Answer:
11 years
Step-by-step explanation:
7200 - 80x = 5000 + 120x
-5000 + 80x -5000 + 80x
2200 = 200x
11 = x
Tanα=h/x, tanß=h/(x+88)
solving both for x
x=h/tanα, x=h/tanß-88, since x=x
h/tanα=h/tanß-88
h/tanß-h/tanα=88
(htanα-htanß)/(tanα*tanß)=88
h(tanα-tanß)/(tanα*tanß)=88
h=88(tanα*tanß)/(tanα-tanß)
Since α=32 and ß=22...
h=88(tan32*tan22)/(tan32-tan22)
h≈85.3 feet
Answer: -0.5
<u>Step-by-step explanation:</u>
the x-value for A is 0.
the x-value for B is -2.
The total distance from A to B is -2.
= -0.5
A + -0.5
= 0 - 0.5
= -0.5
Answer:
2nd bank
Step-by-step explanation:
bank one:10*2=(20*3=60)
$1000+$100+$60=$1160
total after 3 years = $1160
bank two:$10*6=(60*3=180)
$1000+$180=$1180
total after 3 years = $1180
Answer:
$17.25
Step-by-step explanation:
Jeffrey earned $65 doing yard work.
He bought a pair of jeans costs = $31.25
and a sweatshirt costs = $16.50
Total amount he spent = 31.25 + 16.50 = $47.75
Now he left with money from his shopping = $65.00 - $47.75
= $17.25
Jeffrey set aside $17.25 for the gift.
