In science class, a student is measuring the temperature of a solution in science experiment. The solution
started at -3.4 degrees. After two minutes the temperature had increased 12.4 degrees. After a few more
minutes, the temperature decreased 20.4 degrees. After one more minute the temperature increased by
3.2 degrees. What is the final temperature?
Answer:
-11.8
Step-by-step explanation:
Given:
-3.4 to 12.4 increased (difference = 15.8)
12.4 to 20.4 decreased (difference = 8)
20.4 to 3.2 increased (difference = 17.2)
To find:
Final temperature.
Solution:
As we noticed, this is a pattern of increase, decrease, increase... (and so on and so forth). From this alone, we have gotten the clue that the temperature is going to decrease. But here is the thing, How far will it decrease?
Use the difference of the starting result to find the ending result.
3.2 - 15
= -11.8
Therefore, the final temperature is -11.8.

Answer for brainiest
Answer:
x=72°
Step-by-step explanation:
We know angles around a point equals 360°
Therefore,
(2x-61)°+(x-11)°+3x°=360°
2x-61+x-11+3x=360°
Collect like terms,
2x+x+3x-61-11=360°
6x-72°=360⁰
Evaluate;
6x=360°+72°
6x=432°
Divide both sides by 6
x=72°
A cheerful teen willing to help,
please mark BRAINLIEST,
stay salty...
Answer:
x = 72°
Step-by-step explanation:
there is a total of 360 degrees in a circle
we know we can add the angle measures shown and set it equal to 360
3x + (x-11) + (2x-61) = 360
combine 'like terms':
6x + (-11) + (-61) = 360
6x + (-72) = 360
6x = 432
x = 72
Check:
[2(72)-61] + (72-11) + 3(72) should equal 360
(144-61) + 61 + 216 = 360
83 + 61 + 216 = 360
360 = 360
. The sum of infinity of G.S is 15, 1st term is 3 then the common ratio is.
Step-by-step explanation:
We know ,
=> Sum = a / 1 - r
=> 15 = 3/1-r
=> 15 - 15r = 3
=> 15r = 18
=> r = 18/15
=> r = 6/5

A pyrotechnician plans for two fireworks to explode together at the same height in the air. They travel at speeds shown below. Firework B is launched 0.25 s before Firework A. How many seconds after Firework B launches will both fireworks explode?
Answer:
3.25 seconds after B launches
Step-by-step explanation:
In the 0.25 seconds before A launches, B will have traveled ...
distance = speed · time
distance = (240 ft/s)(0.25 s) = 60 ft
The speed of A is 20 ft/s faster, so will close that 60 ft gap at the rate of 20 ft/s. It will take ...
time = distance/speed
time = 60 ft/(20 ft/s) = 3 s
The fireworks will be at the same height 3 seconds after A is launched. That is 3.25 seconds after B is launched.
_____
Additional comment
Their heights will be (3 s)(260 ft/s) = 780 ft = (3.25 s)(240 ft/s).
your family have decided to paint your room. It took 1/2 hour to paint 1/8 of your room. How long will it take to paint your whole room?
Answer:
4 hours
Step-by-step explanation:
In 6 hours, J paints 1 room
So, in 1 hour, J paints 1/6 th of the room
Using similar logic, in 1 hour, T paints 1/12 th of the room.
Working together in one hour, they paint (1/6+1/12) th =1/4 of the room.
1/4 of the room is painted in 1 hour
So, 1 room is painted in 1 1/4=4 hours

Need help I got 23,294 as the answer but it’s not an option please explain how you got the answer.
Answer:
A
Step-by-step explanation:
Calculation seems correct to me, with d the distance and h the height of the plane, and i got the same value. Closest value is A tho, so i'd stick with it.
If you want to be pedantic about it, you can always divide the heigth by each value, and get the inverse tangent of each value. With A you get 17.995 which seems the best value you get
A file that is 249 megabytes is being downloaded. If the download is 15.7% complete, how many megabytes have been downloaded? Round your answer to the
nearest tenth ?
Answer:
39.1 megabytes
Step-by-step explanation:
Percentages are out of a hundred, so 15.7% is 15.7 out of 100, aka 15.7/100, which is 0.157.
Now, you just need to multiple this number by 249 megabytes to get 0.157 * 249 = 39.093 which rounds to 39.1

A gardener makes a new circular flower bed. The bed is ten feet in diameter. Calculate the circumference and the area of the circular flower bed
Answer:
C=78.5
Step-by-step explanation:
C=πr²
r=1/2 of diameter
π=3.14
C=π5²
C=78.5
The circumference and the area of the circular flower bed are 31.4 feet and 78.5 square feet respectively.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle).
It is given that:
A gardener makes a new circular flower bed. The bed is ten feet in diameter.
D = 10 feet
The radius r = D/2 = 10/2 = 5 feet
A = πr²
π = 3.14
A = π(5)²
A = 78.5 square feet
The circumference:
C = 2πr
C = 2(3.14)(5)
C = 31.4 feet
Thus, the circumference and the area of the circular flower bed are 31.4 feet and 78.5 square feet respectively.

3. A train set costs $120.00. Find the discount if it is on sale for
30% off.
Answer:
36
Step-by-step explanation:
To find the discount, you will need to find 30% of $120, so you will need to do:
120*0.3=36
Also, if you were asking for the COST if it was 30% off, it would be 84 as 120-36=84.

A playground is rectangular with a length of 78 miles. If the area of the playground is 820 square miles, what is its width? Input your answer as a fraction.
Answer:
10.5, [tex]10\frac{1}{2}[/tex], or [tex]\frac{21}{2}[/tex]
Step-by-step explanation:
To solve, you can use a variable (x) to represent the width.
The equation for area is A=L×W
So the Area is 820 and the length is 78.
820= 78w
Isolate the variable to solve.
w=10.5128....
If you round, it will be 10.5
10.5 as a fraction is [tex]10\frac{1}{2}[/tex] or [tex]\frac{21}{2}[/tex]

Mrs. Thomas is designing a rectangular pool for her backyard. The width of the pool is 7
feet shorter than twice its length. The perimeter of the pool is 75 feet. Write the equation to
represent the length of the pool
(1 Point)
Answer:
For the first one , the answer is 15 , the equation is 75=2f+2(2f-7.5)
For the Callie question , the answer is 20 , the equation is 110=2f+2(2f-5)
The third answer is 23 and the equation is 144=2(2w+3)+2w
Step-by-step explanation:
The length of the pool is 15 feet and the width is 23 feet.
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
Let L be the length of the pool.
According to the given information, the width of the pool is (2L - 7) feet.
The perimeter of a rectangle is the sum of all four sides, so we can write the equation:
2L + 2(2L - 7) = 75
Simplifying this equation:
6L - 14 = 75
6L = 89 + 14
L = 89/6
L = 14.833 ≈ 15
So the length of the pool is 15 feet and the width is (2 × 15 - 7) = 23 feet.

Write a function that has the following characteristics:
-Exponential decay
-Asymptote is y = -2
-Shifted left 3 units from the parent function
9514 1404 393
Answer:
y = 0.4^(x+3) -2
Step-by-step explanation:
I have chosen the decay function y=0.4^x as the parent function.
Shifting any function f(x) left 3 and down 2 will transform it to ...
y = f(x+3) -2
So, the shifted parent function is ...
y = 0.4^(x+3) -2
