Answer:
Area = 245 ft
(Width
Step-by-step explanation:
l = 5w
Where l is length and w is width.
We also know that the perimeter is 84 ft, so:
2l + 2w = 84
Now we can plug in 5w for l since we found the equality earlier:
2(5w) + 2w = 84
and then solve for w:
10w + 2w = 84
12w = 84
w = 7
so
l = 5 × 7
l = 35
The length is 35 and width is 7 so
the area of the rectangle is
Let s = northbound train
Then
2s = southbound train
:
Distance = time * speed
4s + 4(2s) = 600
:
4s + 8s = 600
:
12s = 600
:
s = 600/12
:
s = 50 mph is the northbound train
Then
2(50) = 100 mph is the southbound train
:
:
Check:
4(50) + 4(100) = 600
The formula of the future value of annuity ordinary
Fv=pmt [(1+r/k)^(kn)-1)÷(r/k)]
Fv future value
Pmt payment
R interest rate 0.0425
K compounded monthly 12
N time 10 years
If the payment 150
Fv=150×(((1+0.0425÷12)^(12
×10)−1)÷(0.0425÷12))
=22,381.089
If the payment 200
Fv=200×(((1+0.0425÷12)^(12
×10)−1)÷(0.0425÷12))
=29,841.452
How much more
29,841.45−22,381.09
=7,460.36
Answer:
Value C is equivalent to value a and b

Use the slope formula, do the same for each question.
Slope= y2-y1/x2-x1
Question 4: (-1,-2) and (1,0)
-1 is x1, -2 is y1
1 is x2, 0 is y2
0- -2=2 (0 subtract -2, two minus signs equal to an addition sign.)
1- -1=2
2/2= 1
The slope is 1.
