an elevator starts at the 6th floor it goes up 7/4 plus and then it goes down 10 floors. a second elevator starts on the 20th floor. it goes down five floors three times, and then it goes up 12 floors. which elevator ends up on a higher floor?​

Answers

Answer 1

Answer:

Elevator 2

Step-by-step explanation:

Well let's make this simply by focusing on elevator number 1

it is on the 6th floor so we represent that as

6

Now it goes up 7/4 which is also the same as 1 3/4

the equation looks like this:

6+1 3/4

Add them together:

7 3/4

Now it goes down 10 meaning it is -10 add that to the equation:

7 3/4 - 10

Which is -2 1/4

Elevator number 1 is at floor number -2 1/4

Now for Elevator number 2

It is on the 20th floor which will make the equation looks like this:

20

Now it goes down five floors three times which can be represented like this:

20-5(3)

Simplify (Multiplication goes first according to the Order of Operations)

20-15= 5

Now it is 5 but it goes up 12 floors so the equation looks like this:

5+12

Simplify:

17

Now you could tell that elevator 2 ends up on a higher floor

Hope this helps!

What is the solution to 34x+85=3(13x+7)

Answers

Answer:

x=12.8

Step-by-step explanation:

34x+85=39x+21

34x-39x=21-85

-5x = -64

x = -64/-5

x = 12.8

Answer:

x = 34/5

Step-by-step explanation:

Just solve the equation

[tex]34x + 85 = 3(13x + 17)\\34x + 85 = 39x + 51\\85 - 51 = 39x - 34x\\34 = 5x\\x = 34/5[/tex]

Time is always independent. Time depends on nothing, no matter what other quantity is changing time will continue to move, and it will always move in the same way (seconds, minutes, hours, and so on never change their duration).

The dependent quantity would be temperature. How hot the tea is depends on how much time has passed.

Last year, Summerfield Steel sold 6.5×104 pounds of steel to private businesses and 2.5×105 pounds of steel to government agencies. This year, they expect to sell 3 times that amount. How much steel would that be?

Answers

Answer:

9.45 × 10⁵ pounds of steel

Step-by-step explanation:

Last year, Summerfield Steel sold 6.5×10⁴ pounds of steel to private businesses and 2.5×10⁵ pounds of steel to government agencies.

Total amount of steel sold last year = (6.5 × 10⁴ + 2.5 × 10⁵) pounds = 315000 pounds = 3.15 × 10⁵ pounds

This year, they expect to sell 3 times that amount.

This year = 3 × 3.15 × 10⁵ pounds

= 9.45 × 10⁵ pounds of steel

A snowbank that is 6 inches deep is melting at a rate of 0.5 inch per hour. Write a linear function to model the scenario and identify the domain and range of the function.

Answers

Answer:

y = -0.5x + 6, Domain [0,12] and Range [0, 6]

Step-by-step explanation:

The slope in a linear function represents the rate of change. Since the amount of snow is decreasing (indicating a negative slope) at 0.5 inches an hour, our slope would be -0.5.

Our y intercept, 6, would be the starting amount of snow. At 0 hours, no snow has been melted.

Our domain is [0,12] these are the x values from where at zero there is 6 inches of snow and at 12 there is 0 inches of snow.

Finally, our range is [0,6]. Since there cannot be no more than 6 or less than 0 inches of snow, our range is [0,6]

If 4(r + 2) – 13 = 11, what is the value of r?

Answers

Answer:

r = 4

Step by step explanation :

Step 1 : Add 13 to both sides.

4(r + 2) - 13 + 13 = 11 + 13

4(r + 2) = 24

Step 2 : Divide by 4 on both sides.

[tex]\frac{4(r+2)}{4} = \frac{24}{4}[/tex]

r + 2 = 6

Step 3 : Subtract 2 from both sides.

r = 4

The value of r is 4 in the given expression and this can be determined by using the arithmetic operation.

Given :

Expression -  4(r + 2) – 13 = 11

The following steps can be used to evaluate the given expression:

Step 1 - Write the expression.

4(r + 2) – 13 = 11

Step 2 - Add 13 on both sides in the above equation.

4(r + 2) – 13 + 13 = 11 + 13

4(r + 2)  = 24

Step 3 - Multiply 4 by (r + 2) in the above expression.

4r + 8 = 24

Step 4 - Subtract 8 on both sides in the above expression.

4r + 8 - 8 = 24 - 8

4r = 16

Step 5 - Divide 4 on both sides in the above equation.

r = 4

The value of r is 4.
