Fabian bought 223 feet of wood to build
PilotLPTM [1.2K]

Answer:

111 boxes

Step-by-step explanation:

He bought 223 feet of wood

Each box will take 2 feet

To determine the total number of box he'll make from 223,

1 box = 2 feet of wood

X box = 223 feet of wood

X = (223 × 1) / 2

X = 111.5 box approximately 112 boxes

But technically, since its 111.5, he'll be able to make 111 boxes completely with 0.5 feet of wood left

Which of the following theorems proves that abc~def?
GaryK [48]

Answer:

D but read below.

Step-by-step explanation:

I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.

Jose invested $5000 into a fund with an interest rate of 4.8%. How much interest would he earn after 2 years? A) $240 B) $24,000
pogonyaev

Answer: C) $480  


Step-by-step explanation:

Given: Jose invested $5000 into a fund with an interest rate of 4.8%.

Therefore, Principal amount (P)$5000

Rate of interest = 4.8%

In decimal rate of interest(r)=0.048

Time (t)= 2 years

We know that the simple interest is given by

S.I.=Prt\\\Rightarrow\ S.I.=5000\times0.048\times2\\\Rightarrow\ S.I.=\$480

Hence, the interest after 2 years = $480
