Isaac conducted a scientific experiment. For a certain time, the temperature of a compound rose 3 3/4 degrees every 3/4 of an hour. What was the rate, in degrees per hour, that the temperature of the compound rose?
Answer: it should be 5
Step-by-step explanation: if 3 3/4 divided into three parts its 1 1/4. If we add 3 3/4 and 1 1/4, then we have 5
The rate of rise in temperature in degrees per hour will be equal to 5° per hour.
What is an arithmetic operation?The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.
Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.
As per the given information in the question,
The temperature rise of the compound to 3 3/4° every 3/4 of an hour.
1 hour = 60 minutes then,
3/4 of an hour = 3/4 × 60 = 45 minutes.
(15/4)° rise in 45 minutes or,
3.75° rise in 45 minutes.
Let the rise in temperature in 1 hour will be x° then,
x = (3.75 × 60)/45
x = 5° per hour.

The value of y is directly proportional to the value of x. Given y = 25 when x = 150.
What is the value of y when x = 60?
Enter your answer in the box.
y=
helppp!!
Answer:
Step-by-step explanation:
Y = kx
25 = k150
25/150 = k
0.166 = k
When the value of x = 60
y = (0.166)(60)
y = 9.96
The value of y for x = 60 will be;
⇒ y = 10
What is Proportional?
Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
The value of y is directly proportional to the value of x.
And, Given y = 25 when x = 150.
Now,
Since, The value of y is directly proportional to the value of x.
Hence, We get;
⇒ y = kx
⇒ 25 = k × 150
⇒ 25/150 = k
⇒ k = 1/6
So, The value of y when x = 60 is,
⇒ y = kx
⇒ y = 1/6 × 60
⇒ y = 10
Thus, The value of y for x = 60 will be;
⇒ y = 10
