I NEED HELP WITH THIS ASAP PLEASEEE!!!!

Mathematics
1 answer:
Bingel [31]2 years ago
7 0

Answer:

1. Marcia

2. (I do not understand what this question is asking)

3. Marcia's estimation is closer

4. 690 people per year

Step-by-step explanation:

1. Marcia's estimation has a greater number of people because he estimated 600 people per year, while Adam estimated 2% of 12,500 (250 people per year).

2. (I do not understand what this question is asking)

3. marcias guess was 600 (600x50+12,500 = 42,500. 42,500 - 35,400 = 7,100) while Adam's guess was 250 per year (250x50+12,500 = 10,400). Therefore, Marcia's guess was closer to 35,400.

4. If Marcia adjusted her answer so that the population in Burbville was ACTUALLY going to be 34,500, she would need to adjust her estimation to 690 people per year.

Hope this helps! So sorry I couldn't understand question 2!

PLS HELP! which graph is the function 3x + 2y = 8 with the given domain {-2,0,2,4}??
Romashka [77]

Answer:

D

Step-by-step explanation:

Domain of the function 3x + 2y = 8 are the possible set of x-values represented as {-2, 0, 2, 4}.

To know which graph represents the above given function, find the range values of the function by plugging in each value of x into the equation, to find y.

For x = -2,

3(-2) + 2y = 8

-6 + 2y = 8

2y = 8 + 6

2y = 14

y = 14/2

y = 7

(-2, 7)

For x = 0,

3(0) + 2y = 8

0 + 2y = 8

2y = 8

y = 8/2

y = 4

(0, 4)

For x = 2,

3(2) + 2y = 8

6 + 2y = 8

2y = 8 - 6

2y = 2

y = 2/2

y = 1

(2, 1)

For x = 4,

3(4) + 2y = 8

12 + 2y = 8

2y = 8 - 12

2y = -4

y = -4/2

y = -2

(4, -2)

The graph which shows the following set of coordinates pairs calculated above, ((-2, 7), (0, 4), (2, 1), (4, -2)), is the graph of the function 3x + 2y = 8.

Thus, the graph in option D the shows the following calculated coordinate pairs. Therefore, graph D is the answer.

What is the value of x?<br><br> a. 71°<br> b. 142°<br> c. 152°<br> d. 76°
alexgriva [62]
The sum of the measures of the angles of a triangle is 180 degrees.
An isosceles triangle has two congruent sides.
The angles opposite the congruent sides are congruent.
Just like the bottom left angle measures x, the bottom right angle also measures x.

x + x + 38 = 180

2x + 38 = 180

2x = 142

x = 71

Plz give full reasoning
disa [49]

Answer:

r = 12

Step-by-step explanation:

DG + GM = DM , substitute values

r + 3 + 4r - 28 = 35 , that is

5r - 25 = 35 ( add 25 to both sides )

5r = 60 ( divide both sides by 5 )

r = 12
