In 2000 the total amount of gamma ray bursts was recorded at 6.4 million for a city. In 2005, the same survey was made and the total amount of gamma ray bursts was 7.3 million. If the Earth can only withstand 1 billion gamma ray bursts, in what year will this become a problem? (Find the year in which the gamma ray bursts is 1 billion.)
In 2000 the total amount of gamma ray bursts was recorded at 6.4 million for a city.
We assume at 2000, t=0.
When t=0 then gamma ray bursts y= 6.4 million. that is (0,6.4)
In 2005, the same survey was made and the total amount of gamma ray bursts was 7.3 million
In 2005 , t= 5
When t=5 then gamma ray bursts y= 7.3 million. that is (5, 7.3)
Frame an equation using (0,6.4) and (5, 7.3)
Use equation y = a(b)^t and solve for a and b
(0,6.4) => [tex]6.4=a(b)^0[/tex] so a= 6.4
(5, 7.3) => 7.3=6.4(b)^5
[tex]\frac{7.3}{6.4} = b^5[/tex]
Now take fifth root on both sides
b= 1.0266
So the equation becomes [tex]y= 6.4(1.0266)^t[/tex]
Now we need to find out t when gamma ray bursts 1 billion
1 billion = 1000 millions
So we replace y by 1000 and we solve for t
[tex]y= 6.4(1.0266)^t[/tex]
[tex]1000= 6.4(1.0266)^t[/tex]
Divide by 6.4 and take ln on both sides
[tex]ln(\frac{1000}{6.4} )= ln(1.0266)^t[/tex]
We move the exponent 't' before ln
[tex]ln(\frac{1000}{6.4} )=t * ln(1.0266)[/tex]
Now divide both sides by ln(1.0266)
[tex]\frac{ln(\frac{1000}{6.4})}{ln(1.0266)} =t[/tex]
t = 192.419
It will take around 192 years
2000+ 192= 2192
In 2192, the gamma ray bursts is 1 billion

Julie is digging a square area in her backyard a for a vegtable garden. If the area is 52 square feet, what is the approximate length of one of her garden?
(a) 6 feet
(b) 7 feet
(c) 8 feet
(d) 9 feet
Answer:
The correct option will be: (b) 7 feet.
Step-by-step explanation:
Suppose, the length of the garden is [tex]x[/tex] feet.
As the shape of the garden is like a square, then the area of the garden will be: [tex](length)^2 = x^2[/tex] feet²
Given that, the area is 52 square feet. So, the equation will be.......
[tex]x^2= 52\\ \\ x=\sqrt{52} = 7.211.... \approx 7[/tex]
So, the approximate length of the garden will be 7 feet.
A 13.9 gallon gas tank is 4/5 full. How many gallons will it take to fill the tank?
It will take 2.78 gallons to fill the remainder of the tank.
13.9 * 4/5 = 11.12 - 11.12 is the amount of gas already in the tank.
13.9 - 11.12 = 2.78 - So, subtract 11.12 from 13.9 and you get your answer.

rubin drew this diagram of his garden.how can you dividethe shape to find the area?
ANSWER
We can divide in to two rectangles as in the attachment.
We then find the area of each rectangle and add together.
The area of the bigger rectangle is
[tex]A_1= 4\times 8[/tex]
[tex]A_1= 32 m^2[/tex]
The area of the smaller rectangle i
[tex]A_2= 4\times 6[/tex]
[tex]A_2= 24 m^2[/tex]
Hence the area of the figure is
[tex]Area=32+24[/tex]
[tex]Area=56 m^2[/tex]
Answer:
Divide it into a square and a rectangle
The area is 56 m^2
Step-by-step explanation:
First, you have to divide the shape to get easier shapes to find the area. We are going to draw a line and we will get a square and a rectangle. This is in the attachment.
We know that to get the area of a square and a rectangle we use the formula:
A=b*h
where
A is the area
b is the base
h is the height
After drawing the line we get a square of 4m each side and a rectangle with b=10 m and h=4m.
Now we get the area of each of the shapes.
Square:
A = 4m * 4m
A = 16 m^2
Rectangle:
A = 10m * 4m
A = 40m^2
Now we add the area of the rectangle and the area of the square to get the total area:
Total Area = 16m^2 + 40m^2
Total Area = 56m^2
Which equation represents the total commission (c) a sales associate receives if he sells 15 laptop computers (l)? What is the total commission if the commission for selling each computer is $39.95?
A. l = 15c; $2.66
B. c = 15l; $2.66
C. c = 15l; $599.25
D. l = 15c; $599.25
Answer : C
the total commission (c) a sales associate receives if he sells 15 laptop computers (l)
Total commission = number of laptops * commission for each laptop
Total commission is c
number of laptops is 15
commission for laptop is l
C = 15 * I
So c= 15l
the commission for selling each computer is $39.95
c= 15l
c = 15 * 39.95 = 599.25
the arena of a tennis corurt is 2808 square feet. find the length of the court if it is 36ft wide
A tennis court is a rectange.
The area of a rectange is equal to length * width.
A = l*w
2808 = l * 36 (Divide both sides of the equation by 36)
L = 78
The area of a 2D form is the amount of space within its perimeter. The length of the court is 78 ft.
What is an area?The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm², m², and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
Given that the arena of a tennis court is 2808 square feet, while the width of the court is 36ft wide. Therefore, the length of the arena can be written as,
Area of court = Length of the court × Width of the court
2808 sq. feet = Length of the court × 36 feet
Length of the court = 2808 ft² / 36 ft
Length of the court = 78 ft
Hence, the length of the court is 78 ft.

If you are solving for "h" here you go.
Simplifying
3(2 + -0.9h) + (-1.3h + -4) = 0
(2 * 3 + -0.9h * 3) + (-1.3h + -4) = 0
(6 + -2.7h) + (-1.3h + -4) = 0
Reorder the terms:

Remove parenthesis around (-4 + -1.3h)
6 + -2.7h + -4 + -1.3h = 0
Reorder the terms:

A coin had a value of $1.17 in 1995. Its value has been increasing at 9% per year. What is the value after 5 years?
P = P₀ (1 + r)ⁿ
= 1.17(1 + 0.09)⁵
= 1.17(1.09)⁵
= 1.17(1.5386)
= 1.80
Answer: $1.80
Note: If you don't know the formula, you could calculate each year.
Year 0: $1.17
Year 1: $1.17 + $1.17(0.09) = $1.2753
Year 2: $1.28 + $1.28(0.09) = $1.3948
Year 3: $1.39 + $1.39(0.09) = $1.5155
Year 4: $1.51 + $1.51(0.09) = $1.6464
Year 5: $1.65 + $1.65(0.09) = $1.7982 which rounds up to $1.80
The value of the coin after 5 years is $188.33.
To find the value of the coin after 5 years, we can apply the compound interest formula. First, convert the initial value of $1.17 to $117 (since we are dealing with percentages). Next, calculate the value after 5 years using the formula: future value = present value × (1 + growth rate)^n. Plugging in the values, we have: future value = $117 × (1 + 0.09)^5 = $117 × 1.6097 = $188.33.

G.o has 3 orange picks for every two green. If there are 25 picks in all, how many picks are orange
15 picks are orange....
Answer:
15 orange picks.
Step-by-step explanation:
Let x represent the number of orange picks.
We have been given that G.o has 3 orange picks for every two green. We are asked to find the number of orange picks, if there are 25 picks in all.
Since there are 3 orange picks for every two green. so there will be 3 orange picks for all 5 (3+2) picks.
We will use proportions to solve our given problem.
[tex]\frac{x}{25}=\frac{3}{5}[/tex]
Upon multiplying both sides of our equation by 25, we will get:
[tex]\frac{x}{25}*25=\frac{3}{5}*25[/tex]
[tex]x=3*5[/tex]
[tex]x=15[/tex]
Therefore, there are 15 orange picks for all 25 picks.
