The area of a rectangular room is 238 square feet. The width is 3 feet less than the length. Find the dimensions of the room.
Answers
Answer:
Step-by-step explanation:
L= length
w= width= L-3
A= area= 238 ft^2
LENGTH
Area Formula
A= LW
substitute w value
238= (L)(L- 3)
multiply L by parentheses
238= L^2 - 3L
subtract 238 from both sides
0= L^2 - 3L - 238
factor
0= (L + 14)(L - 17)
set each parentheses equal to 0
0= L + 14
-14= L
OR
0= L - 17
17 ft= L
*Since the measure of a rectangle would not be negative, L= 17 ft
WIDTH
w= L - 3
w= 17 - 3
w= 14 ft
ANSWER: Length= 17 ft; Width= 14 ft
Answer:
Length= 17 ft; Width= 14 ft
Step-by-step explanation:
L= length
w= width= L-3
A= area= 238 ft^2
LENGTH
Area Formula
A= LW
substitute w value
238= (L)(L- 3)
multiply L by parentheses

kelsey goes cliff diving into the ocean. Her height as a function of time can be modeled by the function h(t)=-16t^2+480, where t is the time in seconds and h is the height in feet. How long does it take for Kelsey to reach the water?
Answers
Answer:
to differential calculus, because I don't know how to answer this question without
using it.
We're told that Jason's height above the water is H(t) = -16t² + 16t + 480 .
We can observe many things from this equation:
-- Up is the positive direction; down is the negative direction.
-- The acceleration of gravity is 32 ft/sec² .
-- Jason jumps upward from the cliff, at 16 ft/sec .
-- The cliff is 480-ft above the water.
(This tells us why the question is only concerned with his maximum height,
and then it ends ... 480-ft is one serious cliff, and what happens after the
peak of his arc is too gruesome to contemplate.)
In any case, his vertical velocity is the first derivative, with respect to time,
of his height above the water.
V = -32 t + 16
At the peak of his arc, where gravity takes over, his velocity changes from
upward to downward, and it's momentarily zero.
0 = -32t + 16
Add 32t to each side: 32t = 16
Divide each side by 32: t = 1/2 second
His height at that instant is H(0.5) = -16(0.5)² + 16(0.5) + 480 =
4-ft above the cliff, 484-ft above the water,
and then he begins falling from that altitude.
The duration of his dive is 484 = 16 t²
t = √(484/16) = 5.5 seconds
and he hits the water at V = a t = (32) x (5.5) = 176 ft/sec = exactly 120 mph

A school ordered $600 worth of light bulbs. Some of the light bulbs cost $1 each and the others cost $2 each. If twice as many $1 bulbs as $2 bulbs were ordered, how many light bulbs of each type were ordered?
Answers
Answer:
A school ordered 300 bulbs that cost $1 and 150 bulbs that cost $2.
Step-by-step explanation:
Let [tex]u[/tex] denotes number of light bulbs that cost $1 and [tex]v[/tex] denotes number of light bulbs that cost $2.
Twice as many $1 bulbs as $2 bulbs were ordered.
[tex]u=2v[/tex]
A school ordered $600 worth of light bulbs.
[tex]u(1)+v(2)=600\\u+2v=600[/tex]
Put [tex]u=2v[/tex] in [tex]u+2v=600[/tex]
[tex]2v+2v=600\\4v=600\\\\v=\frac{600}{4}\\\\v=150[/tex]
Put [tex]v=150[/tex] in [tex]u=2v[/tex]
[tex]u=2(150)=300[/tex]
Therefore,
A school ordered 300 bulbs that cost $1 and 150 bulbs that cost $2.

honestly i was a little confused with the way this question was worded so please tell me if i did something wrong or if i didn't explain/understand this right!
answer:
3 dollars or 300 cents
step-by-step explanation:
well we know that 4 quarters equal one whole dollar so what i did was divide 12 by 4 to get 3 whole dollars
12/4
= 3 dollars
and we know that 100 pennies equal one whole dollars, all you need to do was multiply 3 dollars by 100 pennies
3 * 100
= 300 pennies
showing you that abby has 300 cents in her piggy bank

The triangle above is a right triangle with side lengths a = 7 in, b = 24 in, and c= 25 in.
Which statement is true?
Answers
The sum of the squares of the two smaller sides is equal to the square of the third side.
What is a triangle?A triangle is a 3-sided shape that is occasionally referred to as a triangle. There are three sides and three angles in every triangle, some of which may be the same.
The sum of all three angles inside a triangle will be 180° and the area of a triangle is given as (1/2) × base × height.
There are many types of triangles such that right angle triangle, equilateral triangle, and much more.
Given,
Δabc is a right-angle triangle
By Pythagoras theorem
Hyp² = perp² + base²
Here
Hyp = c (longer side)
Pepe and base = a and b
So,
c² = a² + b²
(Longer side)² = a² + b²
Hence, The sum of the squares of the two smaller sides is equal to the square of the third side.

The sum of the squares of the two smaller sides is equal to the squares of the third side.
Option B is the correct answer.
Given,
The triangle above is a right triangle with side lengths a = 7 in, b = 24 in, and c = 25 in.
We need to see which option is true.
What is the Pythagorean theorem?It states that in a right-angled triangle the square of the hypotenuse is equal to the sum of the squares of the other two sides.
We have,
The triangle above is a right triangle with side lengths:
a = 7 in
b = 24 in
c = 25 in
Here c = hypotenuse.
So applying the Pythagorean theorem.
c^2 = a^2 + b^2
25^2 = 7^2 + 24^2
625 = 49 + 576
625 = 625
We see that the given values satisfy the Pythagorean theorem.
Thus the sum of the squares of the two smaller sides is equal to the squares of the third side.
Option B is the correct answer.
