Given the inequality 4x ≤ 28, which of the following is a solution that makes the inequality true?

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.

Answer:

Step-by-step explanation: the answer is 90

the answer is 3 x 3 x 10 because she has 3 boxes and 30 shells in each box. 30 divided by 3 is 10 therefore you would multiply 3 by 3 to get 9 then multiply 9 times 10 to get 90.

Group 1: 1, 2, 3, 4, 5

Group 2: 6, 7, 8, 9

In this case, the sum of the numbers in Group 1 is 1 + 2 + 3 + 4 + 5 = 15, and the sum of the numbers in Group 2 is 6 + 7 + 8 + 9 = 30. The sum of the numbers in both groups is 15 + 30 = 45, which is the same.

Alternatively, we could create the following two groups:

Group 1: 1, 2, 3, 4

Group 2: 5, 6, 7, 8, 9

In this case, the sum of the numbers in Group 1 is 1 + 2 + 3 + 4 = 10, and the sum of the numbers in Group 2 is 5 + 6 + 7 + 8 + 9 = 35. The sum of the numbers in both groups is 10 + 35 = 45, which is the same.

The exact values for sin(2x), cos(2x) and tan(2x) without solving for x  4√5 /9, -1/9 and -4√5  respectively

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

Therefore, the exact values are given above.

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.

Step-by-step explanation:

So the sales price of the sled is   100%  + 95 % = 195 % of the cost

There is enough storage in the truck. The volume of the septic tank is about 30,164 gallons.

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

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)

The unknown angle in the parallelogram is as follows:

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

∠2 = 155 degrees

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

a) The average rate of change

From 2000 to 2003 = (216- 168)/ 3

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.

An equation is a mathematical statement that shows that two or more mathematical expressions are equal or equivalent.

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
