Answer:
25 months
Step-by-step explanation:
Plan A : $70 per month
Plan B : $50 per month + $500 as a one time cost.
So for A $70 a month would take 8 months to be at least $500
And for B it in those 8 months it would cost you $900
But we have to keep going up until they are equal
25*70 = 1750
(25*50) = 1250+500=1750
So yes 25 months is correct
Answer:
B. 7/2 miles per 1 hour
Step-by-step explanation:
The unit rate in this case ,means ,
the number of miles for every 1 hour
Since Taylor walks 7 miles in 2 hours
Then
He walks 7/2 miles in 1 hour
Thus
The unit rate that Taylor walks at is :
7/2 miles per 1 hour
Answer:
CD = 6 units
Step-by-step explanation:
In triangle ABC , AB is the hypotenuse then AB =√(BC)² + (AC)² = √(12)² + (9)² = 15
AB = 15
sin ∠ABC 12/15 = 0,8 Then arcsin (0.8) = 53,1°
∠ABC = 53,1° and ∠BAC = 36,9°
Now the hypotenuse is 15 units and we need to find the lenght of segment
CD. If we divide the hypotenuse in three equal segment (of lenght 5 each) we at the same time are dividing the ∠ACB ( 90°), in three equals angles of
30°.
If we now apply sin law
sin 30°/ 5 = sin 36,9°/CD
Then CD = 5 * sin 36.9° / sin 30° ⇒ CD =[ 5* (9/15) ] / 1/2
CD = 6 units
Answer:
V = 654.255 in^3
Step-by-step explanation:
6.7 in x 9.3 in x 10.5 in = 654.255 in^3 (cubic inches)
1. l = 12 - 2x w = 16 - 2x h = x
<span>2. V = (12 - 2x) (16 - 2x) (x) </span>
<span>3. Maximum Volume = 194 in.^3 when x = 2.26</span>
