Answer:

The inequality that represents how many miles Henry can drive the car is "m <= 550.5". This inequality can be derived by first calculating the total cost of renting the car for 2 days at $39.90 per day and $0.20 per mile. This gives us a total cost of $79.80 for the rental plus $0.20 per mile for the number of miles Henry drives. Since Henry has $150.00 to spend, we can set up the following inequality to represent the maximum number of miles he can drive:

150.00 >= 79.80 + 0.20m

We can then solve for m by subtracting 79.80 from both sides of the inequality and dividing both sides by 0.20, which gives us:

m <= 550.5

Therefore, the inequality that represents how many miles Henry can drive the car is "m <= 550.5". This inequality states that Henry can drive the car for a maximum of 550.5 miles.

Step-by-step explanation:

The expression 0.5 (x + 3) written as a sum is 0.5x + 1.5

From the question, we have the following parameters that can be used in our computation:

0.5 ( x +3)

Write the expression properly

So, we have the following representation

0.5 (x + 3)

Express the brackets as products

So, we have the following representation

0.5 (x + 3) = 0.5 * (x + 3)

Open the brackets using products i.e. distributive property

So, we have the following representation

0.5 (x + 3) = 0.5 * x + 0.5 * 3

Evaluate the products

So, we have the following representation

0.5 (x + 3) = 0.5x + 1.5

Hence, the expression as a sum is 0.5x + 1.5

The logarithm of (789.5) elevated to the power 1/8 is given as follows:

log(789.5)^(1/8) = 0.36216901679.

The logarithm in this problem is defined as follows:

log(789.5)^(1/8).

It has a power, hence the power can be moved to the front of the logarithm expression applying the power rule, as follows:

log(789.5)^(1/8) = 1/8 x log(789.5).

Then a calculator is used to obtain the logarithm of 789.5, which is the number that is elevated to the base 10 to obtain 789.5, hence:

log(789.5) = 2.89735213434.

Thus the numeric value of the logarithmic expression in this problem is calculated as follows:

log(789.5)^(1/8) = 1/8 x log(789.5) = 1/8 x 2.89735213434 = 0.36216901679.

What is confidence interval?

A confidence interval (CI) for an unknown parameter in frequentist statistics is a range of estimations. The most popular confidence level is 95%, but other levels, such 90% or 99%, are occasionally used for computing confidence intervals. The fraction of related CIs over the long run that actually contain the parameter's true value is what is meant by the confidence level. The degree of confidence, sample size, and sample variability are all factors that might affect the width of the CI. A larger sample would result in a narrower confidence interval if all other factors remained constant. A wider confidence interval would also be required by a higher confidence level and would be produced by a sample with more variability.

The equation of the line will be equal to y = -x + 3.

The equation of the line in slope intercept form is expressed as

y = mx + c

where m is the slope of the line, c is the y-intercept and x and y are independent and dependent variables respectively.

We have the equation of the line as y = x + 5 and we need to find equation of line perpendicular to this line. The slope of the line is 1.

If two lines are perpendicular then the relation in their slope is expressed as

m₁ × m₂ = -1 and we have m₁ = 1 and m₂ = m so we get

1 × m = -1

=> m = -1

Now, the equation of the line will be

y = (-1)x + c

Also, the line passes through (1, 2) so on putting these values

2 = -1 + c

=> c = 3

5/4 gallons ⇒ 5/8 fence

x  gallons ⇒ 8/8 fence

x = (5/4)(8/8) / (5/8)

x = ((5*8)/(4*8)) / (5/8)

x = (5/4) / (5/8)

x = (5*8)/(4*5)

x = 40/20

x = 2

Answer:

A. Here are three more equations that are true based on the information you provided:

1. 3w + 2 = 2w + 6

2. 5w - 6 = 4w - 8

3. 7w - 5 = 6w - 7

B. To find the value of 2w, we need to first solve for w in the original equation 7w + 4 = 5w + 12. We can do this by subtracting 5w from both sides of the equation, which gives us 2w + 4 = 12. Then we can subtract 4 from both sides to get 2w = 8. Therefore, the value of 2w is 8.

C. To find the value of w, we can divide both sides of the equation 2w = 8 by 2, which gives us w = 4. Therefore, the value of w is 4.

A  compound inequality 45 ≤ t ≤ 75 which represents the union of all values larger than or equal to 45 minutes and less than or equal to 75 minutes is the time, denoted by the notation t.

The time Mo takes to mow the lawn is between 45 minutes and 75 minutes, inclusive, which means that the time is either 45 minutes, 46 minutes, 47 minutes, and so on, up to and including 75 minutes. This is a range of values that includes all the times from 45 minutes to 75 minutes.

This statement represents a union, which is the combination of two or more sets of values. In this case, the union is the combination of all the values from 45 minutes to 75 minutes.

To write this statement as a compound inequality, you can use the symbols "≥" (greater than or equal to) and "≤" (less than or equal to) to indicate that the time is greater than or equal to 45 minutes and less than or equal to 75 minutes:

45 minutes ≤ t ≤ 75 minutes

The ordered pair which is solution to this system of inequalities is (1.75, -0.0625).

The system of inequalities are 5x−4y≥9 and 6x+8y≤10.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

The intersection consists of the elements that are contained in all of the intervals.

Here, 5x−4y≥9 -------(I) and 6x+8y≤10 -------(I)

Now, y ≤ 5/4 x+(-9/4); y ≤ -3/4 x+5/4

⇒ 5/4 x+(-9/4) ≤ -3/4 x+5/4

⇒ 5/4 x+3/4 x ≤ 5/4+9/4

⇒ 2x≤ 3.5

Substitute x=1.75 in y ≤ 5/4 x+(-9/4), we get
