84 Percentage increase
Step-by-step explanation:
Detailed calculations & verification
Introduction. Percent, p%
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
40% = 40/100 = 40 ÷ 100 = 0.4.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 40% of its value.
Percentage increase = 40% × 210
New value = 210 + Percentage increase
Calculate the New Value
New value =
210 + Percentage increase =
210 + (40% × 210) =
210 + 40% × 210 =
(1 + 40%) × 210 =
(100% + 40%) × 210 =
140% × 210 =
140 ÷ 100 × 210 =
140 × 210 ÷ 100 =
29,400 ÷ 100 =
294
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 210 =
294 - 210 =
84
Answer:
n = 40
Step-by-step explanation:
n - 12 = 28
add 12 to both sides to remove the negative 12
n = 28 + 12
n = 40
Answer:
x = 17.2
Step-by-step explanation:
cos 35 = x/21
0.8192(21) = x
x = 17.2
For this case we have the following relationship:
P1V1 = P2V2
Clearing volume 2 we have:
V2 = (P1 / P2) * (V1)
Substituting values we have:
V2 = (5.1 / 1.0) * (350)
V2 = 1785 mL
Answer:
this gas would occupy 1785 mL at 1.0atm
answer this fully! i need to know what x equals
X equal minus 0.5
