b) 30-100
C) 30 + (-100)
d) Both b and c
Answer:
B
Step-by-step explanation:
Mr.Riley was 30 feet above the water, which means he is at +30 above sea level. If he descends 100 feet, that means he goes 100 feet lower then that. 30 - 100 is equal to -70. He is 70 feet under water after he dived. You do not need to know the answer, but it helps to visualize the problem you have, therefore, finding the answer
B) $10.00
C) $25.20
D) $5.20
A $3.478
B. $3.792
C. $2,489
D. $2,256
Answer:
A
Step-by-step explanation:
Becuase he wanted more then 3000
Answer:
13.48
Step-by-step explanation:
So I used the Order of Operation and went in order to solve the problem. First is P (Parentheses)
(1.74) = 1.74
Next, Exponents (E).
There are none.
Then, Multiplication and Division (from left to right).
2(1.74) = 3.48 | 15-9+2.65+1.35+3.48.
The fourth is Addition and Subtraction (from left to right).
15-9+2.65+1.35+2= 13.48
Answer:
Samantha payed 12.71$ for her purchase.
Step-by-step explanation:
I may have misunderstood the question, but it looks like you can use a calculator for this!
6.19 + 2.85 + 2.29 + 1.38 =
12.71
x = 0.973
3e^(2x) +5 = 26
3e^(2x) = 21 . . . . . subtract 5
e^(2x) = 7 . . . . . . . divide by 3
2x = ln(7) . . . . . . . .take the natural log
x = ln(7)/2 ≈ 0.973 . . . . divide by 2 and evaluate
Answer:
x= .973
Step-by-step explanation:
3e^2x +5=26
Subtract 5 from each side
3e^2x +5-5=26-5
3e^2x =21
Divide by 3 on each side
3/3e^2x =21/3
e^2x =7
Take the natural log on both sides
ln (e^2x) =ln (7)
2x = ln (7)
Divide by 2
2x/2 = ln(7)/2
x = ln(7)/2
x is approximately .972955075
Rounding to the nearest thousandth
x = .973
