Assuming the number is 331/2, or 331 over 2:
331/2 = 165.5 ÷ 400 = .4138 x 100% = 41.38%
100% - 41.38% = 58.62% not nickels
If the number is 33 1/2, or 33 and one half
33 1/2 = 67.5 ÷ 400 = 0.0838 x 100% = 8.38%
100% - 8.38% = 91.62% not nickels
Answer:
28.5 weeks
Step-by-step explanation:
First, subtract 3 from 60:
60 - 3
= 57
Then, divide this by 2:
57/2
= 28.5
So, the plant will be 60 in tall after 28.5 weeks
The surface area of a shape is basically the sum of all the areas on a shape.
We’ve been given that the side is 17 mm.
An area of a square is A=s^2, in which s means side. So we do 17^2 to get the area of ONE of the squares.
Once we do that we get that the area of 1 square is 289.
Since there are 6 squares we need to multiply 289 by 6.
Therefore,
SA=1734mm^2
Answer: A. (3,-2)
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable x
[2] 4x = 5y + 22
[2] x = 5y/4 + 11/2
// Plug this in for variable x in equation [1]
[1] 2•(5y/4+11/2) + 5y = -4
[1] 15y/2 = -15
[1] 15y = -30
// Solve equation [1] for the variable y
[1] 15y = - 30
[1] y = - 2
// By now we know this much :
x = 5y/4+11/2
y = -2
// Use the y value to solve for x
x = (5/4)(-2)+11/2 = 3
Solution :
{x,y} = {3,-2}
Answer:
a(n) = a+(n-1)d
a(n) = nth term of sequence
a = first term of sequence
d = difference between number
Step-by-step explanation:
a(5) = 9+(5-1)(-8)
a(5)= -23
