Answer:
5
+40
Step-by-step explanation:
perimeter of circle=2
r
so 5 is r(radius)
so 10
, but since it’s semicircle, you have to divide by 2, so
5
perimeter of rectangle=15+10+15 because you don’t count the inside, so that equals 40
so 5
+40
Answer:
line
Step-by-step explanation:
y= 2+(x-1)*1= x+1
y=x+1
linear function, the graph is going to be a line
P% = p/100
20% = 20/100 = 2/10 = 0.2
20% of 70 plants:
"0.2 x 70 plants = 14 plants"
Answer:
Step-by-step explanation:
we have that
The scale drawing is

we know that
Using proportion find out the actual dimensions of the volleyball court
Let
x -----> drawing court lengths in cm
y ----> court lengths in cm
For x=40 cm

For x=80 cm

Find the equation for the proportional relation ship between drawing court lengths x in centimeters and court lengths in y centimeters
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form
or
For x=40 cm, y=900
substitute
----->
The equation is
Answer:
132600
Step-by-step explanation:
I was always taught like this, and this should be the best estimate:
28 x 4417 --> 30 * 4420 --> 132600
Some other possible estimates with simpler values:
30 * 4400 --> 132000
30 * 4500 --> 135000
30 * 4000 --> 120000
