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.

A 15 meter long cylinder with a diameter of 7 meters has a square prism
with a base length of 4 meters hole going all the way through the center of
it as shown in the diagram (not to scale). Find the volume of the composite
shape rounding to the nearest cubic meter.
Answer:
The volume of the composite figure is approximately 337.27 m³
Step-by-step explanation:
The given parameters are;
The length of the cylinder, L = 15 meters
The diameter of the cylinder, D = 7 meters
The base length of the square prism, B = 4 meters
We note that the square diagonal of the square = √(4² + 4²) = 4·√2 ≈ 5.66 meters, fits in the cylinder
Therefore, we have;
The volume of the composite figure = The volume of the cylinder - The volume of the square prism
The volume of the cylinder = π/4 × D² × L = π/4 × 7² × 15 ≈ 577.27 m³
The volume of the square prism = B² × L = 4² × 15 = 240 m³
∴ The volume of the composite figure ≈ 577.27 m³ - 240 m³ ≈ 337.27 m³
The volume of the composite figure ≈ 337.27 m³.

((I'LL GIVE BRAINIEST))Write an expression for the perimeter of the triangle shown below: (4 points)
A triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.
a
6.9x − 16
b
6.9x + 16
c
0.1x − 16
d
0.1x + 16
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Perimeter = Sum of the sides
Thus ;
[tex]Perimeter = (0.5x + 9) + ( 3x) + ( - 3.4x - 25) \\ [/tex]
[tex]Perimeter = - 3.4x + 3x + 0.5x - 25 + 9 \\ [/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Answer:
perimeter = A + B + C
perimeter = 0.5x + 9 + 3x + (-3.4x - 25)
perimeter = 0.5x + 3x -3.4x + 9 - 25
perimeter = 3.5x - 3.4x + 9 - 25

Which three (3) characteristics are found in ALL proportional equations.
Answer: A, C and E
Step-by-step explanation:
All proportional equations or lines always go through the origin because when it's x coordinate is 0, it's y coordinate has to be 0 too.
It is also a straight line .
And k will always be the constant value, as if y = kx. K is the constant change or the slope.

A point has the coordinates (0, k).
Which reflection of the point will produce an image at the same coordinates, (0, k)?
a reflection of the point across the x-axis
a reflection of the point across the y-axis
a reflection of the point across the line y = x
a reflection of the point across the line y = –x
Using reflection concepts, it is found that the correct option is:

what is the parallel slope of 9x - 5y = 4
Answer:
-9x+5y=-4
Step-by-step explanation:
Answer:
m= 9/5
Step-by-step explanation:
Parallel lines have the same slope.
So if you can find the slope of the given line, you have the slope you want.
Change the line into the form
y=mx + c
The value of m
will be the slope of the line.
9x −4 = 5y ← to make the y term positive
y=9/5x − 4/5
m=9/5

Help find the measure of G please.
Answer:
G = (x+10) = 42 degrees
Step-by-step explanation:
G is equal to the angle across from it because of the lines being equal.
Then you plug in an equation to solve for all 180 degrees of a triangle 3x + x+10 + x+10 = 180
5x+20 = 180
5x=160
x=32
(32)+10 = 42
G = 42 degrees

Trey deposits $8000 into an account that pays simple interest at a rate of 5% per year. How much interest will he be paid in the first 4 years
6
Answer:
1600
Step-by-step explanation:
You want to calculate the interest on $8000 at 5% interest per year after 4 year(s).
The formula we'll use for this is the simple interest formula, or:
Where:
P is the principal amount, $8000.00.
r is the interest rate, 5% per year, or in decimal form, 5/100=0.05.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 8000 × 0.05 × 4 to get that:
The interest is: $1600.00
Usually now, the interest is added onto the principal to figure some new amount after 4 year(s),
or 8000.00 + 1600.00 = 9600.00. For example:
If you borrowed the $8000.00, you would now owe $9600.00
If you loaned someone $8000.00, you would now be due $9600.00
If owned something, like a $8000.00 bond, it would be worth $9600.00 now.
