Where:
V = Vertices
F = Faces
E = Edges
Hence, we have for a square pyramid;
V = 5 vertices (One at the peak, and four at the base edges)
F = 5 faces (The four lateral or side faces and the base)
E = 8 edges ( The four lateral edges and the four base edges)
Hence;
5 + 5 = 8 + 2 which proves Euler-Descartes formula.

You have a standard deck of cards. The deck has 52 total cards and contains 4 suits: hearts, clubs, diamonds, and spades. Each suit consists of cards numbered 2-10, a jack, a queen, a king, and an ace.
You select one card at random from the deck. Let A be the event that the randomly selected card is a diamond and let B be the event that the card is a king. Based on this information, answer the following questions.
Answer:
[tex]P(A) = \dfrac{1}{4}\\P(B) = \dfrac{1}{13}\\P(A \cap B) = \dfrac{1}{52}\\P(A/B) = \dfrac{1}{4}\\P(A/B) = P(A)\\[/tex]
A and B are not independent events.
Step-by-step explanation:
Total number of possibilities is 52 (Total number of cards in the deck).
Formula for probability of an event E can be observed as:
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]
For event A, number of cases possible for a card to be diamond = 13
[tex]P(A) = \dfrac{13}{52} \\\Rightarrow P(A) = \dfrac{1}{4}[/tex]
For event B, number of cases possible for a card to be a king = 4
[tex]P(B) = \dfrac{4}{52} \\\Rightarrow P(B) = \dfrac{1}{13}[/tex]
For the event, [tex]A \cap B[/tex], the card is a king and diamond, only one case is possible.
Because there is only one card for king of diamond.
[tex]P(A \cap B) = \dfrac{1}{52}[/tex]
Formula for P(A/B):
[tex]P(A/B) = \dfrac{P(A \cap B)}{P(B)}[/tex]
[tex]\Rightarrow \dfrac{\dfrac{1}{52}}{\dfrac{1}{13}}\\\Rightarrow \dfrac{1}{4}[/tex]
Yes, P(A) is same as P(A/B).
Here, A and B are not independent events because they have a common case i.e. a king is there which is of diamond in the deck.
Answer:
1/4
1/13
1/52
Yes, events a and b are independent events
DVD players are going out of fashion in the modern era. If 400,000 DVD players were sold this year and sales are declining at a rate of 31% per year, how many will be sold 3 years from now?
130,000
131,404
128,000
399,876
Answer:
c
Step-by-step explanation:
Answer:
399,876
Step-by-step explanation:
So, 400,000 DVD sales with a 31% decline means in the first year following, there will be a decline of 124,000 DVDs sold. So we need to take 400,000-124,000 which equals a starting point for your two is 276,000 dvds. Then, add 123,876, which gives you 399,876.
Dr. Barber needs to pay her employees $15.00 an hour. If she has five
technicians and they each worked 25 hours, how much money in total will Dr.
Barber pay all of the technicians?
Answer:
$1,875
Step-by-step explanation:
$15.00 per hour (multiply by hours)
per technician (multiply by technicians)
so: 15x25=375 then 375x5=1,875
Answer:
$1875
Step-by-step explanation:
First, let's find how many hours the technicians worked
She has 5 technicians, and the each worked 25 hours
We can multiply 5 and 25 to find the total number of hours
5*25=125
Now we know that the technicians worked 125 hours altogether. Now, we need to find how much money that is.
They worked 125 hours, and they are paid $15 per hour
We can multiply 125 and 15 to find the cost
125*15=1875
So, Dr. Barber will pay the technicians $1875 in total

Arun’s restaurant bill is $58, and he wants to leave the waiter an 18 percent tip. What will Arun’s total bill be? $10.44 $47.56 $68.44 $76.00
Answer:
$68.44 will be the total bill.
Step-by-step explanation:
18/100 = .18
58 x .18 = 10.44
58 + 10.44 = 68.44
:)
Answer:
It would be 68.44
Step-by-step explanation:
What you do is you multiply 58 by .18. it should come out to 10.44. Once you do that, you add the $58 dollar check with the 10.44 tip and the answer is 68.44!!

Step-by-step explanation:
1. Add 3+7+4+2:
[tex]3+7+4+2=16[/tex]
2. Divide it by 4 because we have 4 numbers being added:
[tex]\frac{16}{4} =4[/tex]
3. Subtract 4 from all numbers:
[tex]4-3=1, 7-4=3, 4-4=0,4-2=2[/tex]
4. Add the differences:
[tex]1+3+0+2=6[/tex]
5. Divide again by 4:

3|2−x|=−6
can someone answer this question for me?? THNX!!!
Answer: the answer is 4
Step-by-step explanation:
3(2−x)=−6
Step 1: Simplify both sides of the equation.
3(2−x)=−6
(3)(2)+(3)(−x)=−6(Distribute)
6+−3x=−6
−3x+6=−6
Step 2: Subtract 6 from both sides.
−3x+6−6=−6−6
−3x=−12
Step 3: Divide both sides by -3.
−3x
−3
=
−12

The three friends drove to a park that had batting cages and pitching machines that tossed the balls to the batter automatically. Rameck took his place, ready to bat. "Keep your hands together," George shouted from the other side of the fence. "Bend your knees a little," Sampson offered. "I've watched the Yankees for years," Rameck said, ignoring both of them. "Baseball is easy!” The machine pitched the first ball. Rameck swung with a powerful twist. He missed. The second ball erupted from the machine. Rameck swung again. He missed it by a mile. A third ball came. He swung and missed that one, too. The balls kept coming. Rameck kept swinging. And missing. —We Beat the Street, Sampson Davis et al, Using the drop-down menus, identify the correct sequence of events. First: Second: Third:

Find the GCF for each pair of monomials. 1. 14n2, 35n4 2. 21n3, 18n2 3. 7n2, 9
Answer:
[tex](1)7n^2\\(2)3n^2\\(3) 1[/tex]
Step-by-step explanation:
(1) [tex]14n^2, 35n^4[/tex]
[tex]14n^2=2 X 7 X n^2\\35n^4=5 X 7 Xn^2Xn^2\\$Therefore, the GCF of 14n^2$ and 35n^4$ is 7Xn^2=7n^2[/tex]
(2)[tex]21n^3, 18n^2[/tex]
[tex]21n^3=3 X 7 X n^2 X n\\18n^2 =3 X 6 X n^2\\$Therefore, the GCF of 21n^3$ and 18n^2$ is 3Xn^2=3n^2[/tex]
(3) [tex]7n^2, 9[/tex]
The two terms are co-prime. Therefore their GCF is 1.
