Answer:
13.4 grams of a 120 gram sample will remain radioactive after 30 minutes.
Step-by-step explanation:
Given : A radioactive substance has a decay rate of 0.073 per minute.
To find : How many grams of a 120 gram sample will remain radioactive after 30 minutes?
Solution :
Using decaying formula,
[tex]y(t)=y_o e^{-rt}[/tex]
Where, [tex]y_o=120[/tex] is the initial amount
r=0.073 is the decay rate
t=30 minute is the time
Substitute the value in the formula,
[tex]y(30)=120\times e^{-0.073\times 30}[/tex]
[tex]y(30)=120\times e^{-2.19}[/tex]
[tex]y(30)=120\times 0.1119[/tex]
[tex]y(30)=13.428[/tex]
[tex]y(30)=13.4[/tex]
Therefore, 13.4 grams of a 120 gram sample will remain radioactive after 30 minutes.
Answer:
13.4
Step-by-step explanation:
Substitute the given values into the formula: A(t)=Pert. Where P is the initial mass, r is the rate of decay, and t is time. Note, the rate is negative because we are finding the rate of decay.
A=120e−(0.073)(30)≈13.4
So, about 13.4 grams will remain after 30 minutes.
When two pipes fill a pool together, they can finish in 5 hours. If one of the pipes fills half the pool then the other takes over and finishes filling the pool, it will take them 18 hours. How long will it take each pipe to fill the pool if it were working alone?
The pipes can fill the pool individually in 16 and 20 hours respectively, by solving the simultaneous equations: 1/x + 1/y = 1/5 and 1/2x + 1/2y = 18.
Explanation:Let's assume one pipe can fill the pool in x hours, while the other pipe can fill it in y hours. When the two pipes work together, they complete one job in 5 hours, which can be expressed as 1/x + 1/y = 1/5.
When each pipe fills half the pool, it takes 18 hours. Since each of them is doing half the work, this can be represented as 1/2x + 1/2y = 18.
To solve these simultaneous equations, it is best to use the substitutive method. We can set the two equations equal to each other to get x = 36 - y. Plugging this into the first equation and solving for y, we find y = 20. Substituting y back into the equation x = 36 - y, we find x = 16.
So, one pipe could fill the pool alone in 16 hours, while the other could do it in 20 hours.

The first pipe would take approximately 6.92 hours to fill the pool if it were working alone, and the second pipe would take 18 hours to fill the pool if it were working alone.
Let's assume that the first pipe can fill the pool in x hours, and the second pipe can fill the pool in y hours.
When the two pipes fill the pool together, they can complete the job in 5 hours. So, their combined rate of work is 1/5 of the pool per hour.
When the first pipe fills half the pool, it takes over for the second pipe, which then finishes filling the pool. This entire process takes 18 hours. So, the first pipe fills half the pool in 18 hours, which means that its rate of work is 1/18 of the pool per hour.
Using the concept of work done, we can set up the following equation:
1/x + 1/y = 1/5 (equation 1)
1/y = 1/18 (equation 2)
Solving the equations simultaneously, we can find the values of x and y:
From equation 2, y = 18 hours.
Substituting the value of y in equation 1, we get:
1/x = 1/5 - 1/18 = (18 - 5)/90 = 13/90.
Therefore, x = 90/13 hours.
So, the first pipe would take approximately 6.92 hours to fill the pool if it were working alone, and the second pipe would take 18 hours to fill the pool if it were working alone.

A group of students made trees out of paper for a scene in a school play. The trees are shaped like square pyramids. 2 ft How much paper will it take to make each tree, including the bottom?
Answer:
Step-by-step explanation:
The area of a triangle is base*height/2
So one triangle is 2*4/2=4
Multiplied by 4 sides, 4*4=16
Finally the base is a square, so 2*2=4
Therefore the entire shape is 16+4=20 square feet
The amount of paper it will take to make each tree, including the bottom is 20 ft²
How to find the surface area of some object?Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.
Surface area of paper tree = sum of areas of those 4 slant standing triangles + area of base
Area of each of those 4 triangles are same (assuming they're symmetric).
Each triangle has height of 4 ft and base of 2 ft. (the base is a square of side length 2 ft).
Thus, we get:
Area of 4 triangles = 4(area of each tree ) = [tex]4\left (\dfrac{1}{2} \times \text{base} \times \text{height}\right) = 4\left (\dfrac{1}{2} \times 2 \times 4\right) = 16 \: \rm ft^2[/tex]
Area of square base = [tex]\text{side}^2 = 2^2 = 4 \: \rm ft^2[/tex]
Thus, we get:
Surface area of paper tree = 16 + 4 = 20 ft²
Thus, the amount of paper it will take to make each tree, including the bottom is 20 ft²

Determine the intercepts of the line Y+1=3(x-4)
ANSWER
y-intercept:
(0,-13)
x-intercept:
[tex](4 \frac{1}{3} ,0)[/tex]
EXPLANATION
The given line has equation
[tex]y + 1 = 3(x - 4)[/tex]
At y-intercept , x=0.
This implies that;
[tex]y + 1 = 3(0 - 4)[/tex]
[tex]y = - 12 - 1[/tex]
[tex]y = - 13[/tex]
The y-intercept is
(0,-13).
At x-intercept y=0,
This implies that;
[tex]0+ 1 = 3(x - 4)[/tex]
[tex] \frac{1}{3} = x - 4[/tex]
[tex] \frac{1}{3} + 4 = x[/tex]
[tex]4 \frac{1}{3} = x[/tex]
The x-intercept is
[tex](4 \frac{1}{3} ,0)[/tex]
Answer:
x-intercept = [tex]\frac{13}{3}[/tex]
y-intercept = [tex]-13[/tex]
Step-by-step explanation:
We are given the following equation of a line and we are to find the x and y intercepts for it:
[tex] y + 1 = 3 ( x - 4 ) [/tex]
In order to find the x-intercept, we will substitute 0 in place of y to get:
[tex] 0 + 1 = 3 ( x - 4 ) \\\\ 1 = 3 x - 12 \\\\ 3 x = 1 + 12 \\\\ x = \frac { 13 } { 3 } [/tex]
And to find the y-intercept, we need to substitute 0 in place of x:
[tex] y + 1 = 3 ( 0 - 4 ) \\\\ y + 1 = -124 \\\\ y = - 12 - 1 \\\\ y = - 13 [/tex]
So the x-intercept is [tex]\frac{13}{3}[/tex] while the y-intercept is [tex]-13[/tex].

Retro Rides is a club for owners of vintage cars and motorcycles. Every year the club gets together for a ride. This year, 38 vehicles participated in the ride. The total number of tires of all the vehicles was 104. Assuming each car has 4 tires and each motorcycle has 2 tires, how many each of cars and motorcycles participated in the ride?
A. 18 cars; 20 motorcycles
B. 14 cars; 24 motorcycles
C. 11 cars; 27 motorcycles
D. 16 cars; 22 motorcycles
Answer: OPTION B
Step-by-step explanation:
Let's call:
c: the number of cars.
m: the number of motorcycles.
Based on the given information, you can set up the following system of equations:
[tex]\left \{ {{c+m=38} \atop {4c+2m=104}} \right.[/tex]
You can solve it by the Elimination method:
- Multiply the first equation by -4.
- Add both equations to cancel out the variable "c".
- Solve for "m":
[tex]\left \{ {(-4)(c+m)=38(-4)} \atop {4c+2m=104}} \right.\\\\\left \{ {-4c-4m=-152} \atop {4c+2m=104}} \right.\\-------\\-2m=-48\\m=24[/tex]
(24 motorcycles)
- Substitute m=24 into any of the original equations ans solve for "c". Then:
[tex]c+24=38\\c=38-24\\c=14[/tex]
(14 cars)
The answer is:
Option B.
[tex]Cars=14\\Motorcycles=24[/tex]
Why?We know that the total of tires of all the vehicles was 104, and there were 38 vehicles with 4 tires and motorcyles with 2 tires, so, we can calculate how many cars and motorcyles participated in the ride using the following equation:
Let x be the cars and y be the motorcyles, so:
[tex]x+y=38[/tex]
and,
[tex]4x+2y=104[/tex]
So, isolating x in terms of y from the first equation, we have:
[tex]x=38-y[/tex]
Then, substituting "x" into the second equation we have:
[tex]4(38-y)+2y=104\\152-4y+2y=104\\152-2y=104\\2y=152-104\\2y=48\\y=\frac{48}{2}=24[/tex]
Now, substituting "y" into the first equation, we have:
[tex]x+24=38[/tex]
[tex]x=38-24=14[/tex]
So, there were a total of 14 cars and 24 motorcycles in the ride.

One 8-oz serving each of coffee, energy drink, and soda contains 199 mg of caffeine. One serving of coffee has 11 mg more caffeine than two serving of soda. One serving of energy drink contains 33 less caffeine than one serving each of soda and coffee. Find the amount of caffeine in one serving of each beverage
Answer:
soda = 35mg
coffee = 81mg
energy = 83mg
Step-by-step explanation:
coffee + energy + soda = 199
coffee = 11 + (2 * soda)
energy = (soda + coffee) - 33
(11 + (2 * soda)) + ((soda + (11 + (2 * soda))) - 33) + soda = 199
11 + 2s + s + 11 + 2s - 33 + s = 199
22 + 6s - 33 = 199
-11 + 6s = 199
6s = 210
s = 35
soda = 35mg
c = 11 + 2s
c = 11 + 2(35)
c = 11 + 70
c = 81
coffee = 81mg
e = s + c - 33
e = (35) + (81) - 33
e = 116 - 33
e = 83
energy = 83mg
Final answer:
One serving of soda contains 35 mg of caffeine, one serving of coffee contains 81 mg of caffeine, and one serving of energy drink contains 83 mg of caffeine.
Explanation:
Let's solve this problem step by step:
Let's assume the amount of caffeine in one serving of soda is x mg. Therefore, the amount of caffeine in two servings of soda is 2x mg.According to the information given, one serving of coffee has 11 mg more caffeine than two servings of soda. So, the amount of caffeine in one serving of coffee is 2x + 11 mg.The information also states that one serving of energy drink contains 33 mg less caffeine than one serving each of soda and coffee. Therefore, the amount of caffeine in one serving of energy drink is (x+2x + 11) - 33 mg.To find the value of x, we can set up an equation:
(x) + (2x + 11) + [(x+2x + 11) - 33] = 199Simplifying the equation:
6x + 22 - 33 = 199Combine like terms:
6x - 11 = 199Add 11 to both sides:
6x = 210Divide both sides by 6:
x = 35Therefore, one serving of soda contains 35 mg of caffeine. Substituting this value into the previous equations:
One serving of coffee contains 2(35) + 11 = 81 mg of caffeine.One serving of energy drink contains 35+(2(35) + 11) - 33 = 83 mg of caffeine.Solve these equations. Show solutions on a number line. |x−12| =4

plz give brainliesttttt
Final answer:
The area of a triangular poster with a base of 2 1/2 feet and a height of 1 3/4 feet is calculated using the formula A = 1/2 × base × height, resulting in an area of 2.1875 square feet.
Explanation:
To find the area of a triangle, we use the formula A = ½ × base × height. Given that the base of the triangle is 2 1/2 feet (which is 2.5 feet when converted to a decimal) and the height is 1 3/4 feet (which is 1.75 feet in decimal), we can calculate the area as follows:
A = ½ × base × height
A = ½ × 2.5 ft × 1.75 ft
A = ½ × 4.375 ft²
A = 2.1875 ft²
Therefore, the area of the poster is 2.1875 square feet.
The number of coins Jada will have on the eighth day, if Jada starts with one coin and the number of coins doubles every day. (She has two coins on the first day of the doubling.
Answer:
256 Coins
Step-by-step explanation:
On the first day, Jada starts with one coin, so all you have to do here is multiply it by 2.
Day 1: 2 coins
Day 2: 2 x 2 = 4 coins
Day 3: 4 x 2 = 8 coins
Day 4: 8 x 2 = 16 coins
Day 5: 16 x 2 = 32 coins
Day 6: 32 x 2 = 64 coins
Day 7: 64 x 2 = 128 coins
Day 8: 128 x 2 = 256 coins
Hope this helps! Just message me if you have more questions or need more help! :)
The number of coins that Jada will have after 8 days is; 256 coins
How to solve geometric sequence?
We are told that on the first day, Jada starts with one coin and that the number of coins doubles each day. Thus;
Day 1: She has 2 coins
Day 2: She has 2 * 2 = 4 coins
This follows a geometric pattern 2ⁿ
where n is number of days
Thus, for 8 days, she will have; 2⁸ coins = 256 coins
