Answer:
Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron.
Step-by-step explanation:
*Use the Pythagorean Theorem
a^2 + b^2 = c^2
6^2 + 5^2 - c^2
36 + 25 = c^2
61 = c^2 *Square root 61
c^2 (c squared) = about 7.8
Answer:
$148
Step-by-step explanation:
We are given the expression:
48+25h
We are also given h=4. Since we know what h is equal to, we can substitute 4 in for h.
48 + 25h (h=4)
48 + 25(4)
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition and Subtraction.
First, multiply 25 and 4.
48+ (25*4)
48+100
Next, add 48 and 100
48+100
148
The customer will have to pay $148
Basically the line (/) means divide so basically 1 divided by 400 but we need a percentage so 1/400 = 0.0025 which will be 0.25%
Hope this helps this is as much as I can really explain it.
Answer:
$66.8
Step-by-step explanation:
The formula for simple interest is |=prt.
P=Principal R=Rate T=Time
Now you plug the numbers in |=668*0.05*2
Multiply 668*0.05= 33.4
Then you multiply that by 2= 33.4*2=66.8
That is your answer.
