Two congruent 30-60-90 triangles are placed,as shown,so that they overlap partly and their hypotenuses coincide. If the hypotenu
Ede4ka [16]

Answer: The area common to both triangle is 31.77 sq. cm.

Step-by-step explanation:

Since we have given that

30-60-90 triangles are placed.

So, the ratio of sides would be

1:\sqrt{3}:2

Since Hypotenuse = 12 cm

So, it becomes,

2x=12\\\\x=\dfrac{12}{2}=6

So, Base would be

x=6\ cm

and Perpendicular would be

\sqrt{3}x=6\sqrt{3}

So, Area common to the both triangles would be

\dfrac{1}{2}\times base\times height\\\\=\dfrac{1}{2}\times 6\times 6\sqrt{3}\\\\=18\sqrt{3}\\\\=31.177

Hence, the area common to both triangle is 31.77 sq. cm.

Which conversion factors can be used to find the number of hours in a week? Select all that apply.
Archy [21]

Answer:

3rd and 4th options are correct that is 24 hours per day and 7 days per week.

Step-by-step explanation:

We need to find the conversion factors that can be used to find number of hours in a week.

We know that,

Number of hours in a day = 24

and

Number of days in a week = 7

So, Number of hours in 7 days = 24 × 7 = 168.

Therefore, 3rd and 4th options are correct that is 24 hours per day and 7 days per week.

Use the appropriate compound interest formula to compute the balance in the account after the stated period of time 24,000 is in
VLD [36.1K]

We know the compound interest formula is given by

A=P(1+\frac{r}{n} )^{nt}

Now, we have been given that 24,000 is invested for 2 years with an APR of 6​% and daily compounding. Thus, we have

P= 24,000\\
\\
t=2\\
\\
r=0.06\\
\\
n=365

On substituting these values in the above formula for the compound interest, we get

A=24000\left ( 1+\frac{0.06}{365} \right )^{365\cdot 2}\\
\\
\text{On solving this, we get}\\
\\
A=27059.7

Therefore, the balance in the account after 2 years is 27059.7
