A utility company measures gas consumption by the hundred cubic feet, CCF. The company has a three-step rate schedule for gas cu

stomers. First, there is a minimum charge of $5.00per month for up to 3 CCF of gas used. Then, for the next 6 CCF, the charge is $0.75 per CCF. Finally, after 9 CCF, the charge is $0.55 per CCF. Represent the cost of g CCF of gas if g is greater than 9.

Answer:

\$(4.65 + 0.55g)

Step-by-step explanation:

Let the number of hundred CCF of gas consumed by the customer =g

\text{When } 0 < g \leq  3\\ \text{Cost =} \$5\\\\\text{When } 3

Therefore, when the hundred cubic feet, CCF of gas consumed is more than 9, the consumer pays for the first 9 and then pays for any subsequent CCF of gas at a rate of $0.55 per CCF

\text{When g}>9  : \text{Cost =} 9.60+0.55(x-9)

=9.60+0.55g-4.95\\=\$(4.65 + 0.55g)

How does soil begin to form?
Nonamiya [84]

Answer:  Rock particles clump together in aggregate

Step-by-step explanation:

Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

Using transformation (x-2 y+3) find the new coordinates of (7 -5) brainly
trasher [3.6K]

Answer:

(5, -2)

Step-by-step explanation:

In the coordinates (7, -5), 7 is the x-coordinate and -5 is the y-coordinate.

The transformation, (x-2 y+3), states that the x-coordinate, 7, must be subtracted by 2.

When subtracted by two, (7 - 2), the difference is 5.

The transformation, (x-2 y+3), states that the y-coordinate must be increased by 3.

When added by 3, (-5 + 3), the sum is -2.

Therefore, the new coordinates are (5, -2).

MArishka [77]
1 hour each day is used for test
so 8-1=7 used per day

so commercial is 1 in the 4:2:1 so
4+2+1=7
ok, so 7 units, 7 hours
4 hour for private
2 hour for research
1 hour of commerical

4*5=20=private
2*15=30=research
1*4=40=commercial


20+30+40=90

percent from commercial
40/90=0.44444444444≈44.44% about 44%

mel-nik [20]

Answer:

x = 25°

Step-by-step explanation:

3x + 2x + x + 30° = 180°

6x + 30° = 180°

6x = 150°

x =25°

=> 3x = 25 * 3 = 75°

=> 2x = 25 * 2 = 50°

=> x + 30° = 25° + 30° = 55°
