Joanna is reading a storybook. The ratio of the number of pages she read to
the pages that remain to be read is 7:3. If the book contains 500 pages in all,
how many pages did Joanna read and how many pages remain to be read?
Answers
Answer:
The amount of pages that remain to be read is 150 pages
Step-by-step explanation:
Okay if we know it's in 7:3 ratio we can easily add them both to get 10, then divide 10 by 500 to get 50. SO we now know that 50 is 1 unit and since the ratio says 3 units is the answer, we multiply 50 by 3 to get 150.
A flight with 104 passengers takes off at 1:15. The plane travels 560 miles in 1 hour. At that speed, how far will the plane travel in 3 hours? What information is needed to answer the question?
Answers
Answer:
To find how far the plane will travel, we need the time and length it traveled previously to form the MPH (miles per hour)
Using this information we can make an equation
560/1 = 560 miles in 1 Hour
x/3 = X miles in 3 Hours
560/1 = X/3
X= 1680

Step-by-step explanation:
An airplane is flying overhead at a constant elevation of 405 ft. A person is viewing the plane from a position 3040 ft from the base of a radio tower. The airplane is flying horizontally away from the person. If the plane is flying at the rate of 640 ft/s, at what rate is the distance between the person and the plane increasing when the plane passes over the radio tower? At the moment the plane passes over the tower, the distance between the person and plane is changing at a rate of ________ft/s
Answers
Answer:
δL/δt = 634,38 ft/s
Step-by-step explanation:
A right triangle is shaped by ( y = distance between aircraft and ground which is constant and equal to 405 f ) a person who is at ground level 3040 f away from the tower distance x = 3040 f and the line between the aircraft and the person. Then we can use Pythagoras theorem and write
L ( distance between aircraft and person )
L² = x² + y² or L² = x² + (405)²
Taken partial derivatives with respect to t we get:
2*L*δL/δt = 2*x*δx/t + 0
Then L*δL/δt = x*δx/dt
At the moment of the aircraft passing over the tower
x = 3040 ft δx/δt = 640 ft/s and L = √ ( 3040)² + (405)²
So L = √9241600 + 164025 L = √9405625 L ≈3066,9 ft
Then:
δL/δt = 3040*640/ 3066,9 units [ ft * ft/s / ft ] ft/s
δL/δt = 634,38 ft/s
The sum of two numbers is 23. Twice one number increased by 6 is the same as 4 times the other number decreased by 2. What is the largest of the two numbers?
Answers
Answer:
One number is 4.2, the other is 18.8
Step-by-step explanation:
1.) x+y=23
(x+6y)x2=4
2.) (x+6y)x2=4 = 2x+12y=4
3.)Use elimination/substitution to solve
2x+12y=4 = x+6y=2 = x=2-6y
2-6y+y=23
4.)Solve for y
2-5y=23 -> -5y=21 -> y=4.2.
5.)Solve for x
x+4.2=23
x=18.8

Can someone please help? f(x) = |x − 2| − 4 and g(x) = 1/2x − 2 solve algebraically for x.
Answers
Answer:
x = 8, x = 0 intercepts: (8,2) (0,-2)
Step-by-step explanation:
|x − 2| is a positive value, x can be x ≥ 2 or x ≤ 2
when x≥2, then
y = x-2-4 =x-6 and y = 1/2x - 2
x-6 = 1/2x-2
1/2x=4
x = 8
When x≤2
y = -(x-2)-4 = -x - 2
y = 1/2x - 2
-x - 2 = 1/2x - 2
x = 0

A mass weighing 9 lb stretches a spring 1.5 in. The mass is displaced 5 inch in the downward direction from its equilibrium position and released with no initial velocity. Assuming that there is no damping, and that the mass is acted on by an external force of 5 cos(6t) lb, solve the initial value problem describing the motion of the mass. For this problem, please remember to use English units: ft, lb, sec.
Answers
Answer:
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]
Step-by-step explanation:
Given
[tex]w =9lb[/tex] --- weight
[tex]L = 1.5in[/tex] --- stretch
[tex]u(0) =5in[/tex] --- initial position
[tex]u'(0) =0[/tex] --- initial velocity
[tex]\gamma =0\ lbs/ft[/tex] --- no damping
[tex]F(t) = 5cos(6t)\ lb[/tex] -- External force
Required
Solve the initial value problem
The initial value problem is calculated using:
[tex]mu" + ku = F(t)[/tex]
First, convert all lengths to ft
[tex]L = 1.5in[/tex]
[tex]L = \frac{1.5}{12}ft[/tex]
[tex]L = \frac{1}{8}ft[/tex]
[tex]u(0) =5in[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex]
Weight is calculated as:
[tex]w = mg[/tex] and [tex]w = kL[/tex]
Where
[tex]g = 32fts^{-1}[/tex]
Make m the subject in [tex]w = mg[/tex]
[tex]m = \frac{w}{g}[/tex]
[tex]m = \frac{9}{32}[/tex]
Make k the subject in [tex]w = kL[/tex]
[tex]k = \frac{w}{L}[/tex]
[tex]k = \frac{9}{1/8}[/tex]
[tex]k = 72[/tex]
Recall that: [tex]mu" + ku = F(t)[/tex]
[tex]\frac{9}{32}u" + 72u = 5cos(6t)[/tex]
Multiply through by 32
[tex]9u" + 2304u = 160cos(6t)[/tex]
[tex]u(0) = \frac{5}{12}ft[/tex] and [tex]u'(0) =0[/tex]
