Answer:

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.

Option A

Answer:  

[tex]\frac{36}{54} \text { and } \frac{6}{9}[/tex] are proportional.

Solution:

If two fractions are equal, than it is said to be in proportion.

Case 1:  

Consider option A

Given fractions are [tex]\frac{36}{54} \text { and } \frac{6}{9}[/tex]

[tex]\frac{36}{54}=\frac{9 \times 2 \times 2}{9 \times 2 \times 3}=\frac{2}{3} \text { and } \frac{6}{9}=\frac{2 \times 3}{3 \times 3}=\frac{2}{3}[/tex]

Hence both the fractions are equal. So they are propotional.

Case 2:

Consider option 2

Given fractions [tex]\frac{6}{7} \text { and } \frac{16}{21}[/tex] cannot be simplified further. Also both the fractions are not equal. So they are not propotional.

Case 3:

Consider option 3

Given fractions are [tex]\frac{21}{36} \text { and } \frac{21}{42}[/tex]

[tex]\frac{21}{36}=\frac{7 \times 3}{6 \times 6}=\frac{7}{12} \text { and } \frac{21}{42}=\frac{7 \times 3}{6 \times 7}=\frac{1}{2}[/tex]

Hence [tex]\frac{7}{12} \text { and } \frac{1}{2}[/tex] are not equal. Hence they are not propotional.

Case 4:

Consider option 4  

Given fractions are [tex]\frac{14}{35} \text { and } \frac{21}{42}[/tex]

[tex]\frac{14}{35}=\frac{7 \times 2}{7 \times 5}=\frac{2}{5} \text { and } \frac{21}{42}=\frac{7 \times 3}{7 \times 6}=\frac{1}{2}[/tex]

Hence [tex]\frac{2}{5} \text { and } \frac{1}{2}[/tex] are not equal. Hence they are not propotional.

The answer for the given question is option A  

Answer:

X=0

Step-by-step explanation:

Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.

3(x+1)+x=2(x−3)+93(x+1)+x=2(x-3)+9

Simplify the left side.

4x+3=2(x−3)+94x+3=2(x-3)+9

Simplify 2(x−3)+92(x-3)+9.

4x+3=2x+34x+3=2x+3

Move all terms containing xx to the left side of the equation.

2x+3=32x+3=3

Move all terms not containing xx to the right side of the equation.

2x=02x=0

Divide each term by 22 and simplify.

To find the measure of angle ACD, subtract the measures of angles ABC and BCD from 180 degrees.

To find the measure of angle ACD, we need to subtract the measures of angles ABC and BCD from 180 degrees since the sum of the angles in a triangle is always 180 degrees.

Given that angle ABC measures 117 degrees and angle BCD measures 33 degrees, we have:

∠ACD = 180 degrees - 117 degrees - 33 degrees

= 147 degrees.

Answer:

A.  4ab^2.

Step-by-Step Explanation.

12 a^3 b^6  c^5 / 3 a^2 b^4 c^5

Dividing each pairs of terms:

12 / 3 = 4.

a^3 / a^2 =  a.

b^6 / b^4 =  b^2.

c^5 / c^4 =  1.

So it is 4ab^2.

The length of one side of the region containing the small squares is 64 inches.

Let x be the length of one side of the region containing the small squares.

The area of the small squares is 64 * 1 = 64 square inches.

The area of the border is (x + 2)^2 - x^2 = 4x + 4 square inches.

Since the area of the small squares and the border is equal to the area of the chessboard, we have:

64 + 4x + 4 = 324

68 + 4x = 324

4x = 256

x = 64

Therefore, the length of one side of the region containing the small squares is 64 inches.

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

y  = 10 -6

y = 4

Step-by-step explanation:

the formula to find slope with two points is y2-y1/x2-x1.

for this problem it would be solved as follows:

1-3/4-3

-2/1 = -2

The slope of a line is the change in the y values over the corresponding x values.

The slope of the line that passes through (3, 4) and (4,1) is -3

Given that:

[tex](x_1,y_1) = (3,4)[/tex]

[tex](x_2,y_2) = (4,1)[/tex]

The slope (m) is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

So, we have:

[tex]m = \frac{1-4}{4-3}[/tex]

[tex]m = \frac{-3}{1}[/tex]

[tex]m = -3[/tex]

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.

Final answer:

Translate the verbal statement into an inequality, 9 + 2w ≤ 27, then solve for w by subtracting 9 and dividing by 2 to find w ≤ 9.

Explanation:

The statement 'Nine increased by the product of a number and 2 is less than or equal to 27' can be translated into the following inequality: 9 + 2w ≤ 27, where w represents the unknown number. To solve for w, we will follow these steps:

Subtract 9 from both sides: 2w ≤ 18.

Divide both sides by 2: w ≤ 9.

Therefore, the solution to the inequality is w being any number less than or equal to 9.

Answer:

He would to jog 5 miles to go direct to his home

Step-by-step explanation:

* Lets explain how to solve the problem

- Charlie jogs 3 miles south and then 4 miles west

- We need to know if Charlie were to jog straight home, without

 changing direction how far he have to jog

- Remember: the East-west line is perpendicular to the north-south line

∵ He jogs 3 miles south

∵ He jogs 4 miles west

∵ South ⊥ west

- We can consider that the west and east distance with the straight

 distance to home formed a right triangle its legs are the south and

 west distance and the straight distance is its hypotenuse

∴ By using Pythagoras Theorem we can find the straight distance

- Remember: In Pythagoras Theorem [tex]c=\sqrt{a^{2}+b^{2}}[/tex]

 where c is the hypotenuse , a and b are the legs of the right Δ

∴ The straight distance = [tex]\sqrt{(3)^{2}+(4)^{2}}\sqrt{9+16}=\sqrt{25}=5[/tex]

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:

6 × 10 × 10 ×10 × 10 = [tex]6 \times 10^{4}[/tex]

Step-by-step explanation:

The exponent of any number shows that how many times that number can be used in multiplication. It is the power raised to any number which show the number of times that number is raised by.

6 × 10 × 10 ×10 × 10

Here 10 is multiplied 4 times, therefore the exponent of 10 is 4.

∴ 6 × 10 × 10 ×10 × 10 = [tex]6 \times 10^{4}[/tex]

Final answer:

The expression 6X10X10X10X10 written with an exponent is 6x10⁴, indicating that 10 is multiplied by itself four times and then multiplied by 6.

Explanation:

To write 6X10X10X10X10 with an exponent, we identify the repeated multiplication of 10s. Since there are four 10s multiplied together, we use the exponent 4 to represent this, and the expression becomes 6x10⁴. This is because when you have repeated multiplication of the same number, you can express that number raised to the power of how many times it is multiplied by itself.

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.
