Answer:
20
Step-by-step explanation:
Make 5 a fraction which would be 5/1
Then make an expression, "5/1 / 1/4"
Then switch and flip meaning make the division sign a multiplication sign and make 1/4 into 4/1.
Your expression should look like 5/1 x 4/1
Then multiply 5 and 4 and you get 20. You do not need to write it as a fraction.

Which inequality describes the graph
Y < 3/4x -3
Y _> 3/4x -3
Y _< 3/4x -3
Y > 3/4x -3
Answer: Choice B) [tex]y \ge \frac{3}{4}x-3[/tex]
The boundary is the equation y = (3/4)x-3 which goes through (0,-3) and (4,0)
This boundary is a solid line. Since it's a solid line, we will involve "or equal to" as part of the inequality sign.
The shading above the boundary line indicates we'll also have "greater than" as part of the inequality sign.
So overall, the inequality sign is "greater than or equal to". That leads to choice B.

The diameter of a cylinder is 5 yd. The height is 4 yd. What is the volume of the cylinder
Answer:
25 pi square yd OR rounded pi to 3.14: 78.5 square yd
Step-by-step explanation:
Use the formula volume of cylinder = base area × h to determine the value of the base area.
Diameter: 5 yd
Height: 4 yd
(5/2)^2 Pi x 4 = 25 pi square yd.
Answer:
78.5 yd
Step-by-step explanation:
= [tex]\pi[/tex]r²h
= (3.14)(2.5)²(4)
= (3.14)(6.25)(4)
= 19.625 x 4
= 78.5 yd

Constant terms are terms with no variables attached to them, and will not change under any circumstances. A variable is typically denoted by a Latin Alphabet.
4. 4
The coefficient is the whole number found in front of the variable, typically being multiplied to it. In this case, you are solving for the coefficient that is found in front of g², which is 4.
5. -3c
The coefficient -3 is found at the 3rd term of the expression.
6. -12x & -17x ; 15y & 16y
Like terms are terms with the same variable as well as the same amount of variables. For example x² is not a like term of x, though both variables have x to signify them.
7. 3c
Unlike terms are terms that do not share at least one partner of the same amount of variables. c is a variable by itself with no other terms containing it, and so is your answer.

Write the equation of the line that passes through the points (4,-1) and (4,8). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answer:
x = 4
Step-by-step explanation:
Given the points (4, - 1) and (4, 8)
Note the x- coordinates are 4 in both cases.
This indicates the line passing through the points is vertical with equation
x = c
where c is the value of the x- coordinates the line passes through. In this case 4, thus
x = 4 ← equation of vertical line
Let P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours. The rate at which the drug leaves the bloodstream is proportional to the amount of the drug in the bloodstream. The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours. At time t = 0,500 milligrams of the drug was administered. At the moment when the amount of the drug in the bloodstream is 50 milligrams, the amount is decreasing at a rate of 11.5 milligrams per hour. Which of the following is an expression for P (t)?
A. P(t) = 500 – 0.23t.
B. P(t) = 500 – 0,23 42.
C. P(t) = 500e -0.231.
D. P(t) = e-0.23+ + 499.
As proportional relationship, the amount decreasing at a rate milligrams per hour can be written in expression P(t) = 500 + e⁻⁰²ˣ
What is Proportional relationship?In math, the relationships between two variables where their ratios are equivalent is known as proportional relationship.
Given that P(t) represent the amount of a certain drug, in milligrams, that is in the bloodstream at time t hours.
Here we have the rate at which the drug leaves the bloodstream proportional to the amount of the drug bloodstream.
The amount of the drug in the bloodstream can be modeled by dP/dt = kP, where k is a constant and t is time, in hours.
Here we need to find the expression.
Bloodstream = 500 milligrams
So, the expression for this proportional relationship is written as;
P(t) = 500 + e⁻⁰²ˣ

(07.02 MC) what is the value of y in the equation 3(3y - 15) = 0?
Answer:
[tex]y = 5[/tex]
Step-by-step explanation:
Given equation:
[tex]3(3y - 15) = 0[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3(3y - 15)}{3} = \dfrac{0}{3}[/tex]
[tex]\implies 3y-15 = 0[/tex]
Add 15 to both sides:
[tex]\implies 3y-15 +15= 0+15[/tex]
[tex]\implies 3y=15[/tex]
Divide both sides by 3:
[tex]\implies \dfrac{3y}{3}=\dfrac{15}{3}[/tex]
[tex]\implies y=5[/tex]
Answer:
The value of y is 5.
Step-by-step explanation:
First, we will distribute 3 on (3y - 15) This means 3(3y) - 3(15) = 0. Now, we will multiply 3 by what is inside the parentheses for each value. This gives us 9y - 45 = 0. After that, we will add 45 to both sides, which leaves us with 9y = 45. Finally, we will divide 45 by 9 to give us the y value, 5. I hope this helped (:

A 2-column table with 4 rows. The first column labeled Elevation (meters) has entries 500, 1000, 1500, 2000. The second column labeled Temperature of air (degrees Celsius) has entries 11. 8, 8. 5, 5. 3, 2. 0. As elevation increases, temperature decreases. At which elevation will sound travel fastest? 500 meters 1,000 meters 1,500 meters 2,000 meters.
At an elevation of 500m, the sound will travel fastest.
Elevation Temp
500m 11.8°C
1000m 8.5°C
1500m 5.3°C
2000m 2.0°C
Why do sounds travel at a faster rate at high temeratures?We know that air molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly because the more is the medium, the more quickly sound waves propagate.
So, when the given temperature is maximum i.e. 11.8°C, the sound will travel fastest. The elevation corresponding to 11.8°C is 500m.
So, Sound will travel fastest at 500m elevation.
Therefore, At an elevation of 500m, the sound will travel fastest.

guys i NEED HELP NOW! ansewr this ( 2 1/4) x (-8)
Answer:
-18
Step-by-step explanation:
If you turn 2 1/4 into an improper fraction, you get 9/4
Turn -8 into an improper fraction, you get -8/1
Equation: 9/4*-8/1
You can cross cancel the 4 and the 8 so your equation becomes 9/1*-2/1 which becomes 9*-2
Multiply and you get -18 :)
