Answer:
87
Step-by-step explanation:
Complementary angles add to 90 degrees
Let c be the complement
c + 3 = 90
Subtract 3 from each side
c+3-3 = 90-3
c = 87
Answer:
The diameter is 2
Step-by-step explanation:
You divide 6.28/3.14
Because pie is 3.14
So therefore the diameter is 2.
Since you are trying to isolate , you will need to remove the 13 through division:
Our answer is x = 6.
Answer:
x=40 and y= 60
Step-by-step explanation:
<u>step:1</u>
Let 'x' and 'y' are two numbers
given data the sum of two numbers is 100
x+y = 100......(1)
Given difference of two numbers are
x - y = -20 ......(2)
<u>Step :2</u>
solving the equation (1) and (2)
adding the equations (1) and (2)
x+y+x-y=100-20
cancelling 'y' terms are
2 x = 80
dividing "2" on both sides, we get
x = 40
<u>Step :3</u>
substitute x = 40 in equation (1)
x + y =100
40 + y = 100
subtracting "40" on both sides, we get
40 + y - 40 = 100 -40
y = 60
Final answer:-
The two numbers are x = 40 and y= 60
Answer:
20%
0.5
Step-by-step explanation:
There are 20 margins, so you have to count how many are 6.0 or higher. There are 4 margins that fit this so you divide the 4 margins by 20, then multiply the quotient by 100. That's how you get 20%.
