What height on the wall will a 15 foot ladder reach if it is placed 3.5 feet from the base of the wall...???
umka2103 [35]

Answer:

14.6 feet

Step-by-step explanation:

Let the height of the ladder be the hypotenuse, the distance from the wall be the base and the height till the ladder reaches be the perpendicular.

Using Pythogoras theorem,

H^2 = p^2+b^2

p^2 = H^2-b^2

p = under root(H^2-b^2)

p = under root(225 - 12.25)

p = 14.6 feet

Please Help me with the questions in the picture
Likurg_2 [28]

Answer:

Dave and Anna:

1. Income highlight:

combined take home pay of $900/week

Total income: 4(900) - because 4 weeks in most months = $3600

-----------------------------

2. Expense highlights:

bi-weekly mortgage of $675

property taxes of $1800

Car expenses $160

Car insurance: $128

House insurance: $35

Saving for kids: $200

-------------

Expense calculations:

Mortgage bi-weekly = 675 x 2 = $1350/month

Property taxes = 1800/12 months/year = 150/month

everything else is already monthly

1350 + 150 + 160 + 128 + 35 + 200 = 2,023

---------------------------------------

income - expenses

$3600 - 2023 = $1,577 surplus

-----------------------------------------------------------------------------

Jacob:

Income highlights:

Canada Pension Plan $848/month

Old Age Security: $484/month

Total income: $1332

--------------------------

Expense highlights:

property tax: $3000/yr = $250/month

burial expenses: $100/month (for 6 more months)

golfing: $500/year = $41.67/month

bowling: $100/year = $8.33/month

Total expenses: 250 + 100 + 41.67 + 8.33 = 400

-----------------------------

Income - expenses:

1332 - 400 = $932 surplus
