What do you mean by simplest form?
A fraction with a denominator and numerator that are both relatively prime has the simplest form. It indicates that the fraction's numerator, which is the portion at the top of the fraction, and denominator, which is the portion at the bottom, do not share any factors other than one.
An amount that represents a fraction of a whole is called a fraction. A fraction's reduced form is another name for its simplest form. A fraction with a common factor of one, such as 34, has the simplest form. Although 2/4 can be further simplified and written as 12, it is not the most basic form. The fractions 12 and 2/4 are equivalent in this case, we can also say.

Blake wants to build a rectangular enclosure for his animals. One side of the pen will be against the barn, so he needs no fence on that side. The other three sides will be enclosed with wire fencing. If Blake has 950 feet of fencing, you can find the dimensions that maximize the area of the enclosure.
a) Let w be the width of the enclosure (perpendicular to the barn) and let l be the length of the enclosure (parallel to the barn). Write a function for the area A of the enclosure in terms of w . (HINT: First write one equation with w and l and one equation with w and l and A. Solve for l in the first equation and substitute for l in the other). A ( w ) = ____________
b) What width w would maximize the area? w = __________________ ft
c) What is the maximum area? A = ______________ square feet
Answer:
(a) A(w) = w(950-2w) = 950w-2w^2
(b) w = 237.5
(c) A = 112812.5
Step-by-step explanation:
First of all the maximum area is always a square. You can get the answer first to check your work later.
950/4 = 237.5
One side is not needed so add that length to the non-parallel side.
237.5+237.5=475 feet is the length and 237.5 feet is the width(s)
A=475*237.5
A=112812.5 square feet
Doing the algebra...
P=l+2w
950=l+2w
950-2w=l
A=lw
A=(950-2w)w
A=950w-2w^2

The volume of a particular die is 7200 mm³. Use the fact that 10 mm equals 1 cm to convert this volume to cm³. Round your answer to the nearest tenth.
Answer: 720.0 cm³
Step-by-step explanation:
To convert the volume of the die from millimeters to centimeters, we need to divide the volume by the conversion factor that relates millimeters to centimeters. Since 10 millimeters is equal to 1 centimeter, the conversion factor is 10.
To convert the volume to centimeters, we can divide it by the conversion factor:
7200 mm³ / 10 = 720 cm³
This means that the volume of the die is 720 cm³. Rounded to the nearest tenth, the volume of the die is 720.0 cm³.

The U-Drive Rent-A-Truck company plans to spend $16 million on 320 new vehicles. Each commercial van will cost $25,000 each small truck $80,000, and each large truck $70,000. Past experience shows that they need twice as many vans as small trucks. How many of each type of vehicle can they buy?
If each large truck $70,000. Past experience shows that they need twice as many vans as small trucks. The number of each type of vehicle they can buy is; Small truck 80, Commercial van 160, Large van 80.
How to find the number of vehicle?Since the company intends to purchase 320 vehicle, Let write this equation:
C + S + L = 320 (Eq. 1)
Total cost of the vehicles:
25C + 80S +70L = 16,000 (Eq. 2) (Divided by 1000 to keep the numbers small)
Number of commercial vans is twice the number of small trucks,
C = 2S
Substituting 2S in place of C in Eq. 1 and Eq. 2
2S + S + L = 320
25(2S) +80S +70L = 16,000
130S + 70L = 16,000
Multiplying the first of those equations by 70
210S + 70L = 22,400
130S + 70L = 16,000
Subtracting the second equation from the first:
80S = 6400
Divide both side by 80S
S = 6400/80
S = 80 (Small truck)
Then:
C = 2S
C= 2(80)
C= 160 (Commercial van)
So,
C + S + L = 320
160 + 80 + L = 320
L = 320 - 160 - 80
L =80 (Large van)
Therefore the number of each type of vehicle they can buy is; Small truck 80, Commercial van 160, Large van 80.

$14.94
$11.25
$10.76
$15.00
Answer:
$11.25
Step-by-step explanation:
If Stephen receives a 4.5% hourly pay increase each year, his hourly pay will be $10.30 + (4.5% * $10.30) = $10.30 + $0.465 = $10.765 after the first year.
In the second year, his hourly pay will be $10.765 + (4.5% * $10.765) = $10.765 + $0.486 = $11.251.
Therefore, in two years, Stephen's hourly pay will be $11.251. This is closest to the answer choice of $11.25, so it is the correct answer.

The result of adding -1 to the inequality's two sides is
|4x + 8| - 1 ≥ - 1
But since |4x + 8| - 1 is identical to f(x) = y, we have y = f(x) - 1, which means that the range is specified for all values larger than -1.
So the range is -1 ≤ y < ∞
Thus,the vertex and range of y = |4x + 8| - 1 will be (-2, -1) ; -1 ≤ y < ∞ respectively.

Biologists stocked a lake with 800 fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be 6600 . The number of fish grew to 1020 in the first year.
a) Find a logistical model for the number of fish P(t) after t years
P(t)=
b) How long will it take for the population to increase to 3300 hhalf of the carrying capacity)?
It will take years.
Answer:
Below
Step-by-step explanation:
from 800 to 1020 is a 220/800 * 100% = 27.5% increase each year
P(t) = 800 ( 1 + .275)^t
3300 = 800 ( 1+.275)^t
3300 / 800 = 1.275 ^t LOG both sides
.615423 / LOG 1.275 = t = 5.83 years
