Answer:
Young boy will grow to height 132 cm in 12 months.
Step-by-step explanation:
Given:
Growing rate = 3.5 cm per month
Current height = 90 cm
Let the number of months be x
Required height = 132 cm
We need to find the number of months required to grow the height till 132 cm.
Hence Number of months required can be calculate by subtracting Required height with Current height and then dividing it with growing rate.
Framing the above statement in equation form we get;
Hence Young boy will grow to height 132 cm in 12 months.
Answer:
NO solution, this statement is not true.
Step-by-step explanation:
Distribute
1.5x-12=3/2x-1.2
Combine Like terms
1.5x=3/2x+10.8
Combine like terms
0=10.8
NO solution! 0 is NOT equal to 10.8!
Answer:
length of chord is 6cm
Step-by-step explanation:
Here, we are to calculate the length of the chord.
It should be understood that the chord has a length of 0.8cm from the center of the circle of radius 3cm, thereby forming two right-angled triangles with the radius 3cm being the hypotenuse of each and 0.8cm being the height of each.
Now, the chord is divided into 2 by this height dropping from the center of the circle. To calculate the first half, we use Pythagoras’ theorem with 3cm being hypotenuse and 0.8cm being the other side.
mathematically;
3^2 = 0.8^2 + l^2
9 = 0.64 + l^2
l^2 = 9-0.64
l^2 = 8.36
l = √(8.36)
l = 2.89 approximately
The length of the chord would be 2l = 2 * 2.89 = 5.78 cm which is 6cm to the nearest length
