What is 1023x102+112-5=
kiruha [24]

Answer:

The answer is 104,453.

Step-by-step explanation:

Multiply 1,023 and 102 first because you always have to do your problems left to right in math. Your equation should now look like 104,346 + 112 - 5. Calculate the sum of the positive numbers by adding 104, 346 + 112. Your equation should now be 104,458 - 5. Then lastly, you subtract the numbers 104,458 and 5, and you should get 104, 453 as your answer.

A triangular section of land is fenced off due to contamination. Two sides of the triangle are each 16 meters ( 16m) longer than
Sphinxa [80]

Answer: the shortest side is 30m

Step-by-step explanation:

Let the shortest side be a meters

If side 2 is 16m longer than the shortest side, then it is (16+a)meters.

The same goes with side 3.

Then,

a + (16+a) + (16+a) = 122m

32 + 3a = 122m

Collecting like terms together,

3a = 122 - 32

3a = 90

Divide by coefficient of a

3a/3 = 90/3

a = 30 meters

Check:

30 + (16+30) + (16+30)

30 + 46 + 46 = 112

asambeis [7]

9514 1404 393

Answer:

  70 square units

Step-by-step explanation:

The overall outline is 15 units wide and 8 units high, for an area of ...

  A = WH

  A = (15 units)(8 units) = 120 units²

__

The white space taken out of that overall area is 5 units high and 15-4-1 = 10 units wide. The area of the white space is ...

  A = (5 units)(10 units) = 50 units²

__

The shaded area is the difference between the overall area and the white space taken out:

  shaded = 120 units² -50 units² = 70 units²
