Answer:

[tex]6\frac{1}{2}[/tex] hours more.

Step-by-step explanation:

We have been given that Linda planned to spend 9 hours practicing piano this week. By Tuesday, she had spent 2 1/2 hours practicing.

To find number of hours Linda needs to practice to reach her goal, we will subtract 2 1/2 from 9 as:

[tex]9-2\frac{1}{2}[/tex]

Convert mixed fraction into improper fraction:

[tex]2\frac{1}{2}\Rightarrow \frac{2\times 2+1}{2}=\frac{4+1}{2}=\frac{5}{2}[/tex]

[tex]9-2\frac{1}{2}\Rightarrow 9-\frac{5}{2}[/tex]

[tex]\frac{9*2}{2}-\frac{5}{2}[/tex]

[tex]\frac{18}{2}-\frac{5}{2}[/tex]

Combine numerators:

[tex]\frac{18-5}{2}[/tex]

[tex]\frac{13}{2}[/tex]

[tex]6\frac{1}{2}[/tex]

Therefore, Linda needs to practice [tex]6\frac{1}{2}[/tex] hours more to reach her goal.

Linda needs to practice for 7 hours and 30 minutes more to reach her 9-hour goal. She's already practiced for 2 1/2 hours, so subtracting this from the total planned practice time of 9 hours gives us the remaining time needed.

Linda planned to spend a total of 9 hours practicing piano this week. By Tuesday, she had already spent 2 1/2 hours on her practice. To find out how much more time she needs to practice to reach her goal, we subtract the time she has already practiced from the total planned practice time.

Here's the step-by-step calculation:

Write down the total number of hours planned for practice: 9 hours.

Write down the number of hours already practiced: 2 1/2 hours.

Convert the 1/2 hour into minutes to make the subtraction easier: 2 hours + 30 minutes.

Now subtract the hours and minutes separately: (9 hours - 2 hours) = 7 hours. Then subtract the minutes, but since there are no minutes in 9 hours, it remains the same: 30 minutes.

So, Linda needs to practice for 7 hours and 30 minutes more to reach her 9-hour goal.

Answer:

d) 3x - 1

Step-by-step explanation:

Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOSITE terms of what it really is, so do not forget it. Anyway, here is how it is done:

-3| 3 8 -3

↓ -9 3

__________________

3 -1 0 → 3x - 1

You start by placing the c in the top left corner, then list all the coefficients of your dividend [3x² + 8x - 3]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is, tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 3 in your quotient can be a 3x, then -1 follows right behind it.

The solution for system of equations x-y=6 ,3 x-2 y=22 is x = 10 and y = 4

Solution:

Using substitution method of algebraic equations,

x - y = 6 --------equation 1

3x - 2y = 22 --------equation 2

Multiplying equation 1 by 2, equation 1 becomes

2 x - 2 y = 12

Multiplying equation 2 by -1, equation 2 becomes,

-3 x + 2 y = -22

Solving,

2 x - 2 y = 12

-3 x + 2 y = -22

-x = -10

x = 10

Substitute  x = 10 in equation 1, 10 - y = 6

Question Explanation:

In other words you can write 200,00 using a whole number and a power 10 using scientific notation!

In scientific notation you want a number less than 10 multiplied by 10 to the power of a number.

-----------------------------------

Solution:

200,000 / 10 = 20,000

20,000 / 10 = 2,000

2,000 / 10 = 200

200 / 10 = 20

20 / 10 = 2

I divided 200,000 by 10 five times to get a number less than 10.

So, 5 is going to be the exponent.

Answer:

2 x 10^5

-----------------------------------

Hope This Helped! Good Luck!

200,000 can be expressed as 2 x 10^5 in scientific notation, which helps to simplify handling of large and small numbers by reducing the number of zeros.

To express 200,000 using a whole number and a power of 10, we need to move the decimal place. Start by writing the number as 2 followed by five zeros, or 2,00000. The power of 10 is determined by the number of places we move the decimal. In this case, the decimal is moved 5 places to the left, so we use 10 to the power of 5. Thus, 200,000 can be written as 2 x 105.

This method is known as scientific notation or powers-of-ten notation. It simplifies dealing with very large and small numbers by reducing the number of zeros we have to keep track of. It also makes mathematical operations easier. For instance, when multiplying numbers in this notation, we need to multiply the numbers out front and then add the exponents.

$ 0.68 type →85lb

$ 0.20 type →35lb

Hey!

-----------------------------------------------

Let $0.68 per pound beans be (b)

Let $0.20 per pound beans be (p)

-----------------------------------------------

~Total amount of pounds:

b + p = 120

~Total cost

b + p = 120 × 0.54

b + p = 64.8

~Expression

0.68b + 0.20p = 64.8

~Multiply 10 to both sides

0.68b * 10 + 0.20p * 10 = 64.8 * 10

~Simplify

6.8b + 2p = 648

~Divide 2 to both sides

6.8b/2 + 2p/2 = 648/2

~Simplify

3.4b + p = 324

~Subtract

    3.4b + p = 324

-         b + p = 120

~Simplify

2.4b = 204

~Divide 2.4 to both sides

2.4b/2.4 = 204/2.4

~Value of b

b = 85

~New expression

85 + p = 120

~Subtract 85 to both sides

85 + p - 85 = 120 - 85

~Value of p

p = 35

-----------------------------------------------

My answer is reasonable because 85 + 35 equals 120 pounds.

~If we check

85 * 0.68 = 57.8

35 * 0.2 = 7

57.8 + 7 = 64.8

We get 64.8 which we can say it is correct because if we go back into our work we can see that we used the expression b + p = 64.8 which in this case by checking our work our answer is reasonable.

Final answer:

After 14 months, the total amount paid to both Community Gym and Workout Gym will be the same, at $910 each.

Explanation:

To determine after how many months the total amount paid to both Community Gym and Workout Gym will be the same, we set up two equations representing the total cost for each gym over time. Let's let x represent the number of months. For Community Gym, the total cost is given by $70 + $60x, and for Workout Gym, it's $210 + $50x.

We set these two expressions equal to find the point where the costs are the same: $70 + $60x = $210 + $50x. Solving for x, we subtract $50x from both sides, getting $70 + $10x = $210. Then, we subtract $70 from both sides to get $10x = $140. Finally, we divide by $10 to find that x equals 14. So, after 14 months, the total cost for both gyms will be the same.

To find out what this total amount will be, we substitute x = 14 back into either gym's total cost equation. Using Community Gym's equation: $70 + $60(14) = $70 + $840 = $910. Therefore, after 14 months, the amount paid to both gyms will be $910.

Answer:-1

Step-by-step explanation:

The slope of the line passing through the points (-4,4) and (-6,6) can be calculated using the formula for slope (m = (y2 - y1)/(x2 - x1)). Substituting the provided points into the formula gives m = 2/-2 = -1. Thus, the slope is -1.

To determine the slope of a line passing through the two points (-4,4) and (-6,6), we use the following formula for calculating slope, often associated with the letter 'm':

Where x1, y1, x2, and y2 are the coordinates of the points the line passes through. In this case, (x1, y1) is (-4,4) and (x2, y2) is (-6,6).

these values into the formula:

m = (6 - 4) / (-6 - -4)

this gives us:

m = 2/-2 = -1

So, the slope of the line passing through the points (-4,4) and (-6,6) is -1.

2√17

Step-by-step explanation:

√((8 - 0)² + (2 - 0)²)

√(64 + 4)

√68

2√17

The length of segment AB, where A = (0,0) and B = (8, 2), is calculated using the distance formula, resulting in a length of AB is √68.

To calculate the length of segment AB where A = (0,0) and B = (8, 2), we can use the distance formula derived from the Pythagorean theorem. The distance formula for two points A(x1, y1) and B(x2, y2) in a coordinate plane is the square root of the sum of the squares of differences between corresponding coordinates:

Distance AB = √[(x2 - x1)² + (y2 - y1)²]

Plugging in the coordinates of points A and B, we get:

Distance AB = √[(8 - 0)² + (2 - 0)²] = √[64 + 4] = √68

Therefore, the length of AB is √68, which is the exact length of the segment AB between points A and B.
