Answer:
hope this helps A block of ice melts in 2.5 hours when the temperature is 54 degrees.
Step-by-step explanation:therefore you can increase 2.5 and decrease 54 to whatever number you need
To solve this, we need to follow <em>PEMDAS </em>(Order of Operations)
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
Following this order of math will get you your answer for any math problem.
First we'll do -4*1/3, which gets us -4/3. Then we'll add 5 to get

<em>:)</em>
(0.7)(0.4)=0.28 because 7×4 is 28 and you just add a 0
Answer:
5π m
Step-by-step explanation:
Using the pythagorean theorem we can figure out that the third side is 5m
A^2 + B^2 = C^2
3^2 + 4^2 = C^2
9 + 16 = C^2
25 = C^2
√23 = √(C^2)
C = 5m
Side C is also the diameter of the circle, so the radius is 5/2, or 2.5
From that we can use the circumference formula, Circumference = 2π<em>r</em>
Circumference = 2 π (2.5) = <u>5π m</u>
