Answer:
3.v-4=6
v=6+4
v=10
6.y-32=-1
y=-1+32
y=31
9.-1=t+(-19)
-1=t-19
-1+19=t
18=t
12.u+(-5)=-15
u-5=-15
u=-15+5
u=-10
15.47=w-(-8)
47=w+8
47-8=w
39=w
21.18f=-216
f=-216/18
f=-12
24.96=-24a
96/-24=a
-4=a
27.-84=d/3
-84*3=d
-252=d
30.81=1/6*n
81=n/6
81*6=n
486=n
33.5/9*p=-10
5p=-10*9
p=-90/5
p=-18
12.699
Step-by-step explanation:
i think if you do 26-22.4, you get the leg of the small triangle which is 3.6
then do Pythagorean theorem
3.6^2 + x^2 = 13.2^2
12.96 +x^2 = 174.24
174.24-12.96
x^2 = 161.28
take square root
x = 12.699
Question 1
Volume of a cylinder = πr²h
r= radius h= height
diameter = 2*radius
diameter = 2* 4cm= 8cm
Volume = π × 4² × 11
= 553.14cm³
1/2 = 50%
