Answer:
y = -6 + xt
where t is the rate of rising of the heated mixture per minute
Step-by-step explanation:
From the question, we are lacking an important input. This is the value of the steady rise in temperature. In other terms, this is the rate at which the temperature of the mixture rises per minute.
Let this constant rate be t ° C. What this means is that it rises by this temperature in a minute.
in 1 minute, the temperature rise is t, in two minutes it will be 2t.
Then in x minutes, it will be xt
So adding the initial temperature of minus 6, the equation will be;
y = -6 + xt
The school orchestra sells snacks at thier concerts to raise money. At the spring concert they made 9/8 as much money as they made at their fall concert. Did they make more money at their spring or fall concert?
Answer:
More money was made at the spring concert
Step-by-step explanation:
Here, we want to know if more or less money was made during the spring or fall concert
from the question, we are told that the amount made at spring concert is 9/8 of what is made at a fall concert
Since 9/8 is greater than 1, we can confidently say that the amount made at the spring concert is greater than what she made at the fall concert
The ratio of the numbers of gold to silver to bronze is 2:3:2. What is definitely true about the medals Italy got
(A) Italy got a total of 7 medals
(B) 2/7 of the medals are bronze
(C) 40% of the total medals are gold
(D) more than half of the medals are silver
Answer:
pls help me as well
Step-by-step explanation:
btw which school do u study in?
the only statement that is definitely true based on the given ratio is (B) 2/7 of the medals are bronze.
Based on the given ratio of gold to silver to bronze medals being 2:3:2, we can deduce the following:
(A) Italy got a total of 7 medals: This statement cannot be determined based solely on the given ratio. The total number of medals received by Italy is not explicitly provided.
(B) 2/7 of the medals are bronze: This statement is true. Since the ratio of bronze medals to the total medals is 2/(2+3+2) = 2/7, it means that 2/7 of the medals are bronze.
(C) 40% of the total medals are gold: This statement is false. The ratio given does not indicate that 40% of the medals are gold. Without knowing the total number of medals, we cannot determine the percentage.
(D) More than half of the medals are silver: This statement is false. The given ratio indicates that the number of silver medals is less than the combined number of gold and bronze medals, which means that less than half of the medals are silver.
In summary, the only statement that is definitely true based on the given ratio is (B) 2/7 of the medals are bronze.

An empty shipping box weighs 300 grams the box is then filled with t shirts each t shirt weighs 100 grams the equation 100t + 300 = w represents the relationship between the quantities in this situation where is the weight im grams of the filled box and number if shirts in the box. Select all possible solutions for (t,w) to the equation 100t + 300 =w
Answer:
Step-by-step explanation:
Given the equation of the weight of an empty shipping box expressed as:
100t + 300 = w
We are to select all possible solutions for (t,w) to the equation 100t + 300 =w. From the equation the input variable is t which serves as the DOMAIN while the output variable is w which serves as the RANGE. To get the possible of t, we will need to find the values of t that will make the function to exist. Since the number of t shirts are always positive, this means that the value of t exists on all positive real numbers. Hence the Domain is expressed as:
Domain: [0, ∞)
Since the weight w must also be positive, the lowest value of w we can get it at when t = 0. Substitute into the equation:
100t + 300 =w
100(0) + 300 = w
300 = w
w = 300
Hence the minimum output (weight) that we can have is 300, the Range of the expression will be expressed as:
Range: [300, ∞)
Please ASAP , Help find the original slope and the parallel slope
Answer:
The slope for both is ½ because every unit to the right (x axis) is increasing by 1.
Rise is 1, run is 2
Answer:
slope = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 8, 1) and (x₂, y₂ ) = (8, 9) ← 2 points on the green line
m = [tex]\frac{9-1}{8+8}[/tex] = [tex]\frac{8}{16}[/tex] = [tex]\frac{1}{2}[/tex]

An airline states that an airplane flight between two cities takes 2.5 hours. The airline also says that the actual flying time can change by up to 15% of that amount.
What are the shortest and longest times for the airplane flight? Round your answer to the nearest tenth of an hour.
Enter the correct answers in the boxes.
Answer:
The shortest time is 2.1 hours and the longest time is 2.9 hours
Step-by-step explanation:
First, find the amount of time if it increases by 15%:
2.5(1.15)
= 2.875
= 2.9
Next, find the amount of time if it decreases by 15%:
2.5(0.85)
= 2.125
= 2.1
So, the shortest time is 2.1 hours and the longest time is 2.9 hours
The shortest time for the airplane flight will be; 2.125 hours and the longest time will be; 2.9 hours.
What is the percentage?A percentage is a minimum number or ratio that is measured by a fraction of 100.
Given that the flight take the time is 2.5 hours But the time can fluctuate by 15 %
We need to first calculate 15 % of 2.5 hours.
For this, we will use percentage;
15 % of 2.5 hours
= 15 / 100 × 2.5 hours
= 0.15 × 2.5 hours
= 0.375 hours.
Now, the shortest time is;
= 2.5 h - 0.375 h
= 2.125 h
Then, the longest time will be;
= 2.5 h + 0.375 h
= 2.875 h
Therefore, the shortest time for the airplane flight will be; 2.125 hours and the longest time will be; 2.9 hours.

One angle of a triangle measured 95
the other two angles are in a ratio of 5:12what are the measures of those two angles
Answer:
Both angles: one = 25 degrees, the other equals 60 degrees
Step-by-step explanation:
Do 95 + 5x + 12x = 180.
x = the angle.
95 + 17x = 180.
minus 95
17x = 85
divide by 17.
x= 5
then do 5(5) and 5(12) to get your two angles.
Answer:
25 and 60
Step-by-step explanation:
One angle of a triangle measured 95
the other two angles are in a ratio of 5:12, what are the measures of those two angles?
So 95 + 5x + 12x = 180
(Combine like terms)
95 + 17x = 180
(Subtract 95 from both sides)
17x = 85
(Divide 17 from both sides)
x = 5
Now plug 5 into 5 and 12
5x = 25
12x = 60
60 + 25 + 95 = 180 :)

A rectangle whose area is 336 square feet has a length that is 4 meters less than
the twice the width. Find the dimensions of the rectangle.
Answer:
L = 2(16.675) - 13.2 = 20.15 ft
W = 16.675 ft
Solution
width = x
length = 2x - 4m
m = 3.3 ft
Area = W × L = 336 ft^2
(2x - 4(3.3)) × x = 336 ft^2
solve for x
2x^2 - 13.2x = 336 ft^2
