Ok, so oriiginal+tax
if tax is in %, remember that x%=x/100
example, first one
1. tax is 5%, so we find 5% of 1.95 which is 0.05 times 1.95 which is .0975 or about 10 cents so total is 1.95
but wait, we found a shortcut
1(1.95)+0.05(1.95)=original+tax
we can undistribute the 1.95
1.95(1+0.05)=original+tax
so therfor we conclude that
oriignalprice(1+taxindecimal)=sale price
neato
1. sale price=1.95(1.05)=$2.0475 or about $2.05
2. sale price=58.50(1.01)=$61.425 or about $61.43
3. sale price=49.45(1.02)=$50.439 or about $50.44
4. sale price=58.50(1.01)=$61.425 or about $61.43
5. sale price=2500.00(1.01)=$2525.005.
6. sale price=50.00(1.02)=$51.00
7. sale price=149.50(1.02)=$152.49
8. sale price=2800.00(1.01)=$2828.00
9. sale price=2000.00(1.06)=$2120.00
10. sale price=9.50(1.06)=$10.07
11. sale price=4.95(1.05)=$5.1975 or about $5.20
12. sale price=50.00(1.06)=$53.00
13. sale price=299.95(1.06)=$317.947 or about $317.95
Answer:
The answer is about 2827.4 in cubed.
Step-by-step explanation:
The formula for the volume of a cylinder is
V = π·r²·h
Filling in the given information, your cylinder's volume is
V = π·(10 in)²·(9 in)
V = 900π in³
V ≈ 2827.4 in³

I'm not sure if this question was correctly transcribed but is it suppose to read find if x=15, find y = 6x+30 ?
If so then y = 120
The way it is written now, If x = 15 then 6x cannot equal 30 which is why I asked. Sorry if I'm not understanding the question.
Answer:
m<PSR = 60°
Step-by-step explanation:
Given:
m<OPQ = 50°
m<ORQ = 70°
Required:
m<PSR
Solution:
m<PQR + m<OPQ + m<ORQ = 180° (Sum of triangle)
m<PQR + 50 + 70 = 180 (Substitution)
m<PQR + 120 = 180
m<PQR = 180 - 120
m<PQR = 60°
One of the properties of a kite states that the angles where the unequal sides meets are congruent to each other. Therefore:
m<PSR = m<PQR
m<PSR = 60° (substitution)
