Answer:
Step-by-step explanation:
2 5/8+9 6/7 = 2+9+5/8 + 6/7 = 11 +5/8+6/7
Answer:
C
Step-by-step explanation:
using the pythagorean theorem,
a²+b²=c²
8²+7²=c²
64+49=c²
113=c²
10.63=c
Divide the whole numbers:
2.04 / -2 = -1.02
When Dividing scientific notation, subtract the exponents from each other:
-9 - -5 = -9 +5 = -4
The answer becomes -1.02 x 10^-4
Answer:
2 batches
Step-by-step explanation:
2/5 divide by 1/5
=2/5 * 5/1
=2 batches
Answer:
a.) w = 103 * 1.08^t
b.) 3.5weeks
Step-by-step explanation:
If Her current weight is 103 pounds and she hopes to multiply her her weight each week by 1.08, then
her weight after 1 week = 103 * 1.08 = 103 * 1.08¹
Her weight after 2 weeks = [weight of week 1] * 1.08 = [103* 1.08] * 1.08 = 103 * 1.08²
Weight after 3 weeks= [weight of week 2] * 1.08 = [103 * 1.08 * 1.08] * 1.08 = 103 * 1.08³
Hence weight (W) after t weeks = 103 * 1.08^t
b.) If W = 135, Then
103 * 1.08^t = 135
1.08^t = 135/103
1.08^t = 1.31
Taking log of both sides,
log 1.08^t = log 1.31
t log 1.08 = log 1.32
t = log 1.32/log 1.08
t = 3.5 weeks.
Hence, it will take her 3½ weeks to get to 135pounds weight.
