Answer:
y = 15x+32
Step-by-step explanation:
Given
y to be the total minutes Andrew will play video games today
x is the total number of games played after school
If he wants to play an additional 15 minutes each of x games after school today, the total minutes he will use for the x games will be 15* x = (15x)minutes
We are told that he has initially spent 32minutes on video games. hence;
Total minutes Andrew used on games y = (15*x)+32
The required equation will be y = 15x+32
Answer:
10-5
Step-by-step explanation:
As per the attached figure, right angled
has an inscribed circle whose center is
.
We have joined the incenter
to the vertices of the
.
Sides MD and DL are equal because we are given that 
Formula for <em>area</em> of a
As per the figure attached, we are given that side <em>a = 10.</em>
Using pythagoras theorem, we can easily calculate that side ML = 10
Points P,Q and R are at
on the sides ML, MD and DL respectively so IQ, IR and IP are heights of
MIL,
MID and
DIL.
Also,


So, radius of circle = 
Answer:
Volume of Cylinder=πr²h
22/7*2/1*2/1*5/1=
440/7=62.857 to nearest tenth
62.860, if u like u put the zero.
Answer:
v = 8
Step-by-step explanation:
8v+5=13+7v
Subtract 5 from 13
8v=8+7v
Subtract 7v from 8v
Final answer: v = 8
