Answer:
Peter is 20 now
Step-by-step explanation:
Now
P = A +5 and J = 2P
plug in P in J = 2P = 2(A+5) =2A +10
In 5 years
J+5 = 3A
2A+10+5 = 3A
2A + 15 = 3A subtract 2A from each side
A = 15 so Alice is 15 now
P = A+5 =15+5= 20 so Peter is 20 now
Let's check :
P=20 J=40 A=15
in 5 years J = 45 A =3*15=45
Answer:
0.318 Pa
Step-by-step explanation:
Area of a circle= πr²
Area= π x 10²
Area= 314 m²
Pressure = force/area
Pressure = 100/314
Pressure = 0.318 Pa
P.S. You can substitute Pascals for N/m²
Hope this helps!
Answer:
1/3
Step-by-step explanation:
Considering the triangles are similar the side lengths would be proportional too
like AB is similar to DE so 5/15 = 1/3
Answer:
set of numbers
Step-by-step explanation:
It would be 3.5 as you start with 56 then take away 16 =40 then another witch is 24 the another 16 Is 8 so you have taken e16 away so far that's 3 pound and because you can take a full 16 off that makes it a half so final awnser is 3.5 56-16=40-16=24-16=8=3 pounds and a half hope I have helped you in any way
