543 J of PE?

Answers

Answer 1
PE = mgh
Plug in the values
543 J = m * 9.8 * 10
543 = m * 98
Divide both sides by 98
m = 5.54 kg

D.
10-class pass for $55


E.
$342 for 45 classes

Answer: c. Algorithms are the steps that would be converted into a program that a computer could use to process information, changing it from input to an output.
Explanation: algorithms are steps that is used for data processing. It’s better to think of this as a flow chart. The input (usually from the user) goes in, the algorithm processes the information (this is where the input changes to an output), and spits out the output. This is the best answer out of all the options.

A company called Blurb prints books. According to its advertisement, you get a 15% discount on all orders of 51 or more copies of the same book (up to 100 copies). Is the cost per order a linear function of the number of copies you order (up to 100)?

Answers

Answer:

Yes, the cost per order is a linear function of the number of copies you order (up to 100).

Step-by-step explanation:

Let;

y = Total cost of order from one copy up to 100 copies or dependent variable

a = Cost of 50 copies or fixed intercept

x = Cost of 51 copies or more up to 100 copies or dependent variable, i.e. 51 = x [tex]\leq[/tex] 100

b = Coefficient of x = 1 - Discount rate = 1 - 15% = 1 - 0.15 = 0.85

We can therefore represent have a function as follows:

y = a + bx ........................ (1)

Substituting b = 0.85 into equation (1), we have:

y = a + 0.85x ...................... (2)

Equation (2) implies that as b equal to 51 or more up to 100, y also increases. Equation (2) is therefore an example of linear function which will give an upward sloping straight line and can be rewritten as:

y = f(x) = a + 0.85x ................. (3)

Therefore, the cost per order is a linear function of the number of copies you order (up to 100).

A circular fountain has 132 feet of railing around it. What is the area of the fountain to the nearest square foot? Use 3.14 for π. *

Answers

Answer:

139

Step-by-step explanation:

First we need to find diameter 132/3.14=42 rounded

Then we halve it to find radius 42/2=21

Formula for area is radius x radius x 3.14

21 x 21 = 441 x 3.14 = 138.74 round up is 139

Answer:

18.8 feet, 59.1 feet to the nearest tenth

Step-by-step explanation:

The diameter is the line drawn that divides the circle into two while the circumference is the perimeter of the circle. Both are a measure of the radius of the circle.

The diameter D = 2r where r is the radius of the circle

The circumference = 2Πr = ΠD where Π = 22/7

Given that the circular fountain has a radius of 9.4 feet

Its diameter =  2 × 9.4 feet = 18.8 feet

The circumference = 22/7 × 18.8 feet

=59.09 feet

≈ 59.1 feet to the nearest tenth

Answers

Step-by-step explanation:

9x-7i>9x-21u

-7i>-21u

i<3u

The solution to the given inequality 9x - 7i > 3(3x - 7u) is i < 3u.

Given that:

Inequality: 9x - 7i > 3 (3x - 7u)

To solve the inequality 9x - 7i > 3(3x - 7u), follow these steps:

Step 1: Distribute the 3 on the right side of the inequality as:

9x - 7i > 9x - 21u.

Step 2: Simplify the inequality.

9x - 9x - 7i > - 21u.

Step 3: Rewrite the inequality.

After cancelling out the 9x terms, we are left with -7i > -21u.

Step 4: Divide both sides by -7.

i < 3u

Therefore, the solution to the inequality 9x - 7i > 3(3x - 7u) is i < 3u.

Step-by-step explanation:

The expression that uses the commutative property is 3/5 × 25 × 1/4

What is the commutative property?

The commutative property is a math rule that says that the order in which we multiply numbers does not change the product.

Given is an expression 3/5 × 1/4 × 25

We know that,

The commutative property of multiplication states that:

A × B × C = B × C × A

Using the above equation, we have the result of the commutative property to be:

3/5 × 1/4 × 25 = 3/5 × 25 × 1/4

Hence, the expression that uses the commutative property is 3/5 × 25 × 1/4
