Answer:
100 - 2 = 98
$45 = 98
divide both sides by 98 to find the amount of 1%
45/98 =1%
0.45918367 = 1%
now multiply by 100 to find original price
0.45918367 X 100 = 45.92
100% = 45.92
Answer:
8%
Step-by-step explanation:
let,
this year population of students (pt)= 195
last year population of students (p)= 210
time(t)= 1 year
Population Change( R)= ?
we have,
pt= p( 1 - R/100)^t
195 = 210 ( 1 - R/100)^1
0.92= 1 - R/100
0.92-1= R/100
- 0.08 = - R/100
R= 0.08×100
R= 8%
Answer:
30
Step-by-step explanation:
Given the equation;
n/10 + 7 = 10
We are to find the value of n
Subtract 7 from both sides
n/10 + 7 - 7 = 10 - 7
n/10 = 3
Cross multiply
n = 10 * 3
n = 30
<em>Hence the solution to the equation is 30</em>

Step-by-step explanation:
Answer:
m∠BJK = 146
m∠IJB = 26
Step-by-step explanation:
m∠BJK + m∠IJB = m∠IJK
<em>146 </em>+2x + 2x +<em>26</em> = 172
<em> 172 </em> + 4x = 172
4x = 172 -172 = 0
x = 0
m∠BJK = 146
m∠IJB = 26
