Answer 1
Answer: The circumference of a circle=2\pir
We know that diameter is double the radius, and therefore can be written as d=2r
Circumference of a circle in terms of diameter is C=\pid
The 2r cancels out

Weekly Question:In the rectangle below, the line MN cuts the rectangle into two regions. Find x the length of segment NB so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.

Answers

Answer:

(1/2)(10)(x + 15 + x) = (2/5)(10)(20 + x)

(1/2)(2x + 15) = (2/5)(x + 20)

5(2x + 15) = 4(x + 20)

10x + 75 = 4x + 80

6x = 5

x = 5/6

NB = 5/6
The answer for this question is really interest and that is N= to 5/6

A certain type of bamboo plant grows 1.2 feet in 1 day at that rate how many feet could the plant grow in 0.5 day

Answers

in .5 day, since .5 is half of one day , the bamboo will grow only .5× more so...
1.2÷5 = 0.6ft

The given bamboo can grow 0.6 feet in five days.

Ratio and Proportion

You can use the provided rate to calculate how many feet the bamboo plant could grow in 0.5 days. You can set up a proportion to determine the growth in 0.5 days if the plant grows 1.2 feet in one day.

So we can have 1.2 * 0.5 = x to represent the growth in 0.5 days.

x = 1.2 * 0.5

x = 6.0

As a result, at the specified rate, the bamboo plant might grow 0.6 feet in 0.5 days.
