Width = w=?
Length = l=(3w+8)cm
Perimeter = p = 128cm
Perimeter of a Rectangle = length + length + width + width
Perimeter of a Rectangle =2 length +2 width
P = 2l +2 w
128=2(3w+8)+2w
128=6w+16+2w
128-16=8w
112=8w
112/8=8w/8
14=w
w=14
Width = w= 14cm
Length = l=(3w+8)=3(14)+8 = 42+8 = 50cm
The fraction 3/5 is greater then 1/2
Answer:
A's radius is half so multiply it by 2 to get the diameter which is the same as B's.
Step-by-step explanation:
Answer: x=5/3
Step-by-step explanation:
For this problem, we can use teh information given to write out an equation and solve. Let's use x for the unknown number.
5x+5=2x+10
The left side of the equation comes from the part that says "five times a number plus 5". That is modeled above. The right side of the equation comes from "has the same value as twice the number plus 10".
5x+5=2x+10 [subtract both sides by 2x]
3x+5=10 [subtract both sides by 5]
3x=5 [divide both sides by 3]
x=5/3
Now, we have found the unknown number, x=5/3.
Answer:
e. 5.0329 g/mL
Step-by-step explanation:
Density is defined as mass divided by volume of an object. The volume displaced is:
#Density is then calculated as:
#Correct significant figures should correspond to the highest given in the question.
Hence the density of the metal is 5.0329g/mL
