Step-by-step explanation:

Using the concept of percentage, we can deduce that Kareem does not have enough money with him

To solve the questions given, we need to apply the concept of percentage on some.

a) Rounding the price of the guitar to a convenient amount, we get $180.

b) 10% of the rounded price is: 0.1 x $180 = $18.

c) 1% of the rounded price is: 0.01 x $180 = $1.80.

d) To get the estimated tax, we need to multiply the rounded price by the HST rate: 0.13 x $180 = $23.40. Dividing this by $1.80, we get approximately 13.

e) The estimated tax is $23.40.

f) Adding the estimated tax to the rounded price, we get $180 + $23.40 = $203.40.

Since Kareem has $200 cash with him, he does not have enough money to buy the guitar at the estimated price of $203.40. Therefore, the answer is NO.

"To round the decimal number 285.429 to the nearest tenth, we need to look at the digit in the hundredths place, which is 2.

If the digit in the hundredths place is 5 or greater, we round up the digit in the tenths place. If it is less than 5, we leave the digit in the tenths place as it is.

In this case, the digit in the hundredths place is 2, which is less than 5. Therefore, we leave the digit in the tenths place as it is, which is 2.

So, rounding 285.429 to the nearest tenth gives us:

285.4

Therefore, the rounded value of the decimal number 285.429 to the nearest tenth is 285.4." (ChatGPT, 2023)

Step-by-step explanation:

A fraction is a fragment of a whole number, used to define parts of a whole. The whole can be a whole object, or many different objects. The number at the top of the line is called the numerator, whereas the bottom is called the denominator.

To solve for which type of book covers the most space, we need to first convert 25% from a percentage to a fraction.

A percentage is a ratio, or a number expressed in the form of a fraction of 100. Percentages are often used to express a part of a total.

If percentages are fractions of 100, then 25% as a fraction would look like this:

We can do the same to 0.3, although it isn't a percentage.

Now, we need to convert the fractions ([tex]\frac{25}{100}[/tex], [tex]\frac{30}{100}[/tex], [tex]\frac{7}{20}[/tex]) to have a common denominator.

A common denominator consists of two or more fractions that have the same denominator. This makes it easier to perform numeric equations, and to solve them.

To make [tex]\frac{7}{20}[/tex] have a denominator of 100, we can multiply the 20 by 5 to get 100.

Now the fraction is [tex]\frac{35}{100}[/tex].

The three fractions given are:

The larges given fraction is [tex]\frac{35}{100}[/tex] meaning that the children's books cover the most shelf space in the store.

The inequality expression g - 17 ≥ 17 when solved has a solution of g ≥ 34

Given the inequality expression

g - 17 ≥ 17

To solve the inequality g - 17 ≥ 17, we need to isolate the variable g on one side of the inequality.

We can do this by adding 17 to both sides of the inequality:

g - 17 + 17 ≥ 17 + 17

Simplifying, we get:

g ≥ 34

So the solution to the inequality is all values of g that are greater than or equal to 34.

We can graph this solution on a number line by placing a closed circle at 34 and shading to the right, to indicate that any value greater than or equal to 34 satisfies the inequality.

Answer:

1 product

Step-by-step explanation:

Given the equation that shows how the time required to complete an online shopping transaction is related to the number of products being purchased as;

t = 24p + 27

t represents the time required to complete the transaction

p is the product purchased

If it takes 51 seconds to complete a transaction, to get the amount of product purchased, we will substitute t = 51 into the expression and find p as shown;

51 = 24p + 27

Substract 27 from both sides

51-27 = 24p + 27 - 27

24 = 24p

24p= 24

p = 24/24

p = 1

Hence only 1 product is being purchased

Answer:

  C'(-5, -2)

Step-by-step explanation:

You want the coordinates of point C(4, 1) after rotation 90° CW about the origin and translation by (-6, 2).

The transformation accomplished by rotation 90° clockwise is ...

  (x, y) ⇒ (y, -x)

The translation by (-6, 2) adds those values to the coordinates:

  (x, y) ⇒ (x -6, y +2)

Combined, the transformations give you ...

  (x, y) ⇒ (y -6, -x +2)

  C(4, 1) ⇒ C'(1 -6, -4 +2) = C'(-5, -2)

The coordinates of C after the transformation(s) are (-5, -2).

Answer:

      5x^2 - 19x + 15

Step-by-step explanation:

We must multiply the pool's length and width to determine its area. We can factor the equation f(x)=(x-3)(5x+2) to determine the length and width:

f(x) = (x-3)(5x+2)

f(x) = 5x^2 - 13x - 6

One of the parameters is the pool's length (x-3), while the other is its breadth (5x+2). We multiply these two elements to determine the area:

Area is length times width (x-3)

(5x+2)

By extending this statement using FOIL (First, Outer, Inner, Last), we may make it simpler:

Area is equal to  5x^2 - 13x - 6x + 15

Area: 5x^2 - 19x + 15

The pool at Philip and Laura's home is therefore  5x^2 - 19x + 15 square feet in size. We are unable to establish the precise square footage of the pool because we were not given a specific figure for x.

The correct option to determine the value of volume of solid figure is: B. 10 × 3 × 6 and 4 × 3 × 6.

One of the three-dimensional shapes that can be created with six pairs with parallel lines is a rectangular prism. Three-dimensional shapes in this category include cubes and cuboids. Prisms come in a variety of classifications based on the base.

Assuming that there are no other transactions or fees on the credit card, here's how to calculate the unpaid balance, new interest, and purchasing power on the credit card after the minimum monthly payment is made:

1.) Unpaid Balance: The unpaid balance is the amount of the credit card balance that remains after making the minimum monthly payment. In this case, the minimum monthly payment is $125, so the unpaid balance would be:

$5000 - $125 = $4875

2.) Interest Charge: The interest charge for unpaid balances is 18% per year. To calculate the monthly interest rate, divide the annual rate by 12:

18% / 12 = 1.5%

3.) To calculate the interest charge for the month, multiply the unpaid balance by the monthly interest rate:

$4875 x 1.5% = $73.13

So the new interest charge for the month is $73.13.

4.) Purchasing Power: Purchasing power refers to the amount of credit that is available on the credit card after making the minimum monthly payment and accounting for any interest charges. To calculate the purchasing power, subtract the unpaid balance and interest charge from the credit limit:

$5000 - $4875 - $73.13 = $51.87

So the purchasing power on the credit card after the minimum monthly payment is made is $51.87.

Answer:

80

Step-by-step explanation:

The variable "n" is not defined, but rather "k" is used in the summation. Assuming that "n" was meant to be "k", the expression should be:

s4 = ∑ k=1 to 4 of 2(3^(k-1))

To evaluate this expression, we need to substitute each value of k from 1 to 4 into the expression 2(3^(k-1)), and then sum up the results.

Starting with k = 1:

2(3^(1-1)) = 2(3^0) = 2(1) = 2

Moving on to k = 2:

2(3^(2-1)) = 2(3^1) = 2(3) = 6

Next, k = 3:

2(3^(3-1)) = 2(3^2) = 2(9) = 18

Finally, k = 4:

2(3^(4-1)) = 2(3^3) = 2(27) = 54

Now we add up these four results:

s4 = 2 + 6 + 18 + 54 = 80

Therefore, the value of s4 is 80.

The inverse function of f(x) = (x + 5)² on the domain x >= -5 is given as follows:

[tex]f^{-1}(x) = \sqrt{x} - 5[/tex]

The domain of the inverse function is given as follows:

x >= 0.

The function for this problem is defined as follows:

f(x) = (x + 5)² on the domain x >= -5.

The range of the function is y >= 0, as the vertex is at (-5,0) and the function is increasing over it's domain, hence the domain of the inverse function, which is the range of the original function, is given as follows:

x >= 0.

To obtain the inverse function, wee exchange x and y in the definition of the function, and then isolate y, hence:

x = (y + 5)²

[tex]y + 5 = \sqrt{x}[/tex]

Answer:

First question:

We can start by setting up the formula that relates the volume V, temperature T, and pressure P:

V = k * (T/P)

where k is a constant of proportionality. We can solve for k by plugging in the given values for V, T, and P:

70 = k * (420/18)

Simplifying the right side of the equation, we get:

70 = k * 23.3333

Dividing both sides by 23.3333, we get:

k = 3

Now we can use this value of k to find the temperature T when V is 60 cm and P is 7:

60 = 3 * (T/7)

Simplifying the equation, we get:

T/7 = 20

Multiplying both sides by 7, we get:

T = 140

Therefore, the temperature when V is 60 cm and P is 7 is 140 kelvin.

Second question: We can start by using the formula that relates the time (T), distance (D), and speed (S):

D = S * T

Since the distance between the two cities is constant, we can set the distances for the two cars to be equal:

35 * 9 = 21 * T

Simplifying the right side of the equation, we get:

315 = 21T

Dividing both sides by 21, we get:

T = 15

Therefore, the trip takes 15 hours for a car moving at 21 mph.

Using square process method, we can get the values of x to be 12 and 6.

The formula a (x + m)2 + n = a (x + m)2 + n is the simplest to remember while learning how to complete the square technique.

The following formulas can be used to compute m and n in this situation: m = b/2a and n = c - (b2/4a).

From the question,

x² - 18x + 72= 0

⇒ x² - 18x = -72

Complete the square by adding the half of the square of the coefficient of x to both sides of the expression as shown:

⇒ x² - 18x + (18/2) ² = -72 + (18/2) ²

⇒ x² - 18x + 9² = -72 + 81

⇒ (x-9) ² = 9

⇒ x-9 = ± 3

So, values of x are:

x = 3 + 9

= 12

x = -3 + 9

= 6

Therefore, the values of x are 12 and 6.

Is sin (θ) = - 2/ 3, the options that are possible include:

Since sec(θ) is negative, cos(θ) is also negative (sec(θ) = 1/cos(θ)). This means θ is in the second or third quadrant, but since sin(θ) is negative, θ must be in the third quadrant. Now let's check if the given tan(θ) value is correct:

tan(θ) = sin(θ)/cos(θ)

Since we already know that cos(θ) is negative, we have cos(θ) = -(√5)/3.

Now calculate tan(θ):

tan(θ) = (-2/3) / (-(√5)/3) = 2/√5

The height of the cylinder is approximately 42/11 inches. The answer is option C.

What is the formula for the volume of the cylinder?

The formula for the volume of a cylinder is V = πr²h, where V is the volume, r is the radius, and h is the height.

We are given that the volume of the cylinder is 1 and one-third in^3 and the radius is one-third in. Substituting these values into the formula, we get:

1 and one-third = 4/3

V = π(1/3)²h = 4/3

Simplifying the equation, we get:

h = (4/3) / (π(1/3)²) = (4/3) / (π/9) = (4/3) * (9/π) = 12/π

Approximating π as 22/7, we get:

h ≈ (12/π) ≈ (12/(22/7)) = 42/11 inches

Therefore, the height of the cylinder is approximately 42/11 inches. The answer is option C.

Answer:

Step-by-step explanation:

In quadrilateral ABCD, we have:

AB is parallel to DC

AD is parallel to BC

AC = 40 in (given)

BD = 50 in (given)

AB = 25 in (given)

We can use the fact that opposite sides of a parallelogram are equal in length to find the length of CD:

CD = AB = 25 in

Next, we can use the fact that the diagonals of a quadrilateral bisect each other to find the length of AO and OC:

AO = BO = BD/2 = 50/2 = 25 in

OC = OD = AC/2 = 40/2 = 20 in

Now we can use the triangle inequality to find the perimeter of triangle COD:

CO + OD + CD > OC

CO + 20 + 25 > 20

CO + 45 > 20

CO > -25

CO + OC > CO

CO + 20 > 0

CO > -20

CO + CD > OD

CO + 25 > 20

CO > -5

Therefore, the possible range of values for CO is:

-20 < CO < -5

However, since lengths cannot be negative, we can take the absolute value of CO to get:

5 < CO < 20

So the perimeter of triangle COD is:

CO + OD + CD = CO + 20 + 25 = CO + 45

Substituting the possible range of values for CO, we get:

5 + 45 < CO + 45 < 20 + 45

50 < CO + 45 < 65

So the perimeter of triangle COD is between 50 in and 65 in.

Therefore, the perimeter of triangle COD is between 50 in and 65 in, but the exact value depends on the length of CO, which is between 5 in and 20 in.
