The shortcut is the hypotenuse of a right triangle with legs 6 and 8, so 6²+8²=c²

36+64=c
100=c²
c=10.
so he traveled 6+8+10=24km

To find out how far Robert biked during this round trip, we need to find out what the short cut's length is. This can be found by using the Pythagorean Theorem. The Pythagorean Theorem states that for a triangle with sides a and b, and hypotenuse c, an equation relating the three is a² + b² = c². Now we can substitute the values we know and solve. The equation becomes:

6² + 8² = c²

c² = 100

c = 10

That means that the total distance that he biked is 10km + 8km + 6km = 24km.

You want to put some money in a simple interest account it pays 8% interest annually for 2 years you would like to earn 500 doll
Semmy [17]

You deposit some money into a bank account paying 8% simple interest per year. You received $500 in interest after 2 years. How much the deposit (principal) was?


Result


The principal was $3125.


Explanation


Find principal by using the formula I=P⋅i⋅t, where I is interest, P is total principal, i is rate of interest per year, and t is total time in years.


In this example I = $500, i = 8% and t = 2 years, so


IPPP=P⋅i⋅t=Ii⋅t=5000.08⋅2=3125

How do you solve st+3t=6
bonufazy [111]
You will factor out the common factor of t if you are solving for t. you will then divide both sides by (s+3) to make t the subject of the formula. for this question you can only get t in terms of s.
so:
st+3t=6
t(s+3)/(s+3)=6/(s+3)
t=6/(s+3)

if you are required to solve for s then you are going to subtract 3t from both sides. you can factorise 6-3t .you will then divide both sides by t to isolate s.for this question you can only get s in terms of t.so:

st+3t-3t=6-3t
st/t=2(3-t)/t
s=2(3-t)/t

About 115°

Step-by-step explanation:

  • By 2 pi r, total circumference is about 942
  • Length of an arc = 2 pi r (theta/360)
  • We needed to find theta(angle) here
  • Easily putting all the values gives us 115°
