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

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
find two consecutive integers whose product is 702
2 consecutive integers with the product of 702 are 27 • 26, or since the question doesn’t specify whether it should be positive or negative, it could also be (-27) • (-26)
Final answer:
The two consecutive integers whose product is 702 are found by solving the quadratic equation n² + n - 702 = 0. Factoring the equation leads to the integers 26 and 27.
Explanation:
To find two consecutive integers whose product is 702, we can denote the first integer as 'n' and the second as 'n+1'. Then the equation to represent their product is n(n+1) = 702. To find the value of 'n', we solve the quadratic equation
n² + n - 702 = 0.
Factoring the quadratic equation, we look for two numbers that multiply to -702 and add up to 1. We find that 26 and -27 meet these criteria. So the equation factors to (n + 27)(n - 26) = 0. The two possible values for 'n' are -27 and 26.
The two consecutive integers are 26 and 27 because -27 gives negative integers which do not result in a positive product of 702. Therefore, the two consecutive integers whose product is 702 are 26 and 27.
Stefano had $46 in a bank account that he was not using. Each month
for three months, the bank withdrew ¼ of this amount as a service fee.
How much was left in the account after the last withdrawal?
Final answer:
After three monthly withdrawals of ¼ of the account balance from Stefano's initial $46, he is left with $19.41 in his account.
Explanation:
To calculate how much money Stefano has left in the account after each monthly withdrawal of ¼ of the account balance, we will need to subtract ¼ of the balance three times, once for each month.
Initial amount in Stefano's account: $46
First withdrawal: 1/4 of $46 = $11.50 Stefano's balance after first withdrawal: $46 - $11.50 = $34.50
Second withdrawal: 1/4 of $34.50 = $8.625 Stefano's balance after the second withdrawal: $34.50 - $8.625 = $25.875
Third withdrawal: 1/4 of $25.875 = $6.46875 Stefano's balance after third withdrawal: $25.875 - $6.46875 = $19.40625
After the last withdrawal, Stefano has $19.41 in the account (rounded to the nearest cent).

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.

A Ferris wheel has 20 cars that are equally spaced around the circumference of the wheel. The wheel rotates so that the car at the bottom of the ride is replaced by the next car. By how many degrees does the wheel rotate?
The Ferris wheel rotates ______ ° between successive cars being at the bottom.
Answer:
The Ferris wheel rotates 18° between successive cars being at the bottom.
Explanation:
Angle inside a circle = 360°
No of cars in a Ferris wheel = 20
When the bottom of the ride is replaced by the next car, the angle rotated by Ferris wheel is same as the angle between two consecutive cars towards center of Ferris wheel.
Angle between two consecutive cars of Ferris wheel = 360/20 = 18°
The Ferris wheel rotates 18° between successive cars being at the bottom.
Final answer:
The Ferris wheel rotates by 18 degrees to move from one car to the next in sequence at the bottom of the wheel.
Explanation:
To determine by how many degrees the Ferris wheel rotates when one car is replaced by the next at the bottom, we need to consider the full rotation of the wheel. A full rotation of a circle is 360 degrees. Since there are 20 cars equally spaced around the circumference, we divide 360 degrees by the number of cars to find the rotation angle between successive cars.
The calculation is as follows:
360 degrees / 20 cars = 18 degrees
Therefore, the Ferris wheel rotates by 18 degrees between successive cars being at the bottom of the ride.
Iona's favorite peaches are are $2.50 per pound at the local Farmers Market she bought 3.5 lb of peaches how much did she spend
Final answer:
Iona spent $8.75 on peaches after buying 3.5 pounds at $2.50 per pound at the local Farmers Market.
Explanation:
Iona's favorite peaches cost $2.50 per pound at the local Farmers Market, and she purchased 3.5 pounds of peaches. To calculate the total cost, we multiply the price per pound by the number of pounds purchased:
Total cost = Price per pound × Number of pounds
Total cost = $2.50 × 3.5
Total cost = $8.75
Therefore, Iona spent $8.75 for the peaches at the local Farmers Market.

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.
