Answer:

x = [tex]\frac{+}{-}[/tex] 7

Step-by-step explanation:

[tex]x^{2}[/tex] = 49

[tex]\sqrt{49}[/tex] can equal 7 or -7

7 x 7 = 49.  -7 x -7 = 49

Suri made the error of only finding one solution for the equation x squared = 49. The correct solutions are x = 7 and x = -7.

Suri made an error when solving the equation x squared = 49 by only finding one value for x. In fact, there are two solutions to this equation, as the square root of 49 can be both positive and negative. So the correct solutions are x = 7 and x = -7.

+140.68 m/h

Step-by-step explanation:

17.33 h

2438.1/17.33 = 140.68

+140.68 m/h

Final answer:

The woman's average flight speed is 140.7 miles/hour, calculated by using the formula for speed (v = d/t) on the provided distance (2438.1 miles) and the converted time (17 hours 20 minutes to 17.333 hours).

Explanation:

Calculating Average Speed

The question is asking to calculate the average speed of a woman's flight given the distance traveled and the time taken. To convert the time from hours and minutes to just hours, we use the fact that 20 minutes is ⅓ of an hour (20/60). Therefore, 17 hours 20 minutes is equivalent to 17 + ⅓ = 17.333 hours.

We use the formula for speed, v = d/t, which tells us that speed (v) is the distance (d) divided by the time (t). Plugging in the given values:

Distance (d) = 2438.1 miles

Time (t) = 17.333 hours

Applying these values to the formula gives us:

v = 2438.1 miles / 17.333 hours = 140.7 miles/hour.

So, the final answer is that the woman's average speed during her flight was 140.7 miles/hour.

Answer:

The location of the sum is 2 units before P (left to P)

Step-by-step explanation:

* Lets describe the number line

- A number line is a horizontal straight line with numbers placed at

 an equal units

- A number line can be extended infinitely to the left and to the right

- A number line represents both positive and negative integers

- The numbers come on it from left to right

- The negative numbers come on the left of zero and the positive

  numbers come on the right of zero

- Ex: -5 , -4 , -3 , -2 , -1 , 0 , 1 , 2 , 3 , 4 , 5 part of the numbers on the

 number line

- To add numbers on the number line we start from first number of

  the addition and if this number is added by a positive number we

  go to right , if the number is added by a negative number

  we go to left

- Ex: 5 + 3 ⇒ go from 5 to the right 3 units, then your position is at 8

 2 + (-3) ⇒ go from 2 to the left 3 units then your position is at -1

* Now lets solve the problem

- The sum of P + (-2)

∵ Your location is P

∵ You will add P by (-2)

- Negative number means you go to the left

∴ Your position will be before P by two units

∴ The location of the sum is 2 units before P (left to P)

The sum of p + (-2) will always be located to the left of p on a number line.

To describe the location of the sum P+(−2) on a number line, you would start at the point represented by

P and then move 2 units to the left.

This is because adding a negative number is equivalent to moving to the left on the number line.

For example, if P is located at the number 5 on the number line, then

P+(−2) would be located at 5−2=3.

So, the sum is 3 units to the left of the point P on the number line.

to get the inverse of any expression, we start off by simply doing a quick switcheroo on the variables, and then solving for "y".

Answer:

C. The value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Step-by-step explanation:

The average rate of change for the function f(x) from [tex]x_1=a[/tex] and [tex]x_2=b[/tex] is

[tex]\dfrac{f(b)-f(a)}{b-a}[/tex]

It is a measure of how much the function changed per unit, on average, over that interval.

Actually, this is the slope of the line passing through two points on the graph of the function.

If the average rate of change of the function f(x) between m = 36 and m = 60 is -0,04, it means that the value of the comic book decreased (because of negative number -0.04) by an average of $0.04 each month (a unit in this case is a month) between m = 36 and m = 60.

Answer:

C. The value of the comic book decreased by an average of $0.04 each month between m = 36 and m = 60.

Step-by-step explanation:

Answer:

The origin represents no potatoes, thus no money.

The variation is 0.99 per pound.

Step-by-step explanation:

If the price of 3 pounds is $2.97, that means each pound costs $0.99

So, the price of 4 pounds of potatoe, is 4 x $0.99 = $3.96

Same for 6 and 10:

6 x $0.99 = $5.94

10 x $0.99 = $9.90

So, the variation is $0.99 for pound of potatoe

Answer: The unit rate is $0.99.

and the origin represents no potatoes means no money i.e. (0,0).

Step-by-step explanation:

Since we have given the table.

Cost of 3 potatoes = $2.97

Cost of 4 potatoes = $3.96

Since there is direct variation.

So, unit rate would be

[tex]\dfrac{2.97}{3}=\dfrac{3.96}{4}=\$0.99[/tex]

Hence, the unit rate is $0.99.

and the origin represents no potatoes means no money i.e. (0,0).

Angle TSU

Step-by-step explanation:

Two lines extend from point S to create a right angle TSR, where the vertical line extends from point S through point R and the horizontal line extends right from point S through point T.

A third line extends right and up from point S through point U (see attached diagram for details).

Consider angle UST. We can name angles by using three capital letters like: UST. The middle letter is called the vertex of the angle. In your case, the vertex is at S. Two consecutive letters shows the rays which form the angle. In your case, SU (ray from S to U) and ST (ray from S to T) form the angle. If we consider rays ST and SU, then we get angle name TSU.

The way to name angle UST is the angle TSU.

Answer:

he number 7 is a prime number because it can't be divided by any other other number

Step-by-step explanation:

Answer: Prime

Step-by-step explanation: To find out if 7 is a prime or composite number, we can begin by finding the factors of 7.

7 ÷ 1 = 7

This means that 1 and 7 are factors. Notice however that 7 does not divide evenly between 2, 3, 4, 5, or 6. The only other number that 7 divides by evenly is 7. When we divided 7 by 7, we get 1. Notice however that 7 and 1 are repeat factors so we can stop. This means that the factors of 7 are 1 and 7. When a number only has 2 factors, it's called a prime number. Therefore, 7 is considered a prime number.

After converting all volumes to the same unit (milliliters), we can compare them. Sammy's bucket holds 2,530 milliliters, Marie's bucket holds 2,030 milliliters, and Katie's bucket holds 2,350 milliliters. Therefore, Marie's bucket holds the least amount of water.

To answer this question, we first need to convert all the volume measurements to the same unit. In this case, we'll convert everything to milliliters. We know that 1 liter equals 1000 milliliters. Therefore, Marie's bucket holds 2,030 milliliters (2 liters equal 2000 milliliters plus 30 milliliters), and Katie's bucket holds 2,350 milliliters (2 liters equal 2000 milliliters plus 350 milliliters).

Now that all the volumes are in the same units, we can compare them. Sammy's bucket holds 2,530 milliliters, Marie's bucket holds 2,030 milliliters, and Katie's bucket holds 2,350 milliliters.

From this comparison, we can see that Marie's bucket holds the least amount of water.
