Answer:

x = 405

Step-by-step explanation:

DBE is 0.1x-33 and the measurement of angle CBE is

The sum of both angles form a right angled triangle ;

DBE + CBE = DBC

DBC = RIGHT angled triangle = 90°

(0.1x-33) + (0.3x - 39) = 90°

0.1x - 33 + 0.3x - 39 = 90°

0.1x + 0.3x - 33 - 39 = 90

0.4x - 72 = 90

0.4x = 90 + 72

0.4x = 162

x = 162 / 0.4

x = 405

2.4m log is cut into lengths into the ratio 7 : 5. Find the longer length in cm.
sergeinik [125]

Answer:

140 centimeters.

Step-by-step explanation:

Hello!

A 2.4 meter log is split into the ratio 7:5. Each unit part is one x-increment, so the log is split into 7 x-increments and 5 x-increments.

Find the longer length:

  • 2.4 into 7:5
  • 2.4 = 7x + 5x
  • 2.4 = 12x
  • x = 2.4/12
  • x = 0.2

Now, we must find the longer length, 7x.

  • 7x
  • 7(0.2)
  • 1.4

The longer length is 1.4 meters, but we want it in cm.

There are 100 centimeters in a meter.

  • 1.4 meters = 1.4 * 100
  • 1.4 meters = 140 centimeters

The longer length is 140 centimeters.

What is 8,792 as a fraction?
Wittaler [7]

We have a number 8.792.

To write it as a fraction first count the number of decimals and call it n (which, in our case, has a value of 3). Multiply the number with 10^n to get 8792. Then divide this number by 10^n to get \frac{8792}{10^n} from here you can either simplify (if the assignment says so, then the simplified fraction is \frac{1099}{125}) or not.

Hope this helps.
