Answer:
b=-10
c=25
Step-by-step explanation:
if the only solution is 5 so
x^2+bx+c=(x-5)²=x²-10x+25
b=-10
c=25
Answer:
<u>d = 2r or d = C/π</u>
Diameter is equal to two times the radius or Circumference/π
<u>C = 2πr</u>
Circumference is equal to two times π multiplied the radius
<u>A = π * r²</u>
The area of the circle equals to π multiplied by the radius squared
Step-by-step explanation:
Let's find the formulas for d, C and A
d = diameter
C = Circumference
A = Area
r = radius
π ≅ 3.1416
d = 2r or d = C/π
Diameter is equal to two times the radius or Circumference/π
C = 2πr
Circumference is equal to two times π multiplied the radius
A = π * r²
The area of the circle equals to π multiplied by the radius squared
Answer:
A) 184.5 B)22.5
Step-by-step explanation:
207/2= 103.5
A is heavierand the diference of their weights is 81 tons A is 103.5 plus 81 tons or 184.5
And B is 103.5 minus 81 tons or 22.5 tons
34.06 is the the correct way of saying it.
Hey there!
Question #1.
36% of 400
= 36% * 400
= 36/100 * 400/1
= 36 ÷ 2 / 100 ÷ 2 * 400/1
= 18/50 * 400/1
= 18 ÷ 2 / 50 ÷ 2 * 400/1
= 9 / 25 * 400/1
= 9(400) / 25(1)
= 3,600 / 25
= 3,600 ÷ 25
= 144
Therefore, the answer should be: 144
Question #2.
16% of 32
= 16% * 32
= 16/100 * 32/1
= 16 ÷ 2 / 100 ÷ 2 * 32/1
= 8 / 50 * 32/1
= 8 ÷ 2 / 50 ÷ 2 * 32/1
= 4 / 25 * 32/1
= 4(32) / 25(1)
= 128 / 25
≈ 5.12
≈ 5 3/25
Therefore, the answer should be:
• 128/25
• 5.12
• 5 3/25
(Either of those should work because they are equivalent or equal to each other!)
Good luck on your assignment & enjoy your day!
