Step-by-step explanation:
(a) So in order to find acceleration you would have to transpose the formula given so that acceleration is the subject of the equation;
F=ma
Because mass is multiplying acceleration to transpose this so that "a" is the subject you would do the opposite of Multiplication on the other side;
F=ma
a/f=m
a=fm
This now has "a" as the subject.
(b) This is the formula we will be working with ( a=fm) because this problem requires "a" to be the subject of the equation.
a=fm
a= -25 units × 5 units
a= -125 units
(c)The same rule applies mass is suppose to be the subject of the equation .
F=ma
m/f=a
m=fa
m = 25 units × 2.5 units
m = 62.5 units
X + 65 = 120
-65 -65
x = 55
Answer:
about 30.1 astronomical units or 4.5 billion kilometers.
Answer:
After 140 days
Step-by-step explanation:
The next time both plants will be watered together is simply the LCM of 10 and 14.
10 has multiples: 10, 20, 30, 40 , 50 ....
14 has multiples: 14, 28, 42, 56 ....
When will they next be equal?? That's the LCM.
We first do prime factorization of the numbers and then multiply each factor the greatest number of times it occurs in either number.
<u>Prime Factorization</u>
10 = 2 * 5
14 = 2 * 7
So,
LCM = 2^2 * 5 * 7 = 140
After 140 days
Answer:
40 Operators
Step-by-step explanation:
if 10 operators worked on 120 pages for 2 hours
P operators will work on the same pages for 30min
note: 2hrs= 120min
10×120min/120= P × 30/120
- cross multiply
- make P subject of the formula
P= 10×120×120/120×30
P = 40 operators
