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?

Answers

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.

b

c

Answers

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

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]

[tex]Perimeter = 0.1x - 16[/tex]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

Thus the correct answer is (( c )) .

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

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

perimeter = 0.1x + 9 - 25

perimeter = 0.1x - 16

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

Answers

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.

Alex and Freddy collect stamps. The number of stamps in Alex’s collection is in ratio 3:5 to the number of stamps in Freddy’s collection. If Freddy gives Alex 10 stamps, the ratio will change to 7:9. How many stamps are in both collections together?

Answers

suppose Alex has 3x stamps, Freddy has 5x stamps. After Freddy gives Alex 10 stamps, Alex has 3x+10 while Freddy has 5x-10
the new ratio is 7 to 9, so we have the equation: (3x+10)/(5x-10)=7/9
9(3x+10)=7(5x-10)
27x+90=35x-70
160=8x
x=20
So Alex has 3*20=60 stamps while Freddy has 5*20=100. Together they have 160

What is the equation of this graphed line?
Enter your answer in slope-intercept form in the box

Answers

The line intersects the y-axis at -5, so that’s our y-intercept.
The slope can be found by using the slope formula:
m = (y2 - y1) / (x2 - x1)

Our give coordinates are (-6, -3) and (6, -7)
Plug the x and y values into the formula:
m = (-7 + 3) / (6 + 6)
m = 4/12
m = 1/3

Use the equation for slope-intercept form:
y - y1 = m(x - x1)

Plug in the values for each variable:
y + 6 = (1/3)(x + 3)
y + 6 = (1/3)x + 1
y = (1/3)x - 5

The answer is y = (1/3)x - 5
