1521 orange trees are planted in a garden in such a manner that there are as many trees in a row as there are rows in the garden. The number of trees in each row is
Answer: 39
Step-by-step explanation:
Total number of orange trees = 1521
Note :
There are as many trees in a row as there are rows in the garden.
Therefore :
Number of rows in the garden = number of trees in a row
Let the number of rows in the garden = y
Hence, the number of trees in a row also = y
Total number of trees in the garden = number of trees in a row × number of rows in the garden
Total number of trees in the garden = y × y
1521 = y × y ; 1521 = y^2
y = √1521
y = 39
Answer:
no.f trees in each row =39Step-by-step explanation:
Total number of orange trees = 1521
Note :
There are as many trees in a row as there are rows in the garden.
Therefore :
Number of rows in the garden = number of trees in a row
Let the no.f trees in each row =x
let the no.f rows=x
therefore total no.f trees =x raised to 2
x raised to 2 =1521
therefore x=39
there fore no.of rows =39
no.f trees in each row =39A canvas shopping bag has a mass of 600 grams. When 5 cans of equal mass are put into the bag, the filled bag has a mass of 4 kilograms. What is the mass of each can in grams?
Answer:
Mass of each can = 680 grams
Step-by-step explanation:
Mass of a canvas shopping bag = 600 grams Or [tex]\frac{600}{1000}[/tex] Kilograms
= 0.6 Kilograms
Let the mass of each can = w Kilograms
Then the mass of 5 cans = 5w Kilograms
Total mass of the bag when these cans were kept in the bag = 4 Kilograms
(5w + 0.6) = 4
5w + 0.6 - 0.6 = 4 - 0.6
5w = 3.4
w = [tex]\frac{3.4}{5}[/tex]
= 0.68 Kilograms
= [tex]0.68\times 1000[/tex]
= 680 grams
Therefore, mass of each can = 680 grams

Please help!! Urgent! Due soon! - A bedroom is initially squat-shaped with each side x feet long. The room is then expanded so that the length of the room is increased by 3 feet, and the width increased by 4 feet. Choose the expression which represents how much bigger the area of the new bedroom is than the old bedroom.
Answer:
The second one; x²+7x+12
Step-by-step explanation:
So, since the beginning lengths of the square is x and x, the area of the square is x².
But then, you add 3 to one length, so that side is now (x+3), and then you add 4 to the width, so that is now (x+4).
Finally, you would multiply them together to get the equation you would use to find the new area.
For this, you would cross-multiply everything together; the x in the length by the x in the width, the x in the length by the 4 in the width, the 3 in the length by the x in the width, and then the 3 in the length by the 4 in the width. Now, all you have to do is add all of these together to get your answer.
Here's the work:
[tex](x+3)(x+4)\\x^{2}+3x+4x+12\\x^{2}+7x+12[/tex]

Elana is programming a video game. She needs to simulate the power up that the player gets when they reach a certain level. The computer can run a program to return a random integer between 1 - 100. Elana wants the best power up to be rewarded 15% of the time. Explain how Elana can use the computer to simulate the player getting the best power up at least 2 out of 3 times
Answer:
You have to define when the power should be pushed up using the 'For' statement and let an impulse be sent to the CPU to increase power by 15%
Step-by-step explanation:
We use certain functions in writing computer programs.
For the 'For' statement ; we can define conditions. First Elana would define at what point does she want the player power to get the best power.
For example if she defines that when the player has played for 2hours return an integer 1 for instance.
This value returned will now send a pulse to the CPU to increase its power to 15%.
If the player plays for further 1hour she can define the count to be 10 and so send another pulse to the CPU to increase the processing power by additional 15%

2-4(3x-y)=8(4-y)-39x and 8(4-y)-39x=6(y-x)
Answer:
X = -(146/123) , Y = 21/41
Step-by-step explanation:
2-4(3x-y) = 8(4-y)-39x2-12x-4y = 32-8y-39x
39x-12x+8y-4y = 32-2
27x+4y = 30
27x+4y-30 = 0
8(4-y) -39x = 6(y-x)32-8y-39x = 6y-6x
32-8y-6y-39x+6x = 0
-33x-14y+32 = 0

A delivery service claims that orders arrive before noon 90% of the time. If Amy uses the delivery service 20 times, how many times can she predict the deliveries will arrive before noon? Is the claim accurate if her packages arrive after noon 4 times?
Answer:
They claim that 90% of the times, the orders arrive in time.
Then, out of N orders, (90%/100%)*N of them will arrive in time.
Here we have that N = 20
then the number that arrives in time is:
(90%/100%)*20 = 18
Now, experimetally we see that 4 times her packages arrived after noon (so 16 times the packages arrived in time), so we can calculate the experimental percentage as:
(X/100%)*20 = 16
X = (16/20)*100% = 80%
so the percentages doesn't match, so it the claim is not really accurate, but this is a small sample, so if the number of times that she uses the delivery increases, we may see that the experimental percentage gets closer to the claimed percentage.

Five times the sum of a number and 3 is the same as 3 times the difference of twice the number and 1.
What is the number?
Answer:
12
Step-by-step explanation:
5(x+3) = 3(2x-1)
5x+15 = 6x-3
15-3 = 6x-5x
12 = x
x = 12
The number should be 12.
Given that,
Let us assume the number be x.Five times the sum of the number & 3 should be the same because 3 times is the difference of the twice of the number and 1.Based on the above information, the following equation should be made:
5(x+3) = 3(2x-1)
5x+15 = 6x-3
15-3 = 6x-5x
12 = x
x = 12
Therefore we can conclude that the number is 12.
