Answer: calculations in seconds (or calculations in seconds)
Step-by-step explanation:
The complete exercise is: "A certain computer can perform 10^5 calculations per second. How many calculations can it perform in 10 seconds".
You need to analize the information provided in the exercise in order to solve it.
Let be "x" the number of calculation a certain computer can perform is ten seconds.
According to the exercise this computer can perform calculations in second. Then, in order to calculate the amount of calculattion it performs in seconds, you can set up the following proportion:
Now, you need to find the value of "x".
To solve for "x" you can multiply both sides of the equation by .
Then, you get:
Therefore, the computer can perform calculations in seconds (or calculations in seconds)

A party had 4 2/3 pizzas left. If three people split what is left, how much pizza does each person get
Answer:
1 1/2 each (4 1/2 altogether) and 4/25 will be left
Step-by-step explanation:
4 2/3 = 4.66
4.66÷3= 1.5
1.5x3= 4.5
4.5= 4 1/2
4.66-4.5= 0.16
0.14=4/25

In the diagram below, what are AC and BC?
Answer:
54 degrees
Step-by-step explanation:
a to c is 45 degrees, and b to c is about 9, so add them together and get 54
Answer:
Step-by-step explanation:
This can be solved using the law of sines.
First find angle b which is 180 - (30 + 45) = 180 -75 = 105°
[tex]\frac{sin C}{c}[/tex] = [tex]\frac{sin B}{b}[/tex]
[tex]\frac{sin 45}{10}[/tex] = [tex]\frac{sin 105}{b}[/tex]
Cross multiply at this point
sin 45 (b) = sin 105 (10)
.707106b = .96592 (10)
.707106b = 9.6592
divide both sides by .707106
b = 13.66 this is the length of AC
Next solve for BC which is a in the equation.
[tex]\frac{sin c}{c}[/tex] = [tex]\frac{sin A}{a}[/tex]
[tex]\frac{sin 45}{10}[/tex] = [tex]\frac{sin 30}{a}[/tex]
Cross mulitply
sin 45 (a) = sin 30 (10)
.707106 a = .5 (10)
.707106 a = 5
divide both sides by .707106
a = 7.07 which is segment BC
so AC = 13.66 and BC = 7.07

Are the ratios
25/45
and
15/27
proportional? Explain.
Answer:
Yes
Step-by-step explanation:
First ration we will divide by 5 (both numbers) and second one by 3 (again both numbers).
First ratio becomes (25:5)/(45:5) = 5/9
Second ratio becomes (15:3)/(27:3) = 5/9
Since we can simplify them in that way that both are the same that means they are proportional.
because when we make them smaller like 25/45 divide by 5 and 15/27 divide by 3 it forms 5/9
Answer:
Yes
Step-by-step explanation:
If you divide 25/45 by 5 you get 5/9
Then you divide 15/27 by 3 you also get 5/9
Since both are equal to 5/9 they are proportional.

Answer: The last option. 96/27
Step-by-step explanation:
Volume of the mini cube = 1/3 x 1/3 x 1/3 = 1/27
Volume of the big boi cube = 1/27 x 96 (There are 96 pieces so the volume is clearly 96 x the volume of the mini cube)
= 96/27 or the last option.

A fair coin is tossed three times. What is P(tossing at least two tails)?
A: one eighth
B: one fourth
C: three eighths
D: one half
Answer:
one eighth
Step by step explanation:
Let us mark H for Heads and T for Tails.
The coin is flipped three times; the total
number of outcomes = 2 * 2 * 2 = 8 .
Sample Space (| Omega|)=\ (H, H, H), (H, H, T) ,(H,T,
H ),(H,T,T),(T,H,H),(T,H,T),(T,T,H),(T,T,T)\
= 8
Let X be the probability of getting all tails: X
= \{(T, T, T)\}
=> |X| = 1
P(X) = IXI/IQI = 1/8.
Thus, the probability of flipping a coin three times and getting 3 tails is 1/8.
Answer:
D: one half
Step-by-step explanation:
You want the probability of tossing at least two tails when a fair coin is tossed 3 times.
OutcomesThe outcomes from the tosses will be one of ...
TTT, TTH, THT, THH, HTT, HTH, HHT, HHH
Of the 8 possible outcomes, the 4 that are highlighted have at least 2 tails.
D: The probability of tossing at least 2 tails is 4/8 = 1/2.

Answer:the hat was 14$
Step-by-step explanation: count the money then count the money on the other side see how much money is taken away and there you go that is how much it was
X = $14
Paul starts out with $2. All that you have to do is subtract $6 the amount he has after buying the hat, from $20.
$20 - $6 = $14
or
$20 - X =$6 (in the end you would find out x = 14)

The village shop is selling 9 cans of red beans for $4.32. The same beans are sold for 7 cans for $4.20 at the mini mart. Which place has the better price? (step by step explanation please?)
Answer:
9 cans for $4.32
Step-by-step explanation:
if you divide the number of cans by the total amount, you get:
9 can for $4.32: 0.48 cents (4.32 divided by 9)
7 cans for $4.20: 0.6 cents (also known as 0.60) (4.20 divided by 7)
Answer:
The village shop
Step-by-step explanation:
Here's why
If we do a little math here
The village shop is selling 9 cans for $4.32. Let break this down
4.32 / 9 = .48
The village shop is selling its cans at 48 cent a piece
The mini mart is selling 7 cans for $4.20 which equals out to 60 cent per can.
4.20 / 7 = .60
Therefore per can the village shop is cheaper in this situation because if we added two more cans to the mini mart then our price will be $5.40
60 x 9 = 540
Hope this can help

10./Check for Reasonableness A store manager instructs his employees to mark up all items by 30%. A store clerk puts a price tag of $30 on an item that the store bought for $27. As an employee, you notice that this selling price is incorrect. a. Find the correct selling price. Round to the nearest dollar. b. What was the clerk's likely error?
Answer:
Therefore, the selling price of the item is $35.1. Also, the clerks didn't put enough of the amount up too.
Step-by-step explanation:
Find out the selling price.
To prove
As given
A store manager instructs his employees to mark up all the items by 30%. An item that the store bought for $27.
30% is written in the decimal form.
= 0.30
30% of the $27 = 0.30 × 27
= $8.1
Selling price of the item = Original price of item + 30% of the $27
= $27 + $8.1
= $ 35.1
given 33.8 × 2.5 find the product
a= 8.45
b= 84.5
c= 66.4
d= 69.29

Farmer Bob's son built a track to walk his pet pig. The track goes around the pig pen. The pig pen is 12 feet long and 20 feet wide. If the pig walks all the way around the track, how many feet did he walk?
Answer:
64 ft
Step-by-step explanation:
The pig walked the perimeter of the rectangle whose dimensions are 20 ft and 12 ft.
Use the perimeter formula of a rectangle.
2(l + b) = 2(20 + 12) = 64ft

x3+y3+z3=k, with k being all the numbers from one to 100, is a Diophantine equation that's sometimes known as "summing of three cubes. help please :'}
Answer: (It took over a million computing hours to solve the solution)
Step-by-step explanation: Hello! Do you have to find k? If you do, then it is supposed to be the hardest math problem solved only by computers. I do not know how to solve it if you have to, but the answer is x3 + y3 + x3 = 42/33. Scientists tested all possible integers from 1-100 and they found that only 42 and 33 worked. 42 is the correct answer by computers. Hope this helps!
