Answer: 10:9
Step-by-step explanation:
brother 1- 1m 60cm
brother 2- 1m 44cm
_________________________________________________________
the ratio would be brother 1 : brother 2 => 1m 60cm : 1m 44cm
_________________________________________________________
convert both the values to cm
1m = 100cm
brother 1 would be 100cm + 60cm or 160cm
brother 2 would be 100cm + 44cm or 144cm
_________________________________________________________
when simplified
the ratio of brother 1 to brother 2 would be 10:9
Answer: Simplifying
17.75x + 24 = 18.95x + 18
Reorder the terms:
24 + 17.75x = 18.95x + 18
Reorder the terms:
24 + 17.75x = 18 + 18.95x
Solving
24 + 17.75x = 18 + 18.95x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-18.95x' to each side of the equation.
24 + 17.75x + -18.95x = 18 + 18.95x + -18.95x
Combine like terms: 17.75x + -18.95x = -1.2x
24 + -1.2x = 18 + 18.95x + -18.95x
Combine like terms: 18.95x + -18.95x = 0.00
24 + -1.2x = 18 + 0.00
24 + -1.2x = 18
Add '-24' to each side of the equation.
24 + -24 + -1.2x = 18 + -24
Combine like terms: 24 + -24 = 0
0 + -1.2x = 18 + -24
-1.2x = 18 + -24
Combine like terms: 18 + -24 = -6
-1.2x = -6
Divide each side by '-1.2'.
x = 5
Simplifying
x = 5
Step-by-step explanation:
We know that the area of a circle has the formula A=πr²
We are given the diameter, and as we know that the diameter is twice the radius, we can divide the given diameter by 2.
27 ÷ 2= 13.5
Now, plug-in the number into the formula.
A=πr²
A=π×13.5²
A=π×182.25
(Assume π=3.14)
A=3.14 × 182.25
A=572.265
A=572.3 square meters.
Therefore, the area of the circle is 572.3 square meters.
25)divide by 3/8 on both sides
26) divide by 21 both sides
