Answer:
See below.
Step-by-step explanation:
D(t) = 3260 - 55t
The function that shows their distance from home as a function of time shows that they started 3260 miles from home and are driving at 55 miles per hour.
part a:
D(12) = 3260 55(12)
D(12) = 3260 - 660
D(12) = 2600
Interpretation: After 12 hours of driving home, they are 2600 miles from home.
part b:
D(t) = 2490
3260 - 55t = 2490
-55t = -770
t = 14
Interpretation: When they are 2490 miles from home, they have driven for 14 hours.
Answer:
.
Step-by-step explanation:
Given : 9,540,000
To find : Write 9,540,000 in expanded form using exponents to show powers of 10.
Solution : We have given 9,540,000
Here 9 is at million place 9000000
5 is at hundred thousand place = 500,000.
4 is at tens thousand place = 40,000
We expanded it as
9, 000,000 + 500,000+40,000.
In term of power of 10.
.
Therefore,
.
Answer:
BRIANLIEST PLZ
N = 18.75
M = 22.5
Step-by-step explanation:
Need the ratio of money paid to each. We know how the ratio of time is divided so we can use this ratio to find the amount paid.
T = t1 + t2 = 2.5 + 3 = 5.5
r1 =2.5/5.5
r2 = 3/5.5
Nick = r1 * 41.25 = 18.75
Monica = r2 * 41.25 = 22.5
Answer:
g=18
Step-by-step explanation:
Isolate the variables by dividing each side by -2.5.
Answer:1,230.5
Reason: just learn how to divide
