<span>Given cosA = 0.25. In order to find the value of angle A, we need to do the inverse cos of given value. A = cos^-1 (0.25) => A = 75.52 degrees. So the angle made by the two rays will be 75.52 degrees.</span>

2 1/2 + 4 1/4 = 6 3/4

6 3/4 = 27/4

54\div \frac{27}{4} = 54\times \frac{4}{27} = 2 \times 4 = 8

So Naomi earned $8 per hour that she mows the lawn.

Answer:

The amount after 6 months compounded quarterly is $1917.66 .

Step-by-step explanation:

Given as :

The principal amount deposited in account =  $1850

The bank applied rate of interest = r = 7.25% compounded quarterly

The time period of loan = t = 6 months = 0.5 years

Let the Amount after 6 months = $A

Now,<u> From quarterly Compound Interest method  </u>

Amount = principal × (1+\dfrac{\textrm rate}{4\times 100})^{4\times time}

Or, A = p × (1+\dfrac{\textrm r}{4\times 100})^{4\times t}

Or, A = $1850 × (1+\dfrac{\textrm 7.25}{4\times 100})^{4\times 0.5}

Or, A = $1850 × (1.018125)^{2}

Or, A = $1850 × 1.036578

∴ A = $1917.66

i.e A = $1917.66

So, The amount after 6 months = A = $1917.66

Hence, The amount after 6 months compounded quarterly is $1917.66 . Answer
