Answer:
8
Step-by-step explanation:
The correct anwser is 12. The solution is 76/6 then you know it's 12.666666666... But we can't say that's 13 because they are human. So wecan only say the number is 12 not 13.
5m-3h=45
/5 = /5
m-3h=9
-3 = -3
m+h=6
-m = -m
h=6-m
The numbers are "x" and "y", therefore, we suggest this system of equations:
x-y=14
xy=1800
We can solve by substitution method.
x=14+y
(14+y)y=1800
14y+y²=1800
y²+14y-1800=0
Now, we solve this square equation:
y=[-14⁺₋√(196+7200)] / 2=(-14⁺₋86)/2
We have two solutions:
y₁=(-14-86)/2=-50 ⇒x=14+y=14-50=-36
y₂=(-14+86)/2=36 ⇒x=14+y=14+36=50
Answer: we have two solutions:
Solution1: The first number is -36 and the other number is -50
Soltuion2: The first number is 50 and the other number is 36
Answer:
<h2>The volume is
</h2>
Step-by-step explanation:
We need to convert the radius and the height to cm first
1 cm = 0.393701 in
r (cm)= 3.7 in
1 cm = 0.393701 in
h (cm)= 5.6 in
The formula the volume of cylinder is
