Mr green Drove 100 mies in 2 hours he continues to drive the same speed how long will mr green take to drive 400 more miles
Answer:
It would take him 8 hours
Since every 50 miles takes 1 hour
━━━━━━━☆☆━━━━━━━
▹ Answer
8 Hours
▹ Step-by-Step Explanation
First, find the unit rate:
100 miles ÷ 2 hours = 50 mph
Now, we need to find the time it takes to drive 400 miles so we will divide:
400 miles ÷ 50 mph = 8 hours
If you are looking for total hours, you would add:
2 hours + 8 hours = 10 hours
If you are looking for how long it'll take to drive the 400 miles, it would just remain 8.
Hope this helps!

fb + 3b = d solve for b
Answer: the answer is d/f+3
sorry i couldnt find my work for this problem but i hope it helps !
An equation is formed of two equal expressions. When in the given equation the value fo b is d/(f+3).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
fb + 3b = d
Take b as a common term from both the terms on the left side of the equation,
b(f + 3) = d
Divide both the sides of the equation by (f+3),
b(f + 3)/(f+3) = d/(f+3)
Simplify,
b = d/(f+3)
Hence, when in the given equation the value fo b is d/(f+3).

A cylindrical tube has a length of 14.4cm and a radius of 1.5cm and is filled with a colorless gas. If the density of the gas is known to be 0.00123g/cm 3 , what is the mass of the gas in the tube in mg?
Answer:
0.125214 gStep-by-step explanation:
we know that density is given as
density=mass/volume
the volume of the cylinder
v= πr^2h
v=3.142*1.5^2*14.4
v=3.142*2.25*14.4
v=101.8cm^3
Given that density =0.00123g/cm^3
mass= density*volume
masss= 0.00123*101.8
mass= 0.125214 g

Given: 2n=m+h, h=n+m; prove n=2m
An equation is formed of two equal expressions. n=2m can be proved by solving the two of the given equation for h and then equating them together as shown below.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given the two equations, 2n=m+h, and h=n+m. Now, solve the two of the equations for h as shown below.
Equation 1.
2n = m + h
2n - m = h
h = 2n - m
Equation 2.
h = n + m
Further, equate the value of h from both the equation,
h = h
2n - m = n + m
Bring the like terms on the same side of the equation,
2n - n = m + m
n = 2m
Hence, proved n=2m.

The sum of two consecutive numbers is 63. Find the two numbers.
Answer:
the two numbers are 31 and 32.
Step-by-step explanation:
x+(x+1)=63
2x+1=63
2x=62
x=31
The answers are 31 and 32
The sum of two consecutive numbers is 63. Consecutive numbers are numbers that are in a row (e.g. 1, 2, and 3 are consecutive integers). This means we can represent the two consecutive numbers with x and x+1. Plugging the numbers back into the equation, you get
x + x+1 = 63
Simpifying, you get
2x+1 = 63
Now, you just need to isolate x. To do this, you should subtract 1 from both sides, making the equation.
2x=62
Lastly, you need to divide both sides by 2, making making the equation
x=31
The two integers are x and x+1, and when you plug 31 into that, the numbers are 31 and 32.

The frequency vibrations for a certain guitar string When is blood can be determined by the equation below, Where F is the number of vibration per second and T is measured in pounds.If the frequency of the vibrations is 600 vibrations per second, How many pounds of tantrums was used to plug the string? F = 200sqrt(T)
Answer:
9 poundsStep-by-step explanation:
Given the frequency vibrations for a certain guitar string modeled by the equation
F = 200√T where:
T is amount of tantrums in pounds
If the frequency of the vibrations is 600 vibrations per second, the amount of pounds in tantrums will be gotten by substituting F = 600 into the equation and calculating T as shown:
600 = 200√T
Divide both sides by 200
600/200 = 200√T /200
3 = √T
Square both sides
3² = (√T)²
9 = T
T = 9
Hence 9 pounds of tantrum was used to plug the string
the grade 8 has hired a disk jockey the disk jockey takes 85$ plus 2 for each student that attends. The disk jockey was paid 197 how many students attended
Answer:
56 students
Step-by-step explanation:
The equation for your question is 85+2x=197. First you would have to subtract 85, on both sides, leaving you with 2x=112. Then, you'd have to divide by 2 on both sides to isolate the variable. From there, you're left with x=56.
