Answer:

x < 6

Step-by-step explanation:

3x < 18 ( divide both sides by 3 )

x < 6

The cost of the items indicates that the inequality that represents the cost or amount spent is; 18 + 5n ≤ 50, therefore, yes Mai is correct, because the total amount spent depends on the amount with Priya

An inequality is a comparison between two expressions, variables, or quantities that are of different values, using the symbols, '<', '≤', '≠', '≥', and '>'.

The amount Priya has to spend = $50

The cost the gift she finds for her parents = $18

The number of siblings Priya has = 5

Therefore;

The cost of the items she thinks each of her 5 siblings would like = 5 × n

The total cost of the items Priya intends to buy = 18 + 5·n

The inequality that indicates the possibility of Priya buying all the items she finds is therefore;

18 + 5·n ≤ 50

Therefore, May is correct as the amount or the cost of items Priya buys should be less than or equivalent to the $50 Priya has

The batting average for Brett is of 0.25 = 25%.

The batting average is obtained applying the proportions in the context of the problem.

A proportion is applied as the batting average is given by the division of the number of hits by the number of at bats.

Brett got 10 hits in 40 at bats, hence his batting average is calculated as follows:

10/40 x 100% = 0.25 x 100% = 25%.

From the image given at the bottom, we have that he got 10 hits on 40 at bats, hence the batting average calculated above is of 25%.

The length of the golden rectangle is 49 cm.

A rectangle is a quadrilateral (a polygon with four sides) in which each angle is a right angle (90 degrees). It is a type of parallelogram in which opposite sides are parallel and congruent (equal in length). Rectangles have four sides and four vertices (corners).

The length of a rectangle is the distance between its two longer sides, while the width is the distance between its two shorter sides. The perimeter of a rectangle is the sum of the lengths of all its sides, while the area is the product of its length and width.

A golden rectangle has sides in the proportion of the golden ratio, which is approximately 1:1.618. Therefore, if the width is 30cm, the length can be found by multiplying 30 by 1.618.

Length ≈ 48.54 cm

Answer:

To determine which bank is more cost-effective, we need to consider how many transactions we will make per month. Let's call the number of transactions "t".

Bank A charges a flat fee of $45 per month, regardless of how many transactions we make. So the total cost of using Bank A for one month is:

Total cost for Bank A = $45

Bank B charges a monthly fee of $20, plus $0.70 for each transaction. So the total cost of using Bank B for one month is:

Total cost for Bank B = $20 + ($0.70 x t)

To determine which bank is more cost-effective, we need to find the value of "t" that makes the total cost of Bank B equal to the total cost of Bank A.

$45 = $20 + ($0.70 x t)

$25 = $0.70 x t

t = $25 / $0.70

t ≈ 36

So if we make 36 or more transactions per month, Bank A is more cost-effective. If we make fewer than 36 transactions per month, Bank B is more cost-effective.

The term (x - 1) is a factor of both of the given polynomials as;

Given that (x - a) is a factor of a polynomial p(x), then x = a is a zero of the polynomial, which means that:

p(a) =0.

When x - 1 is a factor of any of the given polynomials, then we need to evaluate them in x = 1 and check if we get zero.

a) x² + x - 2

Evaluate it in x = 1;

1² + 1 - 2 = 0

The total area Cydney painted on the display stand is 416 square inches, excluding the bottom of the larger cube.

5. To solve the problem, we need to find the total area that Cydney painted on the display stand.

Plan for solving the problem:

6. Solving the problem:

The surface area of a cube is given by the formula: [tex]6 * (side length)^2[/tex].

For the larger cube:

Surface area of the larger cube =[tex]6 * (8 inches)^2[/tex] = 6 * 64 square inches = 384 square inches.

For the smaller cube:

Surface area of the smaller cube = [tex]6 * (4 inches)^2[/tex]= 6 * 16 square inches = 96 square inches.

Since the bottom of the display stand was not painted, we need to subtract the area of the bottom face of the larger cube:

Area of the bottom face of the larger cube = [tex](side length)^2[/tex] =[tex](8 inches)^2[/tex] = 64 square inches.

Finally, we can calculate the total area Cydney painted by adding the surface area of both cubes and subtracting the area of the bottom face of the larger cube:

Total area painted = (Surface area of the larger cube + Surface area of the smaller cube) - Area of the bottom face of the larger cube

= (384 square inches + 96 square inches) - 64 square inches

= 480 square inches - 64 square inches

= 416 square inches

Therefore, Cydney painted a total area of 416 square inches on the display stand.

The circumference of the given circle is approximately 47.3 inches.

Since the length of the arc KL and the measure of the central angle ∠KOL are known, we can use the formula for arc length to find the circumference of the circle:

arc length = (central angle / 360°) x circumference

Plugging in the known values, we have:

4.6 in = (35° / 360°) x circumference

Solving for the circumference, we get:

circumference = 4.6 in / (35° / 360°)

circumference = 4.6 in x (360° / 35°)

circumference ≈ 47.3 in (rounded to the nearest tenth)

Therefore, the circumference of the circle is approximately 47.3 inches.

The probability that Jannette in Mr. Alsup's sixth-period English class has not chosen a topic for her writing assignment is approximately c.12%. Therefore, option c.12%.  is correct.

To find the probability that Jannette in Mr. Alsup's sixth-period English class has not chosen a topic for her writing assignment, we need to calculate the proportion of students in that class who have not chosen a topic.

From the table, we can see that in the sixth period, there are a total of 25 students. Out of those, 22 students have chosen a topic, and 3 students have not chosen a topic.

The probability can be calculated by dividing the number of students who have not chosen a topic (3) by the total number of students in the sixth period (25), and then multiplying by 100 to get the percentage:

Probability = (Number of students who have not chosen a topic / Total number of students in the sixth period) × 100

Probability = (3 / 25) × 100

Probability ≈ 12%

Therefore, the probability that Jannette in Mr. Alsup's sixth-period English class has not chosen a topic for her writing assignment is approximately 12%.

***For question 6:  Your picture of question 6 is so blurred I could not really make out the angle; I took it as 36° . If it is something else, use the formula given below with the correct angle and compute **

Step-by-step explanation:

[tex]\cos \theta = \dfrac{adjacent}{hypotenuse}\\\\\sin\theta = \dfrac{opposite}{hypotenuse}\\\\\tan\theta = \dfrac{opposite}{adjacent}\\[/tex]

adjacent means side adjacent to θ
opposite means side opposite to θ

adjacent = x

hypotenuse = 10

The z-score of a measure X of a normally distributed variable that has mean represented by [tex]\mu[/tex] and standard deviation represented by [tex]\sigma[/tex] is obtained by the equation presented as follows:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The mean and the standard deviation for this problem are given as follows:

[tex]\mu = 42, \sigma = 11[/tex]

The probability of a value less than 60 is the p-value of Z when X = 60, hence:

Z = (60 - 42)/11

Z = 1.64

Z = 1.64 has a p-value of 0.9495.

Hence the probability of a value greater than 60 is of:

1 - 0.9495 = 0.0505 = 5.05%.

The probability of a value greater than 16 is one subtracted by the p-value of Z when X = 16, hence:

Z = (16 - 42)/11

Z = -2.36

Z = -2.36 has a p-value of 0.0091.

1 - 0.0091 = 0.9909 = 99.09%.

The probability of a value between 16 and 60 is the p-value of Z when X = 60 subtracted by the p-value of Z when X = 16, hence:
