Answer:
The surface are of a spehere with a radius of 13 is = to 5
Step-by-step explanation:
Step-by-step explanation:
2.
the volume of the box is
length × width × height = 13×13×13 = 13³ = 2197 cm³
the ratio of the density indignation tells us that every cm³ of soil weighs 1.33 g (or every unit of 1.33g soil fits into 1 cm³).
we have 2197 cm³.
their weight is
2197 × 1.33 = 2,922.01 g
so, the filled box clearly exceeds the max. weight of the window ledge, and it is NOT safe to put it there.
b
yes, it would be a little bit less dense.
because every bit of weight you put on top of something increases the pressure on and therefore the density of that something.
Answer:
(a+2)(b+2) = 4
Step-by-step explanation:
We are given the following quadratic equation:

Let a a and b be the solution of the given quadratic equation.
Solving the equation:

We have to find the value of (a+2)(b+2).
Putting the values:

Answer:
Step-by-step explanation:
take angle C as reference angle
using cos rule
cos C=adjacent/hypotenuse
cos C=21/75
cos C=0.28
C=
0.28
C=73.7 degree
