Answer:

(a)Required relation is 393 + 2x ppm

(b)Amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm

(c)After 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm

Step-by-step explanation:

From the question it is given that :

Estimated [tex]CO_2[/tex] in atmosphere in 2012 is 393 (parts per million)ppm

[tex]CO_2[/tex] level increasing per year is 2 ppm

(a) Let y be the concentration of [tex]CO_2[/tex] in atmosphere after x years from 2012 then:

y = 393 + 2x ppm

Therefore required relation is 393 + 2x ppm

(b) amount of [tex]CO_2[/tex] in 2025 i.e.,x = 13 years after 2012 is y

y = 393 + 2 x 13 = 393+ 26 = 419 ppm

Therefore, amount of [tex]CO_2[/tex] concentration in 2025 is 419 ppm

(c) give y = 400 ppm and x be the year then

400 = 393 + 2x

2x = 7

⇒ x = 3.5 years

Therefore after 3.5 years concentration of [tex]CO_2[/tex] is 400 ppm

The second option, 3/4 = 9/12 is a proportion.

Hope this helped! :D

Answer:

B

Step-by-step explanation:

To find the correct proportion you simplify all fractions into their simpliest form. If you do this you'll find that only B has two equivalent fractions

Answer:

#11: last option is answer

#12: first option is answer

Step-by-step explanation:

#11) 5x + 6 ≤ 11

     5x ≤ 5

       x ≤ 1  to graph this you need a solid dot on 1 and shading to the left

#12) 5p+ 4 > 14

       5p > 10

        p > 2  to graph this you need an open dot on 2 and shading to the right

Answer:

11.  5x + 6 <= 11.

12. 5p + 4 > 14.

Step-by-step explanation:

11.  THE GRAPH shows that x <= 1.

So it is 5x + 6 <= 11  because

5x <= 5

x <= 1.

12. THE GRAPH shows that p > 2.

So it is 5p + 4 > 14.

5p + 4 > 14

5p > 10

p > 2.

Answer:

are you sure there isn't a 90?

Step-by-step explanation:

Because  there are 4 quarters in a whole, so 22 x 4 = 88, and there are 2 quarters in 1/2 so it would be 88+2, which is 90.

Answer:

-24

Step-by-step explanation:

25-31=-6

-6 times 4=-24

Answer:

DE = 15 cm, AB = 6 cm

Step-by-step explanation:

Since the triangles are similar then the ratios of corresponding sides are equal.

(a)

[tex]\frac{DE}{BC}[/tex] = [tex]\frac{CE}{AC}[/tex] , substitute values

[tex]\frac{DE}{5}[/tex] = [tex]\frac{24}{8}[/tex] = 3 ( multiply both sides by 5 to clear the fraction )

DE = 15 cm

(b)

[tex]\frac{AB}{CD}[/tex] = [tex]\frac{AC}{CE}[/tex] , substitute values

[tex]\frac{AB}{18}[/tex] = [tex]\frac{8}{24}[/tex] ( cross- multiply )

24AB = 144 ( divide both sides by 24 )

AB = 6 cm

Answer: $1.11

Step-by-step explanation:

we just divide $5.55 (the cost of 5 sandwiches) and divide it by 5. that gives us the cost of 1 sandwich. and, the answer to 5.55 / 5 = 1.11

Answer:

Each sandwich cost $1.11.

Step-by-step explanation:

All you have to do to solve this is divide 5.55 by 5, giving you 1.11.

Given:

A 20 sided dice is rolled.

To find:

The probability of getting 11.

Solution:

A 20 sided dice is rolled.

On a 20 sided dice, the possible outputs are 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20.

Total number of outcomes = 20

Favorable outcomes or number of 11 = 1

Now,

[tex]\text{Probability of getting 11}=\dfrac{\text{Favorable outcomes}}{\text{Total number of outcomes}}[/tex]

[tex]\text{Probability of getting 11}=\dfrac{1}{20}[/tex]

[tex]\text{Probability of getting 11}=0.05[/tex]

Therefore, the probability of getting 11 is 0.05.

Answer:D

Step-by-step explanation:

if we were to round to the nearest thousand you would get 4,7000

Answer:

47000

Step-by-step explanation:

Key skills needed: Rounding and Estimation

1) We have the number 47138

2) We need to round this to the nearest thousand. This means we look at the part that is "7138"

3) We need to see if 7138 is close to 7000 or 8000.

4) It is only 138 away from 7000, but 862 away from 8000.

5) This means 7138 rounded to the nearest thousand is 7000.

6) That means 47138 rounded to the nearest thousand is 47000.

Hope you understood and have a nice day!! :D

Answer:

2.5

Step-by-step explanation:

You can do rise over run and you get 25/10 which is 2.5 or 5/2. So you are correct

Answer:

2.5

Step-by-step explanation:

Slope = change in y/ change in x

In this case the change in y between two spots is 25 and the change in x is 10. So the slope would be 25/10 which can be simplified to 2.5

Hope this helps :D

The value of x in the given system of equation 7+x/3=2x-5 is 7.2.

simultaneous equations, system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods to solving systems of equations: graphing, substitution, elimination and matrices.

Given a System of equation 7+x/3=2x-5

Simplifying this equation

7+x/3=2x-5

=> 2x - x/3 = 12

=> 5x/3 = 12

=> x = 36/5

=> x = 7.2

Therefore, The value of the x for the given Equation is 7.2.

i think it is a but i am sorry if it wrong

Step-by-step explanation:

Answer:

Graph

Step-by-step explanation:

If point P has coordinates (x1, y1) and point Q has coordinates (x2, y2), and PQ is reflected across the X-axis, the coordinates of the reflected points P' and Q' can be obtained by flipping the y-coordinates of P and Q and keeping the x-coordinates the same.

Therefore, the coordinates of P' will be (x1, -y1) and the coordinates of Q' will be (x2, -y2).

So, if you want to find the coordinates of the reflected line segment P'Q', you just need to take the coordinates of P' and Q' and connect them with a line. The resulting line segment will have endpoints (x1, -y1) and (x2, -y2).

Note that the length of the reflected line segment P'Q' will be the same as the length of the original line segment PQ, but the orientation of the reflected line segment will be reversed with respect to the X-axis.

Answer:

Greg needs $2.08 more

Step-by-step explanation:

A gallon of gas costs $4.34. Greg puts 12 gallons of gas in his car. He has a 50-dollar bill.

Hence: The cost of the 12 gallons of gas that Greg bought is given as:

12 gallons × $4.34

= $52.08

Greg has $50

These means Greg would need more Money.

The amount he needs is calculated as:

$52.08 - $50

= $2.08

Greg needs $2.08 more
