A 16 inch candle is lit and burns at a constant rate of 1.1 inches per hour. Let t represent the never of hours that have elapse

Alex17521 [72]

Answer:

(a) Number of inches that have burned from the candle since it was lit is (1.1t) inches

(b) The remaining length of the candle is (16 - 1.1t) inches

Step-by-step explanation:

(a). Length of candle before it was lit = 16 inches

Constant rate at which at which candle burns = 1.1 inches per hour

Let t represent the number of hours that have elapsed since the candle was lit

In 1 hour, 1.1 inches of the candle burned

Therefore, in t hours, (1.1t) inches of the candle would have burned since the candle was lit

(b) Remaining length of candle = length of candle before it was lit - length of candle that have burned = 16 inches - 1.1t inches = (16 - 1.1t) inches

If the area of the rectangle to be drawn is 42 square units, where should points B and D be located if they lie to the right of

klio [65]

We know a square is four equal sides. Saying this there are seven squares between A and C so, with the knowns of four equal sides and seven square between A and C you can divide 42/7=6. With this information count six squares to the right from A and the same for C with a result of

B(2,4), and D(2,-3) per graph.

Use substitution to solve the system. 5X+3Y=22 Y=2X-11

Ad libitum [116K]

Answer:

See below:

Step-by-step explanation:

Hello! My name is Galaxy and I will be helping you today. I hope you are having a nice day.

We can solve this problem in two steps, Comprehending, and Solving/Checking our answers. I'll be starting off with Comprehending.

Comprehending

We can solve the problem with substitution by finding out what one variable is equal to in terms of the second variable.

This is what we would call System of Equations where we need to find the point where the lines hit.

We can do this either with Graphing, or Algebra. In this case, we need to use substitution, so it has to be Algebraically.

Now that we know how to solve it/what to do, we can start solving.

Solving

We can solve the problem by first replacing y with its correct value in terms of x. Since we know the two equations, we can begin solving.

$y=2x-11\\5x+3y=22$

We can solve it by inserting our y value into the y value of the second equation.

$5x+3(2x-11)=22\\5x+6x-33=22\\11x=22+33\\11x=55\\x=5$

Now that we know our x value, we can solve for y by inserting it into an equation.

$y=2(5)-11\\y=10-11\\y=-1$

Now that we have solved, we have gotten out point of (5,-1)

We can test this by inputting it into an equation. (Any of the latter).

$5(5)+3(-1)=22?\\25-3=22?\\22=22$

Now that we have checked our answer and it appears correct, we have gotten our answer of (5,-1).
