Every five years in February, the population of a certain town is recorded. In 1995, the town had a population of 6,500 people. From 1995 to 2000, the population increased by 8%.

Answers

Answer:

R=110 degrees

B=110 degrees

Step-by-step explanation:

R and B are the same angle, we minused the mesure of G and since angle O is same as the other angle we multiplied 60 by two and then added 20 which gave us 140

360-140=R+B

220=R=B

110=R

110=B

Answer:

m<R = 120 degrees, m<B = 100 degrees

Step-by-step explanation:

1. i found the blue line and the angle of any line is 180 degrees

2. since angle O is 60 you have to subtract it from 180 -60 = 120 = m<R.

3. this one is more complicated you have to subtract angle O and angle G which is 20 degrees so you add 20 + 60 = 80 and then you take the sum and subtract it from 180: 180 - 80 = 100

Harper only has $15 to spend at the grocery store. She buys Doritos that cost $2 per bag and one sandwich for $8. Which solution set would represent the options for the number of bags of Doritos she can buy.

Answers

Answer:

2x + 8 ≤ 15

Step-by-step explanation:

Hi,

2x represents the cost for each bag of doritios. The 8 is the cost of the sandwitch. And 15 is how much money she can spend :)

Answer:

2d + 8 ≤ 15

Step-by-step explanation:

Let the amount of Doritos bags be represented by d.

2d + 8 ≤ 15

With this, we can solve.

2(3) + 8 ≤ 15

6 + 8 ≤ 15

14 ≤ 15

The equation is true, and we cannot go any further.

The answer is ≤ 3.

Simplifying x = 3x + -8 Reorder the terms: x = -8 + 3x Solving x = -8 + 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-3x' to each side of the equation. x + -3x = -8 + 3x + -3x Combine like terms: x + -3x = -2x -2x = -8 + 3x + -3x Combine like terms: 3x + -3x = 0 -2x = -8 + 0 -2x = -8 Divide each side by '-2'. x = 4 Simplifying x = 4

Find the distance between each pair of points

Answers

Answer:

4: (0, 4)

5: (0, 8.8)

6: (0, 6)

7: (10, 0)

Step-by-step explanation:

6-2=4

5.5-(-3.3)=8.8

-7/12-(-1/2)

31/4-(-9/4)=10

The distances between the points are:

4) 45) 8.86) 67) 10How to find the distances between the points?

The distance between two points (a, b) and (c, d) is given by:

[tex]distance = \sqrt{(a - c)^2 + (b - d)^2}[/tex]

4) Here the points are (-5, 2) and (-5, 6) so the distance is:

[tex]distance =\sqrt{(-5 - (-5))^2 + (6 - 2)^2} = 4[/tex]

5) Here the points are (4.5, -3.3) and (4.5, 5.5), so the distance is:

[tex]distance = \sqrt{(4.5 - 4.5)^2 + (-3.3 - 5.5)^2 } = 8.8[/tex]

6) Here the points are (5 + 1/2, -7 - 1/2) and (5 + 1/2, -1 - 1/2), so the distance is:

[tex]distance = \sqrt{(5.5 - 5.5)^2 + (-7.5 - (-1.5)^2)} = 6[/tex]

7) Here the points are (-2.25, -8) and (7.75, -8), so the distance is:

[tex]distance = \sqrt{(-2.25 - 7.75)^2 + (-8 + 8)^2} = 10[/tex]
