Answer:
x = 2.8
Step-by-step explanation:
x/7 = 0.4
multiply both sides by 7
0.4*7 = 2.8
x = 2.8
Answer:
33.2444...
Step-by-step explanation:
The rate of charge is $22 per 90 feet, so first we need to find out how many feet the perimeter takes up. To find the perimeter, we distribute 2 to both sides will adding them. 2(20 + 38) The 2 is there since that only covers 2 out of the 4 lines of a rectangle. Now we do the math as mentioned. 2(30 + 38)
The answer to that would be 136 feet. Now to figure out the cost, we use 22 to see how many 90's can fit into 136 so we can get the rate needed, which is (1.511111..). Thats how many times 90 goes into it, and for every 90 feet, we pay $22, So now we multiply 1.51111 by 22 to get the answer. (33.244444)
Answer:
(-4,-8)
Step-by-step explanation:
You subtract 9 from the x coordinate because that it the coordinate that moves the point left or right.
5-9=-4
A great way to organize this would be to make a t-chart!

In order to answer this question, we use the concept of ratio and proportion wherein we use the equation,
R1 / T2 = R2 / T1
where R is for rate and T is for time. Substituting the known values to the equation,
(600)/x = (400)/ 20
The value of x from the equation is 30. Thus, it will take 30 hours if the rate was adjusted to 400 gallons per minute.
