For the inequality t < -1, the numbers that are solutions to this inequality are -2, -3, and -10, as they are all less than -1.\
The inequality in question is t < -1, which indicates that the temperature (t) is colder than -1 degrees Fahrenheit. On a number line from -2 to +2, the numbers that satisfy this inequality would be all the numbers that are less than -1. Therefore, the solutions to the inequality would be the numbers that are to the left of -1 on the number line.
-2
-3
-10
The numbers 0, 1, and -1 do not satisfy the inequality because they are not less than -1.
which of the following is a polynomial?
A. (x^8 - 2) / (x^-2 + 3)
B. 1/x - 1
C. x^2 + 2
D. 7x^7 -2x^-4 + 3
A polynomial is an expression involving addition, subtraction, multiplication, and non-negative integer exponents of variables. Among the options provided, only option C (x^2 + 2) is a polynomial. The correct answer is C.
To determine which of the given options is a polynomial, we need to understand what a polynomials are. A polynomial is an expression that consists of variables and coefficients, involving only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.
Here are the given options:
(A) (x^8 - 2) / (x^-2 + 3)(B) 1/x - 1(C) x^2 + 2(D) 7x^7 -2x^-4 + 3Let's analyze each option:
Option A: (x^8 - 2) / (x^-2 + 3) - This is not a polynomial because it has a variable in the denominator. Option B: 1/x - 1 - This is not a polynomial because of the variable in the denominator. Option C: x^2 + 2 - This is a polynomial. It consists of terms with non-negative integer exponents. Option D: 7x^7 -2x^-4 + 3 - This is not a polynomial because it includes a term with a negative exponent (-2x^-4).Thus, the correct answer is option C, x^2 + 2.

Write an equation of the circle with center (-3, 4) and radius 6.
Answer:
(x+3)²+(y-4)²=36.
Step-by-step explanation:
For this, we need to use the equation of a circle which is:
(x-h)²+(y-k)²= r²
Simply substitute the center values for 'h,k', and the radius for 'r'.
This will give you:
(x+3)²+(y-4)²=36.

This is a right triangle, and we know this because of the little square in the corner. Therefore, we can use the Pythagorean theorem.
a^2+b^2=c^2
a and b are the legs, and c is the hypotenuse.
We know the 6 and the unknown side are the legs, since they form the right angle. We also know that 10 is the hypotenuse, since it is opposite the right angle.
6^2+b^2=10^2
Evaluate the exponents
36+b^2=100
Now, we need to solve for b. To do this, we need to get by itself. First, subtract 36 from both sides
36-36+b^2=100-36
b^2=64
Take the square root of both sides
[tex]\sqrt{b^2}=\sqrt{64}[/tex]
b=8
So, the the unknown side is 8

The linear equation y=45x describes how far from home Traci is as she drives from San Francisco to Dawson. Let x represent the number of hours and y represent the number of miles. How far from home is Traci in 12 hours? Graph the equation and tell whether it is linear.
An equation is formed of two equal expressions. The distance between Traci and her home after 12 hours is 540 miles.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Given that the linear equation y=45x describes how far from home Traci is as she drives from San Francisco to Dawson. where x represents the number of hours and y represents the number of miles.
Therefore, the distance covered by Traci in 12 hours is,
y = 45x
y = 45(12)
y = 540 miles
Hence, the distance between Traci and her home after 12 hours is 540 miles.

David, Chen, and Leslie raised money for the school in a walk-a-thon. Altogether they made $46. Leslie made $10. Chen made twice as much as David. How much did David make?
Answer:
David made $18
Step-by-step explanation:
Leslie made $10. This means that you take 46-10=36
Chen-Chen made twice as much as David so 36/2=18 So Chen made $9.
David- 36-18= 18 So, David made 18 dollars.
In this mathematics problem, David, Chen, and Leslie together raised $46, with Leslie raising $10. Given that Chen raised twice as much as David, we can represent David's earnings as 'x' and Chen's as '2x'. By solving the resulting equation 3x = $36, we find that David raised $12.
Explanation:To find out how much David made in the walk-a-thon, we need to break down the information given. We know that all three individuals together made $46, with Leslie making $10. So, David and Chen together made $46 - $10 = $36. But we are also told that Chen made twice as much as David. If we represent David's earnings as 'x', then Chen's earnings would be '2x'. Therefore, 2x (Chen's earnings) + x (David's earnings) equals $36.
Adding 2x and x gives 3x, so the equation to solve is 3x = $36. To solve for 'x', divide both sides of the equation by 3. This gives x = $36 / 3, so David's earnings, represented by 'x', is $12.

Your football team has a probability of 3/4 or 75% of winning a game. Your team is scheduled to play 16 games. How many games will your team win?
A:10
B:12
C:14
Answer:
B. 12
Step-by-step explanation:
3/4 can be converted to something over 16. You have to multiply 4 x 4 to get to 16, so do the same with 3, and 3 x 4 is 12. Now the fraction/proportion is 12/16, so they will win 12 games.
Answer:
B
Step-by-step explanation:
3/4 of 16 is 12 set a relation 3/4 = x/16. 4 x 4 is 16 so multiply 3 x 4 and you get 12 or you can ask siri "what is 75 percent of 16"

Answer:
40 and a half feet
Step-by-step explanation:
1 meter=3 feet

The runner will run about 40.5 ft
What is unit conversion?A unit conversion expresses the same property as a different unit of measurement.
For instance, time can be expressed in minutes instead of hours, while distance can be converted from miles to kilometers, or feet, or any other measure of length.
Given that, a football player runs 13 1/2 yards we need to find the that, how many feet does he run,
Since,
1 meter = 3 feet

value by about 6% per year, how much will it be worth after 15 years?
a $22.992
b
$11,219
C $17,431
$29,647
Answer:
Option D. $29,647
Step-by-step explanation:
The following were obtained from the question:
Present value = $75,000
Rate of depreciation (R) = 6%
Time (t) = 15 years
Amount after 15 years =?
Since the worth of the tractor is depreciating, we shall apply the following formula to obtain the worth after 15 years:
Amount = present value x (1 – R)^t
Amount = $75000 x (1 – 6%)^15
Amount = $75000 x (1 – 0.06)^15
Amount = $75000 x (0.94)^15
Amount = $29647
Therefore, the value of the tractor after 15 years is $29647

What is the Measurement of angle A?
Answer:
A = 60
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
119 = 3y+14 + 4y
Combine like terms
119 = 7y+14
Subtract 14 from each side
119-14 = 7y+14-14
105 = 7y
Divide each side by 7
105/7 = 7y/7
15 = y
We want to find Angle A
A = 4y
A = 4*15
A = 60
