What is the answer to this problem? Ignore the work. What is the correct answer?
yan [13]

Answer:

c = 42.5

Step-by-step explanation:

The legs of the triangle are a and b and the hypotenuse is c

Let a be the shorter leg

The hypotenuse is 5 more than the longest leg

c = b+5

The shortest leg is 20

a = 20

We can use the Pythagorean theorem

a^2 +b^2 = c^2

Substituting in what we know from above

20 ^2 + b^2 = (b+5)^2

FOIL  (b+5)^2 = b^2 +5b+5b +25 = b^2+10b+25

400 + b^2 = b^2+10b+25

Subtract b^2 from both sides

400+b&2-b^2 = b^2 -b^2 +10b+25

400 = 10b+25

Subtract 25 from both sides

400-25 = 10b+25-25

375 = 10b

Divide by 10

375/10 = 10b/10

37.5 = b

But we want to find c

c=b+5

c = 37.5+5

c = 42.5

find how long it will take for an investment sum of $40000 to generate simple interest of $8000 at 5% per annum​
guapka [62]

Answer:

It will take 4 years

Step-by-step explanation:

The formula of the simple interest is <em>I = Prt</em>, where

  • <em>P</em> is the investment
  • <em>r</em> is the annual rate in decimal
  • <em>t</em> is the time

∵ The investment is $40000

∴ <em>P</em> = 40000

∵ The simple interest is $8000

∴ <em>I </em>= 8000

∵ The rate of interest is 5%

∴ r = 5%

→ Change it to decimal by divide it by 100

∴ <em>r</em> = 5 ÷ 100 = 0.05

→ Substitute them in the formula above

∵ 8000 = 40000 × 0.05 × t

∴ 8000 = 2000t

→ Divide both sides by 2000

∴ 4 = t

∵ t is the time of investment

∴ It will take 4 years
