The inequality equation for the measurements of the rectangular field must satisfy t<225.
If two real numbers or algebraic expressions are related by the symbols “>”, “<”, “≥”, “≤”, then the relation is called an inequality.
Given that,
The length of the rectangle is 2t meters
the breadth of the rectangle is 50 meters
The perimeter of the rectangle is given by 2×(length+breadth)
Here the perimeter of the rectangle is less than 1km=1000meter
Forming an equation with the given data
2×(2t+50)<1000
2t+50< 1000/2
2t+50<500
2t<500-50
2t<450
t<450/2
t<225
Thus, The inequality equation for the measurements of the rectangular field must satisfy t<225.

Steven has a rope that is 6 ft long. He cuts it into 9 pieces, as shown in the model.
The model shows that there are 9 pieces that are each 2/3 ft long.
Which division equation represents the situation?
Answer: 6 divided by 2/3 = 9
Step-by-step explanation:
For division always take the first number in the word problem so in this question the answer would be 6 then you take the 2/3 and divide it by 6. So it would be 6 divided by 2/3. then you take the 9 from the word problem and do 6 divided by 2/3 equals 9. So in this question the answer would be option 2 or could also be called option B. And if this is it that means the answer is, 6 divided by 2/3 = 9.
The division equation which representant this situation is 6 ÷ 2/3 = 9.
What is an division equation?Division equations are mathematical equations with the division operator in them. Division equations are useful not only in math class, but in everyday life as well. For example, if we wanted to evenly distribute a bag of candies among our friends, we could use division to find our answer. Assume we have 100 candy bars and four friends. Divide 100 by 4 to find out how many candies each person gets. We discover that our answer is 25, which means that each of our friends receives 25 candies.
It's our job to figure out what the division equals. This can be represented by a variable, such as x. As a result, our total division equation will be: 100/4=x. On both sides of the equals sign, we have things.

Answer:
The required linear function for the temperature T, in degrees Fahrenheit, of the oven m minutes from the time it was turned on until it reaches the desired temperature is T = 54m + 80.
Step-by-step explanation:
Given that,
An oven is turned on and set to reach the desired temperature of 350 degrees Fahrenheit. The oven warms up at a constant rate. The oven’s temperature is 134 degrees Fahrenheit at 1 minute and it reaches its desired temperature at 5 minutes.
What are functions?
Functions is the relationship between sets of values. e g y=f(x), for every value of x there is its exists in set of y. x is the independent variable while Y is the dependent variable.
Here,
At time m = 1 min, temperature T = 134 °F
At time m = 5 min. temperature T = 450 °F
Slope of the equation M = 450 - 134 / 5 - 1
= 216 / 4
= 54
Linat relationship can be given as,
T - 134 = 54 (m - 1)
T = 54m -54 + 134
T = 54m + 80
Thus, the required linear function for the temperature T, in degrees Fahrenheit, of the oven m minutes from the time it was turned on until it reaches the desired temperature is T = 54m + 80.

How do you solve complex fractions with rational expressions?.
To solve a complex fraction, which is a fraction that contains one or more fractions in its numerator and/or denominator, you can follow these steps:
Factor the numerator and denominator of the complex fraction if possible. This will make it easier to cancel common factors.
Multiply both the numerator and denominator by the reciprocal of the fraction(s) in the denominator. This will eliminate the fraction(s) in the denominator, leaving a simplified expression.
Simplify the resulting expression by combining like terms, if possible.
Check your work by multiplying the numerator and denominator of the original complex fraction by the reciprocal of the fraction(s) in the denominator, and verifying that the simplified expression you obtained is equivalent.

Answer:
B
Step-by-step explanation:
1. Before anything, figure out the inequality symbol. Why? In the solutions, all of the inequalities are different so you narrow it down by figuring out the inequality sign.
2. "At most 50 pounds" means we can't go over 50 pounds, but the package can still equal 50, that's just the most it can be. This means we will have a line underneath because it includes the maximum number, 50, in the solution.
3. "At most" also means the package (x) cannot be over 50. The sign opening must face 50 because that shows x has to be less than. But it can equal 50, so the sign is [tex]x\leq 50[/tex]. That would be B.
4. About the numbers, the box weighs 2 pounds. This means it is x+2 because weight is not negative and it is ADDING weight to what we don't know. To isolate x, just do 50-2, and you get 48. That again proves b is the answer.

For given functions for zombies and vampires, zombies will reach 50,000 first.
What is a function?
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).
There are several types of functions in math. Some important types are:
Injective function or One to one function: When there is mapping for a range for each domain between two sets.
Surjective functions or Onto function: When there is more than one element mapped from domain to range.
Polynomial function: The function which consists of polynomials.
Inverse Functions: The function which can invert another function.
Now,
Initial numbers, 100 Zombies and 100 Vampires.
In function z(t), the zombies increase in population by 1000 per day,
and in function V(t), the vampire population increases by 25% each day,
Therefore, z(t)=100+1000t where t=no, of days and
v(t)=100+25t where t= no. of days
for z(t)=50000
100+1000t=50000
t=49900/1000=49.9≈50days
for v(t)=50000
100+25t=50000
t=49900/25=1996 days

How to solve for the amount left in the containerTo find the amount left in the container the amount used to feed the fish in each case will factored and then used for subsequent feeding. of the fish.
From the problem it can be deduced that the initial amount in the container was 2 tsp
The routine feeding of the fish include:
Alice fed her fish 1/4 tsp, of food before school = 1/4 * 2 = 1/2
The 2 tsp has reduced to 1/2, this is further used as shown below
Alice fed her fish 3/4 tsp, of food after school = 3/4 * 1/2 = 3/8 tsp

For any equation of the type y=ax²+bx+c, the vertex is given by (h, k)
Where, h = -b/2a and k = (4ac - b²)/4a.
Given, the equation is y = 3x²+ 6x+3

Triangle ABC is a right triangle with the right angle at angle B. If the sine of angle A is ? and the longer leg is 52 inches, what is the length of the shorter leg of the triangle?
Answer:
The length of the shorter leg of the triangle can be calculated using the Pythagorean Theorem. The formula is a^2 + b^2 = c^2, where a is the length of the shorter leg, b is the length of the longer leg and c is the length of the hypotenuse. In this case, a^2 + 52^2 = c^2. The hypotenuse can be calculated by using the sine formula. c = (52/sinA). Substituting this value into the Pythagorean Theorem equation, a^2 + 52^2 = (52/sinA)^2. Solving for a, a = sqrt(52^2 - (52/sinA)^2).

a) The numeric value at x = 4 is given as follows: f(4) = 64.
b) The logarithmic expression is given as follows: x = log2(16).
How to find the numeric value of a function or of an expression?To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.
The function for this problem is defined as follows:
f(x) = 4(2)^x.
At x = 4, the numeric value is found replacing the lone instance of x by 4, hence:
f(4) = 4(2)^4 = 64.
For the logarithmic expression, we obtain the inverse function, hence:
64 = 4(2)^x.
2^x = 16
x = log2(16).

Solution:
Initial Coordinates=(5,0)=(xi,yi)→xi=5, yi=0
Final Coordinates=(10,0)=(xf,yf)→xf=10, yf=0
Scale factor=xf/xi=yf/yi
We divide the final coordinates by the initial coordinates. In this case the ordinates (yf and yi) are zero and we can't divide by zero, but the abscissas (xf and xi) are different of zero, then we can use them:

2x + 3y = 8
3x + 2y = 7
Start by solving for x in the first equation by subtracting 3y from both sides:
2x + 3y = 8
2x = 8 - 3y
x = (8 - 3y)/2
Now substitute this expression for x in the second equation:
3(8 - 3y)/2 + 2y = 7
24 - 9y + 2y = 7
11y = 17
y = 17/11
Finally, solve for x, add y = 17/11 to the first equation as follows:
2x + 3(17/11) = 8
2x + 51/11 = 8
2x = 8 - 51/11
x = (8 - 51/11)/2
x = 21/22
The solution is x=21/22 and y=17/11.
