A number cube will be rolled 100 times as part of an experiment. Which calculation would you use to predict the number of times a 4 will be rolled?

Answer:

The required equation is: [tex]217\times 12=2,604[/tex]

The red car can travel 2,604 Km in 12 hours.

Step-by-step explanation:

Consider the provided information.

It is given that the speed of red car is 217 km\hr

We need to write an equation and find how many kilometers could red car travel in 12 hours.

The required equation is: [tex]217\times 12=2,604[/tex]

Hence, the red car can travel 2,604 Km in 12 hours.

Final answer:

David has $34 in his savings account. This was found by setting up an equation where the amount Jumps has is $21 more than David's amount and then solving for David's savings.

Explanation:

The task is to find out the amount of money David has in his savings account. Let's denote the amount David has as D. According to the information provided, Jumps has $21 more than David, and she has a total of $55 in her savings account. We can set up an equation to model this situation:

D + $21 = $55

To solve for D, we need to subtract $21 from both sides of the equation:

D + $21 - $21 = $55 - $21

D = $34

Therefore, David has $34 in his savings account.

David has $34 in his savings account, which we found by setting up and solving the equation 55 = X + 21, where X represents David's savings.

To find the amount David has in his savings account, we need to set up an equation based on the information provided:

Jumps has $55 in her savings account, which is $21 more than David has. Let's define the amount David has as X. According to the problem, we can write the equation as:

55 = X + 21

To solve for X, we subtract 21 from both sides of the equation:

55 - 21 = X

Which simplifies to:

34 = X

Therefore, David has $34 in his savings account.

The final result is 803.

To evaluate the given expression 53 − (−648) + 102, we need to follow the rules of arithmetic operations, particularly the order of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

First, we look inside the parentheses. Since we have a negative sign before the parentheses, we understand that we are subtracting a negative value which is the same as adding its positive equivalent. So our expression will become 53 + 648 + 102.

Next, we perform the addition operation: 53 + 648 = 701 Adding 102 to 701: 701 + 102 = 803

The final result of evaluating the expression is 803.

Answer: 5 units.

Step-by-step explanation:

Given : Line segment EF has a length of 5 units.    (1)

It is translated 5 units to the right on a coordinate plane to obtain line segment E'F'.

We know that a translation is a rigid transformation that produces images by moving it by some distance in a particular direction . It preserves the shape and the side-length of the figure.

Thus, The length of E'F'=EF  [∵E'F' is the image produced after translation of EF]

⇒ Length of E'F'= 5 units.    [From (1)]

The correct equation that could represent Relationship A, which has a greater rate than Relationship B, is A. y = 16.4x as it is the only rate per hour greater than that of Relationship B's $15.20 per hour.

The student's question concerns comparing rates of pay in two different linear relationships. Given the table for Relationship B, we can calculate the rate per hour for Relationship B and then compare this to the rates provided in the equations for Relationship A. By looking at the data provided for Relationship B, we can see that the rate is constant. For example, for 2 hours worked, the amount paid is $30.40, which results in a rate of $30.40 / 2 hours = $15.20 per hour.

Because Relationship A has a greater rate than Relationship B, we are looking for an equation where the rate (slope) is greater than $15.20 per hour. Therefore, we eliminate any option where the rate is less than or equal to $15.20. Looking at the provided options:

A. y = 16.4x

B. y = 14.9x

C. y = 15.4x

D. y = 15.2x

Since options B ($14.9 per hour), C ($15.4 per hour), and D ($15.2 per hour) have rates that are either less than or equal to the rate of Relationship B, they cannot represent Relationship A which has a greater rate. Therefore, the only possible option is A. y = 16.4x, which represents a rate that is greater than the rate we determined for Relationship B.

Answer:

17

Step-by-step explanation:

Given,

24 - 3 x = -27.

24+27 = 3[tex]x[/tex]

3[tex]x[/tex] = 51

[tex]x[/tex] = [tex]\frac{51}{3}[/tex]

[tex]x[/tex] = 17
