The plant grow 3.6 centimeter in 18 days and the student written it  incorrectly as 1.44 days.

Division:

Division is the process of breaking a number up into equal parts, and finding out how many equal parts can be made. It is a reverse process of multiplication.

Given:

The ratio of growth for a plant is 0.2 centimeters per 0.5 day.

A student found the number of days for the plant to grow 3.6 centimeters to be 1.44 days.

Here we have to verify if the student is found the correct value or not.

For one day the plant grow 0.2 centimeter.

So, for 3.6 centimeter it will take

=> 3.6 / 0.2

=> 18

So, for 3.6 centimeter it will take 18 days.

So, here the student written it incorrectly as 1.44 days.

The measures of two supplementary angles have a ratio of 2:4. What is the measure of the smaller angle
Rom4ik [11]
Simplify 2:4
you get 1:2

this means the larger is two times the smaller.

well, we have to use a system of equations.

we know two supplementary angles add up to be 180°.we can create our first equaition, using 

smaller angle + larger angle = 180
s + l = 180

we can create our second equation using 
two times the smaller = larger
2s = l

our two equations are:
2s = l
s + l = 180

now that we have  the two equations, we can solve using subsitution to isolate the variable.
s + l = 180
s + (2s) = 180

simpify.

3s = 180
s = 60

the smaller angle has a value of 60.
now, remember that the larger angle is two times the smaller.

60 x 2 = 120

smaller angle: 60
larger angle: 120

we know this is correct because we know the smaller is 1/2 or 1:2 or 2:4 times the bigger, and the two angles add up to be 180 (60 + 120)

hope this helps and have a great day!

Point A is inside triangle E D F. Lines are drawn from the points of the triangle to point A. Lines are drawn from point A to th
Crazy boy [7]

Answer:

Option B. 3 is the answer.

Step-by-step explanation:

To draw a circumcenter of a triangle we draw the perpendicular bisectors of the the sides of the triangle first.

Intersection point of these perpendiculars drawn is the circumcenter of the circle.

Distances of the circumcenter to the vertices are same, that means distance of circumcenter from the vertex is the radius of the circle.

Therefore, length of AE and AD will be same in measure.

AE = AD

2n + 4 = 10

2n = 10 - 4

2n = 6

n = 3

Therefore, Option B. 3 is the answer.
