Answer:
6
Step-by-step explanation:
you first divide 81 by 18 and get 4.5, that is the number of children per adult.
next you'll divide 27 by 4.5 and 6.
that's the answer.
R - 6m = n.....add 6m to both sides
r = n + 6m <==
20+20=40*.1 (10%) =4
40-4=36
Answer: 258023743333miles³
Step-by-step explanation:
Volume of a sphere = 4/3πr³.
where,
π = 3.14
r = radius = 3950
Volume of a sphere = 4/3πr³.
= 4/3 × 3.14 × 3950³
= 4/3 × 3.14 × 61629875000
= 258023743333miles³
The volume of our planet if we assume that it is a sphere with the radius 3,950miles will be 258023743333miles³
Answer:
Slope is 2/15.
Step-by-step explanation:
To find slope, equation should be written in y- intercept form.
y=mx + b, m is a slope.
(2/3)x -5y =10
5y = (2/3)x - 10
y=(2/15)x -2
Slope is 2/15.
