Answer:
1/10 of the days in September had rainfall more than 2 cm
Step-by-step explanation:
Use the information given:
- 2/5 of the days in September had rain
- 1/4 of the days in September that had rain, had more then 2cm of rain
- 1/4 of 2/5 is 2/20=1/10
The incenter of a triangle is where the angle bisectors of the triangle meet. That means angle A is 64, angle B is 74, and using the triangle angle sum, angle C is 42 degrees. Divide that in half to get the measure of DCA, 21 degrees.
The total units of stationery he has would be 55 approximately.
<h3>What is a system of equations?</h3>
A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
David keeps a range of stationery in his study.
Let the pencil is represented by x.
Let the erasers be represented by y.
Let the pens be represented by z.
Let n be the stationery.
5/7 of his stationery consists of pencils.
x = 5/7 n
1/6 of the remaining stationery consists of erasers.
y = 1/6 n
There are 20 pens in his study.
z = 20
The total stationery
X + y + z
5/7 n + 1/6 n + 20 = n
20 = n -23/ 36 n
20 = 13 / 36 n
n = 55.38
Therefore, the total units of stationery he has would be 55 approximately.

Table B represents a proportional relationship
Okay so first we will add
55+ 20= 75
then subtract 75-60 = 15
then add 17+1= 18
the answer is 19:15
