Given the inequality 4x ≤ 28, which of the following is a solution that makes the inequality true?
Answers
For the inequality 4x ≤ 28 the solution that makes the inequality true will be x≤7.
What is inequality?It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
It is given that the inequality is 4x ≤ 28.
Now that the equation has been simplified, we obtain both sides of the inequality equation, divide by 4, and we obtain
x ≤ 7
As a result, x must be less than or equal to 7.
The requirement for x is satisfied by any numbers that are less than or equal to 7.
Thus, for the inequality 4x ≤ 28 the solution that makes the inequality true will be x≤7.

The product of two consecutive odd integers is 99. Find the integers. Answer only with the positive integers. For example, if
the integers are 8, 10 and -8, -10, then answer 8, 10.
Provide your answer below:
n=
n =
Answers
Answer: n= 9 and n=11
Step-by-step explanation:
Assume that x is the lesser of the two numbers. The second figure must be x+2.
Since x*(x+2) = 99, we know that
x^2 + 2x - 99 = 0
We obtain x = 11 and 9 by searching for the roots of this equation.
This can also be resolved in the following ways:
We are aware that the two numbers (x and x +2) are consecutive odd numbers. Since x * (x + 2) = x2 + 2x, the value of x must be near to the square root of 99.
The squares 81 and 100 are the ones closest to the number 99. Additionally, we know that x * (x+2) is bigger than x2 (by a factor of 2x), therefore x must equal 9 and x+2 must equal 11.

Cell phone Plan A costs $80 per month and comes with a free $630 phone. Cell phone Plan B costs $45 per month but does not come with a phone. If you buy the $630 phone and choose Plan B, how many months is it until your cost is the same as Plan A's? Be sure to:
a) Write an equation to represent the situation where x represents the number of months.
b) Show your work to solve the equation from part a using inverse operations.
c) State the answer.
Answers
a) An equation representing the situation where x represents the number of months when Plan A and Plan B cost the same is 80x = 630 + 45x.
b) Using inverse operations, we can state that 80x - 45x = 630 or 35x = 630, and x = 18.
c) From this equation, we determine that x is 18 months.
What is an equation?An equation is a mathematical statement that shows that two or more mathematical expressions are equal or equivalent.
Equations use the equation symbol (=) to depict the equality of the expressions.
Plan A Plan B
Monthly charge $80 $45
Free phone $0 $630
Mathematical Expression:Let Plan A = 0 + 80x
Let Plan B = 630 + 45x
The month the two plans' costs are equal can be derived by equating the two expressions above:
80x = 630 + 45x
80x - 45x = 630
35x = 630
x = 18 months
Thus, solving the equation, we can conclude that choosing Plan B will take 18 months to equal the cost of Plan A and thereafter, be considered cheaper than Plan A.

Answers
0.8926 is the probability that the shipment will be rejected.
What does the math term "probability" mean?
Probability measures how probable something is to occur. We can discuss the probabilities of various outcomes, or how likely they are, whenever we are unsure of how an event will turn out.
Statistics describes the examination of events subject to probability.
The probability that a digital watch is defective p = 10/50 = 0.2
n = 10
Using the binomial probability formula
P(x) = ⁿCₓ pˣ ( 1 - p)ⁿ⁻ˣ
Let x be the random variable that represents the number of defective watches.
The probability that the shipment will be rejected
P(x ≥ 1 ) = 1 - P(0)
= 1 - ¹⁰C₀ ( 0.2)⁰ ( 0.8)¹⁰
= 1 - ( 0.8)¹⁰

The degree of a polynomial is the largest exponent in the function.
When a polynomial has more than one variable, add the exponents of each variable in each term.
3x²y³ has a degree of 5, since both exponents add up to 5.
8x³y⁷ has a degree of 10, since both exponents add up to 10.
So the polynomial has a degree of 10.

There is enough storage in the truck. The volume of the septic tank is about 30,164 gallons.
How to determine if there is enough storage in the truck to drain a full septic tank?Given that:
Your company uses a truck with a storage tank capable of holding 30,500 gallons of waste.
A full septic tank in the shape of a cube measuring 191 inches on each side.
First, calculate the volume of the septic tank:
Volume of septic tank (V) = S³
where S is the side length of the septic tank
S = 191 inches
V = S³
V = 191³ = 6967871 cubic inches
Since we have 231 cubic inches in 1 gallon:
V = 6967871 / 231 = 30,164 gallons
Thus, the capacity of the full septic tank is 30,164 gallons

The exact values for sin(2x), cos(2x) and tan(2x) without solving for x 4√5 /9, -1/9 and -4√5 respectively
How to find the exact values for sin(2x) cos(2x) and tan(2x) without solving for x?Given: cos(x)= 2/3 and x is in quadrant IIn trigonometry, cos(x) = adjacent/hypotenuse = 2/3.
adjacent = 2
hypotenuse = 3
Here, we will find the opposite
opposite =√(3²-2²) = √5
sin(x) = (√5)/3 (opp./hyp.)cos(x) = 2/3
(adj./hyp.)tan(x) = (√5)/2 (opp./adj.)
Using trigonometry identity:
sin(2x) = 2sin(x)cos(x) sin(2x)
= 2× (√5)/3 × 2/3sin(2x)
= 4√5 /9cos(2x) = 2cos²(x) - 1
cos(2x) = 2(2/3)² -1cos(2x) = -1/9
Also, we will find the exact value for tan.
tan(2x) = 2tan(x) / 1-tan²(x)tan(2x) = (2(√5))/2 / 1-((√5)/2)²
tan(2x) = √5 / (-1/4)
tan(2x) = -4√5

Solve the triangle using the Law of Sines. (Assume b and c = 20, and ∠C = 63°. Round the length to two decimal places.)
Answers
Answer:
a = 16.51
angle A = 54
angle B = 63
Step-by-step explanation:
Recall the law of sines:
sinA/a = sinB/b = sinC/c
We know c is 20, and angle C is 63. Since b is also 20, angle B must also be 20. We know have two of the 3 angles, summing to 126, and we can find the last angle from that. 180-126=54, so angle A must be 54.
To solve for a, we need to know the ratio of the other two terms. Sin(63) is around 0.99, and 0.99/20 is 0.049. So we have 0.049=sin(54)/a. To solve for a, we divide by sin(54) and take the reciprocal of both sides, giving a = (sin54)/0.049, which is about 16.51, which is the length of the side a.

The unknown angle in the parallelogram is as follows:
∠2 = 155 degrees.How to find angles of a parallelogram?A parallelogram is a special type of quadrilateral that has both pairs of opposite sides parallel and equal.
In other words, a parallelogram is a two-dimensional geometrical shape whose sides are parallel to each other. Opposite sides are equal in length. Opposite angles are equal. The sum of any two adjacent angles of a parallelogram is equal to 180°
The sum of angles in a parallelogram is 360 degrees.
Therefore,
∠1 = 25 degrees
Hence,
Adjacent angles in a parallelogram are supplementary. This means adjacent angles sum up to 180 degrees.
Therefore,
∠2 + ∠1 = 180
∠2 + 25 = 180
∠2 = 180 - 25
