Answer:
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Step-by-step explanation:
Given that the car is traveling at a steady speed.
Distance traveled in 2 1/3 or 7/3 or (2.33) minutes = 1 3/4 miles
= 7/4 or 1.75 miles
Thus,
distance in 1 minute: 1.75/2.33 = 0.75 miles per minute
Thus,
- Distance in 47 minutes = 0.75 × 47 = 35.25 miles
- Distance in 1 hour or (60 minutes) = 0.75 × 60 = 45 miles
Answer:
Yes
Step-by-step explanation:
What is the problem?
3.2-5.7=-2.5 so its have to be a negative because a smaller number subtract a bigger number have to be equal to a negative number.
To find the future value the formula is
A=p e^rt
A future value?
P present value 8906.54
R interest rate 0.06
T time 9 years
E constant
A=8,906.54×e^(0.06×9)
A=15,283.68
To find the interest earned the formula is
I=A-p
I=15,283.68−8,906.54
I=6,377.14
Answer:
{10,8}
Step-by-step explanation:
-3x + 4y = -62
4x + 5y = 0
let's eliminate the x
-3x + 4y = -62 | x -4 |
4x + 5y = 0 | x 3 |
12x - 16y = 248
12x + 15y = 0
-------------------- -
-31y = 248
y = 248/(-31) = 8
since you must do this proble with elimination, we cant use subtitution. so we repeat the way once more to find x (eliminate y)
-3x + 4y = -62 | x 5 |
4x + 5y = 0 | x 4 |
-15x + 20y = -310
16x + 20y = 0
-------------------- -
-31x = -310
x = -310/-31 = 10
