Answer: 90
Step-by-step explanation:
In the number 73,951, the digit 9 is on the third position, so you need to put the number of the position minus one zeros before it: ( position number 3, 3 - 1 = 2, so we put 2 zeros)
the 9 in that digit represents a 900.
now, 1/10 times that number is:
900*(1/10) = 900/10 = 90
then the answer is 90.
In the number 90, the value represented by the 9 is equal to 1./10 times the value represented by the 9 in 73,951
Answer:
a. what is the perimeter of a square with side length:
3 cm=12cm
7 cm=28
b.90
Because there are 4 inside angles the sum of the four angles must equal 360 degrees.
Add the angles to equal 360:
4x + 3x + 2x + 3x = 360
Simplify:
12x = 360
Solve for x by dividing both sides by 12:
x = 360 /12
x = 30
Now you have x, solve for each angle:
ABC = 4x = 4 x 30 = 120 degrees.
BCD = 3x = 3 x 30 = 90 degrees.
CDA = 2x = 2x 30 = 60 degrees.
DAB = 3x = 3 x 30 = 90 degrees.
C. It's important to know that a four sides figure needs the inside angles when added together need to equal 360 degrees.
y= (1, 4) times x + (15, 4)
It would be 4.5. Hope this helps!
