Help With This Equation:

Mathematics
1 answer:
kompoz [17]3 years ago
5 0

Answer:

  • Base = 3 units
  • Height = 7 units
  • Area = 3 · 7
  •   = 21 units²

Step-by-step explanation:

Count the squares. The horizontal extent is 3 squares, so is 3 units.

The vertical extent is 7 squares, so is 7 units. We're only concerned with the vertical distance between the horizontal lines at the top and bottom of the figure. The slant distance along the side of the figure is irrelevant.

From there, fill the numbers into the blanks and do the multiplication. "bh" means multiply the Base value by the Height value.

_____

<em>Comment on units</em>

It is not quite true that 3·7 = 21 units². What is true is that ...

  (3 units)·(7 units) = 21 units²

The equal sign should be treated with respect and care. What is found on one side must always be strictly equal to what is found on the other side. You cannot simply add "units²" to one side of the equation because you feel like it. There must be something corresponding on the other side of the equation.

You can actually multiply and divide units (and in Physics, you're expected to do so). The units can be attached to the numbers and treated in the math as though they were a variable. This can be especially helpful in area, volume, time/speed/distance, and unit-rate problems.

Tim installs 50 square feet on his floor in 45 minutes. At this rate, how long does it take him to install 495 square feet?
Katena32 [7]

Answer:

445.5 minutes

or 7 hours 25 minutes 30 seconds

Step-by-step explanation:

We can use ratio's to solve

50 ft^2           495 ft^2

--------------  = ------------

45 minutes    x minutes

Using cross products

50x = 45*495

50x=22275

Divide each side by 50

50x/50 = 22275/50

x =445.5

445.5 minutes

If we want to convert to hours and minutes, divide by 60

7 hours is 420 minutes

445.5 -420 = 25.5

7 hours 25 minutes

.5 minutes is 30 seconds

7 hours 25 minutes 30 seconds
